Dear Shareholder,  

Thank you for your continued support as our management directs Phio Pharma in becoming an emerging and 
significant dynamic factor in the immuno-oncology therapy space. We have made significant progress toward 
this objective during the past year, by developing innovative therapeutics grounded on our clinically proven 
gene silencing technology -- self-delivering RNAi.   

We now have a unique, well-defined strategy in place (see below) driven by our talented, experienced and 
focused team.  They are diligently producing results to achieve significant value creation with our proprietary 
technology over the next 18 months. We very much appreciate your sustained support which has permitted 
us  to  assemble  this  quality  team.    Despite  our  robust  progress  in  immuno-oncology  thus  far,  the  broader 
investor community has yet to recognize Phio Pharmaceuticals’ potential value. Management conversely and 
strongly believes that Phio Pharmaceuticals is entering a decisive period that will provide multiple inflection 
opportunities  to  create  value  momentum  and  corresponding  appreciation  within  the  broader  investment 
community. We are committed to ensure this happens. 

Change in Strategic Focus to Include 2 Strategic Initiatives 

In 2018, we completed the transformation of our Company’s strategic direction, to become fully focused on 
developing  innovative  immuno-oncology  therapeutics  based  on  our  clinically  proven  gene  silencing 
technology -- self-delivering RNAi. With this change in direction we developed a corporate vision and mission, 
and established two initiatives for a successful realization of our strategy.  We also changed our name to Phio 
Pharmaceuticals from RXi Pharmaceuticals to reflect this transformation.  

OUR VISION 

To  improve  the  lives  of  cancer  patients  around  the  world  by  expanding  the  immuno-oncology 
therapeutics armamentarium with better treatment options to treat and cure cancer 

OUR MISSION 

To develop innovative cancer treatments that overcome tumor immunosuppression and weaponize 
the patient’s immune system to attack the cancer without the need for genetic modification. 

OUR STRATEGY 

To  maximize  the  value  of  our  self-delivering  RNAi  technology  in  the  immuno-oncology  space  by 
developing  a  product  pipeline  of  self-delivering  RNAi  therapeutics  in  collaboration  with  leading 
companies and academic centers.  

Our 2 strategic initiatives are: 

1. To partner with leading companies to reprogram immune cells with increased anti-tumor 
effectiveness for use in next-generation adoptive cell therapy (ACT) products 

2. To independently develop immuno-oncology therapeutics targeting the 
immunosuppressive tumor micro-environment (TME) 

Phio Pharma’s Unique Positioning in Immuno-Oncology 

Immuno-oncology is a special form of cancer therapy that improves the body’s immune system to fight cancer.  
Immune effector cells are cells that locate and attack cancer cells. In cancer patients the activity of these cells 
is often suppressed by a low inherent cell functionality, as well as significant immunobiological barriers which 

 
 
 
 
the  immune  cells  will  encounter  once  they  reach  the  tumor  micro-environment  (TME).    One  approach  to 
overcome  this  is  adoptive  cell  therapy  (ACT).  ACT  entails  the  infusion  of  immune  cells  with  antitumor 
properties.  

Currently, ACT therapies for the treatment of solid tumors face several hurdles. Multiple inhibitory mechanisms 
restrain immune cells used in ACT from effectively eradicating tumors. These inhibitory factors include immune 
checkpoints, reduced cell fitness and reduced cell persistence. Several companies use genetic engineering 
techniques (such as CRISPR) in an attempt to overcome these hurdles and in order to optimize cells used in 
ACT.    Genetic  engineering  comes  with  specific  disadvantages:  it  is  costly  and  complex.  In  addition,  these 
genetic  modifications  are  permanent  and  may  result  in  significant  safety  concerns,  raising  significant 
regulatory hurdles.  

The value proposition of Phio’s technology in immuno-oncology lies in unlocking the full potential of immune 
effector  cells  by  increasing  their  functionality  without  the  cost,  complexity  and  safety/regulatory  concerns 
associated  with  other  technologies,  such  as  genetic  engineering.  Specifically,  Phio’s  proprietary,  self-
delivering RNAi technology enables easy, precise, rapid and selective reprograming of cells, without the need 
for genetic engineering, resulting in improved cell-based immuno-therapy. Our technology can be used in 2 
ways: (1) we can directly increase the functionality of immune effector cells used in ACT, and (2) we can reduce 
the immunosuppressive nature of the TME, and directly reprogram immune cells within the TME. 

With our technology, reprograming of immune effector cells used in ACT can easily be achieved during normal 
ex vivo manufacturing of the cells, prior to patient administration. Using our therapeutics directly towards the 
TME can be done by local application of our products at the tumor site.  Both approaches are expected to 
have  utility  as  monotherapies,  as  well  as  have  a  synergistic  application  with  current  and  future 
immunotherapies.  

Our self-delivering RNAi technology also has several benefits compared to other RNAi players: we can rapidly 
and efficiently transfect target cells ex vivo, and/or directly within tumors in vivo without the need for a device 
or  specialized  formulation.  Accordingly,  Phio’s  proprietary  technology  is  designed  to  be  easier,  faster  and 
more  cost  effective.  Our  technology  has  demonstrated  to  be  compatible  with  all  forms  of  adoptive  cell 
therapies including autologous,  allogeneic and engineered cell therapies.  More  importantly,  because of its 
self-delivering  features,  local  administration  of  our  self-delivering  RNAi  results  in  extensive  local  tissue 
distribution and cellular uptake. Indeed, local administration of our proprietary self-delivering RNAi therapies 
has previously been clinically validated in various other indications.  

This  explains  why  we  have  expanded  our  strategic  focus  to  include  an  initiative  to  develop  therapeutics 
targeting the immunosuppressive tumor micro-environment (TME), in addition to our ACT program. To state it 
otherwise: since ACT can be further improved by reducing the immunosuppressive nature of the TME, we are 
developing compounds to be used to directly reprogram immune cells within the TME. The synergistic clinical 
application  of  Phio  Pharmaceuticals’  weaponized  ACT  cells  and  TME  reprogramming  has  the  potential  to 
further enhance the anti-tumor effect driven by our immunotherapies. 

2019 Focus on Advancing our Pipeline: 2 Strategic Programs with Multiple Targets 

Our current pipeline programs are based on clinically validated targets. Our lead program candidate PH-762 
(f.k.a. RXI-762) is designed to elicit PD-1 checkpoint blockade by silencing PD-1 receptor expression in T cells. 
Internal data, and data generated by several of our collaborators, show that silencing PD-1 in T cells with PH-
762 results in enhanced T cell activation and tumor cytotoxicity. Based on these exciting results, we are now 
developing PH-762 based products in both of our strategic initiatives: one pipeline product based on PH-762 
for use in ACT (based on tumor-extracted T cells) and another pipeline product based on PH-762 for direct 
TME administration. We are working aggressively to move these two product candidates into the clinic as soon 

 
 
 
as  possible.  Our  previous  predictions  on  time  needed  for  clinical  translation  of  PH-762  were  somewhat 
overoptimistic, largely because of our learning curve in immuno-oncology. To increase our R&D capabilities, 
we entered into several collaborations (see more below) allowing us to start multiple clinical studies with PH-
762 in 2020, whereas previously we were projecting only one.  

Our next pipeline product is PH-804. PH-804 can silence the expression of the immune exhaustion target TIGIT 
in  natural  killer  (NK)  cells  and  T  cells.  Overcoming  cell  exhaustion  results  in  these  immune  effector  cells 
becoming “weaponized”. Natural Killer (NK) cells are an attractive candidate for use in ACT because they are 
the body’s first line of defense against cancer cells. Unlike T cells, they are not required to be matched to a 
specific patient and therefore make an “off-the-shelf” NK-based product more feasible. In preclinical studies, 
reduction of TIGIT protein by PH-804 led to increased cytotoxic capacity of NK cells. This exciting data became 
a catalyst in expanding our ACT collaborations with certain academic and corporate institutions. Our aim is to 
advance PH-804 into the clinic in the second half of 2020. 

Meanwhile we are working to validate and prioritize additional pipeline programs to develop into ACT and TME 
therapies.  More  specifically,  we  focus  on  compounds  that  can  positively  impact  immune  cell  activity  by 
targeting cell metabolism and cell differentiation. We anticipate that we will be able to move one or more of 
these candidates into formal drug development phase in the near future. 

Technology Validated by Collaborations 

We are extremely fortunate to work with leading companies and academic institutions in the immuno-oncology 
space.  We  previously  announced  collaborations  with  Medigene,  CCIT  and  Gustave  Roussy.  In  the  last  18 
months we established additional research collaborations with Iovance Biotherapeutics, Karolinska Institutet 
and Glycostem Therapeutics. Iovance Biotherapeutics is the leading company developing novel ACT cancer 
immunotherapies based on a patient’s own T cells. Data generated in collaboration with Iovance shows that 
our  therapeutic  compounds,  such  as  PH-762,  can  improve  the  activation  and  cytotoxicity  of  Iovance's  cell 
therapy and we are now working to support the clinical translation of these findings.  

Our collaboration with the prestigious Karolinska Institutet in Stockholm, Sweden focuses on self-delivering 
RNAi  compounds  impacting  T  cell  and  NK  cell  differentiation  and  the  immune  cell  tumor-induced  stress 
response. The data generated in collaboration with the Karolinska team allow us to expand our pipeline beyond 
checkpoint targets.  

More recently, we announced our collaboration with Glycostem Therapeutics BV. Glycostem is a clinical-stage 
biotech company focused on developing off-the shelf cellular immunotherapy using NK cells to treat several 
types  of  cancer.  Under  this  collaboration,  we  aim  to  integrate  our  self-delivering  RNAi  technology  into 
Glycostem's processes to produce enhanced NK cells, with the ultimate goal of further improving Glycostem's 
cellular immunotherapies.  

Other Corporate Developments 

Organization 

Advancement of our R&D goals has been accelerated by the addition of Dr. John A. Barrett as our new Chief 
Development Officer. John comes to us most recently from Ziopharm Oncology, Inc., where he functioned as 
Vice President of R&D and Translational Medicine. He has amassed more than 25 years of R&D experience 
and  a  demonstrated  track  record  and  expertise  in  developing  cell-based  immuno-oncology  therapies.  By 
hiring John, and through other organizational enhancements, we have created the bandwidth to expand our 
R&D programs and to generate pertinent and timely non-clinical data required for regulatory filings to advance 
our programs. 

 
 
 
 
Cash Flow 

In 2018, we improved our cash position through a registered direct offering in April and an underwritten public 
offering  in  October  and  raising  approximately  $17.4  million.    In  the  meantime,  we  lowered  our  operational 
expenses to about $2 million per quarter after the completion of our RXi legacy activities. The proceeds from 
our  capital  raise  are  intended  to  fund  the  start  of  clinical  studies  for  our  lead  immuno-oncology  pipeline 
programs in 2020. We estimate that our current cash runway is sufficient to fund these efforts until Q3 2020, 
without an additional capital raise or cash inflows. Obviously, we continue to be opportunistic in seeking the 
best options to finance the Company moving forward.  

Meanwhile we continue to seek potential interested parties with whom to divest our legacy RXi assets since 
these  are no  longer part  of  our strategic focus. This has been  a challenge, however,  despite these  assets 
having compelling safety and efficacy data. Changes in the market landscape have reduced the number of 
viable players and potential market value for the assets. While we continue to explore options for these specific 
assets, we are also assessing the out-license of our core technology for therapeutic areas other than immuno-
oncology as a potential source of additional non-dilutive cash. 

Moving Forward 

While  we  made  significant  progress  throughout  2018  and  in  the  first  half  of  2019  in  transforming  Phio’s 
direction, there still remains the challenge of aligning our accomplishments and future opportunities with the 
Company’s valuation in the market. We are working diligently to realize future value inflection points, centered 
on  entering  the  clinic  with  several  pipeline  products  in  2020.    We  are  also  striving  to  improve  our 
communication to the investment community to ensure our valuation more properly reflects our achievements 
and our future value creation potential. We want to be sure we effectively communicate our new focus on the 
value  that  our  gene  silencing  technology  can  bring  to  the  exciting  immuno-oncology  space.  Whereas  the 
investment  community  understands  the  value  of  ACT,  checkpoint  inhibition  and  genetic  engineering 
technology, we want to highlight how our platform technology is ideally suited for ACT and TME applications 
relative  to  the complications of genetic engineering and other RNAi  players. In  addition,  we are  working to 
expand our relationships with clinicians, regulatory authorities and other entities that can support the clinical 
translation of our immunotherapy pipeline. 

Shareholder Value 

We submitted several proposals for voting at our upcoming 2019 Annual Meeting of Stockholders, which we 
believe serve the best interest of all Phio stakeholders. This includes a proposal for a reverse stock split in 
order to satisfy the $1.00 per share minimum bid price requirement for continued listing on the Nasdaq Capital 
Market. We have until November 11, 2019 to regain compliance by maintaining a closing bid price of at least 
$1.00 per share for a minimum of 10 consecutive business days.  Though we expect to have several positive 
Company  updates  between  now  and  this  date,  this  alone  may  not  be  sufficient  to  achieve  the  bid  price 
requirement. Accordingly, we believe a reverse split and higher stock price may encourage greater interest 
from institutional investors, business development partners and the broader investing public. We also feel it 
may help us attract and retain employees and other service providers, help us raise additional capital on more 
favorable terms, and possibly promote greater liquidity for our stockholders. We appreciate your consideration 
of the proxy proposals. We kindly ask that you vote in favor of all proposals. 

In  conclusion,  our  team  is  capable,  experienced  and  committed  to  the  diligent  execution  of  our  immuno-
oncology strategy. Our pipeline has broad application and backed by  various families of strong intellectual 
property. Our collaborations with industry and academia further reflect the perceived value creation within the 
therapeutic space which Phio can generate to enhance shareholder value. Therefore, we believe that the next 

 
 
 
12-18  months  will  be  transformational  for  Phio  and  that  the  progress  will  create  a  significant  investment 
opportunity for our shareholders and for new investors. 

On behalf of Phio Pharmaceuticals employees, thank you for your investment to date, your continued support, 
your encouragement, advice and comments.  With your backing we will deliver on our corporate vision and 
change the lives of cancer patients with better treatment options to treat and cure cancer. 

Very truly yours,

PART I

ITEM 1.

BUSINESS 

Overview

Phio Pharmaceuticals Corp. is a biotechnology company developing the next generation of immuno-oncology therapeutics based on our 

self-delivering RNAi (“sd-rxRNA®”) therapeutic platform. The Company’s efforts are focused on developing sd-rxRNA therapeutic compounds to 
be used in the context of adoptive cell transfer by targeting checkpoints or other gene targets, or to be used in immunotherapy following intra-
tumoral injections. We aim to maximize the power of our sd-rxRNA therapeutic compounds by weaponizing therapeutic immune effector cells to 
attack cancer, and to make tumors more susceptible to such attacks, and ultimately provide patients battling cancers with a powerful new treatment 
option that goes beyond current treatment modalities.

In January 2017, the Company entered into a Stock Purchase Agreement pursuant to which it acquired all of the issued and outstanding 
shares of capital stock of MirImmune Inc. (“MirImmune”) for an aggregate of 275,036 shares of common stock of the Company and 1,118,224 
shares of the Company’s Series C Convertible Preferred Stock. With the approval of the Company’s stockholders at the 2017 Annual Meeting of 
Stockholders, every ten shares of the Series C Convertible Preferred Stock issued and outstanding were automatically converted into one share of 
common stock.

Prior to the Company’s acquisition of MirImmune, our principal activities consisted of the preclinical and clinical development of the 
Company’s sd-rxRNA compounds and topical immunotherapy agent in the areas of dermatology and ophthalmology. In January 2018, after a 
thorough review of its business operations, development programs and financial resources, the Company made a strategic decision to focus its 
efforts solely on immuno-oncology to accelerate growth and support a potential return on investment for its stockholders. In connection with this 
decision, the Company completed all open clinical trials in dermatology and ophthalmology with RXI-109, our first sd-rxRNA clinical candidate, 
and Samcyprone®, and reported out on the results of those clinical studies in 2018. The Company intends to seek a partner and/or out-licensee for its 
dermatology program and its ophthalmology program to continue with their development. The Company’s current business strategy solely focuses 
on the development of immuno-oncology therapeutics utilizing our proprietary sd-rxRNA technology.

On November 19, 2018, the Company changed its name from RXi Pharmaceuticals Corporation to Phio Pharmaceuticals Corp., which 

reflects the Company’s transition from a platform company to one that is fully committed to develop groundbreaking immuno-oncology 
therapeutics. 

Our development efforts are based on our broadly patented sd-rxRNA technology platform. Our sd-rxRNA compounds do not require a 
delivery vehicle to penetrate into tissues and cells and are designed to “silence,” or down-regulate, the expression of a specific gene that may be 
over-expressed in a disease condition. We believe that our sd-rxRNA platform uniquely positions the Company in the field of immuno-oncology 
because of this and for the following reasons:

 Our sd-rxRNA compounds do not require facilitated delivery (mechanical or formulation);



Can target multiple genes (i.e. multiple immunosuppression pathways) in a single therapeutic entity;

 Demonstrate efficient uptake of sd-rxRNA to immune cells;







Silencing by sd-rxRNA has been shown to have a sustained, or long-term, effect in vivo;

Favorable clinical safety profile of sd-rxRNA with local administration; and

Can be readily manufactured under current good manufacturing practices.

On January 3, 2018, the Board of Directors of the Company approved a 1-for-10 reverse stock split of the Company’s outstanding common 

stock, which was effected on January 8, 2018. All share and per share amounts have been retroactively adjusted for all periods presented to give 
effect to the reverse stock split, including reclassifying an amount equal to the reduction in par value to additional paid-in capital in the financial 
statements.

Our Development Pipeline

We currently have a pipeline of discovery and preclinical programs in three focus areas in which we are aligning our internal research and 
development efforts with extramural collaborations. The table below sets forth the Company’s stage of development for product candidates in each 
of our three R&D focus areas:

Checkpoint Inhibition in Adoptive Cell Transfer 

The Company has developed sd-rxRNA targeting PD-1, TIGIT and other undisclosed checkpoints in adoptive cell transfer (“ACT”) for the 

treatment of solid tumors. RXI-762 and RXI-804, sd-rxRNA compounds that are designed to suppress the expression of immune checkpoint 
proteins PD-1 and TIGIT, respectively, which, when used in ACT, are expected to result in an improved efficacy to the targeted tumors. We expect 
to enter clinical development with RXI-762, our most advanced program, as part of an ACT therapy for solid tumors in melanoma by the end of 
2019.

Our strategy includes advancing our sd-rxRNA compounds towards clinical development, both independently and with extramural 
collaborations. We plan to focus our internal resources on therapeutic areas where research and development is appropriate for the size and financial 
resources of the Company and to secure partners in therapeutic areas with the requisite expertise and resources to advance our product and research 
candidates through clinical development. We believe that this approach to our strategy will allow us to build upon these current collaborations to 
add additional partnerships to our immuno-oncology pipeline, support the Company with a shorter path to the clinic by allowing us to utilize and 
build upon already established protocols of our partners and provide us with the opportunity to expand our immuno-oncology programs and pipeline 
in multiple areas. We have established a number of collaborations with cancer research institutions and companies in this therapeutic area.

The Center for Cancer Immune Therapy (“CCIT”) at Herlev Hospital is a leading European cancer center for use of tumor-infiltrating 

lymphocytes (“TILs”) for ACT. CCIT has carried out numerous clinical trials based on a direct translation of the discoveries from the laboratory. 
Our collaboration with CCIT is evaluating the potential of our sd-rxRNA technology platform to enhance the function of TILs for use in the 
treatment for a number of cancer types, including melanoma and ovarian cancer. To date, CCIT has evaluated sd-rxRNA compounds targeting 
immune checkpoints in preclinical screening models of matched TIL/tumor cell pairs from melanoma and cancer patients. Results have shown a 
marked PD-1 reduction on the surface of TILs in a pilot rapid expansion protocol.

