Item 1. Business.
Overview
PART I
Our mission is to develop therapies that empower the immune system to cure neurodegeneration and other diseases.
We are a clinical stage biopharmaceutical company pioneering immuno-neurology, a novel therapeutic approach for the treatment of
neurodegeneration. Immuno-neurology targets immune dysfunction as a root cause of multiple pathologies that are drivers of degenerative brain disorders.
We are developing therapies designed to counteract these pathologies simultaneously by restoring healthy immune function to the brain. Supporting our
scientific approach, our research and drug discovery platform enables us to advance a broad portfolio of product candidates, validated by human genetics,
which we believe will improve the probability of technical success over shorter development timelines. As a result, we have identified over 100 immune
system targets. Three product candidates, latozinemab (also referred to as AL001), AL002, and AL101 are in clinical development, and we continue to
develop our preclinical and research pipeline. We recently completed a prioritization review, focusing our development resources on our progranulin and
TREM2 programs and extending our cash runway through 2025. We are advancing our clinical product candidates and research pipeline with our existing
resources and in collaboration with our partners, Glaxo Wellcome UK Limited, a subsidiary of GlaxoSmithKline plc (GSK) and AbbVie Biotechnology,
Ltd. (AbbVie).
On July 1, 2021, we entered into a Collaboration and License Agreement with GSK (GSK Agreement) to collaborate on the global development
and commercialization of progranulin-elevating monoclonal antibodies, including latozinemab and AL101. Under the terms of the GSK Agreement, we
received $700 million in upfront payments, of which $500 million was received in the third quarter of 2021 and $200 million was received in the first
quarter of 2022. Together with GSK we are pursuing therapeutic candidates for frontotemporal dementia (FTD), Alzheimer’s disease (AD), Parkinson’s
disease, and amyotrophic lateral sclerosis (ALS).
Latozinemab modulates progranulin (PGRN), a key regulator of immune activity in the brain with genetic links to multiple neurodegenerative
disorders. Latozinemab is in development to treat FTD, a severe, rapidly progressing neurodegenerative disorder that affects 50,000 to 60,000 people in the
United States and roughly 110,000 people in the European Union.
Latozinemab is currently being studied in a global pivotal Phase 3 trial, INFRONT-3, for the potential treatment of adults at risk for or with
symptomatic FTD due to a progranulin gene mutation (FTD-GRN). We are preparing to engage with regulatory authorities in mid-2023. The purpose of the
meeting is to discuss statistical analysis plans based on emerging knowledge in the field that may enable us to complete the pivotal INFRONT-3 clinical
trial with fewer patients and/or a shorter treatment duration. The company is targeting a data readout from the INFRONT-3 trial in early 2025, pending
regulatory feedback. In prior clinical studies, latozinemab successfully demonstrated elevation of progranulin levels back to the normal range and
encouraging early signals of biomarker and clinical activity. Latozinemab has been well tolerated in healthy volunteers and FTD patients in our Phase 1a,
Phase 1b, and Phase 2 clinical trials.
In 2021, we presented data for latozinemab from our ongoing open-label Phase 2 clinical trial, INFRONT-2 in patients with FTD-GRN. INFRONT-2
was designed to establish the safety and tolerability of chronic administration of latozinemab at therapeutic doses, and to measure biomarkers of disease
and clinical outcomes. Treatment with latozinemab was well tolerated and restored PGRN in both plasma and cerebrospinal fluid (CSF) to levels seen in
healthy volunteer age-matched controls for the duration of treatment. Disease relevant lysosomal, inflammatory, and astrogliosis biomarkers trended toward
normalization over twelve months of treatment compared to baseline and age-matched controls, and mean levels of plasma and CSF neurofilament light
chain (NfL), remained stable over twelve months. Volumetric MRI suggested slowing of ventricular enlargement and brain atrophy in latozinemab-treated
patients compared to a matched historic control cohort of participants from the Genetic FTD Initiative (GENFI2) patient registry. Clinical outcome
assessments using the CDR® plus NACC FTLD-SB scale found that latozinemab treatment slowed clinical progression by 48% compared to the GENFI2
matched control cohort.
In March 2022, we presented additional data from the INFRONT-2 trial of latozinemab in FTD patients with a C9orf72 genetic mutation (FTD-
C9orf72), building on the results in patients with FTD-GRN. Clinical outcome assessments using the CDR® plus NACC FTLD-SB scale found that
treatment of FTD-C9orf72 patients with
3
latozinemab resulted in a trend toward a delay of approximately 54% in annualized disease progression compared to a matched control cohort from the
ALLFTD consortium. In addition, latozinemab treatment was well tolerated and resulted in a two- to three-fold increase in progranulin above physiological
levels in cerebrospinal fluid (CSF) and plasma respectively, and a decrease in the neurodegeneration biomarker GFAP. We intend to provide additional data
updates on the FTD-C9orf72 cohort in the second half of 2023.
In September 2021, we initiated a Phase 2 study of latozinemab in ALS patients with a C9orf72 mutation. However, in light of the evolving ALS
landscape, we closed that study to additional enrollment. We and GSK are currently evaluating plans for development of latozinemab in ALS.
AL101, the second product candidate in our PGRN portfolio, is designed to elevate progranulin levels, similar to latozinemab, for use in the
treatment of larger indications including Alzheimer’s disease and Parkinson’s disease. Mutations that moderately reduce the expression levels of PGRN are
associated with increased risk of developing Alzheimer’s disease and Parkinson’s disease. In animal models, increased PGRN levels have been
demonstrated to be protective for these diseases. In 2021, we presented interim data from our Phase 1 clinical trial testing the safety, tolerability,
pharmacokinetics, pharmacodynamics, and bioavailability of single doses of intravenously or subcutaneously administered AL101 in healthy volunteers.
AL101 increased progranulin levels in the periphery and the brain persisting for one month. AL101 was found to be well tolerated at all doses
administered. We completed enrollment of additional cohorts to test multiple doses of AL101 administered intravenously and subcutaneously.
In November 2022, we presented data from the multiple-dose cohorts of the Phase 1 study. We demonstrated that AL101 was well tolerated and
increased PGRN levels in plasma and CSF in a dose-dependent manner. The pharmacokinetic and pharmacodynamic profiles of AL101 support future
development in larger indications such as AD and PD. We and GSK plan to advance the AL101 program in 2023, with the initiation of an Asian
pharmacokinetic (PK) bridging study followed by a global Phase 2 clinical trial in early AD.
Our AL002 product candidate targets Triggering Receptor Expressed on Myeloid cells 2 (TREM2) to increase the functionality of TREM2 signaling
and enhance microglia cell activation. We are currently developing AL002 for the treatment of Alzheimer’s disease in collaboration with AbbVie.
In our Phase 1 clinical trial, AL002 demonstrated tolerability, target engagement, and proof-of-mechanism in the central nervous systems of healthy
volunteers. In January 2021, we initiated INVOKE-2, a randomized, controlled Phase 2 clinical trial of AL002, in which we initially aimed to enroll
approximately 265 participants with early Alzheimer’s disease. We now plan to add up to an additional 64 participants in the ongoing INVOKE-2 trial to
replace discontinuations, including APOE e4/e4 participants, from the study, as mentioned below. In January 2023, the first patient was enrolled and dosed
in a long-term extension (LTE) of our INVOKE-2 Phase 2 clinical trial. In February 2023, we and AbbVie amended the AbbVie agreement, which will
result in our receiving a $17.8 million milestone payment for the dosing of the first patient in an LTE study.
Amyloid Related Imaging Abnormalities (ARIA) have been observed in our ongoing INVOKE-2 Phase 2 clinical trial in AD. ARIA are MRI
findings suggestive of vasogenic edema or hemosiderin deposits. The incidence of ARIA has been shown to increase in AD patients with the administration
of certain Alzheimer's disease therapeutics, namely anti-β-amyloid antibodies. In our INVOKE-2 Phase 2 clinical trial, most ARIA cases were
asymptomatic and non-serious. However, a small number of ARIA-related serious adverse events occurred almost exclusively in patients with the APOE
e4/e4 genotype, as previously reported. To mitigate risks associated with ARIA, we voluntarily discontinued dosing and enrollment of APOE e4/e4
participants in our INVOKE-2 Phase 2 clinical trial. Following these changes, a small number of ARIA-related serious adverse events occurred in patients
who are non-homozygous for the APOE e4 allele. We continue to implement earlier MRI monitoring, consistent with recently published guidelines for
ARIA monitoring and management. We are conducting this study under the guidance of an Independent Data Monitoring Committee (IDMC), which is
allowed to review unblinded data and to make trial recommendations.
AL044 targets membrane-spanning 4-domains subfamily A (MS4A), a major risk locus for Alzheimer’s disease. MS4A gene family members encode
a transmembrane receptor protein that is expressed selectively on myeloid cells in the brain and associated with control of microglia functionality and
potentially with microglia viability. In September 2022, we commenced our first-in-human Phase 1 trial of AL044, with the intention of developing that
candidate in Alzheimer’s disease and potential orphan indications. Based on initial PK and tolerability data, we decided to close the trial. We are actively
pursuing a back-up MS4A program to develop an IND-ready candidate with a potentially improved dosing and tolerability profile.
4
The neuroimmune system of the brain is part of the body’s innate immune system, and based on our pioneering work in immuno-neurology, we have
identified potential oncology applications for several of our therapeutic programs. We believe that products focused on innate immune biology may
complement and expand the efficacy of current immuno-oncology drugs that target the adaptive immune system.
AL009, is one of our innate immuno-oncology product candidates. AL009 is a multi Siglec inhibitor that is designed to enhance both the innate and
adaptive immune system response to tumors by blocking a critical glycan checkpoint pathway that drives immune suppression. We continue to conduct
preclinical studies and technical activities on AL009. We own worldwide rights to AL009.
AL008 is another of our innate immuno-oncology product candidates. AL008 is an antibody designed to inhibit the CD47-SIRP-alpha (SIRPα)
pathway, a potent immune checkpoint pathway co-opted by tumors to evade the immune system. AL008 binds SIRP-alpha and has a novel dual mechanism
of action that inhibits immune suppression and promotes immune stimulation. We entered into a licensing agreement with Innovent Biologics (Innovent) in
2020, under which Innovent would develop and commercialize AL008 in China, while Alector would retain development and commercialization rights in
the rest of the world. Innovent will not be continuing development of AL008, and we intend to re-acquire the rights we granted to Innovent for the
development and commercialization of AL008. Innovent submitted an IND with the Chinese regulatory authorities, and Alector is in the process of
obtaining relevant materials and information from Innovent. Alector plans to evaluate data and documentation from that IND application to potentially
support an IND submission in the U.S.
As part of our efforts to advance our programs through clinical development and execute on the strategic approach outlined in the section titled
“Business – Our Strategy,” Alector from time to time may execute partnerships with other biopharmaceutical companies. To date we have executed three
licensing, co-commercialization, or co-development agreements for certain programs in our pipeline.
The Immune System is Central to Neurodegeneration
The loss of healthy immune function in the brain, due to cellular aging or mutations of genes that regulate key immune cells, underlies the onset and
progression of multiple neurodegenerative disorders. Genomic analyses have shown that there is a strong correlation between genetic mutations that
predispose individuals to neurodegeneration and dysfunction in the immune system. As a result of these genetic mutations, the brain’s immune function
deteriorates and subsequently would fail to carry out critical activities, which include:
•
•
•
•
•
clearing or counteracting pathological neurodegenerative proteins such as amyloid-beta, tau, alpha-synuclein, and TDP-43;
providing metabolic and functional support to nerve cells;
regulating synaptic connections;
protecting nerve cells by stimulating the regeneration of myelin sheaths around nerve fibers; and
controlling the neurotoxic activities of activated astrocytes and rogue microglia.
We believe that restoring the immune system’s ability to perform all of these vital functions in the brain is crucial to addressing neurodegeneration
given that past approaches focusing on single degenerative pathologies have had limited or no impact on disease progression.
The brain’s immune system undergoes gradual deterioration of functional characteristics as part of normal biological aging or due to harmful genetic
mutations that are linked to neurodegeneration and are associated with accelerated senescence of the brain immune cells. Based on our understanding of the
role of genetic mutations in neurodegeneration, we have designed our product candidates to target the mutated genes linked to neurodegeneration, with the
goal of slowing or reversing the deterioration of the brain’s immune cells to achieve therapeutic benefit. By restoring healthy immune function in the brain,
we believe we can simultaneously counteract the multiple independent pathologies responsible for neurodegeneration.
5
Our Strategy
Our goal is to develop therapies that harness the immune system to combat neurodegenerative diseases. The key tenets of our business strategy to
achieve this goal include:
•
•
Building a leading, fully-integrated company focused on delivering innovative immuno-therapies, validated by human genetics, for the
treatment of neurodegeneration. We believe that building a fully integrated research, development, and ultimately commercial company
will enable us to develop therapies more rapidly and efficiently for patients and realize the full potential of our immuno-neurology approach
and discovery capabilities.
Applying our proprietary capabilities to rapidly advance our product candidates through clinical proof-of-concept studies and beyond.
We are focused on maximizing the probability of success of our product candidates by leveraging immunology, neurobiology, and human
genetics, as well as our state-of-the-art bioinformatics, to enable better and earlier target selection. In addition, we are also focused on a
biomarker-driven approach, including proprietary tools and assays, to confirm target engagement, inform patient selection, and follow
clinical outcomes.
• Maximizing the therapeutic potential of our targets and product candidates. Given the central physiological roles played by the distinct
targets of our product candidates, we believe that there is significant potential for us to address multiple indications with single targets. Our
goal is to expand the therapeutic and commercial potential of our targets and product candidates to additional indications, such as immuno-
oncology. However, we will remain disciplined about advancing this strategy, leveraging our discovery capabilities to inform expansion
areas of maximum value and highest probability of success.
•
Continuing to focus on discovering new targets and product candidates, validated by human genetics, to fulfill the full potential of our
insights and platform. Our discovery capabilities are central to our efforts to rapidly identify new product candidates with compelling
clinical promise. We will continue to invest in our research and discovery efforts, including evolving our proprietary analytical tools and
assays, to further investigate several of our identified immune system targets as well as generate additional targets and product candidates.
Our Approach
The Role of the Innate Immune System and Microglia in Neurodegeneration
Significant evidence in the last decade has shown that neurodegenerative diseases, such as Alzheimer’s disease, Parkinson’s disease, FTD, and ALS,
are linked to a dysfunctional brain immune system. In contrast to the dual adaptive and innate components that characterize the broader human immune
system, the brain’s immune system consists primarily of innate immune cells, known as microglia. These brain resident macrophages account for 10% to
15% of all cells found within the brain and are responsible for many aspects of brain health and maintenance. As the key innate immune cells in the brain,
microglia respond to infection and damage, clear cell debris and pathological proteins, nurture neurons and the brain support cells, and control the number
and functionality of inter-neuronal connections. Microglia have been our focus and new scientific advances have made it possible to understand how these
key innate immune cells in the brain represent a crucial focal point for potentially treating or preventing neurodegenerative diseases.
6
Figure 1. Our clinical stage neurodegenerative disease programs
Significant Scientific Data Support Our Hypothesis
Understanding how the brain’s immune cells affect its structure and function, in both normal and diseased states, is in our view, the key to
understanding many neurological diseases. Human genetic evidence has supported the importance of the interactions between the brain and the innate
immune system. For example, most of the top risk genes for Alzheimer’s disease, identified using genetic linkage studies, candidate gene analysis, genome-
wide association studies (GWAS), and whole-genome or whole-exome sequencing, regulate immune function in the brain. Many of these risk genes have
been shown to express predominantly in microglia and to control the function of these cells.
Microglia have been shown to be key cells in overall brain maintenance, health, and function and are the brain’s first line of immune defense. These
innate immune cells are tooled with “microglial sensomes” which enable them to constantly survey brain cells to identify and respond to subtle signs of
pathology or dysfunction. Microglia scavenge the brain for toxic misfolded proteins, cell debris, damaged or unnecessary nerve cells, dysfunctional or aged
synapses, and infectious agents. In addition, microglia support the generation of new neurons and synapses and remodel neuronal circuits. Microglia also
control the survival and function of astrocytes and oligodendrocytes, the main brain support cells which control brain metabolism and blood supply and
replenish aged or damaged nerve fibers after injury. Further, microglia have been shown to modulate the permeability of the blood brain barrier allowing
access to peripheral immune cells, to assist against infection or injury. Microglia can also change their morphology, functionality, and number in response
to changing brain environment.
Analysis of gene transcription at the single-cell level in microglia from normal and diseased brains revealed that multiple microglia subtypes exist
which may respond to specific disease pathologies in the brain. Our product candidates are designed to recruit microglia subtypes by targeting microglia
check-point proteins that control their survival, proliferation, migration, and function. This allows us to differentially modulate microglia activity as needed
to counteract a given degenerative brain disorder.
7
Findings in the fields of human genetics, immunology, and neuroscience have indicated that as a result of normal aging or genetic mutations, the
beneficial functions of the microglia deteriorate leading to dysfunction of neuronal connections, massive death of neurons and neurodegeneration.
We believe our therapies that focus on harnessing the power of microglia may improve neurodegenerative disease outcomes either as standalone
therapies or in combination with anti-amyloid beta targeted therapies. Anti-amyloid beta antibodies mark misfolded aggregates and recruit microglia to
remove them. Our therapies, including those in our progranulin franchise, are expected to enhance microglia's ability to remove misfolded proteins in
conjunction with anti-amyloid beta antibodies that tag these proteins.
Figure 2. Our checkpoint therapies anticipated to act independently and in combination
Our Research and Discovery Platform
Our research and drug discovery platform leverages human genetic datasets, advanced tools in bioinformatics and imaging, and insights in
neurodegeneration and immunology to: (1) identify immune system targets that play a critical role in the development of multiple neurodegenerative
diseases, and rapidly develop antibody therapeutics to these targets, (2) interrogate and prioritize those targets for activity using biomarkers and related
proprietary assays and preclinical models, and (3) clinically test product candidates, including in genetically defined patient populations that may be most
likely to respond to treatment. We believe that these platform capabilities provide us with the tools to solve the conceptual and technical challenges
associated with development of drug candidates for neurodegeneration.
We rely on proprietary immuno-neurology bioinformatics algorithms and methodologies to analyze large genetic datasets from diseased and healthy
individuals, brain-based gene expression profiling and proteomics, and human pathology. These proprietary capabilities allow us to rapidly identify
tractable targets, pharmacodynamic biomarkers, and patient populations associated with aberrant immune function which lead to neurodegeneration.
Specifically, the priorities of our platform efforts are:
•
Target Selection. Our target selection capabilities address a wide array of factors that we believe inform efficient, optimized therapeutic
outcomes, including genetic and mechanistic rationale. We leverage our bioinformatics expertise to identify genetic mutations in the brain
immune system that we believe increase the risk of disease onset and progression. We combine our bioinformatic approaches with in-house
functional genomics to discover and validate genetic mutations and targets of interest. We utilize state of the art techniques such as CRISPR
Activation and Inhibition, single cell transcriptomics, proteomics, metabolomics, microscopic and biochemical readouts in relevant in vitro
systems such as hiPSC microglia and in vivo systems such as mouse/rat models to elucidate the
8
immune dysfunction caused by these mutations. We then seek to engineer immune modulating antibody product candidates to functionally
counteract the harmful consequence of these genetic mutations. We leverage in vitro and in vivo functional tools to validate the activity of
our product candidates and their ability to cross the blood brain barrier enough to be therapeutically effective.
•
•
•
Biomarker Selection. We are able to identify and employ molecular biomarkers, assays, and imaging techniques that are tailored to our
product candidates to confirm target engagement and quantify their impact, allowing us to potentially interpret the clinical impact of our
compounds earlier than would be expected using traditional clinical measures.
Patient Selection. We utilize genetic screening and biomarkers in certain orphan disease programs to better align a patient’s specific
diagnosis with the targeted intervention in our clinical studies.
Biologics Discovery. We pursue a comprehensive antibody discovery strategy using in vivo (multiple species, hybridoma and single B cell
technology) and in vitro directed evolution (phage and yeast display) approaches. We leverage our advanced antibody engineering
capabilities to design and optimize biotherapeutics.
We employ gene expression profiling, proteomics, brain imaging, and data on disease pathology as well as our own preclinical and clinical data to
continually refine our proprietary immuno-neurology algorithms and methodologies. Using our drug discovery platform capabilities to identify targets that
are validated by human genetics, disease biomarkers, and responsive patient populations, we believe that we are positioned for greater probability of
technical success on more efficient timelines relative to historical drug development in neurodegeneration.
Our Pipeline Programs
Figure 3. The following table highlights our clinical programs, preclinical and research programs, BBB technologies, and IP portfolio.
Our clinical programs include latozinemab, AL101, and AL002. In addition, we continue to pursue a number of preclinical and research programs in
our pipeline for indications including Alzheimer’s disease, Parkinson’s disease, and oncology.

Our Progranulin Program
Our first development program is focused on modulating levels of PGRN, a key regulator of microglia function in the brain with strong genetic links
to FTD and other neurodegenerative disorders. Individuals carry two copies of the PGRN gene that function together to produce healthy levels of PGRN
throughout the body. Mutations in both copies of the PGRN gene lead to a neurodegenerative disease called neuronal ceroid lipofuscinosis, which is
typified by childhood dementia, vision loss, epilepsy, and death. Mutations in a single copy of the PGRN gene result in a drop of between 50% and 70% in
the level of PGRN and consequently lead to development of FTD with about 90% penetrance by 75 years of age. Moreover, large scale human genetic
studies suggest that regulatory mutations in the gene for PGRN, which lead to a more modest decrease in the level of PGRN, increases the risk for
Alzheimer’s disease and Parkinson’s disease, making PGRN a significant risk gene for these disorders as well.
Healthy levels of PGRN are associated with many cellular processes that include normal microglial activities, neuronal survival, and lysosome
function. PGRN deficiency disrupts microglia-neuronal homeostasis in the brain and promotes neurodegeneration through the release of cytotoxic
cytokines and complement factors by dysfunctional microglia. Moreover, these microglia activate astrocytes, which in turn, damage neurons. Thus, lack of
PGRN leads to disrupted health and function of both neurons and microglia and if not corrected, leads to rapid neurodegeneration.
Figure 4. PGRN deficiency disrupts homeostasis between microglia and neurons and promotes neurodegeneration during aging.
SORT1 Controls PGRN Levels in the Body
Human and mouse genetic studies have identified the neurotrophic factor PGRN degrading receptor Sortilin (SORT1) as a major negative regulator
of PGRN levels in plasma and the brain. SORT1 is a sorting receptor on the cell surface and on the endoplasmic reticulum-Golgi apparatus within the cell.
SORT1 binds to extracellular PGRN in the plasma and brain and transports it into cells for degradation by the lysosome resulting in decreasing levels of
extracellular PGRN. SORT1 deficiency increases PGRN plasma and brain levels by two to three-fold in mouse models, while variants that modestly reduce
expression of SORT1 increase the level of PGRN in humans.
Moreover, genetic loss of SORT1 in mice does not lead to the adverse effects associated with genetic loss of PGRN, and PGRN continues to
function as expected in the absence of SORT1. These studies and others have indicated to us that blocking SORT1 with a pharmacological agent could be a
safe and effective approach in increasing the level of functional PGRN in the brain.
We have developed two distinct product candidates that target SORT1, latozinemab and AL101, designed to increase PGRN levels in the brain of
patients to counteract the damage sustained due to low PGRN levels in neurodegenerative disorders. Our first product candidate, latozinemab, is intended
to treat orphan disorders, including genetic forms of FTD such as in patients that are missing a functional copy of the PGRN gene (FTD-GRN). Our second
PGRN product candidate, AL101, is intended to treat widely prevalent neurodegenerative disorders such as Alzheimer’s disease and Parkinson’s disease, in
addition to FTD. We have partnered with GSK to
10
develop and commercialize our PGRN product candidates. For more information on our collaboration with GSK see the section titled “Business—Strategic
Alliance with GSK.”
Latozinemab and AL101 received orphan drug designation from the U.S. Food and Drug Administration (FDA) for the treatment of FTD, as well as
Fast Track designation for the treatment of patients with FTD-GRN. Generally, if a product that has orphan drug designation subsequently receives the first
FDA approval for a particular active ingredient for the disease for which it has such designation, the product is entitled to orphan drug exclusivity. This
means that the FDA may not approve any other NDA or BLA application to market the same drug or biologic for the same indication for seven years,
except in limited circumstances such as a showing of clinical superiority to the product with orphan exclusivity, if FDA revokes the orphan drug
designation, or if FDA finds that the holder of the orphan exclusivity has not assured the availability of sufficient quantities of the orphan product to meet
the needs of patients with the disease or condition for which the drug was designated. Even though the FDA has approved orphan drug status for
latozinemab and AL101 for treatment of FTD, the FDA can still approve other drugs that have a different active ingredient for use in treating FTD.
Furthermore, orphan drug exclusivity does not prevent the FDA from approving another marketing application for the same drug product for a different
indication before the expiration of the orphan exclusivity period. Orphan drug designation does not convey any advantage in, or shorten the duration of, the
regulatory review and approval process. Fast Track designation is designed to facilitate the development and expedite the review of therapies which treat
serious conditions and fill an unmet medical need. Programs with Fast Track designation may benefit from early and frequent communications with the
FDA, potential priority review, and additionally, a rolling submission of the marketing application.
Latozinemab for the Treatment of FTD
Our first product candidate, latozinemab, is a human recombinant monoclonal antibody that increases the levels of PGRN in the brains of FTD-GRN
patients. Administered via intravenous peripheral infusion, latozinemab functions by blocking the SORT1 degradation mechanism for PGRN and
increasing the circulating half-life of the functional PGRN in the brain. We are initially developing latozinemab for the treatment of symptomatic FTD due
to a progranulin gene mutation.
Overview of FTD
FTD is a rapidly progressing and severe degenerative brain disease with no approved treatment. FTD is a form of dementia found most frequently in
individuals less than 65 years old at time of diagnosis. Patients with FTD exhibit a range of personality-related symptoms, including compulsive behavior,
lack of restraint, apathy, and anxiety as well as language and behavioral problems. The rate of disease progression in FTD is faster than in Alzheimer's
disease. Average life expectancy in FTD patients is seven to 10 years after the start of symptoms. FTD symptoms have an insidious onset with clinical
symptoms usually appearing between 45 to 65 years of age at an average age of 58. Hence, FTD is considered an early-onset dementia as compared to late-
onset Alzheimer’s disease, and is more common than Alzheimer’s disease in early-onset dementia under the age of 60 years.
Figure 5. MRI of frontal and temporal atrophy in FTD.
Although FTD was poorly understood and thought to be rare, over the past decade the scientific community has gained a knowledge about the
biology of FTD as well as an awareness of disease prevalence. FTD affects roughly 50,000 to 60,000 people in the United States and roughly 110,000 in
the European Union. There are
11
multiple heritable forms of FTD; to date, researchers have identified over 70 inherited loss of function mutations in PGRN that lead to FTD. FTD-GRN
patients represent 5% to 10% of all people with FTD.
Figure 6. Mutations in a single copy of PGRN result in a 50% or greater decrease in the level of PGRN and result in a greater than 90%
probability of developing FTD. (1) Rhinn H, Tatton N, McCaughey S, Kurnellas M, Rosenthal A. Progranulin as a therapeutic target in neurodegenerative
diseases. Trends in Pharmacological Sciences. 2022 Aug; 43(8):641-652. DOI: 10.1016/j.tips.2021.11.015. PMID: 35039149. (2) Dement Geriatr Cogn
Disord Extra 2016;6:330-340
In FTD-GRN patients, inhibition of SORT1 through latozinemab represents a potential mechanism to compensate for the over 50% reduction of
PGRN. Latozinemab is intended to reduce the ability of SORT1 to bind to and degrade PGRN, leading to increases in the levels of PGRN by increasing its
circulating half-life. We have tested our PGRN program antibodies in various animal models, healthy volunteers, and FTD-GRN patients and have achieved
significantly elevated, long-lasting levels of PGRN in the brain after intravenous administration.
Figure 7. Mechanism of action for our PGRN programs. Latozinemab binds to SORT1 and prevents degradation of PGRN, increasing its
circulating half-life significantly. A similar mechanism of action is also applicable for AL101.

Our PGRN Product Candidates Development Plan and Clinical Trial Results to Date
Latozinemab is currently being studied in a global pivotal Phase 3 trial in both at-risk and symptomatic participants with FTD-GRN, named
INFRONT-3. The randomized, double-blind, placebo-controlled trial currently plans to enroll up to 180 FTD-GRN mutation carriers across approximately
50 clinical sites in the United States, Canada, Europe and Australia. Symptomatic and at-risk participants will be randomized to receive latozinemab or
placebo intravenously every four weeks. Participants will also be given the option to continue receiving treatment in an open-label extension (OLE) study.
In June 2022, the first participant from the INFRONT-3 study was enrolled in the optional OLE designed to assess the long-term safety, tolerability, and
efficacy of latozinemab in participants who have completed 96 weeks in the INFRONT-3 study, and enrollment in the OLE continues. The primary
endpoint of our pivotal Phase 3 trial is to measure the effect of latozinemab on clinical decline by utilizing the CDR® plus NACC FTLD-SB assessment,
which evaluates clinical impairments in behavior, language, memory, judgment, and functional activities in trial participants. In addition, our Phase 3 trial
will assess secondary clinical endpoints, multiple biomarkers and safety. We are preparing to engage with regulatory authorities in mid-2023. The purpose
of the meeting is to discuss statistical analysis plans based on emerging knowledge in the field that may enable us to complete the pivotal INFRONT-3
clinical trial with fewer patients and/or a shorter treatment duration. The company is targeting a data readout from the INFRONT-3 trial in early 2025,
pending regulatory feedback.
In 2021, we presented data for latozinemab from our ongoing open-label Phase 2 INFRONT-2 clinical trial. INFRONT-2 was designed to establish
the safety and tolerability of chronic administration of latozinemab at therapeutic doses, and the study also measured biomarkers of disease and clinical
outcomes. Results from up to twelve symptomatic FTD-GRN patients treated over twelve months in an open-label study showed that latozinemab was well
tolerated. Treatment with latozinemab restored PGRN in both plasma and CSF to levels seen in healthy volunteer age-matched controls for the duration of
treatment.
Figure 8. Latozinemab restores PGRN in plasma and CSF to levels seen in healthy volunteer age-matched controls
In addition to assessing PGRN levels in plasma and CSF, we evaluated disease-associated proteins, including lysosomal (e.g., CTSD, LAMP1),
complement (C1QB), and astrogliosis (GFAP) biomarkers along with NfL. In our Phase 2 trial results presented in 2021, many of these disease-relevant
biomarkers of lysosomal function, complement activation, astrogliosis, and neuronal health trended toward normalization or remained stable over twelve
months of treatment compared to baseline and age-matched controls.

Phase 2 trial. (1) The control group included N = 44 age-matched procured control samples, (2) at Baseline N = 11 FTD-GRN participants, (3) at 6 months
treatment with latozinemab N = 9 FTD-GRN participants, and (4) at 12 months treatment with latozinemab N = 10 FTD-GRN participants
Figure 10. Latozinemab treatment decreases Glial Fibrillary Acidic Protein (GFAP) levels towards normal levels in plasma and CSF of
asymptomatic FTD-GRN participants enrolled in our Phase 2 trial, suggesting a reduction in astrogliosis.
Figure 11. NfL levels in plasma and CSF are stable over 12 months in latozinemab-treated symptomatic FTD-GRN participants enrolled in our
Phase 2 trial.
To provide context for the clinical outcomes observed in the open-label INFRONT-2 trial, a matched control cohort of ten FTD-GRN participants
from the GENFI2 consortium was created using the propensity score matching technique. These ten GENFI2 patients were identified based on the CDR®
NACC FTLD SB at baseline and further
14
refined by matching based on age, NfL levels, and clinical diagnosis at baseline, all done on a blinded basis without access to longitudinal results.
Using volumetric MRI, we found a greater than 10% reduction in the atrophy rates in favor of the latozinemab treated FTD-GRN patient population
for the whole brain and frontotemporal cortex measures, and an approximately 50% reduction in the rate of ventricular enlargement, relative to the matched
control GENFI2 cohort of FTD-GRN.
Figure 12. vMRI data suggest slowing of ventricular enlargement and brain atrophy in latozinemab treated FTD-GRN patients enrolled in our
Phase 2 trial.
In our Phase 2 trial, we also assessed clinical outcomes using the CDR® plus NACC FTLD-SB scale. The CDR® plus NACC FTLD-SB is the
Clinical Dementia Rating Scale plus National Alzheimer’s Coordinating Center frontotemporal lobar degeneration sum of boxes rating scale developed for
patients with FTD. Latozinemab treatment was estimated to slow disease progression by 48% in 12 patients at twelve months.

matched GENFI2 controls. Random Coefficient Model with Repeated Measurements including baseline & all available post-baseline measurements up to
12 months.
In prior clinical trials, latozinemab was well tolerated and demonstrated proof of mechanism. In our Phase 1a trial (n=50) in healthy volunteers,
latozinemab was well tolerated. In our Phase 1b portion of the trial (n=14) in FTD-GRN patients, there was a statistically significant increase in PGRN
levels relative to baseline when compared to pooled placebo in plasma and in CSF at the prespecified follow-up time point. In addition, results from these
15
Phase 1 studies showed that latozinemab was generally well tolerated, with no drug-related serious adverse events or dose-limiting adverse events reported
in the trial.
Figure 14. Latozinemab restores PGRN levels in symptomatic and asymptomatic FTD-GRN patients back to the normal range as seen in healthy
volunteers.
Potential Additional Applications for Our PGRN Program
In order to treat any other neurodegenerative diseases and the broader FTD patient population with latozinemab, we will be required to conduct
additional clinical studies to obtain the applicable approvals for that specific patient population. We enrolled an additional genetic subset of FTD patients
(FTD-C9orf72) in our open-label Phase 2 clinical trial of latozinemab and may expand to additional indications in the future.
In March 2022, we presented additional data from the INFRONT-2 trial of latozinemab in FTD patients with a C9orf72 genetic mutation (FTD-
C9orf72), building on the results in patients with FTD-GRN. Clinical outcome assessments using the CDR® plus NACC FTLD-SB scale found that
treatment of FTD-C9orf72 patients with latozinemab resulted in a trend toward a delay of approximately 54% in annualized disease progression compared
to a matched control cohort from the ALLFTD consortium.

matched ALLFTD controls. ALLFTD - One post-baseline timepoint at approximately 12 months.

Figure 16.Latozinemab treatment decreases GFAP levels towards normal levels in plasma and CSF of FTD-C9orf72 participants enrolled in our
Phase 2 trial.
Both decreased progranulin levels and mutations in the chromosome 9 open reading frame 72 (C9orf72) gene are associated with abnormal
accumulation of the TAR DNA-binding protein 43 (TDP-43). Excess aggregation of TDP-43 in brain cells is thought to lead to neuronal cell death and is
associated with multiple neurodegenerative diseases, including both FTD-C9orf72 and ALS.
In 2021 we initiated a Phase 2 clinical trial evaluating the safety, tolerability, pharmacokinetics and pharmacodynamics of latozinemab in people
with ALS who carry a C9orf72 mutation. In preclinical studies using multiple models of acute and chronic neurodegeneration, increasing progranulin
levels has been shown in the literature to reverse and be protective against TDP-43 pathology. In light of the evolving ALS landscape, we closed that study
to additional enrollment. We and GSK are currently evaluating plans for development of latozinemab in ALS.
Overview of ALS
ALS is a devastating, fatal, progressive neurodegenerative disorder. In ALS, the motor neurons in the brain and spinal cord die, resulting in
weakness, muscle atrophy, paralysis and frequently, cognitive impairment, before resulting in death from respiratory failure. Each year, more than 5,000
people in the U.S. are diagnosed with ALS and an estimated 31,000 patients in the U.S. are living with the disease. Mutations within multiple genes,
including the C9orf72 gene, are believed to cause the disease. Such mutations can lead to an accumulation of TDP-43 in the cells resulting in neuronal
death and an estimated 95% of ALS cases are linked to TDP-43 pathology. Approximately 40-50% of all familial ALS and up to 10% of sporadic ALS
cases are attributed to the C9orf72 mutation. Currently approved medications for ALS confer only a modest survival benefit and new treatment options are
urgently needed.
AL101 for the Treatment of Alzheimer’s Disease and Parkinson’s Disease
We are developing a second product candidate in our PGRN programs, AL101, a human recombinant monoclonal antibody that also targets SORT1
and is designed to elevate progranulin levels similar to latozinemab. We are developing AL101 to target large chronic neurodegenerative diseases, such as
Alzheimer’s disease and Parkinson’s disease.
Polymorphic mutations that moderately reduce the expression levels of PGRN have been shown to increase the risk of developing Alzheimer’s
disease and Parkinson’s disease, and increased PGRN levels have been demonstrated to be protective for these diseases in animal models.
In 2022, we presented interim data from our Phase 1 clinical trial testing the safety, tolerability, pharmacokinetics, pharmacodynamics, and
bioavailability of single doses of intravenously or subcutaneously administered AL101 in healthy volunteers. AL101 increased progranulin levels in the
periphery and the brain persisting for one month. AL101 was found to be well tolerated at all doses administered. We completed enrollment of additional
cohorts to test multiple doses of AL101 administered intravenously and subcutaneously. AL101 was well tolerated and increased PGRN levels in plasma
and CSF in a dose-dependent manner. In the two multiple dose
17
(MD) cohorts, 27 healthy volunteers received either AL101 30 mg/kg IV every four weeks (q4w) for a total of four doses [n=11] or AL101 300 mg
subcutaneously (SC) every two weeks (q2w) for a total of seven doses [n=13]. Three volunteers received MD IV placebo. AL101 was found to be
generally well tolerated following MD IV (q4w) and SC (q2w) administrations. Consistent with previously presented data following single doses, AL101
was measurable in the CSF following multiple IV and SC doses. MD administration of AL101 increased plasma and CSF PGRN levels, with a higher
elevation observed in the AL101 30 mg/kg MD IV group than in the AL101 300 mg MD SC group. Multiple IV doses of AL101 at 30 mg/kg increased and
maintained the levels of PGRN at approximately 160% to 200% (2.6- to 3-fold) above baseline in plasma and approximately 80% (1.8-fold) above baseline
in the CSF. The PK and PD profile of AL101 following single and multiple IV doses support future development in chronic neurodegenerative conditions
such as AD and PD.
Figure 17. AL101 treatment increased PGRN levels in healthy volunteers enrolled in our Phase 1 trial.
Overview of Alzheimer’s Disease
Alzheimer’s disease is a chronic neurodegenerative disease that usually starts slowly in people over 65 years of age and worsens over time. It is the
most common cause of dementia, accounting for 60% to 70% of all cases. The most common early symptom of Alzheimer’s disease is difficulty in
remembering recent events. As the disease advances, symptoms can include problems with language, disorientation, mood swings, loss of motivation,
failure to manage self-care, and behavioral issues. As a person’s condition declines, they often withdraw from family and society. Gradually, bodily
functions are lost, leading to death. Although the speed of progression can vary, the typical life expectancy following diagnosis is eight to ten years.
While estimates of the prevalence of Alzheimer’s disease vary, the Alzheimer’s Association estimates that in 2022, there were more than 6.5 million
Americans ages 65 and older suffering from Alzheimer’s disease and that number is projected to nearly triple by 2060. Alzheimer’s disease is the sixth
leading cause of death in the United States and the fifth-leading cause of death for those ages 65 and older.
In addition to its debilitating effect on patients’ cognition and day-to-day functioning, Alzheimer’s disease places a significant burden on the
healthcare system. According to the Alzheimer’s Association, the aggregate cost of care in 2022 for patients with Alzheimer’s disease and other types of
dementia in the United States was estimated to be $321 billion, nearly two-thirds of which is borne by the Medicare system. Total payments for health care,
long-term care, and hospice care for people with Alzheimer’s and other dementias in the United States are projected to increase to more than $1.1 trillion in
2050.
Overview of Parkinson’s Disease
Parkinson’s disease is a long-term degenerative disorder of the central nervous system that mainly affects the motor system. Early in the disease, the
most obvious symptoms are shaking, rigidity, slowness of movement, and difficulty with walking. Cognitive and behavioral problems may also occur.
Dementia becomes common in the advanced stages of the disease. Depression and anxiety are also common, occurring in more than a third of people with
Parkinson’s disease. Other symptoms include sensory, sleep, and emotional problems. Parkinson’s disease
18
typically occurs in people over the age of 60. The average life expectancy following diagnosis is between three to 10 years after the onset of symptoms.
There is no disease modifying treatment for Parkinson’s disease, and the options for patients are limited to treatments that improve symptoms. Initial
treatment is typically with the anti-Parkinson’s drug medication levodopa, with dopamine agonists being used once levodopa becomes less effective. As the
disease progresses and neurons continue to be lost, these medications become less effective while at the same time they produce a complication marked by
involuntary writhing movements.
According to the Parkinson’s Foundation, more than 10 million people worldwide are living with Parkinson’s disease. Approximately 90,000
Americans are diagnosed with Parkinson’s disease each year and an estimated 1.2 million Americans will be living with Parkinson’s disease by the year
2030. According to the Parkinson’s Foundation, the combined direct and indirect cost of Parkinson’s, including treatment, social security payments and lost
income, is estimated to be nearly $52 billion per year in the United States alone and is estimated to cost approximately $80 billion annually in the United
States by 2037.
Our TREM2 Program
TREM2 is a transmembrane receptor protein that is expressed on a subset of innate immune cells and selectively on microglia in the brain. TREM2
on microglia cells is thought to promote improved cell migration to the site of injury, improved cell survival, increased phagocytosis, and increased cell
proliferation. Rare individuals with homozygous TREM2 mutations, or mutations on both chromosomal copies, may develop neurodegeneration by the age
of 40 with an average lifespan of 10 years following diagnosis. A gene variant in one of the two copies of TREM2 is found to increase the risk of
Alzheimer’s disease by three-fold. Not only do mutations in a single copy of TREM2 increase the risk of Alzheimer’s disease significantly, but Alzheimer’s
disease patients with TREM2 mutations exhibit an earlier onset of symptoms by three years and an increased rate of brain volume loss compared to
individuals without such mutations. Evidence also suggests that a gain of function mutation leading to increased expression of TREM2 confers a protective
phenotype against Alzheimer’s disease.
The discovery of strong genetic linkage of TREM2 to Alzheimer’s disease in 2013 was one of the first examples in which large scale genomic
analyses were used to identify a rare gene variation and link it to an increase in the risk of late-onset Alzheimer’s disease.
TREM2 binds to membrane lipids and lipoproteins such as Apolipoprotein E (ApoE) which are normally found in the brain. Polymorphisms in the
gene for ApoE are also known to significantly increase the risk of development of Alzheimer’s disease and are the single highest risk factor for
Alzheimer’s disease.
AL002 for the Treatment of Alzheimer’s Disease
Our product candidate, AL002, is a humanized, TREM2 activating, monoclonal antibody that is intended to be delivered by intravenous, peripheral
infusion. AL002 is a microglia cell regulator that modulates the TREM2 receptor and is being developed for the treatment of Alzheimer’s disease in
collaboration with AbbVie. For more information on our collaboration with AbbVie see the section titled “Business—Strategic Alliance with AbbVie.”
19
Figure 18. Mechanism of action of our TREM2 activating product candidate AL002.
There are currently no cures for Alzheimer’s disease. Two therapies directed at the underlying pathology of the disease have been approved by the
FDA with evidence of reduction of amyloid beta plaques and potential clinical benefit. Other classes of approved therapies are for symptomatic treatment
including, acetylcholinesterase inhibitors and glutamatergic modulators. These drugs are designed to help preserve neuronal communication, but only
provide temporary benefit and do not slow or halt neuronal death. In addition, antidepressants and antipsychotics are often prescribed off-label to treat the
symptoms of severe Alzheimer’s disease in patients suffering from agitation, aggressive behaviors, psychosis, and depression.
Recent drug candidates under development for Alzheimer’s disease include those focused on blocking synthesis, enhancing clearance or
disaggregating misfolded amyloid-beta or tau proteins in the brain, reversing chronic inflammation, and repairing vascular dysfunction, metabolic
dysregulation, as well as neurotoxicity. Almost all of these candidates were designed to target just one of the multiple Alzheimer’s disease pathologies, and
most of these drug candidates have so far failed to demonstrate significant benefit.
Although amyloid-beta plaques and tau protein in the brain represent physical pathologies of the disease and are believed to cause a loss of neuronal
connectivity in the brain and neuronal death, recent scientific data paints a more complex picture. We believe more efficacious therapies will likely require
addressing multiple pathologies including those associated with microglial failure.
Our TREM2 Clinical Program
In January 2021, we initiated our Phase 2 trial in Alzheimer’s disease patients in early stages of the disease. The randomized, double-blind, placebo-
controlled, dose-ranging, multi-center Phase 2 trial was intended to enroll approximately 265 participants with early AD at up to 90 sites globally, and we
now plan to add up to an additional 64 participants in the ongoing INVOKE-2 trial to replace discontinuations, including APOE e4/e4 participants, from
the study. The primary endpoint of our Phase 2 trial will measure disease progression utilizing the Clinical Dementia Rating Sum of Boxes (CDR-SB). The
trial will also measure multiple fluid and imaging biomarkers, and assess several secondary clinical, pharmacokinetic and pharmacodynamic endpoints, as
well as safety to generate data enabling pivotal Phase 3 studies. In January 2023, the first participant from the INVOKE-2 study was enrolled and dosed in
an LTE of our Phase 2 clinical trial. We plan to complete INVOKE-2 trial enrollment in the third quarter of 2023, with top-line data expected by the fourth
quarter of 2024.
20
ARIA have been observed in our ongoing INVOKE-2 Phase 2 clinical trial in AD. ARIA are MRI findings suggestive of vasogenic edema or
hemosiderin deposits. The incidence of ARIA has been shown to increase in AD patients with the administration of certain Alzheimer's disease
therapeutics, namely anti-β-amyloid antibodies. In our INVOKE-2 Phase 2 clinical trial, most ARIA cases were asymptomatic and non-serious. However, a
small number of ARIA-related serious adverse events occurred almost exclusively in patients with the APOE e4/e4 genotype, as previously reported. To
mitigate risks associated with ARIA, we voluntarily discontinued dosing and enrollment of APOE e4/e4 participants in our INVOKE-2 Phase 2 clinical
trial. Following these changes, a small number of ARIA-related serious adverse events occurred in patients who are non-homozygous for the APOE e4
allele. We continue to implement earlier MRI monitoring, consistent with recently published guidelines for ARIA monitoring and management. We are
conducting this study under the guidance of an IDMC, which is allowed to review unblinded data and to make trial recommendations.
In 2019, we completed the Phase 1a portion (n=56) of a clinical trial in healthy volunteers with AL002. AL002 was well tolerated in the single
ascending dose part of our Phase 1 trial. In addition, a dose dependent and statistically significant change in both soluble TREM2 (sTREM2) and
downstream biomarkers for microglia functionality in CSF were observed upon treatment, indicating both target engagement and proof-of-mechanism in
healthy volunteers. Based on the tolerability observed in our Phase 1a healthy volunteer trial, as well as encouraging biomarker data, we initiated the Phase
1b portion of the trial with AL002 in people with Alzheimer’s disease. However, based on the data collected to date in preclinical studies as well as in
healthy volunteers, and in alignment with our partner AbbVie, we closed enrollment in the Phase 1b trial, which was impacted by the COVID-19 pandemic,
and shifted to initiating our Phase 2 trial. In our Phase 1 clinical trial, AL002 demonstrated tolerability, target engagement, and proof-of-mechanism in the
central nervous systems of healthy volunteers and Alzheimer's disease patients.
Figure 19. In healthy volunteers, a dose dependent decrease in sTREM2 and an increase in CSF-1R, a biomarker of microglial activation was
observed in our AL002 Phase 1 clinical trial. CSF samples were taken from the five highest dose cohorts. The data shown are derived from analysis of
CSF samples from 34 healthy volunteers (* denotes p<0.05 by T-test, *** denotes p<0.001 by T-test).
Our TREM2 Preclinical Data
AL002 binds to TREM2 on the surface of microglia and is designed to optimize microglial activity through the phosphorylation of Spleen
Associated Tyrosine Kinase (Syk). With prominent academic collaborators, we demonstrated that AL002s, an antibody that is functionally similar to
AL002 but cross-reacts to the mouse TREM2, can normalize gene expression signature associated with Alzheimer’s disease and reduce pathology in a
mouse model of Alzheimer’s disease. Furthermore, AL002c, a form of AL002 with a murine Fc region, was shown to induce microglial proliferation, and
amyloid plaque compaction and decrease dystrophic neurites associated with damaged neurons in a severe amyloid mouse model that expresses either the
normal or genetic risk variant of the human TREM2.