Iovance Biotherapeutics, Inc. is a biotechnology company focused on the development and commercialization of autologous cellular 

immunotherapies optimizing personalized, tumor-directed TILs. Our research collaboration with Iovance will evaluate the potential synergies with 
our novel sd-rxRNA therapeutic compounds and Iovance’s autologous cell therapy based on TILs for the use in the treatment of cancer. Data from 
this collaboration has shown that a sd-rxRNA mediated knock-down of PD-1 was associated with phenotypic changes indicative of TIL activation. 
Our next steps with Iovance include further evaluation of the impact of sd-rxRNA mediated gene silencing on TIL tumor reactivity and 
implementation of optimized silencing protocols and scale-up thereof.

Cell Maturation and Metabolism in Adoptive Cell Transfer

We use our sd-rxRNA in T-cells and other immune cell types, such as natural killer (“NK”) cells and dendritic cells, for targets other than 
immune checkpoints in order to weaponize and improve cell persistence and cell viability in the immunosuppressive tumor micro-environment. We 
believe this shows the broad applicability of our platform technology and that our potential impact in immuno-oncology is not limited to 
checkpoints and TILs.

We have shown that sd-rxRNAs are rapidly and efficiently taken up by immune effector cells without the use of transfection reagents. 

Using sd-rxRNA compounds against checkpoint inhibitors, we can suppress their expression levels up to 95% in immune cells, including T-cells 
and NK cells. Furthermore, we have demonstrated potent silencing activity as well as a phenotypic effect (enhanced degranulation activity) of NK 
cells treated with sd-rxRNA compounds targeting checkpoints. By treating NK cells ex-vivo, prior to ACT with sd-rxRNA reducing the expression 
of proteins such as Cbl-b and TIGIT, the anti-tumor response of these cells can be improved. Ongoing work expands these findings to include 
compounds for more specific NK targets, including NK specific inhibitory receptors, which could be used alone or in combination.

Through our collaboration with Medigene AG, a German biotechnology company developing highly innovative, complementary treatment 

platforms to target various types and stages of cancer, we are exploring the potential synergies of our sd-rxRNA technology in combination with 
Medigene’s recombinant TCRs to develop modified T-cells with enhanced efficacy and/or safety with the ultimate goal to further improve 
Medigene’s T-cell therapies for the treatment of cancer patients. In the studies completed, Medigene observed the reduction of PD-1 surface levels 
in T-cells transduced with TCRs and treated with our sd-rxRNA compound, RXI-762. While these studies utilized the Company’s PD-1 targeting 
sd-rxRNA for proof of concept, there is also the potential to expand the collaboration to additional targets and the two complementing technologies 
could lead to synergistic effects that might further sharpen and improve the therapeutic effects of Medigene’s receptor modified T-cells.

Direct Tumor and Tumor Micro-Environment 

Our third focus area includes the use of our sd-rxRNA directly towards tumor and/or tumor micro-environment (“TME”) targets. 
Impacting the tumor cells and/or TME through a direct use of sd-rxRNA, such as via intra-tumoral injection, could potentially become an important 
form of adjuvant therapy. We believe that this will also show that our contributions with our sd-rxRNA compounds in immuno-oncology are not 
limited to use with another company’s cell platform. Additionally, the Company has shown that its sd-rxRNA compounds are safe and well-
tolerated via intradermal injections and injections in the eye through its completed clinical trials with RXI-109 in dermatology and ophthalmology.

Our collaborative research agreement with Gustave Roussy, a leading comprehensive cancer center in France, concentrates on determining 

the feasibility of our sd-rxRNA platform to target the TME via intra-tumoral injection. The goal of our recent in vivo study with Gustave Roussy 
was to demonstrate sd-rxRNA compound delivery via intra-tumoral injection and demonstrate activity (silencing of gene expression) of sd-rxRNA 
compounds. Results from this study showed an 80—85% reduction of the target gene expression in a mouse model of melanoma via intra-tumoral 
injection.

Our sd-rxRNA Platform 

Diseases are often related to the wrong protein being made, excessive amounts of a specific protein being made, or the correct protein 

being made but at the wrong location or time. Overall, RNA is involved in the synthesis, regulation and processing of proteins. RNA interference 
(“RNAi’) is a biological process in which RNA molecules inhibit gene expression or translation into proteins by preventing certain RNA from being 
read. RNAi offers a novel approach to the drug development process because RNAi compounds can potentially be designed to target any one of the 
thousands of human genes, many of which are “undruggable” by other modalities. Supported by numerous gene-silencing reports and our own 
research, we believe that this sequence information can be used to design RNAi compounds to interfere with the expression of almost any specific 
gene.

The first design of RNAi compounds to be pursued for the development of human therapeutics were short, double-stranded RNAs that 

included limited modifications, known as small-interfering RNA (“siRNA”). Since the initial discovery of RNAi, drug delivery has been the 
primary challenge in developing RNAi-based therapeutics. One conventional solution to the delivery problem involves encapsulation of siRNA into 
a lipid-based particle, such as a liposome, to improve circulation time and cellular uptake. We have developed an alternative approach where 
delivery and drug-like properties are built directly into the RNAi compound itself. These novel compounds are termed self-delivering RNAi 
compounds, or sd-rxRNA.

sd-rxRNAs are hybrid oligonucleotide compounds that the Company believes combines the beneficial properties of both conventional 

RNAi and antisense technologies. Traditional, single-stranded antisense compounds have favorable tissue distribution and cellular uptake properties. 
However, they do not have the intracellular potency that is a hallmark of double-stranded RNAi compounds. Conversely, the duplex structure and 
hydrophilic character of traditional RNAi compounds results in poor tissue distribution and cellular uptake. In an attempt to combine the best 
properties of both technologies, sd-rxRNA have a single-stranded phosphorothioate region, a short duplex region, and contain a variety of nuclease-
stabilizing and lipophilic chemical modifications. The combination of these features allows sd-rxRNA to achieve efficient spontaneous cellular 
uptake and potent, long-lasting intracellular activity.

We believe that our next generation sd-rxRNA compounds offer significant advantages over siRNAs used by other companies developing 

RNAi therapeutics, which are highlighted by the following characteristics:

 Efficient cellular uptake in the absence of a delivery vehicle;

 Potent RNAi activity;

 More resistant to nuclease degradation than unmodified oligonucleotides;

 Able to suppress long non-coding RNAs, both in cytoplasm and the nucleus;

 Readily manufactured;

 Potentially more specific for the target gene; and

 Reduced immune side effects compared to classic siRNA.

The route by which our sd-rxRNA compounds are brought into contact with the body depends on the intended organ or tissue to be treated. 
Delivery routes can be simplified into two major categories: (1) local, or when a drug is delivered directly to the tissue of interest, and (2) systemic, 
when a drug accesses the tissue of interest through the circulatory system. The key to therapeutic success with RNAi lies in delivering intact RNAi 
compounds to the target tissue and the interior of the target cells. To accomplish this, our chemically synthesized sd-rxRNA compounds are 
optimized for stability and efficacy and have unique properties that improve tissue and cell uptake.

Our Adoptive Cell Transfer Approach

The self-delivering nature of our compounds makes sd-rxRNA ideally suited for use with ACT treatments and direct therapeutic use. In 
ACT, immune cells are isolated from specific patients or retrieved from allogeneic immune cell banks. The immune cells are then expanded and 
modified before being returned and used to treat the same patient. We believe our sd-rxRNA compounds are ideally suited to be used in 
combination with ACT, in order to make these immune cells more effective. 

ACT includes a number of different types of immunotherapy treatments. These treatments all use immune cells, such as T-cells, that are 

grown in a lab to large numbers, followed by administering them to the body to fight the cancer cells. Sometimes, immune cells that naturally 
recognize a tumor are used, while other times immune cells are modified or “engineered” to make them recognize and kill the cancer cells. There 
are several types of ACT, including: a.) non-engineered cell therapy in which immune cells are grown from the patient’s tumor or blood, such as 
TILS, or from donor blood or tissue such as NK cells, and b.) engineered immune cells in which these cells are genetically modified to recognize 
specific tumor proteins and to remain in an activated state (such as CAR T-cells and T-cell Receptors, or TCRs, and CAR NK cells).

Our approach to immunotherapy builds on well-established methodologies of ACT and involves the treatment of immune cells with our sd-

rxRNA compounds during the expansion and modification phase. As shown below, immune cells are isolated from specific patients or retrieved 
from allogeneic immune cell banks and then expanded and sometimes processed to express tumor-binding receptors. Because our sd-rxRNA 
compounds do not require a delivery vehicle to penetrate into the cells, we are able to enhance these cells (for example by inhibiting the expression 
of immune checkpoint genes) by merely adding our sd-rxRNA compounds during the expansion process and without the need for genetic 
engineering. After enhancing these cells ex vivo, they are returned to the patient for treatment.

Our method introduces an important step in the ex vivo processing of immune cells. This step uses our sd-rxRNA technology to reduce or 

eliminate the expression of genes that make the immune cells less effective. For example, with our sd-rxRNA compounds, we can reduce the 
expression of immunosuppressive receptors or proteins by the therapeutic immune cells, potentially enabling them to overcome tumor resistance 
mechanisms and thus improving their ability to destroy the tumor cells. In various types of immune cells tested to date, sd-rxRNA treatment results 
in potent silencing while maintaining close to 100% transfection efficiency and nearly full cell viability.

6

We believe that a major advantage to our approach is that pre-treatment with our targeted compounds allows for multiple immune 
checkpoints to be attenuated within the same therapeutic cell, an improvement which could dramatically increase their tumor cell killing capability. 
In addition, these therapeutic immune cells may lack some known side effects associated with systemic checkpoint inhibitor therapies, while 
potentially improving efficacy over current immunotherapy approaches.

Additionally, one of the main issues with ACT is that the cells are very susceptible to the cancer signals that turn down the immune 

response and continuous activation of these cells causes them to become exhausted. These factors, among others, may reduce their efficacy and 
lifespan. A technology that can reprogram the immune cells using ACT, such as sd-rxRNA, is of key interest now in the immuno-oncology world.

Our Dermatology and Ophthalmology Programs 

The Company intends to seek a partner and/or out-licensee for both its dermatology and ophthalmology programs, which includes RXI-109 

and Samcyprone, to continue their development.

Dermatology – Hypertrophic Scarring

The Company’s first RNAi clinical product candidate, RXI-109, is a sd-rxRNA that commenced human clinical trials in 2012. RXI-109 is 

designed to reduce the expression of connective tissue growth factor (“CTGF”), a critical regulator of several biological pathways involved in 
fibrosis, including scar formation in the skin and eye. Two Phase 1 clinical trials completed by the Company demonstrated the safety and tolerability 
of RXI-109 in ascending single and multi-doses and also provided the first evidence of clinical activity in a surgical setting. The Phase 1 clinical 
trials provided the desired profile to enable the initiation of a Phase 2a clinical trial. Positive results from Study 1402, our Phase 2a clinical trial with 
RXI-109 in hypertrophic scars, were reported in December 2017. The study met the primary effectiveness objective as shown by a statistically 
significant improved visual appearance of revised scars after scar revision surgery and treatment with RXI-109 versus control, as assessed by the 
investigator. The full study results showed that the product was safe and well tolerated for all dosage groups. Exploratory endpoint analysis 
furthermore showed that the cosmetic outcomes of RXI-109 treated scars were highly preferred over the untreated revised scars, by both 
investigators and patients. The study results show furthermore that RXI-109 was safe and well tolerated.

Dermatology – Warts

Samcyprone, the Company’s second clinical candidate, is a proprietary topical formulation of the small molecule diphenylcyclopropenone 

(“DPCP”), an immunomodulator that works by initiating a T-cell response.

In May 2018, the Company announced results from its Phase 2 clinical trial with Samcyprone in cutaneous warts. The primary 

effectiveness objectives were met as shown by high levels of immunotherapeutic response and therapeutic response. The immunotherapeutic 
response rate – a prerequisite for therapeutic response – was 97.7% across all 88 subjects enrolled in the study. From a therapeutic response 
viewpoint, with once weekly dosing for up to 10 weeks, more than 70% of all warts showed a positive wart response rate, i.e. reduction of wart size 
of more than 50%. Complete wart clearance throughout the study was 54% for all warts, and up to 71.4% for certain wart types (non-plantar warts). 
The study results show furthermore that Samcyprone was safe and well tolerated.

Dermatology – Uneven Skin Tone and Pigmentation

Cosmetics are compounds that affect the appearance of the skin and make no preventative or therapeutic claims. These compounds may be 
developed more rapidly than therapeutics, therefore the path to market may be much shorter and less expensive. RXI-231, an sd-rxRNA compound 
targeting tyrosinase (“TYR”), was selected by the Company for cosmetic development. TYR is a key enzyme in the synthesis of melanin. Melanin 
is produced by melanocytes and is the pigment that gives human skin, hair and eyes their color. The inhibition of TYR can play a key role in the 
management of skin conditions including cutaneous hyperpigmentation disorders such as lentigines (freckles, age spots and liver spots) and possibly 
melanoma.

7

Three studies were performed under the consumer testing program with RXI-231. The first two studies in volunteers determined that the 

RXI-231 gel formulation did not cause irritation and sensitization when applied to the skin. The third study investigated the potential of RXI-231 to 
impact a skin melanin content (pigmentation) increase induced by UV exposure in a study design similar to one well documented in peer-reviewed 
journal articles and used by various cosmetic companies. Specific spectroscopic results showed that application of RXI-231 containing gel, as 
compared to a vehicle gel, can reduce a change of skin tone triggered by UV. These results not only validate our preclinical data about the effect of 
RXI-231 on skin pigmentation, but also provide important information on the capabilities of our proprietary topical formulation for the use of our 
sd-rxRNA based cosmetic ingredients in the consumer care space.

Ophthalmology – Retinal Scarring

As in dermal scarring, RXI-109 can also be used to target CTGF in the eye, where CTGF is known to be involved in retinal scarring. 

Building on the work in our dermal clinical program, the Company initiated a Phase 1/2 clinical trial to evaluate the safety and clinical activity of 
RXI-109 in reducing the progression of retinal scarring. In August 2018, the Company announced positive results from our Phase 1/2 clinical trial to 
evaluate the safety and clinical activity of RXI-109 in reducing the progression of retinal scarring in subjects with wet age-related macular 
degeneration with evidence of subretinal fibrosis. Each subject in the study received four doses of RXI-109 by intraocular injection at one-month 
intervals for a total dosing period of three months. The primary objective was met as shown by the absence of dose-limiting and serious toxicities, 
and only mild to moderate procedure related adverse events. None of the adverse events were drug related. In addition, comprehensive ocular 
examinations showed no indications of inflammation nor any other tolerability issues related to the treatment. The secondary objective of the study 
was also met with improved or stable disease in the study eyes of several subjects.

Intellectual Property 

We protect our proprietary information by means of United States and foreign patents, trademarks and copyrights. In addition, we rely 

upon trade secret protection and contractual arrangements to protect certain of our proprietary information and products. We have pending patent 
applications that relate to potential drug targets, compounds we are developing to modulate those targets, methods of making or using those 
compounds and proprietary elements of our drug discovery platform.

Much of our technology and many of our processes depend upon the knowledge, experience and skills of key scientific and technical 

personnel. To protect our rights to our proprietary know-how and technology, we require all employees, as well as our consultants and advisors 
when feasible, to enter into confidentiality agreements that require disclosure and assignment to us of ideas, developments, discoveries and 
inventions made by these employees, consultants and advisors in the course of their service to us, and we vigorously defend that position with 
partners, as well as with employees who leave the Company.

We have also obtained rights to various patents and patent applications under licenses with third parties, which require us to pay royalties, 
milestone payments, or both. The degree of patent protection for biotechnology products and processes, including ours, remains uncertain, both in 
the United States and in other important markets, because the scope of protection depends on decisions of patent offices, courts and lawmakers in 
these countries. There is no certainty that our existing patents or others, if obtained, will afford us substantial protection or commercial benefit. 
Similarly, there is no assurance that our pending patent applications or patent applications licensed from third parties will ultimately be granted as 
patents or that those patents that have been issued or are issued in the future will stand if they are challenged in court. We assess our license 
agreements on an ongoing basis and may from time to time terminate licenses to technology that we do not intend to employ in our technology 
platforms, or in our product discovery or development activities.

checkpoint, cellular differentiation and metabolism targets for ex vivo cell-based cancer immunotherapies, as well as uses of our sd-rxRNAs 
targeting CTGF for the treatment of fibrotic disorders (including RXI-109 for the treatment of dermal and ocular fibrosis). These patents are 
scheduled to expire between 2029 and 2038. Furthermore, there are 75 patent applications, encompassing what we believe to be important new 
RNAi compounds and their use as therapeutics and/or cosmetics, chemical modifications of RNAi compounds that improve the compounds’ 
suitability for therapeutic uses (including delivery) and compounds directed to specific targets (i.e., that address specific disease states).

The patents and any patents that may issue from these pending patent applications will, if issued, be set to expire between 2022 and 2038, 

not including any patent term extensions that may be afforded under the Federal Food, Drug, and Cosmetic Act (“FFDCA”) (and the equivalent 
provisions in foreign jurisdictions) for any delays incurred during the regulatory approval process relating to human drug products (or processes for 
making or using human drug products).

The Samcyprone portfolio includes 1 issued patent and 5 patent applications. The patent and patent applications cover both the 
compositions and methods of use of Samcyprone for the treatment of warts, human papilloma virus (HPV) skin infections, skin cancer (including 
melanoma) and immunocompromised patients. The patent and any patents that may issue from the pending applications will be set to expire 
between 2019 and 2036, not including any patent term extensions that may be afforded under the FFDCA (and the equivalent provisions in foreign 
jurisdictions) for any delays incurred during the regulatory approval process relating to human drug products (or processed for making or using 
human drug products).

License Agreements 

We have secured exclusive and non-exclusive rights to develop therapeutics by licensing key RNAi technologies, Samcyprone and patent 

rights from third parties. These rights relate to chemistry and configuration of compounds, delivery technologies of compounds to cells and 
therapeutic targets. As we continue to develop our own proprietary compounds, we continue to evaluate both our in-licensed portfolio as well as the 
field for new technologies that could be in-licensed to further enhance our intellectual property portfolio and unique position in the RNAi and 
immuno-oncology space.

Advirna LLC. In September 2011, we entered into an agreement with Advirna, LLC (“Advirna”) pursuant to which Advirna assigned to us 
its existing patent and technology rights related to sd-rxRNA technology in exchange for our agreement to issue to Advirna common stock equal to 
5% of the Company’s fully-diluted shares, pay an annual maintenance fee of $100,000 and pay a one-time milestone payment of $350,000 upon the 
issuance of the first patent with valid claims covering the assigned technology. The common shares of the Company were issued to Advirna in 2012 
upon the completion of the spin-out from our former parent company and the one-time milestone payment was paid in 2014. Additionally, we will 
be required to pay a 1% royalty to Advirna on any license revenue received by us with respect to future licensing of the assigned Advirna patent and 
technology rights. We also granted back to Advirna a license under the assigned patent and technology rights for fields of use outside human 
therapeutics and diagnostics.

9

Our rights under the Advirna agreement will expire upon the later of: (i) the expiration of the last-to-expire of the “patent rights” (as 

defined therein) or (ii) the abandonment of the last-to-be abandoned of such patents, unless earlier terminated in accordance with the provisions of 
the agreement.

We may terminate the Advirna agreement at any time upon 90 days’ written notice to Advirna, and Advirna may terminate the agreement 

upon 90 days’ prior written notice in the event that we cease using commercially reasonable efforts to research, develop, license or otherwise 
commercialize the patent rights or “royalty-bearing products” (as defined therein), provided that we may refute such claim within such 90-day 
period by showing budgeted expenditures for the research, development, licensing or other commercialization consistent with other technologies of 
similar stage of development and commercial potential as the patent rights or royalty-bearing products. Further, either party at any time may provide 
to the other party written notice of a material breach of the agreement. If the other party fails to cure the identified breach within 90 days after the 
date of the notice, the aggrieved party may terminate the agreement by written notice to the party in breach.

Hapten Pharmaceuticals, LLC. In December 2014, the Company entered into an Assignment and License Agreement with Hapten 
Pharmaceuticals, LLC (“Hapten”) under which Hapten agreed to sell and assign to us certain patent rights and related assets and rights, including 
an investigational new drug application and clinical data, for Hapten’s Samcyprone products for therapeutic and prophylactic use. Under the 
Assignment and License Agreement, and upon the closing of the agreement which occurred in February 2015, Hapten received a one-time upfront 
cash payment of $100,000 and we issued to Hapten 2,000 shares of common stock of the Company. Pursuant to the Assignment and License 
Agreement, Hapten will be entitled to receive: (i) future milestone payments tied to the achievement of certain clinical and commercial objectives 
(all of which payments may be made at our option in cash or through the issuance of common stock) and (ii) escalating royalties based on product 
sales by us and any sublicensees.

We have certain customary diligence obligations under the Assignment and License Agreement requiring us to use commercially 
reasonable efforts to develop and commercialize one or more products covered by the Assignment and License Agreement, which obligations, if not 
performed, could result in rights assigned or licensed to us reverting back to Hapten.

In addition to the license agreements listed above, the Company has entered into and may enter into other license agreements that may 

benefit us as we develop our therapeutic pipelines.

Other Licensing Agreements 

OPKO Health, Inc. In March 2013, the Company entered into an Asset Purchase Agreement (the “Asset Purchase Agreement”) with 

OPKO Health, Inc. (“OPKO”), in which we acquired substantially all of its RNAi-related assets, which included patents and patent applications, 
licenses, clinical and preclinical data and other related assets. In exchange for the assets that we purchased from OPKO, we issued 16,667 shares of 
our common stock and agreed to pay, if applicable: (i) up to $50 million in development and commercialization milestones for the successful 
development and commercialization of each “Qualified Drug” (as defined therein) and (ii) royalty payments equal to: (a) a mid-single-digit 
percentage of “Net Sales” (as defined therein) with respect to each Qualified Drug sold for an ophthalmologic use during the applicable “Royalty 
Period” (as defined therein) and (b) a low-single-digit percentage of Net Sales with respect to each Qualified Drug sold for a non-ophthalmologic 
use during the applicable Royalty Period.

We have certain customary diligence obligations under the Asset Purchase Agreement requiring us to use commercially reasonable efforts 
to develop and commercialize one or more products covered by the Asset Purchase Agreement, which obligations, if not performed, could result in 
assets transferred and rights assigned or licensed to us reverting back to OPKO.

Thera Neuropharma, Inc. In May 2016, Phio granted an exclusive license to Thera Neuropharma, Inc. (“Thera”) to the Company’s novel 

and proprietary sd-rxRNA platform to develop therapeutics for neurodegenerative diseases. Under the terms of the agreement, Thera will be 
responsible for all research, development, manufacturing, regulatory and commercialization activities for the licensed products. Thera’s initial focus 
will be on sd-rxRNA compounds targeting superoxide dismutase 1 (SOD1) for use in developing innovative treatments for amyotrophic lateral 
sclerosis (ALS), commonly known as Lou Gehrig’s disease. Upon execution of the license agreement, Phio was issued shares of common stock of 
Thera and was granted a five-year warrant to purchase additional shares of common stock of Thera pursuant to the terms of the license agreement. 
The Company is eligible to receive future cash, additional equity and royalties based on the achievement of certain milestones.

Acquired In-Process Research and Development 

Assets purchased in an asset acquisition transaction are expensed as in-process research and development unless the assets acquired have 

an alternative future use. Acquired in-process research and development payments are immediately expensed and include upfront payments, as well 
as transaction fees and subsequent milestone payments. Development costs incurred after the acquisition are expensed as incurred.

The Company did not complete an asset acquisition transaction during the year ended December 31, 2018 that would require the recording 

of acquired in-process research and development expense. Total acquired in-process research and development expense for the year ended 
December 31, 2017 was $4,696,000, and related to the fair value of consideration given, which includes transaction costs, liabilities assumed and 
cancellation of notes receivable, and the deferred tax impact of the Company’s acquisition of MirImmune.

Competition

The biotechnology and pharmaceutical industries, including the immuno-oncology field, are a constantly evolving landscape with rapidly 

advancing technologies and significant competition. There are a number of competitors in the immuno-oncology field including large and small 
pharmaceutical and biotechnology companies, academic institutions, government agencies and other private and public research organizations.

A variety of cell-based autologous and allogeneic approaches are being researched and developed, including but not limited to: CAR-T

Government Regulation 

The United States and many other countries extensively regulate the preclinical and clinical testing, manufacturing, labeling, storage, 

record-keeping, advertising, promotion, export, marketing and distribution of drugs and biologic products. The U.S. Food and Drug Administration 
(“FDA”) regulates pharmaceutical and biologic products under the FFDCA, the Public Health Service Act and other federal statutes and regulations.

To obtain approval of our future product candidates from the FDA, we must, among other requirements, submit data supporting safety and 
efficacy for the intended indication as well as detailed information on the manufacture and composition of the product candidate. In most cases, this 
will require extensive laboratory tests and preclinical and clinical trials. The collection of these data, as well as the preparation of applications for 
review by the FDA involve significant time and expense. The FDA also may require post-marketing testing to monitor the safety and efficacy of 
approved products or place conditions on any approvals that could restrict the therapeutic claims and commercial applications of these products. 
Regulatory authorities may withdraw product approvals if we fail to comply with regulatory standards or if we encounter problems at any time 
following initial marketing of our products.

11

The first stage of the FDA approval process for a new biologic or drug involves completion of preclinical studies and the submission of the 

results of these studies to the FDA. These data, together with proposed clinical protocols, manufacturing information, analytical data and other 
information submitted to the FDA in an investigational new drug (“IND”) application, must become effective before human clinical trials may 
commence. Preclinical studies generally involve FDA regulated laboratory evaluation of product characteristics and animal studies to assess the 
efficacy and safety of the product candidate.

After the IND becomes effective, a company may commence human clinical trials. These are typically conducted in three sequential 
phases, but the phases may overlap. Phase 1 trials consist of testing the product candidate in a small number of patients or healthy volunteers, 
primarily for safety at one or more doses. Phase 2 trials, in addition to safety, evaluate the efficacy of the product candidate in a patient population 
somewhat larger than Phase 1 trials. Phase 3 trials typically involve additional testing for safety and clinical efficacy in an expanded population at 
multiple test sites. A company must submit to the FDA a clinical protocol, accompanied by the approval of the Institutional Review Board (“IRB”) 
at the institutions participating in the trials, prior to commencement of each clinical trial.

To obtain FDA marketing authorization, a company must submit to the FDA the results of the preclinical and clinical testing, together with, 

among other things, detailed information on the manufacture and composition of the product candidate, in the form of a new drug application 
(“NDA”), or, in the case of a biologic, a biologics license application (“BLA”).

The amount of time taken by the FDA for approval of an NDA or BLA will depend upon a number of factors, including whether the 
product candidate has received priority review, the quality of the submission and studies presented, the potential contribution that the compound will 
make in improving the treatment of the disease in question and the workload at the FDA.

The FDA may, in some cases, confer upon an investigational product the status of a fast track product. A fast track product is defined as a 
new drug or biologic intended for the treatment of a serious or life-threatening condition that demonstrates the potential to address unmet medical 
needs for this condition. The FDA can base approval of an NDA or BLA for a fast track product on an effect on a surrogate endpoint, or on another 
endpoint that is reasonably likely to predict clinical benefit. If a preliminary review of clinical data suggests that a fast track product may be 
effective, the FDA may initiate review of entire sections of a marketing application for a fast track product before the sponsor completes the 
application.

We anticipate that our products will be manufactured by our strategic partners, licensees or other third parties. Before approving an NDA 

or BLA, the FDA will inspect the facilities at which the product is manufactured and will not approve the product unless the manufacturing facilities 
are in compliance with the FDA’s cGMP, which are regulations that govern the manufacture, holding and distribution of a product. Manufacturers 
of biologics also must comply with the FDA’s general biological product standards. Our manufacturers also will be subject to regulation under the 
Occupational Safety and Health Act, the Nuclear Energy and Radiation Control Act, the Toxic Substance Control Act and the Resource 
Conservation and Recovery Act and other applicable environmental statutes. Following approval, the FDA periodically inspects drug and biologic 
manufacturing facilities to ensure continued compliance with the cGMP. Our manufacturers will have to continue to comply with those 
requirements. Failure to comply with these requirements subjects the manufacturer to possible legal or regulatory action, such as suspension of 
manufacturing or recall or seizure of product. Adverse patient experiences with the product must be reported to the FDA and could result in the 
imposition of marketing restrictions through labeling changes or market removal. Product approvals may be withdrawn if compliance with 
regulatory requirements is not maintained or if problems concerning safety or efficacy of the product occur following approval.

The labeling, advertising, promotion, marketing and distribution of a drug or biologic product also must be in compliance with FDA and 

Federal Trade Commission requirements which include, among others, standards and regulations for off-label promotion, industry sponsored 
scientific and educational activities, promotional activities involving the internet, and direct-to-consumer advertising. We also will be subject to a 
variety of federal, state and local regulations relating to the use, handling, storage and disposal of hazardous materials, including chemicals and 
radioactive and biological materials. In addition, we will be subject to various laws and regulations governing laboratory practices and the 
experimental use of animals. In each of these areas, as above, the FDA has broad regulatory and enforcement powers, including the ability to levy 
fines and civil penalties, suspend or delay issuance of product approvals, seize or recall products and deny or withdraw approvals.

12

We will also be subject to a variety of regulations governing clinical trials and sales of our products outside the United States. Whether or 

not FDA approval has been obtained, approval of a product candidate by the comparable regulatory authorities of foreign countries and regions must 
be obtained prior to the commencement of marketing the product in those countries. The approval process varies from one regulatory authority to 
another and the time may be longer or shorter than that required for FDA approval. In the European Union, Canada and Australia, regulatory 
requirements and approval processes are similar, in principle, to those in the United States.

Environmental Compliance 

Our research and development activities involve the controlled use of potentially harmful biological materials as well as hazardous 
materials, chemicals and various radioactive compounds. We are subject to federal, state and local laws and regulations governing the use, storage, 
handling and disposal of these materials and specific waste products. We are also subject to numerous environmental, health and workplace safety 
laws and regulations, including those governing laboratory procedures, exposure to blood-borne pathogens and the handling of bio-hazardous 
materials. The cost of compliance with these laws and regulations could be significant and may adversely affect capital expenditures to the extent 
we are required to procure expensive capital equipment to meet regulatory requirements.

Employees 

As of March 22, 2019, we had nine full-time employees. None of our employees are represented by a labor union or covered by a collective 

bargaining agreement nor have we experienced any work stoppages.

ITEM 1A. RISK FACTORS

Risks Relating to Our Business and Industry 

The approach we are taking to discover and develop novel therapeutics using RNAi may never lead to marketable products. 

Our research and development efforts and our future success is based on our sd-rxRNA technology platform. The use of RNA interference 

is a relatively new scientific discovery and the first regulatory approval of an RNAi therapeutic recently occurred in August 2018. The scientific 
evidence to support the feasibility of developing drugs based on these discoveries is limited. We may spend large amounts of money trying to 
develop our sd-rxRNA technology and may never succeed in doing so. In addition, any compounds that we develop may not demonstrate in subjects 
the chemical and pharmacological properties ascribed to them in laboratory studies, and they may interact with human biological systems in 
unforeseen, ineffective or even harmful ways. If we are not successful in developing a product candidate using our sd-rxRNA technology, we may 
not be able to identify and successfully implement an alternative product development strategy.

13

We have limited experience in operating our current business in the area of immuno-oncology. 

We have only a limited operating history with our current business strategy on which a decision to invest in our Company can be based. 

Prior to the Company’s acquisition of MirImmune Inc. in January 2017, the Company’s efforts were focused on the development of therapeutics in 
the areas of dermatology and ophthalmology. We are currently conducting multiple discovery and preclinical research studies using our sd-rxRNA 
technology for use in developing immuno-oncology therapeutics and we have limited experience as a company in developing such immuno-
oncology technologies. Because of the number of companies and intense competition in immuno-oncology, we may not have the ability to 
successfully overcome many of the risks and uncertainties that companies face in this field.

We made a strategic decision to focus our development solely on immuno-oncology, and the anticipated benefits of our new strategic 

focus may not be realized. 

We acquired MirImmune, a privately-held immuno-oncology company, in the past year and are undertaking to divest our current 
dermatology and ophthalmology programs. In January 2018, the Company completed a thorough review of its business operations, development 
programs and financial resources and announced its strategic decision to solely focus the Company’s development portfolio on the field of immuno-
oncology. There is no assurance that the Company will be able to consummate any strategic transactions for the dermatology and ophthalmology 
programs or that we will be able to be successful in implementing our new focus as an immuno-oncology product development company.

If we are not successful in identifying and developing product candidates, we will not be able to commence clinical trials in humans or 

obtain approval for our product candidates. 

Our sd-rxRNA technology has been subject to only limited clinical testing with our first product candidate, RXI-109, for dermatologic and 
ophthalmic uses. We have identified lead compounds for preclinical development with our sd-rxRNA technology in immuno-oncology but have not 
yet commenced clinical testing. We may not be able to advance these or future product candidates through the preclinical stage into clinical trials. 
Additionally, we may not be able to identify data that would support entering these or future candidates into clinical trials. Furthermore, even if we 
successfully enter into clinical studies in immuno-oncology, the results from preclinical testing of a drug candidate may not predict the results that 
will be achieved in human clinical trials. There is no assurance that we will be able to successfully develop any product candidate(s), and we may 
focus our efforts and resources on product candidates that may prove to be unsuccessful.

We are dependent on the success of our product candidates, which may not receive regulatory approval or be successfully 

commercialized. 

We have no commercial products and currently generate no revenue from product sales or collaborations and may never be able to develop 

marketable products. The FDA or similar foreign governmental agencies must approve our products in development before they can be marketed. 
The process for obtaining FDA approval is both time consuming and costly, with no certainty of a successful outcome. Before obtaining regulatory 
approval for the sale of any drug candidate, we must conduct extensive preclinical tests and successful clinical trials to demonstrate the safety and 
efficacy of our product candidates in humans. A failure of any preclinical study or clinical trial can occur at any stage of testing. The results of 
preclinical and initial clinical testing of these products may not necessarily indicate the results that will be obtained from later or more extensive 
testing. Preliminary observations made in early stages of clinical trials with small numbers of subjects are inherently uncertain. Initial clinical trial 
results are not necessarily indicative of results that will be obtained when full data sets are analyzed or in subsequent clinical trials.

While there have been a number of immunotherapy drugs approved by the FDA, there have been no FDA drug approvals using the 
approach that we are taking. We will be subjected to thorough regulatory review by the FDA, and there is limited experience in this area with a few 
precedents. The FDA may require additional information from the Company regarding our current or planned clinical trials at any time, and such 
information may be costly to provide or cause potentially significant delays in development. There is no assurance that we will be able to 
successfully develop any of our product candidates, and we may spend large amounts of money trying to resolve these issues and may never 
succeed in doing so.

14

A number of different factors could prevent us from obtaining regulatory approval or commercializing our product candidates on a 

timely basis, or at all. 

We, the FDA or other applicable regulatory authorities, or an IRB may suspend clinical trials of a drug candidate at any time for various 

reasons, including if we or they believe the subjects participating in such trials are being exposed to unacceptable health risks. Among other reasons, 
adverse side effects of a drug candidate on subjects in a clinical trial could result in the FDA or other regulatory authorities suspending or 
terminating the trial and refusing to approve a particular drug candidate for any or all indications of use.

Clinical trials of a new drug candidate require the enrollment of a sufficient number of subjects, including subjects who are suffering from 

the disease or condition the drug candidate is intended to treat and who meet other eligibility criteria. Rates of subject enrollment are affected by 
many factors, and delays in subject enrollment can result in increased costs and longer development times.

Clinical trials also require the review and oversight of IRBs, which approve and continually review clinical investigations and protect the 

rights and welfare of human subjects. An inability or delay in obtaining IRB approval could prevent or delay the initiation and completion of clinical 
trials, and the FDA may decide not to consider any data or information derived from a clinical investigation not subject to initial and continuing IRB 
review and approval.

Numerous factors could affect the timing, cost or outcome of our drug development efforts, including the following:











Delays in filing or acceptance of initial drug applications for our product candidates;

Difficulty in securing centers to conduct clinical trials;

Conditions imposed on us by the FDA or comparable foreign authorities regarding the scope or design of our clinical trials;

Problems in engaging IRBs to oversee trials or problems in obtaining or maintaining IRB approval of studies;

Difficulty in enrolling subjects in conformity with required protocols or projected timelines;

Third-party contractors failing to comply with regulatory requirements or to meet their contractual obligations to us in a timely 
manner;

Our drug candidates having unexpected and different chemical and pharmacological properties in humans than in laboratory 
testing and interacting with human biological systems in unforeseen, ineffective or harmful ways;

The need to suspend or terminate clinical trials if the participants are being exposed to unacceptable health risks;

Insufficient or inadequate supply or quality of our drug candidates or other necessary materials necessary to conduct our clinical 
trials;

Effects of our drug candidates not having the desired effects or including undesirable side effects or the drug candidates having 
other unexpected characteristics;

The cost of our clinical trials being greater than we anticipate;

Negative or inconclusive results from our clinical trials or the clinical trials of others for similar drug candidates or inability to 
generate statistically significant data confirming the efficacy of the product being tested;

Changes in the FDA’s requirements for testing during the course of that testing;

Reallocation of our limited financial and other resources to other clinical programs; and

Adverse results obtained by other companies developing similar drugs.

15

It is possible that none of the product candidates that we may attempt to develop will obtain the appropriate regulatory approvals necessary 

to begin selling them or that any regulatory approval to market a product may be subject to limitations on the indicated uses for which we may 
market the product. The time required to obtain FDA and other approvals is unpredictable but often can take years following the commencement of 
clinical trials, depending upon the complexity of the drug candidate. Any analysis we perform of data from clinical activities is subject to 
confirmation and interpretation by regulatory authorities, which could delay, limit or prevent regulatory approval. Any delay or failure in obtaining 
required approvals could have a material adverse effect on our ability to generate revenue from the particular drug candidate.

We also are subject to numerous foreign regulatory requirements governing the conduct of clinical trials, manufacturing and marketing 
authorization, pricing and third-party reimbursement. The foreign regulatory approval process includes all of the risks associated with the FDA 
approval described above, as well as risks attributable to the satisfaction of local regulations in foreign jurisdictions. Approval by the FDA does not 
assure approval by regulatory authorities outside of the United States.

The FDA could impose a unique regulatory regime for our therapeutics. 

The compounds we intend to develop may represent a new class of drug, and even though the first RNAi therapeutic was approved in 

August 2018, the FDA has not yet established any definitive policies, practices or guidelines in relation to these drugs. While we expect any product 
candidates that we develop will be regulated as a new drug under the Federal Food, Drug, and Cosmetic Act, the FDA could decide to regulate them 
or other products we may develop as biologics under the Public Health Service Act. The lack of policies, practices or guidelines may hinder or slow 
review by the FDA of any regulatory filings that we may submit. Moreover, the FDA may respond to these submissions by defining requirements 
that we may not have anticipated.

Even if we receive regulatory approval to market our product candidates, our product candidates may not be accepted commercially, 

which may prevent us from becoming profitable. 

The product candidates that we are developing are based on new technologies and therapeutic approaches. For example, RNAi products 

may be more expensive to manufacture than traditional small molecule drugs, which may make them costlier than competing small molecule drugs. 
Additionally, RNAi products do not readily cross the so-called blood brain barrier, are rapidly eliminated from circulating blood and, for various 
applications, are likely to require injection or implantation, which will make them less convenient to administer than drugs administered orally. Key 
participants in the pharmaceutical marketplace, such as physicians, medical professionals working in large reference laboratories, public health 
laboratories and hospitals, third-party payors and consumers may not accept products intended to improve therapeutic results based on our 
technologies. As a result, it may be more difficult for us to convince the medical community and third-party payors to accept and use our products 
or to provide favorable reimbursement. If medical professionals working with large reference laboratories, public health laboratories and hospitals 
choose not to adopt and use our technologies, our products may not achieve broader market acceptance.