Our MS4A Program
MS4A is among the most prominent genetic risk loci for late-onset Alzheimer’s disease. Risk variants of the MS4A locus are associated with an
increase in the prevalence of Alzheimer’s disease and a decrease in the age of onset. MS4A gene family members encode a transmembrane receptor protein
that is expressed selectively in microglia in the brain and is associated with control of microglia functionality and potentially with microglia viability. Our
AL044 product candidate was designed to counteract the risk variants of the MS4A gene family and to functionally convert the risk variants of the MS4A
gene family to the protective variant. In September 2022, we commenced our first-in-human Phase 1 trial of AL044, with the intention of developing that
candidate in Alzheimer’s disease and potential orphan indications. Based on initial PK and tolerability data, we decided to close the trial. We are actively
pursuing a back-up MS4A program to develop an IND-ready candidate with a potentially improved dosing and tolerability profile.
Alector's Emerging Innate Immuno-oncology Pipeline
Immuno-oncology
We are also expanding our discovery platform to other indications, such as the field of immuno-oncology. We believe that products focused on
innate immune biology will complement and expand the efficacy of current immuno-oncology drugs that target the adaptive immune system. Microglia
display similar gene expression and function to the cells of the peripheral, or non-brain, innate immune system. These peripheral innate immune cells such
as macrophages, monocytes, NK cells, and others, likely play a significant role in multiple chronic diseases including cancer, inflammation, and
autoimmune disorders. We are leveraging our expertise in the innate immune system to develop additional innate immune checkpoint focused programs,
including programs targeting the SIRP protein family and the Siglec protein family, for peripheral disorders, particularly cancer.
22
Figure 21. Neurodegeneration and cancer converge at the innate immune system. We believe substantial functional overlap exists between tumor
associated macrophages and microglia.
AL009, Our Multi Siglec Program
AL009, is one of our innate immuno-oncology product candidates. AL009 is a multi Siglec inhibitor that is designed to enhance both the innate and
adaptive immune system response to tumors by blocking a critical glycan checkpoint pathway that drives immune suppression. AL009 is a targeted sialic
acid trap that is designed to interrupt Siglec inhibitory signals preferentially on innate immune cells in order to confer therapeutic benefit in oncology
indications. We continue to conduct preclinical studies and technical activities on AL009. We own worldwide rights to AL009.
AL008, Our SIRP-alpha Program
AL008 is a monoclonal antibody that inhibits SIRP-alpha. AL008's dual mechanism of action non-competitively antagonizes the CD47-SIRP-alpha
pathway by inducing the internalization and degradation of the inhibitory receptor on macrophages to relieve immune suppression (shut down "don't eat me
signal") while also engaging Fc gamma receptors to promote immuno-stimulatory pathways that drive anti-tumor immunity. By targeting the SIRP-alpha
receptor, which is primarily expressed on myeloid cells, we believe AL008 may be able to avoid the antigen sink and on-target clinical adverse effects
observed with certain CD47-targeting agents. Furthermore, AL008 is designed to bind selectively to SIRP-alpha without cross-reacting to other SIRP
family members, such as SIRP-gamma. This specificity allows AL008 to antagonize the inhibitory CD47-SIRP-alpha pathway while preserving the T cell-
activating CD47-SIRP-gamma pathway. We entered into a licensing agreement with Innovent in 2020, under which Innovent would develop and
commercialize AL008 in China, while Alector would retain development and commercialization rights in the rest of the world. Innovent will not be
continuing development of AL008, and we intend to re-acquire the rights we granted to Innovent for the development and commercialization of AL008.
Innovent submitted an IND with the Chinese regulatory authorities, and Alector is in the process of obtaining relevant materials and information from
Innovent. Alector plans to evaluate data and documentation from that IND application to potentially support an IND submission in the U.S.
Combination Therapies
Our therapies are also likely to act in conjunction with each other or with other experimental drugs that are designed to remove pathological
proteins. Therapies such as antibodies against amyloid-beta, tau filaments or misfolded alpha-synuclein protein are designed to tag the pathological proteins
and recruit microglia to dispose of the drug/pathological protein complex. Aging microglia are less likely to perform this function effectively, and our
immuno-neurology therapies could ameliorate this deficiency. We intend to explore various combination strategies in preclinical models and will, in the
future, consider moving this strategy into the clinic based upon results from preclinical models.

Strategic Alliance with GSK
Overview
In July 2021, we entered into a Collaboration and License Agreement with GSK, pursuant to which we and GSK will collaborate on the global
development and commercialization of progranulin-elevating monoclonal antibodies, including latozinemab and AL101. The GSK Agreement became
effective on August 17, 2021.
Under the terms of the GSK Agreement, we received $700 million in upfront payments, of which $500 million was received in August 2021 and
$200 million was received in January 2022. In addition, we may be eligible to receive up to an additional $1.5 billion in clinical development, regulatory,
and commercial launch-related milestone payments. In the United States, the parties will equally share profits and losses from commercialization of
latozinemab and AL101. Outside of the United States, we will be eligible for double-digit tiered royalties.
The parties will jointly develop latozinemab and AL101, with GSK conducting Phase 3 clinical trials for Alzheimer’s disease and Parkinson’s
disease and other non-orphan indications. Development costs will be shared 60% by GSK and 40% by us, except that we will solely bear the development
costs of the initial Phase 2 clinical trials under the development plan, and the parties will share manufacturing development costs equally.
In the United States, the parties will be jointly responsible for commercialization of latozinemab and AL101, with us leading the commercialization
for orphan indications and GSK leading the commercialization for Alzheimer’s disease and Parkinson’s disease and other non-orphan indications. Outside
of the United States, GSK will be solely responsible for commercialization of latozinemab and AL101 for all indications. We may opt out of the sharing of
development costs and of profit and losses from commercialization in the United States on a product-by-product basis. In such case, we will no longer
conduct development or commercialization of that product and the Company will receive tiered royalties on net sales in the United States instead of a share
of profits or losses. GSK may terminate the agreement with 180 days' notice at any time, but the Company does not need to repay any portion of the
payments received.
Governance. The collaboration is governed by a joint steering committee (JSC). The JSC may establish additional subcommittees to oversee
particular projects or activities. Subject to limitations specified in the GSK Agreement, if the applicable governance committee is unable to make a decision
by consensus and the parties are unable to resolve the issue through escalation to specified senior executive officers of the parties, then the issue is
escalated to an alternative dispute resolution subject to final decision-making rights retained by each party.
Exclusivity. During the term of the GSK Agreement, each of Alector and GSK are subject to exclusivity requirements prohibiting certain activities
outside of the GSK Agreement directed to targets under the GSK Agreement.
Intellectual Property. Ownership of intellectual property created in connection with the GSK Agreement is generally determined on the basis of
inventorship. Generally, we have the first right to control prosecution and maintenance of licensed patents, including patents developed solely by us or
jointly by the parties, in the United States, and GSK has the first right to control prosecution and maintenance of such patents outside the United States.
GSK has the first right to prosecute infringement of such patents by certain third-party products. The parties shall mutually agree on which party shall
control the defense against claims that a product developed under either of the programs that are the subject of the GSK Agreement infringes third-party
intellectual property rights, with the party against whom such claims have been filed having the first right to defend in the absence of such mutual
agreement.
Term and Termination. At any point during the term of the GSK Agreement, after a specified notice period, GSK can terminate the GSK
Agreement in its entirety for convenience. Additionally, GSK or we can terminate the GSK Agreement in connection with a material breach of the GSK
Agreement by the other party that remains uncured for a specified period of time.
Strategic Alliance with AbbVie
Overview
In October 2017, we entered into the Co-Development and Option Agreement with AbbVie. The primary goal of our global strategic collaboration
with AbbVie is to co-develop and commercialize therapeutics to treat Alzheimer’s and other neurodegenerative diseases.
24
Under the AbbVie Agreement, we granted AbbVie an exclusive option to global development and commercialization for our TREM2 and SIGLEC
3 programs. The terms of the AbbVie Agreement included initial upfront payments of $205.0 million and $20.0 million from the sale of shares of our stock.
We are responsible for the design and execution of Phase 1 and Phase 2 studies, taking advantage of our significant in-house expertise in running clinical
trials in Alzheimer’s disease. In June 2022, AbbVie provided notice of termination with respect to the SIGLEC 3 program. In February 2023, we and
AbbVie amended the AbbVie agreement, which will result in our receiving a $17.8 million milestone payment for the dosing of the first patient in a long-
term extension study. If AbbVie exercises its option for the TREM2 program, we will receive $250.0 million. Additionally, under the terms of the AbbVie
Agreement, we will be eligible to earn up to an additional $225 million in milestone payments related to the regulatory approval for up to three indications.
Following AbbVie’s option exercise for the TREM2 program, we may opt out of sharing in development costs and profits or and instead receive a tiered
royalty on sales of products. Following AbbVie's exercise of an option for the TREM2 program, AbbVie would be responsible for certain development
activities and global commercialization, taking advantage of its global clinical trial expertise and commercialization networks. Through this partnership, we
aim to leverage the strengths of both organizations efficiently to best achieve the desired outcome.
Exercise of options. AbbVie may exercise its option for the TREM2 program at any time until the expiration of the option term. The option term
ends following a fixed period after AbbVie’s receipt of the data package after completion of Phase 2 clinical trials that includes certain information relating
to the TREM2 program’s research and development activities. If AbbVie fails to exercise its option during the option term for a product candidate, we will
retain all rights to the TREM2 program. If AbbVie exercises its option for the TREM2 program, then AbbVie will lead development and commercialization
activities worldwide. Once AbbVie opts in with respect to a given product candidate, AbbVie must use commercially reasonable efforts to develop and
commercialize the corresponding product globally.
Governance. The collaboration is governed by a joint steering committee (JSC). The JSC may establish additional subcommittees to oversee
particular projects or activities. Subject to limitations specified in the AbbVie Agreement, if the applicable governance committee is unable to make a
decision by consensus and the parties are unable to resolve the issue through escalation to specified senior executive officers of the parties, then the issue is
escalated to an alternative dispute resolution subject to final decision-making rights retained by each party.
Exclusivity. During the term of the AbbVie Agreement, we and AbbVie are subject to exclusivity requirements prohibiting certain activities outside
of the AbbVie Agreement directed to targets under the AbbVie Agreement.
Intellectual Property. Ownership of intellectual property created in connection with the AbbVie Agreement is generally determined on the basis of
inventorship. Generally, each party has the first right to prosecute and maintain its own patents. We generally have the first right to prosecute and maintain
joint patents prior to AbbVie’s exercise of its option for the program relating to such patent, and AbbVie has the right following its exercise of such option.
AbbVie has the first right to prosecute any infringement of jointly held patents developed under the AbbVie Agreement and our patents that are licensed
under the AbbVie Agreement. Additionally, AbbVie has the sole right to prosecute its own patents. AbbVie has the first right to defend against claims that a
product developed under the TREM2 program that are the subject of the AbbVie Agreement infringe third-party intellectual property rights.
Term and Termination. At any point during the term of the AbbVie Agreement, including during the research, development, and clinical trial
process, AbbVie can terminate the AbbVie Agreement in its entirety, or with respect to TREM2 program under the AbbVie Agreement, for convenience. In
that event, all rights related to the TREM2 program revert to us. Additionally, AbbVie or we can terminate the AbbVie Agreement in connection with a
material breach of the AbbVie Agreement by the other party that remains uncured for a specified period of time.
Adimab Collaboration Agreements
Overview – 2014 Adimab Collaboration Agreement (2014 Adimab Agreement)
In 2014, we entered into the 2014 Adimab Collaboration Agreement (the 2014 Adimab Agreement). Under the 2014 Adimab Agreement, we are
required to fund, and we and Adimab LLC (Adimab) are required to use commercially reasonable efforts to conduct, certain research to discover and
optimize antibodies directed against
25
targets selected by us. We are developing antibodies discovered by Adimab in our latozinemab and AL101 product candidates, and we are developing an
antibody optimized by Adimab in our AL002 product candidate.
Governance. Our collaboration with Adimab is governed by a research committee consisting of at least two representatives from each party. The
research committee prioritizes among research programs and prepares and finalizes new proposed research plans, among other activities. If the research
committee is unable to make a decision by consensus and the parties are unable to resolve the issue through escalation to specified senior executive officers
of the parties, then either party may seek arbitration of the matter.
Exclusivity. Pursuant to the 2014 Adimab Agreement, each party is subject to limitations on its ability to use information or material provided by the
other outside the scope of the collaboration.
Intellectual Property. Ownership of intellectual property arising from the research is generally owned by the party that invents or creates the
applicable intellectual property, although certain categories of intellectual property are specifically assigned to one party or the other. For example, patent
rights relating to improvements to Adimab’s background platform technology that are invented in the course of the research are assigned to Adimab. Prior
to our exercise of the option described below, we and Adimab each grant the other a non-exclusive license to the relevant intellectual property we own to
allow each party to carry out its rights and obligations in connection with the research; and except for Adimab’s retained rights to continue using and
licensing its own libraries, each party agrees not to practice or license the patents arising out of the research that it owns for any purpose other than to carry
out its rights and obligations in connection with the research. Generally, each party has the obligation to prosecute, maintain, defend, and enforce its own
patents, but we are subject to certain contractual restrictions on our ability to prosecute, practice, and license certain of our patents that arose out of the
research. These restrictions are lifted once we exercise the option described below as to such patents.
Exercise of Options. The 2014 Adimab Agreement granted us an exclusive option to obtain certain rights relating to a specified number of
antibodies discovered or optimized by Adimab directed against the targets we selected. The option extended to ownership of patent rights specifically
covering the sequences of such antibodies, and the right to obtain worldwide, royalty-bearing, sublicensable licenses under certain technology owned or
developed by Adimab to research, develop, make, have made, use, sell, offer to sell, import and export such antibodies and products based on such
antibodies for all human therapeutic, prophylactic and diagnostic uses. These licenses are exclusive, except as to Adimab background and platform
technology and Adimab’s retained rights to continue using and licensing its own libraries, as to which the licenses are non-exclusive. We have confirmed
with Adimab in writing that key patents we have filed relating to the programs partnered with AbbVie claim inventions owned solely by us, and do not
include any such background or platform technology of Adimab. All of our options under the 2014 Adimab Agreement have either expired, are in the
process of being exercised, or, with respect to multiple targets and hundreds of antibodies (including the target programs partnered with AbbVie), have
already been exercised. Upon our exercise of the option with respect to a target, we are subject to an obligation to devote commercially reasonable efforts
to commercialize products using the optioned rights to such target. The assigned and licensed patent rights we obtained from these option exercises are
described in more detail above under the section titled “Business—Intellectual Property.”
Financial terms. We fund Adimab’s research in connection with our collaboration, in accordance with the terms and limitations described in the
2014 Adimab Agreement. We also have potential milestone payments per program for use of antibodies and low- to mid-single digit royalty payments for
commercial sales of products incorporating such antibodies. However, if we enter into any transaction granting rights to the inventions or sell products
created as a result of a collaboration with a third party, we have a choice to pay a share of the resulting revenue instead of royalties from such sales.
Term and Termination. We are able to terminate the 2014 Adimab Agreement, in its entirety or with respect to a products or antibodies directed to
particular targets, on three months prior written notice to Adimab. In addition, either party can terminate the 2014 Adimab Agreement in its entirety, or,
subject to certain limitations, with respect to specific optioned rights, for material breaches that remain uncured after 90 days’ notice to the breaching party.
In the case of a termination before expiration of the 2014 Adimab Agreement, we would have certain continuing payment obligations to Adimab, or would
be required to adhere to certain restrictions as to the fruits of the collaboration. The 2014 Adimab Agreement expires on the twelfth anniversary of the first
commercial sale of the products created under the collaboration, on a product-by-product and country-by-country basis. The licenses we and Adimab
granted to each other do not survive, subject to certain limitations.
26
Overview—2019 Adimab Collaboration Agreement (2019 Adimab Agreement)
In 2019, we entered into another Adimab collaboration agreement (the 2019 Adimab Agreement). Under the 2019 Adimab Agreement, we are
required to fund, and we and Adimab are required to use commercially reasonable efforts to conduct, certain research to discover and optimize antibodies
directed against targets selected by us. We have not yet identified any research programs under the 2019 Adimab Agreement.
Governance. Our collaboration with Adimab is governed by a research committee consisting of at least two representatives from each party. The
research committee facilitates communication regarding research under the 2019 Adimab Agreement and has the limited authority to amend a research plan
in a manner not substantially affecting the resources required from a party. If the research committee is unable to make a decision by consensus, no decision
will be taken.
Exclusivity. Pursuant to the 2019 Adimab Agreement, each party is subject to limitations on its ability to use information or material provided by the
other outside the scope of the collaboration.
Intellectual Property. Ownership of intellectual property arising from the research is generally owned by the party that invents or creates the
applicable intellectual property, although certain categories of intellectual property are specifically assigned to one party or the other. Certain intellectual
property relating to Adimab’s background platform technology including any improvements thereto that are invented in the course of the research are
assigned to Adimab. Patents covering antibodies that are the subject of the collaboration are owned by us; however, prior to our exercise of the option
described below, we are prohibited from practicing such patents for any purpose other than to perform our research obligations under the 2019 Adimab
Agreement. Upon the expiration of the option term described below, in the event we elect not to exercise our option right with respect to an antibody,
ownership of such patents is transferred to Adimab. Prior to our exercise of the option described below, we and Adimab each grant the other a non-
exclusive license to the relevant intellectual property we own to allow each party to carry out its rights and obligations in connection with the research.
Generally, each party has the obligation to prosecute, maintain, defend, and enforce its own patents, but we are subject to certain contractual restrictions on
our ability to prosecute, practice, and license certain of our patents that arose out of the research. These restrictions are lifted once we exercise the option
described below as to such patents.
Exercise of Options. The 2019 Adimab Agreement granted us an exclusive option to obtain certain rights relating to a specified number of
antibodies discovered or optimized by Adimab directed against the targets we selected. The option extends to ownership of the applicable optioned
antibody, and the right to obtain worldwide, royalty-bearing, sublicensable non-exclusive licenses under certain technology owned or developed by Adimab
to research, develop, make, have made, use, sell, offer to sell, import and export such antibodies and products based on such antibodies for all human
therapeutic, prophylactic and diagnostic uses. Upon our exercise of the option with respect to a target, we are subject to an obligation to devote
commercially reasonable efforts to commercialize products using the optioned rights to such target.
Financial terms. We fund Adimab’s research in connection with our collaboration, in accordance with the terms and limitations described in the
2019 Adimab Agreement. We are also responsible for certain development fees and, in the event we exercise the option right, we are obligated to pay an
option fee. We also have potential milestone payments per product for use of antibodies, subject to certain limitations on total payments owed on any given
target, and low-single digit royalty payments for commercial sales of products incorporating such antibodies.
Term and Termination. We are able to terminate the 2019 Adimab Agreement, in its entirety or with respect to a products or antibodies directed to
particular targets, on 60 days’ prior written notice to Adimab. In addition, either party can terminate the 2019 Adimab Agreement in its entirety for material
breaches that remain uncured after 90 days’ notice to the breaching party. In the case of a termination before expiration of the 2019 Adimab Agreement, we
would be prohibited from using the fruits of the collaboration. The 2019 Adimab Agreement expires, on a product-by-product and country-by-country
basis, on the later of the twelfth anniversary of the first commercial sale of such product in such country and expiration of the last patent covering such
product in such country, or, in the event no product is optioned under the 2019 Adimab Agreement, upon the last to expire option period. Upon expiration,
the licenses Adimab granted to us with respect to products for which we have exercised our option will continue on a non-exclusive, royalty-free basis.
27
Overview—2021 Adimab Collaboration Agreement (2021 Adimab Agreement)
In 2021, we entered into another Adimab collaboration agreement (the 2021 Adimab Agreement). Under the 2021 Adimab Agreement, we were
required to fund antibody engineering research programs with respect to targets selected by us. The 2021 Adimab Agreement also granted us an exclusive
option to obtain a specified number of engineered sequences discovered or optimized by Adimab and directed against the targets that we selected. We
selected one target, which was the subject of a research program conducted by the parties. We did not exercise our option to obtain any engineered
sequences in connection with that research program, and we did not nominate any additional targets for additional research programs. The 2021 Adimab
Agreement expired at the end of the option period for the research program that was conducted.
Manufacturing
We must manufacture our product candidates for clinical trial use in compliance with cGMP regulations. The cGMP regulations include
requirements relating to organization of personnel, buildings and facilities, equipment, control of components and drug product containers and closures,
production and process controls, packaging and labeling controls, holding and distribution, laboratory controls, records and reports, and returned or
salvaged products. The manufacturing facilities for our product candidates must meet cGMP requirements and FDA or comparable foreign regulatory
authority’s satisfaction before any product is approved for human clinical trial use. Our third-party manufacturers will also be subject to periodic
inspections of their respective facilities for general cGMP compliance by the FDA and other foreign authorities. These inspections may include review of
procedures and operations used in the testing and manufacture of our products to assess compliance with applicable regulations.
We do not currently have the infrastructure or internal capability to manufacture our product candidates for use in clinical trials and
commercialization. We rely, and expect to continue to rely, on third-party cGMP manufacturers or our collaboration partners for the production of our
products for human clinical trials in compliance with FDA and other foreign authority regulations for such products. We rely on CDMOs to manufacture
and supply our preclinical and clinical materials to be used during the preclinical and clinical development of our product candidates. As part of our broad
manufacturing strategy to expedite the manufacturing of our product candidates and minimize manufacturing risk, we currently have established
relationships with several CDMOs for the manufacturing of our drug substance or product candidates.
We do not have long-term supply agreements and we purchase our required drug product through development manufacturing services agreement.
We expect to continue to rely on third-party manufacturers or our collaboration partners for the commercial supply of any of our product candidates for
which we obtain marketing approval. We have personnel with significant technical, manufacturing, analytical, quality, regulatory, including cGMP, and
project management experience to oversee our third-party manufacturers and to manage manufacturing and quality data and information for regulatory
compliance purposes.
Failure to comply with statutory and regulatory requirements subjects a manufacturer to possible legal or regulatory action, including warning
letters, the seizure or recall of products, injunctions, consent decrees placing significant restrictions on or suspending manufacturing operations and civil
and criminal penalties. Contract manufacturers often encounter difficulties involving production yields, quality control and quality assurance, as well as
shortages of qualified personnel. Any of these actions or events could have a material impact on the availability of our products.
Commercialization Plan
We do not currently have any approved drugs and we do not expect to have any approved drugs in the near term. Therefore, we have no sales,
marketing or commercial product distribution capabilities and have no experience as a company in marketing drugs. When, and if any of our product
candidates are approved for commercialization, we intend to develop a commercialization infrastructure for those products in the United States, Europe,
Asia, and potentially in certain other key markets. We may also rely on partnerships, such as our AbbVie and GSK collaborations, to provide
commercialization infrastructure, including sales and marketing and commercial distribution.
28
Intellectual Property
Our success depends in part on our ability to obtain and maintain proprietary protection for our product candidates, technology and know-how, to
operate without infringing the proprietary rights of others and to prevent others from infringing our proprietary rights. Our strategy is to seek to protect our
proprietary position by, among other methods, pursuing and obtaining patent protection in the United States and in jurisdictions outside of the United States
related to our proprietary technology, inventions, improvements and product candidates that are important to the development and implementation of our
business. Our patent portfolio is intended to cover our product candidates and related components, their methods of use and processes for their
manufacture, our proprietary reagents and assays and any other inventions that are commercially important to our business. We also rely on trademarks as
well as trade secret protection of our confidential information and know-how relating to our proprietary technology, platforms and product candidates. We
believe that we have substantial know-how and trade secrets relating to our technology and product candidates.
As of December 31, 2022, our patent portfolio contains over 50 families, which include 42 issued patents and over 500 pending patent applications
that are directed to over 20 different targets and/or technologies and that are solely owned or we have rights to exclusive licenses by us. For our product
candidates, we generally pursue multilayered patent protection covering the composition of matter based on binding epitopes of the product candidates on
the target protein, functional characteristics of the product candidates, degenerative sequence of the product candidates, and/or specific sequence of the
product candidates. In addition to composition of matter coverage, we also generally pursue claims directed to methods of making, nucleic acids,
formulations, and methods of use of the product candidates. The method of use claims further include claims directed to patient selection criteria,
biomarkers, disease subgroups, pharmacodynamic and clinical end-points, and dosage regimes. As further described below, we intend to strengthen the
patent protection of our product candidates and technologies through additional patent application filings.
PGRN Programs
We own six patent families directed to our PGRN programs, latozinemab and AL101, which include seven issued U.S. patents, covering the
compositions and uses of our PGRN program product candidates. The first two patent families are expected to expire in 2036, the third patent family is
expected to expire in 2039, the fourth patent family is expected to expire in 2040, the fifth patent family is expected to expire in 2041, and the sixth patent
family is expected to expire in 2042, in all cases excluding any patent term adjustments and any patent term extensions.
TREM2 Program
We own seven patent families directed to the TREM2 program, which include two issued U.S. patents, covering the compositions and uses of our
TREM2 program product candidates. The first patent family is expected to expire in 2035, the second patent family is expected to expire in 2036, the third
patent family is expected to expire in 2038, the fourth patent family is expected to expire in 2040, the fifth and sixth patent families are expected to expire
in 2041, and the seventh patent family, assuming that the necessary non-provisional patent applications are timely filed and all other applicable
requirements are satisfied for the U.S. provisional patent application, is expected to expire in 2043, in all cases excluding any patent term adjustments and
any patent term extensions.
MS4A Program
We own two patent families directed to the MS4A program covering the compositions and uses of our potential MS4A program product candidates.
The first patent family is expected to expire in 2039 and the second patent family is expected to expire in 2040.
The term of individual patents depends upon the legal term for patents in the countries in which they are granted. In most countries, including the
United States, the patent term is generally 20 years from the earliest claimed filing date of a non-provisional patent application in the applicable country. In
the United States, a patent’s term may, in certain cases, be lengthened by patent term adjustment, which compensates a patentee for administrative delays
by the U.S. Patent and Trademark Office in examining and granting a patent, or may be shortened if a patent is terminally disclaimed over a commonly
owned patent or a patent naming a common inventor and having an earlier expiration date. The Drug Price Competition and Patent Term Restoration Act of
1984 (Hatch-Waxman Act) permits a patent term extension of up to five years beyond the expiration date of a U.S. patent as partial compensation for the
length of time the drug is under regulatory review while the patent is in force. A patent
29
term extension cannot extend the remaining term of a patent beyond a total of 14 years from the date of product approval, only one patent applicable to
each regulatory review period may be extended and only those claims covering the approved drug, a method for using it or a method for manufacturing it,
may be extended.
Similar provisions are available in the European Union and certain other foreign jurisdictions to extend the term of a patent that covers an approved
drug. In the future, if and when our product candidates receive approval by the FDA or foreign regulatory authorities, we expect to apply for patent term
extensions on issued patents covering those products, depending upon the length of the clinical trials for each drug and other factors. Expiration dates
referred to above are without regard to potential patent term extension or other market exclusivity that may be available to us.
We also rely, in some circumstances, on trade secrets to protect our technology. However, trade secrets can be difficult to protect. We seek to protect
our proprietary technology and processes, in part, by confidentiality agreements with our employees, consultants, scientific advisors and contractors. We
also seek to preserve the integrity and confidentiality of our data and trade secrets by maintaining physical security of our premises and physical and
electronic security of our information technology systems.
Competition
The biotechnology and pharmaceutical industries, including in the neurodegenerative disease field, are characterized by rapidly advancing
technologies, strong competition and an emphasis on intellectual property. We face substantial competition from many different sources, including large
and specialty pharmaceutical and biotechnology companies, academic research institutions, governmental agencies and public and private research
institutions. Some of the pharmaceutical and biotechnology companies that are currently pursuing the development of products for the treatment of the
neurodegenerative disease indications for which we have research programs, including FTD, Alzheimer’s disease, Parkinson’s disease, and ALS, include
large companies with significant financial resources, such as Biogen, Eli Lilly, Merck and Roche Holding AG. Some of these companies are pursuing
product candidates for the same or similar indications to ours and in some cases acting on the same targets or through comparable mechanisms of action.
We believe that the key competitive factors affecting the success of any of our product candidates will include efficacy, safety profile, method of
administration, cost, time to market, level of promotional activity and intellectual property protection.
We anticipate our product candidates will compete with therapies approved for treating the symptoms of neurodegenerative diseases and therapies
approved or currently in clinical studies intended to halt or slow the progression of neurodegenerative disease that are being developed by a number of
companies and institutions.
Government Regulation
Government authorities in the United States at the federal, state and local level and in other countries regulate, among other things, the research,
development, testing, manufacture, quality control, approval, labeling, packaging, storage, record-keeping, promotion, advertising, distribution, post-
approval monitoring and reporting, marketing and export and import of drug and biological products. Generally, before a new drug or biologic can be
marketed, considerable data demonstrating its quality, safety and efficacy must be obtained, organized into a format specific for each regulatory authority,
submitted for review and approved by the regulatory authority.
U.S. Drug Development
In the United States, the FDA regulates drugs under the Food, Drug, and Cosmetic Act (FDCA) and biologics under the FDCA and the Public
Health Service Act (PHSA). Both drugs and biologics also are subject to other federal, state and local statutes and regulations. The process of obtaining
regulatory approvals and the subsequent compliance with appropriate federal, state, local and foreign statutes and regulations requires the expenditure of
substantial time and financial resources. Failure to comply with the applicable U.S. requirements at any time during the product development process,
approval process or post-market may subject an applicant to administrative or judicial sanctions. These sanctions could include, among other actions, the
FDA’s refusal to approve pending applications, withdrawal of an approval, a clinical hold, untitled or warning letters, product recalls or market
withdrawals, product seizures, total or partial suspension of production or distribution, injunctions, fines, refusals of government contracts, restitution,
disgorgement and civil or criminal penalties. Any agency or judicial enforcement action could have a material adverse effect on us.
30
Any future product candidates must be approved by the FDA through either a biologics license application (BLA) or new drug application (NDA)
process before they may be legally marketed in the United States. The process generally involves the following:
•
•
•
•
•
•
•
•
•
•
Completion of extensive preclinical studies in accordance with applicable regulations, including studies conducted in accordance with GLP;
Submission to the FDA of an investigational new drug application (IND), which must become effective before human clinical trials may
begin;
Approval by an independent Institutional Review Board (IRB), or ethics committee at each clinical trial site before each trial may be
initiated;
Performance of adequate and well-controlled human clinical trials in accordance with applicable IND regulations, good clinical practice
(GCP), requirements and other clinical trial-related regulations to establish the safety and efficacy of the investigational product for each
proposed indication;
Submission to the FDA of an NDA or BLA;
A determination by the FDA within 60 days of its receipt of an NDA or BLA to accept the filing for review;
Satisfactory completion of a FDA pre-approval inspection of the manufacturing facility or facilities where the drug or biologic will be
produced to assess compliance with cGMP, requirements to assure that the facilities, methods and controls are adequate to preserve the drug
or biologic’s identity, strength, quality, and purity;
Potential FDA audit of the preclinical study and/or clinical trial sites that generated the data in support of the NDA or BLA;
FDA review and approval of the NDA or BLA, including consideration of the views of any FDA advisory committee, prior to any
commercial marketing or sale of the drug or biologic in the United States; and
Compliance with any post-approval requirements, including the potential requirement to implement a Risk Evaluation and Mitigation
Strategy (REMS), and the potential requirement to conduct post-approval studies.
The data required to support an NDA or BLA are generated in two distinct developmental stages: preclinical and clinical. The preclinical and
clinical testing and approval process requires substantial time, effort and financial resources, and we cannot be certain that any approvals for any future
product candidates will be granted on a timely basis, or at all.
The preclinical developmental stage generally involves laboratory evaluations of drug chemistry, formulation and stability, as well as studies to
evaluate toxicity in animals, which support subsequent clinical testing. The sponsor must submit the results of the preclinical studies, together with
manufacturing information, analytical data, any available clinical data or literature and a proposed clinical protocol, to the FDA as part of the IND. An IND
is a request for authorization from the FDA to administer an investigational product to humans, and must become effective before human clinical trials may
begin.
Preclinical studies include laboratory evaluation of product chemistry and formulation, as well as in vitro and animal studies to assess the potential
for adverse events and in some cases to establish a rationale for therapeutic use. The conduct of preclinical studies is subject to federal regulations and
requirements, including GLP regulations for safety/toxicology studies. An IND sponsor must submit the results of the preclinical tests, together with
manufacturing information, analytical data, any available clinical data or literature and plans for clinical studies, among other things, to the FDA as part of
an IND. Some long-term preclinical testing, such as animal tests of reproductive adverse events and carcinogenicity, may continue after the IND is
submitted. An IND automatically becomes effective 30 days after receipt by the FDA, unless before that time the FDA raises concerns or questions related
to one or more proposed clinical trials and places the trial on clinical hold. In such a case, the IND sponsor and the FDA must resolve any outstanding
concerns before the clinical trial can begin. As a result, submission of an IND may not result in the FDA allowing clinical trials to commence.
31
Regulatory requirements for approval of therapies for the treatment of neurodegenerative diseases are evolving. For example, two new agents,
aducanumab and lecanemab, recently received accelerated approval from the FDA based on a surrogate endpoint, the reduction of amyloid beta plaque in
the brain. Under the FDA’s accelerated approval pathway, a surrogate endpoint that is reasonably likely to predict a clinical benefit to patients may serve as
the basis for an accelerated approval, subject to subsequent confirmatory studies. By contrast, the FDA declined to grant accelerated approval for another
product, donanemab, in AD, based on an insufficient number of patients with at least 12 months of drug exposure. FDA also recently granted accelerated
approval for sodium phenylbutyrate/taurursodiol for treatment of ALS, based on efficacy data from a single 24-week Phase 2 study. The FDA advisory
committee that voted in favor of approval was presented with survival data for the drug in that Phase 2 study as well as biomarker data from the drug in a
separate Phase 2 AD study. In addition, a recent publication of disease progression models for genetically inherited forms of FTD, including FTD-GRN,
may help inform the design of clinical trials for such forms of FTD based on more accurate estimations of sample size and the potential use of biomarkers
as surrogate endpoints to reduce sample size. We are evaluating the applicability of these developments to our clinical programs, and based on that
evaluation, we may engage with regulatory authorities to discuss the approval paths for our product candidates.
Clinical Trials
The clinical stage of development involves the administration of the investigational product to healthy volunteers or patients under the supervision
of qualified investigators, generally physicians not employed by or under the trial sponsor’s control, in accordance with GCP requirements, which include
the requirement that all research subjects provide their informed consent for their participation in any clinical trial. Clinical trials are conducted under
protocols detailing, among other things, the objectives of the clinical trial, dosing procedures, subject selection and exclusion criteria and the parameters to
be used to monitor subject safety and assess efficacy. Each protocol, and any subsequent amendments to the protocol, must be submitted to the FDA as part
of the IND. Furthermore, each clinical trial must be reviewed and approved by an IRB for each institution at which the clinical trial will be conducted to
ensure that the risks to individuals participating in the clinical trials are minimized and are reasonable in relation to anticipated benefits. The IRB also
approves the informed consent form that must be provided to each clinical trial subject or his or her legal representative, and must monitor the clinical trial
until completed. There also are requirements governing the reporting of ongoing clinical trials and completed clinical trial results to public registries.
A sponsor who wishes to conduct a clinical trial outside of the United States may, but need not, obtain FDA authorization to conduct the clinical
trial under an IND. If a foreign clinical trial is not conducted under an IND, the sponsor may submit data from the clinical trial to the FDA in support of an
NDA or BLA. The FDA will accept a well-designed and well-conducted foreign clinical trial not conducted under an IND if the trial was conducted in
accordance with GCP requirements and the FDA is able to validate the data through an onsite inspection if deemed necessary.
Clinical trials in the United States generally are conducted in three sequential phases, known as Phase 1, Phase 2, and Phase 3, and may overlap.
•
•
•
Phase 1 clinical trials generally involve a small number of healthy volunteers or disease-affected patients who are initially exposed to a
single dose and then multiple doses of the product candidate. The primary purpose of these clinical trials is to assess the metabolism,
pharmacologic action, tolerability and safety of the drug.
Phase 2 clinical trials involve studies in disease-affected patients to determine the dose required to produce the desired benefits. At the same
time, safety and further pharmacokinetic and pharmacodynamic information is collected, possible adverse effects and safety risks are
identified, and a preliminary evaluation of efficacy is conducted.
Phase 3 clinical trials generally involve a large number of patients at multiple sites and are designed to provide the data necessary to
demonstrate the effectiveness of the product for its intended use, its safety in use and to establish the overall benefit/risk relationship of the
product and provide an adequate basis for product approval. These trials may include comparisons with placebo and/or other comparator
treatments. The duration of treatment is often extended to mimic the actual use of a product during marketing.
32
Post-approval trials, sometimes referred to as Phase 4 clinical trials, may be conducted after initial marketing approval. These trials are used to gain
additional experience from the treatment of patients in the intended therapeutic indication. In certain instances, the FDA may mandate the performance of
Phase 4 clinical trials as a condition of approval of an NDA or BLA.
Progress reports detailing the results of the clinical trials, among other information, must be submitted at least annually to the FDA and written IND
safety reports must be submitted to the FDA and the investigators for serious and unexpected suspected adverse events, findings from other studies
suggesting a significant risk to humans exposed to the drug or biologic, findings from animal or in vitro testing that suggest a significant risk for human
volunteers and any clinically important increase in the rate of a serious suspected adverse reaction over that listed in the protocol or investigator brochure.
Phase 1, Phase 2, and Phase 3 clinical trials may not be completed successfully within any specified period, if at all. The FDA or the sponsor may
suspend or terminate a clinical trial at any time on various grounds, including a finding that the research subjects or patients are being exposed to an
unacceptable health risk. Similarly, an IRB can suspend or terminate approval of a clinical trial at its institution if the clinical trial is not being conducted in
accordance with the IRB’s requirements or if the drug or biologic has been associated with unexpected serious harm to patients. Additionally, some clinical
trials are overseen by an independent group of qualified experts organized by the clinical trial sponsor, known as a data safety monitoring board or
committee. This group provides authorization for whether a trial may move forward at designated checkpoints based on access to certain data from the trial.
Concurrent with clinical trials, companies usually complete additional animal studies and also must develop additional information about the chemistry and
physical characteristics of the drug or biologic as well as finalize a process for manufacturing the product in commercial quantities in accordance with
cGMP requirements. The manufacturing process must be capable of consistently producing quality batches of the product and, among other things,
companies must develop methods for testing the identity, strength, quality, and purity of the final product. Additionally, appropriate packaging must be
selected and tested, and stability studies must be conducted to demonstrate that our product candidates do not undergo unacceptable deterioration over their
shelf life.
As a result of the consequences of the COVID-19 pandemic, the FDA has issued various COVID-19 related guidance documents applicable to
biopharmaceutical manufacturers and clinical trial sponsors. For example, in March 2020, the FDA issued a guidance, which the FDA subsequently
updated, on conducting clinical trials during the pandemic, which describes a number of considerations for sponsors of clinical trials impacted by the
pandemic, including the requirement to include in the clinical trial report contingency measures implemented to manage the clinical trial, any disruption of
the clinical trial as a result of the COVID-19 pandemic, and impact of implemented contingency measures (e.g., participant discontinuation from
investigational product and/or study, alternative procedures used to collect critical safety and/or efficacy data) on the safety and efficacy results reported for
the clinical trial, among others. In 2020 and 2021, the FDA has published a number of industry guidance documents, including updates to previous
guidance, related to Good Manufacturing Practices, remote interactive evaluations of drug manufacturing and bioresearch monitoring facilities, and drug
product manufacturing and supply chain inspections, among others. These and future guidance documents and regulatory requirements, including future
legislation, may require us to develop and implement new policies and procedures, make significant adjustments to our clinical trials, or increase the
amount time and resources needed for regulatory compliance, which may impact our clinical development plans and timelines. The extent to which the
COVID-19 public health emergency impacts our business, including non-clinical studies and clinical trials, will depend on future developments, which are
highly uncertain and cannot be predicted with confidence.
NDA/BLA Review Process
Following completion of the clinical trials, data is analyzed to assess whether the investigational product is safe and effective for the proposed
indicated use or uses. The results of preclinical studies and clinical trials are then submitted to the FDA as part of an NDA or BLA, along with proposed
labeling, chemistry and manufacturing information to ensure product quality and other relevant data. In short, the NDA or BLA is a request for approval to
market the drug or biologic for one or more specified indications and must contain proof of safety and efficacy for a drug or safety, purity, and potency for
a biologic. The application may include both negative and ambiguous results of preclinical studies and clinical trials, as well as positive findings. Data may
come from company-sponsored clinical trials intended to test the safety and efficacy of a product’s use or from a number of alternative sources, including
studies initiated by investigators. To support marketing approval, the data submitted must be sufficient in
33
quality and quantity to establish the safety and efficacy of the investigational product to the satisfaction of FDA. FDA approval of an NDA or BLA must be
obtained before a drug or biologic may be marketed in the United States.
Under the Prescription Drug User Fee Act (PDUFA), as amended, each NDA or BLA must be accompanied by a user fee. FDA adjusts the PDUFA
user fees on an annual basis. According to the FDA’s 2023 fee schedule for prescription drug user fees, which became effective on October 1, 2022, and
will remain in effect through September 30, 2023, the user fee for an application requiring clinical data, such as an NDA or BLA, is approximately $3.2
million. PDUFA also imposes an annual program fee for each marketed human drug or biologic ($369,413 in 2022) and an annual establishment fee on
facilities used to manufacture prescription drugs and biologics. Fee waivers or reductions are available in certain circumstances, including a waiver of the
application fee for the first application filed by a small business. Additionally, no user fees are assessed on NDAs or BLAs for products designated as
orphan drugs, unless the product also includes a non-orphan indication.
The FDA reviews all submitted NDAs and BLAs before it accepts them for filing, and may request additional information rather than accepting the
NDA or BLA for filing. The FDA must make a decision on accepting an NDA or BLA for filing within 60 days of receipt. Once the submission is accepted
for filing, the FDA begins an in-depth review of the NDA or BLA. Under the goals and policies agreed to by the FDA under PDUFA, the FDA has 10
months, from the filing date, in which to complete its initial review of a new molecular-entity NDA or original BLA and respond to the applicant, and six
months from the filing date of a new molecular-entity NDA or original BLA designated for priority review. The FDA does not always meet its PDUFA
goal dates for standard and priority NDAs or BLAs, and the review process is often extended by FDA requests for additional information or clarification.
Before approving an NDA or BLA, the FDA will conduct a pre-approval inspection of the manufacturing facilities for the new product to determine
whether they comply with cGMP requirements. The FDA will not approve the product unless it determines that the manufacturing processes and facilities
are in compliance with cGMP requirements and adequate to assure consistent production of the product within required specifications. The FDA also may
audit data from clinical trials to ensure compliance with GCP requirements. Additionally, the FDA may refer applications for novel drug products or drug
products which present difficult questions of safety or efficacy to an advisory committee, typically a panel that includes clinicians and other experts, for
review, evaluation and a recommendation as to whether the application should be approved and under what conditions, if any. The FDA is not bound by
recommendations of an advisory committee, but it considers such recommendations when making decisions on approval. The FDA likely will reanalyze
the clinical trial data, which could result in extensive discussions between the FDA and the applicant during the review process. After the FDA evaluates an
NDA or BLA, it will issue an approval letter or a Complete Response Letter. An approval letter authorizes commercial marketing of the drug with specific
prescribing information for specific indications. A Complete Response Letter indicates that the review cycle of the application is complete, and the
application will not be approved in its present form. A Complete Response Letter usually describes all of the specific deficiencies in the NDA or BLA
identified by the FDA. The Complete Response Letter may require additional clinical data, additional pivotal Phase 3 clinical trial(s) and/or other
significant and time-consuming requirements related to clinical trials, preclinical studies or manufacturing. If a Complete Response Letter is issued, the
applicant may either resubmit the NDA or BLA, addressing all of the deficiencies identified in the letter, or withdraw the application. Even if such data and
information are submitted, the FDA may decide that the NDA or BLA does not satisfy the criteria for approval. Data obtained from clinical trials are not
always conclusive and the FDA may interpret data differently than we interpret the same data.
Orphan Drugs
Under the Orphan Drug Act, the FDA may grant orphan designation to a drug or biological product intended to treat a rare disease or condition,
which is generally a disease or condition that affects fewer than 200,000 individuals in the United States, or more than 200,000 individuals in the United
States and for which there is no reasonable expectation that the cost of developing and making the product available in the United States for this type of
disease or condition will be recovered from sales of the product.
Orphan drug designation must be requested before submitting an NDA or BLA. After the FDA grants orphan drug designation, the identity of the
therapeutic agent and its potential orphan use are disclosed publicly by the
34
FDA. Orphan drug designation does not convey any advantage in or shorten the duration of the regulatory review and approval process.
If a product that has orphan drug designation subsequently receives the first FDA approval for a particular active ingredient for the disease for which
it has such designation, the product is entitled to orphan drug exclusivity. This means that the FDA may not approve any other NDA or BLA application to
market the same drug or biologic for the same indication for seven years, except in limited circumstances such as a showing of clinical superiority to the
product with orphan exclusivity, if FDA revokes the orphan drug designation, or if FDA finds that the holder of the orphan exclusivity has not assured the
availability of sufficient quantities of the orphan product to meet the needs of patients with the disease or condition for which the drug was designated.
Even though the FDA has approved orphan drug status for latozinemab and AL101 for treatment of FTD, the FDA can still approve other drugs that have a
different active ingredient for use in treating FTD. Furthermore, orphan drug exclusivity does not prevent the FDA from approving another marketing
application for the same drug product for a different indication before the expiration of the orphan exclusivity period. Orphan drug exclusivity also could
block the approval of one of our products for seven years if a competitor obtains approval before we do for the same product, as defined by the FDA, for
the same indication we are seeking approval, or if a product candidate is determined to be contained within the scope of the competitor’s product for the
same indication or disease. If one of our products designated as an orphan drug receives marketing approval for an indication for which it has not been
granted orphan drug designation, it will not have orphan drug exclusivity in that non-orphan indication. Orphan drug status in the European Union has
similar, but not identical, requirements and benefits.
In litigation in 2021, a court disagreed with the FDA’s longstanding position that orphan drug exclusivity only applies to the approved use or
indication within an eligible disease, and not to all uses or indications within the entire designated disease or condition. This appellate court decision
created uncertainty in the application of orphan drug exclusivity. In January 2023, the FDA published a notice in the Federal Register to clarify that while
the agency complies with the applicable court ruling. The FDA intends to continue tying the scope of orphan-drug exclusivity to the uses or indications for
which a drug is approved, which permits other sponsors to obtain approval of a drug for new uses or indications within the same orphan designated disease
or condition that has not yet been approved. It is unclear how future litigation, legislation, agency decisions, and administrative actions will impact the
scope of orphan drug exclusivity.
Expedited Development and Review Programs
The FDA has a fast track program that is intended to expedite or facilitate the process for reviewing new drugs and biologics that meet certain
criteria. Specifically, new drugs and biologics are eligible for fast track designation if they are intended to treat a serious or life-threatening condition and
preclinical or clinical data demonstrate the potential to address unmet medical needs for the condition. Fast track designation applies to both the product
and the specific indication for which it is being studied. The sponsor can request the FDA to designate the product for fast track status any time before
receiving NDA or BLA approval, but ideally no later than the pre-NDA or pre-BLA meeting.
Any product submitted to the FDA for marketing, including under a fast track program, may be eligible for other types of FDA programs intended to
expedite development and review, such as priority review and accelerated approval. Any product is eligible for priority review if it treats a serious or life-
threatening condition and, if approved, would provide a significant improvement in safety and effectiveness compared to available therapies.
A product may also be eligible for accelerated approval, if it treats a serious or life-threatening condition and generally provides a meaningful
advantage over available therapies. In addition, it must demonstrate an effect on a surrogate endpoint that is reasonably likely to predict clinical benefit or
on a clinical endpoint that can be measured earlier than irreversible morbidity or mortality (IMM), which is reasonably likely to predict an effect on IMM
or other clinical benefit. As a condition of approval, the FDA may require that a sponsor of a drug or biologic receiving accelerated approval perform
adequate and well-controlled post-marketing clinical trials. If the FDA concludes that a drug or biologic shown to be effective can be safely used only if
distribution or use is restricted, it may require such post-marketing restrictions as it deems necessary to assure safe use of the product.
Additionally, a drug or biologic may be eligible for designation as a breakthrough therapy if the product is intended, alone or in combination with
one or more other drugs or biologics, to treat a serious or life-threatening condition and preliminary clinical evidence indicates that the product may
demonstrate substantial improvement over currently approved therapies on one or more clinically significant endpoints. The benefits of breakthrough
35
therapy designation include the same benefits as fast track designation, plus intensive guidance from the FDA to ensure an efficient drug development
program. Fast track designation, priority review, accelerated approval and breakthrough therapy designation do not change the standards for approval, but
may expedite the development or approval process.
Abbreviated Licensure Pathway of Biological Products as Biosimilar or Interchangeable
The Patient Protection and Affordable Care Act, or ACA, signed into law in 2010, includes the BPCIA, which created an abbreviated approval
pathway for biological products shown to be highly similar to an FDA-licensed reference biological product. The BPCIA attempts to minimize duplicative
testing, and thereby lower development costs and increase patient access to affordable treatments. An application for licensure of a biosimilar product must
include information demonstrating biosimilarity based upon the following, unless the FDA determines otherwise:
•
•
•
•
o
o
o
o
analytical studies demonstrating that the proposed biosimilar product is highly similar to the approved product notwithstanding minor
differences in clinically inactive components;
animal studies (including the assessment of toxicity); and
a clinical trial or trials (including the assessment of immunogenicity and pharmacokinetic or pharmacodynamic) sufficient to demonstrate
safety, purity, and potency in one or more conditions for which the reference product is licensed and intended to be used.
In addition, an application must include information demonstrating that:
the proposed biosimilar product and reference product utilize the same mechanism of action for the condition(s) of use prescribed,
recommended or suggested in the proposed labeling, but only to the extent the mechanism(s) of action are known for the reference
product;
the condition or conditions of use prescribed, recommended or suggested in the labeling for the proposed biosimilar product have been
previously approved for the reference product;
the route of administration, the dosage form and the strength of the proposed biosimilar product are the same as those for the reference
product; and
the facility in which the biological product is manufactured, processed, packed or held meets standards designed to assure that the
biological product continues to be safe, pure, and potent.
Biosimilarity means that the biological product is highly similar to the reference product notwithstanding minor differences in clinically inactive
components; and that there are no clinically meaningful differences between the biological product and the reference product in terms of the safety, purity,
and potency of the product. In addition, the law provides for a designation of “interchangeability” between the reference and biosimilar products, whereby
the biosimilar may be substituted for the reference product without the intervention of the healthcare provider who prescribed the reference product. The
higher standard of interchangeability must be demonstrated by information sufficient to show that:
•
•
•
the proposed product is biosimilar to the reference product;
the proposed product is expected to produce the same clinical result as the reference product in any given patient; and
for a product that is administered more than once to an individual, the risk to the patient in terms of safety or diminished efficacy of
alternating or switching between the biosimilar and the reference product is no greater than the risk of using the reference product without
such alternation or switch.
FDA approval is required before a biosimilar may be marketed in the United States. However, complexities associated with the large and intricate
structures of biological products and the process by which such products are manufactured pose significant hurdles to the FDA’s implementation of the law
that are still being worked out by the FDA. For example, the FDA has discretion over the kind and amount of scientific evidence—laboratory, preclinical
and/or clinical—required to demonstrate biosimilarity to a licensed biological product.
The FDA intends to consider the totality of the evidence provided by a sponsor to support a demonstration of biosimilarity and recommends that
sponsors use a stepwise approach in the development of their biosimilar
36
products. Biosimilar product applications thus may not be required to duplicate the entirety of preclinical and clinical testing used to establish the
underlying safety and effectiveness of the reference product. However, the FDA may refuse to approve a biosimilar application if there is insufficient
information to show that the active ingredients are the same or to demonstrate that any impurities or differences in active ingredients do not affect the
safety, purity, or potency of the biosimilar product. In addition, as with BLAs, biosimilar product applications will not be approved unless the product is
manufactured in facilities designed to assure and preserve the biological product’s safety, purity, and potency.
The submission of a biosimilar application does not guarantee that the FDA will accept the application for filing and review, as the FDA may refuse
to accept applications that it finds are insufficiently complete. The FDA will treat a biosimilar application or supplement as incomplete if, among other
reasons, any applicable user fees assessed under the Biosimilar User Fee Act of 2012 have not been paid. In addition, the FDA may accept an application
for filing but deny approval on the basis that the sponsor has not demonstrated biosimilarity, in which case the sponsor may choose to conduct further
analytical, preclinical or clinical studies and submit a BLA for licensure as a new biological product.
The timing of final FDA approval of a biosimilar for commercial distribution depends on a variety of factors, including whether the manufacturer of
the branded product is entitled to one or more statutory exclusivity periods, during which time the FDA is prohibited from approving any products that are
biosimilar to the branded product. The FDA cannot approve a biosimilar application for 12 years from the date of first licensure of the reference product.
Additionally, a biosimilar product sponsor may not submit an application for four years from the date of first licensure of the reference product. A reference
product may also be entitled to exclusivity under other statutory provisions. For example, a reference product designated for a rare disease or condition (an
orphan drug) may be entitled to seven years of exclusivity, in which case no product that is biosimilar to the reference product may be approved until either
the end of the twelve-year period provided under the biosimilarity statute or the end of the seven-year orphan drug exclusivity period, whichever occurs
later. In certain circumstances, a regulatory exclusivity period can extend beyond the life of a patent, and thus block biosimilarity applications from being
approved on or after the patent expiration date. In addition, the FDA may under certain circumstances extend the exclusivity period for the reference
product by an additional six months if the FDA requests, and the manufacturer undertakes, studies on the effect of its product in children, a so-called
pediatric extension.
The first biological product determined to be interchangeable with a branded product for any condition of use is also entitled to a period of
exclusivity, during which time the FDA may not determine that another product is interchangeable with the reference product for any condition of use. This
exclusivity period extends until the earlier of: one year after the first commercial marketing of the first interchangeable product; 18 months after resolution
of a patent infringement against the applicant that submitted the application for the first interchangeable product, based on a final court decision regarding
all of the patents in the litigation or dismissal of the litigation with or without prejudice; 42 months after approval of the first interchangeable product, if a
patent infringement suit against the applicant that submitted the application for the first interchangeable product is still ongoing; or 18 months after
approval of the first interchangeable product if the applicant that submitted the application for the first interchangeable product has not been sued.
Post-Approval Requirements
Following approval of a new product, the manufacturer and the approved product are subject to continuing regulation by the FDA, including, among
other things, monitoring and record-keeping requirements, requirements to report adverse experiences and comply with promotion and advertising
requirements, which include restrictions on promoting drugs for unapproved uses or patient populations, known as “off-label use”, and limitations on
industry-sponsored scientific and educational activities. Although physicians may prescribe legally available drugs for off-label uses, manufacturers may
not market or promote such uses. Prescription drug promotional materials must be submitted to the FDA in conjunction with their first use. Further, if there
are any modifications to the drug or biologic, including changes in indications, labeling or manufacturing processes or facilities, the applicant may be
required to submit and obtain FDA approval of a new NDA/BLA or NDA/BLA supplement, which may require the development of additional data or
preclinical studies and clinical trials.
The FDA may also place other conditions on approvals including the requirement for REMS, to assure the safe use of the product. A REMS could
include medication guides, physician communication plans or elements to assure safe use, such as restricted distribution methods, patient registries and
other risk minimization tools. Any of
37
these limitations on approval or marketing could restrict the commercial promotion, distribution, prescription or dispensing of products. Product approvals
may be withdrawn for non-compliance with regulatory standards or if problems occur following initial marketing.
The FDA may withdraw approval if compliance with regulatory requirements and standards is not maintained or if problems occur after the product
reaches the market. Later discovery of previously unknown problems with a product, including adverse events of unanticipated severity or frequency, or
with manufacturing processes, or failure to comply with regulatory requirements, may result in revisions to the approved labeling to add new safety
information; imposition of post-market studies or clinical studies to assess new safety risks or imposition of distribution restrictions or other restrictions
under a REMS program. Other potential consequences include, among other things:
•
•
•
•
•
•
restrictions on the marketing or manufacturing of the product, complete withdrawal of the product from the market, or product recalls;
fines, warning letters, or holds on post-approval clinical studies;
refusal of the FDA to approve pending applications or supplements to approved applications;
applications, or suspension or revocation of product license approvals;
product seizure or detention, or refusal to permit the import or export of products; or
injunctions or the imposition of civil or criminal penalties.
The FDA strictly regulates marketing, labeling, advertising and promotion of products that are placed on the market. Drugs and biologics may be
promoted only for the approved indications and in accordance with the provisions of the approved label. The FDA and other agencies actively enforce the
laws and regulations prohibiting the promotion of off-label uses, and a company that is found to have improperly promoted off-label uses may be subject to
significant liability.
Other U.S. Regulatory Matters
Manufacturing, sales, promotion and other activities following product approval are also subject to regulation by numerous regulatory authorities in
the United States in addition to the FDA, including the Centers for Medicare and Medicaid Services, other divisions of the Department of Health and
Human Services, the Department of Justice, the Drug Enforcement Administration, the Consumer Product Safety Commission, the Federal Trade
Commission, the Occupational Safety & Health Administration, the Environmental Protection Agency, and state and local governments.
For example, in the United States, sales, marketing and scientific and educational programs also must comply with state and federal fraud and abuse
laws. These laws include the federal Anti-Kickback Statute, which makes it illegal for any person, including a prescription drug manufacturer (or a party
acting on its behalf), to knowingly and willfully solicit, receive, offer or pay any remuneration that is intended to induce or reward referrals, including the
purchase, recommendation, order or prescription of a particular drug, for which payment may be made under a federal healthcare program, such as
Medicare or Medicaid. Violations of this law are punishable by up to five years in prison, criminal fines, administrative civil money penalties and exclusion
from participation in federal healthcare programs. Moreover, the ACA provides that the government may assert that a claim including items or services
resulting from a violation of the federal Anti-Kickback Statute constitutes a false or fraudulent claim for purposes of the False Claims Act.
Pricing and rebate programs must comply with the Medicaid rebate requirements of the U.S. Omnibus Budget Reconciliation Act of 1990 and more
recent requirements in the ACA. If products are made available to authorized users of the Federal Supply Schedule of the General Services Administration,
additional laws and requirements apply. Products must meet applicable child-resistant packaging requirements under the U.S. Poison Prevention Packaging
Act. Manufacturing, sales, promotion and other activities also are potentially subject to federal and state consumer protection and unfair competition laws.
The distribution of biologic and pharmaceutical products is subject to additional requirements and regulations, including extensive record-keeping,
licensing, storage and security requirements intended to prevent the unauthorized sale of pharmaceutical products.
38
The failure to comply with any of these laws or regulatory requirements subjects firms to possible legal or regulatory action. Depending on the
circumstances, failure to meet applicable regulatory requirements can result in criminal prosecution, fines or other penalties, injunctions, requests for recall,
seizure of products, total or partial suspension of production, denial or withdrawal of product approvals or refusal to allow a firm to enter into supply
contracts, including government contracts. Any action against us for violation of these laws, even if we successfully defend against it, could cause us to
incur significant legal expenses and divert our management’s attention from the operation of our business. Prohibitions or restrictions on sales or
withdrawal of future products marketed by us could materially affect our business in an adverse way.
Changes in regulations, statutes or the interpretation of existing regulations could impact our business in the future by requiring, for example:
changes to our manufacturing arrangements; additions or modifications to product labeling; the recall or discontinuation of our products; or additional
record-keeping requirements. If any such changes were to be imposed, they could adversely affect the operation of our business.
U.S. Patent-Term Restoration and Marketing Exclusivity
Depending upon the timing, duration and specifics of FDA approval of any future product candidates, some of our U.S. patents may be eligible for
limited patent term extension under the Hatch-Waxman Act. The Hatch-Waxman Act permits restoration of the patent term of up to five years as
compensation for patent term lost during product development and FDA regulatory review process. Patent-term restoration, however, cannot extend the
remaining term of a patent beyond a total of 14 years from the product’s approval date. The patent-term restoration period is generally one-half the time
between the effective date of an IND and the submission date of an NDA or BLA plus the time between the submission date of an NDA or BLA and the
approval of that application, except that the review period is reduced by any time during which the applicant failed to exercise due diligence. Only one
patent applicable to an approved drug is eligible for the extension and the application for the extension must be submitted prior to the expiration of the
patent. The United States Patent and Trademark Office (USPTO), in consultation with the FDA, reviews and approves the application for any patent term
extension or restoration. In the future, we may apply for restoration of patent term for our currently owned or licensed patents to add patent life beyond its
current expiration date, depending on the expected length of the clinical trials and other factors involved in the filing of the relevant NDA or BLA.
Market exclusivity provisions under the FDCA also can delay the submission or the approval of certain applications. The FDCA provides a five-
year period of non-patent marketing exclusivity within the United States to the first applicant to gain approval of a NDA for a new chemical entity. A drug
is a new chemical entity if the FDA has not previously approved any other new drug containing the same active moiety, which is the molecule or ion
responsible for the action of the drug substance. During the exclusivity period, the FDA may not accept for review an abbreviated new drug application
(ANDA), or a 505(b)(2) NDA submitted by another company for another version of such drug where the applicant does not own or have a legal right of
reference to all the data required for approval. However, an application may be submitted after four years if it contains a certification of patent invalidity or
non-infringement. The FDCA also provides three years of marketing exclusivity for a NDA, 505(b)(2) NDA or supplement to an existing NDA if new
clinical investigations, other than bioavailability studies, that were conducted or sponsored by the applicant are deemed by the FDA to be essential to the
approval of the application, for example, new indications, dosages or strengths of an existing drug. This three-year exclusivity covers only the conditions of
use associated with the new clinical investigations and does not prohibit the FDA from approving ANDAs for drugs containing the original active agent.
Five-year and three-year exclusivity will not delay the submission or approval of a full NDA. However, an applicant submitting a full NDA would be
required to conduct or obtain a right of reference to all of the preclinical studies and adequate and well-controlled clinical trials necessary to demonstrate
safety and effectiveness.
A reference biological product is granted 12 years of data exclusivity from the time of first licensure of the product, and the FDA will not accept an
application for a biosimilar or interchangeable product based on the reference biological product until four years after the date of first licensure of the
reference product. “First licensure” typically means the initial date the particular product at issue was licensed in the United States. Date of first licensure
does not include the date of licensure of (and a new period of exclusivity is not available for) a biological product if the licensure is for a supplement for the
biological product or for a subsequent application by the same sponsor or manufacturer of the biological product (or licensor, predecessor in interest or
other related entity) for a change (not including a modification to the structure of the biological product) that results in a new indication, route of
administration, dosing schedule, dosage form, delivery system, delivery device or strength or for
39
a modification to the structure of the biological product that does not result in a change in safety, purity, or potency. Therefore, one must determine whether
a new product includes a modification to the structure of a previously licensed product that results in a change in safety, purity, or potency to assess whether
the licensure of the new product is a first licensure that triggers its own period of exclusivity. Whether a subsequent application, if approved, warrants
exclusivity as the “first licensure” of a biological product is determined on a case-by-case basis with data submitted by the sponsor.
European Union Drug Development
Similar to the United States, the various phases of preclinical and clinical research in the European Union are subject to significant regulatory
controls. Although the EU Clinical Trials Directive 2001/20/EC has sought to harmonize the EU clinical trials regulatory framework, setting out common
rules for the control and authorization of clinical trials in the EU, the EU Member States have transposed and applied the provisions of the Directive
differently. This has led to significant variations in the member state regimes. Under the current regime, before a clinical trial can be initiated it must be
approved in each of the EU countries where the trial is to be conducted by two distinct bodies: the National Competent Authority (NCA), and one or more
Ethics Committees (ECs). Under the current regime all suspected unexpected serious adverse reactions to the investigated drug that occur during the
clinical trial have to be reported to the NCA and ECs of the Member State where they occurred.
The Clinical Trials Regulation EU No 536/2014, which replaced the Clinical Trials Directive and entered into application on January 31, 2022, is
intended to simplify the current rules for clinical trial authorization and is aimed at harmonizing and streamlining clinical-trial authorization, simplifying
adverse-event reporting procedures, improving the supervision of clinical trials and increasing their transparency.
European Union Drug Review and Approval
In the European Economic Area (EEA), which is comprised of the 27 Member States of the European Union (including Norway and excluding
Croatia), Iceland and Liechtenstein, medicinal products can only be commercialized after obtaining a Marketing Authorization (MA). There are two types
of marketing authorizations.
•
•
The Community MA is issued by the European Commission through the Centralized Procedure, based on the opinion of the Committee for
Medicinal Products for Human Use (CHMP), of the European Medicines Agency (EMA), and is valid throughout the entire territory of the
EEA. The Centralized Procedure is mandatory for certain types of products, such as biotechnology medicinal products, orphan medicinal
products, advanced-therapy medicines such as gene-therapy, somatic cell-therapy or tissue-engineered medicines and medicinal products
containing a new active substance indicated for the treatment of HIV, AIDS, cancer, neurodegenerative disorders, diabetes, auto-immune
and other immune dysfunctions and viral diseases. The Centralized Procedure is optional for products containing a new active substance not
yet authorized in the EEA, or for products that constitute a significant therapeutic, scientific or technical innovation or which are in the
interest of public health in the EU.
National MAs, which are issued by the competent authorities of the Member States of the EEA and only cover their respective territory, are
available for products not falling within the mandatory scope of the Centralized Procedure. Where a product has already been authorized
for marketing in a Member State of the EEA, this National MA can be recognized in another Member States through the Mutual
Recognition Procedure. If the product has not received a National MA in any Member State at the time of application, it can be approved
simultaneously in various Member States through the Decentralized Procedure. Under the Decentralized Procedure an identical dossier is
submitted to the competent authorities of each of the Member States in which the MA is sought, one of which is selected by the applicant as
the Reference Member State (RMS). The competent authority of the RMS prepares a draft assessment report, a draft summary of the
product characteristics (SPC), and a draft of the labeling and package leaflet, which are sent to the other Member States (referred to as the
Member States Concerned) for their approval. If the Member States Concerned raise no objections, based on a potential serious risk to
public health, to the assessment, SPC, labeling or packaging proposed by the RMS, the product is subsequently granted a national MA in all
the Member States (i.e., in the RMS and the Member States Concerned).
40
Under the above described procedures, before granting the MA, the EMA or the competent authorities of the Member States of the EEA make an
assessment of the risk-benefit balance of the product on the basis of scientific criteria concerning its quality, safety and efficacy.
Coverage and Reimbursement
Sales of our products will depend, in part, on the extent to which our products will be covered by third-party payors, such as government health
programs, commercial insurance, and managed healthcare organizations. In the United States, no uniform policy of coverage and reimbursement for drug
or biological products exists. Accordingly, decisions regarding the extent of coverage and amount of reimbursement to be provided for any of our products
will be made on a payor-by-payor basis. As a result, the coverage determination process is often a time-consuming and costly process that will require us to
provide scientific and clinical support for the use of our products to each payor separately, with no assurance that coverage and adequate reimbursement
will be obtained.
The United States government, state legislatures, and foreign governments have shown significant interest in implementing cost containment
programs to limit the growth of government-paid healthcare costs, including price-controls, restrictions on reimbursement, and requirements for
substitution of generic products for branded prescription drugs. For example, the ACA contains provisions that may reduce the profitability of drug
products through increased rebates for drugs reimbursed by Medicaid programs, extension of Medicaid rebates to Medicaid managed care plans, mandatory
discounts for certain Medicare Part D beneficiaries and annual fees based on pharmaceutical companies’ share of sales to federal health care programs.
Adoption of general controls and measures, coupled with the tightening of restrictive policies in jurisdictions with existing controls and measures, could
limit payments for pharmaceutical drugs.
The Medicaid Drug Rebate Program requires pharmaceutical manufacturers to enter into and have in effect a national rebate agreement with the
Secretary of the Department of Health and Human Services as a condition for states to receive federal matching funds for the manufacturer’s outpatient
drugs furnished to Medicaid patients. The ACA made several changes to the Medicaid Drug Rebate Program, including increasing pharmaceutical
manufacturers’ rebate liability by raising the minimum basic Medicaid rebate on most branded prescription drugs from 15.1% of average manufacturer
price (AMP), to 23.1% of AMP and adding a new rebate calculation for “line extensions” (i.e., new formulations, such as extended release formulations) of
solid oral dosage forms of branded products, as well as potentially impacting their rebate liability by modifying the statutory definition of AMP. The ACA
also expanded the universe of Medicaid utilization subject to drug rebates by requiring pharmaceutical manufacturers to pay rebates on Medicaid managed
care utilization and by enlarging the population potentially eligible for Medicaid drug benefits. The Centers for Medicare and Medicaid Services have
proposed to expand Medicaid rebate liability to the territories of the United States as well.
The Medicare Prescription Drug, Improvement, and Modernization Act of 2003 (MMA) established the Medicare Part D program to provide a
voluntary prescription drug benefit to Medicare beneficiaries. Under Part D, Medicare beneficiaries may enroll in prescription drug plans offered by private
entities that provide coverage of outpatient prescription drugs. Unlike Medicare Part A and B, Part D coverage is not standardized. While all Medicare drug
plans must give at least a standard level of coverage set by Medicare, Part D prescription drug plan sponsors are not required to pay for all covered Part D
drugs, and each drug plan can develop its own drug formulary that identifies which drugs it will cover and at what tier or level. However, Part D
prescription drug formularies must include drugs within each therapeutic category and class of covered Part D drugs, though not necessarily all the drugs in
each category or class. Any formulary used by a Part D prescription drug plan must be developed and reviewed by a pharmacy and therapeutic committee.
Government payment for some of the costs of prescription drugs may increase demand for products for which we receive marketing approval. However,
any negotiated prices for our products covered by a Part D prescription drug plan likely will be lower than the prices we might otherwise obtain. Moreover,
while the MMA applies only to drug benefits for Medicare beneficiaries, private payors often follow Medicare coverage policy and payment limitations in
setting their own payment rates. Any reduction in payment that results from the MMA may result in a similar reduction in payments from non-
governmental payors.
For a drug product to receive federal reimbursement under the Medicaid or Medicare Part B programs or to be sold directly to U.S. government
agencies, the manufacturer must extend discounts to entities eligible to participate in the 340B drug pricing program. The required 340B discount on a
given product is calculated based on the AMP and Medicaid rebate amounts reported by the manufacturer.
41
There has been increasing legislative and enforcement interest in the United States with respect to specialty drug pricing practices, including U.S.
Congressional inquiries and proposed federal and state legislation designed to, among other things, bring more transparency to drug pricing, reduce the cost
of prescription drugs under Medicare, review the relationship between pricing and manufacturer patient programs, and reform government program
reimbursement methodologies for drugs. At the federal level, under the Trump administration, HHS and CMS issued various rules that were expected to
impact, among others, price reductions from pharmaceutical manufacturers to plan sponsors under Part D, fee arrangements between pharmacy benefit
managers and manufacturers, manufacturer price reporting requirements under the Medicaid Drug Rebate Program, including regulations that affect
manufacturer-sponsored patient assistance programs subject to pharmacy benefit manager accumulator programs and Best Price reporting related to certain
value-based purchasing arrangements. Multiple lawsuits have been brought against the HHS challenging various aspects of these new rules. The Biden
administration and HHS have delayed the implementation or published rules rescinding some of these Trump-era policies.
Under the American Rescue Plan Act of 2021, effective January 1, 2024, the statutory cap on Medicaid Drug Rebate Program rebates that
manufacturers pay to state Medicaid programs will be eliminated. Elimination of this cap may require pharmaceutical manufacturers to pay more in rebates
than they receive on the sale of approved products, which could have a material impact on our business. Further, Congress is considering legislation that, if
passed, could have significant impact on prices of prescription drugs covered by Medicare, including limitations on drug price increases and allowing
Medicare to negotiate pricing for certain covered drugs. The implementation of cost containment measures or other healthcare reforms may prevent us from
being able to generate revenue, attain profitability, or commercialize our product candidates if approved.
Further, many states have proposed or enacted legislation that seeks to indirectly or directly regulate pharmaceutical drug pricing, such as by
requiring biopharmaceutical manufacturers to publicly report proprietary pricing information or to place a maximum price ceiling on pharmaceutical
products purchased by state agencies. For example, a number of states are considering or have recently enacted state drug price transparency and reporting
laws that could substantially increase our compliance burdens and expose us to greater liability under such state laws once we begin commercialization
after obtaining regulatory approval for any of our products candidates. Such initiatives and legislation may affect the prices we may obtain for any of our
product candidates for which we may obtain regulatory approval or the demand for any such product candidate, if approved.
As noted above, the marketability of any products for which we receive regulatory approval for commercial sale may suffer if the government and
third-party payors fail to provide adequate coverage and reimbursement. An increasing emphasis on cost containment measures in the United States has
increased and we expect will continue to increase the pressure on pharmaceutical pricing. Coverage policies and third-party reimbursement rates may
change at any time. Even if favorable coverage and reimbursement status is attained for one or more products for which we receive regulatory approval,
less favorable coverage policies and reimbursement rates may be implemented in the future.
In addition, in most foreign countries, the proposed pricing for a drug must be approved before it may be lawfully marketed. The requirements
governing drug pricing and reimbursement vary widely from country to country. For example, the European Union provides options for its member states
to restrict the range of medicinal products for which their national health insurance systems provide reimbursement and to control the prices of medicinal
products for human use. A member state may approve a specific price for the medicinal product or it may instead adopt a system of direct or indirect
controls on the profitability of the company placing the medicinal product on the market. There can be no assurance that any country that has price controls
or reimbursement limitations for pharmaceutical products will allow favorable reimbursement and pricing arrangements for any of our products.
Historically, products launched in the European Union do not follow price structures of the United States and generally prices tend to be significantly
lower.