Additionally, although we expect that we will have intellectual property protection for our technology, certain governments may elect to 

deny patent protection for drugs targeting diseases with high unmet medical need (e.g., as in the case of HIV) and allow in their country 
internationally unauthorized generic competition. If this were to happen, our commercial prospects for developing any such drugs would be 
substantially diminished in these countries.

We are dependent on technologies we license, and if we lose the right to license such technologies or fail to license new technologies in 

the future, our ability to develop new products would be harmed. 

Many patents in the fields we are pursuing have already been exclusively licensed to third parties, including our competitors. If any of our 

existing licenses are terminated, the development of the products contemplated by the licenses could be delayed or terminated and we may not be 
able to negotiate additional licenses on acceptable terms, if at all, which would have a material adverse effect on our business.

16

We may be unable to protect our intellectual property rights licensed from other parties; our intellectual property rights may be 

inadequate to prevent third parties from using our technologies or developing competing products; and we may need to license additional 
intellectual property from others. 

Therapeutic applications of gene silencing technologies, formulations, delivery methods and other technologies that we license from third 
parties are claimed in a number of pending patent applications, but there is no assurance that these applications will result in any issued patents or 
that those patents would withstand possible legal challenges or protect our technologies from competition. The United States Patent and Trademark 
Office and patent granting authorities in other countries have upheld stringent standards for the RNAi patents that have been prosecuted so far. 
Consequently, pending patents that we have licensed and those that we own may continue to experience long and difficult prosecution challenges 
and may ultimately issue with much narrower claims than those in the pending applications. Third parties may hold or seek to obtain additional 
patents that could make it more difficult or impossible for us to develop products based on our technologies without obtaining a license to such 
patents, which licenses may not be available on attractive terms, or at all.

In addition, others may challenge the patents or patent applications that we currently license or may license in the future or that we own 

and, as a result, these patents could be narrowed, invalidated or rendered unenforceable, which would negatively affect our ability to exclude others 
from using the technologies described in these patents. There is no assurance that these patent or other pending applications or issued patents we 
license or that we own will withstand possible legal challenges. Moreover, the laws of some foreign countries may not protect our proprietary rights 
to the same extent as do the laws of the United States. Any patents issued to us or our licensors may not provide us with any competitive 
advantages, and there is no assurance that the patents of others will not have an adverse effect on our ability to do business or to continue to use our 
technologies freely. Our efforts to enforce and maintain our intellectual property rights may not be successful and may result in substantial costs and 
diversion of management time. Even if our rights are valid, enforceable and broad in scope, competitors may develop products based on technology 
that is not covered by our licenses or patents or patent applications that we own.

There is no guarantee that future licenses will be available from third parties for our product candidates on timely or satisfactory terms, or 
at all. To the extent that we are required and are able to obtain multiple licenses from third parties to develop or commercialize a product candidate, 
the aggregate licensing fees and milestones and royalty payments made to these parties may materially reduce our economic returns or even cause 
us to abandon development or commercialization of a product candidate.

Our success depends upon our ability to obtain and maintain intellectual property protection for our products and technologies.

The applications based on RNAi technologies claim many different methods, compositions and processes relating to the discovery, 

development, delivery and commercialization of RNAi therapeutics. Because this field is so new, very few of these patent applications have been 
fully processed by government patent offices around the world, and there is a great deal of uncertainty about which patents will issue, when, to 
whom and with what claims. Although we are not aware of any blocking patents or other proprietary rights, it is likely that there will be significant 
litigation and other proceedings, such as interference and opposition proceedings in various patent offices, relating to patent rights in the RNAi field. 
It is possible that we may become a party to such proceedings.

We are subject to significant competition and may not be able to compete successfully. 

The biotechnology and pharmaceutical industries, including immuno-oncology, have intense competition and contain a high degree of risk. 

We face a number of competitors that have substantially greater experience and greater research and development capabilities, staffing, financial, 
manufacturing, marketing, technical and other resources than us, and we may not be able to successfully compete with them. These companies 
include large and small pharmaceutical and biotechnology companies, academic institutions, government agencies and other private and public 
research organizations.

17

In addition, even if we are successful in developing our product candidates, in order to compete successfully we may need to be first to 
market or to demonstrate that our products are superior to therapies based on different technologies. Some of our competitors may develop and 
commercialize products that are introduced to market earlier than our product candidates or on a more cost-effective basis. A number of our 
competitors have already commenced clinical testing of product candidates and may be more advanced than we are in the process of developing 
products. If we are not first to market or are unable to demonstrate superiority, on a cost-effective basis or otherwise, any products for which we are 
able to obtain approval may not be successful.

Our competitors also compete with us in acquiring technologies complementary to our sd-rxRNA technology. We may face competition 
with respect to product efficacy and safety, ease of use and adaptability to modes of administration, acceptance by physicians, timing and scope of 
regulatory approvals, reimbursement coverage, price and patent position, including dominant patent positions of others. If we are not able to 
successfully obtain regulatory approval or commercialize our product candidates, we may not be able to establish market share and generate 
revenues from our technology.

We will rely upon third parties for the manufacture of our product candidates. 

We do not have the facilities or expertise to manufacture supplies of any of our potential product candidates. Accordingly, we will be 

dependent upon contract manufacturers to obtain supplies, and we will need to either develop, contract for, or otherwise arrange for the necessary 
manufacturers for these supplies. If for any reason we are unable to obtain the supplies for our product candidates from our current manufacturer, we 
would have to seek to obtain it from another major manufacturer. There is no assurance that we will be able to timely secure needed supply 
arrangements on satisfactory terms, or at all. Our failure to secure these arrangements as needed could have a material adverse effect on our ability 
to complete the development of our product candidates or, if we obtain regulatory approval for our product candidates, to commercialize them.

We may not be able to establish or maintain the third-party relationships that are necessary to develop or potentially commercialize 

some or all of our product candidates. 

We expect to depend on collaborators, partners, licensees, clinical research organizations and other third parties to support our discovery 

efforts, to formulate product candidates, to manufacture our product candidates and to conduct clinical trials for some or all of our product 
candidates. We cannot guarantee that we will be able to successfully negotiate agreements for or maintain relationships with collaborators, partners, 
licensees, clinical investigators, vendors and other third parties on favorable terms, if at all. Our ability to successfully negotiate such agreements 
will depend on, among other things, potential partners’ evaluation of the superiority of our technology over competing technologies, the quality of 
the preclinical and clinical data that we have generated and the perceived risks specific to developing our product candidates. If we are unable to 
obtain or maintain these agreements, we may not be able to clinically develop, formulate, manufacture, obtain regulatory approvals for or 
commercialize our product candidates. We cannot necessarily control the amount or timing of resources that our contract partners will devote to our 
research and development programs, product candidates or potential product candidates, and we cannot guarantee that these parties will fulfill their 
obligations to us under these arrangements in a timely fashion. We may not be able to readily terminate any such agreements with contract partners 
even if such contract partners do not fulfill their obligations to us.

We are subject to potential liabilities from clinical testing and future product liability claims. 

If any of our future products are alleged to be defective, they may expose us to claims for personal injury by subjects in clinical trials of our 

products. If our products are approved by the FDA, users may claim that such products caused unintended adverse effects. We will seek to obtain 
clinical trial insurance for clinical trials that we conduct, as well as liability insurance for any products that we market. There is no assurance that we 
will be able to obtain insurance in the amounts we seek, or at all. We anticipate that licensees who develop our products will carry liability insurance 
covering the clinical testing and marketing of those products. There is no assurance, however, that any insurance maintained by us or our licensees 
will prove adequate in the event of a claim against us. Even if claims asserted against us are unsuccessful, they may divert management’s attention 
from our operations and we may have to incur substantial costs to defend such claims.

18

Any drugs we develop may become subject to unfavorable pricing regulations, third-party reimbursement practices or healthcare 

reform initiatives, which could have a material adverse effect on our business. 

If approved, we intend to sell our products primarily to hospitals, oncologists and clinics, which receive reimbursement for the healthcare 

services they provide to their patients from third-party payors, such as Medicare, Medicaid and other domestic and international government 
programs, private insurance plans and managed care programs. Most third-party payors may deny reimbursement if they determine that a medical 
product was not used in accordance with cost-effective treatment methods, as determined by the third-party payor, was used for an unapproved 
indication or if they believe the cost of the product outweighs its benefits. Third-party payors also may refuse to reimburse for experimental 
procedures and devices. Furthermore, because our programs are still in development, we are unable at this time to determine their cost-effectiveness 
and the level or method of reimbursement for them. Increasingly, the third-party payors who reimburse patients are requiring that drug companies 
provide them with predetermined discounts from list prices and are challenging the prices charged for medical products. If the price we are able to 
charge for any products we develop is inadequate in light of our development and other costs, our profitability could be adversely affected.

We currently expect that any drugs we develop may need to be administered under the supervision of a physician. Under currently 

applicable law, drugs that are not usually self-administered may be eligible for coverage by the Medicare program if:









They are “incidental” to a physician’s services;

They are “reasonable and necessary” for the diagnosis or treatment of the illness or injury for which they are administered according 
to accepted standards of medical practice;

They are not excluded as immunizations; and

They have been approved by the FDA.

Insurers may refuse to provide insurance coverage for newly approved drugs, including drugs in our clinical pipeline, or insurance 

coverage may be delayed or be more limited than the purpose for which the drugs are approved by the FDA. Moreover, eligibility for insurance 
coverage does not imply that any drug will be reimbursed in all cases or at a rate that covers our costs, including research, development, 
manufacture, sale and distribution costs. Interim payments for new drugs, if applicable, may also not be sufficient to cover our costs and may not be 
made permanent. Reimbursement may be based on payments for other services and may reflect budgetary constraints or imperfections in Medicare 
data. 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 rates. Our inability to 
promptly obtain coverage and profitable reimbursement rates from both government-funded and private payors for new drugs that we develop could 
have a material adverse effect on our operating results, our ability to raise capital needed to develop products and our overall financial condition.

Additionally, third-party payors are increasingly attempting to contain healthcare costs by limiting both coverage and the level of 
reimbursement for medical products and services. Levels of reimbursement may decrease in the future, and future legislation, regulation or 
reimbursement policies of third-party payors may adversely affect the demand for and price levels of our products. If our customers are not 
reimbursed for our products, they may reduce or discontinue purchases of our products, which could have a material adverse effect on our business, 
financial condition and results of operations.

Comprehensive healthcare reform legislation, which became law in 2010, and any revisions to this legislation, could adversely affect our 
business and financial condition. Among other provisions, the legislation provides that a “biosimilar” product may be approved by the FDA on the 
basis of analytical tests and certain clinical studies demonstrating that such product is highly similar to an existing, approved product and that 
switching between an existing product and the biosimilar product will not result in diminished safety or efficacy. This abbreviated regulatory 
approval process may result in increased competition if we are able to bring a product to market. The legislation also includes more stringent 
compliance programs for companies in various sectors of the life sciences industry with which we may need to comply and enhanced penalties for 
non-compliance with the new healthcare regulations. Complying with new regulations may divert management resources, and inadvertent failure to 
comply with new regulations may result in penalties being imposed on us.

19

Some states and localities have established drug importation programs for their citizens, and federal drug import legislation has been 

introduced in Congress. The Medicare Prescription Drug Plan legislation, which became law in 2003, required the Secretary of Health and Human 
Services to promulgate regulations for drug reimportation from Canada into the United States under some circumstances, including when the drugs 
are sold at a lower price than in the United States. The Secretary, however, retained the discretion not to implement a drug reimportation plan, if the 
Secretary finds that the benefits do not outweigh the costs, and has so far declined to approve a reimportation plan. Proponents of drug reimportation 
may attempt to pass legislation that would directly allow reimportation under certain circumstances. Legislation or regulations allowing the 
reimportation of drugs, if enacted, could decrease the price we receive for any products that we may develop and adversely affect our future 
revenues and prospects for profitability.

With the current U.S. administration and Congress, there may be additional legislative changes, including repeal and replacement of certain 
provisions of the Affordable Care Act. It remains to be seen, however, precisely what new legislation will provide, when it will be enacted and what 
impact it will have on the availability of healthcare and containing or lowering the cost of healthcare. Such reforms could have an adverse effect on 
anticipated revenue from product candidates that we may successfully develop and for which we may obtain marketing approval and may affect our 
overall financial condition and ability to develop product candidates.

Even if we obtain regulatory approvals, our marketed drugs will be subject to ongoing regulatory review. If we fail to comply with 
continuing U.S. and foreign regulations, we could lose our approvals to market drugs and our business would be materially and adversely 
affected. 

Following regulatory approval of any drugs we may develop, we will remain subject to continuing regulatory review, including the review 

of adverse drug experiences and clinical results that are reported after our drug products are made available to patients. This would include results 
from any post-marketing tests or vigilance required as a condition of approval. The manufacturer and manufacturing facilities we use to make any of 
our drug products will also be subject to periodic review and inspection by the FDA. The discovery of any new or previously unknown problems 
with the product, manufacturer or facility may result in restrictions on the drug or manufacturer or facility, including withdrawal of the drug from 
the market. We would continue to be subject to the FDA requirements governing the labeling, packaging, storage, advertising, promotion, 
recordkeeping and submission of safety and other post-market information for all of our product candidates, even those that the FDA had approved. 
If we fail to comply with applicable continuing regulatory requirements, we may be subject to fines, suspension or withdrawal of regulatory 
approval, product recalls and seizures, operating restrictions and other adverse consequences.

If we fail to attract, hire and retain qualified personnel, we may not be able to design, develop, market or sell our products or 

successfully manage our business. 

Our business prospects are dependent on the principal members of our executive team, the loss of whose services could make it difficult for 

us to manage our business successfully and achieve our business objectives. While we have entered into employment agreements with each of our 
executive officers, they could leave at any time, in addition to our other employees, who are all “at will” employees. Our ability to identify, attract, 
retain and integrate additional qualified key personnel is also critical to our success. Competition for skilled research, product development, 
regulatory and technical personnel is intense, and we may not be able to recruit and retain the personnel we need. The loss of the services of any key 
research, product development, regulatory and technical personnel, or our inability to hire new personnel with the requisite skills, could restrict our 
ability to develop our product candidates.

Risks Relating to Our Financial Condition 

We may not be able to obtain sufficient financing and may not be able to develop our product candidates. 

We believe that our existing cash will likely be sufficient to fund our currently planned operations for at least the next 12 months. 

However, we have generated significant losses to date, have not generated any product revenue and may not generate product revenue in the 
foreseeable future, or ever. We expect to incur significant operating losses as we advance our product candidates through drug development and the 
regulatory process. In the future, we may need to issue equity or incur debt in order to fund our planned expenditures, as well as to make 
acquisitions and other investments. We cannot assure you that equity or debt financing will be available to us on acceptable terms, or at all. If we 
cannot, or are limited in the ability to, issue equity, incur debt or enter into strategic collaborations, we may be unable to fund the discovery and 
development of our product candidates, address gaps in our product offerings or improve our technology.

20

We anticipate that we will need to raise substantial amounts of money to fund a variety of future activities integral to the development of 

our business, which may include but is not limited to the following:

 To conduct research and development to successfully develop our technologies;

 To obtain regulatory approval for our products;

 To file and prosecute patent applications and to defend and assess patents to protect our technologies;

 To retain qualified employees, particularly in light of intense competition for qualified personnel;

 To manufacture products ourselves or through third parties;

 To market our products, either through building our own sales and distribution capabilities or relying on third parties; and

 To acquire new technologies, licenses or products.

If we fail to obtain additional funding when needed, we may ultimately be unable to continue to develop and potentially commercialize our 

product candidates, and we may be forced to scale back or terminate our operations or seek to merge with or be acquired by another company.

Future financing may be obtained through, and future development efforts may be paid for by, the issuance of debt or equity, which 

may have an adverse effect on our stockholders or may otherwise adversely affect our business. 

If we raise funds through the issuance of debt or equity, any debt securities or preferred stock issued will have rights, preferences and 

privileges senior to those of holders of our common stock in the event of a liquidation. In such event, there is a possibility that once all senior claims 
are settled, there may be no assets remaining to pay out to the holders of common stock. In addition, if we raise funds through the issuance of 
additional equity, whether through private placements or public offerings, such an issuance would dilute current stockholders’ ownership in us.

The terms of debt securities may also impose restrictions on our operations, which may include limiting our ability to incur additional 

indebtedness, to pay dividends on or repurchase our capital stock, or to make certain acquisitions or investments. In addition, we may be subject to 
covenants requiring us to satisfy certain financial tests and ratios, and our ability to satisfy such covenants may be affected by events outside of our 
control.

We expect to continue to incur significant research and development expenses, which may make it difficult for us to attain profitability, 

and may lead to uncertainty as to our ability to continue as a going concern. 

We expend substantial funds to develop our technologies, and additional substantial funds will be required for further research and 
development, including preclinical testing and clinical trials of any product candidates, and to manufacture and market any products that are 
approved for commercial sale. Because the successful development of our products is uncertain, we are unable to precisely estimate the actual funds 
we will require to develop and potentially commercialize them. In addition, we may not be able to generate enough revenue, even if we are able to 
commercialize any of our product candidates, to become profitable.

21

If we are unable to achieve or sustain profitability or to secure additional financing, we may not be able to meet our obligations as they 

come due, raising substantial doubts as to our ability to continue as a going concern. Any such inability to continue as a going concern may result in 
our common stockholders losing their entire investment. There is no guarantee that we will become profitable or secure additional financing. Our 
financial statements do not include any adjustments to, or classification of, recorded asset amounts and classification of liabilities that might be 
necessary if we were unable to continue as a going concern. Changes in our operating plans, our existing and anticipated working capital needs, the 
acceleration or modification of our expansion plans, increased expenses, potential acquisitions or other events will all affect our ability to continue 
as a going concern.

Risks Relating to Our Securities 

The price of our common stock has been and may continue to be volatile. 

The stock markets, in general, and the markets for drug delivery and pharmaceutical company stocks, in particular, have experienced 

extreme volatility that has often been unrelated to the operating performance of particular companies. These broad market fluctuations may 
adversely affect the trading price of our common stock. In addition, the limited trading volume of our stock may contribute to its volatility.

In the past, following periods of volatility in the market price of a particular company’s securities, litigation has often been brought against 
that company. If litigation of this type is brought against us, it could be extremely expensive and divert management’s attention and the Company’s 
resources.

We have issued preferred stock in the past and possibly may issue more preferred stock in the future, and the terms of the preferred 

stock may reduce the value of our common stock. 

We are authorized to issue up to 10,000,000 shares of preferred stock in one or more series. Our Board of Directors may determine the 
terms of future preferred stock offerings without further action by our stockholders. The issuance of our preferred stock could affect the rights of 
existing stockholders or reduce the value of our outstanding preferred stock or common stock. In particular, rights granted to holders of certain 
series of preferred stock may include voting rights, preferences as to dividends and liquidation, conversion and redemption rights and restrictions on 
our ability to merge with or sell our assets to a third party.

We may acquire other businesses or form joint ventures that may be unsuccessful and could dilute your ownership interest in the 

Company. 

As part of our business strategy, we may pursue future acquisitions of other complementary businesses and technology licensing 
arrangements. We also may pursue strategic alliances. We have limited experience with respect to acquiring other companies and with respect to the 
formation of collaborations, strategic alliances and joint ventures. We may not be able to integrate such acquisitions successfully into our existing 
business, and we could assume unknown or contingent liabilities. We also could experience adverse effects on our reported results of operations 
from acquisition related charges, amortization of acquired technology and other intangibles and impairment charges relating to write-offs of 
goodwill and other intangible assets from time to time following the acquisition. Integration of an acquired company requires management resources 
that otherwise would be available for ongoing development of our existing business. We may not realize the anticipated benefits of any acquisition, 
technology license or strategic alliance. For example, in January 2017, the Company acquired 100% of the outstanding capital stock of MirImmune. 
The assets and development programs acquired from MirImmune were at an early stage of development and will require significant investment of 
time and capital if we are to be successful in developing them. There is no assurance that we will be successful in developing such assets, and a 
failure to successfully develop such assets could diminish our prospects.

To finance future acquisitions, we may choose to issue shares of our common stock or preferred stock as consideration, which would dilute 

current stockholders’ ownership interest in us. Alternatively, it may be necessary for us to raise additional funds through public or private 
financings. Additional funds may not be available on terms that are favorable to us and, in the case of equity financings, may result in dilution to our 
stockholders. Any future acquisitions by us also could result in large and immediate write-offs, the incurrence of contingent liabilities or 
amortization of expenses related to acquired intangible assets, any of which could harm our operating results.

22

We do not anticipate paying cash dividends in the foreseeable future. 

Our business requires significant funding. We currently plan to invest all available funds and future earnings in the development and 

growth of our business and do not anticipate paying any cash dividends on our common stock in the foreseeable future. As a result, capital 
appreciation, if any, of our common stock will be the sole source of potential gain for our stockholders for the foreseeable future.

We may not be able to regain compliance with the continued listing requirements of The Nasdaq Capital Market.

On November 12, 2018, we received written notice (the “Notification Letter”) from the Nasdaq Stock Market (“Nasdaq”) notifying us 
that we are not in compliance with the minimum bid price requirements set forth in Nasdaq Listing Rule 5550(a)(2) for continued listing on The 
Nasdaq Capital Market. Nasdaq Listing Rule 5550(a)(2) requires listed securities to maintain a minimum bid price of $1.00 per share, and Listing 
Rule 5810(c)(3)(A) provides that a failure to meet the minimum bid price requirement exists if the deficiency continues for a period of 30 
consecutive business days. Based on the closing bid price of our common stock for the 30 consecutive business days prior to the date of the 
Notification Letter, we no longer meet the minimum bid price requirement.

The Notification Letter does not impact our listing on The Nasdaq Capital Market at this time. The Notification Letter states that we have 

180 calendar days, or until May 13, 2019, to regain compliance with Nasdaq Listing Rule 5550(a)(2). To regain compliance, the bid price of our 
common stock must have a closing bid price of at least $1.00 per share for a minimum of 10 consecutive business days at any time prior to May 13, 
2019. In the event that we do not regain compliance by May 13, 2019, we may be eligible for additional time to reach compliance with the 
minimum bid price requirement. However, if we fail to regain compliance with the minimum bid price listing requirement or fail to maintain 
compliance with all other applicable continued listing requirements and Nasdaq determines to delist our common stock, the delisting could 
adversely impact us by, among other things, reducing the liquidity and market price of our common stock; reducing the number of investors willing 
to hold or acquire our common stock; limiting our ability to issue additional securities in the future; and limiting our ability to fund our operations.

Provisions of our certificate of incorporation and bylaws and Delaware law might discourage, delay or prevent a change of control of 

the Company or changes in our management and, as a result, depress the trading price of our common stock. 

Our certificate of incorporation and bylaws contain provisions that could discourage, delay or prevent a change of control of the Company 

or changes in our management that the stockholders of the Company may deem advantageous. These provisions:

 Authorize the issuance of “blank check” preferred stock that our Board of Directors could issue to increase the number of outstanding 

shares and to discourage a takeover attempt;

 Prohibit stockholder action by written consent, which requires all stockholder actions to be taken at a meeting of our stockholders;

 Provide that the Board of Directors is expressly authorized to adopt, alter or repeal our bylaws; and

 Establish advance notice requirements for nominations for election to our Board of Directors or for proposing matters that can be acted 

upon by stockholders at stockholder meetings.

Although we believe these provisions collectively provide for an opportunity to receive higher bids by requiring potential acquirers to 
negotiate with our Board of Directors, they would apply even if the offer may be considered beneficial by some stockholders. In addition, these 
provisions may frustrate or prevent any attempts by our stockholders to replace or remove our current management team by making it more difficult 
for stockholders to replace members of our Board of Directors, which is responsible for appointing the members of our management.

23

Moreover, because we are incorporated in Delaware, we are governed by the provisions of Section 203 of the Delaware General 
Corporation Law, which prohibits a person who owns in excess of 15% of our outstanding voting stock from merging or combining with us for a 
period of three years after the date of the transaction in which the person acquired in excess of 15% of our outstanding voting stock, unless the 
merger or combination is approved in a prescribed manner.

PROPERTIES 

On December 17, 2013, we entered into a lease (the “Lease”) with 257 Simarano Drive, LLC, Brighton Properties, LLC, Robert 
Stubblebine 1, LLC and Robert Stubblebine 2, LLC to lease office and laboratory space in the building known as the “Main Building” located at 
257 Simarano Drive, Marlborough, Massachusetts, covering approximately 7,581 square feet. The premises are used by the Company for office and 
laboratory space. The term of the Lease commenced on April 1, 2014 and continues for five years, expiring on March 31, 2019.

On January 22, 2019, the Company executed a First Amendment (the “First Amendment”) to the Lease. The First Amendment extended 

the Lease term commencing on April 1, 2019 for five years (the “Extension Term”). The base rent for the premises during the first year of the 
Extension Term is $124,864.78 per annum, payable monthly. Each year thereafter, the base rent shall increase by approximately 3% over the base 
rent from the prior year. With six months’ advance notice, either party may terminate the lease on March 31, 2021, paying the non-terminating party 
six months’ rent as a penalty or on March 31, 2022, paying the non-terminating party three months’ rent as a penalty.

We believe that our facilities are suitable for our current needs.

MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS 

The following discussion of our financial condition and results of operations should be read in conjunction with our consolidated financial 
statements and the notes to those consolidated financial statements included in Item 8 of this Annual Report on Form 10-K. This discussion contains 
forward-looking statements that involve significant risks and uncertainties. As a result of many factors, such as those set forth under “Risk Factors” 
and elsewhere in this Annual Report on Form 10-K, our actual results may differ materially from those anticipated in these forward-looking 
statements. Please refer to the discussion under the heading “Forward-Looking Statements” above.

Overview 

Phio Pharmaceuticals Corp. is a biotechnology company developing the next generation of immuno-oncology therapeutics based on our 

self-delivering RNAi (“sd-rxRNA®”) therapeutic platform. The Company’s efforts are focused on developing sd-rxRNA therapeutic compounds to 
be used in the context of adoptive cell transfer by targeting checkpoints or other gene targets, or to be used in immunotherapy following intra-
tumoral injections. We aim to maximize the power of our sd-rxRNA therapeutic compounds by weaponizing therapeutic immune effector cells to 
attack cancer, and to make tumors more susceptible to such attacks, and ultimately provide patients battling cancers with a powerful new treatment 
option that goes beyond current treatment modalities.

Prior to the Company’s acquisition of MirImmune, Inc. (“MirImmune”), our principal activities consisted of the preclinical and clinical 

development of the Company’s sd-rxRNA compounds and topical immunotherapy agent in the areas of dermatology and ophthalmology. In January 
2018, after a thorough review of its business operations, development programs and financial resources, the Company made a strategic decision to 
focus its efforts solely on immuno-oncology to accelerate growth and support a potential return on investment for its stockholders. In connection 
with this decision, the Company completed all open clinical trials in dermatology and ophthalmology with RXI-109, our first sd-rxRNA clinical 
candidate, and Samcyprone®, and reported out on the results of those clinical studies in 2018. The Company intends to seek a partner and/or out-
licensee for its dermatology program and its ophthalmology program to continue with their development. The Company’s current business strategy 
solely focuses on the development of immuno-oncology therapeutics utilizing our proprietary sd-rxRNA technology.

On November 19, 2018, the Company changed its name from RXi Pharmaceuticals Corporation to Phio Pharmaceuticals Corp., which 

reflects the Company’s transition from a platform company to one that is fully committed to develop groundbreaking immuno-oncology 
therapeutics. 

26

Our development efforts are based on our broadly patented sd-rxRNA technology platform. Our sd-rxRNA compounds do not require a 
delivery vehicle to penetrate into tissues and cells and are designed to “silence,” or down-regulate, the expression of a specific gene that may be 
over-expressed in a disease condition. We believe that our sd-rxRNA platform uniquely positions the Company in the field of immuno-oncology 
because of this and for the following reasons:

 Our sd-rxRNA compounds do not require facilitated delivery (mechanical or formulation);



Can target multiple genes (i.e. multiple immunosuppression pathways) in a single therapeutic entity;

 Demonstrate efficient uptake of sd-rxRNA to immune cells;







Silencing by sd-rxRNA has been shown to have a sustained, or long-term, effect in vivo;

Favorable clinical safety profile of sd-rxRNA with local administration; and

Can be readily manufactured under current good manufacturing practices.

On January 3, 2018, the Board of Directors of the Company approved a 1-for-10 reverse stock split of the Company’s outstanding common 

stock, which was effected on January 8, 2018. All share and per share amounts have been retroactively adjusted for all periods presented to give 
effect to the reverse stock split, including reclassifying an amount equal to the reduction in par value to additional paid-in capital in the financial 
statements.

Checkpoint Inhibition in Adoptive Cell Transfer 

The Company has developed sd-rxRNA targeting PD-1, TIGIT and other undisclosed checkpoints in adoptive cell transfer (“ACT”) for the 

treatment of solid tumors. RXI-762 and RXI-804, sd-rxRNA compounds that are designed to suppress the expression of immune checkpoint 
proteins PD-1 and TIGIT, respectively, which, when used in ACT, are expected to result in an improved efficacy to the targeted tumors. We expect 
to enter clinical development with RXI-762, our most advanced program, as part of an ACT therapy for solid tumors in melanoma by the end of 
2019.

The Center for Cancer Immune Therapy (CCIT) at Herlev Hospital is a leading European cancer center for use of tumor-infiltrating 

lymphocytes (“TILs”) for ACT. CCIT has carried out numerous clinical trials based on a direct translation of the discoveries from the laboratory. 
Our collaboration with CCIT is evaluating the potential of our sd-rxRNA technology platform to enhance the function of TILs for use in the 
treatment for a number of cancer types, including melanoma and ovarian cancer. To date, CCIT has evaluated sd-rxRNA compounds targeting 
immune checkpoints in preclinical screening models of matched TIL/tumor cell pairs from melanoma and cancer patients. Results have shown a 
marked PD-1 reduction on the surface of TILs in a pilot rapid expansion protocol.

Iovance Biotherapeutics, Inc. is a biotechnology company focused on the development and commercialization of autologous cellular 

immunotherapies optimizing personalized, tumor-directed TILs. Our research collaboration with Iovance will evaluate the potential synergies with 
our novel sd-rxRNA therapeutic compounds and Iovance’s autologous cell therapy based on TILs for the use in the treatment of cancer. Data from 
this collaboration has shown that a sd-rxRNA mediated knock-down of PD-1 was associated with phenotypic changes indicative of TIL activation. 
Our next steps with Iovance include further evaluation of the impact of sd-rxRNA mediated gene silencing on TIL tumor reactivity and 
implementation of optimized silencing protocols and scale-up thereof.

27

Cell Maturation and Metabolism in Adoptive Cell Transfer

We use our sd-rxRNA in T-cells and other immune cell types, such as natural killer (“NK”) cells and dendritic cells, for targets other than 
immune checkpoints in order to weaponize and improve cell persistence and cell viability in the immunosuppressive tumor micro-environment. We 
believe this shows the broad applicability of our platform technology, and that our potential impact in immuno-oncology is not limited to 
checkpoints and TILs.

We have shown that sd-rxRNAs are rapidly and efficiently taken up by immune effector cells without the use of transfection reagents. 

Using sd-rxRNA compounds against checkpoint inhibitors, we can suppress their expression levels up to 95% in immune cells, including T-cells 
and NK cells. Furthermore, we have demonstrated potent silencing activity as well as a phenotypic effect (enhanced degranulation activity) of NK 
cells treated with sd-rxRNA compounds targeting checkpoints. By treating NK cells ex-vivo, prior to ACT with sd-rxRNA reducing the expression 
of proteins such as Cbl-b and TIGIT, the anti-tumor response of these cells can be improved. Ongoing work expands these findings to include 
compounds for more specific NK targets, including NK specific inhibitory receptors, which could be used alone or in combination.

Through our collaboration with Medigene AG, a German biotechnology company developing highly innovative, complementary treatment 

platforms to target various types and stages of cancer, we are exploring the potential synergies of our sd-rxRNA technology in combination with 
Medigene’s recombinant TCRs to develop modified T-cells with enhanced efficacy and/or safety with the ultimate goal to further improve 
Medigene’s T-cell therapies for the treatment of cancer patients. In the studies completed, Medigene observed the reduction of PD-1 surface levels 
in T-cells transduced with TCRs and treated with our sd-rxRNA compound, RXI-762. While these studies utilized the Company’s PD-1 targeting 
sd-rxRNA for proof of concept, there is also the potential to expand the collaboration to additional targets and the two complementing technologies 
could lead to synergistic effects that might further sharpen and improve the therapeutic effects of Medigene’s receptor modified T-cells.

Direct Tumor and Tumor Micro-Environment 

Our third focus area includes the use of our sd-rxRNA directly towards tumor and/or tumor micro-environment (“TME”) targets. 
Impacting the tumor cells and/or TME through a direct use of sd-rxRNA, such as via intra-tumoral injection, could potentially become an important 
form of adjuvant therapy. We believe that this will also show that our contributions with our sd-rxRNA compounds in immuno-oncology are not 
limited to use with another company’s cell platform. Additionally, the Company has shown that its sd-rxRNA compounds are safe and well-
tolerated via intradermal injections and injections in the eye through its completed clinical trials with RXI-109 in dermatology and ophthalmology.

Our collaborative research agreement with Gustave Roussy, a leading comprehensive cancer center in France, concentrates on determining 

the feasibility of our sd-rxRNA platform to target the TME via intra-tumoral injection. The goal of our recent in-vivo study with Gustave Roussy 
was to demonstrate sd-rxRNA compound delivery via intra-tumoral injection and demonstrate activity (silencing of gene expression) of sd-rxRNA 
compounds. Results from this study showed an 80—85% reduction of the target gene expression in a mouse model of melanoma via intra-tumoral 
injection.

Dermatology and Ophthalmology

The Company intends to seek a partner and/or out-licensee for both its dermatology and ophthalmology programs, which includes RXI-109 

and Samcyprone, to continue their development. During 2018, the Company reported the results from its completed clinical trials in dermatology 
and ophthalmology with RXI-109 and Samcyprone.

28





In December 2017, the Company announced positive results with RXI-109 in a Phase 2 open-label, multi-center, prospective, 
within-subject controlled study evaluating the effectiveness and safety of RXI-109 on the outcome of scar revision surgery for 
hypertrophic scars in healthy adults. The primary effectiveness objective was met as shown by a statistically significant improved 
visual appearance of revised scars after scar revision surgery and treatment with RXI-109 versus control, as assessed by the 
investigator. The full study results showed that the product was safe and well tolerated for all dosage groups. Exploratory endpoint 
analysis furthermore showed that the cosmetic outcomes of RXI-109 treated scars were highly preferred over the untreated revised 
scars, by both investigators and patients.

In May 2018, the Company announced results from our Phase 2 clinical trial with Samcyprone in cutaneous warts. The primary 
effectiveness objectives were met as shown by high levels of immunotherapeutic response and therapeutic response. The 
immunotherapeutic response rate – a prerequisite for therapeutic response – was 97.7% across all 88 subjects enrolled in the study. 
From a therapeutic response viewpoint, with once weekly dosing for up to 10 weeks, more than 70% of all warts showed a positive 
wart response rate, i.e. reduction of wart size of more than 50%. Complete wart clearance throughout the study was 54% for all 
warts, and up to 71.4% for certain wart types (non-plantar warts). The study results show furthermore that Samcyprone was safe and 
well tolerated.

In August 2018, the Company announced positive results from our Phase 1/2 clinical trial to evaluate the safety and clinical activity 
of RXI-109 in reducing the progression of retinal scarring. The trial was a multi-dose, dose escalation study conducted in subjects 
with wet age-related macular degeneration with evidence of subretinal fibrosis. Each subject in the study received four doses of 
RXI-109 by intraocular injection at one-month intervals for a total dosing period of three months. The primary objective was met as 
shown by the absence of dose-limiting and serious toxicities, and only mild to moderate procedure related adverse events. None of 
the adverse events were drug related. In addition, comprehensive ocular examinations showed no indications of inflammation nor 
any other tolerability issues related to the treatment. The secondary objective of the study was also met with improved or stable 
disease in the study eyes of several subjects.

On April 11, 2018, the Company closed a registered direct offering of 1,510,604 shares of the Company’s common stock at a purchase 

price of $3.15 per share (the “April 2018 Offering”) pursuant to the Securities Purchase Agreement dated as of April 9, 2018. In a concurrent 
private placement, the Company sold warrants (the “April 2018 Warrants”) to purchase a total of 1,132,953 shares of common stock at a purchase 
price of $0.125 per underlying warrant share and with an exercise price of $3.15 per share (the “Private Placement”). Net proceeds to the Company 
from the April 2018 Offering and Private Placement were $4,210,000 after deducting placement agent fees and offering expenses paid by the 
Company. In connection with the April 2018 Offering and Private Placement, the Company issued warrants to purchase a total of 75,530 shares of 
common stock with an exercise price of $4.0546 per share to the placement agent, H.C. Wainwright & Co., LLC (“HCW”).

On October 3, 2018, the Company closed an underwritten public offering (the “October 2018 Offering”) of (i) 3,725,714 units (the 

“Units”), at a public offering price of $0.70 per Unit, with each Unit consisting of one share of common stock and one warrant (the “October 2018 
Warrants”) to purchase one share of common stock and (ii) 17,702,858 pre-funded units (the “Pre-Funded Units”), at a public offering price of 
$0.69 per Pre-Funded Unit, with each Pre-Funded Unit consisting of one pre-funded warrant (the “Pre-Funded Warrants”) to purchase one share 
of common stock and one October 2018 Warrant. The October 2018 Warrants included in the Units and Pre-Funded Units are immediately 
exercisable at a price of $0.70 per share and expire seven years from the date of issuance. The Pre-Funded Warrants included in the Pre-Funded 
Units are immediately exercisable at a price per share of $0.01 and do not expire. Net proceeds from the October 2018 Offering were $13,193,000 
after deducting underwriting discounts and commissions and offering expenses paid by the Company. Additionally, pursuant to the October 2018 
Offering, the Company issued warrants to purchase up to 1,607,143 shares of common stock at an exercise price of $0.875 per share to the 
underwriter, HCW.

Critical Accounting Policies and Estimates 

The discussion and analysis of our financial condition and results of operations is based upon our financial statements, which have been 

prepared in accordance with United States generally accepted accounting principles (“GAAP”). The preparation of these financial statements 
requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses, and related disclosure of 
contingent assets and liabilities. On an ongoing basis, we evaluate our estimates and base our estimates on historical experience and various other 
assumptions that are believed to be reasonable under the circumstances. Actual results may differ from these estimates under different assumptions 
or conditions and could have a material impact on our reported results. While our significant accounting policies are more fully described in the 
notes to our consolidated financial statements included elsewhere in this Annual Report, we believe the following accounting policies to be the most 
critical in understanding the judgments and estimates we use in preparing our financial statements.

Preclinical and Clinical Expenses

Preclinical and clinical trial expenses relate to estimates of costs incurred and fees connected with clinical trial sites, third-party clinical 

research organizations and other preclinical and clinical related activities and include such items as subject-related fees, laboratory work, 
investigator fees and analysis costs. Costs associated with these expenses are generally payable on the passage of time or when certain milestones 
are achieved. Expense is recorded during the period incurred or in the period in which a milestone is achieved. In order to ensure that we have 
adequately provided for preclinical and clinical expenses during the proper period, we maintain an accrual to cover these expenses. These accruals 
are assessed on a quarterly basis and are based on such assumptions as expected total cost, the length of the study, timing of certain milestones and 
other information available to us.

Stock-based Compensation

The Company follows the provisions of the Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) 
Topic 718, “Compensation – Stock Compensation” (“ASC 718”), which requires the measurement and recognition of compensation expense for all 
stock-based payment awards. Stock compensation expense based on the grant date fair value estimated in accordance with the provisions of ASC 
718 is recognized as an expense over the requisite service period. Determining the amount of stock-based compensation to be recorded requires us 
to develop highly subjective estimates to be used in calculating the grant date fair value of stock options. We use the Black-Scholes option pricing 
model to value our option grants and determine the related compensation expense. The use of the model requires us to make estimates of the 
following assumptions:

Expected volatility — The Company’s expected stock price volatility assumption is based upon the Company’s own implied volatility.