As of December 31, 2022, we had 273 full-time employees, over 78% of whom were engaged in research and development activities. None of our
employees are represented by a labor union or covered under a collective bargaining agreement.
Our human capital resources objectives include, as applicable, identifying, recruiting, retaining, incentivizing, and integrating our existing and new
employees, advisors, and consultants. The principal purposes of our equity and cash incentive plans are to attract, retain and reward personnel through the
granting of stock-based and cash-based compensation awards, in order to increase stockholder value and the success of our company by motivating such
individuals to perform to the best of their abilities and achieve our objectives. Over the last several years, the employment market in the United States has
been subject to a competitive hiring and compensation environment, which in turn, has led to certain employee attrition.
In response to the COVID-19 pandemic and subsequent variants, we focused our health and safety efforts on protecting our employees and their
families. We implemented changes that we determined were in the best interest of our employees and the communities in which we operate, and which are
aligned with guidance from the Centers for Disease Control and Prevention and in compliance with applicable state and local regulations. This includes
having some of our employees work from home, while implementing additional safety measures for employees continuing critical on-site work.

Item 1A. Risk Factors.
Investing in our common stock involves a high degree of risk. You should carefully consider the risks described below, as well as the other
information in this Annual Report on Form 10-K, including our financial statements and the related notes and the section titled “Management’s Discussion
and Analysis of Financial Condition and Results of Operations,” and in our other public filings, in evaluating our business. The occurrence of any of the
events or developments described below could harm our business, financial condition, results of operations, and growth prospects. In such an event, the
market price of our common stock could decline, and you may lose all or part of your investment. Additional risks and uncertainties not presently known to
us or that we currently deem immaterial also may impair our business operations and the market price of our common stock.
Summary of Risk Factors
Our business is subject to numerous risks and uncertainties that you should consider before investing in our company, as more fully described below. The
principal factors and uncertainties that make investing in our company risky include, among others:
• We are in the clinical stages of drug development and have a limited operating history and no products approved for commercial sale, which may
make it difficult to evaluate our current business and predict our future success and viability.
• We have incurred significant net losses in each year since our inception and anticipate that we will continue to incur net losses for the foreseeable
future.
•
Drug development is a highly uncertain undertaking and involves a substantial degree of risk.
• We will need to obtain substantial additional financing to complete the development and any commercialization of our product candidates, and a
failure to obtain this necessary capital when needed on acceptable terms, or at all, could force us to delay, limit, reduce, or terminate our
commercialization efforts, product development, or other operations.
•
•
Due to the significant resources required for the development of our programs, and depending on our ability to access capital, we must prioritize
development of certain product candidates. Moreover, we may expend our limited resources on programs that do not yield a successful product
candidate or fail to capitalize on product candidates or indications that may be more profitable or for which there is a greater likelihood of
success.
Research and development of biopharmaceutical products is inherently risky, and our business is heavily dependent on the successful
development of our product candidates, which are in preclinical and clinical development, so we cannot give any assurance that any of our
product candidates will receive regulatory, including marketing, approval, which is necessary before they can be commercialized.
• We may not be successful in our efforts to continue to create a pipeline of product candidates from our research and drug discovery platform or
to develop commercially successful products. If we fail to successfully identify and develop additional product candidates from our research and
drug discovery platform, our commercial opportunity may be limited.
• We may not be successful in our efforts to carry out our obligations under our collaborations for our product development and research
programs; for instance, without limitation, failure to complete in a timely manner or at all our contractual obligations to GSK and AbbVie.
• We may not be successful in our efforts to expand indications for approved product candidates.
• We have concentrated a substantial portion of our research and development efforts on the treatment of neurodegenerative diseases, a field that
has seen both limited success in drug development and evolving standards for regulatory approval. Further, our product candidates are based on
new approaches and novel technology, and we must identify and develop new biomarkers that are signs of a disease or condition and that can
measure the impact of our product candidates on disease progression, which makes it difficult to predict the time and cost of product candidate
development and subsequently obtaining regulatory approval.
45
• We may encounter substantial delays in our clinical trials, or may not be able to conduct or complete our clinical trials on the timelines we
expect, if at all.
•
Our clinical trials may reveal significant adverse events, toxicities, or other side effects and may fail to demonstrate substantial evidence of the
safety and efficacy of our product candidates, which would prevent, delay, or limit the scope of regulatory approval and commercialization.
• We are highly dependent on our key personnel, and if we are not successful in attracting, motivating, and retaining highly qualified personnel, we
may not be able to successfully implement our business strategy.
•
•
Our operations and financial results could continue to be adversely impacted by the COVID-19 pandemic, including the effects of subsequent
variants, in the United States and the rest of the world, including potential supply chain issues and concerns.
The market price of our common stock may continue to experience volatility or decline, which could result in substantial losses for investors and
could negatively impact our ability to conduct additional fundraising in the public markets.
Risks Related to Our Business, Financial Condition, and Capital Requirements
We are in various stages of drug development and have a limited operating history and no products approved for commercial sale, which may make it
difficult to evaluate our current business and predict our future success and viability.
We are a clinical stage biopharmaceutical company with a limited operating history, focused primarily on developing therapeutics for
neurodegenerative diseases, including FTD, Alzheimer’s disease, Parkinson’s disease, and ALS, as well as oncology therapeutics that focus on innate
immune biology. We commenced operations in May 2013. To date, we have financed our operations primarily through the sale of equity securities and
upfront payments received in connection with our collaboration arrangements with AbbVie and GSK. We have no products approved for commercial sale
and have not generated any revenue from product sales. Drug development is a highly uncertain undertaking and involves a substantial degree of risk. We
are in Phase 2 and Phase 3 clinical trials for one product candidate, latozinemab, are in Phase 2 clinical trial for one product candidate, AL002, and we have
completed a Phase 1 clinical trial for AL101. We decided to close the Phase 1 clinical trial for our AL044 product candidate based on initial PK and
tolerability data. In addition, AbbVie decided to terminate the CD33 collaboration program, after AbbVie and Alector collaboratively reviewed next steps
for AL003, the asset being developed under that program, and concluded that further development of AL003 was not warranted. To date, we have not
completed a pivotal clinical trial, obtained marketing approval for any product candidates, manufactured a commercial scale product, or arranged for a third
party to do so on our behalf, or conducted sales and marketing activities necessary for successful product commercialization. Our limited operating history
as a company makes any assessment of our future success and viability subject to significant uncertainty.
We will encounter risks and difficulties frequently experienced by clinical-stage biopharmaceutical companies in rapidly evolving fields, and we
have not yet demonstrated an ability to successfully overcome such risks and difficulties. If we do not address these risks and difficulties successfully, our
business will suffer.
We have incurred significant net losses in each year since our inception and anticipate that we will continue to incur net losses for the foreseeable
future.
We have incurred net losses in almost every reporting period since our inception. We incurred net losses of $133.3 million, $36.3 million, and
$190.2 million for the years ended December 31, 2022, 2021, and 2020, respectively. As of December 31, 2022, we had an accumulated deficit of $579.7
million.
We have invested significant financial resources in research and development activities, including for our preclinical and clinical product candidates.
We do not expect to generate revenue from product sales for several years, if at all. The revenue we currently generate from our collaboration arrangements
with AbbVie and GSK is variable and limited in amount. For our collaborations with AbbVie and GSK, we recognize collaboration revenue by measuring
the progress towards complete satisfaction of the performance of obligation measured as the program costs are incurred. The amount of our future net
losses will depend, in part, on the level of our future expenditures and revenue. Moreover, our net losses may fluctuate significantly from quarter to quarter
and year to year, such that a period-to-period comparison of our results of operations may not be a good indication of our future performance.
46
On July 1, 2021, we entered into an agreement with GSK to collaborate on the global development and commercialization of progranulin-elevating
monoclonal antibodies, including latozinemab and AL101. Under the terms of the GSK Agreement, we received $700 million in upfront payments, of
which $500 million was received in August 2021 and $200 million was received in January 2022. In addition, we will be eligible to receive up to an
additional $1.5 billion in clinical development, regulatory, and commercial launch-related milestone payments for latozinemab and AL101.
Developing our product candidates is expensive, and we expect to continue to spend substantial amounts as we fund our early-stage research
projects and continue to advance our programs through preclinical and clinical development. Even if we are successful in developing our product
candidates, obtaining regulatory approvals and launching and commercializing any product candidate will require substantial additional funding.
We expect to continue to incur significant expenses and increasingly higher operating losses for the foreseeable future. We anticipate that our
expenses will increase substantially if and as we:
•
•
•
•
•
•
•
•
•
•
•
•
•
•
•
•
•
continue our research and discovery activities;
advance our research and drug discovery platform, including our target, patient, and biomarker selections;
progress our current and any future product candidates through preclinical and clinical development;
initiate and conduct additional preclinical, clinical, or other studies for our product candidates;
work with our contract development and manufacturing organizations (CDMOs) to scale up the manufacturing processes for our product
candidates or, in the future, establish and operate a manufacturing facility;
change or add contract manufacturers or suppliers;
seek regulatory approvals and marketing authorizations for our product candidates;
establish sales, marketing, and distribution infrastructure to commercialize any products for which we obtain approval;
make milestone, royalty, or other payments due under any license or collaboration agreements;
take steps to seek protection of our intellectual property and defend our intellectual property against challenges from third parties;
obtain, maintain, protect, and enforce our intellectual property portfolio, including intellectual property obtained through license and
collaboration agreements;
attract, hire, and retain qualified personnel, especially in light of a competitive hiring and compensation environment;
provide additional internal infrastructure to support our continued research and development operations and any planned commercialization
efforts in the future;
implement additional internal systems and infrastructure related to cybersecurity;
meet the requirements and demands of being a public company;
withstand periods of rising rates of inflation; and
defend against any product liability claims or other lawsuits related to our products.
Our prior losses and expected future losses have had and will continue to have an adverse effect on our stockholders’ equity and working capital. In
any particular quarter or quarters, our operating results could be below the expectations of securities analysts or investors, which could cause our stock
price to decline.
Drug development is a highly uncertain undertaking and involves a substantial degree of risk.
We have no products approved for commercial sale. To obtain revenues from the sales of our product candidates that are significant or large enough
to achieve profitability, we must succeed, either alone or with third
47
parties, in developing, obtaining regulatory approval for, manufacturing, and marketing therapies with significant commercial success. Our ability to
generate revenue and achieve profitability depends on many factors, including:
•
•
•
•
•
•
•
•
•
•
•
•
•
•
completing research and preclinical and clinical development of our product candidates;
addressing impacts on our clinical trials resulting from factors related to the effects of the COVID-19 pandemic and subsequent variants;
obtaining regulatory approvals and marketing authorizations for product candidates for which we successfully complete clinical
development and clinical trials;
developing a sustainable and scalable manufacturing process for our product candidates, as well as establishing and maintaining
commercially viable supply relationships with third parties that can provide adequate products and services to support clinical activities and
commercial demand of our product candidates;
identifying, assessing, acquiring, and/or developing new product candidates;
negotiating favorable terms in any collaboration, licensing, or other arrangements into which we may enter;
launching and successfully commercializing product candidates for which we obtain regulatory and marketing approval, either by
collaborating with a partner or, if launched independently, by establishing a sales, marketing, and distribution infrastructure;
obtaining and maintaining an adequate price for our product candidates, both in the United States and in foreign countries where our
products are commercialized;
obtaining adequate reimbursement for our product candidates from payors;
obtaining market acceptance of our product candidates as viable treatment options;
addressing any competing technological and market developments;
receiving milestones and other payments under our current and any future collaboration arrangements;
maintaining, protecting, expanding, and enforcing our portfolio of intellectual property rights, including patents, trade secrets, and know-
how; and
attracting, hiring, and retaining qualified personnel, especially in light of a recent very competitive compensation environment.
To date, clinical development of two of our product candidates has been terminated. AbbVie decided to terminate the CD33 collaboration program,
after AbbVie and Alector collaboratively reviewed next steps for AL003, the asset being developed under that program, and concluded that further
development of AL003 was not warranted. Additionally, we decided to close the Phase 1 clinical trial for our AL044 product candidate based on initial PK
and tolerability data. Because of the numerous risks and uncertainties associated with drug development, we are unable to predict the timing or amount of
our expenses, or when we will be able to generate any meaningful revenue or achieve or maintain profitability, if ever. In addition, our expenses could
increase beyond our current expectations if we are required by the FDA or foreign regulatory agencies, to perform studies in addition to those that we
currently anticipate, or if there are any delays in any of our or our current or future collaborators’ clinical trials or the development of any of our product
candidates. Even if one or more of our product candidates is approved for commercial sale, we anticipate incurring significant costs associated with
launching and commercializing any approved product candidate and ongoing compliance efforts.
We will need to obtain substantial additional financing to complete the development and any commercialization of our product candidates, and a
failure to obtain this necessary capital when needed on acceptable terms, or at all, could force us to delay, limit, reduce, or terminate our
commercialization efforts, product development, or other operations.
Our operations have required substantial amounts of cash since inception, and we expect our expenses to increase significantly in the foreseeable
future. To date, we have financed our operations primarily through the sale of equity securities and upfront payments received in connection with our
collaboration arrangements with AbbVie
48
and GSK. Developing our product candidates and conducting clinical trials for the treatment of neurodegenerative diseases, including FTD, Alzheimer’s
disease, ALS, and Parkinson’s disease, and in oncology, will require substantial amounts of capital. We will also require a significant amount of capital for
the further development of our product candidates, and if any of such product candidates are approved, to commercialize any approved products.
As of December 31, 2022, we had cash, cash equivalents, and marketable securities of $712.9 million. Based on our current operating plan, we
believe that our existing cash, cash equivalents, and marketable securities, will be sufficient to fund our projected operations through 2025. Our estimate as
to how long we expect our existing cash, cash equivalents, and marketable securities to be available to fund our operations is based on assumptions that
may be proved inaccurate, and we could use our available capital resources sooner than we currently expect. In addition, changing circumstances, including
periods of a rising rate of inflation, may cause us to increase our spending significantly faster than we currently anticipate, and we may need to spend more
money than currently expected because of circumstances beyond our control. We may need to raise additional funds sooner than we anticipate if we choose
to expand more rapidly than we presently anticipate.
Global markets recently have experienced volatility and instability in connection with macroeconomic downturns stemming from increased
inflation, supply chain and other economic impacts of the COVID-19 pandemic and geopolitical events, including the Russian invasion of Ukraine, among
other matters. In addition, the public market for and stock prices of biotechnology companies have experienced a significant downturn over the last few
years. Our ability to raise money in the public markets may be severely impacted for the foreseeable future due to these factors. Additional capital may not
be available when we need it, on terms acceptable to us or at all. If adequate capital is not available to us on a timely basis, we may be required to
significantly delay, scale back, or discontinue our research and development programs or the commercialization of any product candidates, if approved, or
be unable to continue or expand our operations, or otherwise capitalize on our business opportunities, as desired, which could materially affect our
business, financial condition, results of operations, and growth prospects and cause the price of our common stock to decline.
To the extent that we raise additional capital through the sale of equity or convertible debt securities, the ownership interest of our stockholders will
be diluted, and the terms of these securities may include liquidation or other preferences that adversely affect your rights as a common stockholder. Debt
financing, if available, may be unfavorable terms, including interest rates and may involve agreements that include covenants limiting or restricting our
ability to take specific actions, such as incurring additional debt, making capital expenditures, or declaring dividends. If we raise additional funds through
collaborations, strategic alliances, or licensing arrangements with pharmaceutical partners, we may have to relinquish valuable rights to our technologies,
future revenue streams, research programs, or product candidates, or grant licenses on terms that may not be favorable to us.
Due to the significant resources required for the development of our product candidates, and depending on our ability to access capital, we must
prioritize development of certain product candidates. Moreover, we may expend our limited resources on programs that do not yield a successful
product candidate or fail to capitalize on product candidates or indications that may be more profitable or for which there is a greater likelihood of
success.
We have identified over 100 immune system targets. Three of our product candidates, latozinemab, AL002, and AL101, are in clinical development,
and we continue to develop our research pipeline. The development of one of our product candidates, AL003, was terminated in June 2022. Together, the
development of these programs and product candidates requires significant capital investment. Due to the significant resources required for the
development of our programs and product candidates, we must focus our programs and product candidates on specific diseases and disease pathways and
decide which product candidates to pursue and advance and the amount of resources to allocate to each. Our drug development strategy is to clinically test
and seek regulatory approval for our product candidates in indications in which we believe there is the most evidence that we will be able to quickly
generate proof-of-concept data. We then intend to expand to clinical testing and seek regulatory approvals in other neurodegenerative indications based on
genetic and mechanistic overlap with the primary indication.
However, even if our product candidates are able to gain regulatory approval in one indication, there is no guarantee that we will be able to obtain
approval in other indications, and we may expend significant resources in seeking such approvals. In addition, we may focus resources on pursuing
indications outside of neurodegeneration based on the same genetic and mechanistic rationale we utilize in determining on which of our discovery
programs to focus. Our decisions concerning the allocation of research, development, collaboration, management, and
49
financial resources toward particular product candidates or therapeutic areas may not lead to the development of any viable commercial product and may
divert resources away from better opportunities. For example, Innovent will not be continuing development of AL008, and we intend to re-acquire the
rights we granted to Innovent for the development and commercialization of AL008. Innovent submitted an IND with the Chinese regulatory authorities,
and Alector is in the process of obtaining relevant materials and information from Innovent. Alector plans to evaluate data and documentation from that
IND application to potentially support an IND submission in the U.S. Similarly, our potential decisions to delay, terminate, or collaborate with third parties
in respect of certain programs may subsequently also prove to be suboptimal and could cause us to miss valuable opportunities. If we make incorrect
determinations regarding the viability or market potential of any of our programs or product candidates or misread trends in the biopharmaceutical industry,
in particular for neurodegenerative diseases, such events could have a material adverse effect on our business, financial condition, and results of operations.
As a result, we may fail to capitalize on viable commercial products or profitable market opportunities, be required to forego or delay pursuit of
opportunities with other product candidates or other diseases and disease pathways that may later prove to have greater commercial potential than those we
choose to pursue, or relinquish valuable rights to such product candidates through collaboration, licensing, or other royalty arrangements in cases in which
it would have been advantageous for us to invest additional resources to retain sole development and commercialization rights. Our reliance on genetic
screening and use of biomarkers to align patient risk profiles with targeted intervention may eventually require us to develop and use companion
diagnostics, which could impact product development costs and timelines depending on the specific diagnostic and any applicable regulatory requirements
that would need to be met to enable its use.
Risks Related to the Discovery, Development, and Commercialization of Our Product Candidates
Research and development of biopharmaceutical products is inherently risky. Our business is heavily dependent on the successful development of our
product candidates, which are in various stages of preclinical and clinical development. We cannot give any assurance that any of our product
candidates will receive regulatory, including marketing, approval, which is necessary before they can be commercialized.
We are in the clinical stages of development of many of the product candidates currently in our programs. To date, we have invested substantially in
our efforts and financial resources to identify, procure intellectual property for, and develop our programs and product candidates, and provide general and
administrative support for these operations. Our future success is dependent on our ability to successfully develop, obtain regulatory approval for, and then
successfully commercialize our product candidates, and we may fail to do so for many reasons, including the following:
•
•
•
•
•
•
•
•
•
our product candidates may not successfully complete preclinical studies or clinical trials;
a product candidate may on further study be shown to have harmful side effects or other characteristics that indicate it is unlikely to be
effective or otherwise does not meet applicable regulatory criteria;
our competitors may develop therapeutics that render our product candidates obsolete or less attractive;
the product candidates that we develop may not be sufficiently covered by intellectual property for which we hold exclusive rights;
the product candidates that we develop may be covered by third parties’ patents or other intellectual property or exclusive rights;
the market for a product candidate may change so that the continued development of that product candidate is no longer reasonable or
commercially attractive;
a product candidate may not be capable of being produced in sufficient quantities for development or commercialization at an acceptable
cost, or at all;
if a product candidate obtains regulatory approval, we may be unable to establish sales and marketing capabilities, or successfully market
such approved product candidate, to gain market acceptance; and
a product candidate may not be accepted as safe and effective by patients, the medical community or third-party payors, if applicable.
50
If any of these events occur, we may be forced to abandon our development efforts for a program or programs, which would have a material adverse
effect on our business and could potentially cause us to cease operations. For example, after completing the Phase 1 trial for AL003 and reviewing the
collaboration program with us, AbbVie decided to terminate the CD33 collaboration program, under which AL003 was being developed.
We may not be successful in our efforts to further develop our current product candidates. We are not permitted to market or promote any of our
product candidates before we receive regulatory approval from the FDA or comparable foreign regulatory authorities, and we may never receive such
regulatory approval for any of our product candidates. Most of our product candidates are in the early stages of development and all will require significant
additional clinical development, management of preclinical, clinical, and manufacturing activities, regulatory approval, adequate manufacturing supply, a
commercial organization, and significant marketing efforts before we generate any revenue from product sales, if at all.
We have never completed a clinical development program. We are in Phase 2 and Phase 3 clinical trials for one product candidate, latozinemab, are
in Phase 2 clinical development for one product candidate, AL002, and we have completed a Phase 1 clinical trial for AL101. Further, we cannot be certain
that any of our product candidates will be successful in clinical trials. For any product candidates we have advanced into clinical trials, we may terminate
such trials or the clinical program prior to their completion.
If any of our product candidates successfully complete clinical trials, we generally plan to seek regulatory approval to market our product candidates
in the United States, the European Union, and in additional foreign countries where we believe there is a viable commercial opportunity. We have never
commenced, compiled or submitted an application seeking regulatory approval to market any product candidate. We may never receive regulatory approval
to market any product candidates even if such product candidates successfully complete clinical trials, which would adversely affect our viability. To obtain
regulatory approval in countries outside the United States, we must comply with numerous and varying regulatory requirements of such other countries
regarding safety, efficacy, manufacturing and controls, clinical trials, commercial sales, pricing, and distribution of our product candidates. We may also
rely on our collaborators or partners to conduct the required activities to support an application for regulatory approval, and to seek approval, for one or
more of our product candidates. We cannot be sure that our collaborators or partners will conduct these activities or do so within the timeframe we desire.
Even if we (or our collaborators or partners) are successful in obtaining approval in one jurisdiction, we cannot ensure that we will obtain approval in any
other jurisdictions. If we are unable to obtain approval for our product candidates in multiple jurisdictions, our business, financial condition, results of
operations, and our growth prospects could be negatively affected.
Even if we receive regulatory approval to market any of our product candidates, whether for the treatment of neurodegenerative diseases or other
diseases, we cannot be assured that any such product candidate will be successfully commercialized, widely accepted in the marketplace or more effective
than other commercially available alternatives.
Investment in biopharmaceutical product development involves significant risk that any product candidate will fail to demonstrate adequate efficacy
or an acceptable safety profile, gain regulatory approval, and become commercially viable. We cannot provide any assurance that we will be able to
successfully advance any of our product candidates through the development process or, if approved, successfully commercialize any of our product
candidates.
We may not be successful in our efforts to continue to create a pipeline of product candidates from our research and drug discovery platform or to
develop commercially successful products. If we fail to successfully identify and develop additional product candidates from our research and drug
discovery platform, our commercial opportunity may be limited.
One of our strategies is to identify and pursue clinical development of additional product candidates. Identifying, developing, obtaining regulatory
approval, and commercializing additional product candidates for the treatment of neurodegenerative and other diseases will require substantial additional
funding and is prone to the risks of failure inherent in drug development. We cannot provide any assurance that we will be able to successfully identify or
acquire additional product candidates, advance any of these additional product candidates through the development process, successfully commercialize
any such additional product candidates, if approved, or assemble sufficient resources to identify, acquire, develop, or, if approved, commercialize additional
product candidates. If we
51
are unable to successfully identify, acquire, develop, and commercialize additional product candidates, our commercial opportunity may be limited.
We may not be successful in our efforts to obtain approval for additional or expanded indications for our approved product candidates.
Our drug development strategy is to clinically test and seek regulatory approval for our product candidates in indications in which we believe there
is the most evidence that we will be able to quickly generate proof-of-concept data. We then intend to expand to clinical testing and seek regulatory
approvals in other neurodegenerative indications based on genetic and mechanistic overlap with the primary indication. Conducting clinical trials for
additional indications for our product candidates requires substantial technical, financial, and human capital resources and is prone to the risks of failure
inherent in drug development. We cannot provide any assurance that we will be successful in our effort to obtain regulatory approval for our product
candidates for additional indications even if we obtain approval for an initial indication.
We do not have any products approved for commercial sale and have not generated any revenue from product sales.
We have concentrated a substantial portion of our research and development efforts on the treatment of neurodegenerative diseases, a field that has
seen limited success in drug development. Further, our product candidates are based on new approaches and novel technology, and we must identify
and develop new biomarkers that are signs of a disease or condition and that can measure impact on disease progression of our product candidates,
which makes it difficult to predict the time and cost of product candidate development and subsequently obtaining regulatory approval.
We have focused a substantial portion of our research and development efforts on addressing neurodegenerative diseases. Collectively, efforts by
biopharmaceutical companies in the field of neurodegenerative diseases have seen limited success in drug development. There are limited currently
approved therapeutic options available for patients with FTD, Alzheimer’s disease, Parkinson’s disease, ALS, and other neurodegenerative diseases. Our
future success is highly dependent on the successful development of our product candidates for treating neurodegenerative diseases. Developing product
candidates and, if approved, commercializing our products for treatment of neurodegenerative diseases subjects us to a number of challenges, including
obtaining disease modifying activity and efficacious dose in target tissue and obtaining regulatory approval from the FDA and other regulatory authorities
who have only a limited set of precedents to rely on.
Our approach to the treatment of neurodegenerative diseases aims to identify and select targets enriched in microglia and other myeloid immune
cells which are genetically associated with neurodegenerative diseases. We identify and develop product candidates that are designed to cross the blood
brain barrier in sufficient quantity and potency to enable efficacious dosing in the brain and engage the intended target, and we must be able to identify and
develop biomarkers and biomarker assays that can accurately identify signs of a disease or condition, assist us in selecting the right patient population, and
demonstrate target engagement, pathway engagement, and measure the impact on disease progression of our product candidates. This strategy may not
prove to be successful. We cannot be sure that our approach will yield satisfactory therapeutic products that are safe and effective, scalable, or profitable.
We may encounter substantial delays in our clinical trials or may not be able to conduct or complete our clinical trials on the timelines we expect, if at
all.
Clinical testing is expensive, time consuming, and subject to uncertainty. We cannot guarantee that any clinical trials will be conducted as planned or
completed on schedule, if at all. We cannot be sure that submission of an IND or a clinical trial application (CTA) will result in the FDA or EMA, as
applicable, allowing clinical trials to begin in a timely manner, if at all. Moreover, even if these trials begin, issues may arise that could suspend or
terminate such clinical trials. A failure of one or more clinical trials can occur at any stage of testing, and our future clinical trials may not be successful.
Events that may prevent successful or timely initiation or completion of clinical trials include:
•
inability to generate sufficient preclinical, toxicology, or other in vivo or in vitro data to support the initiation or continuation of clinical
trials;
52
•
•
•
•
•
•
•
•
•
•
•
•
•
•
•
•
delays in confirming target engagement, patient selection, or other relevant biomarkers to be utilized in preclinical and clinical product
candidate development;
delays in reaching a consensus with regulatory agencies on study design;
delays in reaching agreement on acceptable terms with prospective contract research organizations (CROs) and clinical trial sites, the terms
of which can be subject to extensive negotiation and may vary significantly among different CROs and clinical trial sites;
delays in identifying, recruiting, and training suitable clinical investigators;
delays in obtaining required IRB/EC approval at each clinical trial site;
imposition of delays to clinical trials, including as a result of temporary or permanent clinical hold by regulatory agencies for a number of
reasons (see for example our discussions of ARIA in other risks described in this “Risk Factors” section), including:
•
•
•
•
•
after review of an IND or amendment, CTA or amendment, or equivalent application or amendment;
as a result of a new safety finding that presents unreasonable risk to clinical trial participants;
as a result of modifications to clinical trial protocols or related documentation;
a negative finding from an inspection of our clinical trial operations or study sites; or
the finding that the investigational protocol or plan is clearly deficient to meet its stated objectives;
delays in identifying, recruiting, and enrolling suitable patients to participate in our clinical trials, and delays caused by patients
withdrawing from clinical trials, or failing to return for post-treatment follow-up;
difficulty collaborating with patient groups and investigators;
failure by our CROs, other third parties, or us to adhere to clinical trial requirements;
failure to perform in accordance with the FDA’s or any other regulatory authority’s current good clinical practices (cGCPs) requirements, or
applicable EMA or other regulatory guidelines in other countries;
occurrence of adverse events associated with the product candidate that are viewed to outweigh its potential benefits;
changes in regulatory requirements and guidance that require amending or submitting new clinical protocols;
changes in the standard of care on which a clinical development plan was based, which may require new or additional trials;
the cost of clinical trials of our product candidates being greater than we anticipate;
clinical trials of our product candidates producing negative or inconclusive results, which may result in our deciding, or regulators requiring
us, to conduct additional clinical trials or abandon product development programs; and
delays in manufacturing, testing, releasing, validating, or importing/exporting sufficient stable quantities of our product candidates for use
in clinical trials or the inability to do any of the foregoing.
Any inability to successfully initiate or complete clinical trials could result in additional costs to us or impair our ability to generate revenue. In
addition, if we make manufacturing or formulation changes to our product candidates, we may be required to or we may elect to conduct additional studies
to bridge our modified product candidates to earlier versions. Clinical trial delays could also shorten any periods during which our products have patent
protection and may allow our competitors to bring products to market before we do, which could impair our ability to successfully commercialize our
product candidates and may harm our business and results of operations.
53
For example, we had been developing AL003 with AbbVie to treat patients with Alzheimer’s disease but on June 30, 2022, AbbVie provided written notice
to us formalizing the decision to terminate the CD33 collaboration program, under which AL003 was being developed. Additionally, Innovent will not be
continuing development of AL008, and we intend to re-acquire the rights we granted to Innovent for the development and commercialization of AL008.
Innovent submitted an IND with the Chinese regulatory authorities, and Alector is in the process of obtaining relevant materials and information from
Innovent. Alector plans to evaluate data and documentation from that IND application to potentially support an IND submission in the U.S. Furthermore,
we decided to close the Phase 1 clinical trial for our AL044 product candidate based on initial PK and tolerability data.
We could also encounter delays if a clinical trial is suspended or terminated by us, by the data safety monitoring board for such trial or by the FDA,
EMA, or any other regulatory authority, or if the IRBs of the institutions in which such trials are being conducted suspend or terminate the participation of
their clinical investigators and sites subject to their review. Such authorities may suspend or terminate a clinical trial due to a number of factors, including
failure to conduct the clinical trial in accordance with regulatory requirements or our clinical protocols, inspection of the clinical trial operations or trial site
by the FDA, EMA, or other regulatory authorities resulting in the imposition of a clinical hold, unforeseen safety issues or adverse side effects, failure to
demonstrate a benefit from using a product candidate, changes in governmental regulations or administrative actions, lack of adequate funding to continue
the clinical trial, impacts of the COVID-19 pandemic and subsequent variants.
We may in the future advance product candidates into clinical trials and terminate such trials prior to their completion, which could adversely affect
our business.
Delays in the completion of any clinical trial of our product candidates will increase our costs, slow down our product candidate development and
approval process and delay, or potentially jeopardize our ability to commence product sales and generate revenue. In addition, many of the factors that
cause, or lead to, a delay in the commencement or completion of clinical trials may also ultimately lead to the denial of regulatory approval of our product
candidates.
We may encounter difficulties enrolling patients in our clinical trials, and our clinical development activities could thereby be delayed or otherwise
adversely affected.
The timely completion of clinical trials in accordance with their protocols depends, among other things, on our ability to enroll a sufficient number
of patients who remain in the trial until its conclusion. We continue to pursue measures to enroll our Phase 3 INFRONT-3 and Phase 2 INVOKE-2 trials.
For example, we are opening additional clinical trial sites and expanding recruitment efforts to enroll the INFRONT-3 trial. However, we may experience
difficulties in patient enrollment in our clinical trials for a variety of reasons, including:
•
•
•
•
•
•
•
•
•
the size and nature of the patient population;
the patient eligibility criteria defined in the protocol, including biomarker-driven identification and/or certain highly-specific criteria related
to stage of disease progression, which may limit the patient populations eligible for our clinical trials to a greater extent than competing
clinical trials for the same indication that do not have biomarker-driven patient eligibility criteria;
the size of the study population required for analysis of the trial’s primary endpoints;
the proximity of patients to a trial site;
the design of the trial;
our ability to recruit clinical trial investigators with the appropriate competencies and experience;
delays in enrolling patients in our clinical trials caused by the effects of the COVID-19 pandemic and subsequent variants;
competing clinical trials for similar therapies or targeting patient populations meeting our patient eligibility criteria;
clinicians’ and patients’ perceptions as to the potential advantages and side effects of the product candidate being studied in relation to other
available therapies and product candidates;
54
•
•
our ability to obtain and maintain patient consents; and
the risk that patients enrolled in clinical trials will not complete such trials or that we may not be able to collect data from such patients for
any reason.
Enrollment of patients in our clinical trials and maintaining patients in our ongoing clinical trials have been, and may continue to be, delayed or
limited due to the effects of the COVID-19 pandemic and subsequent variants. In addition, if additional COVID-19 concerns or restrictions arise, including
as a result of any new COVID-19 variants, patients may not be able or willing to visit clinical trial sites for dosing or data collection purposes due to
additional limitations on travel new physical distancing imposed or recommended by federal or state governments or patients’ reluctance to visit the
clinical trial sites during the pandemic. While the impact of the COVID-19 pandemic is lessening, the effects resulting from the COVID-19 pandemic and
subsequent variants could continue to delay or prevent the anticipated readouts from our clinical trials.
Our clinical trials may reveal significant adverse events, toxicities, or other side effects and may fail to demonstrate substantial evidence of the safety
and efficacy of our product candidates, which would prevent, delay, or limit the scope of regulatory approval and commercialization.
Before obtaining regulatory approvals for the commercial sale of any of our product candidates, we must demonstrate through lengthy, complex, and
expensive preclinical studies and clinical trials that our product candidates are both safe and effective for use in each target indication. For those product
candidates that are subject to regulation as biological drug products, we will need to demonstrate that they are safe, pure, and potent for use in their target
indications. Each product candidate must demonstrate an adequate risk versus benefit profile in its intended patient population and for its intended use.
Clinical testing is expensive and can take many years to complete, and its outcome is inherently uncertain. Failure can occur at any time during the
clinical trial process. The results of preclinical studies of our product candidates may not be predictive of the results of early-stage or later-stage clinical
trials, and results of early clinical trials of our product candidates may not be predictive of the results of later-stage clinical trials. The results of clinical
trials in healthy volunteers or one set of patients or disease indications may not be predictive of those obtained in another. In some instances, there can be
significant variability in safety or efficacy results between different clinical trials of the same product candidate due to numerous factors, including changes
in trial procedures set forth in protocols, differences in the size and type of the patient populations, changes in and adherence to the dosing regimen, and
other clinical trial protocol elements and the rate of dropout among clinical trial participants. Open-label or long-term extension studies may also extend the
timing and cost of a clinical program substantially. Product candidates in later stages of clinical trials may fail to show the desired safety and efficacy
profile despite having progressed through preclinical studies and initial clinical trials. A number of companies in the biopharmaceutical industry have
suffered significant setbacks in advanced clinical trials due to lack of efficacy or unacceptable safety issues, notwithstanding promising results in earlier
trials. This is particularly true in neurodegenerative diseases, where failure rates historically have been higher than in many other disease areas. Most
product candidates that begin clinical trials are never approved by regulatory authorities for commercialization.
For example, in our ongoing INVOKE-2 Phase 2 clinical trial in Alzheimer’s disease, cases of ARIA have been observed. ARIA are MRI findings
suggestive of vasogenic edema or hemosiderin deposits. The incidence of ARIA has been shown to increase in AD patients with the administration of
certain Alzheimer's disease therapeutics, namely anti-β-amyloid antibodies. In our INVOKE-2 Phase 2 clinical trial, most ARIA cases were asymptomatic
and non-serious. However, a small number of ARIA-related serious adverse events occurred almost exclusively in patients with the APOE e4/e4 genotype,
as previously reported. To mitigate risks associated with ARIA, we voluntarily discontinued dosing and enrollment of APOE e4/e4 participants in our
INVOKE-2 Phase 2 clinical trial. Following these changes, a small number of ARIA-related serious adverse events occurred in patients who are non-
homozygous for the APOE e4 allele. We continue to implement earlier MRI monitoring, consistent with recently published guidelines for ARIA
monitoring and management. We are conducting this study under the guidance of an IDMC, which is allowed to review unblinded data and to make trial
recommendations.
We have limited experience in designing clinical trials and may be unable to design and execute a clinical trial to support marketing approval. We
cannot be certain that our current clinical trials or any other future clinical trials will be successful. Additionally, any safety concerns observed in any one
of our clinical trials in our targeted indications could limit the prospects for regulatory approval of our product candidates in those and other indications,
which could have a material adverse effect on our business, financial condition, and results of operations.
55
In addition, even if such clinical trials are successfully completed, we cannot guarantee that the FDA or foreign regulatory authorities will interpret
the results as we do, and more trials could be required before we submit our product candidates for approval. To the extent that the results of the trials are
not satisfactory to the FDA or foreign regulatory authorities for support of a marketing application, we may be required to expend
significant resources, which may not be available to us, to conduct additional trials in support of potential approval of our product candidates. Even if
regulatory approval is secured for any of our product candidates, the terms of such approval may limit the scope and use of our product candidates, which
may also limit its commercial potential.
Our operations and financial results could be adversely impacted by the effects of the COVID-19 pandemic and subsequent variants in the United
States and the rest of the world.
The COVID-19 pandemic, including recent variants that spread throughout the world, has adversely impacted global commercial activity. While the
impact of the COVID-19 pandemic is lessening, such events have contributed to significant volatility and instability in financial markets, including a rising
rate of inflation. The COVID-19 pandemic and government responses created disruption in global supply chains and adversely impacted many industries.
The pandemic could have a continued material adverse impact on economic and market conditions, including a continued rapid increase in inflation rates,
and lead to a further extended period of global economic slowdown. We continue to monitor the impact of the COVID-19 pandemic closely. The extent to
which the COVID-19 pandemic will impact our operations or financial results is uncertain.
The COVID-19 pandemic and government measures taken in response have also had a significant impact, both direct and indirect, on businesses
and commerce, such as worker shortages; supply chain issues and disruptions; facilities and production suspensions; increases in inflation rates; and spikes
in demand for certain goods and services, such as medical services and supplies. While the extent of the impact of the effects of the COVID-19 pandemic
on our business and financial results is uncertain, a continued and prolonged public health crisis such as the COVID-19 pandemic could have a material
adverse effect on our business, financial condition and results of operations. If as a result of the global COVID-19 pandemic and any new variants that may
later arise, we may experience disruptions, especially supply chain disruptions, that could have severe impacts on our business and clinical trials, such as:
•
•
•
•
•
•
•
•
•
•
•
the size and nature of the patient populations for our clinical trials;
delays or difficulties in recruiting, enrolling, and maintaining patients in our clinical trials;
delays or difficulties in clinical site initiation, including difficulties in recruiting clinical site investigators and clinical site staff;
diversion of healthcare resources away from the conduct of clinical trials, including the diversion of hospitals serving as our clinical trial
sites and hospital staff supporting the conduct of clinical trials;
interruption of key clinical trial activities, such as clinical trial site monitoring, due to new limitations on travel imposed or recommended
by federal or state governments, employers and others;
limitations in resources that would otherwise be focused on the conduct of our business or our clinical trials, including because of sickness
or the desire to avoid contact with large groups of people or as a result of government-imposed “shelter in place” or similar working
restrictions;
delays in receiving approval from local regulatory authorities to initiate our planned clinical trials;
delays in clinical sites receiving the supplies and materials needed to conduct our clinical trials;
interruption in global shipping that may affect the transport of clinical trial materials, such as investigational drug product used in our
clinical trials;
changes in regulations as part of a response to the COVID-19 pandemic which may require us to change the ways in which our clinical
trials are conducted, or to discontinue the clinical trials altogether, or which may result in unexpected costs;
delays in necessary interactions with regulators, IRBs/ECs and other important agencies and contractors due to limitations in employee
resources or forced furlough of government or contractor personnel; and
56
•
refusal of the FDA to accept data from clinical trials in affected geographies outside the United States.
We may be required to develop, implement, and maintain additional clinical trial policies and procedures designed to help protect subjects from
the COVID-19 virus, which may delay our anticipated timelines for clinical studies and regulatory approval and increase our costs for clinical studies. For
example, in March 2020, the FDA issued a guidance, which the FDA subsequently updated, on conducting clinical trials during the pandemic, which
describes a number of considerations for sponsors of clinical trials impacted by the pandemic. In 2020 and 2021, the FDA issued guidance on good
manufacturing practice considerations for responding to COVID-19 infection in employees in drug and biological products manufacturing, remote
interactive evaluations of drug manufacturing and bioresearch monitoring facilities; and manufacturing, supply chain, and drug and biological product
inspections, among others. In light of the spread of COVID-19 variants, the FDA, EMA, and comparable foreign regulators may issue additional guidance
and policies that may materially impact our business and clinical development timelines. Further changes to existing policies and regulations could increase
our compliance costs or delay our clinical plans. To the extent our clinical studies are delayed or data from our clinical studies become compromised due to
COVID-19 related factors, we may be required to expend additional resources to conduct additional studies and/or enroll more participants, which could
adversely affect our business operations and delay regulatory approval.
The COVID-19 pandemic continues to evolve, and the extent to which may impact our business, preclinical studies, and clinical trials will
depend on future developments, which are highly uncertain and cannot be predicted with confidence, such as the duration of the pandemic, travel
restrictions, social distancing in the United States and other countries, business closures or business disruptions, the effectiveness of actions taken in the
United States and other countries to contain and treat the disease, and the possibility of new variants. We may also suffer from any of the foregoing
disruptions if the COVID-19 virus and subsequent variants continue to develop and experience a resurgence in any particular country or region in the
future.
The spread of COVID-19 and its subsequent variants has caused us to modify our business practices including by employing more remote
workers and operating under hybrid work model. In addition, we may take actions as required by government authorities and regulations or that we
determine are in the best interests of our employees, customers, partners, and suppliers. Many of our employees continue to work remotely. Our ability to
perform critical functions could be harmed. We may incur incremental expenses in connection with travel for remote employees, which we will continue to
monitor; such expenses could adversely impact our results of operations.
Additionally, certain third parties with whom we engage, including our collaborators, contract organizations, third party manufacturers, suppliers,
clinical trial sites, regulators and other third parties with whom we conduct business have similarly adjusted their operations and assessed their capacity in
light of the COVID-19 pandemic and the impact of subsequent variants. If these third parties experience shutdowns or business disruptions, our ability to
conduct our business in the manner and on the timelines presently planned could be materially and negatively impacted.
For example, certain of our clinical trial sites experienced clinical trial visit delays, and we are aware that for a period of time, some participants
in our then ongoing trials did not receive scheduled doses or assessments on time. These events could negatively impact the integrity, reliability, or
robustness of the data from our clinical trials. We and our CROs made certain adjustments to the operation of such trials in an effort to ensure the
monitoring and safety of patients and minimize risks to trial integrity during the pandemic in accordance with the guidance issued by the FDA, and we may
be required to make further adjustments in the future due to any resurgence of COVID-19.
To the extent the ongoing COVID-19 pandemic or other disease outbreaks adversely affect our operations and financial results, it may also have
the effect of heightening many of the other risks described in this “Risk Factors” section.
We face significant competition in an environment of rapid technological and scientific change, and there is a possibility that our competitors may
achieve regulatory approval before us or develop therapies that are safer, more advanced, or more effective than ours, which may negatively impact our
ability to successfully market or commercialize any product candidates we may develop and ultimately harm our financial condition.
The development and commercialization of new drug products is highly competitive. Moreover, the neurodegenerative field is characterized by
strong and increasing competition, and a strong emphasis on intellectual property. We may face competition with respect to any of our product candidates
that we seek to develop or commercialize in the future from major pharmaceutical companies, specialty pharmaceutical companies, and
57
biotechnology companies worldwide. Potential competitors also include academic institutions, government agencies, and other public and private research
organizations that conduct research, seek patent protection, and establish collaborative arrangements for research, development, manufacturing, and
commercialization.
There are a number of large pharmaceutical and biotechnology companies that are currently pursuing the development of products for the
treatment of neurodegenerative diseases, including FTD, Alzheimer’s disease, Parkinson's disease, and ALS, as well as for the treatment of cancer. Many of
these current or potential competitors, either alone or with their strategic partners, have significantly greater financial resources and expertise in research
and development, manufacturing, preclinical testing, conducting clinical trials, obtaining regulatory approvals, and marketing approved products than we
do. For example, in January 2023, FDA approved lecanemab, an anti-amyloid beta protofibril antibody for the treatment of Alzeimer’s disease developed
by Eisai Co., Ltd. (Eisai) and Biogen Inc. (Biogen). Eisai has also filed marketing authorization applications in Japan and Europe. Additionally, in July
2022, Biogen announced that the FDA accepted a NDA for tofersen, an drug for ALS associated with mutations in superoxide dismutase 1 (SOD1), and in
September 2022, Amylyx Pharmaceuticals, Inc. announced that the FDA approved RELYVRIO™ (sodium phenylbutyrate and taurursodiol) for the
treatment of adults with ALS. Other competitors are pursuing product candidates that act on the same targets or through comparable mechanisms of action.
Furthermore, mergers and acquisitions in the pharmaceutical and biotechnology industries may result in even more resources being concentrated
among a smaller number of our competitors. Smaller or early-stage companies may also prove to be significant competitors, particularly through
collaborative arrangements with large and established companies. These competitors also compete with us in recruiting and retaining qualified scientific
and management personnel and establishing clinical trial sites and patient enrollment in clinical trials, as well as in acquiring technologies complementary
to, or necessary for, our programs. Our commercial opportunity could be reduced or eliminated if our competitors develop and commercialize products that
are safer, more effective, have fewer or less severe side effects, are more convenient, or are less expensive than any products that we may develop.