Expected term — We use the simplified method to estimate the expected term assumption. The simplified method is based on the vesting 

period and the contractual term for each grant, or for each vesting-tranche for awards with graded vesting.

Risk-free interest rate — The yield on zero-coupon U.S. Treasury securities for a period that is commensurate with the expected term 

assumption is used as the risk-free interest rate.

Dividend yield — We utilize a dividend yield of zero based on the fact that we have never paid cash dividends and currently have no 

intention to pay cash dividends.

The scope of ASC 718 was expanded to include share-based payment transactions for acquiring goods and services from non-employees.

Derivative Financial Instruments

During the normal course of business we may issue warrants to vendors as consideration to perform services. We may also issue warrants 
as part of a debt or equity financing. Warrants and other derivative financial instruments are accounted for either as equity or as an asset or liability, 
depending on the characteristics of each derivative financial instrument. Warrants classified as equity are measured at fair value and recorded as 
additional paid in capital in stockholders’ equity at the date of issuance. No further adjustments to their valuation are made. Derivative financial 
instruments classified as an asset or liability are measured at fair value on the issuance date and are revalued on each subsequent balance sheet date. 
The changes in the fair value are recognized as current period income or loss.

Financial Operations Overview

Revenues

To date, we have primarily generated revenues through government grants. We have not generated any commercial product revenue.

In the future, we may generate revenue from a combination of government grants, research and development agreements, license fees and 
other upfront payments, milestone payments, product sales and royalties in connection with future strategic collaborators and partners. We expect 
that any revenue we generate will fluctuate from period to period as a result of the timing of the achievement of any preclinical, clinical or 
commercial milestones and the timing and amount of payments received relating to those milestones and the extent to which any of our product 
candidates are approved and successfully commercialized by us or strategic collaborators and partners. If the Company or any future partner fails to 
develop product candidates in a timely manner or obtain regulatory approval for them, then our ability to generate future revenue and our results of 
operations and financial position would be adversely affected.

Research and Development Expenses 

Research and development expenses relate to salaries, employee benefits, facility-related expenses, supplies, stock-based compensation 

related to employees and non-employees involved in the Company’s research and development, external services, other operating costs and 
overhead related to our research and development departments, costs to acquire technology licenses and expenses associated with our preclinical 
activities and clinical trials. Research and development expenses are charged to expense as incurred. Payments made by the Company in advance for 
research and development services not yet provided and/or for materials not yet received are recorded as prepaid expenses and expensed when the 
service has been performed or when the goods have been received.

Our research and development programs are focused on the development of the next generation of immuno-oncology therapeutics based on 

sd-rxRNA therapeutic platform. Prior to the Company’s acquisition of MirImmune in January 2017, our research and development programs 
primarily focused on developing our sd-rxRNA compounds and our topical immunotherapy agent against therapeutically relevant targets in the 
fields of dermatology and ophthalmology. Since we commenced operations, research and development has composed a significant portion of our 
total operating expenses and is expected to compose the majority of our spending for the foreseeable future.

31

There are risks in any new field of drug discovery that preclude certainty regarding the successful development of a product. We cannot 

reasonably estimate or know the nature, timing and costs of the efforts necessary to complete the development of, or the period in which material net 
cash inflows are expected to commence from, any product candidate. Our inability to make these estimates results from the uncertainty of numerous 
factors, including but not limited to:

 Our ability to advance product candidates into preclinical research and clinical trials;





















The scope and rate of progress of our preclinical program and other research and development activities;

The scope, rate of progress and cost of any clinical trials we commence;

The cost of filing, prosecuting, defending and enforcing patent claims and other intellectual property rights;

Clinical trial results;

The terms and timing of any collaborative, licensing and other arrangements that we may establish;

The cost and timing of regulatory approvals;

The cost of establishing clinical and commercial supplies of our product candidates and any products that we may develop;

The cost and timing of establishing sales, marketing and distribution capabilities;

The effect of competing technological and market developments; and

The effect of government regulation and insurance industry efforts to control healthcare costs through reimbursement policy and other 
cost management strategies.

Failure to complete any stage of the development of our product candidates in a timely manner could have a material adverse effect on our 

results of operations, financial position and liquidity.

Acquired In-Process Research and Development

Assets purchased in an asset acquisition transaction are expensed as in-process research and development unless the assets acquired have 

an alternative future use. Acquired in-process research and development payments are immediately expensed and include upfront payments, as well 
as transaction fees and subsequent milestone payments. Development costs incurred after the acquisition are expensed as incurred.

General and Administrative Expenses 

General and administrative expenses relate to salaries, employee benefits, facility-related expenses, and stock-based compensation expense 

related to employees dedicated to general and administrative activities. Other general and administrative expenses include professional fees for 
legal, audit, tax and consulting services, as well as other general corporate expenses.

32

Other Income (Expense), net 

Other income (expense) consists primarily of interest income and expense and various income or expense items of a non-recurring nature.

Research and Development Expenses 

Research and development expenses for the year ended December 31, 2018 decreased 19% compared with the year ended December 31, 

2017, primarily due to the completion of the work in the Company’s dermatology and ophthalmology programs, including clinical trial-related and 
manufacturing-related expenses, and a decrease in payroll expenses due to a reduction in headcount as compared with the prior year period.

Acquired In-process Research and Development Expense 

The Company did not complete an asset acquisition transaction during the year ended December 31, 2018 that would require the recording 

of acquired in-process research and development expense. Total acquired in-process research and development expense for the year ended 
December 31, 2017 was $4,696,000, and related to the fair value of consideration given, which includes transaction costs, liabilities assumed and 
cancellation of notes receivable, and the deferred tax impact of the Company’s acquisition of MirImmune.

General and Administrative Expenses 

General and administrative expenses for the year ended December 31, 2018 decreased 21% compared with the year ended December 31, 
2017, primarily due to a decrease in payroll expenses due to a reduction in headcount as compared with the prior year period, as well as a decrease 
in professional fees for legal-related services.

Income Tax

There was no income tax expense or benefit during the year ended December 31, 2018. For the year ended December 31, 2017, we 

recognized an income tax benefit of $1,621,000 for the tax-related impact of the Company’s acquisition of MirImmune.

Liquidity and Capital Resources 

On August 8, 2017, the Company entered into a purchase agreement (the “LPC Purchase Agreement”) and a registration rights agreement 

with Lincoln Park Capital Fund, LLC (“LPC”), pursuant to which the Company has the right to sell to LPC up to $15,000,000 in shares of the 
Company’s common stock, subject to certain limitations and conditions set forth therein, over the 30-month term of the LPC Purchase Agreement. 
During the year ended December 31, 2018, the Company sold 435,000 shares of common stock to LPC for net proceeds of approximately 
$1,312,000. In total, the Company has sold 495,000 shares of common stock to LPC for net proceeds of approximately $1,602,000.

On April 11, 2018, the Company closed on the April 2018 Offering and Private Placement of its common stock and the April 2018 
Warrants. Net proceeds to the Company from the April 2018 Offering and Private Placement were $4,210,000 after deducting placement agent fees 
and offering expenses paid by the Company.

34

On October 3, 2018, the Company closed on the October 2018 Offering of its Units and Pre-Funded Units. Net proceeds from the October 

2018 Offering were $13,193,000 after deducting underwriting discounts and commissions and offering expenses paid by the Company.

We had cash of $14,879,000 as of December 31, 2018, compared with $3,581,000 as of December 31, 2017. We have reported recurring 
losses from operations since inception and expect that we will continue to have negative cash flows from our operations for the foreseeable future. 
Historically, the Company’s primary source of funding has been the sale of its securities. In the future, we will be dependent on obtaining funding 
from third parties, such as proceeds from the issuance of debt, sale of equity, or strategic opportunities, in order to maintain our operations. There is 
no guarantee that debt, additional equity or other funding will be available to us on acceptable terms, or at all. If we fail to obtain additional funding 
when needed, we would be forced to scale back or terminate our operations or to seek to merge with or to be acquired by another company. We 
believe that our existing cash should be sufficient to fund our operations for at least the next twelve months.

The following table summarizes our cash flows for the periods indicated, in thousands:

Net cash used in operating activities
Net cash used in investing activities
Net cash provided by financing activities

Net cash used in operating activities was $7,520,000 for the year ended December 31, 2018 compared with $9,514,000 for the year ended 

December 31, 2017. The decrease in cash used in operating activities of $1,994,000 was primarily attributable to a decrease in net loss offset by 
adjustments for non-cash expenses, principally acquired in-process research and development expense and deferred tax related to the Company’s 
acquisition of MirImmune in the prior year.

Net Cash Flow from Investing Activities 

Net cash used in investing activities was minimal for the year ended December 31, 2018, compared with $103,000 for the year ended 

December 31, 2017. The decrease in net cash flow from investing activities was primarily related to the purchase of laboratory equipment in the 
prior year offset by cash received in the MirImmune acquisition.

Net Cash Flow from Financing Activities 

Net cash provided by financing activities was $18,823,000 for the year ended December 31, 2018, compared with $292,000 for the year 

ended December 31, 2017. The increase in net cash flow from financing activities was due to proceeds received by the Company from the issuance 
of common stock to LPC, the April 2018 Offering and Private Placement and the October 2018 Offering.

Off-Balance Sheet Arrangements 

In connection with certain license agreements, we are required to indemnify the licensor for certain damages arising in connection with the 
intellectual property rights licensed under the agreement. In addition, we are a party to a number of agreements entered into in the ordinary course of 
business that contain typical provisions that obligate us to indemnify the other parties to such agreements upon the occurrence of certain events. 
These indemnification obligations are considered off-balance sheet arrangements in accordance with ASC Topic 460, “Guarantor’s Accounting and 
Disclosure Requirements for Guarantees, Including Indirect Guarantees of Indebtedness of Others.” To date, we have not encountered material 
costs as a result of such obligations and have not accrued any liabilities related to such obligations in our financial statements. See Note 5 to our 
consolidated financial statements for further discussion of these indemnification agreements.

Report of Independent Registered Public Accounting Firm

Stockholders and Board of Directors
Phio Pharmaceuticals Corp.
Marlborough, Massachusetts

Opinion on the Consolidated Financial Statements 

We have audited the accompanying consolidated balance sheets of Phio Pharmaceuticals Corp. (the “Company”) and subsidiary as of December 31, 
2018 and 2017, the related consolidated statements of operations, convertible preferred stock and stockholders’ equity, and cash flows for the years 
then ended, 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 and subsidiary at December 31, 2018 and 2017, and the 
results of their operations and their cash flows for the years then ended, in conformity with accounting principles generally accepted in the United 
States of America.

Basis for Opinion 

These consolidated financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on the 
Company’s consolidated financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting 
Oversight Board (United States) (“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 consolidated financial statements are free of material misstatement, whether due to error or fraud. The 
Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audits we 
are required to obtain an understanding of internal control over financial reporting but not for the purpose of expressing an opinion on the 
effectiveness of the Company’s internal control over financial reporting. Accordingly, we express no such opinion.

Our audits included performing procedures to assess the risks of material misstatement of the consolidated 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 consolidated 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 consolidated financial statements. We believe that our audits 
provide a reasonable basis for our opinion.

PHIO PHARMACEUTICALS CORP. 
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS 

1. Nature of Operations 

Phio Pharmaceuticals Corp. is a biotechnology company developing the next generation of immuno-oncology therapeutics based on our 

self-delivering RNAi (“sd-rxRNA®”) therapeutic platform. The Company’s efforts are focused on developing sd-rxRNA therapeutic compounds to 
be used in the context of adoptive cell transfer by targeting checkpoints or other gene targets, or to be used in immunotherapy following intra-
tumoral injections. We aim to maximize the power of our sd-rxRNA therapeutic compounds by weaponizing therapeutic immune effector cells to 
attack cancer, and to make tumors more susceptible to such attacks, and ultimately provide patients battling cancers with a powerful new treatment 
option that goes beyond current treatment modalities.

Prior to the Company’s acquisition of MirImmune, Inc. (“MirImmune”), our principal activities consisted of the preclinical and clinical 

development of the Company’s sd-rxRNA compounds and topical immunotherapy agent in the areas of dermatology and ophthalmology. In January 
2018, after a thorough review of its business operations, development programs and financial resources, the Company made a strategic decision to 
focus its efforts solely on immuno-oncology to accelerate growth and support a potential return on investment for its stockholders. In connection 
with this decision, the Company completed all open clinical trials in dermatology and ophthalmology with RXI-109, our first sd-rxRNA clinical 
candidate, and Samcyprone®, and reported out on the results of those clinical studies in 2018. The Company intends to seek a partner and/or out-
licensee for its dermatology program and its ophthalmology program to continue with their development. The Company’s current business strategy 
solely focuses on the development of immuno-oncology therapeutics utilizing our proprietary sd-rxRNA technology.

On November 19, 2018, the Company changed its name from RXi Pharmaceuticals Corporation to Phio Pharmaceuticals Corp., which 

reflects the Company’s transition from a platform company to one that is fully committed to develop groundbreaking immuno-oncology 
therapeutics. 

On January 3, 2018, the Board of Directors of the Company approved a 1-for-10 reverse stock split of the Company’s outstanding common 

stock, which was effected on January 8, 2018. All share and per share amounts in the financial statements have been retroactively adjusted for all 
periods presented to give effect to the reverse stock split, including reclassifying an amount equal to the reduction in par value to additional paid-in 
capital.

2. Summary of Significant Accounting Policies 

Basis of Presentation 

The accompanying financial statements have been prepared in accordance with accounting principles generally accepted in the United 

States of America (“GAAP”).

Principles of Consolidation 

The consolidated financial statements include the accounts of Phio Pharmaceuticals Corp. and its wholly owned subsidiary, MirImmune, 

LLC. All material intercompany accounts have been eliminated in consolidation.

Uses of Estimates in Preparation of Financial Statements 

The preparation of financial statements in accordance 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 financial statements and the reported 
amounts of revenues and expenses during the reporting period. Actual results could differ materially from these estimates.

Restricted Cash 

Restricted cash consists of certificates of deposit held by financial institutions as collateral for the Company’s corporate credit cards.

42

Concentrations of Credit Risk 

Financial instruments that potentially subject the Company to concentrations of credit risk consist principally of cash. The Company 

maintains cash balances in several accounts with one bank, which at times are in excess of federally insured limits. The Company has established 
guidelines related to credit ratings and maturities intended to safeguard principal balances and maintain liquidity. 

Property and Equipment 

Property and equipment are stated at cost and depreciated using the straight-line method based on the estimated useful lives of the related 

assets. The Company provides for depreciation over the assets’ estimated useful lives as follows:

Computer equipment
Machinery & equipment
Furniture & fixtures
Leasehold improvements

3 years
5 years
5 years
5 years

Depreciation and amortization expense for the years ended December 31, 2018 and 2017 was $81,000 and $70,000, respectively.

Derivative Financial Instruments 

The Company follows the provisions of the Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) 

Topic 815, “Derivatives and Hedging” (“ASC 815”). Financial instruments that meet the definition of a derivative are classified as an asset or 
liability and measured at fair value on the issuance date and are revalued on each subsequent balance sheet date. The changes in fair value are 
recognized as current period income or loss. Financial instruments that do not meet the definition of a derivative are classified as equity and 
measured at fair value and recorded as additional paid in capital in stockholders’ equity at the date of issuance. No further adjustments to their 
valuation are made.

Fair Value of Financial Instruments 

The carrying amounts reported in the balance sheet for restricted cash, accounts payable and accrued expenses approximate their fair values 

due to their short-term nature.

Impairment of Long-Lived Assets 

The Company reviews long-lived assets for impairment on an interim basis if an event occurs that might reduce the fair value of such assets 

below their carrying values. An impairment loss would be recognized based on the difference between the carrying value of the asset and its 
estimated fair value, which would be determined based on either discounted future cash flows or other appropriate fair value methods. The 
Company believes no impairment existed as of December 31, 2018. At December 31, 2017, the Company fully impaired its non-marketable 
securities and included impairment expense of $9,000 within total other income/expense on the consolidated statement of operations related to the 
impairment.

43

Research and Development Expenses 

Research and development costs relate to salaries, employee benefits, facility-related expenses, supplies, stock-based compensation related 

to employees and non-employees involved in the Company’s research and development, external services, other operating costs and overhead 
related to its research and development departments, costs to acquire technology licenses and expenses associated with preclinical activities and its 
clinical trials. Research and development expenses are charged to expense as incurred. Payments made by the Company in advance for research and 
development services not yet provided and/or for materials not yet received are recorded as prepaid expenses and expensed when the service has 
been performed or when the goods have been received. Accrued liabilities are recorded related to those expenses for which vendors have not yet 
billed the Company with respect to services provided and/or materials that it has received.

Preclinical and clinical trial expenses relate to estimates of costs incurred and fees connected with clinical trial sites, third-party clinical 

research organizations and other preclinical and clinical related activities and include such items as subject-related fees, laboratory work, 
investigator fees and analysis costs. Costs associated with these expenses are generally payable on the passage of time or when certain milestones 
are achieved. Expense is recorded during the period incurred or in the period in which a milestone is achieved. In order to ensure that the Company 
has adequately provided for preclinical and clinical expenses during the proper period, the Company maintains an accrual to cover these expenses. 
These accruals are assessed on a quarterly basis and are based on such assumptions as expected total cost, the length of the study, timing of certain 
milestones and other information available to us. Actual results may differ from these estimates and could have a material impact on the Company’s 
reported results. The Company’s historical accrual estimates have not been materially different from its actual costs.

Patents and Patent Application Costs 

Although the Company believes that its patents and underlying technology have continuing value, the amount of future benefits to be 

derived from the patents is uncertain. Patent costs are, therefore, expensed as research and development as incurred.

Acquired In-process Research and Development 

Assets purchased in asset acquisition transactions are expensed as in-process research and development unless the assets acquired have an 
alternative future use. Acquired in-process research and development payments are immediately expensed and include upfront payments, as well as 
transaction fees and subsequent milestone payments. Development costs incurred after the acquisition are expensed as incurred.

Stock-based Compensation 

The Company follows the provisions of the FASB ASC Topic 718, “Compensation — Stock Compensation” (“ASC 718”), which requires 

the measurement and recognition of compensation expense for all stock-based payment awards. Stock compensation expense based on the grant 
date fair value estimated in accordance with the provisions of ASC 718 is recognized as an expense over the requisite service period.

44

Income Taxes

The Company recognizes assets or liabilities for the deferred tax consequences of temporary differences between the tax basis of assets or 

liabilities and their reported amounts in the financial statements in accordance with the FASB ASC Topic 740, “Accounting for Income 
Taxes” (“ASC 740”). These temporary differences will result in taxable or deductible amounts in future years when the reported amounts of the 
assets or liabilities are recovered or settled. ASC 740 requires that a valuation allowance be established when management determines that it is more 
likely than not that all or a portion of a deferred asset will not be realized. The Company evaluates the realizability of its net deferred income tax 
assets and valuation allowances as necessary, at least on an annual basis. During this evaluation, the Company reviews its forecasts of income in 
conjunction with other positive and negative evidence surrounding the realizability of its deferred income tax assets to determine if a valuation 
allowance is required. Adjustments to the valuation allowance will increase or decrease the Company’s income tax provision or benefit. The 
recognition and measurement of benefits related to the Company’s tax positions requires significant judgment, as uncertainties often exist with 
respect to new laws, new interpretations of existing laws, and rulings by taxing authorities. Differences between actual results and the Company’s 
assumptions or changes in the Company’s assumptions in future periods are recorded in the period they become known.

Comprehensive Loss 

The Company’s comprehensive loss is equal to its net loss for all periods presented.

Net Loss per Share 

The Company accounts for and discloses net loss per share attributable to common stockholders in accordance with the FASB ASC Topic 

260, “Earnings per Share.” Basic and diluted net loss per common share attributable to common stockholders is computed by dividing net loss 
attributable to common stockholders by the weighted average number of common shares outstanding. Diluted earnings per share is computed by 
dividing the Company’s net earnings by the weighted average number of common shares outstanding and the impact of all dilutive potential 
common shares.