Furthermore, currently approved products could be discovered to have application for treatment of neurodegenerative disease indications, which could give
such products significant regulatory and market timing advantages over any of our product candidates. Our competitors also may obtain FDA, EMA, or
other regulatory approval for their products more rapidly than we may obtain approval for ours and may obtain orphan drug exclusivity from the FDA for
indications our product candidates are targeting, which could result in our competitors establishing a strong market position before we are able to enter the
market. Additionally, products or technologies developed by our competitors may render our potential product candidates uneconomical or obsolete, and
we may not be successful in marketing any product candidates we may develop against competitors.
In addition, we could face litigation or other proceedings with respect to the scope, ownership, validity, and/or enforceability of our patents relating
to our competitors’ products and our competitors may allege that our products infringe, misappropriate, or otherwise violate their intellectual property. The
availability of our competitors’ products could limit the demand, and the price we are able to charge, for any products that we may develop and
commercialize.
The manufacture of our product candidates is complex, and we may encounter difficulties in production. If we or any of our third-party manufacturers
encounter such difficulties, or fail to meet rigorously enforced regulatory standards, our ability to provide supply of our product candidates for clinical
trials or our products for patients, if approved, could be delayed or stopped, or we may be unable to maintain a commercially viable cost structure.
The processes involved in manufacturing our product candidates are complex, expensive, highly-regulated, and subject to multiple risks. Further, as
product candidates are developed through preclinical studies to late-stage clinical trials towards approval and commercialization, it is common that various
aspects of the development program, such as manufacturing methods, are altered along the way in an effort to optimize processes and results. Such changes
carry the risk that they will not achieve these intended objectives, and any of these changes could cause our product candidates to perform differently and
affect the results of planned clinical trials or other future clinical trials.
In order to conduct clinical trials of our product candidates, or supply commercial products, if approved, we will need to manufacture them in large
quantities. Our CDMOs may be unable to successfully increase the manufacturing capacity for any of our product candidates in a timely or cost-effective
manner, or at all. In addition, quality issues may arise during scale-up activities. If our CDMOs are unable to successfully scale up the
58
manufacture of our product candidates in sufficient quality and quantity, the development, testing, and clinical trials of that product candidate may be
delayed or become infeasible, and regulatory approval or commercial launch of any resulting product may be delayed or not obtained, which could
significantly harm our business. The same risk would apply to our internal manufacturing facilities, should we in the future decide to build internal
manufacturing capacity. In addition, building internal manufacturing capacity would carry significant risks in terms of being able to plan, design, and
execute on a complex project to build manufacturing facilities in a timely and cost-efficient manner.
In addition, the manufacturing process for any products that we may develop is subject to FDA, EMA, and foreign regulatory authority approval
processes, and continuous oversight, and we will need to contract with manufacturers who can meet all applicable FDA, EMA, and foreign regulatory
authority requirements, including complying with current good manufacturing practices (cGMPs) on an ongoing basis. If we or our third-party
manufacturers are unable to reliably produce products to specifications acceptable to the FDA, EMA, or other regulatory authorities, including recent FDA
guidance on good manufacturing practice considerations for responding to COVID-19 infection in employees in drug and biological products
manufacturing, as well as any future guidance and regulations, we may not obtain or maintain the approvals we need to commercialize such products. Even
if we obtain regulatory approval for any of our product candidates, there is no assurance that either we or our CDMOs will be able to manufacture the
approved product to specifications acceptable to the FDA, EMA, or other regulatory authorities, to produce it in sufficient quantities to meet the
requirements for the potential launch of the product, or to meet potential future demand. Any of these challenges could delay completion of clinical trials,
require bridging clinical trials or the repetition of one or more clinical trials, increase clinical trial costs, delay approval of our product candidates, impair
commercialization efforts, increase our cost of goods, and have an adverse effect on our business, financial condition, results of operations, and growth
prospects.
If, in the future, we are unable to establish sales and marketing capabilities or enter into agreements with third parties to sell and market any product
candidates we may develop, we may not be successful in commercializing those product candidates if and when they are approved.
We do not have a sales or marketing infrastructure and have no experience in the sale, marketing, or distribution of pharmaceutical products. To
achieve commercial success for any approved product for which we retain sales and marketing responsibilities, we must either develop a sales and
marketing organization or outsource these functions to third parties. In the future, we may choose to build a focused sales, marketing, and commercial
support infrastructure to sell, or participate in commercial activities with our collaborators for, some of our product candidates if and when they are
approved.
There are risks involved with both establishing our own commercial capabilities and entering into arrangements with third parties to perform these
services. For example, recruiting and training a sales force or reimbursement specialists is expensive and time consuming and could delay any product
launch. If the commercial launch of a product candidate for which we recruit a sales force and establish marketing and other commercialization capabilities
is delayed or does not occur for any reason, we would have prematurely or unnecessarily incurred these commercialization expenses. This may be costly,
and our investment would be lost if we cannot retain or reposition our commercialization personnel.
Factors that may inhibit our efforts to commercialize any approved product on our own include:
•
•
•
•
•
our inability to recruit and retain adequate numbers of effective sales, marketing, reimbursement, customer service, medical affairs, and
other support personnel;
the inability of sales personnel to obtain access to physicians or persuade adequate numbers of physicians to prescribe any future approved
products;
our inability to negotiate arrangements for formulary access, reimbursement, and other acceptance by payors;
the inability to price our products at a sufficient price point to ensure an adequate and attractive level of profitability; and our ability to
recognize revenue from such prices;
restricted or closed distribution channels that make it difficult to distribute our products to segments of the patient population;
59
•
•
the lack of complementary products to be offered by sales personnel, which may put us at a competitive disadvantage relative to companies
with more extensive product lines; and
unforeseen costs and expenses associated with creating an independent commercialization organization.
If we enter into arrangements with third parties to perform sales, marketing, commercial support, and distribution services, our product revenue or
the profitability of product revenue may be lower than if we were to market and sell any products we may develop ourselves. In addition, we may not be
successful in entering into arrangements with third parties to commercialize our product candidates or may be unable to do so on terms that are favorable to
us. We may have little control over such third parties, and any of them may fail to devote the necessary resources and attention to sell and market our
products effectively. If we do not establish commercialization capabilities successfully, either on our own or in collaboration with third parties, we will not
be successful in commercializing our product candidates if approved.
Even if any product candidates we develop receive marketing approval, they may fail to achieve the degree of market acceptance by physicians,
patients, healthcare payors, and others in the medical community necessary for commercial success.
The commercial success of any of our products will depend upon its degree of market acceptance by physicians, patients, third-party payors, and
others in the medical community. Even if any product candidates we may develop receive marketing approval, they may nonetheless fail to gain sufficient
market acceptance by physicians, patients, healthcare payors, and others in the medical community. The degree of market acceptance of any product
candidates we may develop, if approved for commercial sale, will depend on a number of factors, including:
•
•
•
•
•
•
•
•
•
•
•
•
•
•
the efficacy and safety as demonstrated in clinical trials and published in peer-reviewed journals;
the potential and perceived advantages compared to alternative treatments;
the ability to offer our products for sale at competitive prices;
sufficient third-party coverage or reimbursement;
the ability to offer appropriate patient access programs, such as co-pay assistance;
the extent to which physicians recommend our products to their patients;
convenience and ease of dosing and administration compared to alternative treatments;
the clinical indications for which the product candidate is approved by FDA, EMA, or other regulatory agencies;
product labeling or product insert requirements of the FDA, EMA, or other comparable foreign regulatory authorities, including any
limitations, contraindications, or warnings contained in a product’s approved labeling;
restrictions on how the product is distributed;
the timing of market introduction of competitive products;
publicity concerning our products or competing products and treatments;
the strength of marketing and distribution support; and
the prevalence and severity of any side effects.
If any product candidates we develop do not achieve an adequate level of acceptance, we may not generate significant product revenue, and we may
not become profitable.
60
Any products we commercialize may become subject to unfavorable pricing regulations, third-party reimbursement practices, or healthcare reform
initiatives, which would harm our business.
The regulations that govern marketing approvals, pricing, and reimbursement for new drugs vary widely from country to country. In the United
States, recently enacted or potential future legislation may significantly change the approval requirements in ways that could involve additional costs and
cause delays in obtaining approvals. Some countries require approval of the sale price of a drug before it can be marketed. In many countries, the pricing
review period begins after marketing or product licensing approval is granted. In some foreign markets, prescription pharmaceutical pricing remains subject
to continuing governmental control even after initial approval is granted. As a result, we might obtain marketing approval for a product in a particular
country, but then be subject to price regulations that delay our commercial launch of the product, possibly for lengthy time periods, and negatively impact
the revenue we are able to generate from the sale of the product in that country. Adverse pricing limitations may hinder our ability to recoup our investment
in one or more product candidates, even if any product candidates we may develop obtain marketing approval.
Our ability to successfully commercialize any products that we may develop also will depend in part on the extent to which reimbursement for these
products and related treatments will be available from government health administration authorities, private health insurers, and other organizations.
Government authorities and third-party payors, such as private health insurers and health maintenance organizations, decide which medications they will
pay for and establish reimbursement levels. A primary trend in the U.S. healthcare industry and elsewhere is cost containment. Government authorities and
third-party payors have attempted to control costs by limiting coverage and the amount of reimbursement for particular medications. Government
authorities currently impose mandatory discounts for certain patient groups, such as Medicare, Medicaid, and Veterans Affairs hospitals, and may seek to
increase such discounts at any time. Future regulation may negatively impact the price of our products, if approved. Increasingly, third-party payors are
requiring that drug companies provide them with predetermined discounts from list prices and are challenging the prices charged for medical products. We
cannot be sure that reimbursement will be available for any product candidate that we commercialize and, if reimbursement is available, the level of
reimbursement. Reimbursement may impact the demand for, or the price of, any product candidate for which we obtain marketing approval. In order to get
reimbursement, physicians may need to show that patients have superior treatment outcomes with our products compared to standard of care drugs,
including lower-priced generic versions of standard of care drugs. If reimbursement is not available or is available only to limited levels, we may not be
able to successfully commercialize any product candidate for which we obtain marketing approval. In the United States, no uniform policy of coverage and
reimbursement for products exists among third-party payors and coverage and reimbursement levels for products can differ significantly from payor to
payor. As a result, the coverage determination process is often a time consuming and costly process that may require us to provide scientific and clinical
support for the use of our products to each payor separately, with no assurance that coverage and adequate reimbursement will be applied consistently or
obtained in the first instance.
There may be significant delays in obtaining reimbursement for newly approved drugs, and coverage may be more limited than the purposes for
which the medicine is approved by the FDA, EMA, or other comparable foreign regulatory authorities. Moreover, eligibility for reimbursement does not
imply that any drug will be paid for in all cases or at a rate that covers our costs, including research, development, manufacture, sale, and distribution.
Interim reimbursement levels for new drugs, if applicable, may also not be sufficient to cover our costs and may not be made permanent. Reimbursement
rates may vary according to the use of the drug and the clinical setting in which it is used, may be based on reimbursement levels already set for lower cost
drugs and may be incorporated into existing payments for other services. Net prices for drugs may be reduced by mandatory discounts or rebates required
by government healthcare programs or private payors and by any future relaxation of laws that presently restrict imports of drugs from countries where
they may be sold at lower prices than in the United States. Third-party payors often rely upon Medicare coverage policy and payment limitations in setting
their own reimbursement policies. Our inability to promptly obtain coverage and profitable payment rates from both government-funded and private payors
for any approved products we may develop could have a material adverse effect on our operating results, our ability to raise capital needed to
commercialize product candidates, and our overall financial condition.
Current and future CMS coverage restrictions on classes of drugs that encompass our product candidates, including our candidates for treating
Alzheimer’s disease, could have a material adverse impact on our ability to commercialize our product candidates, if approved, generate revenue and attain
profitability. It is unclear how future CMS coverage decisions and policies will impact our business.
61
Our product candidates for which we intend to seek approval may face biosimilar competition sooner than anticipated.
Even if we are successful in achieving regulatory approval to commercialize a product candidate ahead of our competitors, our product candidates
may face competition from biosimilar products. In the United States, our product candidates are regulated by the FDA as biologic products and we intend
to seek approval for these product candidates pursuant to the BLA pathway. The Biologics Price Competition and Innovation Act of 2009 (BPCIA) created
an abbreviated pathway for the approval of biosimilar and interchangeable biologic products. The abbreviated regulatory pathway establishes legal
authority for the FDA to review and approve biosimilar biologics, including the possible designation of a biosimilar as “interchangeable” based on its
similarity to an existing brand product. Under the BPCIA, an application for a biosimilar product cannot be approved by the FDA until 12 years after the
original branded product was approved under a BLA. The law is complex and is still being interpreted and implemented by the FDA. As a result, its
ultimate impact, implementation, and meaning are subject to uncertainty. While it is uncertain when such processes intended to implement BPCIA may be
fully adopted by the FDA, any such processes could have a material adverse effect on the future commercial prospects for our product candidates.
We believe that any of our product candidates approved as a biologic product under a BLA should qualify for the 12-year period of exclusivity.
However, there is a risk that this exclusivity could be shortened due to Congressional action or otherwise, or that the FDA will not consider our product
candidates to be reference products for competing products, potentially creating the opportunity for competition sooner than anticipated. Moreover, the
extent to which a biosimilar product, once approved, will be substituted for any one of our reference products in a way that is analogous to traditional
generic substitution for non-biologic products is not yet clear, and will depend on a number of marketplace and regulatory factors that are still developing.
In addition, a competitor could decide to forego the biosimilar approval path and submit a full BLA after completing its own preclinical studies and clinical
trials. In such cases, any exclusivity to which we may be eligible under the BPCIA would not prevent the competitor from marketing its product as soon as
it is approved.
In Europe, the European Commission has granted marketing authorizations for several biosimilar products pursuant to a set of general and product
class-specific guidelines for biosimilar approvals issued over the past few years. In Europe, a competitor may reference data supporting approval of an
innovative biological product, but will not be able to get it on the market until 10 years after the time of approval of the innovative product. This 10-year
marketing exclusivity period will be extended to 11 years if, during the first eight of those 10 years, the marketing authorization holder obtains an approval
for one or more new therapeutic indications that bring significant clinical benefits compared with existing therapies. In addition, companies may be
developing biosimilar products in other countries that could compete with our products, if approved.
If competitors are able to obtain marketing approval for biosimilars referencing our product candidates, if approved, such products may become
subject to competition from such biosimilars, with the attendant competitive pressure and potential adverse consequences. Such competitive products may
be able to immediately compete with us in each indication for which our product candidates may have received approval.
Any legal proceedings or claims involving or against us could be costly and time-consuming to defend and could harm our reputation regardless of the
outcome.
We may in the future become subject to legal proceedings and claims that arise in the ordinary course of business, including intellectual property,
data privacy, product liability, employment, class action or derivative, whistleblower and other litigation claims, and governmental and other regulatory
investigations and proceedings. Such matters can be time-consuming, divert management’s attention and resources, cause us to incur significant expenses
or liability, or require us to change our business practices. In addition, the expense of litigation and the timing of this expense from period to period are
difficult to estimate, subject to change, and could adversely affect our financial condition and results of operations. Because of the potential risks, expenses,
and uncertainties of litigation, we may, from time to time, settle disputes, even where we have meritorious claims or defenses, by agreeing to settlement
agreements. Any of the foregoing could adversely affect our business, financial condition, and results of operations.
62
If product liability lawsuits are brought against us, we may incur substantial liabilities and may be required to limit commercialization of our product
candidates.
We face an inherent risk of product liability as a result of the clinical testing of our product candidates and will face an even greater risk when and if
we commercialize any products. For example, we may be sued if our product candidates cause or are perceived to cause injury or are found to be otherwise
unsuitable during clinical testing, manufacturing, marketing, or sale. Any such product liability claims may include allegations of defects in manufacturing,
defects in design, a failure to warn of dangers inherent in the product, negligence, strict liability, or a breach of warranties. Claims could also be asserted
under state consumer protection acts. If we cannot successfully defend ourselves against product liability claims, we may incur substantial liabilities or be
required to limit testing and commercialization of our product candidates. Even successful defense would require significant financial and management
resources. Regardless of the merits or eventual outcome, liability claims may result in:
•
•
•
•
•
•
•
•
•
•
•
decreased or interrupted demand for our products;
injury to our reputation;
withdrawal of clinical trial participants and inability to continue clinical trials;
initiation of investigations by regulators;
costs to defend the related litigation;
a diversion of management’s time and our resources;
substantial monetary awards to trial participants or patients;
product recalls, withdrawals or labeling, marketing, or promotional restrictions;
loss of revenue;
exhaustion of any available insurance and our capital resources; and
the inability to commercialize any product candidate.
Our inability to obtain sufficient product liability insurance at an acceptable cost to protect against potential product liability claims could prevent or
inhibit the commercialization of products we develop, alone or with collaborators. Our insurance policies may have various exclusions, and we may be
subject to a product liability claim for which we have no coverage. We may have to pay any amounts awarded by a court or negotiated in a settlement that
exceed our coverage limitations or that are not covered by our insurance, and we may not have, or be able to obtain, sufficient capital to pay such amounts.
Even if our agreements with any future corporate collaborators entitle us to indemnification against losses, such indemnification may not be available or
adequate should any claim arise.
Risks Related to Regulatory Approval and Other Legal Compliance Matters
The regulatory approval processes of the FDA, EMA, and comparable foreign regulatory authorities are lengthy, time consuming, and inherently
unpredictable. If we are ultimately unable to obtain regulatory approval for our product candidates, we will be unable to generate product revenue and
our business will be substantially harmed.
The time required to obtain approval by the FDA, EMA, and comparable foreign regulatory authorities is unpredictable, typically takes many years
following the commencement of clinical trials, and depends upon numerous factors, including the type, complexity, and novelty of the product candidates
involved. In addition, approval policies, regulations, or the type and amount of clinical data necessary to gain approval may change during the course of a
product candidate’s clinical development and may vary among jurisdictions, which may cause delays in the approval or the decision not to approve an
application. Regulatory authorities have substantial discretion in the approval process and may refuse to accept any application or may decide that our data
are insufficient for approval and require additional preclinical, clinical, or other studies. We have not submitted for, or obtained regulatory approval for any
product candidate, and it is possible that none of our existing product candidates or any product candidates we may seek to develop in the future will ever
obtain regulatory approval.
Further, development of our product candidates and/or regulatory approval may be delayed for reasons beyond our control. For example, the U.S.
federal government has experienced and may in the future experience shutdown
63
or budget sequestration, which could result in significant reductions to the FDA’s budget, employees, and operations, which may lead to slower response
times and longer review periods, potentially affecting our ability to progress development of our product candidates or obtain regulatory approval for our
product candidates. To the extent FDA and other regulatory authorities experience any delays or limited resources in reviewing our regulatory applications
or requests for meetings and/or guidance, and inspection of manufacturing facilities prior to regulatory approval due to the effects of the COVID-19
pandemic or other reasons, we may experience significant delays in our anticipated timelines for our clinical studies and/or seeking regulatory approvals,
which could adversely affect our business.
Applications for our product candidates could fail to receive regulatory approval in an initial or subsequent indication for many reasons, including
but not limited to the following:
•
•
•
•
•
•
•
•
the FDA, EMA, or comparable foreign regulatory authorities may disagree with the design, implementation, or the interpretation of the
results of our clinical trials;
the FDA, EMA, or comparable foreign regulatory authorities may determine that our product candidates are not safe and effective, only
moderately or insufficiently effective or have undesirable or unintended side effects, toxicities, or other characteristics that preclude our
obtaining marketing approval or prevent or limit commercial use;
the population studied in the clinical program may not be sufficiently broad or representative to assure efficacy and safety in the full
population for which we seek approval
the FDA, EMA, or comparable foreign regulatory authorities may disagree with our interpretation of data from preclinical studies or
clinical trials;
the data collected from clinical trials of our product candidates may not be sufficient to support the submission of an NDA, BLA, or other
submission or to obtain regulatory approval in the United States or elsewhere;
we may be unable to demonstrate to the FDA, EMA or comparable foreign regulatory authorities that a product candidate’s risk-benefit
ratio, on its own or when compared to the standard of care, is acceptable;
the FDA, EMA, or comparable foreign regulatory authorities may fail to approve the manufacturing processes, test procedures, and
specifications, or facilities of third-party manufacturers with which we contract for clinical and commercial supplies; and
the approval policies or regulations of the FDA, EMA, or comparable foreign regulatory authorities may significantly change in a manner
rendering our clinical data insufficient for approval or resulting in delays in our regulatory approval, including, for example, in connection
with the FDA’s approval of Biogen’s Aduhelm in Alzheimer’s disease amid questions regarding the underlying data, as well as the ongoing
government investigation of the FDA’s approval process for Aduhelm.
This lengthy approval process, as well as the unpredictability of the results of clinical trials, may result in our failing to obtain regulatory approval to
market any of our product candidates, which would significantly harm our business, results of operations, and growth prospects.
Our product candidates may cause undesirable side effects or have other properties that could halt their clinical development, prevent their regulatory
approval, limit their commercial potential, or result in significant negative consequences.
Adverse events or other undesirable side effects caused by our product candidates could cause us or regulatory authorities to interrupt, delay, or halt
clinical trials and could result in a more restrictive label or the delay or denial of regulatory approval by the FDA, EMA, or other comparable foreign
regulatory authorities.
Drug-related side effects could affect patient recruitment, the ability of enrolled patients to complete the study, and/or result in potential product
liability claims. We are required to maintain product liability insurance pursuant to certain of our development and commercialization agreements. We may
not be able to maintain insurance coverage at a reasonable cost or in sufficient amounts to protect us against losses due to liability. A successful product
liability claim or series of claims brought against us could adversely affect our results of operations, business, and
64
reputation. In addition, regardless of merit or eventual outcome, product liability claims may result in impairment of our business reputation, withdrawal of
clinical trial participants, costs due to related litigation, distraction of management’s attention from our primary business, initiation of investigations by
regulators, substantial monetary awards to patients or other claimants, the inability to commercialize our product candidates, and decreased demand for our
product candidates, if approved for commercial sale.
ARIA have been observed in our ongoing INVOKE-2 Phase 2 clinical trial in AD. ARIA are MRI findings suggestive of vasogenic edema or
hemosiderin deposits. The incidence of ARIA has been shown to increase in AD patients with the administration of certain Alzheimer's disease
therapeutics, namely anti-β-amyloid antibodies. In our INVOKE-2 Phase 2 clinical trial, most ARIA cases were asymptomatic and non-serious. However, a
small number of ARIA-related serious adverse events occurred almost exclusively in patients with the APOE e4/e4 genotype, as previously reported. To
mitigate risks associated with ARIA, we voluntarily discontinued dosing and enrollment of APOE e4/e4 participants in our INVOKE-2 Phase 2 clinical
trial. Following these changes, a small number of ARIA-related serious adverse events occurred in patients who are non-homozygous for the APOE e4
allele. We continue to implement earlier MRI monitoring, consistent with recently published guidelines for ARIA monitoring and management. We are
conducting this study under the guidance of an IDMC, which is allowed to review unblinded data and to make trial recommendations.
Additionally, if one or more of our product candidates receives marketing approval, and we or others later identify undesirable side effects or
adverse events caused by such products, a number of potentially significant negative consequences could result, including but not limited to:
•
•
•
•
•
•
regulatory authorities may withdraw approvals of such product and cause us to recall our products;
regulatory authorities may require additional warnings on the label;
we may be required to change the way the product is administered, monitor patients over the course of treatment, or conduct additional
clinical trials or post-approval studies;
we may be required to create a Risk Evaluation and Mitigation Strategy plan, which could include a medication guide outlining the risks of
such side effects for distribution to patients, a communication plan for healthcare providers, requiring pre-prescription screening or ongoing
monitoring for ARIA and/or other adverse events, and/or other elements, such as boxed warning on the packaging, to assure safe use;
we could be sued and held liable for harm caused to patients; and
our reputation may suffer.
Any of these events could prevent us from achieving or maintaining market acceptance of the particular product candidate, if approved, and could
significantly harm our business, financial condition, results of operations, and growth prospects.
We currently are and may continue in the future to conduct clinical trials for our product candidates outside the United States, and the FDA, EMA,
and applicable foreign regulatory authorities may not accept data from such trials.
We currently are and may continue in the future choose to conduct one or more of our clinical trials outside the United States, including in Europe,
Latin America, Asia or Australia. The acceptance of study data from clinical trials conducted outside the United States or another jurisdiction by the FDA,
EMA, or applicable foreign regulatory authority may be subject to certain conditions. In cases where data from foreign clinical trials are intended to serve
as the basis for marketing approval in the United States, the FDA will generally not approve the application on the basis of foreign data alone unless (i) the
data are applicable to the United States population and United States medical practice; and (ii) the trials were performed by clinical investigators of
recognized competence and pursuant to cGCP regulations. Additionally, the FDA’s clinical trial requirements, including sufficient size of patient
populations and statistical powering, must be met. Many foreign regulatory bodies have similar approval requirements. In addition, such foreign trials
would be subject to the applicable local laws of the foreign jurisdictions where the trials are conducted. There can be no assurance that the FDA, EMA, or
any applicable foreign regulatory authority will accept data from trials conducted outside of the United States or the applicable jurisdiction, as regulatory
authorities in different jurisdictions may impose different requirements for approval,
65
including requirements with respect to trial design or trial diversity. If the FDA, EMA, or any applicable foreign regulatory authority does not accept such
data, it would result in the need for additional trials, which would be costly and time-consuming and delay aspects of our business plan, and which may
result in our product candidates not receiving approval or clearance for commercialization in the applicable jurisdiction. Our reliance on genetic screening
and use of biomarkers to align patient risk profiles with targeted intervention may eventually require us to develop and use companion diagnostics, which
could result in additional regulatory requirements that would need to be met to enable its use.
Obtaining and maintaining regulatory approval of our product candidates in one jurisdiction does not mean that we will be successful in obtaining
regulatory approval of our product candidates in other jurisdictions.
Obtaining and maintaining regulatory approval of our product candidates in one jurisdiction does not guarantee that we will be able to obtain or
maintain regulatory approval in any other jurisdiction, but a failure or delay in obtaining regulatory approval in one jurisdiction may have a negative effect
on the regulatory approval process in others. For example, even if the FDA or EMA grants marketing approval of a product candidate, comparable
regulatory authorities in foreign jurisdictions must also approve the manufacturing, marketing, and promotion of the product candidate in those countries.
Approval procedures vary among jurisdictions and can involve requirements and administrative review periods different from those in the United States,
including additional preclinical studies or clinical trials as clinical trials conducted in one jurisdiction may not be accepted by regulatory authorities in other
jurisdictions. In many jurisdictions outside the United States, a product candidate must be approved for reimbursement before it can be approved for sale in
that jurisdiction. In some cases, the price that we intend to charge for our products is also subject to regulatory approval.
Obtaining foreign regulatory approvals and compliance with foreign regulatory requirements could result in significant delays, difficulties, and costs
for us and could delay or prevent the introduction of our products in certain countries. If we or any partner we work with fail to comply with the regulatory
requirements in international markets or fail to receive applicable marketing approvals, our target market will be reduced, and our ability to realize the full
market potential of our product candidates will be harmed.
Even if we obtain regulatory approval for a product candidate, our products will remain subject to extensive post-marketing requirements and
regulatory scrutiny.
If any of our product candidates are approved, they will be subject to ongoing regulatory requirements for manufacturing, labeling, packaging,
storage, advertising, promotion, sampling, record-keeping, conduct of post-marketing studies, and submission of safety, efficacy, and other post-market
information, including both federal and state requirements in the United States and requirements of comparable foreign regulatory authorities.
Manufacturers and manufacturers’ facilities are required to comply with extensive requirements imposed by the FDA, EMA, and comparable
foreign regulatory authorities, including ensuring that quality control and manufacturing procedures conform to cGMP regulations. As such, we and our
contract manufacturers will be subject to continual review and inspections to assess compliance with cGMP and adherence to commitments made in any
NDA, BLA, or marketing authorization application (MAA). Accordingly, we and others with whom we work must continue to expend time, money, and
effort in all areas of regulatory compliance, including manufacturing, production, and quality control.
Any regulatory approvals that we receive for our product candidates will be subject to limitations on the approved indicated uses for which the
product may be marketed and promoted or to the conditions of approval (including any requirement to implement a Risk Evaluation and Mitigation
Strategy), or contain requirements for potentially costly post-marketing testing. We will be required to report certain adverse reactions and production
problems, if any, to the FDA, EMA, and comparable foreign regulatory authorities. Any new legislation addressing drug safety issues could result in delays
in product development or commercialization, or increased costs to assure compliance. The FDA and other agencies, including the Department of Justice,
closely regulate and monitor the post-approval marketing and promotion of products to ensure that they are manufactured, marketed, and distributed only
for the approved indications and in accordance with the provisions of the approved labeling. We will have to comply with requirements concerning
advertising and promotion for our products. Promotional communications with respect to prescription drugs are subject to a variety of legal and regulatory
restrictions and must be consistent with the information in the product’s approved label. As such, we may not promote our products for indications or uses
for which they do not have approval. The holder of an approved NDA, BLA, or MAA must submit new or
66
supplemental applications and obtain approval for certain changes to the approved product, product labeling, or manufacturing process. We could also be
asked to conduct post-marketing clinical trials to verify the safety and efficacy of our products in general or in specific patient subsets. If original marketing
approval was obtained via the accelerated approval pathway, we could be required to conduct a successful post-marketing clinical trial to confirm clinical
benefit for our products. An unsuccessful post-marketing study or failure to complete such a study could result in the withdrawal of marketing approval.
If a regulatory agency discovers previously unknown problems with a product, such as adverse events of unanticipated severity or frequency, or
problems with the facility where the product is manufactured, or disagrees with the promotion, marketing or labeling of a product, such regulatory agency
may impose restrictions on that product or us, including requiring withdrawal of the product from the market. If we fail to comply with applicable
regulatory requirements, a regulatory agency or enforcement authority may, among other things:
•
•
•
•
•
•
•
•
issue warning letters that would result in adverse publicity;
impose civil or criminal penalties;
suspend or withdraw regulatory approvals;
suspend any of our ongoing clinical trials;
refuse to approve pending applications or supplements to approved applications submitted by us;
impose restrictions on our operations, including closing our contract manufacturers’ facilities;
seize or detain products; or
require a product recall.
Any government investigation of alleged violations of law could require us to expend significant time and resources in response and could generate
negative publicity. Any failure to comply with ongoing regulatory requirements may significantly and adversely affect our ability to commercialize and
generate revenue from our products. If regulatory sanctions are applied or if regulatory approval is withdrawn, the value of our company and our operating
results will be adversely affected.
We have received orphan drug designation from the FDA for latozinemab and AL101 for treatment of FTD and may seek orphan drug designation for
some of our other product candidates, but we may be unable to obtain such designations or to maintain the benefits associated with orphan drug status,
including market exclusivity, which may cause our revenue, if any, to be reduced.
Under the Orphan Drug Act, the FDA may grant orphan designation to a drug or biologic intended to treat a rare disease or condition, defined as a
disease or condition with a patient population of fewer than 200,000 in the United States, or a patient population greater than 200,000 in the United States
when there is no reasonable expectation that the cost of developing and making available the drug or biologic in the United States will be recovered from
sales in the United States for that drug or biologic. Orphan drug designation must be requested before submitting an NDA or BLA. In the United States,
orphan drug designation entitles a party to financial incentives such as opportunities for grant funding towards clinical trial costs, tax advantages, and user-
fee waivers. After the FDA grants orphan drug designation, the generic identity of the drug and its potential orphan use are disclosed publicly by the FDA.
Orphan drug designation does not convey any advantage in, or shorten the duration of, the regulatory review and approval process. While we have obtained
orphan drug designation from the FDA for latozinemab and AL101 for treatment of FTD, we may be unable to reap the benefits associated with orphan
drug status. In addition, we plan to seek orphan drug designations for some of our other product candidates in the future but may be unable to obtain an
orphan drug designation for any additional product candidates.
If a product that has orphan drug designation subsequently receives the first FDA approval for a particular active ingredient for the disease for which
it has such designation, the product is entitled to orphan drug exclusivity. This means that the FDA may not approve any other NDA or BLA application to
market the same drug or biologic for the same indication for seven years, except in limited circumstances such as a showing of clinical superiority to the
product with orphan exclusivity, if FDA revokes the orphan drug designation, or if FDA finds that the holder of the orphan exclusivity has not assured the
availability of sufficient quantities of the orphan product to meet the needs of patients with the disease or condition for which the drug was designated.
Even though the FDA has
67
approved orphan drug status for latozinemab and AL101 for treatment of FTD, the FDA can still approve other drugs that have a different active ingredient
for use in treating FTD. Furthermore, orphan drug exclusivity does not prevent the FDA from approving another marketing application for the same drug
product for a different indication before the expiration of the orphan exclusivity period.
As discussed above, in litigation in 2021, a court disagreed with the FDA’s longstanding position that orphan drug exclusivity only applies to the
approved use or indication within an eligible disease, and not to all uses or indications within the entire designated disease or condition. This appellate
court decision created uncertainty in the application of orphan drug exclusivity. In January, 2023, the FDA published a notice in the Federal Register to
clarify that while the agency complies with the applicable court ruling. The FDA intends to continue tying the scope of orphan-drug exclusivity to the uses
or indications for which a drug is approved, which permits other sponsors to obtain approval of a drug for new uses or indications within the same orphan
designated disease or condition that has not yet been approved. It is unclear how future litigation, legislation, agency decisions, and administrative actions
will impact the scope of orphan drug exclusivity.
We have received Fast Track designation from the FDA for latozinemab and AL101 for the treatment of patients with FTD carrying specific genetic
mutation in the granulin gene, but we may be unable to obtain or maintain the benefits associated with the Fast Track designation.
Fast Track designation is designed to facilitate the development and expedite the review of therapies which treat serious conditions and fill an unmet
medical need. Programs with Fast Track designation may benefit from early and frequent communications with the FDA, potential priority review, and the
ability to submit a rolling application for regulatory review. Fast Track designation applies to both the product and the specific indication for which it is
being studied.
In December 2019, the FDA granted Fast Track designation for latozinemab and in January 2020, the FDA granted Fast Track designation for
AL101, each for the treatment of patients with FTD carrying specific genetic mutations in the granulin gene. If our clinical development program does not
continue to meet the criteria for Fast Track designation, or if our clinical trials are suspended or terminated, or put on clinical hold due to unexpected
adverse events or issues with clinical supply, we may not realize all the benefits associated with the Fast Track program. Furthermore, Fast Track
designation does not change the standards for approval. Fast Track designation alone does not guarantee qualification for the FDA’s priority review
procedures.
Healthcare legislative measures aimed at reducing healthcare costs may have a material adverse effect on our business and results of operations.
Third-party payors, whether domestic or foreign, or governmental or commercial, are developing increasingly sophisticated methods of controlling
healthcare costs. In both the United States and certain foreign jurisdictions, there have been a number of legislative and regulatory changes to the healthcare
system that could impact our ability to sell our products profitably.
In particular, in 2010, the Patient Protection and Affordable Care Act, or Affordable Care Act (ACA) was enacted, which, among other things,
subjected biologic products to potential competition by lower-cost biosimilars, addressed a new methodology by which rebates owed by manufacturers
under the Medicaid Drug Rebate Program are calculated for drugs that are inhaled, infused, instilled, implanted, or injected, increased the minimum
Medicaid rebates owed by most manufacturers under the Medicaid Drug Rebate Program, extended the Medicaid Drug Rebate Program to utilization of
prescriptions of individuals enrolled in Medicaid managed care organizations, subjected manufacturers to new annual fees and taxes for certain branded
prescription drugs, and provided incentives to programs that increase the federal government’s comparative effectiveness research. In June 2021, the United
States Supreme Court held that Texas and other challengers had no legal standing to challenge the ACA, dismissing the case without specifically ruling on
the constitutionality of the ACA. Accordingly, the ACA remains in effect in its current form. It is unclear how this Supreme Court decision, future
litigation, or healthcare measures promulgated by the Biden administration will impact our business, financial condition, and results of operations.
Complying with any new legislation or changes in healthcare regulation could be time-intensive and expensive, resulting in a material adverse effect on our
business.
Under the American Rescue Plan Act of 2021, effective January 1, 2024, the statutory cap on Medicaid Drug Rebate Program rebates that
manufacturers pay to state Medicaid programs will be eliminated. Elimination of this cap may require pharmaceutical manufacturers to pay more in rebates
than they receive on the sale of approved
68
products, which could have a material impact on our business. In August 2022, Congress passed the Inflation Reduction Act of 2022, which includes
prescription drug provisions that have significant implications for the pharmaceutical industry and Medicare beneficiaries, including allowing the federal
government to negotiate a maximum fair price for certain high-priced single source Medicare drugs, imposing penalties and excise tax for manufacturers
that fail to comply with the drug price negotiation requirements, requiring inflation rebates for all Medicare Part B and Part D drugs, with limited
exceptions, if their drug prices increase faster than inflation, and redesigning Medicare Part D to reduce out-of-pocket prescription drug costs for
beneficiaries, among other changes. The implementation of cost containment measures or other healthcare reforms may prevent us from being able to
generate revenue, attain profitability, or commercialize our product candidates if approved.
Many states have proposed or enacted legislation that seeks to indirectly or directly regulate pharmaceutical drug pricing, such as by requiring
biopharmaceutical manufacturers to publicly report proprietary pricing information or to place a maximum price ceiling on pharmaceutical products
purchased by state agencies. For example, a number of states are considering or have recently enacted state drug price transparency and reporting laws that
could substantially increase our compliance burdens and expose us to greater liability under such state laws once we begin commercialization after
obtaining regulatory approval for any of our products candidates. Such initiatives and legislation may affect the prices we may obtain or demand for any of
our product candidates for which we may obtain regulatory approval.
Further, in April 2022, CMS released a national policy for coverage of aducanumab and any future monoclonal antibodies directed against amyloid
approved by the FDA with an indication for use in treating Alzheimer’s disease. CMS reiterated this policy in January 2023 in connection with the
approval of lecanemab. According to the two-part National Coverage Determination (NCD), Medicare will cover monoclonal antibodies that target
amyloid (or plaque) for the treatment of Alzheimer’s disease that receive traditional approval from the FDA when furnished in accordance with the
coverage criteria specified below under coverage with evidence development. CMS will also provide enhanced access and coverage for Medicare patients
participating in CMS-approved studies, such as a data collection through routine clinical practice or registries. Additionally, for drugs that FDA has not
determined to have shown a clinical benefit or that received an accelerated approval, Medicare will provide coverage in FDA or National Institutes of
Health approved clinical trials. Current and future CMS coverage restrictions on classes of drugs that encompass our product candidates could have a
material adverse impact on our ability to commercialize our product candidates, if approved, generate revenue and attain profitability. It is unclear how
future CMS coverage decisions and policies will impact our business.
At the state level, legislatures have increasingly passed legislation and implemented regulations designed to control pharmaceutical and biological
product pricing, including price or patient reimbursement constraints, discounts, restrictions on certain product access and marketing cost disclosure and
transparency measures, and, in some cases, designed to encourage importation from other countries and bulk purchasing. A number of states are
considering or have recently enacted state drug price transparency and reporting laws that could substantially increase our compliance burdens and expose
us to greater liability under such state laws once we begin commercialization after obtaining regulatory approval for any of our products.
We are unable to predict the future course of federal or state healthcare legislation in the United States directed at broadening the availability of
healthcare and containing or lowering the cost of healthcare. These and any further changes in the law or regulatory framework that reduce our revenue or
increase our costs could also have a material and adverse effect on our business, financial condition and results of operations.
The continuing efforts of the government, insurance companies, managed care organizations, and other payors of healthcare services to contain or
reduce costs of healthcare and/or impose price controls may adversely affect:
•
•
•
•
•
the demand for our product, if we obtain regulatory approval;
our ability to receive or set a price that we believe is fair for our products;
our ability to generate revenue and achieve or maintain profitability;
the level of taxes that we are required to pay; and
the availability of capital.
69
We expect that the above healthcare reform measures and others that may be adopted in the future, may result in additional reductions in Medicare
and other healthcare funding, more rigorous coverage criteria, lower reimbursement, and new payment methodologies. Any reduction in reimbursement
from Medicare or other government programs may result in a similar reduction in payments from private payors. This could lower the price that we receive
for any approved product. The Biden administration and the states may pass further legislation and regulations designed to control pharmaceutical and
biological product pricing, including price or patient reimbursement constraints, discounts, restrictions on certain product access and marketing cost
disclosure and transparency measures. Any denial in coverage or reduction in reimbursement from Medicare or other government-funded programs may
result in a similar denial or reduction in payments from private payors, which may prevent us from being able to generate sufficient revenue, attain
profitability, or commercialize our product candidates, if approved. In addition, increased scrutiny by the U.S. Congress of the FDA’s approval process may
significantly delay or prevent marketing approval, as well as subject us to more stringent product labeling and post-marketing testing and other
requirements.
Our employees, independent contractors, consultants, commercial partners, and vendors may engage in misconduct or other improper activities,
including noncompliance with regulatory standards and requirements.
We are exposed to the risk of fraud, misconduct, or other illegal activity by our employees, independent contractors, consultants, commercial
partners, and vendors. Misconduct by these parties could include intentional, reckless, and negligent conduct that fails to:
•
•
•
•
•
comply with the laws of the FDA, EMA, and other comparable foreign regulatory authorities;
provide true, complete, and accurate information to the FDA, EMA, and other comparable foreign regulatory authorities;
comply with clinical or manufacturing standards;
comply with healthcare fraud and abuse laws in the United States and similar foreign fraudulent misconduct laws; or
report financial information or data accurately or to disclose unauthorized activities to us.
If we obtain FDA approval of any of our product candidates and begin commercializing those products in the United States, our potential exposure
under such laws will increase significantly, and our costs associated with compliance with such laws are also likely to increase. In particular, research,
sales, marketing, education, and other business arrangements in the healthcare industry are subject to extensive laws designed to prevent fraud, kickbacks,
self-dealing, and other abusive practices. These laws and regulations may restrict or prohibit a wide range of pricing, discounting, educating, marketing and
promotion, sales and commission, certain customer incentive programs, and other business arrangements generally. We have adopted a code of business
conduct and ethics, but it is not always possible to identify and deter misconduct by employees and third parties, and the precautions we take to detect and
prevent this activity may not be effective in controlling unknown or unmanaged risks or losses or in protecting us from governmental investigations or
other actions or lawsuits stemming from a failure to be in compliance with such laws. If any such actions are instituted against us, and we are not successful
in defending ourselves or asserting our rights, those actions could have a significant impact on our business, including the imposition of significant fines or
other sanctions.
If we fail to comply with healthcare laws, we could face substantial penalties and our business, operations, and financial conditions could be adversely
affected.
If we obtain FDA approval for any of our product candidates and begin commercializing those products in the United States, our operations will be
subject to various federal and state fraud and abuse laws. The laws that may impact our operations include the following:
•
Among other things the federal Anti-Kickback Statute, prohibits, persons from knowingly and willfully soliciting, receiving, offering, or
paying any remuneration (including any kickback, bribe, or rebate), directly or indirectly, overtly or covertly, in cash or in kind, to induce,
or in return for, either the referral of an individual, or the purchase, lease, order, or recommendation of any good, facility, item or service for
which payment may be made, in whole or in part, under a federal healthcare program, such as the Medicare and Medicaid programs. A
person or entity does not need to have
70
actual knowledge of the statute or specific intent to violate it in order to have committed a violation. In addition, the government may assert
that a claim including items or services resulting from a violation of the federal Anti-Kickback Statute constitutes a false or fraudulent
claim for purposes of the False Claims Act.
Federal civil and criminal false claims laws and civil monetary penalty laws, including the False Claims Act, impose criminal and civil
penalties, including through civil “qui tam” or “whistleblower” actions, against individuals or entities from knowingly presenting, or
causing to be presented, claims for payment or approval from Medicare, Medicaid, or other third-party payors that are false or fraudulent or
knowingly making a false statement to improperly avoid, decrease, or conceal an obligation to pay money to the federal government.
Similar to the federal Anti-Kickback Statute, a person or entity does not need to have actual knowledge of these statutes or specific intent to
violate them in order to have committed a violation.
The federal Health Insurance Portability and Accountability Act of 1996 (HIPAA) created new federal criminal statutes that prohibit
knowingly and willfully executing, or attempting to execute, a scheme to defraud any healthcare benefit program or obtain, by means of
false or fraudulent pretenses, representations, or promises, any of the money or property owned by, or under the custody or control of, any
healthcare benefit program, regardless of the payor (e.g., public or private) and knowingly and willfully falsifying, concealing, or covering
up by any trick or device a material fact or making any materially false statements in connection with the delivery of, or payment for,
healthcare benefits, items or services relating to healthcare matters.
HIPAA, as amended by the Health Information Technology for Economic and Clinical Health Act of 2009 (HITECH) and their respective
implementing regulations, impose requirements on certain covered healthcare providers, health plans, and healthcare clearinghouses as well
as their respective business associates that perform services for them that involve the use, or disclosure of, individually identifiable health
information, relating to the privacy, security, and transmission of individually identifiable health information without appropriate
authorization.
The federal Physician Payment Sunshine Act, created under the ACA, and its implementing regulations, require applicable manufacturers
of drugs, devices, biologicals, and medical supplies for which payment is available under Medicare, Medicaid, or the Children’s Health
Insurance Program to report annually to the U.S. Department of Health and Human Services under the Open Payments Program,
information related to payments and other transfers of value made to covered recipients, including physicians (defined to include doctors,
dentists, optometrists, podiatrists and chiropractors), certain non-physician healthcare professionals (such as nurse practitioners and
physician assistants, among others) and teaching hospitals, and information regarding ownership and investment interests held by
physicians (as defined by law) and their immediate family members.
Federal consumer protection and unfair competition laws broadly regulate marketplace activities and activities that potentially harm
consumers.
Analogous state and foreign laws and regulations, such as state and foreign anti-kickback, false claims, consumer protection, and unfair
competition laws may apply to pharmaceutical business practices, including but not limited to, research, distribution, sales, and marketing
arrangements, as well as submitting claims involving healthcare items or services reimbursed by any third-party payer, including
commercial insurers.
State laws require pharmaceutical companies to comply with the pharmaceutical industry’s voluntary compliance guidelines, and the
relevant compliance guidance promulgated by the federal government that otherwise restricts payments that may be made to healthcare
providers and other potential referral sources.
State laws also require drug manufacturers to file reports with states regarding pricing and marketing information, such as the tracking and
reporting of gifts, compensations and other remuneration, and items of value provided to healthcare professionals and entities.