3. Recent Accounting Pronouncements 

In May 2014, the FASB issued Accounting Standards Update (“ASU”) 2014-09, “Revenue from Contracts with Customers (Topic 606).”

ASU 2014-09 states that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that 
reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. On July 9, 2015, the FASB voted to 
delay the effective date of the new revenue standard by one year but to permit entities to choose to adopt the standard as of the original effective 
date. In March 2016, the FASB issued ASU 2016-08, “Revenue from Contracts with Customers (Topic 606) – Principal Versus Agent 
Considerations,” which improves the operability and understandability of the implementation guidance on principal versus agent considerations. In 
April 2016, the FASB issued ASU 2016-10, “Revenue from Contracts with Customers (Topic 606) – Identifying Performance Obligations and 
Licensing,” which clarifies two aspects of the guidance on accounting for revenue contracts with customers: identifying performance obligations and 
the licensing implementation guidance. In May 2016, the FASB issued ASU 2016-12, “Revenue from Contracts with Customers (Topic 606) – 
Narrow Scope Improvements and Practical Expedients,” which addresses collectability assessment, presentation of sales taxes, noncash 
consideration and completed contracts and contract modifications at transition. The amendments in these ASUs do not change the core principles for 
those areas. This standard became effective for annual reporting periods beginning after December 15, 2017, including interim periods within that 
reporting period. Early adoption is not permitted. The Company adopted this ASU in the first quarter of 2018. Since the Company has no significant 
revenue, this ASU had no immediate impact on its consolidated financial statements.

In February 2016, the FASB issued ASU 2016-02, “Leases (Topic 842),” (“Topic 842”) which requires companies that are lessees to 

recognize a right-of-use asset and lease liability for most leases that do not meet the definition of a short-term lease. For income statement purposes, 
leases will continue to be classified as either operating or financing. This standard will result in extensive qualitative and quantitative disclosure 
changes. In July 2018, the FASB issued ASU 2018-10, “Codification Improvements to Topic 842, Leases,” which affects narrow aspects of the 
guidance issued in the amendments in ASU 2016-02, “Leases.” The FASB further issued ASU 2018-11, “Leases (Topic 842): Targeted 
Improvements,” in July 2018, which provides entities with an additional (and optional) transition method to adopt the new leases standard. This 
standard will be effective for annual reporting periods beginning after December 15, 2018, including interim periods within that reporting period.

45

The Company will adopt Topic 842 on January 1, 2019, using the modified retrospective approach as applied to leases existing as of or 
entered into after the adoption date. Topic 842 provides a number of optional practical expedients and accounting policy elections. The Company 
has elected the package of practical expedients to not reassess whether any expired or existing contracts are or contain leases, lease classification of 
existing or expiring leases and indirect costs for existing or expired leases. The Company has also elected the practical expedient to not separate 
lease and non-lease components and instead account for each separate lease component and non-lease components associated with that lease as a 
single lease component. Upon adoption of Topic 842, the Company expects that the standard will have a material effect on its financial statements. 
The Company continues to assess all of the effects of the impact of the adoption and expects that the most significant effects will primarily relate to 
the recognition of a right of use asset and corresponding lease liability on the balance sheet on the date of adoption, currently estimated at $30,000, 
and providing significant new disclosures around leasing activities. The Company does not expect the adoption of the new standard to have a 
significant impact on its consolidated statements of operations or cash flows.

In June 2018, the FASB issued ASU 2018-07, “Compensation – Stock Compensation (Topic 718) – Improvements to Nonemployee Share-

Based Payment Accounting,” which expands the scope of ASC 718 to include share-based payment transactions for acquiring goods and services 
from non-employees. The amendment specifies that ASC 718 applies to all share-based payment transactions in which a grantor acquires goods or 
services to be used or consumed in a grantor’s own operations by issuing share-based payment awards. This standard will be effective for annual 
reporting periods beginning after December 15, 2018, including interim periods within that reporting period. Early adoption is permitted, but no 
earlier than an entity’s adoption date of Topic 606. The Company early adopted this ASU in the second quarter of 2018. The ASU had no material 
impact on the Company’s consolidated financial statements.

In August 2018, the Securities and Exchange Commission issued Release No. 33-10532 that amends and clarifies certain financial 

reporting requirements. The principal change to the Company’s financial reporting will be the inclusion of the annual disclosure requirement of 
changes in stockholders’ equity in Rule 3-04 of Regulation S-X to interim periods. The Company will adopt this new rule beginning with our 
financial reporting for the quarter ended March 31, 2019. Upon adoption, the Company will include the consolidated statements of stockholders’ 
equity with each quarterly filing on Form 10-Q.

The Company acquires assets under development and enters into research and development arrangements with third parties that often 

require milestone and royalty payments based on the progress of the asset through development stages. Milestone payments may be required, for 
example, upon approval of the product for marketing by a regulatory agency. In certain agreements, the Company is required to make royalty 
payments based upon a percentage of the sales of the products licensed pursuant to such agreements. Because of the contingent nature of these 
payments, they are not included in the table of contractual obligations shown below (see also Note 11).

These arrangements may be material individually, and in the unlikely event that milestones for multiple products covered by these 

arrangements were reached in the same period, the aggregate charge to expense could be material to the results of operations. In addition, these 
arrangements often give the Company the discretion to unilaterally terminate development of the product, which would allow the Company to avoid 
making the contingent payments; however, the Company is unlikely to cease development if the compound successfully achieves clinical testing 
objectives.

Operating Leases 

The Company leases office and laboratory space for its corporate headquarters and primary research facility in Marlborough, 
Massachusetts. The lease for the office and lab space will expire on March 31, 2019. Average monthly rental expense is approximately $10,300, 
which includes the Company’s pro rata share of annual real estate taxes and operating expenses. The Company recognizes rental expense on its 
office space on a straight-line basis over the lease term. Differences between the straight-line rent expense and rent payments are classified as 
deferred rent.

Total rent expense under the Company’s operating lease was approximately $120,000 and $115,000 for the years ended December 31, 

2018 and 2017, respectively.

At December 31, 2018, the Company’s future minimum payments required under operating leases are as follows, in thousands:

The Company applies the disclosure provisions of the FASB ASC Topic 460, “Guarantor’s Accounting and Disclosure Requirements for 

Guarantees, Including Indirect Guarantees of Indebtedness of Others” (“ASC 460”), to its agreements that contain guarantee or indemnification 
clauses. The Company provides: (i) indemnifications of varying scope and size to certain investors and other parties for certain losses suffered or 
incurred by the indemnified party in connection with various types of third-party claims; and (ii) indemnifications of varying scope and size to 
officers and directors against third-party claims arising from the services they provide to us. These indemnifications give rise only to the disclosure 
provisions of ASC 460. To date, the Company has not incurred costs as a result of these obligations and does not expect to incur material costs in 
the future. Accordingly, the Company has not accrued any liabilities in its consolidated financial statements related to these indemnifications.

6. MirImmune Inc. Acquisition

On January 6, 2017, the Company entered into a Stock Purchase Agreement (the “Stock Purchase Agreement”) and completed its 

acquisition of MirImmune. Pursuant to the Stock Purchase Agreement, the Company acquired all of the issued and outstanding shares of capital 
stock of MirImmune for an aggregate of 275,036 shares of common stock of the Company and an aggregate of 1,118,224 shares of Series C 
Convertible Preferred Stock of the Company (the “Series C Convertible Preferred Stock”).

The acquisition of MirImmune was assessed under the FASB ASC Topic 805, “Business Combinations” (“ASC 805”). Under ASC 805, 

the Company determined that the acquired assets did not constitute a business and that the transaction would be accounted for as an asset 
acquisition. Under ASC 805, the assets acquired were considered to have no alternative future uses, as determining the future economic benefit of 
the acquired assets at the date of acquisition was highly uncertain. The fair value of the assets was determined using the quoted market price of the 
Company’s common stock on January 6, 2017, the date of the acquisition, and was fully expensed as in-process research and development.

Additionally, the Company assessed the MirImmune acquisition under ASC Topic 740, “Income Taxes” (“ASC 740”). The acquisition 
resulted in an income tax benefit of $1,621,000 and a corresponding increase to acquired in-process research and development expense resulting 
from the reduction in the Company’s valuation allowance due to the deferred tax liability created as a result of the book and tax basis difference 
during the year ended December 31, 2017.

During the year ended December 31, 2017, the Company recorded $4,696,000 in in-process research and development expense related to 
the fair value of consideration given, which includes transaction costs, liabilities assumed and cancellation of notes receivable, and the deferred tax 
impact of the MirImmune acquisition.

The Company was restricted from converting any of the Series C Convertible Preferred Stock into common stock to the extent that such 
conversion was not approved by the Company’s stockholders in accordance with the stockholder approval requirements of Nasdaq Marketplace 
Rule 5635. On June 9, 2017, with the approval of the Company’s stockholders in accordance with the Nasdaq stockholder approval requirements, 
every ten shares of the Series C Convertible Preferred Stock outstanding were automatically converted into one share of common stock, such that 
there were no shares of Series C Convertible Preferred Stock issued or outstanding after the conversion.

Under the terms of the Stock Purchase Agreement, if certain development or commercial milestones are achieved within two years, the 

Company will be required to either (i) issue a number of shares of common stock (the “Milestone Shares”) equal to the sum of 251,909 shares of 
common stock, plus an additional number of shares of common stock equal to 13% of the common stock issued upon exercise of any warrants 
issued under the Company’s underwritten public offering completed in December 2016, but only to the extent that such warrants have been 
exercised prior to the milestone being achieved or (ii) pay the equivalent value of the Milestone Shares in cash.

The Company assessed the Milestone Shares under the FASB ASC Topic 480, “Distinguishing Liabilities from Equity” (“ASC 480”). The 

Company determined that liability accounting would be required for the Milestone Shares under ASC 480. The Company will record a liability 
related to the Milestone Shares if and when the milestones are achieved and the consideration becomes payable. At that time, the Company will 
record the cost of the Milestone Shares as in-process research and development expense. No milestones under the Stock Purchase Agreement have 
been met as of December 31, 2018 or 2017. Additionally, on January 6, 2019, the Company had not met the development or commercial milestones 
as set forth in the Stock Purchase Agreement and is no longer required to issue the Milestone Shares or pay the equivalent value of Milestone Shares 
in cash.

7. Stockholders’ Equity 

Lincoln Park Capital Fund, LLC — On August 8, 2017, the Company entered into a purchase agreement (the “Purchase Agreement”) and 

a registration rights agreement with Lincoln Park Capital, LLC (“LPC”), pursuant to which the Company has the right to sell to LPC shares of the 
Company’s common stock, subject to certain limitations and conditions set forth in the 2017 Purchase Agreement.

As a commitment fee for entering into the Purchase Agreement, the Company issued 45,000 shares of the Company’s common stock to 
LPC at a value per share of $5.80, which was recorded as a cost of capital. During the year ended December 31, 2018, the Company sold 435,000 
shares of common stock to LPC for net proceeds of approximately $1,312,000. During the year ended December 31, 2017, the Company sold 
60,000 shares of common stock to LPC for net proceeds of approximately $290,000.

April 2018 Registered Direct Offering and Private Placement — On April 11, 2018, the Company closed a registered direct offering of 
1,510,604 shares of the Company’s common stock at a purchase price of $3.15 per share (the “April 2018 Offering”) pursuant to the Securities 
Purchase Agreement dated as of April 9, 2018. In a concurrent private placement, the Company sold warrants (the “April 2018 Warrants”) to 
purchase a total of 1,132,953 shares of common stock at a purchase price of $0.125 per underlying warrant share and with an exercise price of $3.15 
per share (the “Private Placement”). Net proceeds to the Company from the April 2018 Offering and Private Placement were $4,210,000 after 
deducting placement agent fees and offering expenses paid by the Company. In connection with the April 2018 Offering and Private Placement, the 
Company issued warrants to purchase a total of 75,530 shares of common stock with an exercise price of $4.0546 per share to the placement agent, 
H.C. Wainwright& Co., LLC (“HCW”) (the “Placement Agent Warrants”)

The Company assessed the April 2018 Warrants and Placement Agent Warrants under the FASB ASC Topic 480, “Distinguishing 
Liabilities from Equity” (“ASC 480”) and determined that the April 2018 Warrants and Placement Agent Warrants were outside the scope of ASC 
480. The Company next assessed the April 2018 Warrants and Placement Agent Warrants under the FASB ASC Topic 815, “Derivatives and 
Hedging” (“ASC 815”). Under the related guidance, a reporting entity shall not consider a contract to be a derivative instrument if the contract is 
both (1) indexed to the entity’s own stock and (2) classified in stockholders’ equity. The Company determined that the April 2018 Warrants and 
Placement Agent Warrants were indexed to the Company’s stock, as the agreements do not contain any exercise contingencies and the settlement 
amount equals the difference between the fair value of the Company’s common stock price and the strike price. The Company also assessed the 
classification in stockholders’ equity and determined the April 2018 Warrants and Placement Agent Warrants met all of the criteria for classification 
as equity under ASC 815. Based on this analysis, the Company determined that the April 2018 Warrants and Placement Agent Warrants would be 
classified in stockholders’ equity.

October 2018 Underwritten Public Offering — On October 3, 2018, the Company closed an underwritten public offering (the “October 

2018 Offering”) of (i) 3,725,714 units (the “Units”), at a public offering price of $0.70 per Unit, with each Unit consisting of one share of common 
stock and one warrant (the “October 2018 Warrants”) to purchase one share of common stock and (ii) 17,702,858 pre-funded units (the “Pre-
Funded Units”), at a public offering price of $0.69 per Pre-Funded Unit, with each Pre-Funded Unit consisting of one pre-funded warrant (the 
“Pre-Funded Warrants”) to purchase one share of common stock and one October 2018 Warrant. The October 2018 Warrants included in the 
Units and Pre-Funded Units are immediately exercisable at a price of $0.70 per share and expire seven years from the date of issuance. The Pre-
Funded Warrants included in the Pre-Funded Units are immediately exercisable at a price per share of $0.01 and do not expire. Net proceeds from 
the October 2018 Offering were $13,193,000 after deducting underwriting discounts and commissions and offering expenses paid by the Company. 
Additionally, pursuant to the October 2018 Offering, the Company issued warrants to purchase up to 1,607,143 shares of common stock at an 
exercise price of $0.875 per share to the underwriter, HCW (the “Underwriter Warrants”).

The Company assessed the October 2018 Warrants and Underwriter Warrants under the FASB ASC Topic 480, “Distinguishing Liabilities 

from Equity” (“ASC 480”) and determined that the October 2018 Warrants and Underwriter Warrants were outside the scope of ASC 480. The 
Company next assessed the October 2018 Warrants and Underwriter Warrants under the FASB ASC Topic 815, “Derivatives and Hedging” (“ASC 
815”). Under the related guidance, a reporting entity shall not consider a contract to be a derivative instrument if the contract is both (1) indexed to 
the entity’s own stock and (2) classified in stockholders’ equity. The Company determined that the October 2018 Warrants and Underwriter 
Warrants were indexed to the Company’s stock, as the agreements do not contain any exercise contingencies and the settlement amount equals the 
difference between the fair value of the Company’s common stock price and the strike price. The Company also assessed the classification in 
stockholders’ equity and determined the October 2018 Warrants and Underwriter Warrants met all of the criteria for classification as equity under 
ASC 815. Based on this analysis, the Company determined that the October 2018 Warrants and Underwriter Warrants would be classified in 
stockholders’ equity.

On January 23, 2012, the Company’s Board of Directors and sole stockholder adopted the Phio Pharmaceuticals Corp. 2012 Long-Term 
Incentive Plan (the “2012 Incentive Plan”). Under the 2012 Incentive Plan, the Company may grant incentive stock options, nonqualified stock 
options, cash awards, stock appreciation rights, restricted and unrestricted stock and stock unit awards and other stock-based awards. The 
Company’s Board of Directors currently acts as the administrator of the Company’s 2012 Incentive Plan. The administrator has the power to select 
participants from among the key employees, directors and consultants of and advisors to the Company, establish the terms, conditions and vesting 
schedule, if applicable, of each award and to accelerate vesting or exercisability of any award.

50

As of December 31, 2018, an aggregate of 750,000 shares of common stock were reserved for issuance under the Company’s 2012 
Incentive Plan, including 141,677 shares subject to outstanding common stock options and 137,500 shares subject to unvested restricted stock units 
(“RSUs”) granted under the 2012 Incentive Plan and 470,803 shares available for future grants. Stock options and RSUs granted by the Company to 
employees vest annually over 4 years after the grant date and, in the instance of stock options, expire within ten years of issuance.

Stock Options

The Company uses the Black-Scholes option-pricing model to determine the fair value of all its option grants. For valuing options granted 

during the years ended December 31, 2018 and 2017, the following assumptions were used:

Risk-free interest rate

The weighted-average fair value of options granted during the years ended December 31, 2018 and 2017 was $1.75 and $4.90 per share, 

respectively.

The risk-free interest rate used for each grant was based upon the yield on zero-coupon U.S. Treasury securities with a term similar to the 
expected life of the related option. The Company’s expected stock price volatility assumption is based upon the Company’s own implied volatility. 
The expected life assumption for option grants is based upon the simplified method provided for under ASC 718. The dividend yield assumption is 
based upon the fact that the Company has never paid cash dividends and presently has no intention of paying cash dividends.

Stock-based compensation expense related to stock options for the year ended December 31, 2018 and 2017 was $112,000 and $314,000, 

respectively.

There is no income tax benefit as the Company is currently operating at a loss and an actual income tax benefit may not be realized.

As of December 31, 2018, the compensation expense for all unvested stock options in the amount of approximately $200,000 will be 

recognized in the Company’s results of operations over a weighted average period of 3.04 years.

Restricted Stock Units

In addition to stock options to purchase shares of common stock, the Company may also grant RSUs. RSUs are generally subject to graded 

vesting and the satisfaction of service requirements, similar to our stock options. Upon vesting, each outstanding RSU will be exchanged for one 
share of the Company’s common stock. The fair value of the RSUs awarded are based on the Company’s closing stock price at the grant date and 
are expensed over the requisite service period.

Restricted Stock

On August 31, 2018, Geert Cauwenbergh, Dr. Med. Sc., the Company’s former Chief Executive Officer, elected the right to receive, in lieu 

of cash, for the period from September 15, 2018 to December 31, 2018, up to 50% of his base salary and cash bonuses, if any, (collectively, the 
“Compensation”) payable in the form of unvested, restricted shares of the Company’s common stock. Such restricted shares will be received in the 
form of a series of grants made on each Company payroll date in lieu of cash payment of the Compensation and shall vest in full on January 1, 2019, 
subject to his continued employment through such date. On December 19, 2018, the Company and Dr. Cauwenbergh agreed to extend the applicable 
period of the election through February 28, 2019 and that all restricted stock issued during the election period will vest on March 1, 2019.

The fair value of the restricted stock is based on the Company’s closing stock price on the date of grant and is expensed over the vesting 

period. For the year ended December 31, 2018, the Company granted 203,302 restricted shares of the Company’s common stock in lieu of 
Compensation to Dr. Cauwenbergh. Stock-based compensation expense related to the restricted shares was $118,000 for the year ended December

The Company’s acquisition of MirImmune resulted in an income tax benefit of $1,621,000 in 2017 and a corresponding increase to 

acquired in-process research and development expense resulting from the reduction in the Company’s valuation allowance due to the deferred tax 
liability created as a result of the book and tax basis difference.

The Company’s deferred tax assets at December 31, 2018 and 2017 consisted primarily of its net operating loss carryforwards, deferred 
compensation, tax credit carryforwards, intangible assets capitalized for federal income tax purposes and certain accruals that for tax purposes are 
not deductible until future payment is made. The valuation allowance increased $2,194,000 and decreased $4,621,000 for the years ended 
December 31, 2018 and 2017, respectively, and is primarily attributable to an increase in net operating losses and tax credits.