State and foreign laws also govern the privacy and security of health information in certain circumstances, many of which differ from each
other in significant ways and may not have the same effect, thus complicating compliance efforts.
Because of the breadth of these laws and the narrowness of the statutory exceptions and safe harbors available, it is possible that some of our
business activities could, despite our efforts to comply, be subject to challenge under one or more of such laws. Efforts to ensure that our business
arrangements will comply with applicable healthcare laws may involve substantial costs. It is possible that governmental and enforcement authorities will
conclude that our business practices may not comply with current or future statutes, regulations or case law interpreting applicable fraud and abuse or other
healthcare laws and regulations. If any such actions are instituted against us, and we are not successful in defending ourselves or asserting our rights, those
actions could have a significant impact on our business, including the imposition of civil, criminal, and administrative penalties, damages, disgorgement,
monetary fines, possible exclusion from participation in Medicare, Medicaid, and other federal healthcare programs, contractual damages, reputational
harm, diminished profits and future earnings, and curtailment of our operations, any of which could adversely affect our ability to operate our business and
our results of operations. In addition, the approval and commercialization of any of our product candidates outside the United States will also likely subject
us to foreign equivalents of the healthcare laws mentioned above, among other foreign laws.
If we or any contract manufacturers and suppliers we engage fail to comply with environmental, health, and safety laws and regulations, we could
become subject to fines or penalties or incur costs that could have a material adverse effect on our business.
We and any contract manufacturers and suppliers we engage are subject to numerous federal, state, and local environmental, health, and safety laws,
regulations, and permitting requirements, including those governing laboratory procedures; the generation, handling, use, storage, treatment, and disposal
of hazardous and regulated materials and wastes; the emission and discharge of hazardous materials into the ground, air, and water; and employee health
and safety. Our operations involve the use of hazardous and flammable materials, including chemicals and biological and radioactive materials. Our
operations also produce hazardous waste. We generally contract with third parties for the disposal of these materials and wastes. We cannot eliminate the
risk of contamination or injury from these materials. In the event of contamination or injury resulting from our use of hazardous materials, we could be held
liable for any resulting damages, and any liability could exceed our resources. Under certain environmental laws, we could be held responsible for costs
relating to any contamination at our current or past facilities and at third-party facilities. We also could incur significant costs associated with civil or
criminal fines and penalties.
Compliance with applicable environmental laws and regulations may be expensive, and current or future environmental laws and regulations may
impair our research, product development, and manufacturing efforts. In addition, we cannot entirely eliminate the risk of accidental injury or
contamination from these materials or wastes. Although we maintain workers’ compensation insurance to cover us for costs and expenses we may incur
due to injuries to our employees resulting from the use of hazardous materials, this insurance may not provide adequate coverage against potential
liabilities. We do not carry specific biological or hazardous waste insurance coverage, and our property, casualty, and general liability insurance policies
specifically exclude coverage for damages and fines arising from biological or hazardous waste exposure or contamination. Accordingly, in the event of
contamination or injury, we could be held liable for damages or be penalized with fines in an amount exceeding our resources, and our clinical trials or
regulatory approvals could be suspended, which could have a material adverse effect on our business, financial condition, results of operations, and
prospects.
Our business is subject to complex and evolving U.S. and foreign laws and regulations relating to security, privacy and data protection. These laws and
regulations are subject to change and uncertain interpretation, and could result in claims, changes to our business practices, or monetary penalties,
and otherwise may harm our business.
A wide variety of state, national, and international laws and regulations apply to security and cybersecurity requirements and the collection, use,
retention, protection, disclosure, transfer, and other processing of personal data. These security and data protection and privacy-related laws and regulations
are evolving and may result in ever-increasing regulatory and public scrutiny and escalating levels of enforcement and sanctions. We are continually
working to comply with these laws, and we anticipate needing to devote significant additional resources to our compliance efforts. It is possible that the
new legislation may impose new obligations and requirements on similarly
72
situated companies, and these laws may be interpreted and applied in a manner that is inconsistent from jurisdiction to jurisdiction or inconsistent with our
current policies and practices. Our actual or perceived failure to adequately comply with applicable laws and regulations relating to security, privacy and
data protection, or to protect our systems, personal data and other data we process or maintain, could result in regulatory fines, investigations and
enforcement actions, penalties and other liabilities, claims for damages by affected individuals, and damage to our reputation, any of which could
materially affect our business, financial condition, results of operations and prospects.
Inadequate funding for the FDA and other government agencies could hinder their ability to hire and retain key leadership and other personnel,
prevent new products and services from being developed or commercialized in a timely manner or otherwise prevent those agencies from performing
normal business functions on which the operation of our business may rely, which could negatively impact our business.
The ability of the FDA to review and approve new products can be affected by a variety of factors, including government budget and funding levels,
ability to hire and retain key personnel and accept the payment of user fees, and statutory, regulatory, and policy changes. Average review times at the
agency have fluctuated in recent years as a result. In addition, government funding of other government agencies on which our operations may rely,
including those that fund research and development activities is subject to the political process, which is inherently fluid and unpredictable. Disruptions at
the FDA and other agencies may also slow the time necessary for new drugs to be reviewed and/or approved by necessary government agencies, which
would adversely affect our business. In the past, the U.S. government has experienced budgetary shutdowns and certain regulatory agencies, such as the
FDA, have had to furlough critical FDA and other government employees and stop critical activities. If a prolonged government shutdown occurs, it could
significantly impact the ability of the FDA to timely review and process our regulatory submissions, which could have a material adverse effect on our
business. Further, in our operations as a public company, future government shutdowns could impact our ability to access the public markets and obtain
necessary capital in order to properly capitalize and continue our operations.
Our business activities may be subject to the Foreign Corrupt Practices Act (FCPA), similar anti-bribery and anti-corruption laws, and other
regulations.
Our business activities may be subject to the FCPA and similar anti-bribery or anti-corruption laws, regulations, or rules of other countries in which
we operate, including the U.K. Bribery Act. The FCPA generally prohibits offering, promising, giving, or authorizing others to give anything of value,
either directly or indirectly, to a non-U.S. government official in order to influence official action, or otherwise obtain or retain business. The FCPA also
requires public companies to make and keep books and records that accurately and fairly reflect the transactions of the corporation and to devise and
maintain an adequate system of internal accounting controls. Our business is heavily regulated and therefore involves significant interaction with public
officials, including officials of non-U.S. governments. Additionally, in many other countries, the healthcare providers who engage in our clinical trials or
prescribe pharmaceuticals are employed by their government, and the purchasers of pharmaceuticals are government entities; therefore, our dealings with
these investigators, prescribers and purchasers are subject to regulation under the FCPA.
Recently the SEC and Department of Justice have increased their FCPA enforcement activities with respect to biotechnology and pharmaceutical
companies. There is no certainty that all of our employees, agents, contractors, or collaborators, or those of our affiliates, will comply with all applicable
laws and regulations, particularly given the high level of complexity of these laws. Violations of these laws and regulations could result in fines, criminal
sanctions against us, our officers, or our employees, the closing down of our facilities, requirements to obtain export licenses, cessation of business
activities in sanctioned countries, implementation of compliance programs, and prohibitions on the conduct of our business. Any such violations could
include prohibitions on our ability to offer our products in one or more countries and could materially damage our reputation, our brand, our international
expansion efforts, our ability to attract and retain employees, and our business, prospects, operating results, and financial condition.
73
Risks Related to Our Reliance on Third Parties
We expect to depend on collaborations with third parties for the research, development, and commercialization of certain of the product candidates we
may develop. If any such collaborations are not successful, we may not be able to realize the market potential of those product candidates.
We currently use and expect to continue to use third-party collaborators for the research, development, and commercialization of certain of the
product candidates we may develop, including our arrangements with AbbVie, GSK, and Adimab.
Our likely collaborators for any other collaboration arrangements include large and mid-sized pharmaceutical companies, regional and national
pharmaceutical companies, biotechnology companies, and academic institutions. Such arrangements with any third parties, generally provide us with
shared or limited control over the amount and timing of resources that our collaborators dedicate to the development or potential commercialization of any
product candidates we may seek to develop with them. Our ability to generate revenue from these arrangements with commercial entities will depend on
our collaborators’ abilities to successfully perform the functions assigned to them in these arrangements. We cannot predict the success of our current
collaborations or any collaboration that we may enter into.
Collaborations involving our research programs, or any product candidates we may develop, pose risks to us including the following:
•
•
•
•
•
•
•
•
•
collaborators generally have significant discretion in determining the efforts and resources that they will apply to these collaborations;
collaborators may decide to not pursue development and commercialization of any product candidates we develop or may elect not to
continue or renew development or commercialization programs based on clinical trial results, changes in the collaborator’s strategic focus
or available funding or external factors such as an acquisition that diverts resources or creates competing priorities or collaborators may
elect to fund or commercialize a competing product;
collaborators may delay clinical trials, provide insufficient funding for a clinical trial program, provide insufficient quantities of materials
for a clinical trial program, stop a clinical trial or abandon a product candidate, repeat or conduct new clinical trials, or require a new
formulation of a product candidate for clinical testing;
collaborations may be terminated in their entirety or with respect to certain product candidates or technologies and, if so terminated, may
result in a need for additional capital to pursue further development or commercialization of the applicable product candidates or
technologies;
collaborators may not properly obtain, maintain, enforce, or defend intellectual property or proprietary rights relating to our product
candidates or research programs or may use our proprietary information in such a way as to expose us to potential litigation or other
intellectual property related proceedings, including proceedings challenging the scope, ownership, validity, and enforceability of our
intellectual property;
collaborators may own or co-own intellectual property covering our product candidates or research and development programs that results
from our collaboration with them, and in such cases, we may not have the exclusive right to commercialize such intellectual property or
such product candidates or research programs;
we may need the cooperation of our collaborators to enforce or defend any intellectual property we contribute to or that arises out of our
collaborations, which may not be provided to us;
collaborators may control certain interactions with regulatory authorities, which may impact our ability to obtain and maintain regulatory
approval of our product candidates;
disputes may arise between the collaborators and us that result in the delay or termination of the research, development, or
commercialization of our product candidates or research programs or that result in costly litigation or arbitration that diverts management
attention and resources;

collaborators could independently develop, or develop with third parties, products that compete directly or indirectly with our product
candidates or research programs if the collaborators believe that competitive products are more likely to be successfully developed or can
be commercialized under terms that are more economically attractive than ours;
collaborators may restrict us from researching, developing, or commercializing certain products or technologies without their involvement;
collaborators with manufacturing, marketing, or distribution rights to one or more product candidates may not commit sufficient resources
to the manufacture, marketing, or distribution of such product candidates;
we may lose certain valuable rights under circumstances identified in our collaborations, including if we undergo a change of control;
collaborators may grant sublicenses to our technology or product candidates or undergo a change of control, and the sublicensees or new
owners may decide to take the collaboration in a direction which is not in our best interest;
collaborators may become bankrupt, which may significantly delay our research or development programs, or may cause us to lose access
to valuable technology, know-how, or intellectual property of the collaborator relating to our products, product candidates, or research
programs;
key personnel at our collaborators may leave, which could negatively impact our ability to productively work with our collaborators;
collaborations may require us to incur short and long-term expenditures, issue securities that dilute our stockholders, or disrupt our
management and business;
if our collaborators do not satisfy their obligations under our agreements with them, if they terminate our collaborations with them, or if we
fail to satisfy our obligations to our collaborators, we may not be able to develop or commercialize product candidates as planned;
collaborations may require us to share in development and commercialization costs pursuant to budgets that we do not fully control, and our
failure to share in such costs could have a detrimental impact on the collaboration or our ability to share in revenue generated under the
collaboration and;
collaboration agreements may not lead to development or commercialization of product candidates in the most efficient manner or at all. If
a present or future collaborator of ours were to be involved in a business combination, the continued pursuit and emphasis on our
development or commercialization program under such collaboration could be delayed, diminished, or terminated.
For example, AbbVie, after reviewing the CD33 collaboration program with us, decided to terminate the CD33 collaboration program, under which
AL003 was being developed. Additionally, Innovent will not be conducting the AL008 first in human studies in China, Innovent will not be continuing
development of AL008, and we intend to re-acquire the rights we granted to Innovent for the development and commercialization of AL008. Innovent
submitted an IND with the Chinese regulatory authorities, and Alector is in the process of obtaining relevant materials and information from Innovent.
Alector plans to evaluate data and documentation from that IND application to potentially support an IND submission in the U.S.
We may face significant competition in seeking appropriate collaborations. For example business combinations among biotechnology and
pharmaceutical companies have resulted in a reduced number of potential collaborators. In addition, the negotiation process is time-consuming and
complex, and we may not be able to negotiate collaborations on a timely basis, on acceptable terms, or at all. If we are unable to do so, we may have to
curtail the development of the product candidate for which we are seeking to collaborate, reduce or delay its development program or one or more of our
other development programs, delay its potential commercialization or reduce the scope of any sales or marketing activities, or increase our expenditures
and undertake development or commercialization activities at our own expense. If we elect to increase our expenditures to fund development or
commercialization activities on our own, we may need to obtain additional capital, which may not be available to us
75
on acceptable terms or at all. If we do not have sufficient funds, we may not be able to further develop product candidates or bring them to market and
generate product revenue.
We may not realize the benefit of collaborations if we or our collaborator elects not to exercise the rights granted under the agreement or if we or our
collaborator are unable to successfully integrate a product candidate into existing operations and company culture. In addition, if our agreement with any of
our collaborators terminates, our access to technology and intellectual property licensed to us by that collaborator may be restricted or terminate entirely,
which may delay our continued development of our product candidates utilizing the collaborator’s technology or intellectual property or require us to stop
development of those product candidates completely. We may also find it more difficult to find a suitable replacement collaborator or attract new
collaborators, and our development programs may be delayed or the perception of us in the business and financial communities could be adversely affected.
Many of the risks relating to product development, regulatory approval, and commercialization described in this “Risk Factors” section also apply to the
activities of our collaborators and any negative impact on our collaborators may adversely affect us.
We expect to rely on third parties to conduct our clinical trials and some aspects of our research and preclinical testing, and those third parties may not
perform satisfactorily, including failing to meet deadlines for the completion of such trials, research, or testing.
We currently rely and expect to continue to rely on third parties, such as CROs, clinical data management organizations, medical institutions, and
clinical investigators, to conduct some aspects of our research and preclinical testing and our clinical trials. Any of these third parties may terminate their
engagements with us or be unable to fulfill their contractual obligations. If we need to enter into alternative arrangements, it would delay our product
development activities.
Our reliance on these third parties for research and development activities reduces our control over these activities but does not relieve us of our
responsibilities. For example, we remain responsible for ensuring that each of our clinical trials is conducted in accordance with the general investigational
plan and protocols for the trial. Moreover, the FDA requires us to comply with cGCPs for conducting, recording, and reporting the results of clinical trials
to assure that data and reported results are credible, reproducible, and accurate and that the rights, integrity, and confidentiality of trial participants are
protected. We also are required to register ongoing clinical trials and post the results of completed clinical trials on a government-sponsored databases
within certain timeframes. We may also be exposed to additional liabilities if our contracted third parties engage in activities associated with improper use
of information obtained in the course of patient recruitment for our clinical trials, cGCP noncompliance or noncompliance under applicable privacy laws,
which could result in regulatory sanctions and cause serious harm to our reputation and business operations. Failure to do so can result in fines, adverse
publicity, and civil and criminal sanctions.
If these third parties do not successfully carry out their contractual duties, meet expected deadlines, or conduct our clinical trials in accordance with
regulatory requirements or our stated protocols, we will not be able to obtain, or may be delayed in obtaining, marketing approvals for any product
candidates we may develop and will not be able to, or may be delayed in our efforts to, successfully commercialize our medicines.
We also expect to rely on other third parties to store and distribute drug supplies for our clinical trials. Any performance failure on the part of our
distributors, including with the shipment of any drug supplies, could delay clinical development or marketing approval of any product candidates we may
develop or commercialization of our medicines, producing additional losses and depriving us of potential product revenue.
We contract with third parties for the manufacture of materials for our research programs, preclinical studies, clinical trials, and for commercialization
of any product candidates that we may develop. Additionally, GSK, and AbbVie, have certain product manufacturing rights under their respective
agreements. This reliance on third parties carries and may increase the risk that we will not have sufficient quantities of such materials, product
candidates, or any medicines that we may develop and commercialize, or that such supply will not be available to us at an acceptable cost, which could
delay, prevent, or impair our development or commercialization efforts.
We do not have any manufacturing facilities. We currently rely on CDMOs for the manufacture of our materials for preclinical studies and clinical
trials and expect to continue to do so for preclinical studies, clinical trials, and for commercial supply of any product candidates that we may develop. We
currently have established relationships with several CDMOs, for the manufacture of each of our product candidates, as well as with GSK, and
76
AbbVie, for latozinemab and AL101, and for AL002, respectively. We may be unable to establish any further agreements with CDMOs or to do so on
acceptable terms. Even if we are able to establish agreements with third-party manufacturers, reliance on CDMOs entails additional risks, including:
•
•
•
•
the possible breach of the manufacturing agreement by the third party;
the possible termination or nonrenewal of the agreement by the third party at a time that is costly or inconvenient for us;
reliance on the third party for regulatory compliance, quality assurance, safety, and pharmacovigilance and related reporting; and
the inability to produce required volume in a timely manner and to quality standards.
Third-party manufacturers may not be able to comply with cGMP regulations or similar regulatory requirements outside the United States. Our
failure, or the failure of our CDMOs or collaboration partners to comply with applicable regulations could result in clinical holds on our trials, sanctions
being imposed on us, including fines, injunctions, civil penalties, delays, suspension or withdrawal of approvals, license revocations, seizures, or recalls of
product candidates or medicines, operating restrictions, and criminal prosecutions, any of which could significantly and adversely affect supplies of our
medicines and harm our business, financial condition, results of operations, and prospects.
Any medicines that we may develop may compete with other product candidates and products for access to manufacturing facilities. There are a
limited number of manufacturers that operate under cGMP regulations and that might be capable of manufacturing for us.
Any performance failure on the part of our existing or future third-party manufacturers could delay clinical development or marketing approval. If
any one of our current contract manufacturers cannot perform as agreed, we may be required to replace that manufacturer and may incur added costs and
delays in identifying and qualifying any such replacement. Furthermore, securing and reserving production capacity with contract manufacturers may result
in significant costs.
Our current and anticipated future dependence upon others for the manufacture of any product candidates we may develop or medicines may
adversely affect our future profit margins and our ability to commercialize any medicines that receive marketing approval on a timely and competitive
basis.
We, and the CDMO partners on which we rely, depend on third-party suppliers for key raw materials used in our manufacturing processes, and the loss
of these third-party suppliers or their inability to supply us with adequate raw materials, whether due to the effects of the COVID-19 pandemic or
otherwise, could harm our business.
We and the CDMO partners on which we rely depend on third-party suppliers for the supply of the raw materials required for the production of our
product candidates, and we expect to continue to depend on third-party manufacturers for the commercial supply of any of our product candidates for
which we obtain marketing approval. The dependence on these third-party suppliers and the challenges faced in obtaining adequate supplies of raw
materials involve several risks, including supply chain issues caused by the effects of the COVID-19 pandemic, limited control over pricing, the availability
of such materials, the quality of such materials, and delivery schedules. As a small company, our negotiation leverage is limited, and we are likely to get
lower priority than our competitors who are larger than we are. We do not have long-term supply agreements, and we purchase our required drug product
on a development manufacturing services agreement or purchase order basis. We cannot be certain that the suppliers will continue to provide the quantities
of these raw materials that are required or satisfy the anticipated specifications and quality requirements. Any supply interruption in limited or sole sourced
raw materials, including those caused by the effects of the COVID-19 pandemic and subsequent variants could materially harm our ability to manufacture
our product candidates until a new source of supply, if any, can be identified and qualified. In such an event, we may be unable to find a sufficient
alternative supply channel in a reasonable time or on commercially reasonable terms. Any performance failure on the part of the suppliers could delay the
development and potential commercialization of our product candidates, including limiting supplies necessary for clinical trials and regulatory approvals,
which would have a material adverse effect on our business.
77
Risks Related to Our Intellectual Property
If we are unable to obtain and maintain patent protection for any product candidates we develop, our competitors could develop and commercialize
products similar or identical to ours, and our ability to successfully commercialize any product candidates we may develop may be adversely affected.
Our success depends in large part on our ability to obtain and maintain patent protection in the United States and other countries with respect to our
proprietary product candidates and other technologies we may develop. We seek to protect our proprietary position by filing patent applications in the
United States and abroad relating to our core programs and product candidates, as well as other technologies that are important to our business. As our
product candidates enter and progress through clinical development, we continue to pursue intellectual property protection with respect to certain aspects of
those product candidates. For example, we have filed or intend to file patent applications on aspects of our technology and core product candidates;
however, there can be no assurance that any such patent applications will issue as granted patents. Furthermore, in cases in which we have only filed
provisional patent applications on certain aspects of our technology and product candidates, each of those provisional patent applications is not eligible to
become an issued patent until, among other things, we file a non-provisional patent application within 12 months of the filing date of the applicable
provisional patent application. Any failure to file a non-provisional patent application within this timeline could cause us to lose the ability to obtain patent
protection for the inventions disclosed in the associated provisional patent applications. Furthermore, in some cases, we may not be able to obtain issued
claims covering compositions relating to our core programs and product candidates, as well as other technologies that are important to our business, and
instead may need to rely on filing patent applications with claims covering a method of use and/or method of manufacture for protection of such core
programs, product candidates, and other technologies. There can be no assurance that any such patent applications will issue as granted patents, and even if
they do issue, such patent claims may be insufficient to prevent third parties, such as our competitors, from utilizing our technology. Any failure to obtain
or maintain patent protection with respect to our core programs and product candidates could have a material adverse effect on our business, financial
condition, results of operations, and prospects.
If any of our patent applications, or those of our collaborators, do not issue as patents in any jurisdiction, we may not be able to compete effectively.
Changes in either the patent laws or their interpretation in the United States and other countries may diminish our ability to protect our inventions,
obtain, maintain, and enforce our intellectual property rights and, more generally, could affect the value of our intellectual property or narrow the scope of
our patents or those of our collaborators with respect to our product candidates. With respect to both our intellectual property and that of our collaborators
related to our product candidates, we cannot predict whether the patent applications we and our collaborators are currently pursuing will issue as patents in
any particular jurisdiction or whether the claims of any issued patents will provide sufficient protection from competitors or other third parties.
The patent prosecution process is expensive, time-consuming, and complex, and we or our collaborators may not be able to file, prosecute, maintain,
enforce, or license all necessary or desirable patent applications at a reasonable cost or in a timely manner. It is also possible that we will fail to identify
patentable aspects of our research and development output in time to obtain patent protection. Although we enter into nondisclosure and confidentiality
agreements with parties who have access to confidential or patentable aspects of our research and development output, such as our employees, corporate
collaborators, outside scientific collaborators, CROs, CDMOs, consultants, advisors, and other third parties, any of these parties may breach the agreements
and disclose such output before a patent application is filed, thereby jeopardizing our ability to seek patent protection. In addition, our ability to obtain and
maintain valid and enforceable patents depends on whether the differences between our inventions and the prior art allow our inventions to be patentable
over the prior art. Furthermore, publications of discoveries in the scientific literature often lag behind the actual discoveries, and patent applications in the
United States and other jurisdictions are typically not published until 18 months after filing, or in some cases not at all. Therefore, we cannot be certain that
we or our collaborators were first to file for patent protection of such inventions.
78
If the scope of any patent protection we obtain is not sufficiently broad, or if we lose any of our patent protection, our ability to prevent our competitors
from commercializing similar or identical technology and product candidates would be adversely affected.
The patent position of biotechnology and pharmaceutical companies generally is highly uncertain, involves complex legal and factual questions, and
has been the subject of much litigation in recent years. As a result, the issuance, scope, validity, enforceability, and commercial value of our patent rights
are highly uncertain. Our or our collaborators’ pending and future patent applications may not result in patents being issued which protect our product
candidates or other technologies or which effectively prevent others from commercializing competitive technologies and product candidates.
Moreover, the coverage claimed in a patent application can be significantly reduced before the patent is issued, and its scope can be reinterpreted
after issuance. Even if patent applications we or our collaborators license or own currently or in the future issue as patents, they may not issue in a form that
will provide us with any meaningful protection, prevent competitors or other third parties from competing with us, or otherwise provide us with any
competitive advantage. Any patents to which we or our collaborators have rights may be challenged, narrowed, circumvented, or invalidated by third
parties. Consequently, we do not know whether product candidates or other technologies will be protectable or remain protected by valid and enforceable
patents. Our competitors or other third parties may be able to circumvent our patents by developing similar or alternative technologies or products in a non-
infringing manner which could materially adversely affect our business, financial condition, results of operations and prospects.
The issuance of a patent is not conclusive as to its inventorship, scope, validity, or enforceability, and our patents may be challenged in the courts or
patent offices in the United States and abroad. We or our collaborators may be subject to a third-party pre-issuance submission of prior art to the United
States Patent and Trademark Office (USPTO) or foreign patent offices or become involved in opposition, derivation, revocation, reexamination, post-grant
and inter partes review, inventorship dispute, or interference proceedings or other similar proceedings challenging our or our collaborators’ patent rights.
An adverse determination in any such submission, proceeding, or litigation could reduce the scope of, or invalidate or render unenforceable, such patent
rights, allow third parties to commercialize our product candidates or other technologies and compete directly with us, without payment to us. Moreover,
we, or any one of our collaborators, may have to participate in post-grant challenge proceedings, such as oppositions in a foreign patent office, in which a
third party challenges the features of patentability with respect to our or our collaborators’ patents and patent applications. Such challenges may result in
loss of patent rights, loss of exclusivity, or in patent claims being narrowed, invalidated, or held unenforceable, which could limit our ability to stop others
from using or commercializing similar or identical technology and products, or limit the duration of the patent protection for our product candidates and
other technologies. Such proceedings also may result in substantial cost and require significant time from our scientists and management, even if the
eventual outcome is favorable to us. If we or our collaborators are unsuccessful in any such proceeding or other inventorship dispute, we may be required
to obtain and maintain licenses from third parties. Such licenses may not be available on commercially reasonable terms or at all, or may be non-exclusive.
If we are unable to obtain and maintain such licenses, we may need to cease the development, manufacture, and commercialization of one or more of the
product candidates we may develop. The loss of exclusivity or the narrowing of our owned and licensed patent claims could limit our ability to stop others
from using or commercializing similar or identical technology and products.
In addition, given the amount of time required for the development, testing, and regulatory review of new product candidates, patents protecting
such product candidates might expire before or shortly after such product candidates are commercialized. As a result, our intellectual property may not
provide us with rights to exclude others for sufficient period of time from commercializing products similar or identical to ours.
Some of our patents and patent applications may be co-owned with third parties. In addition, collaborators or future licensors may co-own their
patents and patent applications with other third parties with whom we do not have a direct relationship. Our rights to certain of these patents and patent
applications may be dependent, in part, on inter-institutional or other operating agreements between the joint owners of such patents and patent
applications, who are not parties to our license agreements. If our collaborators or future licensors do not have exclusive control of the grant of licenses
under any such third-party co-owners’ interest in such patents or patent applications or we are otherwise unable to secure such exclusive rights, such co-
owners may be able to license their rights to other third parties, including our competitors, and our competitors could market competing products and
technology to the extent such products and technology are not also covered by our intellectual property. In addition, we may need the
79
cooperation of any such co-owners of our patents in order to enforce such patents against third parties, and such cooperation may not be provided to us.
Any of the foregoing could have a material adverse effect on our competitive position, business, financial conditions, results of operations, and prospects.
Our rights to develop and commercialize are subject, in part, to the terms and conditions of agreements with others, including terms and conditions
regarding intellectual property rights.
We rely on certain patent rights and proprietary technology from third parties that are important or necessary to the development of our product
candidates, and development and commercialization of our product candidates are subject to the terms and conditions of certain collaboration agreements
with third parties. For example, in 2014 we entered into the Adimab Collaboration Agreement with Adimab. Under the 2014 Adimab Collaboration
Agreement, we are developing antibodies discovered by Adimab in our latozinemab and AL101 product candidates, and we are developing an antibody
optimized by Adimab in our AL002 product candidate. In August 2019, we entered into a new collaboration agreement with Adimab for development of
antibodies for use in future programs. In 2021, we entered into another collaboration agreement with Adimab, which grants us an exclusive option to obtain
a specified number of engineered sequences. discovered or optimized by Adimab and directed against targets that we select. Additionally, in October 2017,
we entered into an agreement with AbbVie to co-develop and commercialize medicines with AbbVie to treat Alzheimer’s disease and other
neurodegenerative diseases. In July 2021, we entered into the GSK Agreement to collaborate on the global development and commercialization of the
progranulin-elevating monoclonal antibodies, latozinemab and AL101.
Our agreements with Adimab, AbbVie, GSK, and other agreements we enter into in the future may not provide exclusive rights to use certain
intellectual property and technology retained by the collaborator in all relevant fields of use and in all territories in which we may wish to develop or
commercialize our technology and products in the future. As a result, we may not be able to prevent competitors or other third parties from developing and
commercializing competitive products that utilize technology retained by such collaborators to the extent such products are not also covered by our
intellectual property.
In addition, subject to the terms of any such agreements, we may not have the right to control the preparation, filing, prosecution, and maintenance,
and we may not have the right to control the enforcement and defense of certain patents and patent applications relating to or affecting our development
candidates. In addition, the GSK Agreement provides GSK with certain rights with respect to preparation, filing, prosecution, maintenance, enforcement,
and defense of certain patents and patent applications.
We cannot be certain that patents and patent applications as to which preparation, filing, prosecution, maintenance, enforcement, or defense are
controlled by our collaborators will be prepared, filed, prosecuted, maintained, enforced, and defended in a manner consistent with the best interests of our
business. If our collaborators fail to prosecute, maintain, enforce, and defend such patents, or lose rights to those patents or patent applications, our rights as
to such patents may be reduced or eliminated, our right to develop and commercialize any of our product candidates that are subject of such rights could be
adversely affected, and we may have a reduced ability to prevent competitors from making, using, and selling competing products. In addition, even where
we have the right to control prosecution of patent applications we have licensed to and from collaborators, we may still be adversely affected or prejudiced
by actions or inactions of our collaborators that took place prior to the date upon which we assumed control over patent prosecution.
Furthermore, our or our collaborators’ patents may be subject to a reservation of rights by one or more third parties. For example, we received an
award from the National Institute of Health in support of our research into the production and characterization of novel therapeutic antibodies against the
neurotrophic factor PGRN degrading receptor SORT1. As a result, the U.S. government may have certain rights to resulting intellectual property. When
new technologies are developed with U.S. government funding, the U.S. government generally obtains certain rights in any resulting patents, including a
non-exclusive license authorizing the U.S. government to use the invention or to have others use the invention on its behalf. The U.S. government’s rights
may also permit it to disclose the funded inventions and technology to third parties and to exercise march-in rights to use or allow third parties to use the
technology developed using U.S. government funding. The U.S. government may exercise its march-in rights if it determines that action is necessary
because we fail to achieve the practical application of the government funded technology, or because action is necessary to alleviate health or safety needs,
to meet requirements of federal regulations, or to give preference to U.S. industry. In addition, our rights in such inventions may be subject to certain
requirements to manufacture products embodying such inventions in facilities in the United States in certain
80
circumstances and if this requirement is not waived. Any exercise by the U.S. government of such rights or by any third party of its reserved rights could
have a material adverse effect on our competitive position, business, financial condition, results of operations, and prospects.
If we fail to comply with our obligations in the agreements under which we option or license intellectual property rights from our collaborators or
future licensors or otherwise experience disruptions to our business relationships with our collaborators or future licensors, we could lose intellectual
property rights that are important to our business.
We have entered into agreements with our collaborators to option or license certain intellectual property and may need to obtain additional
intellectual property rights from others to advance our research or allow commercialization of product candidates we may develop. It is possible that we
may be unable to obtain additional intellectual property rights at a reasonable cost or on reasonable terms, if at all. In that event, we may be required to
expend significant time and resources to redesign our technology, product candidates, or the methods for manufacturing them or to develop or license
replacement technology, all of which may not be feasible on a technical or commercial basis. If we are unable to do so, we may be unable to develop or
commercialize the affected product candidates, which could harm our business, financial condition, results of operations, and prospects significantly. We
cannot provide any assurances that third-party patents do not exist which might be enforced against our current technology, manufacturing methods,
product candidates, or future methods or products resulting in either an injunction prohibiting our manufacture or future sales, or, with respect to our future
sales, an obligation on our part to pay royalties and/or other forms of compensation to third parties, which could be significant.
In addition, each of our agreements with collaborators do, and we expect our future agreements will, impose various economic, development,
diligence, commercialization, and other obligations on us. Certain of our collaboration agreements also require us to meet development timelines, or to
exercise commercially reasonable efforts to develop and commercialize licensed products. In spite of our efforts, our collaborators might conclude that we
have materially breached our obligations under such agreements and might therefore terminate or seek damages under the agreements, thereby removing or
limiting our ability to develop and commercialize products and technology covered by these agreements. If termination of these agreements causes us to
lose the rights to certain patents or other intellectual property, or if the underlying patents fail to provide the intended exclusivity, competitors or other third
parties may have the freedom to seek regulatory approval of, and to market, products similar to or identical to ours and we may be required to cease our
development and commercialization of certain of our product candidates. Any of the foregoing could have a material adverse effect on our competitive
position, business, financial conditions, results of operations, and growth prospects.
Moreover, disputes may arise regarding intellectual property subject to a collaboration agreement, including:
•
•
•
•
•
the scope of the option or license rights granted under the agreement and other interpretation-related issues;
the extent to which our technology and processes infringe on intellectual property of the collaborator that is not subject to the option or
license rights granted under the agreement;
the sublicensing of patent and other rights under our collaborative development relationships;
our diligence obligations under the agreement and what activities satisfy those diligence obligations; and
the inventorship and ownership of inventions and know-how resulting from the joint creation or use of intellectual property by our
collaborators and us and our other partners.
In addition, the agreements under which we currently have rights to option or license intellectual property or technology from third parties are
complex, and certain provisions in such agreements may be susceptible to multiple interpretations. The resolution of any contract interpretation
disagreement that may arise could narrow what we believe to be the scope of our rights to the relevant intellectual property or technology, or increase what
we believe to be our financial or other obligations under the relevant agreement, either of which could have a material adverse effect on our business,
financial condition, results of operations, and growth prospects. Moreover, if disputes over intellectual property that we have optioned or licensed prevent
or impair our ability to maintain our current arrangements on commercially acceptable terms, we may be unable to successfully develop and commercialize
the
81
affected product candidates, which could have a material adverse effect on our business, financial conditions, results of operations, and growth prospects.
We may not be able to protect our intellectual property and proprietary rights throughout the world.
Filing, prosecuting, and defending patents on our product candidates and other technologies in all countries throughout the world would be
prohibitively expensive, and the laws of foreign countries may not protect our rights to the same extent as the laws of the United States.
Consequently, we may not be able to prevent third parties from practicing our inventions in all countries outside the United States, or from selling or
importing products made using our inventions in or into the United States or other jurisdictions. Competitors may use our technologies in jurisdictions
where we have not obtained patent protection to develop their own products, and, further, may export otherwise infringing products to territories where we
have patent protection but enforcement is not as strong as that in the United States. These products may compete with our products, and our patents or other
intellectual property rights may not be effective or sufficient to prevent them from competing.
Many companies have encountered significant problems in protecting and defending intellectual property rights in foreign jurisdictions. The legal
systems of certain countries, particularly certain developing countries, do not favor the enforcement of patents, trade secrets, and other intellectual property
protection, particularly those relating to biotechnology products, which could make it difficult for us to stop the infringement of our patents or marketing of
competing products in violation of our intellectual property and proprietary rights generally. Proceedings to enforce our intellectual property and
proprietary rights in foreign jurisdictions could result in substantial costs and divert our efforts and attention from other aspects of our business, could put
our patents at risk of being invalidated or interpreted narrowly, could put our patent applications at risk of not issuing, and could provoke third parties to
assert counterclaims against us. We may not prevail in any lawsuits that we initiate, and the damages or other remedies awarded, if any, may not be
commercially meaningful. Accordingly, our efforts to enforce our intellectual property and proprietary rights around the world may be inadequate to obtain
a significant commercial advantage from the intellectual property that we develop or license.
Many countries have compulsory licensing laws under which a patent owner may be compelled to grant licenses to third parties. In addition, many
countries limit the enforceability of patents against government agencies or government contractors. In these countries, the patent owner may have limited
remedies, which could materially diminish the value of such patents. If we, our collaborators or any of our future licensors is forced to grant a license to
third parties with respect to any patents relevant to our business, our competitive position may be impaired, and our business, financial condition, results of
operations, and prospects may be adversely affected.
Obtaining and maintaining our patent protection depends on compliance with various procedural, document submission, fee payment, and other
requirements imposed by government patent agencies, and our patent protection could be reduced or eliminated for non-compliance with these
requirements.
Periodic maintenance fees, renewal fees, annuity fees, and various other government fees on patents and applications will be due to the USPTO and
various government patent agencies outside of the United States over the lifetime of our owned or licensed patents and applications. In certain
circumstances, we rely on our collaborators or licensing partners to pay these fees due to U.S. and non-U.S. patent agencies. The USPTO and various non-
U.S. government agencies require compliance with several procedural, documentary, fee payment, and other similar provisions during the patent
application process. We also are dependent on our collaborators or licensors to take the necessary action to comply with these requirements with respect to
our licensed intellectual property. In some cases, an inadvertent lapse can be cured by payment of a late fee or by other means in accordance with the
applicable rules. There are situations, however, in which non-compliance can result in abandonment or lapse of the patent or patent application, resulting in
a partial or complete loss of patent rights in the relevant jurisdiction. In such an event, potential competitors might be able to enter the market with similar
or identical products or technology, which could have a material adverse effect on our business, financial condition, results of operations, and growth
prospects.
The ongoing conflict between Russia and Ukraine, including the sanctions targeting Russia, could interfere with filing of patent applications,
prosecution of applications, and maintenance of issued patents in Russia, Ukraine, and via the Eurasian Patent Office. For example, the conflict and
sanctions could interfere with payment of filing fees, extension fees, and annuities. The conflict and sanctions could also interfere with enforcement or
defense of patents issued in Russia, Ukraine, and via the Eurasian Patent Office. The conflict and associated sanctions could
82
therefore increase the uncertainties and costs surrounding the prosecution of our patent applications and the enforcement or defense of any future issued
patents, all of which could have a material adverse effect on our business, financial condition, results of operations, and prospects.
Changes in U.S. patent law could diminish the value of patents in general, thereby impairing our ability to protect our products.
Changes in either the patent laws or interpretation of the patent laws in the United States could increase the uncertainties and costs surrounding the
prosecution of patent applications and the enforcement or defense of issued patents. For example, under the Leahy-Smith America Invents Act (the
America Invents Act), the first inventor to file a patent application in the United States is entitled to the patent on an invention regardless of whether
another party was the first to invent the claimed invention. Therefore, a third party that filed a patent application in the USPTO after March 2013, but
before us, could be awarded a patent covering an invention of ours even if we had made the invention before it was made by such third party. This
possibility requires us to be cognizant of the time from invention to the time of filing a patent application. Because patent applications in the United States
and most other countries are confidential for a period of time after filing or until issuance, we cannot be certain that we were the first to file any patent
application related to our product candidates or other technologies.
Certain procedures at the USPTO under the America Invents Act could affect the way patent applications are prosecuted and also may affect patent
litigation. These include allowing third party submission of prior art to the USPTO during patent prosecution and additional procedures to attack the
validity of a patent by USPTO administered post-grant proceedings, including post-grant review, inter partes review, and derivation proceedings. Because
of a lower evidentiary standard in USPTO proceedings compared to the evidentiary standard in United States federal courts necessary to invalidate a patent
claim, a third party could potentially provide evidence in a USPTO proceeding sufficient for the USPTO to hold a claim invalid even though the same
evidence would be insufficient to invalidate the claim if presented in a district court action. Accordingly, a third party may attempt to use the USPTO
procedures to invalidate our patent claims that would not have been invalidated if challenged by the third party as a defendant in a district court action.
Therefore, the America Invents Act and its implementation could increase the uncertainties and costs surrounding the prosecution of our patent applications
and the enforcement or defense of our issued patents, all of which could have a material adverse effect on our business, financial condition, results of
operations, and prospects.
In addition, the patent positions of companies in the development and commercialization of pharmaceuticals are particularly uncertain. Rulings from
the U.S. Supreme Court and the U.S. Court of Appeals for the Federal Circuit have narrowed the scope of patent protection available in certain
circumstances and weakened the rights of patent owners in certain situations. This combination of events has created uncertainty with respect to the validity
and enforceability of patents, once obtained. Depending on future actions by the U.S. Congress, the federal courts, and the USPTO, the laws and
regulations governing patents could change in unpredictable ways that could have a material adverse effect on our existing patent portfolio and our ability
to protect and enforce our intellectual property in the future.
Issued patents covering our product candidates and other technologies could be found invalid or unenforceable if challenged in court or before
administrative bodies in the United States or abroad.
If we initiated legal proceedings against a third party to enforce a patent covering our product candidates or other technologies, the defendant could
counterclaim that such patent is invalid or unenforceable. In patent litigation in the United States, defendant counterclaims alleging invalidity or
unenforceability are commonplace. Grounds for a validity challenge could be an alleged failure to meet any of several statutory requirements, including
lack of novelty, obviousness, written description, or enablement. Grounds for an unenforceability assertion could be an allegation that someone connected
with prosecution of the patent withheld relevant information from the USPTO, or made a misleading statement, during prosecution. Third parties may raise
claims challenging the validity or enforceability of our patents before administrative bodies in the United States or abroad, even outside the context of
litigation. Such mechanisms include re-examination, post-grant review, inter partes review, derivation proceedings, and equivalent proceedings in foreign
jurisdictions (e.g., opposition proceedings). Such proceedings could result in the revocation of, cancellation of, or amendment to our patents in such a way
that they no longer cover our product candidates or other technologies. The outcome following legal assertions of invalidity and unenforceability is
unpredictable. With respect to the validity question, for example, we cannot be certain that there is no invalidating prior art, of which we or our licensing
partners and the patent examiner were unaware during prosecution. If a third
83
party were to prevail on a legal assertion of invalidity or unenforceability, we would lose at least part, and perhaps all, of the patent protection on our
product candidates or other technologies. Such a loss of patent protection would have a material adverse impact on our business, financial condition, results
of operations, and growth prospects.
If we do not obtain patent term extension and data exclusivity for any product candidates we may develop, our business may be materially harmed.
Depending upon the timing, duration, and specifics of any FDA marketing approval of any product candidates we may develop, one or more of our
U.S. patents may be eligible for limited patent term extension under the Hatch-Waxman Act. The Hatch-Waxman Act permits a patent term extension of up
to five years as compensation for patent term lost during the FDA regulatory review process. A patent term extension cannot extend the remaining term of a
patent beyond a total of 14 years from the date of product approval, only one patent may be extended and only those claims covering the approved drug, a
method for using it, or a method for manufacturing it may be extended. Similar extensions as compensation for patent term lost during regulatory review
processes are also available in certain foreign countries and territories, such as in Europe under a Supplementary Protection Certificate. However, we may
not be granted an extension in the United States and/or foreign countries and territories because of, for example, failing to exercise due diligence during the
testing phase or regulatory review process, failing to apply within applicable deadlines, failing to apply prior to expiration of relevant patents, or otherwise
failing to satisfy applicable requirements. Moreover, the applicable time period or the scope of patent protection afforded could be less than we request. If
we are unable to obtain patent term extension or the term of any such extension is shorter than what we request, our competitors may obtain approval of
competing products following our patent expiration, and our business, financial condition, results of operations, and growth prospects could be materially
harmed.
We may be subject to claims challenging the inventorship of our patents and other intellectual property.
We may be subject to claims that former employees, collaborators or other third parties have an interest in our patents, trade secrets, or other
intellectual property as an inventor or co-inventor. For example, we may have inventorship disputes arise from conflicting obligations of employees,
consultants, or others who are involved in developing our product candidates or other technologies. Litigation may be necessary to defend against these and
other claims challenging inventorship or ownership of our patents, trade secrets, or other intellectual property. If the defense of any such claims fails, in
addition to paying monetary damages, we may lose valuable intellectual property rights, such as exclusive ownership of, or right to use, intellectual
property that is important to our product candidates and other technologies. Even if we are successful in defending against such claims, litigation could
result in substantial costs and be a distraction to management and other employees. Any of the foregoing could have a material adverse effect on our
business, financial condition, results of operations, and growth prospects.
If we are unable to protect the confidentiality of our trade secrets, our business and competitive position would be harmed.
In addition to seeking patents for our product candidates and other technologies, we also rely on trade secrets and confidentiality agreements to
protect our unpatented know-how, technology, and other proprietary information and to maintain our competitive position. We consider trade secrets and
know-how to be one of our primary sources of intellectual property. Trade secrets and know-how can be difficult to protect. We expect our trade secrets and
know-how to over time be disseminated within the industry through independent development, the publication of journal articles describing the
methodology, and the movement of personnel from academic to industry scientific positions.
We seek to protect these trade secrets and other proprietary technology, in part, by entering into non-disclosure and confidentiality agreements with
parties who have access to them, such as our employees, corporate and academic collaborators, outside scientific collaborators, CROs, CDMOs,
consultants, advisors, and other third parties. We also enter into confidentiality and invention or patent assignment agreements with our employees and
consultants, train our employees not to bring or use proprietary information or technology from former employers to us or in their work, and remind former
employees when they leave their employment of their confidentiality obligations. We cannot guarantee that we have entered into such agreements with
each party that may have or have had access to our trade secrets or proprietary technology and processes. Despite our efforts, any of these parties may
breach the agreements and disclose our proprietary information, including our trade secrets, and we may not be able
84
to obtain adequate remedies for such breaches. In addition, some courts inside and outside the United States are less willing or unwilling to protect trade
secrets. If any of our trade secrets were to be lawfully obtained or independently developed by a competitor or other third party, we would have no right to
prevent them from using that technology or information to compete with us. If any of our trade secrets were to be disclosed to or independently developed
by a competitor or other third party, our competitive position would be materially and adversely harmed.
We may not be successful in obtaining, through acquisitions or otherwise, necessary rights to our product candidates or other technologies.
Many pharmaceutical companies, biotechnology companies, and academic institutions that are competing with us in the field of neurodegeneration
therapy may have patents and have filed and are likely filing patent applications potentially relevant to our business. In order to avoid infringing these
third-party patents, we may find it necessary or prudent to obtain licenses to such patents from such third-party intellectual property holders. We may also
require licenses from third parties for certain technologies for use with future product candidates. In addition, with respect to any patents we co-own with
third parties, we may wish to obtain licenses to such co-owners’ interest to such patents. However, we may be unable to secure such licenses or otherwise
acquire any rights to compositions, methods of use, processes, or other intellectual property rights from third parties that we identify as necessary for our
future product candidates. The licensing or acquisition of third-party intellectual property rights is a competitive area, and more established companies may
pursue strategies to license or acquire third-party intellectual property rights that we may consider attractive or necessary. These established companies may
have a competitive advantage over us due to their size, capital resources, and greater clinical development and commercialization capabilities. In addition,
companies that perceive us to be a competitor may be unwilling to assign or license rights to us. We also may be unable to license or acquire third-party
intellectual property rights on terms that would allow us to make an appropriate return on our investment or at all. If we are unable to successfully obtain
rights to required third-party intellectual property rights or maintain the existing intellectual property rights we have, we may have to abandon development
of the relevant program or product candidate, which could have a material adverse effect on our business, financial condition, results of operations, and
growth prospects.
We may be subject to claims that our employees, consultants, or advisors have wrongfully used or disclosed alleged trade secrets of their current or
former employers or claims asserting ownership of what we regard as our own intellectual property.
Many of our employees, consultants, and advisors are currently or were previously employed at universities or other biotechnology or
pharmaceutical companies, including our competitors and potential competitors. Although we try to ensure that our employees, consultants, and advisors
do not use the proprietary information or know-how of others in their work for us, we may be subject to claims that we or these individuals have used or
disclosed intellectual property, including trade secrets or other proprietary information, of any such individual’s current or former employer. Litigation may
be necessary to defend against these claims. If we fail in defending any such claims, in addition to paying monetary damages, we may lose valuable
intellectual property rights or personnel. Even if we are successful in defending against such claims, litigation could result in substantial costs and be a
distraction to management.
In addition, while it is our policy to require our employees and contractors who may be involved in the conception or development of intellectual
property to execute agreements assigning such intellectual property to us, we may be unsuccessful in executing such an agreement with each party who, in
fact, conceives or develops intellectual property that we regard as our own. The assignment of intellectual property rights may not be self-executing, or the
assignment agreements may be breached, and we may be forced to bring claims against third parties, or defend claims that they may bring against us, to
determine the ownership of what we regard as our intellectual property. Such claims could have a material adverse effect on our business, financial
condition, results of operations, and growth prospects.
Third-party claims of intellectual property infringement, misappropriation, or other violation against us or our collaborators may prevent or delay the
development and commercialization of our product candidates and other technologies.
The field of discovering treatments for neurodegenerative diseases is highly competitive and dynamic. Due to the focused research and development
that is taking place by various companies, including us and our competitors, in this field, the intellectual property landscape is in flux, and it may remain
uncertain in the future. Additionally, the
85
technology used in our product candidates is still in development and no products utilizing similar technology have yet reached the market. As such, there
may be significant intellectual property related litigation and proceedings relating to our, and other third party, intellectual property and proprietary rights in
the future.
Our commercial success depends in part on our and our collaborators’ ability to develop, manufacture, market, and sell any product candidates that
we develop and to use our proprietary technologies without infringing, misappropriating, and otherwise violating the patents and other intellectual property
rights of third parties. There is a substantial amount of complex litigation involving patents and other intellectual property rights in the biotechnology and
pharmaceutical industries, and we may become subject to, or threatened with, such actions in the future, regardless of their merit. In addition, we may
undertake costly administrative proceedings for challenging third party patents, including post-grant, derivation, and reexamination proceedings before the
USPTO or oppositions and other comparable proceedings in foreign jurisdictions.
Numerous U.S. and foreign issued patents and pending patent applications owned by third parties exist in the fields in which we are developing our
product candidates. As the biotechnology and pharmaceutical industries expand and more patents are issued, the risk increases that our product candidates
and other technologies may give rise to claims of infringement of the patent rights of others. We cannot be assured that our product candidates and other
technologies that we have developed, are developing, or may develop in the future will not infringe existing or future patents owned by third parties. We
may not be aware of patents that have already been issued and that a third party, for example, a competitor in the fields in which we are developing product
candidates, and other technologies might assert are infringed by our current or future product candidates or other technologies, including claims to
compositions, formulations, methods of manufacture or methods of use or treatment that cover our product candidates or other technologies. It is also
possible that patents owned by third parties of which we are aware, but which we do not believe are relevant to our product candidates or other
technologies, could be found to be infringed by our product candidates or other technologies. In addition, because patent applications can take many years
to issue, there may be currently pending patent applications that may later result in issued patents that our product candidates or other technologies may
infringe.
Third parties may have patents or obtain patents in the future and claim that the manufacture, use or sale of our product candidates or other
technologies infringes upon these patents. In the event that any third-party claims that we infringe their patents or that we are otherwise employing their
proprietary technology without authorization and initiates litigation against us, even if we believe such claims are without merit, a court of competent
jurisdiction could hold that such patents are valid, enforceable, and infringed by our product candidates or other technologies. In this case, the holders of
such patents may be able to block our ability to manufacture or commercialize the applicable product candidate or technology unless we obtain a license
under the applicable patents, or until such patents expire or are finally determined to be held invalid or unenforceable. Such a license may not be available
on commercially reasonable terms or at all. Even if we are able to obtain a license, the license would likely obligate us to pay license fees or royalties or
both, and the rights granted to us might be nonexclusive, which could result in our competitors gaining access to the same intellectual property. If we are
unable to obtain a necessary license to a third-party patent on commercially reasonable terms, we may be unable to commercialize our product candidates
or other technologies, or such commercialization efforts may be significantly delayed, which could in turn significantly harm our business.
Defense of infringement claims, regardless of their merit, would involve substantial litigation expense and would be a substantial diversion of
management and other employee resources from our business, and may impact our reputation. In the event of a successful claim of infringement against us,
we may be enjoined from further developing or commercializing our infringing product candidates or other technologies. In addition, we may have to pay
substantial damages, including treble damages and attorneys’ fees for willful infringement, obtain one or more licenses from third parties, pay royalties,
and/or redesign our infringing product candidates or technologies, which may be impossible or require substantial time and monetary expenditure. In that
event, we would be unable to further develop and commercialize our product candidates or other technologies, which could harm our business significantly.
Engaging in litigation to defend against third parties alleging that we have infringed, misappropriated, or otherwise violated their patents or other
intellectual property rights is very expensive, particularly for a company of our size, and time-consuming. Some of our competitors may be able to sustain
the costs of litigation or administrative proceedings more effectively than we can because of greater financial resources. Patent litigation and other
proceedings may also absorb significant management time. Uncertainties resulting from the initiation and
86
continuation of patent litigation or other proceedings against us could impair our ability to compete in the marketplace. The occurrence of any of the
foregoing could have a material adverse effect on our business, financial condition, results of operations, and growth prospects.
We may become involved in lawsuits to protect or enforce our patents and other intellectual property rights, or to defend against allegations of patent
infringement, which could be expensive, time consuming, and unsuccessful.
Competitors may infringe our patents or the patents of our licensing partners, or we may be required to defend against claims of infringement. In
addition, our patents or the patents of our licensing partners also may become involved in inventorship, or validity disputes. To counter or defend against
such claims can be expensive and time consuming. In an infringement proceeding, a court may decide that a patent in which we have an interest is invalid
or unenforceable, the other party’s use of our patented technology falls under the safe harbor to patent infringement under 35 U.S.C. §271(e)(1), or may
refuse to stop the other party from using the technology at issue on the grounds that our patents do not cover the technology in question. An adverse result
in any litigation proceeding could put one or more of our patents at risk of being invalidated or interpreted narrowly. Furthermore, because of the
substantial amount of discovery required in connection with intellectual property litigation, there is a risk that some of our confidential information could
be compromised by disclosure during this type of litigation.
Even if resolved in our favor, litigation or other legal proceedings relating to intellectual property claims may cause us to incur significant expenses
and could distract our personnel from their normal responsibilities. In addition, there could be public announcements of the results of hearings, motions, or
other interim proceedings or developments, and if securities analysts or investors perceive these results to be negative, it could have a substantial adverse
effect on the price of our common stock. Such litigation or proceedings could substantially increase our operating losses and reduce the resources available
for development activities or any future sales, marketing, or distribution activities. We may not have sufficient financial or other resources to conduct such
litigation or proceedings adequately. Some of our competitors may be able to sustain the costs of such litigation or proceedings more effectively than we
can because of their greater financial resources and more mature and developed intellectual property portfolios. Uncertainties resulting from the initiation
and continuation of patent litigation or other proceedings could have a material adverse effect on our ability to compete in the marketplace.
If our trademarks and trade names are not adequately protected, then we may not be able to build name recognition in our markets of interest and our
business may be adversely affected.
Our registered or unregistered trademarks or trade names may be challenged, infringed, circumvented, or declared generic or determined to be
infringing on other marks. We may not be able to protect our rights to these trademarks and trade names, which we need to build name recognition among
potential partners or customers in our markets of interest. At times, competitors or other third parties may adopt trade names or trademarks similar to ours,
thereby impeding our ability to build brand identity and possibly leading to market confusion. In addition, there could be potential trade name or trademark
infringement claims brought by owners of other registered trademarks or trademarks that incorporate variations of our registered or unregistered trademarks
or trade names. Over the long term, if we are unable to establish name recognition based on our trademarks and trade names, then we may not be able to
compete effectively and our business may be adversely affected. Our efforts to enforce or protect our proprietary rights related to trademarks, trade secrets,
domain names, copyrights or other intellectual property may be ineffective and could result in substantial costs and diversion of resources and could
adversely affect our business, financial condition, results of operations, and growth prospects.
Intellectual property rights do not necessarily address all potential threats.
The degree of future protection afforded by our intellectual property rights is uncertain because intellectual property rights have limitations and may
not adequately protect our business or permit us to maintain our competitive advantage. For example:
•
•
others may be able to make products that are similar to our product candidates or utilize similar technology but that are not covered by the
claims of the patents that we license or may own;
our future licensors or collaborators, might not have been the first to invent the claimed inventions covered by the issued patents or pending
patent applications that we license in the future;
87
•
•
•
•
•
•
•
•
we, or our current or future licensors or collaborators, might not have been the first to file patent applications covering certain of our or
their inventions;
others may independently develop similar or alternative technologies or duplicate any of our technologies without infringing our owned or
licensed intellectual property rights;
it is possible that our current or future pending owned or licensed patent applications will not lead to issued patents;
issued patents that we hold rights to may be held invalid or unenforceable, including as a result of legal challenges by our competitors or
other third parties;
our competitors or other third parties might conduct research and development activities in countries where we do not have patent rights
and then use the information learned from such activities to develop competitive products for sale in our major commercial markets;
we may not develop additional proprietary technologies that are patentable;
the patents of others may harm our business; and
we may choose not to file a patent application in order to maintain certain trade secrets or know-how, and a third party may subsequently
file a patent application covering such intellectual property.
Should any of these events occur, they could have a material adverse effect on our business, financial condition, results of operations, and growth
prospects.
Risks Related to Our Operations
We are highly dependent on our key personnel, and if we are not successful in attracting, motivating, and retaining highly qualified personnel,
especially in light of a competitive hiring and compensation environment, we may not be able to successfully implement our business strategy.
Our ability to compete in the highly competitive biotechnology and pharmaceutical industries depends upon our ability to attract, motivate, and
retain highly qualified managerial, scientific, and medical personnel. We are highly dependent on our leadership, including our Chief Executive Officer, Dr.
Arnon Rosenthal. The loss of the services provided by any of our executive officers, other key employees, and other scientific and medical advisors, and
our inability to either find suitable replacements in the event of such loss or to attract senior management personnel to fill open positions, especially in light
of a highly competitive hiring and wage environment, could result in delays in the development of our product candidates and harm our business.
We conduct our operations at our facility in South San Francisco, California, in a region that is headquarters to many other biopharmaceutical
companies and many academic and research institutions. Competition for skilled personnel is intense and the turnover rate can be high, especially in light
of recent competitive hiring and wage environment, which may limit our ability to hire and retain highly qualified personnel on acceptable terms or at all.
We expect that we may need to recruit talent from outside of our region and doing so may be costly and difficult.
To induce valuable employees to remain at our company, in addition to salary and cash incentives, we have provided and will continue to provide
restricted stock, stock option grants, and other equity awards that vest over time. The value to employees of these equity grants that vest over time may be
significantly affected by movements in our stock price that are beyond our control and may at any time be insufficient to counteract more lucrative offers
from other companies. Although we have employment agreements with our key employees, these employment agreements provide for at-will employment,
which means that any of our employees could leave our employment at any time, with or without notice. If we are unable to attract and incentivize quality
personnel on acceptable terms, or at all, it may cause our business and operating results to suffer.
We will need to effectively manage the size and capabilities of our organization.
As of December 31, 2022, we had 273 full-time employees. As our development plans and strategies develop, we will be required to add additional
managerial, operational, financial, and other personnel. We will need to
88
effectively manage the size and capabilities of our organization and any future growth through significant responsibilities on members of management,
including:
•
•
•
•
identifying, recruiting, integrating, retaining, and motivating additional employees;
managing our internal development efforts effectively, including the clinical and FDA review process for our current and future product
candidates, while complying with our contractual obligations to collaborators and other third parties;
expanding our operational, financial and management controls, reporting systems, and procedures; and
managing increasing operational and managerial complexity.
Our future financial performance and our ability to continue to develop and, if approved, commercialize our product candidates will depend, in part,
on our ability to effectively manage any future growth. Our management may also have to divert a disproportionate amount of its attention away from day-
to-day activities in order to manage these growth activities.
We currently rely, and for the foreseeable future will continue to rely, in substantial part on certain independent organizations, advisors, and
consultants to provide certain services. There can be no assurance that the services of these independent organizations, advisors, and consultants will
continue to be available to us on a timely basis when needed, or that we can find qualified replacements. In addition, if we are unable to effectively manage
our outsourced activities or if the quality or accuracy of the services provided by consultants is compromised for any reason, our clinical trials may be
extended, delayed, or terminated, and we may not be able to obtain regulatory approval of our product candidates or otherwise advance our business. There
can be no assurance that we will be able to manage our existing consultants or find other competent outside contractors and consultants on economically
reasonable terms, if at all.
If we are not able to effectively expand our organization by hiring new employees and expanding our groups of consultants and contractors, we may
not be able to successfully implement the tasks necessary to further develop our product candidates, our clinical trials may be extended, delayed, or
terminated, and we may not be able to obtain regulatory approval of our product candidates, and accordingly, may not achieve our research, development,
and commercialization goals.
We have engaged in strategic collaborations and may in the future engage in acquisitions, collaborations, or strategic partnerships, which may increase
our capital requirements, dilute our stockholders, cause us to incur debt or assume contingent liabilities, and subject us to other risks.
We have engaged in strategic collaborations in the past, such as our strategic collaborations with AbbVie, Innovent and GSK, and we may engage in
various acquisitions, collaborations, and strategic partnerships in the future, including licensing or acquiring complementary products, intellectual property
rights, technologies, or businesses. Any acquisition, collaboration, or strategic partnership may entail numerous risks, including:
•
•
•
•
•
•
•
•
increased operating expenses and cash requirements;
volatility with respect to the financial reporting related to such arrangements, such as our expected variability in the recognition of revenue
each quarter from the AbbVie and GSK Agreement based on the percentage-of-completion basis under the applicable accounting rules;
assumption of indebtedness or contingent liabilities;
potential goodwill impairment resulting from such acquisitions;
issuance of our equity securities which would result in dilution to our stockholders;
assimilation of operations, intellectual property, products, and product candidates of an acquired company by our partners, including
difficulties associated with integrating new personnel;
diversion of our management’s attention from our existing product programs and initiatives in pursuing such an acquisition, collaboration
or strategic partnership;
retention of key employees, the loss of key personnel, and uncertainties in our ability to maintain key business relationships;
89
•
•
•
risks and uncertainties associated with the other party to such a transaction, including the prospects of that party and their existing products
or product candidates and regulatory approvals; that may impact their ability to fulfill their obligations under such transaction;
risks that the other party to such a transaction may exercise its rights under the applicable agreement in a way that negatively impacts us;
and
our inability to generate revenue from acquired or partnered intellectual property, technology, and/or products sufficient to meet our
objectives or even to offset the associated transaction and maintenance costs.
In addition, if we undertake such a transaction, we may issue dilutive securities, assume or incur debt obligations, incur large one-time expenses,
and acquire intangible assets that could result in significant future amortization expense.
Our internal computer systems, or those used by our third-party research institution collaborators, CROs or other contractors or consultants, may fail
or suffer other breakdowns, cyberattacks, or information security breaches that could compromise the confidentiality, integrity, and availability of such
systems and data, result in material disruptions of our development programs and business operations, risk disclosure of confidential, financial, or
proprietary information, and affect our reputation.
Despite the implementation of security measures, our internal computer systems and those of our future CROs and other contractors and consultants
may be vulnerable to damage from computer viruses and unauthorized access. As the cyber-threat landscape evolves, especially as certain of our
employees have engaged in remote or hybrid work as a result of, or after, the COVID-19 pandemic, these attacks are growing in frequency, sophistication,
and intensity, and are becoming increasingly difficult to detect. Such attacks could include the use of key loggers or other harmful and virulent malware,
including ransomware or other denials of service, and can be deployed through malicious websites, the use of social engineering, and/or other means. If a
breakdown, cyberattack, or other information security breach were to occur and cause interruptions in our operations, it could result in a misappropriation
of confidential information, including our intellectual property or financial information, and a material disruption of our development programs and our
business operations. For example, the loss of clinical trial data from completed, ongoing, or future clinical trials could result in delays in our regulatory
approval efforts and significantly increase our costs to recover or reproduce the data. Likewise, we rely on third-party research institution collaborators and
CROs for research and development of our product candidates and other third parties for the manufacture of our product candidates and to conduct clinical
trials, and similar events relating to their computer systems could also have a material adverse effect on our business. To the extent that any disruption or
security breach were to result in a loss of, or damage to, our data or systems, or inappropriate disclosure of confidential, financial, or proprietary
information, including data related to our personnel, we could incur liability or risk disclosure of confidential, financial, or proprietary information, and the
further development and commercialization of our product candidates could be delayed. There can be no assurance that we and our business counterparties
will be successful in efforts to detect, prevent, or fully recover systems or data from all breakdowns, service interruptions, attacks, or breaches of systems
that could adversely affect our business and operations and/or result in the loss of critical or sensitive data, which could result in financial, legal, business,
or reputational harm to us.
Business disruptions, including as a result of global pandemics, could seriously harm our future revenue and financial condition and increase our
costs and expenses.
Our operations, and those of our collaborators, CROs, CDMOs, suppliers, and other contractors and consultants, could be subject to pandemic
events and other events beyond our control, such as the spread of disease, earthquakes, power shortages, telecommunications failures, water shortages,
floods, hurricanes, typhoons, fires, extreme weather conditions, medical epidemics, political unrest, including the Russia-Ukraine conflict and other natural
or man-made disasters or business interruptions, for which we are either totally or partly uninsured. In addition, we rely on our third-party research
institution collaborators for conducting research and development of our product candidates, and they may be affected by government shutdowns or
withdrawn funding. The occurrence of any of these business disruptions could seriously harm our operations and financial condition and increase our costs
and expenses. We rely on third-party manufacturers to produce and process our product candidates. Our ability to obtain clinical supplies of our product
candidates could be disrupted if the operations of these suppliers are affected by a man-made or natural disaster, global pandemics, or other business
interruption.
90
The majority of our operations including our corporate headquarters are located in a facility in South San Francisco, California. Damage or extended
periods of interruption to our corporate, development, or research facilities due to fire, natural disaster, global pandemics, power loss, communications
failure, unauthorized entry, earthquakes or other events could cause us to cease or delay development of some or all of our product candidates. Although we
maintain property damage and business interruption insurance coverage on these facilities, our insurance might not cover all losses under such
circumstances and our business may be seriously harmed by such delays and interruption.
Our business is subject to economic, political, regulatory, and other risks associated with international operations.
Our business is subject to risks associated with conducting business internationally. Some of our CDMOs and clinical trial sites, for example are
located outside the United States. Accordingly, our future results could be harmed by a variety of factors, including:
•
•
•
•
•
•
•
•
•
•
•
•
•
•
•
economic weakness, including inflation, or political instability in particular in non-U.S. economies and markets;
differing and changing regulatory requirements in non-U.S. countries;
challenges enforcing our contractual and intellectual property rights, especially in those foreign countries that do not respect and protect
intellectual property rights to the same extent as the United States;
difficulties in compliance with non-U.S. laws and regulations;
changes in non-U.S. regulations and customs, tariffs, and trade barriers;
changes in non-U.S. currency exchange rates and currency controls;
changes in a specific country’s or region’s political or economic environment;
shipping of biologics/drugs;
trade protection measures, import or export licensing requirements, or other restrictive actions by U.S. or non-U.S. governments;
negative consequences from changes in tax laws; (including the provisions of the recently enacted federal tax legislation titled the Inflation
Reduction Act);
compliance with tax, employment, immigration, and labor laws for employees living or traveling abroad;
workforce uncertainty in countries where labor unrest is more common than in the United States;
difficulties associated with staffing and managing international operations, including differing labor relations;
potential liability under the FCPA, UK Bribery Act, or comparable foreign laws; and
business interruptions resulting from geo-political actions, including war and terrorism, or natural disasters including earthquakes,
typhoons, floods, droughts, extreme temperatures, and fires.
These and other risks associated with our planned international operations may materially adversely affect our ability to attain profitable operations.
Our ability to use our net operating loss carryforwards and certain other tax attributes may be limited.
As of December 31, 2022, we had federal and state net operating loss (NOL) carryforwards of approximately $40.3 million and $203.5 million,
respectively. Federal NOL carryforwards have an indefinite life and deductions cannot exceed 80% of taxable income. Pursuant to Internal Revenue Code
Sections 382 and 383, annual use of the Company’s net operating loss and research and development credit carryforwards may be limited in the event that a
cumulative change in ownership of more than 50% occurs within a three-year period. As a result of our initial public
91
offering in February 2019 and follow-on public offering in January 2020, and other transactions that have occurred since our incorporation, we may have
experienced such an ownership change. We may also experience ownership changes in the future as a result of subsequent shifts in our stock ownership,
some of which are outside our control. As a result, our ability to use our pre-change net operating loss carryforwards and other pre-change tax attributes to
offset post-change taxable income or taxes may be subject to limitation. In addition, the enacted legislation commonly referred to as the Tax Cuts and Jobs
Act of 2017 (the TCJA), as amended by the Coronavirus Aid, Relief, and Economic Security Act of 2020 (CARES Act), also provides that NOLs from tax
years that began after December 31, 2017 may offset no more than 80% of current taxable income annually for taxable years beginning after December 31,
2022. Our NOLs may also be subject to limitations under state law.
Changes in tax laws or in their implementation or interpretation may adversely affect our business and financial condition.
We are or may become subject to income and non-income taxes in the United States under federal, state, and local jurisdictions and in certain
foreign jurisdictions in which we operate. Tax laws, regulations and administrative practices in these jurisdictions may be subject to significant change,
with or without advance notice. For example, on January 1, 2022, a provision of the TCJA went into effect that eliminates the option to deduct domestic
research and development costs in the year incurred and instead requires taxpayers to amortize such costs over five years for domestic costs and 15 years
for foreign costs. The Company is currently evaluating the potential impact. Also, the United States recently enacted the Inflation Reduction Act, which
introduced a 15% minimum tax on book income and a 1% excise tax on stock buybacks. Changes in tax laws (including provisions of the Inflation
Reduction Act), regulations, or rulings, changes in interpretations of existing laws and regulations, or changes in accounting principles could negatively or
materially affect our financial position, cash flows and results of operations.
General Risk Factors
The market price of our common stock may continue to be volatile, which could result in substantial losses for investors.
Although our common stock is listed on the NASDAQ Global Select Market, the market for our shares has demonstrated varying levels of trading
activity. The trading price of our common stock has been and may continue to be highly volatile and could be subject to wide fluctuations in response to
various factors, some of which are beyond our control. We cannot predict the prices at which our common stock will trade. It is possible that in one or more
future periods our results of operations and progression of our product pipeline may not meet the expectations of public market analysts and investors, and,
as a result of these and other factors, the price of our common stock may fall. Some of the factors that may cause the market price of our common stock to
fluctuate or decline include:
•
•
•
•
•
•
•
•
•
•
•
the success of existing or new competitive products or technologies;
the timing and results of clinical trials for our current product candidates and any future product candidates that we may develop;
commencement or termination of collaborations for our product development and research programs;
failure to achieve development, regulatory, or commercialization milestones under our collaborations;
failure or discontinuation of any of our product development and research programs;
results of preclinical studies, clinical trials, or regulatory approvals of product candidates of our competitors, or announcements about new
research programs or product candidates of our competitors;
regulatory or legal developments in the United States and other countries;
developments or disputes concerning patent applications, issued patents, or other proprietary rights;
the recruitment or departure of key personnel;
the level of expenses related to any of our research programs, clinical development programs, or product candidates that we may develop;
the results of our efforts to develop additional product candidates or products;
92
•
•
•
•
•
•
•
•
•
•
actual or anticipated changes in estimates as to financial results, development timelines, or recommendations by securities analysts;
announcement or expectation of additional financing efforts;
sales of our common stock by us, our insiders, or other stockholders, such as if we use our at-the-market facility;
expiration of market standoff or lock-up agreements;
variations in our financial results or those of companies that are perceived to be similar to us;
changes in estimates or recommendations by securities analysts, if any, that cover our stock;
changes in the structure of healthcare payment systems;
market conditions in the pharmaceutical and biotechnology sectors;
general economic, political, industry, and market conditions, including a rising rate of inflation or a period of economic recession; and
the other factors described in this “Risk Factors” section.
In recent years, the stock market in general, and the market for pharmaceutical and biotechnology companies in particular, has experienced
significant price and volume fluctuations that have often been unrelated or disproportionate to changes in the operating performance of the companies
whose stock is experiencing those price and volume fluctuations. Broad market and industry factors, such as inflationary concerns, may seriously affect the
market price of our common stock, regardless of our actual operating performance. Following periods of such volatility in the market price of a company’s
securities, securities class action litigation has often been brought against that company. Because of the potential volatility of our stock price, we may
become the target of securities litigation in the future. Securities litigation could result in substantial costs and divert management’s attention and resources
from our business.
If securities analysts do not publish research or reports about our business or if they publish negative evaluations of our stock, the price of our stock
could decline.
The trading market for our common stock relies in part on the research and reports that industry or financial analysts publish about us or our
business. If one or more of the analysts covering our business cease to cover us or downgrade their evaluations of our stock or if we fail to meet their
operating results estimates for us, the price of our stock could decline. If one or more of these analysts cease to cover our stock, we could lose visibility in
the market for our stock, which in turn could cause our stock price to decline.
Sales of substantial amounts of our common stock in the public markets, or the perception that such sales might occur, could cause the market price of
our common stock to decline significantly, even if our business is doing well.
Sales of a substantial number of shares of our common stock in the public market could occur at any time. If our stockholders sell, or the market
perceives that our stockholders intend to sell, substantial amount of our common stock in the public market, the market price of our common stock could
decline significantly.
Certain holders of shares of our common stock have rights, subject to conditions, to require us to file registration statements covering their shares or
to include their shares in registration statements that we may file for ourselves or other stockholders. Registration of these shares under the Securities Act
would result in the shares becoming freely tradeable in the public market, subject to the restrictions of Rule 144 in the case of our affiliates. Any sales of
securities by these stockholders could have a material adverse effect on the market price for our common stock.
Raising additional capital may cause dilution to our existing stockholders, restrict our operations, or require us to relinquish rights to our technologies
or product candidates.
We may seek additional capital through a combination of public and private equity offerings, debt financings, strategic partnerships and alliances,
and licensing arrangements. We, and indirectly, our stockholders, will bear the
93
cost of issuing and servicing such securities. Because our decision to issue debt or equity securities in any future offering will depend on market conditions
and other factors beyond our control, we cannot predict or estimate the amount, timing, or nature of any future offerings. To the extent that we raise
additional capital through the sale of equity or debt securities, your ownership interest will be diluted, and the terms may include liquidation or other
preferences that adversely affect your rights as a stockholder. The incurrence of indebtedness would result in increased fixed payment obligations and could
involve restrictive covenants, such as limitations on our ability to incur additional debt, limitations on our ability to acquire, sell, or license intellectual
property rights and other operating restrictions that could adversely impact our ability to conduct our business. We plan to file an omnibus shelf registration
statement on Form S-3 with the SEC, which, upon becoming effective, will permit us to issue up to $400 million in common stock, other equity securities
and/or debt securities. Additionally, any future collaborations we enter into with third parties may provide capital in the near term but limit our potential
cash flow and revenue in the future. If we raise additional funds through strategic partnerships and alliances and licensing arrangements with third parties,
we may have to relinquish valuable rights to our technologies or product candidates, or grant licenses on terms unfavorable to us.
Our principal stockholders and management own a significant percentage of our stock and will be able to exercise significant influence over matters
subject to stockholder approval.
Our directors, executive officers, holders of more than 5% of our outstanding stock and their respective affiliates beneficially own 50.2 percentage
of our outstanding common stock as of February 21, 2023. As a result, these stockholders, if they act together, may significantly influence all matters
requiring stockholder approval, including the election of directors and approval of significant corporate transactions. This concentration of ownership may
have the effect of delaying or preventing a change in control of our company that our other stockholders may believe is in their best interests. This in turn
could have a material adverse effect on our stock price and may prevent attempts by our stockholders to replace or remove the board of directors or
management.
We have incurred and will continue to incur significant additional costs as a result of operating as a public company, and our management will be
required to devote substantial time to new compliance initiatives and corporate governance practices.
As a public company, we have incurred and will continue to incur significant legal, accounting, and other expenses that we did not incur as a private
company. The Sarbanes-Oxley Act, the Dodd-Frank Wall Street Reform, and Consumer Protection Act, the listing requirements of NASDAQ, and other
applicable securities rules and regulations impose various requirements on public companies, including establishment and maintenance of effective
disclosure and financial controls and corporate governance practices. We have hired, and expect that we will need to continue to hire, additional
accounting, finance, and other personnel in connection with our becoming, and our efforts to comply with the requirements of being, a public company, and
our management and other personnel have devoted and will continue to devote a substantial amount of time towards maintaining compliance with these
requirements. These requirements have increased and will continue to increase our legal and financial compliance costs and will make some activities more
time-consuming and costly. For example, we expect that the rules and regulations applicable to us as a public company may make it more difficult and
more expensive for us to maintain director and officer liability insurance, which could make it more difficult for us to attract and retain qualified members
of our board of directors. We are currently evaluating these rules and regulations and cannot predict or estimate the amount of additional costs we may
incur or the timing of such costs. These rules and regulations are often subject to varying interpretations, in many cases due to their lack of specificity, and,
as a result, their application in practice may evolve over time as new guidance is provided by regulatory and governing bodies. This could result in
continuing uncertainty regarding compliance matters and higher costs necessitated by ongoing revisions to disclosure and governance practices.
If we are unable to maintain effective internal controls, our business, financial position, and results of operations could be adversely affected.
As a public company, we are subject to reporting and other obligations under the Exchange Act, including the requirements of Sarbanes-Oxley Act
Section 404(a), which require annual management assessments of the effectiveness of our internal control over financial reporting. Section 404(b) of the
Sarbanes-Oxley Act also requires our independent auditors to attest to, and report on, this management assessment.
94
The rules governing the standards that must be met for management to assess our internal control over financial reporting are complex and require
significant documentation, testing and possible remediation to meet the detailed standards under the rules. During the course of its testing, our management
may identify material weaknesses or deficiencies which may not be remedied in time to meet the deadline imposed by the Sarbanes-Oxley Act of 2002.
These reporting and other obligations place significant demands on our management and administrative and operational resources, including accounting
resources. If we are not able to comply with the requirements of Section 404 or if we or our independent registered public accounting firm are unable to
attest to the effectiveness of our internal control over financial reporting, investors may lose confidence in the accuracy and completeness of our financial
reports, the market price of our stock could decline and we could be subject to sanctions or investigations by Nasdaq, the SEC, or other regulatory
authorities, which would require additional financial and management resources.
Our operations are subject to the effects of a rising rate of inflation.
The United States has recently experienced historically high levels of inflation. According to the U.S. Bureau of Labor Statistics, the annual
consumer price index increase for the United States was approximately 6.5% for the 12 months ended December 31, 2022. If the inflation rate continues to
increase, it will affect our expenses, such as employee compensation and research and development charges. Research and development expenses account
for a significant portion of our operating expenses. Such increased charges may not be readily recoverable during the period of time that we are bringing
the product candidates to market. Additionally, the United States is experiencing an acute workforce shortage, which in turn, has created a very competitive
wage environment that may increase the Company’s operating costs. To the extent inflation results in rising interest rates and has other adverse effects on
the market, it may adversely affect our consolidated financial condition and results of operations.
We do not expect to pay any dividends for the foreseeable future. Investors may never obtain a return on their investment.
You should not rely on an investment in our common stock to provide dividend income. We do not anticipate that we will pay any dividends to
holders of our common stock in the foreseeable future. Instead, we plan to retain any earnings to maintain and expand our existing operations. In addition,
any future credit facility may contain terms prohibiting or limiting the amount of dividends that may be declared or paid on our common stock.
Accordingly, investors must rely on sales of their common stock after price appreciation, which may never occur, as the only way to realize any return on
their investment. As a result, investors seeking cash dividends should not purchase our common stock.
Delaware law and provisions in our amended and restated certificate of incorporation and bylaws might discourage, delay, or prevent a change in
control of our company or changes in our management and, therefore, depress the trading price of our common stock.
Provisions in our amended and restated certificate of incorporation and bylaws may discourage, delay, or prevent a merger, acquisition, or other
change in control that stockholders may consider favorable, including transactions in which you might otherwise receive a premium for your shares of our
common stock. These provisions may also prevent or frustrate attempts by our stockholders to replace or remove our management. Therefore, these
provisions could adversely affect the price of our common stock. Among other things, our charter documents:
•
•
•
•
•
establish that our board of directors is divided into three classes, Class I, Class II, and Class III, with each class serving staggered three-year
terms;
provide that vacancies on our board of directors may be filled only by a majority of directors then in office, even though less than a
quorum;
provide that our directors may only be removed for cause;
eliminate cumulative voting in the election of directors;
authorize our board of directors to issue shares of preferred stock and determine the price and other terms of those shares, including
preferences and voting rights, without stockholder approval;
95
•
•
•
•
•
•
provide our board of directors with the exclusive right to elect a director to fill a vacancy or newly created directorship;
permit stockholders to only take actions at a duly called annual or special meeting and not by written consent;
prohibit stockholders from calling a special meeting of stockholders;
require that stockholders give advance notice to nominate directors or submit proposals for consideration at stockholder meetings;
authorize our board of directors, by a majority vote, to amend the bylaws; and
require the affirmative vote of at least 66 2/3% or more of the outstanding shares of common stock to amend many of the provisions
described above.
In addition, Section 203 of the General Corporation Law of the State of Delaware (DGCL), prohibits a publicly-held Delaware corporation from
engaging in a business combination with an interested stockholder, generally a person which together with its affiliates owns, or within the last three years
has owned, 15% of our voting stock, for a period of three years after the date of the transaction in which the person became an interested stockholder,
unless the business combination is approved in a prescribed manner.
Any provision of our amended and restated certificate of incorporation, amended and restated bylaws, or Delaware law that has the effect of
delaying or preventing a change in control could limit the opportunity for our stockholders to receive a premium for their shares of our capital stock and
could also affect the price that some investors are willing to pay for our common stock.
Our amended and restated bylaws provide that the Court of Chancery of the State of Delaware is the exclusive forum for substantially all disputes
between us and our stockholders, which could limit our stockholders’ ability to obtain a favorable judicial forum for disputes with us or our directors,
officers, or employees.
Our amended and restated bylaws provide that the Court of Chancery of the State of Delaware (or, if the Court of Chancery does not have
jurisdiction, another State court in Delaware or the federal district court for the District of Delaware) is the exclusive forum for the following (except for
any claim as to which such court determines that there is an indispensable party not subject to the jurisdiction of such court (and the indispensable party
does not consent to the personal jurisdiction of such court within 10 days following such determination), which is vested in the exclusive jurisdiction of a
court or forum other than such court, or for which such court does not have subject matter jurisdiction):
•
•
•
•
any derivative action or proceeding brought on our behalf;
any action asserting a claim of breach of fiduciary duty;
any action asserting a claim against us arising under the DGCL, our amended and restated certificate of incorporation or our amended and
restated bylaws; and
any action asserting a claim against us that is governed by the internal-affairs doctrine.
This provision would not apply to suits brought to enforce a duty or liability created by the Exchange Act or any other claim for which the U.S.
federal courts have exclusive jurisdiction.
Our amended and restated bylaws further provide that the federal district courts of the United States will be the exclusive forum for resolving any
complaint asserting a cause of action arising under the Securities Act. These exclusive-forum provisions may limit a stockholder’s ability to bring a claim
in a judicial forum that it finds favorable for disputes with us or our directors, officers or other employees, which may discourage lawsuits against us and
our directors, officers and other employees. Any person or entity purchasing or otherwise acquiring any interest in any of our securities shall be deemed to
have notice of and consented to these provisions. There is uncertainty as to whether a court would enforce such provisions, and the enforceability of similar
choice of forum provisions in other companies’ charter documents has been challenged in legal proceedings. It is possible that a court could find these
types of provisions to be inapplicable or unenforceable, and if a court were to find either exclusive-forum provision in our amended and restated bylaws to
be inapplicable or unenforceable in an action, we
96
may incur additional costs associated with resolving the dispute in other jurisdictions, which could seriously harm our business.
Item 1B. Unresolved Staff Comments.
None.
Item 2. Properties.
Our corporate headquarters are currently located in South San Francisco, California, where we lease approximately 105,000 square feet of office and
laboratory space. The term of the lease agreement expires in May 2029, with an option to extend the term of the lease for an additional 10 years. The lease
agreement also provides us a right of first offer to expand into available office space in the building. We subleased approximately 7,132 square feet of our
corporate headquarters in November 2021 with a lease term that expired in December 2022. Additionally, we subleased approximately 13,150 square feet
of our corporate headquarters in May 2022 with a lease term that will expire in November 2023. We also subleased approximately 9,275 square feet of our
corporate headquarters in February 2023 with a lease term that will expire in January 2025. We lease approximately 18,700 square feet of additional office
and laboratory space in Newark, California. We believe that these facilities will be adequate for our near-term needs. If required, we believe that suitable
additional or alternative space would be available in the future on commercially reasonable terms.
Item 3. Legal Proceedings.
From time to time, we may become involved in litigation or other legal proceedings. We are not currently a party to any litigation or legal
proceedings that, in the opinion of our management, are likely to have a material adverse effect on our business. Regardless of outcome, litigation, or other
legal proceedings can have an adverse impact on us because of legal fees and settlement costs, diversion of management resources, and other factors.
Item 4. Mine Safety Disclosures.
Not applicable.

Item 5. Market for Registrant’s Common Equity, Related Stockholder Matters and Issuer Purchases of Equity Securities.
Market Information for Common Stock
Our common stock is publicly traded on the Nasdaq Global Select Market under the symbol "ALEC."
PART II
Holders of Record
As of February 21, 2023, there were approximately 7 stockholders of record of our common stock. The actual number of stockholders is greater than
this number of record holders and includes stockholders who are beneficial owners but whose shares are held in street name by brokers and other nominees.
Dividend Policy
We have not declared or paid any cash dividends on our capital stock since our inception. We intend to retain future earnings, if any, to finance the
operation and expansion of our business and do not anticipate paying any cash dividends in the foreseeable future. Payment of future cash dividends, if any,
will be at the discretion of our board of directors after taking into account various factors, including our financial condition, operating results, current and
anticipated cash needs, the requirements and contractual restrictions of then-existing debt instruments, and other factors that our board of directors deems
relevant.
Stock Performance Graph
This graph is not “soliciting material” or deemed “filed” with the SEC for purposes of Section 18 of the Exchange Act, or otherwise subject to
liabilities under that Section, and shall not be deemed incorporated by reference into any filing of Alector, Inc. under the Securities Act of 1933, as
amended (the "Securities Act"), whether made before or after the date hereof and irrespective of any general incorporation language in any such filing.
The following graph compares the cumulative total return to stockholder return on our common stock relative to the cumulative total returns of the
NASDAQ Composite Index and the NASDAQ Biotechnology Index. An investment of $100 is assumed to have been made in our common stock and each
index on February 7, 2019 (the first day of trading of our common stock) and its relative performance is tracked through December 31, 2022. Pursuant to
applicable Securities and Exchange Commission rules, all values assume reinvestment of the full amount of all dividends, however no dividends have been
declared on our common stock to date. The stockholder returns shown on the graph below are based on historical results and are not necessarily indicative
of future performance, and we do not make or endorse any predictions as to future stockholder returns.

Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations.
You should read the following discussion and analysis of our financial condition and results of operations together with our consolidated financial
statements and related notes included elsewhere in this Annual Report on Form 10-K. This discussion contains forward-looking statements that involve
risks and uncertainties, including those described in the section titled “Special Note Regarding Forward Looking Statements.” Our actual results and the
timing of selected events could differ materially from those discussed below. Factors that could cause or contribute to such differences include, but are not
limited to, those identified below and those set forth under the section titled “Risk Factors” included elsewhere in this report.
Overview
We are a clinical stage biopharmaceutical company pioneering immuno-neurology, a novel therapeutic approach for the treatment of
neurodegeneration. Immuno-neurology targets immune dysfunction as a root cause of multiple pathologies that are drivers of degenerative brain disorders.
We are developing therapies designed to counteract these pathologies simultaneously by restoring healthy immune function to the brain. Supporting our
scientific approach, our research and drug discovery platform enables us to advance a broad portfolio of product candidates, validated by human genetics,
which we believe will improve the probability of technical success over shorter development timelines. As a result, we have identified over 100 immune
system targets. Three product candidates, latozinemab (also referred to as AL001), AL002, and AL101 are in clinical development, and we continue to
develop our research pipeline, including AL009 and AL008. We recently completed a prioritization review, focusing our development resources on our
progranulin and TREM2 programs and extending our cash runway through 2025. We are advancing our clinical product candidates and research pipeline
with our existing resources and in collaboration with our partners, GSK and AbbVie.
Our operations have been financed primarily through our collaborations with AbbVie and GSK and the issuance and sale of convertible preferred
stock and of common stock upon the completion of our initial public offering (IPO) and follow-on offering. We completed our IPO in February 2019, and
received $168.2 million net proceeds, after deducting underwriting discounts and commissions and offering expenses. We completed a
99
follow-on offering in January 2020 and received $224.5 million net proceeds, after deducting underwriting discounts and commissions and offering
expenses.
To date, we have not had any products approved for sale and have not generated any revenue from product sales. Further, we do not expect to
generate revenue from product sales until such time, if ever, that we are able to successfully complete the development and obtain marketing approval for
one of our product candidates. We will continue to require additional capital to develop our product candidates and fund operations for the foreseeable
future. We have incurred net losses in each year since inception and we expect to continue to incur net losses for the foreseeable future. Our ability to
generate product revenue will depend on the successful development and eventual commercialization of one or more of our product candidates. Our net
losses were $133.3 million, $36.3 million, and $190.2 million for the years ended December 31, 2022, 2021, and 2020, respectively. As of December 31,
2022, we had an accumulated deficit of $579.7 million. Substantially all of our net losses have resulted from costs incurred in connection with our research
and development programs and from general and administrative costs associated with our operations. We expect our expenses will increase substantially in
connection with our ongoing activities, as we:
•
•
•
•
•
•
advance product candidates through preclinical studies and clinical trials;
pursue regulatory approval of product candidates;
hire additional personnel;
acquire, discover, validate, and develop additional product candidates;
require the manufacture of supplies for our preclinical studies and clinical trials; and
obtain, maintain, expand, and protect our intellectual property portfolio.
Components of Results of Operations
Revenue
We have not generated any revenue from product sales and do not expect to do so in the near future. Our revenue to date has been primarily related
to the AbbVie Agreement and GSK Agreement for the license and co-development of product candidates with those parties. We recognize revenue from the
upfront payments from AbbVie over time as services are provided. We recognize revenue from the upfront payments from GSK at a point in time for a
development license and over time for research and development services. Revenues for research and development services are recognized as the program
costs are incurred by measuring actual costs incurred to date compared to the overall total expected costs to satisfy the performance obligation.
Under the terms of our AbbVie Agreement, in addition to receiving the upfront payments from AbbVie, we may also be entitled to development and
regulatory milestone payments, opt-in payments for continued development after proof-of-concept for AL002, and other future payments from profit
sharing or royalties after commercialization of product candidates from such program.
Under the terms of our GSK Agreement, we received $700 million in upfront payments, of which $500 million was received in August 2021 and
$200 million was received in January 2022. In addition, we will be eligible to receive up to an additional $1.5 billion in clinical development, regulatory,
and commercial launch-related milestone payments for latozinemab and AL101. Alector and GSK are jointly developing latozinemab and AL101.
In the United States, Alector and GSK will equally share profits and losses from commercialization of latozinemab and AL101. We may opt out of
the sharing of development costs and of profit and losses from commercialization in the United States on a product-by-product basis. In such case, we will
no longer conduct development or commercialization of that product and we will receive royalties on net sales of the product in the United States instead of
a share of profits. Outside of the United States, GSK will be responsible for commercialization of latozinemab and AL101 for all indications, and we will
be eligible for double-digit tiered royalties.
We expect that our revenue for the next several years will be derived primarily from the AbbVie and GSK Agreements. The balance of deferred
revenue was $491.6 million as of December 31, 2022, related to the AbbVie and GSK Agreements. The deferred revenue is expected to be recognized over
the research and development period of the programs through proof-of-concept for AL002 and the completion of the initial Phase 2 clinical trials for
specified indications for latozinemab and AL101.
100
Research and Development Expenses
Research and development expenses account for a significant portion of our operating expenses. We record research and development expenses as
incurred. Research and development expenses consist primarily of costs incurred for the discovery and development of our product candidates, which
include:
•
•
•
•
•
•
•
expenses incurred under agreements with third-party contract organizations, preclinical testing organizations, and consultants;
costs related to production of clinical materials, including fees paid to contract manufacturers;
laboratory and vendor expenses related to the execution of preclinical studies and clinical trials;
personnel-related expenses, including salaries, benefits, and stock-based compensation for personnel engaged in research and development
functions;
costs related to the preparation of regulatory submissions;
third-party license fees; and
facilities and other expenses, which include expenses for rent and maintenance of facilities, depreciation and amortization expense, and other
supplies.
We expense all research and development costs in the periods in which they are incurred. Costs for certain development activities are recognized
based on an evaluation of the progress to completion of specific tasks using information and data provided to us by our vendors, collaborators, and third-
party service providers. Nonrefundable advance payments for goods or services to be received in future periods for use in research and development
activities are deferred and capitalized. The capitalized amounts are then expensed as the related goods are delivered and as services are performed.
Specific program expenses include expenses associated with the development of our most advanced product candidates: latozinemab, which is being
studied in a pivotal Phase 3 clinical trial, INFRONT-3, which has an ongoing Phase 2 clinical trial; AL002, which is being studied in a Phase 2 clinical
trial; and AL101, for which we have completed a Phase 1 clinical trial. We also have expenses related to the discovery and development of future product
candidates and separately tracked expenses related to programs that we expect to move out of preclinical studies and into Phase 1 clinical trials. These
expenses primarily relate to salaries and benefits, stock-based compensation, facility expenses, including depreciation, and lab consumables.
Where we share costs with our collaboration partners, such as in our GSK Agreement, research and development expenses may include cost sharing
reimbursements from, or payments to, our partner.
At this time, we cannot reasonably estimate or know the nature, timing, and estimated costs of the efforts that will be necessary to complete the
development of, and obtain regulatory approval for, any of our product candidates. We expect our research and development expenses to increase
substantially for the foreseeable future as we continue to invest in research and development activities related to developing our product candidates, as our
product candidates advance into later stages of development, as we begin to conduct larger clinical trials, as we seek regulatory approvals for any product
candidates that successfully complete clinical trials, and incur expenses associated with hiring additional personnel to support our research and
development efforts. The process of conducting the necessary clinical research to obtain regulatory approval is costly and time-consuming, and the
successful development of our product candidates is highly uncertain.
General and Administrative Expenses
General and administrative expenses consist primarily of personnel-related costs, including stock-based compensation, for our personnel in
executive, legal, finance and accounting, information technology, human resources, and other administrative functions. General and administrative
expenses also include legal fees relating to intellectual property and corporate matters, professional fees paid for accounting, auditing, consulting, and tax
services, insurance costs, and facility costs not otherwise included in research and development expenses.

Revenue
Collaboration revenue was $133.6 million for the year ended December 31, 2022, compared to $207.1 million for the year ended December 31,
2021. The decrease of $73.4 million was mostly due to the $173.4 million collaboration revenue recognized from the latozinemab FTD-GRN license
provided as part of the GSK Agreement in 2021. This was offset by a $55.8 million net increase to collaboration revenue under the AbbVie Agreement due
to changes in estimated costs to satisfy the performance obligations resulting from the termination of the AL003 program, partially offset by increases in
total expected costs for the AL002 program. The decrease was also offset by $44.2 million higher revenue for GSK programs recognized over the initial
Phase 2 clinical trials.
Research and Development Expenses
Research and development expenses were $210.4 million for the year ended December 31, 2022, compared to $189.4 million for the year ended
December 31, 2021. The increase of $21.0 million was driven by a $17.5 million increase in personnel-related expenses, including stock-based
compensation, due to an increase in headcount and issuance of equity grants to employees. In addition, we had an $8.9 million increase for AL002 as it
further progresses in clinical trials and a $5.9 million increase in facilities and other unallocated research and development expenses from additional rent
expense, headcount, and other overhead costs. This was offset by a $9.6 million decrease in latozinemab mainly due to the cost sharing agreement with
GSK.

General and Administrative Expenses
General and administrative expenses were $61.0 million for the year ended December 31, 2022, compared to $55.0 million for the year ended
December 31, 2021. The increase of $6.0 million was driven by a $4.9 million increase in personnel-related expenses, including stock-based compensation,
due to an increase in headcount and issuance of equity grants to employees. We also had an increase of $1.1 million mainly related to information
technology to support our growth.
Other Income, Net
Other income, net was $7.8 million for the year ended December 31, 2022, compared to $1.0 million for the year ended December 31, 2021. The
increase of $6.7 million was due to higher investment yields on our marketable securities compared to the prior year.
Income Tax Expense
Income tax expense was $3.3 million for the year ended December 31, 2022, compared to zero for the year ended December 31, 2021. Beginning
January 1, 2022, the TCJA requires taxpayers to capitalize and amortize research and development expenses rather than take an immediate deduction
pursuant to Section 174 of the Internal Revenue Code. The increase of $3.3 million was primarily due to the impact of this new law on the cash received
from the GSK Agreement.
Liquidity and Capital Resources
Since our inception through December 31, 2022, our operations have been financed primarily by our collaborations with AbbVie and GSK and the
issuance and sale of convertible preferred stock and of common stock upon the completion of our IPO and follow-on offering.
As of December 31, 2022, we had $712.9 million of cash, cash equivalents, and marketable securities. As of December 31, 2022, we had an
accumulated deficit of $579.7 million.
Future Funding Requirements
Our primary uses of cash are to fund our operations, which consist primarily of research and development expenditures related to our programs, and
to a lesser extent, general and administrative expenditures. We expect our expenses to continue to increase in connection with our ongoing activities, in
particular as we continue to advance our product candidates and our discovery programs. In addition, we expect to incur additional costs associated with
operating as a public company.
Based on our current operating plan, we believe that our existing cash, cash equivalents, and marketable securities will enable us to fund our
operations and capital expenditure requirements through 2025. We have based
103
this estimate on assumptions that may prove to be wrong, and we could utilize our available capital resources sooner than we currently expect. We may also
choose to seek additional financing opportunistically. We may seek to raise capital through public equity or debt financings, license agreements,
collaborative agreements or other arrangements with other companies, asset sales, or through other sources of financing. We expect to need to obtain
substantial additional funding in the future for our research and development activities and continuing operations. If we were unable to raise capital when
needed or on favorable terms, we would be forced to delay, reduce, or eliminate our research and development programs or future commercialization
efforts.
Our future capital requirements will depend on many factors, including:
•
•
•
•
•
•
•
•
•
•
•
•
•
the timing and progress of preclinical and clinical development activities; including, without limitation, our collaboration efforts with AbbVie
and GSK;
the number and scope of preclinical and clinical programs we decide to pursue;
successful enrollment in and completion of clinical trials;
our ability to establish agreements with third-party manufacturers for clinical supply for our clinical trials and, if our product candidates are
approved, commercial manufacturing;
our ability to maintain our current research and development programs and establish new research and development programs;
addition and retention of key research and development personnel;
our efforts to enhance operational, financial, and information management systems, and hire additional personnel, including personnel to
support development of our product candidates;
negotiating favorable terms in any collaboration, licensing, or other arrangements into which we may enter and performing our obligations in
such collaborations;
the timing and amount of milestone and other payments we may receive under our collaboration arrangements;
the costs and timing of regulatory approvals;
our eventual commercialization plans for our product candidates;
the effects of inflationary pressures; and
the costs involved in prosecuting, defending, and enforcing patent claims and other intellectual property claims.
A change in the outcome of any of these or other variables with respect to the development of any of our product candidates could significantly
change the costs and timing associated with the development of that product candidate. Furthermore, our operating plans may change in the future, and we
may need additional funds to meet operational needs and capital requirements associated with such operating plans.

For the year ended December 31, 2022, cash used in operating activities was $20.3 million. This was due to the net loss of $133.3 million offset by
an increase in deferred revenue of $66.4 million from the $200 million
104
upfront payment received less revenue recognized. In addition, we had non-cash charges of $46.1 million for stock-based compensation.
For the year ended December 31, 2021, cash provided by operating activities was $298.6 million. This was due to the net loss of $36.3 million offset
by an increase in deferred revenue of $292.9 million from the $500 million upfront payment received in the third quarter of 2021 from GSK. In addition,
we had non-cash charges of $40.8 million for stock-based compensation and $6.3 million for depreciation and amortization expense.
For the year ended December 31, 2020, cash used in operating activities was $166.7 million. This was mainly due to the net loss of $190.2 million
and the decrease in deferred revenue of $21.1 million as revenue was recognized related to the AbbVie Agreement. This was partially offset by a non-cash
charges of $30.5 million for stock-based compensation and $5.9 million for depreciation and amortization expense. We also had an increase of $12.2
million in accrued liabilities and accrued clinical supply costs, which offset the cash used in operating activities.
Investing Activities
For the year ended December 31, 2022, cash used in investing activities of $159.0 million was primarily related to the maturities of marketable
securities of $402.0 million offset by purchases of marketable securities of $556.9 million.
For the year ended December 31, 2021, cash used in investing activities of $49.7 million was primarily related to the maturities of marketable
securities of $286.3 million offset by purchases of marketable securities of $343.4 million and sales of marketable securities of $10.7 million.
For the year ended December 31, 2020, cash used in investing activities of $105.1 million was primarily related to the purchase of marketable
securities of $506.8 million offset by the proceeds from maturities of marketable securities of $406.8 million. In addition, we used cash for the purchase of
$5.0 million of property and equipment.
Financing Activities
For the year ended December 31, 2022, cash provided by financing activities of $4.5 million was primarily from the exercise of options to purchase
common stock.
For the year ended December 31, 2021, cash provided by financing activities of $30.3 million was primarily from the exercise of options to purchase
common stock.
For the year ended December 31, 2020, cash provided by financing activities of $232.1 million was primarily from net proceeds of the issuance of
9,602,500 shares of our common stock upon the completion of a follow-on public offering. In addition, we received $6.3 million cash from the exercise of
options to purchase common stock
Critical Accounting Policies and Estimates
Management’s discussion and analysis of our financial condition and results of operations is based on our consolidated financial statements, which
have been prepared in accordance with generally accepted accounting principles in the United States (GAAP). The preparation of these financial statements
requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities
at the date of the financial statements, as well as the reported revenue generated and expenses incurred during the reporting periods. Our estimates are
based on our historical experience and on various other factors that we believe are reasonable under the circumstances, the results of which form the basis
for making judgments about the carrying value of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these
estimates under different assumptions or conditions and any such differences may be material. We believe that the accounting policies discussed below are
critical to understanding our historical and future performance, as these policies relate to the more significant areas involving management’s judgments and
estimates.
Revenue Recognition
We recognize revenue when control of promised goods or services is transferred to customers in an amount that reflects the consideration that is
expected to be received for those goods or services. In determining the appropriate amount of revenue to be recognized as we fulfill our obligations under
arrangements, we perform the
105
following steps: (i) identify the contract(s) with a customer, (ii) identify the performance obligations in the contract, (iii) determine the transaction price,
(iv) allocate the transaction price to the performance obligations in the contract, and (v) recognize revenue when (or as) the entity satisfies the performance
obligation. If it is determined that multiple performance obligations exist, the transaction price is allocated at the inception of the agreement to all identified
performance obligations based on the relative standalone selling price (SSP). The relative SSP for each deliverable is estimated using external sourced
evidence if it is available. If external sourced evidence is not available, we use our best estimate of the SSP for the deliverable.
We recognize collaboration revenue at a point in time if control of the promised good or service has been transferred to the customer. We recognize
collaboration revenue over time by measuring the progress toward complete satisfaction of the performance obligation using an input measure. In order to
recognize revenue over the research and development period, we measure actual costs incurred to date compared to the overall total expected costs to
satisfy the performance obligation. Revenues are recognized as the program costs are incurred. We re-evaluate the estimate of expected costs to satisfy the
performance obligation each reporting period and make adjustments for any significant changes. Clinical trials are expensive and can take many years to
complete, and the outcome is inherently uncertain. Changes in our forecasted costs are likely to occur over time based upon changes in clinical trial
procedures set forth in protocols, changes in estimates of manufacturing costs, or feedback from regulators on the design or operation of our clinical trials.
We have had changes to the overall expected costs to satisfy the performance obligations from period to period. For the year ended December 31, 2022, we
recorded a net increase to collaboration revenue under the AbbVie Agreement due to changes in estimated costs to satisfy the performance obligations
resulting from the termination of the AL003 program, partially offset by increases in total expected costs for the AL002 program.
Accrued Research and Development Expenses
We record accrued expenses for estimated preclinical study and clinical trial expenses. Estimates are based on the services performed pursuant to
contracts with research institutions, CROs in connection with clinical studies, investigative sites in connection with clinical studies, vendors in connection
with preclinical development activities, and contract manufacturing organizations in connection with the production of materials for clinical trials. Further,
we accrue expenses related to clinical trials based on the level of patient enrollment and activity according to the related agreement. We monitor patient
enrollment levels and related activity to the extent reasonably possible and make judgments and estimates in determining the accrued balance in each
reporting period. If we underestimate or overestimate the level of services performed or the costs of these services, our actual expenses could differ from
our estimates. To date, we have not experienced significant changes in our estimates of preclinical studies and clinical trial accruals.
Stock-based Compensation
Stock-based compensation is measured at the date of grant, based on the estimated fair value of the award and recognized as expense over the
employee’s requisite service period (usually the vesting period). We estimate the grant date fair value for options to purchase common stock, and the
resulting stock-based compensation, using the Black-Scholes option-pricing model.
The Black-Scholes option-pricing model requires the use of highly subjective assumptions which determine the fair value of stock-based awards.
These assumptions include:
Expected Term—The expected term represents the period that stock-based awards are expected to be outstanding. The expected term was derived by
using the simplified method which uses the midpoint between the average vesting term and the contractual expiration period of the stock-based
award.
Expected Volatility—We have limited information on the volatility of our stock as shares of our common stock were not actively traded on any
public markets prior to February 7, 2019. The expected volatility was derived from the historical stock volatilities of comparable peer public
companies within our industry. These companies are considered to be comparable to our business over a period equivalent to the expected term of
the stock-based awards. In 2020, we began giving weight to our own historical volatility in the determination of expected volatility.
Risk-Free Interest Rate—The risk-free interest rate is based on the U.S. Treasury yield curve in effect at the measurement date with maturities
approximately equal to the expected term.
106
Expected Dividend—The expected dividend rate is zero because we have not historically paid and do not expect for the foreseeable future to pay a
dividend on our common stock.
Stock-based compensation associated with RSUs is based on the fair value of our common stock on the grant date, which equals the closing price of
our common stock on the grant date. We recognize expense over the vesting period of the awards. Expense for options and RSUs are recognized on a
straight-line basis.
We also granted RSUs with market conditions to certain executives. The fair value of the RSUs with market conditions are estimated using a Monte
Carlo simulation model. Assumptions and estimates utilized in the model include the stock price on grant date, risk-free interest rate, dividend yield,
expected stock volatility, and the estimated period to achieve the market condition. The expense is recognized based on continued employment of the
participants, regardless of achievement of the market condition. Expense related to the RSUs with market conditions is recognized using the accelerated
attribution method.
We account for forfeitures as they occur for all awards.
Item 7A. Quantitative and Qualitative Disclosures About Market Risk.
Interest Rate Risk
We are exposed to market risks in the ordinary course of our business. These risks primarily include interest rate sensitivities. The primary objective
of our investment activities is to preserve capital to fund our operations. We also seek to maximize income from our investments without assuming
significant risk. To achieve our objectives, we maintain a portfolio of investments in a variety of securities of high credit quality and generally short-term
duration, invested in compliance with our policy.
We had cash, cash equivalents, and marketable securities of $712.9 million as of December 31, 2022, which consisted primarily of bank deposits,
money market funds, and short-term government marketable securities. Such interest-earning instruments carry a degree of interest rate risk; however,
historical fluctuations in interest income have not been significant for us. Due to the generally short-term maturities of our cash equivalents and marketable
securities, and the low risk profile of our marketable securities, an immediate 100 basis point increase or decrease in interest rates would cause a change in
fair value of approximately $2.6 million as of December 31, 2022.
Foreign Currency Risk
Our expenses are generally denominated in U.S. dollars. However, we have entered into a limited number of contracts with vendors for research and
development services with payments denominated in foreign currencies, including the Euro. We are subject to foreign currency transaction gains or losses
on our contracts denominated in foreign currencies. To date, foreign currency transaction gains and losses have not been material to our financial
statements, and we have not had a formal hedging program with respect to foreign currency. A 10% increase or decrease in current exchange rates would
not have a material effect on our financial results.

Report of Independent Registered Public Accounting Firm
To the Stockholders and the Board of Directors of Alector, Inc.
Opinion on the Financial Statements
We have audited the accompanying consolidated balance sheets of Alector, Inc. (the Company) as of December 31, 2022 and 2021, the related consolidated
statements of operations and comprehensive loss, stockholders' equity and cash flows for each of the three years in the period ended December 31, 2022,
and the related notes (collectively referred to as the “consolidated financial statements”). In our opinion, the consolidated financial statements present
fairly, in all material respects, the financial position of the Company at December 31, 2022 and 2021, and the results of its operations and its cash flows for
each of the three years in the period ended December 31, 2022, in conformity with U.S. generally accepted accounting principles.
We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the Company's
internal control over financial reporting as of December 31, 2022, based on criteria established in Internal Control-Integrated Framework issued by the
Committee of Sponsoring Organizations of the Treadway Commission (2013 framework) and our report dated February 28, 2023 expressed an unqualified
opinion thereon.
Basis for Opinion
These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on the Company’s financial
statements based on our audits. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the
Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the
PCAOB.
We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable
assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. Our audits included performing
procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to
those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits
also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the
financial statements. We believe that our audits provide a reasonable basis for our opinion.
Critical Audit Matter
The critical audit matter communicated below is a matter arising from the current period audit of the financial statements that was communicated or
required to be communicated to the audit committee and that: (1) relates to accounts or disclosures that are material to the financial statements and (2)
involved our especially challenging, subjective or complex judgments. The communication of the critical audit matter does not alter in any way our
108
opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate
opinion on the critical audit matter or on the account or disclosure to which it relates.
Revenue Recognition
Description of the Matter
The Company recorded collaboration revenue of $133.6 million for the year ended December 31, 2022. As
described in Note 2, collaboration revenue is recognized by measuring the progress toward complete satisfaction of
the performance obligations using an input measure. In order to recognize collaboration revenue over the research
and development period, the Company measures actual costs incurred to date compared to the overall total
expected costs to satisfy the performance obligations. Revenues are recognized as the program costs are incurred.
Auditing collaboration revenue was challenging as it involves assessing highly judgmental estimates with respect to
the Company’s determination of the total expected costs to satisfy the performance obligations.
How We Addressed the Matter in
Our Audit
We obtained an understanding, evaluated the design and tested the operating effectiveness of internal controls that
address the identified risks related to the Company's process used to determine total expected costs to satisfy the
performance obligations, including management’s controls over updates to the budget for the relevant research and
development programs.
To test collaboration revenue, our audit procedures included, among others, obtaining an understanding of the
Company’s estimated costs to satisfy the performance obligations, as well as assessing management’s updates to
the budget for the relevant research and development programs. We also tested a sample of expenses recorded to
the development program, evaluated the historical accuracy of management’s budget estimates for the relevant
research and development programs, and inquired of Company personnel directly involved with supervising the
development programs.

The Company and Liquidity
Alector, Inc. (Alector or the Company) is a Delaware corporation headquartered in South San Francisco, California. Alector is a clinical stage
biopharmaceutical company pioneering immuno-neurology, a novel therapeutic approach for the treatment of neurodegeneration.
Follow-on Offering
On January 30, 2020, the Company completed a follow-on offering through issuing and selling 9,602,500 shares of common stock at a public
offering price of $25.00 per share, including 1,252,500 shares sold pursuant to the underwriters’ full exercise of their option to purchase additional
shares, resulting in aggregate net proceeds of $224.5 million, after deducting underwriting discounts and commissions and estimated offering costs.
2.
Summary of Significant Accounting Policies
Basis of Presentation
The consolidated financial statements have been prepared in conformity with generally accepted accounting principles in the United States (GAAP)
as defined by the Financial Accounting Standards Board (FASB). The consolidated financial statements include the accounts of Alector, Inc. and its
wholly owned subsidiaries. All intercompany balances and transactions have been eliminated in consolidation.
Use of Estimates
The preparation of consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect
the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements
and the reported amounts of revenue and expense during the reporting period. The Company evaluates its estimates, including those related to
revenue recognition, manufacturing accruals, clinical accruals, fair value of assets and liabilities, income taxes uncertainties, stock-based
compensation, and related assumptions on an ongoing basis using historical experience and other factors and adjusts those estimates and
assumptions when facts and circumstances dictate. Actual results could materially differ from those estimates.
Concentration of Credit Risk
Financial instruments that potentially subject the Company to significant concentrations of credit risk consist primarily of cash, cash equivalents,
and short-term marketable securities. Cash and cash equivalents are deposited in checking and sweep accounts at financial institutions. Such
deposits may, at times, exceed federally insured limits.
Cash, Cash Equivalents, and Restricted Cash
The Company considers all highly liquid investments with original maturities of three months or less at the date of purchase to be cash and cash
equivalents. Cash equivalents, which consist of amounts invested in money market funds, are stated at fair value.
Restricted cash as of December 31, 2022 relates to a letter of credit established for a lease entered into in June 2018.

The following table provides a reconciliation of cash, cash equivalents, and restricted cash reported within the consolidated balance sheets that sum

All marketable securities have been classified as “available-for-sale” and are carried at fair value, based upon quoted market prices. The Company
considers its available-for-sale portfolio as available for use in current operations. Accordingly, the Company may classify certain investments as
short-term marketable securities, even though the stated maturity date may be one year or more beyond the current balance sheet date. For available-
for-sale debt securities, unrealized gains, net of any related tax effects, are excluded from earnings and are included in other comprehensive income
and reported as a separate component of stockholders’ equity until realized. The Company assesses available-for-sale debt securities on a quarterly
basis to see if any unrealized loss is due to credit-related factors. Factors considered in determining whether an impairment is credit-related include
the extent to which the investment’s fair value is less than its cost basis, declines in published credit ratings, changes in interest rates, and any other
adverse factors related to the security. If it is determined that a credit-related impairment exists, the Company will measure the credit loss based on a
discounted cash flows model. Credit-related impairments on available-for-sale debt securities are recognized as an allowance for credit losses with a
corresponding adjustment to other income, net in the Company’s consolidated statement of operations. The unrealized loss position that is not credit-
related is recorded, net of any related tax effects, in other comprehensive income until realized. There were no credit-related losses recognized for
the periods presented.
The cost of securities sold is based on the specific-identification method. The amortized cost of securities is adjusted for amortization of premiums
and accretion of discounts to maturity. In accordance with our investment policy, management invests in money market funds, U.S. treasury
securities, corporate bonds, and commercial paper. The Company has not experienced any losses on its deposits of cash, cash equivalents, and
marketable securities.
Fair Value of Financial Instruments
The Company’s financial instruments include cash and cash equivalents, marketable securities, receivable from collaboration partner, current and
noncurrent prepaid expenses, accounts payable, and accrued liabilities. The Company’s financial instruments approximate fair value due to their
relatively short maturities.
The Company utilizes valuation techniques that maximize the use of observable inputs and minimize the use of unobservable inputs to the extent
possible. The Company determines the fair value of its financial instruments based on assumptions that market participants would use in pricing an
asset or liability in the principal or most advantageous market. When considering market participant assumptions in fair value measurements, the
following fair value hierarchy distinguishes between observable and unobservable inputs, which are categorized in one of the following levels:
Level 1 – Inputs are unadjusted, quoted prices in active markets for identical assets or liabilities at the measurement date;
Level 2 – Inputs are observable, unadjusted quoted prices in active markets for similar assets or liabilities, unadjusted quoted prices for
identical or similar assets or liabilities in markets that are not active, or other inputs that are observable or can be corroborated by observable
market data for substantially the full term of the related assets or liabilities; and
Level 3 – Unobservable inputs that are significant to the measurement of the fair value of the assets or liabilities that are supported by little or
no market data.
115
Property and Equipment
Property and equipment are stated at cost, net of accumulated depreciation and amortization. Depreciation and amortization is computed using the
straight-line method over the estimated useful lives of the respective assets, generally three to five years. Leasehold improvements are amortized
over the lesser of their useful lives or the remaining life of the lease. When assets are retired or otherwise disposed of, the cost and related
accumulated depreciation and amortization are removed from the consolidated balance sheet and the resulting gain or loss is reflected in the
consolidated statements of operations in the period realized. Maintenance and repairs are charged to the consolidated statements of operations as
incurred.
Leases
The Company determines whether an arrangement is or contains a lease at the inception of the lease. Leases are recognized on the balance sheet as
right-of-use assets and lease liabilities. Lease liabilities and their corresponding right-of-use assets are recorded based on the present value of lease
payments over the expected lease term. The Company utilizes the appropriate incremental borrowing rate, which is the rate incurred to borrow on a
collateralized basis over a similar term an amount equal to the lease payments in a similar economic environment. Certain adjustments to the right-
of-use asset may be required for items such as initial direct costs paid or incentives received and any prepaid or accrued rent. Rent expense for the
operating lease is recognized on a straight-line basis over the lease term and is included in operating expenses on the statements of operations and
comprehensive loss. Variable lease payments include lease operating expenses.
The Company excludes balance sheet recognition of operating leases having a term of 12 months or less (short-term leases) and does not separate
lease components and non-lease components for its long-term leases.
Impairment of Long-Lived Assets
The Company reviews long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset
may not be recoverable. Recoverability is measured by comparing the carrying amount to the future net undiscounted cash flows which the assets
are expected to generate. If the total of the undiscounted future cash flows is less than the carrying amount of the assets, an impairment loss is
recognized for the amount by which the carrying amount of the assets exceeds its fair value. For the years ended December 31, 2022 and 2021, the
Company did not recognize an impairment loss on its right-of-use assets. For the year ended December 31, 2020, the Company recognized a $0.2
million impairment loss related to its decision to no longer utilize certain property through the end of the lease term.
Revenue Recognition
The Company recognizes revenue when control of promised goods or services is transferred to customers in an amount that reflects the
consideration that is expected to be received for those goods or services. In determining the appropriate amount of revenue to be recognized as the
Company fulfills its obligations under arrangements, the Company performs the following steps: (i) identify the contract(s) with a customer, (ii)
identify the performance obligations in the contract, (iii) determine the transaction price, (iv) allocate the transaction price to the performance
obligations in the contract, and (v) recognize revenue when (or as) the entity satisfies the performance obligation. If it is determined that multiple
performance obligations exist, the transaction price is allocated at the inception of the agreement to all identified performance obligations based on
the relative standalone selling price (SSP). The relative SSP for each deliverable is estimated using external sourced evidence if it is available. If
external sourced evidence is not available, we use our best estimate of the SSP for the deliverable.
The Company recognizes collaboration revenue at a point in time if control of the promised good or service has been transferred to the customer.
The Company recognizes collaboration revenue over time by measuring the progress toward complete satisfaction of the performance obligation
using an input measure. In order to recognize revenue over the research and development period, the Company measures actual costs incurred to
date compared to the overall total expected costs to satisfy the performance obligation. Revenues are recognized as the program costs are incurred.
The Company re-evaluates the estimate of expected costs to satisfy the performance obligation each reporting period.
116
Research and Development Costs
Research and development costs are expensed as incurred and consist primarily of new product development. Research and development costs
include salaries and benefits, consultants’ fees, process development costs, stock-based compensation, and laboratory supplies, as well as fees paid
to third parties that conduct certain research and development activities on the Company’s behalf. In addition, research and development costs
include the reimbursable costs incurred for the collaboration agreements, which includes payroll costs for time incurred on projects, laboratory
supplies, and third-party research and development activities.
A substantial portion of the Company’s ongoing research and development activities are conducted by third-party service providers. The Company
records accrued expenses for estimated preclinical study and clinical trial expenses. Estimates are based on the services performed pursuant to
contracts with research institutions, CROs in connection with clinical studies, investigative sites in connection with clinical studies, vendors in
connection with preclinical development activities, and contract manufacturing organizations in connection with the production of materials for
clinical trials. Further, the Company accrues expenses related to clinical trials based on the level of patient enrollment and activity according to the
related agreement. The Company monitors patient enrollment levels and related activity to the extent reasonably possible and make judgments and
estimates in determining the accrued balance in each reporting period. If the Company underestimates or overestimates the level of services
performed or the costs of these services, actual expenses could differ from estimates. To date, the Company has not experienced significant changes
in its estimates of preclinical studies and clinical trial accruals.
Stock-based Compensation
Stock-based compensation is measured on the grant date based on the fair value of the awards. The fair value of options to purchase common stock
is measured using the Black-Scholes option-pricing model. Stock-based compensation associated with restricted stock units (RSUs) is based on the
fair value of the Company's common stock on the grant date, which equals the closing price of the Company's common stock on the grant date. The
Company recognizes expense over the vesting period of the awards. Expense for options and RSUs that vest based only on a service condition is
recognized on a straight-line basis.
In 2021, the Company granted RSUs with market conditions to certain executives. The fair value of RSUs with market conditions is estimated using
a Monte Carlo simulation model. Assumptions and estimates utilized in the model include the stock price on grant date, risk-free interest rate,
dividend yield, expected stock volatility, and estimated period to achieve the market condition. The expense is recognized based on continued
employment of the participants, regardless of achievement of the market condition. Expense related to the RSUs with market conditions is
recognized using the accelerated attribution method.
The Company accounts for forfeitures as they occur for all awards.
Comprehensive Loss
Comprehensive loss includes net loss and certain changes in stockholders’ equity that are the result of transactions and economic events other than
those with stockholders. The Company’s only element of other comprehensive loss was net unrealized gain (loss) on marketable securities.
Income Taxes
The Company accounts for income taxes under the asset and liability method, which requires the recognition of deferred tax assets and liabilities for
the expected future tax consequences of events that have been included in the financial statements. Under this method, deferred tax assets and
liabilities are determined based on the differences between the financial statement and tax bases of assets and liabilities and are measured using
enacted tax rates and laws that will be in effect when the differences are expected to reverse. The effect of a change in tax rates on deferred tax
assets and liabilities is recognized in income in the period that includes the enactment date.
The deferred tax assets are recognized to the extent the Company believes that these assets are more likely than not to be realized. A valuation
allowance is provided when it is more likely than not that some portion or all of a deferred tax asset will not be realized. Due to the Company’s
historical operating performance and the
117
recorded cumulative net losses in prior periods, the net deferred tax assets have been fully offset by a valuation allowance.
The Company records uncertain tax positions using a two-step process. First, the Company determines whether it is more likely than not that the tax
positions will be sustained on the basis of the technical merits of the position. Second, for those tax positions that meet the more-likely-than-not
recognition threshold, the Company recognizes the largest amount of tax benefit that is more than 50% likely to be realized upon ultimate settlement
with the related tax authority.
The Company recognizes interest and penalties related to unrecognized tax benefits on the interest expense line and other expense line, respectively,
in the accompanying statements of operations. To date, there have been no interest or penalties charged in relation to the unrecognized tax benefits.
Employee 401(k) Plan
The Company has a qualified contributory savings plan under Section 401(k) of the Internal Revenue Code (the “Code”) covering substantially all
U.S. employees of Alector. The 401(k) plan is designed to provide tax-deferred retirement benefits in accordance with the provisions of Section
401(k) of the Code. Eligible employees may defer up to 100% of their eligible compensation up to the annual maximum as determined by the
Internal Revenue Service. The Company’s contributions to the plan are discretionary. For the years ended December 31, 2022, 2021, and 2020, the
Company made matching contributions of $1.2 million, $0.8 million, and $0.7 million, respectively.
Segments
The Company operates in one segment. The Company’s chief operating decision maker, its Chief Executive Officer, manages the Company’s
operations on a consolidated basis for purposes of allocating resources.

The Company’s Level 2 securities are valued using third-party pricing sources. The pricing services utilize industry standard valuation models for
which all significant inputs are observable. The Company classifies marketable securities available to fund current operations as current assets. As
of December 31, 2022, the remaining contractual maturities of $640.8 million of investments were less than one year and $9.6 million of investment
were after one year through two years. As of December 31, 2022, fifteen U.S. government treasury securities with an aggregate fair value of $133.2
million and an aggregate unrealized loss of $3.1 million were in a loss position for more than twelve months. The Company does not intend to sell
the investments that are currently in an unrealized loss position, and it is highly unlikely that the Company will be required to sell the investments
before recovery of their amortized cost basis, which may be at maturity. The Company did not sell any marketable securities for the years ended
December 31, 2022 and 2020. For the year ended December 31, 2021, the Company sold marketable securities for the total proceeds of $10.7
million for an immaterial realized gain based on the specific identification method.
4. Collaboration Agreements
GSK
On July 1, 2021, the Company entered into a Collaboration and License Agreement with Glaxo Wellcome UK Limited, a subsidiary of
GlaxoSmithKline plc (GSK), pursuant to which the Company and GSK collaborate on the global development and commercialization of
progranulin-elevating monoclonal antibodies, including latozinemab (also referred to as AL001), and AL101 (GSK Agreement). The GSK
Agreement was made effective on August 17, 2021.
Under the terms of the GSK Agreement, the Company received $700 million in upfront payments, of which $500 million was received in August
2021 and $200 million was received in January 2022. In addition, based on the development and commercialization plan for latozinemab and
AL101, the Company may be eligible to receive up to an additional $1.5 billion in clinical development, regulatory, and commercial launch-related
milestone payments. In the United States, the Company and GSK will equally share profits and losses from
119
commercialization of latozinemab and AL101. Outside of the United States, the Company will be eligible for double-digit tiered royalties.
The Company and GSK will jointly develop latozinemab and AL101, with GSK conducting Phase 3 clinical trials for Alzheimer’s disease and
Parkinson’s disease and other non-orphan indications. The Company and GSK will share development costs 60% by GSK and 40% by the
Company, except that the Company will solely bear the development costs of the initial Phase 2 clinical trials under the development plan, and the
parties will share manufacturing development costs equally.
The Company concluded that the GSK Agreement is within the scope of ASC 808, Collaborative Arrangements, as both parties are active
participants in the activities and are exposed to significant risks and rewards dependent on the success of the commercialization of AL001 and
AL101. Certain elements are required to be accounted for under ASC 606, Revenue From Contracts With Customers, where the counterparty is a
customer for a good or service that is a distinct unit of account.
The Company determined that the distinct performance obligations under ASC 606 consisted of: (i) license and know-how to AL001 FTD-GRN,
which is currently in Phase 3 clinical development and (ii) the research and development activities, including license rights and know-how, relating
to products in Phase 2 or earlier stages of development.
The transaction price at inception and as of December 31, 2022, included fixed consideration consisting of the upfront payments of $700 million.
All potential future milestones and other payments were considered constrained at the inception of the GSK Agreement and as of December 31,
2022, since the Company could not conclude it was probable that a significant reversal in the amount of revenue recognized would not occur.
The respective standalone value for each of the performance obligations was allocated to the transaction price. The estimated SSP of each
performance obligation was determined using discounted cash flows from the expected commercialization of AL001 and AL101 and estimated
research and development costs to be incurred by the Company in the initial Phase 2 clinical trials. The estimate of SSP for each performance
obligation reflects management's assumptions, which may include forecasted revenues, development timelines, discount rates, and probabilities of
technical and regulatory success. For the license for FTD-GRN, the Company determined that GSK could benefit from the license at the time the
license was granted and therefore, the related performance obligation was satisfied at a point in time. For the product candidates in Phase 2 or earlier
stages of development, the Company determined that GSK could not benefit from the licenses without the corresponding development services that
the Company has committed to perform due the earlier stage of development for these licenses. Except where agreed to otherwise, the Company will
perform research and development activities through the end of the initial Phase 2 clinical trials. Revenue will be recognized over time as the
research and development activities are performed. The Company will measure progress based on actual costs incurred to date compared to the
overall total expected costs to satisfy the performance obligations.
The research and development activities for products in Phase 3 clinical development were determined to be within the scope of ASC 808. Both
parties will be active participants in the development, manufacturing, and commercialization of the product and are exposed to significant risks and
rewards that are dependent on the commercial success of the products. The Company and GSK participate in profit and loss sharing for each
program commensurate with each party's cost-sharing responsibilities during research and development. ASC 808 does not provide recognition and
measurement guidance. As such, the Company determined that ASC 730, Research and Development, was appropriate to analogize to based on the
nature of the cost-sharing provision of the agreement. The Company has concluded that payments to or reimbursements from GSK related to these
services will be accounted for as an increase to or reduction of research and development expenses, respectively.
Collaboration revenue under the GSK Agreement during the year ended December 31, 2022 and 2021, was $62.9 million and $192.1 million,
respectively. The deferred revenue related to the GSK Agreement was $444.9 million and $307.9 million as of December 31, 2022 and 2021. The
deferred revenue is expected to be recognized over the research and development period of the programs through the completion of initial Phase 2
clinical trials.
120
Costs associated with co-development activities performed under the agreement are included in research and development expenses in the
consolidated statements of operations, with any reimbursement of costs by GSK reflected as a reduction of such expenses. For the year ended
December 31, 2022 and 2021, the Company recognized a reduction of research and development expense of $14.7 million and $8.8 million,
respectively, under the GSK Agreement.
AbbVie
The Company entered into an agreement in October 2017 with AbbVie Biotechnology, Ltd. (AbbVie) to co-develop antibodies to two program
targets in preclinical development (AbbVie Agreement). Under the terms of the AbbVie Agreement, AbbVie made $205.0 million in upfront
payments, of which $5.0 million and $200.0 million were received by the Company in October 2017 and January 2018, respectively. The Company
was to perform research and development services for the two programs through the end of Phase 2 clinical trials, which were each considered to be
separate performance obligations. AbbVie decided to terminate one of the two collaboration programs, the CD33 collaboration program, after
AbbVie and Alector collaboratively reviewed next steps for AL003, the asset being developed under that program, and concluded that further
development of AL003 was not warranted. AbbVie provided written notice to terminate the CD33 collaboration program on June 30, 2022. The
Company will no longer continue development of this program and will not be eligible for any future milestones related to that program from
AbbVie. The Company continues to develop the AL002 program under the AbbVie Agreement. AbbVie has the exclusive right to exercise an option
under the AbbVie Agreement with the Company for $250.0 million. If AbbVie exercises its option for the AL002 program, AbbVie would take over
the development beginning with Phase 3 clinical trials, and the product candidates program costs will be split between the parties. The Company
would also share in profits and losses upon commercialization of any products. However, following AbbVie’s exercise of its option for the AL002
program, the Company may opt out of sharing in development costs and profits or losses for that program and instead receive tiered royalties. In
February 2023, the Company and AbbVie amended the AbbVie agreement, which will result in the Company receiving a $17.8 million milestone
payment for the dosing of the first patient in a long-term extension study. Additionally, under the terms of the AbbVie Agreement, the Company will
be eligible to earn up to an additional $225.0 million in milestone payments related to the regulatory approval for up to three indications. The
Company assessed its collaboration agreement with AbbVie in the context of the delivery of the research and development services.
The transaction price at inception and as of December 31, 2022, included fixed consideration consisting of the upfront payments of $205 million.
All potential future milestones and other payments were considered constrained at the inception of the AbbVie Agreement and as of December 31,
2022, since the Company could not conclude it was probable that a significant reversal in the amount of revenue recognized would not occur.
Collaboration revenue under the AbbVie Agreement during the years ended December 31, 2022, 2021, and 2020 was $70.7 million, $14.9 million,
and $21.1 million, respectively. The deferred revenue related to the AbbVie Agreement was $46.7 million and $117.4 million as of December 31,
2022 and 2021, respectively. The deferred revenue is expected to be recognized over the research and development period of the programs through
the AL002 program through the completion of Phase 2 clinical trials. For the year ended December 31, 2022, we recorded a net increase to
collaboration revenue under the AbbVie Agreement due to changes in estimated costs to satisfy the performance obligations resulting from the
termination of the AL003 program, partially offset by increases in total expected costs for the AL002 program.
Innovent
The Company entered into an agreement in March 2020 with Innovent Biologics (Innovent) to license, develop, and commercialize AL008 in China
(Innovent Agreement). AL008 is the Company’s novel antibody targeting the CD47-SIRP-alpha pathway, a potent survival pathway co-opted by
tumors to evade the innate immune system. Under the terms of the Innovent Agreement, Innovent would pay the Company up to $11.5 million in
development milestones, $112.5 million in sales milestones, and future royalties on sales and the Company would retain the rights to develop and
commercialize AL008 outside of China. The Company determined there is one performance obligation for the delivery of the license and will
recognize revenue when it is probable that there will not be significant reversal of cumulative revenue. Development and sales milestones under the
Innovent Agreement were not included in the transaction price, as all these amounts were
121
fully constrained as of December 31, 2022. As of December 31, 2022, no revenue has been recognized and no payments have been received under
the Innovent Agreement.

Leases
In June 2018, the Company signed a lease agreement to lease approximately 105,000 square feet in office and laboratory space in South San
Francisco which serves as the Company’s headquarters (the “Headquarters”). The lease expires in 2029 with an option to renew for a period of ten
years. The landlord paid for $15.7 million of tenant improvements. In connection with the lease, the Company entered into a letter of credit
arrangement in the amount of $1.5 million as collateral for the lease, which is classified as restricted cash on the consolidated balance sheets. In
October 2020, the Company signed a lease agreement to lease approximately 18,700 square feet of office and laboratory space in Newark,
California. The lease term ends on February 6, 2028 with an option to extend for an additional five years. The landlord is obligated to pay for up to
$0.4 million of tenant improvements. The measurement of the lease liabilities for the leases excludes the options to extend the term of the lease as
such extensions are not reasonably certain to occur. Variable lease costs for all of the Company’s leases consist of operating expenses for the spaces.
In May 2019, the Company entered into an agreement to sublease approximately 25,000 square feet of the Headquarters (the “Sublease”), which
was amended to approximately 23,600 square feet in December 2020. The Sublease expired in November 2021. The sublessee pays its proportionate
share of operating expenses for the space.
In November 2021, the Company entered into an agreement to sublease approximately 7,132 square feet of the Headquarters, which was amended in
May 2022 to include an additional space of 13,150 square feet. The
122
7,132 square feet of space subleased expired in December 2022 and the additional space will expire in November 2023.

Determination of Fair Value
The estimated grant-date fair value of all the Company’s options to purchase common stock was calculated using the Black-Scholes option pricing
model, based on the following assumptions:
Expected term (in years)
Expected volatility
Risk free interest rate
Dividend yield
2022
5.3– 6.1
79% – 80%
1.5% – 4.3%
—
Year Ended December 31,
2021
5.2 – 6.1
78% – 81%
0.5% – 1.3%
—
2020
5.3 – 6.1
74% – 78%
0.3% – 1.8%
—
The fair value of each stock option was determined by the Company using the methods and assumptions discussed below. Each of these inputs is
subjective and generally requires significant judgment and estimation by management.
Expected Term—The expected term represents the period that stock-based awards are expected to be outstanding. The expected term was
derived by using the simplified method which uses the midpoint between the average vesting term and the contractual expiration period of
the stock-based award.
Expected Volatility—The Company has limited information on the volatility of stock options as the shares were not actively traded on any
public markets prior to February 7, 2019. The expected volatility was derived from the historical stock volatilities of comparable peer public
companies within its industry. These companies are considered to be comparable to the Company’s business over a period equivalent to the
expected term of the stock-based awards. In 2020, the Company began giving weight to in its own historical volatility in the determination of
expected volatility.
Risk-Free Interest Rate—The risk-free interest rate is based on the U.S. Treasury yield curve in effect at the date of grant for zero-coupon
U.S. Treasury notes with maturities approximately equal to the expected term.
Expected Dividend Rate—The expected dividend is zero as the Company has not paid nor does it anticipate paying any dividends on its
common stock underlying its stock options in the foreseeable future.
2019 Equity Incentive Plan and 2022 Inducement Plan
On February 6, 2019, the Company adopted the 2019 Equity Incentive Plan (2019 Plan) under which the Board may issue incentive stock options,
nonstatutory stock options, restricted stock, restricted stock units, stock appreciation rights, performance units, and performance shares to the
Company’s employees, directors, and consultants. The Company’s 2017 Stock Option and Grant Plan (2017 Plan) was terminated; however, shares
subject to awards granted under it will continue to be governed by the 2017 Plan. Shares reserved for issuance but not issued pursuant to, or not
subject to, awards granted under the 2017 Plan were added to the available shares in the 2019 Plan. Shares subject to awards granted under the 2017
Plan that are repurchased by, or forfeited to, the Company will also be reserved for issuance under the 2019 Plan. The board of directors, or a
committee appointed by the board of directors, has the authority to determine to whom options or shares will be granted, the number of shares, the
term, and the exercise price. If an individual owns stock representing 10% or more of the outstanding shares, the exercise price of each share shall
be at least 110% of the fair market value and the term of the award shall not exceed five years. All other options granted under the 2019 Plan must
have an exercise price at least equal to the fair market value on the date of grant and have a term not to exceed ten years. The stock options generally
vest over a four-year period with one forty-eighth of the shares vesting each month or over a four-year period with 25% vesting at the one-year cliff
and monthly thereafter. The RSUs generally vest over a period of three years with one-twelfth of the shares vesting quarterly. On January 1, 2022,
the Company added 4,099,309 shares to the shares reserved for issuance under the 2019 Equity Incentive Plan. As of December 31, 2022, the
Company had reserved 20,463,901 shares of the automatic conversion provision of common stock under the 2019 Plan, of which 5,587,550 shares
were available for issuance of future awards.
124
On January 1, 2022, the Company adopted the 2022 Inducement Plan (Inducement Plan) and reserved 1,630,000 shares for issuance under the
Inducement Plan for the grant of equity-based awards to individuals who were not previously employees or non-employee directors of the Company.
On September 22, 2022, the Company increased the number of shares available for issuance under the 2022 Inducement Plan to a total of 3,300,000
shares. As of December 31, 2022, 1,401,483 shares were available for issuance of future awards under the Inducement Plan.

The aggregate intrinsic value is calculated as the difference between the exercise price of the underlying stock options and the fair value of the
Company’s common stock for stock options that were in-the-money. The aggregate intrinsic value of options exercised was $1.2 million, $37.1
million, and $11.1 million for the years ended December 31, 2022, 2021, and 2020, respectively. The weighted-average grant-date fair value per
share of options granted was $8.42, $14.70, and $10.14, for the years ended December 31, 2022, 2021, and 2020, respectively. As of December 31,
2022, total unrecognized stock-based compensation related to unvested stock options was $64.4 million, which the Company expects to recognize
over a remaining weighted-average period of 2.7 years.
Restricted Stock Activity
Activity for the restricted stock awards and RSUs is shown below. In May 2021 and January 2022, the Company issued RSUs with market
conditions to certain executives, which are also included in the table below. The RSUs with market conditions are earned based on stock price
performance and continued service by the employee. The RSUs with market conditions trigger vesting upon the company's stock price attaining a
specified level over a specified period of time. The shares then vest quarterly over one year after attainment. The Company used a Monte Carlo
simulation model to determine the fair value of the awards at the grant date. The Monte Carlo model uses the fair value inputs on the grant date to
run simulations and take an average of possible outcomes. The total grant date fair value of the RSUs with market condition was $6.6 million to be
amortized over an estimated weighted average service period of 2.1 years. Compensation expense related to awards with market-based conditions is
recognized regardless of whether the market condition is ultimately satisfied if the related service has been provided.

2019 Employee Stock Purchase Plan
The 2019 Employee Stock Purchase Plan (2019 ESPP) enables eligible employees of the Company to purchase shares of common stock at a
discount. Each offering period is approximately six months long beginning on the first trading day on or after June 1 and December 1 each year.
ESPP participants purchase shares of common stock at a price per share equal to 85% of the lesser of (1) the fair market value per share of the
common stock on the first trading day of the offering period or (2) the fair market value of the common stock on the purchase date. On January 1,
2022, 591,397 shares were added to the shares reserved for issuance under the 2019 ESPP pursuant to the annual automatic increase. As of
December 31, 2022, there was $0.4 million in unrecognized compensation expense related to the 2019 ESPP to be recognized over five months.

In assessing the realization of deferred tax assets, management considers whether it is more likely than not that some portion or all of the deferred
assets will be realized. The ultimate realization of the deferred tax assets is dependent upon the generation of future taxable income during the
periods in which those temporary differences become deductible. Evaluating the need for a valuation allowance for deferred tax assets often requires
judgment and analysis of all the positive and negative evidence available, including cumulative losses in recent years and projected future taxable
income, to determine whether all or some portion of the deferred tax assets will not be realized. As of December 31, 2022, the Company has utilized
a full valuation allowance to offset the net deferred tax assets as the Company believes it is not more likely than not that the net deferred tax assets
will be fully realizable. The valuation allowance for deferred tax assets increased by $42.3 million during the year ended December 31, 2022.
As of December 31, 2022, the Company had federal and state net operating loss (NOL) carryforwards of approximately $40.3 million and $203.5
million, respectively. Federal NOL carryforwards have an indefinite life and deductions cannot exceed 80% of taxable income. State NOL
carryforwards will begin to expire as early as 2030, if not utilized, or have an indefinite life. As of December 31, 2022, the Company also had
federal and California tax credit carryforward of approximately $28.4 million and $11.6 million, respectively. The federal tax credits will begin to
expire in 2036 while the California tax credits have no expiration date.
127
Generally, utilization of the NOL carryforwards and credits may be subject to an annual limitation due to the ownership change limitations provided
by Section 382, which provides for limitations on NOL carryforwards and certain built-in losses following ownership changes, and Section 383,
which provides for special limitations on certain excess credits, etc., of the Code, and similar state provisions. Accordingly, the Company’s ability to
utilize NOL carryforwards may be limited as the result of such an “ownership change.” The carryforwards could be subject to an annual limitation,
resulting in a reduction in the gross deferred tax assets before considering the valuation allowance. Further, a portion of the carryforwards may
expire before being applied to reduce future earnings. The Company is not aware of any changes in ownership that would result in material
limitations under Section 382 at this time.
The following table summarizes the activity related to the Company’s unrecognized tax benefits for the years ended December 31, 2022, 2021, and

If the unrecognized tax benefits for uncertain tax positions as of December 31, 2022, is recognized, there will be no impact to the effective tax rate
as the tax benefit would increase the net deferred tax assets, which is currently offset with a full valuation allowance. The Company’s policy is to
include interest and penalties related to unrecognized tax benefits, if any, within the provision for taxes in the consolidated statements of operations.
The Company did not accrue any interest or penalties and does not have any tax positions for interest or penalties for the year ended December 31,
2022. The Company does not have any tax positions for which it is reasonably possible that the total amount of gross unrecognized tax benefits will
significantly change within 12 months of December 31, 2022.
The Company recognizes the tax benefit of an uncertain tax position only if it is more likely than not that the position is sustainable upon
examination by the taxing authority, based on the technical merits. During the years ended December 31, 2022 and 2021, the Company recorded an
uncertain tax position of $8.2 million and $2.4 million, respectively. The income tax provision for the years ended December 31, 2022 and 2021,
included a reversal of reserves on uncertain tax provisions of zero and $0.1 million. The Company’s income tax returns generally remain subject to
examination by federal and most state tax authorities. The Company is currently not subject to any income tax audits by federal or state taxing
authorities. The statute of limitations for tax liabilities for all years remains open.

Related Party Transactions
In 2014, the Company entered into a collaboration agreement with Adimab, LLC (Adimab) under which the Company is developing antibodies
discovered by Adimab in its latozinemab and AL101 programs and is developing antibodies optimized by Adimab in its AL002 program (2014
Adimab Agreement). The 2014 Adimab Agreement also provided for the Company’s development of antibodies optimized by Adimab in its AL003
program. However, AbbVie decided to terminate the CD33 collaboration program, after AbbVie and Alector collaboratively reviewed next steps for
AL003, the asset being developed under that program, and concluded that further development of AL003 was not warranted. In August 2019, the
Company signed a collaboration agreement with Adimab for research and development of additional antibodies (2019 Adimab Agreement). In
December 2021, the Company signed another collaboration agreement with Adimab for antibody engineering research programs (2021 Adimab
Agreement). The 2021 Adimab agreement expired at the end of the option period for the research program that was conducted under the agreement.
The former Chief Executive Officer of Adimab through May 2022 is a Co-founder and Chairperson of the board of directors of Alector. For the
years ended December 31, 2022, 2021, and 2020, Alector incurred expenses of
128
$0.2 million, $1.0 million, and zero for milestone payments for progress of programs through clinical trials and other expenses. The Company had
no accrued liabilities due to Adimab as of December 31, 2022 and 2021. Under the 2014 Adimab Agreement, the Company has made milestone
payments and will owe low- to mid- single-digit royalty payments for commercial sales of the product candidate. Under the 2019 Adimab
Agreements, the Company will owe certain milestone payments and low single-digit royalty payments for commercial sales of covered product
candidates.

performed an evaluation of the effectiveness of the design and operation of our disclosure controls and procedures as defined in Rules 13a-15(e) and 15d-
15(e) of the Exchange Act. Our disclosure controls and procedures are designed to ensure that information required to be disclosed in the reports we file or
submit under the Exchange Act is recorded, processed, summarized, and reported within the time periods specified in the SEC’s rules and forms, and that
such information is accumulated and communicated to our management, including the Principal Executive Officer and the Principal Financial and
Accounting Officer, to allow timely decisions regarding required disclosures. Any controls and procedures, no matter how well designed and operated, can
provide only reasonable assurance of achieving the desired control objective and management necessarily applies its judgment in evaluating the cost-
benefit relationship of possible controls and procedures. Based on this evaluation, our Principal Executive Officer and Principal Financial and Accounting
Officer concluded that, as of December 31, 2022, the design and operation of our disclosure controls and procedures were effective at a reasonable
assurance level.
Changes in Internal Control over Financial Reporting
There were no changes in our internal control over financial reporting during the quarter ended December 31, 2022, that have materially affected, or
are reasonably likely to materially affect, our internal control over financial reporting.
Management’s Report on Internal Control over Financial Reporting
Our management is responsible for establishing and maintaining adequate internal control over financial reporting (as defined in Rule 13a-15(f)
under the Exchange Act) to provide reasonable assurance regarding the reliability of our financial reporting and the preparation of consolidated financial
statements for external purposes in accordance with generally accepted accounting principles. Under the supervision of and with the participation of our
principal executive officer and principal financial officer, our management assessed the effectiveness of our internal control over financial reporting as of
December 31, 2022 based on the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission in “Internal Control—
Integrated Framework” (2013). Based on this assessment, management concluded that our internal control over financial reporting was effective as of
December 31, 2022.
The effectiveness of our internal control over financial reporting as of December 31, 2022 has been audited by Ernst & Young LLP, an independent
registered public accounting firm, as stated in their report which is included herein.
Report of Independent Registered Public Accounting Firm
To the Stockholders and the Board of Directors of Alector, Inc.
Opinion on Internal Control Over Financial Reporting
We have audited Alector, Inc.'s internal control over financial reporting as of December 31, 2022, based on criteria established in Internal Control—
Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework) (the COSO criteria). In our
opinion, Alector, Inc. (the Company) maintained, in all material respects, effective internal control over financial reporting as of December 31, 2022, based
on the COSO criteria.
130
We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the
consolidated balance sheets of the Company as of December 31, 2022 and 2021, the related consolidated statements of operations and comprehensive loss,
stockholders’ equity and cash flows for each of the three years in the period ended December 31, 2022, and the related notes, and our report dated February
28, 2023 expressed an unqualified opinion thereon.
Basis for Opinion
The Company’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the
effectiveness of internal control over financial reporting included in the accompanying Management’s Report on Internal Control over Financial Reporting.
Our responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit. We are a public accounting firm
registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the
applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.
We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects.
Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing
and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered
necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.
Definition and Limitations of Internal Control Over Financial Reporting
A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial
reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s
internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail,
accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded
as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures
of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance
regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the
financial statements.
Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any
evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree
of compliance with the policies or procedures may deteriorate.

Exhibit 10.11
ALECTOR, INC.
OUTSIDE DIRECTOR COMPENSATION POLICY
(As amended on March 17, 2022)
Alector, Inc. (the “Company”) believes that providing cash and equity compensation to members of its Board of
Directors (the “Board,” and members of the Board, the “Directors”) represents an effective tool to attract, retain and reward
Directors who are not employees of the Company (the “Outside Directors”). This Outside Director Compensation Policy (the
“Policy”) formalizes the Company’s policy regarding cash compensation and grants of equity awards to its Outside Directors.
Unless otherwise defined herein, capitalized terms used in this Policy will have the meaning given such term in the Company’s
2019 Equity Incentive Plan, as amended from time to time (the “Plan”), or if the Plan is no longer in use at the time of an equity
award, the meaning given such term or any similar term in the equity plan then in place under which such equity award is
granted. Each Outside Director will be solely responsible for any tax obligations incurred by such Outside Director as a result of
the equity and cash payments such Outside Director receives under this Policy.
Subject to Section 9, this Policy will be effective as of the effective date of the registration statement in connection with
the initial public offering of the Company’s securities (the “Registration Statement”) (such date, the “Effective Date”).
1. CASH COMPENSATION
Annual Cash Retainer
Each Outside Director will be paid an annual cash retainer of $40,000. There are no per‑meeting attendance fees for
attending Board meetings.
Committee Annual Cash Retainer
As of the Effective Date, each Outside Director who serves as the chairman of the Board, the lead Outside Director, or
the chair or a member of a committee of the Board will be eligible to earn additional annual fees (paid quarterly in arrears on a
prorated basis) as follows:
Non-Executive Chairman of the Board:
Lead Outside Director:
Chairman of Audit Committee:
Member of Audit Committee:
Chairman of Compensation Committee:
Member of Compensation Committee:
Chairman of Nominating and Governance Committee:
Member of Nominating and Governance Committee:

5,000
For clarity, each Outside Director who serves as the chair of a committee will receive only the annual fee as the chair of
the committee and will not also receive the additional annual fee as a member of the committee.
Payment
Each annual cash retainer under this Policy will be paid quarterly in arrears on a prorated basis to each Outside Director
who has served in the relevant capacity at any point during the immediately preceding fiscal quarter, and such payment shall be
made no later than 30 days following the end of such immediately preceding fiscal quarter. For purposes of clarification, an
Outside Director who has served as an Outside Director, as a member of an applicable committee (or chair thereof) during only a
portion of the relevant Company fiscal quarter will receive a pro-rated payment of the quarterly payment of the applicable annual
cash retainer(s), calculated based on the number of days during such fiscal quarter such Outside Director has served in the
relevant capacities. For purposes of clarification, an Outside Director who has served as an Outside Director, as a member of an
applicable committee (or chair thereof), as applicable, from the Effective Date through the end of the fiscal quarter containing the
Effective Date (the “Initial Period”) will receive a prorated payment of the quarterly payment of the applicable annual cash
retainer(s), calculated based on the number of days during the Initial Period that such Outside Director has served in the relevant
capacities.
2. EQUITY COMPENSATION
Outside Directors will be eligible to receive all types of Awards (except Incentive Stock Options, Performance Units or
Performance Shares) under the Plan (or the applicable equity plan in place at the time of grant), including discretionary Awards
not covered under this Policy. All grants of Awards to Outside Directors pursuant to Section 2 of this Policy will be automatic
and
nondiscretionary, except as otherwise provided herein, and will be made in accordance with the following provisions:
(a) No Discretion. No person will have any discretion to select which Outside Directors will be granted any Awards
under this Policy or to determine the number of Shares to be covered by such Awards.
(b) Initial Options. Subject to Section 11 of the Plan, each individual who first becomes an Outside Director following
the Effective Date will be granted a nonstatutory stock option (an “Initial Option”) having a grant date fair value of
approximately $550,000. The number of options will be determined by dividing the dollar value of the grant by the Black Scholes
value of a share (with the shares covered by the award rounded down to the nearest whole share). The Initial Option will be made
on the first trading date on or after the date on which such individual first becomes an Outside Director, whether through election
by the stockholders of the Company or appointment by the Board to fill a vacancy. If an individual was a member of the Board
and also an employee, becoming an Outside Director due to termination of employment will not entitle the Outside Director to an
Initial Option. Each Initial Option will vest as to 1/48th of the Shares subject to the Initial Option on the one-month anniversary
of the date the applicable Outside Director’s service as an Outside Director commenced and as to 1/48th of the Shares subject to
the Initial Option each month thereafter, in each case subject to the Outside Director continuing to be a Service Provider through
the applicable vesting date. Each Initial Option will become fully vested and exercisable immediately prior to a Change in
Control, subject to the Outside Director continuing to be a Service Provider at the time of the Change in Control.
(c) Annual Award. Subject to Section 11 of the Plan, on the date of each annual meeting of the Company’s stockholders
following the Effective Date (each, an “Annual Meeting”), each Outside Director who, as of such annual meeting date, has
served on the board as a director for at least the preceding six months, will be automatically granted a nonstatutory stock option
(“NSOs”) and restricted stock units (“RSUs”) (collectively, the “Annual Award”) having an aggregate grant date fair value of
approximately $350,000. The number of NSOs will be determined by dividing the dollar value of the grant by the Black Scholes
value of a Share (with the shares covered by the award rounded down to the nearest whole share). The Black Scholes factor will
be averaged over the 30-days prior to the grant date of the Annual Award, as determined in accordance with the Company’s then-
current accounting principles. The number of RSUs will be determined by a 2:1 NSO to RSU conversation ratio. As a result, the
number of Shares subject to the RSUs will be one half of the number of Shares that would be subject to the NSOs granted on the
same date. Accordingly, the value of the Annual Award will be split equally (50%-50%) between NSOs and RSUs.
Each Annual Option Award will vest on as to 1/12th of the Shares subject to the Annual Option each month after the date
the Annual Option is granted, provided that the Annual Option will vest in full on the earlier of (i) the 12-month anniversary of
the date of grant, or (ii) the date of the next regularly scheduled Annual Meeting, in each case subject to the Outside Director
continuing to be a Service Provider through the applicable vesting date. Each Annual Option will become fully vested and
exercisable immediately prior to a Change in Control, subject to the Outside Director continuing to be a Service Provider.
Each Annual RSU Award will vest in full on the earlier of (i) the 12-month anniversary of the date of grant, or (ii) the
date of the next regularly scheduled Annual Meeting, in each case subject to the Outside Director continuing to be a Service
Provider through the applicable vesting date. Each Annual Option will become fully vested and exercisable immediately prior to
a Change in Control, subject to the Outside Director continuing to be a Service Provider.
(d) Additional Terms of Initial Options and NSOs. The terms and conditions of each Initial Option and NSOs will be
as follows:
Plan.
(i) The term of each Initial Option and NSOs will be ten years, subject to earlier termination as provided in the
(ii) Each Initial Option and NSOs will have an exercise price per Share equal to 100% of the Fair Market
Value per Share on the grant date.
(e) Value. For purposes of this Policy, “Value” means the grant date fair value (determined in accordance with U.S.
generally accepted accounting principles), or such other methodology the Board may determine prior to the grant of the Initial
Option or Annual Award becoming effective, as applicable.
3. CHANGE IN CONTROL
In the event of a Change in Control, each Outside Director will fully vest in his or her outstanding Company equity
awards, including any Initial Option or Annual Award, provided that the Outside Director continues to be an Outside Director
through such date.
4. ANNUAL COMPENSATION LIMIT
No Outside Director may be paid, issued or granted, in any fiscal year, cash compensation and Awards with an aggregate
value greater than $750,000, increased to $1,000,000 in the fiscal year of his or her initial service as an Outside Director (with the
value of each Award based on its Grant Value for purposes of the limitation under this Section 4). Any cash compensation paid
or Awards granted to an individual for his or her services as an Employee, or for his or her services as a Consultant (other than as
an Outside Director), will not count for purposes of the limitation under this Section 4.
5. TRAVEL EXPENSES
Each Outside Director’s reasonable, customary and documented travel expenses to Board meetings will be reimbursed
by the Company.
6. ADDITIONAL PROVISIONS
All provisions of the Plan not inconsistent with this Policy will apply to Awards granted to Outside Directors.
7. ADJUSTMENTS
In the event that any dividend or other distribution (whether in the form of cash, Shares, other securities or other
property), recapitalization, stock split, reverse stock split, reorganization, merger, consolidation, split-up, spin-off, combination,
repurchase, or exchange of Shares or other securities of the Company, or other change in the corporate structure of the Company
affecting the Shares occurs, the Administrator, in order to prevent diminution or enlargement of the benefits or potential benefits
intended to be made available under this Policy, will adjust the number of Shares issuable pursuant to Awards granted under this
Policy.
8. SECTION 409A
In no event will cash compensation or expense reimbursement payments under this Policy be paid after the later of (i) the
15th day of the 3rd month following the end of the Company’s fiscal year in which the compensation is earned or expenses are
incurred, as applicable, or (ii) the 15th day of the 3rd month following the end of the calendar year in which the compensation is
earned or expenses are incurred, as applicable, in compliance with the “short-term deferral” exception under Section 409A of the
Internal Revenue Code of 1986, as amended, and the final regulations and guidance thereunder, as may be amended from time to
time (together, “Section 409A”). It is the intent of this Policy that this Policy and all payments hereunder be exempt from or
otherwise comply with the requirements of Section 409A so that none of the compensation to be provided hereunder will be
subject to the additional tax imposed under Section 409A, and any ambiguities or ambiguous terms herein will be interpreted to
be so exempt or comply. In no event will the Company reimburse an Outside Director for any taxes imposed or other costs
incurred as a result of Section 409A.
9. REVISIONS
The Board may amend, alter, suspend or terminate this Policy at any time and for any reason. No amendment, alteration,
suspension or termination of this Policy will materially impair the rights of an Outside Director with respect to compensation that
already has been paid or awarded, unless otherwise mutually agreed between the Outside Director and the Company.
Termination of this Policy will not affect the Board’s or the Compensation Committee’s ability to exercise the powers granted to
it under the Plan with respect to Awards granted under the Plan pursuant to this Policy prior to the date of such termination.
*** Certain information has been excluded from this agreement because it is both (i) not material and (ii) would be competitively harmful if publicly