On December 22, 2017, the President of the United States signed into law the Tax Cuts and Jobs Act tax reform legislation. This legislation 

makes significant changes in U.S. tax law including a reduction in the corporate tax rates, changes to net operating loss carryforwards and 
carrybacks, and a repeal of the corporate alternative minimum tax. The legislation reduced the U.S. corporate tax rate from the current rate of 34% 
to 21%. As a result of the enacted law, the Company was required to revalue deferred tax assets and liabilities at the enacted rate. This revaluation 
resulted in a decrease to the Company’s net deferred tax assets of approximately $8,800,000 and a corresponding reduction of the same amount in 
the valuation allowance against these deferred tax assets in the fourth quarter of 2017. The Company concluded the tax accounting consideration 
associated with the Tax Cuts and Jobs Act and no material adjustments were recorded in the year ended December 31, 2018.  

54

The Company has incurred net operating losses since inception. At December 31, 2018, the Company had federal and state net operating 

loss carryforwards of approximately $64,000,000 and $56,000,000, respectively, which are available to reduce future taxable income through 2038. 
In addition, the Company has federal and state research credits of $1,116,000 and $558,000, respectively, to offset future tax expense through 2038. 
Based on an assessment of all available evidence including, but not limited to the Company’s limited operating history in its core business and lack 
of profitability, uncertainties of the commercial viability of its technology, the impact of government regulation and healthcare reform initiatives, 
and other risks normally associated with biotechnology companies, the Company has concluded that it is more likely than not that these net 
operating loss carryforwards and credits will not be realized and, as a result, a full deferred income tax valuation allowance has been recorded 
against these assets.

Under the provisions of the Internal Revenue Code, certain substantial changes in the Company’s ownership may result in a limitation on 
the amount of net operating loss carryforwards and research and development credit carryforwards which could be utilized annually to offset future 
taxable income and taxes payable. The Company does not believe any substantial changes in ownership have occurred, however a detailed analysis 
would need to be conducted in order to be certain.

The Company files income tax returns in the United States, Massachusetts and New Jersey. The Company is subject to tax examinations 

for federal and state purposes for tax years 2012 through 2018. The Company has not recorded any uncertain tax positions as of December 31, 2018 
or 2017. The Company does not believe there will be any material changes in its unrecognized tax positions over the next 12 months. The Company 
has not incurred any interest or penalties. In the event that the Company is assessed interest or penalties at some point in the future, they will be 
classified in the financial statements as general and administrative expenses.

11. License Agreements 

As part of its business, the Company enters into licensing agreements with third parties that often require milestone and royalty payments 
based on the progress of the asset through development stages. Milestone payments may be required, for example, upon approval of the product for 
marketing by a regulatory agency. In certain agreements, the Company is required to make royalty payments based upon a percentage of the sales of 
the products licensed pursuant to such agreements.

The expenditures required under these arrangements may be material individually in the event that the Company develops product 
candidates covered by the intellectual property licensed under any such arrangement, and in the unlikely event that milestones for multiple products 
covered by these arrangements were reached in the same period, the aggregate charge to expense could be material to the results of operations. In 
addition, these arrangements often give the Company discretion to unilaterally terminate development of the product, which would allow the 
Company to avoid making the contingent payments; however, the Company is unlikely to cease development if the compound successfully achieves 
clinical testing objectives.

Advirna LLC. We have entered into an agreement with Advirna LLC (“Advirna”), pursuant to which Advirna assigned to us its existing 

patent and technology rights related to the sd-rxRNA technology. In exchange, the Company is obligated to pay Advirna an annual maintenance fee 
and paid a milestone payment upon the issuance of the first patent with valid claims covering the assigned technology in 2014. Additionally, we will 
be required to pay a 1% royalty to Advirna on any licensing revenue received by us with respect to future licensing of the assigned Advirna patent 
and technology rights. To date, royalties owed to Advirna under the agreement have been minimal. We also granted back to Advirna a license under 
the assigned patent and technology rights for fields of use outside human therapeutics.

55

Our rights under the Advirna agreement will expire upon the later of: (i) the expiration of the last-to-expire of the “patent rights” (as 
defined therein) included in the Advirna agreement; or (ii) the abandonment of the last-to-be abandoned of such patents, unless earlier terminated in 
accordance with the provisions of the agreement.

Hapten Pharmaceuticals, LLC. We have entered into an Assignment and License Agreement (the “Assignment and License Agreement”) 
with Hapten Pharmaceuticals, LLC (“Hapten”) under which Hapten agreed to sell and assign to us certain patent rights and related assets and rights, 
including an investigational new drug application and clinical data, for Hapten’s Samcyprone products for therapeutic and prophylactic use. Under 
the Assignment and License Agreement, Hapten will be entitled to receive: (i) future milestone payments tied to the achievement of certain clinical 
and commercial objectives (all of which payments may be made at our option in cash or through the issuance of common stock); and (ii) escalating 
royalties based on product sales by us and any sublicensees. To date, no milestones have been met and no royalties have been earned under the 
Assignment and License Agreement with Hapten.

We have certain customary diligence obligations under the Assignment and License Agreement requiring us to use commercially 
reasonable efforts to develop and commercialize one or more products covered by the Assignment and License Agreement, which obligations, if not 
performed, could result in rights assigned or licensed to us reverting back to Hapten.

12. Subsequent Events 

Subsequent to the balance sheet date, the Company received proceeds of approximately $32,100 from the exercise of Pre-Funded Warrants 

for a total of 3,214,286 shares of common stock.

On January 22, 2019, the Company executed a First Amendment (the “First Amendment”) to the lease dated December 17, 2013 with 257 

Simarano LLC (the “Lease”). The Lease covers approximately 7,581 of premises used by the Company for office and laboratory space located at 
257 Simarano Drive, Marlborough, Massachusetts. The First Amendment extended the Lease term commencing on April 1, 2019 for five years (the 
“Extension Term”). The base rent for the premises during the first year of the Extension Term is $124,864.78 per annum, payable monthly. Each 
year thereafter, the base rent shall increase by approximately 3% over the base rent from the prior year. With six months’ advance notice, either 
party may terminate the lease on March 31, 2021, paying the non-terminating party six months’ rent as a penalty or on March 31, 2022, paying the 
non-terminating party three months’ rent as a penalty. The Company will adopt Topic 842 on January 1, 2019 and expects that the Extension Term 
will increase the right of use asset and corresponding lease liability to be recognized on the balance sheet to a current estimation of approximately 
$600,000. The Company is continuing to assess all the effects of the impact of the adoption.

ITEM 9A. CONTROLS AND PROCEDURES 

Evaluation of Disclosure Controls and Procedures 

Our management, with the participation of our Chief Executive Officer, evaluated the effectiveness of disclosure controls and procedures 
(as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act) as of the end of the period covered by this report to ensure that information 
that we are required to disclose in reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported within the 
time periods specified in SEC rules and forms.

Our disclosure controls and procedures are designed to provide reasonable assurance of achieving their objectives. We believe that a 

control system, no matter how well designed and operated, cannot provide absolute assurance that the objectives of the control system are met, and 
no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any, within a company have been detected. 
Based on the evaluation of our disclosure controls and procedures as of the end of the period covered by this report, management concluded that our 
disclosure controls and procedures were effective as of such date.

Remediation of Previous Material Weakness in Internal Control Over Financial Reporting

In connection with the preparation of our consolidated financial statements as of and for the year ended December 31, 2017, we identified a 
material  weakness  in  our  internal  control  over  financial  reporting  related  to  our  controls  over  accounting  for  income  taxes.  During  the  year 
ended December  31,  2018,  the  Company  has  executed  on  its  remediation  plan  for  this  material  weakness  and  the  material  weakness  has  been 
remediated.

Management’s Annual Report on Internal Control Over Financial Reporting 

Our management is responsible for establishing and maintaining adequate 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.

There are inherent limitations in the effectiveness of any system of internal control, including the possibility of human error and the 
circumvention or overriding of controls. Accordingly, even effective internal controls can provide only reasonable assurances with respect to 
financial statement preparation. Further, because of changes in conditions, the effectiveness of internal control may vary over time.

Our management assessed the effectiveness of our internal control over financial reporting as of December 31, 2018. In making this 

assessment, management used the criteria set forth in Internal Control – Integrated Framework issued by the Committee of Sponsoring 
Organizations of the Treadway Commission (2013 framework). Based on this assessment, management concluded that, as of December 31, 2018, 
our internal control over financial reporting was effective.

Attestation Report of the Registered Public Accounting Firm 

This Annual Report on Form 10-K provides only management’s report. As a smaller reporting company, we are not required to provide an 

attestation report by our independent registered public accounting firm regarding internal control over financial reporting.

Changes in Internal Control Over Financial Reporting 

During 2018, management implemented its remediation plan to address the control deficiency that led to the material weakness in internal 
control over financial reporting related to our controls over accounting for income taxes for the fiscal year ended December 31, 2017. As part of the 
remediation plan management executed on (i) implementing the increased involvement on a quarterly basis with our third-party tax accountants 
dedicated to determining the appropriate accounting for material and complex tax transactions in a timely manner, (ii) reviewing our tax accounting 
process to identify and implement enhanced tax accounting process and related internal control procedures and (iii) established additional training 
and education programs for financial personnel responsible for income tax accounting. There were no other changes in our internal control over 
financial reporting during the quarter ended December 31, 2018 that have materially affected, or are reasonably likely to materially affect, our 
internal control over financial reporting.

Board Leadership Structure and Role in Risk Oversight 

The positions of Chairman of the Board of Directors (the “Board”) and Chief Executive Officer are separated, which allows our Chief 

Executive Officer to focus on our day-to-day business, while allowing the Chairman of the Board to lead the Board in its fundamental role of 
providing advice to and independent oversight of management. Our Board recognizes the time, effort and energy that the Chief Executive Officer is 
required to devote to his position in the current business environment, as well as the commitment required to serve as our Chairman. Our Board also 
believes that this structure ensures a greater role for the independent directors in the oversight of our Company and active participation of the 
independent directors in setting agendas and establishing priorities and procedures for the work of our Board. Our Board believes its administration 
of its risk oversight function has not affected its leadership structure.

While our Bylaws do not require that our Chairman and Chief Executive Officer positions be separate, our Board believes that having 

separate positions and having an independent outside director serve as Chairman is the appropriate leadership structure for us at this time and 
demonstrates our commitment to good corporate governance. Our separated Chairman and Chief Executive Officer positions are augmented by our 
independent Board committees that provide appropriate oversight in the areas described below. At executive sessions of independent directors, these 
directors speak candidly on any matter of interest, which may be with or without the Chief Executive Officer present. The independent directors 
meet separately in executive session on at least an annual basis to discuss matters relating to the Company and the Board, without members of the 
management team present. We believe this structure provides consistent and effective oversight of our management and the Company.

The Board has overall responsibility for the oversight of the Company’s risk management process, which is designed to support the 
achievement of organizational objectives, including strategic objectives, to improve long-term organizational performance and enhance stockholder 
value. Risk management includes not only understanding company-specific risks and the steps management implements to manage those risks, but 
also what level of risk is acceptable and appropriate for the Company. Management is responsible for establishing our business strategy, identifying 
and assessing the related risks and implementing appropriate risk management practices. The Board periodically reviews our business strategy and 
management’s assessment of the related risk, and discusses with management the appropriate level of risk for the Company. The Board also 
delegates oversight to Board committees to oversee selected elements of risk as set forth below.

Board Committees

Audit Committee

The Audit Committee is composed of Messrs. Brownlie (Chairman) and Dorman and Dr. Freeman. The Audit Committee selects the 

Company’s independent registered public accounting firm, approves its compensation, oversees and evaluates the performance of the independent 
registered public accounting firm, oversees the accounting and financial reporting policies and internal control systems of the Company, reviews the 
Company’s interim and annual financial statements, independent registered public accounting firm reports and management letters and performs 
other duties, as specified in the Audit Committee Charter. All members of the Audit Committee satisfy the current independence and experience 
requirements of Rule 10A-3 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”) and the current Nasdaq independence 
standards, and the Board has determined that Mr. Brownlie is an “audit committee financial expert,” as the Securities and Exchange Commission 
(the “SEC”) has defined that term in Item 407 of Regulation S-K.

Compensation Committee 

The Compensation Committee is composed of Messrs. Bitterman (Chairman) and Brownlie and Dr. Lockshin. The Compensation 

Committee determines compensation levels for the Company’s executive officers and directors, oversees administration of the Company’s equity 
compensation plans and performs other duties regarding compensation for employees and consultants as the Board may delegate from time to time. 
Our Chief Executive Officer makes recommendations to the Compensation Committee regarding the corporate and individual performance goals 
and objectives relevant to executive compensation and executives’ performance in light of such goals and objectives and recommends other 
executives’ compensation levels to the Compensation Committee based on such evaluations. The Compensation Committee considers these 
recommendations and then makes an independent decision regarding officer compensation levels and awards. All members of the Compensation 
Committee satisfy the current Nasdaq independence standards, and each member of the Committee qualifies as an “outside director” and “non-
employee director” as defined by Section 162(m) of the Code and Rule 16b-3 of the Exchange Act, respectively.

Nominating and Corporate Governance Committee 

The Nominating and Corporate Governance Committee is comprised of Drs. Lockshin (Chairman) and Freeman and Messr. Dorman. The 

Nominating and Governance Committee reviews potential director nominees, recommends nominees to the Board, oversees the Company’s 
corporate governance principles and develops and implements policies and processes regarding corporate governance matters. Drs. Lockshin and 
Freeman and Messr. Dorman satisfy the current Nasdaq independence standards.

A copy of the Company’s Audit, Compensation and Nominating and Corporate Governance Committee charters are available on the 

Company’s website at www.phiopharma.com.

Section 16(a) Beneficial Ownership Reporting Compliance 

Section 16(a) of the Exchange Act requires our “officers” (as defined in Rule 16a-1(f) under the Exchange Act) and directors, and persons 

who own more than 10% of a registered class of our equity securities to file reports of beneficial ownership and changes in beneficial ownership 
with the SEC. Officers, directors and greater-than-10% stockholders (the “Reporting Persons”) are required by SEC regulations to furnish us with 
copies of all reports filed under Section 16(a). Based solely on our review of copies of these reports and representations of such Reporting Persons, 
we believe that during fiscal year 2018, all Reporting Persons satisfied such applicable SEC filing requirements.

Code of Business Conduct and Ethics 

We have adopted a Code of Business Conduct and Ethics that applies to all our directors, officers and employees, including our principal 

executive officer, principal financial officer, principal accounting officer or controller, or persons performing similar functions. Our Code of 
Business Conduct and Ethics, as well as other corporate governance materials, is located on our website at www.phiopharma.com. We intend to 
disclose future amendments to certain provisions of the Code of Business Conduct and Ethics, and waiver of the Code of Business Conduct and 
Ethics granted to executive officers and directors, on the website within four business days following the date of the amendment or waiver.

subject to the Company’s stockholders’ approving a sufficient increase of shares of common stock that may be offered pursuant to the Company’s 
2012 Long Term Incentive Plan at the Company’s next Annual Meeting. Such restricted stock units will vest in equal annual installments over four 
years beginning with the effective date of Dr. Dispersyn’s appointment as CEO and will become fully vested and exercisable on March 1, 2023. 
Otherwise, Dr. Dispersyn’s April 24, 2017 employment agreement with the Company remains in full force and effect.

Dr. Dispersyn’s employment agreement provides that, upon termination of Dr. Dispersyn’s employment without “cause” (as defined 

therein) by us or by Dr. Dispersyn for “good reason” (as defined therein), he will be entitled to payment of: (1) any accrued but unpaid salary and

of termination; (y) accelerated vesting of any unvested stock options held by him as to 50% of the unvested option shares or the portion of the 
unvested option shares that would have vested over the following twenty-four months, whichever is greater; and (z) continued participation, at our 
expense, during the twelve-month severance period in our sponsored group medical and dental plans.

underlying common stock on the date of grant. The option was to vest in equal monthly installments over four years beginning on February 6, 2017, 
provided, in each case, that Dr. Eliseev remained in our continuous employ through such vesting date.

The employment agreement provided that if we were to terminate Dr. Eliseev’s employment without “cause” (as defined in the 

employment agreement), he would be entitled to payment of (1) any accrued but unpaid salary and unused vacation as of the date of his termination; 
(2) six months of salary from the date of terminations; and (3) continued participation, at our expense, during the applicable six-month severance 
period in our sponsored group medical and dental plans. Effective September 15, 2017, Dr. Eliseev’s employment with the Company ended and was 
treated as a termination without “cause”. Dr. Eliseev received severance benefits totaling $150,000 consistent with and subject to the conditions set 
forth in the employment agreement.

compensation is set forth above in the Summary Compensation Table.

Each non-employee director is entitled to receive an annual cash retainer of $25,000. The chairs of our Board and Audit Committee are 

entitled to receive an additional annual cash retainer of $10,000 and the chair of the Nominating and Corporate Governance Committee is entitled to 
receive an additional annual cash retainer of $5,000.

66

Each non-employee director is entitled to receive an annual restricted stock unit award for 10,000 shares of the Company’s common stock, 

vesting annually over one year.

Non-employee directors are also reimbursed for their travel and reasonable out-of-pocket expenses incurred in connection with attending 

Board and committee meetings and in attending continuing education seminars, to the extent that attendance is required by the Board or the 
committee(s) on which that director serves.

The Compensation Committee and the Board reassess the appropriate level of equity compensation for non-employee directors on an 

annual basis. Future equity compensation payments will be determined on a year-by-year basis for the foreseeable future due to the volatility of the 
Company’s stock price.

Beneficial Ownership 

Based on information available to us and filings with the Securities and Exchange Commission (“SEC”), the following table sets forth 
certain information regarding the beneficial ownership (as defined by Rule 13d-3 under the Exchange Act) of our outstanding common stock for 
(i) each of our directors, (ii) each of our “named executive officers,” as defined in the Executive Compensation section above, (iii) all of our 
directors and executive officers as a group and (iv) persons known to us to beneficially own more than 5% of our outstanding common stock. The 
following information is presented as of March 1, 2019 or such other date as may be reflected below.

Beneficial ownership and percentage ownership are determined in accordance with the rules of the SEC and include voting or investment 
power with respect to shares of stock. This information does not necessarily indicate beneficial ownership for any other purpose. Under these rules, 
shares of common stock issuable under stock options or warrants that are exercisable within 60 days of March 1, 2019 are deemed outstanding for 
the purpose of computing the percentage ownership of the person holding the options or warrants, but are not deemed outstanding for the purpose of 
computing the percentage ownership of any other person.

Unless otherwise indicated and subject to applicable community property laws, to our knowledge, each stockholder named in the following 

table possesses sole voting and investment power over their shares of common stock, except for those jointly owned with that person’s spouse. 
Unless otherwise indicated below, the address of each person listed on the table is c/o Phio Pharmaceuticals Corp., 257 Simarano Drive, Suite 101,

CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS, AND DIRECTOR INDEPENDENCE

Since the past two years, there has not been, nor is there currently proposed, any transaction or series of related transactions to which we 
were or will be a party in which the amount involved exceeded or will exceed $120,000 and in which the other parties included or will include any 
of our directors, executive officers, holders of 5% or more of our voting securities, or any member of the immediate family of any of the foregoing 
persons, other than compensation arrangements with directors and executive officers, which are described where required in “Directors, Executive 
Officers and Corporate Governance,” “Executive Compensation,” and the transactions described below.

Procedures for Review, Approval or Ratification of Transactions with Related Persons 

Our Board of Directors has a policy to review and approve all transactions with directors, officers and holders of more than 5% of our 

voting securities and their affiliates. These policies and procedures are generally not in writing, but are evidenced by longstanding principles 
adhered to by our Board. The policy provides that, prior to Board of Director consideration of a transaction with such a related party, the material 
facts as to the related party’s relationship or interest in the transaction must be disclosed to the Board of Directors, and the transaction will not be 
considered approved by the Board of Directors unless a majority of the directors who are not interested in the transaction (if applicable) approve the 
transaction. Furthermore, when stockholders are entitled to vote on a transaction with a related party, the material facts of the related party’s 
relationship or interest in the transaction must be disclosed to the stockholders, who must approve the transaction in good faith.

Indemnification Agreements 

We have entered into indemnification agreements with each of our executive officers and directors. These agreements provide that, subject 

to limited exceptions and among other things, we will indemnify each of our executive officers and directors to the fullest extent permitted by law 
and advance expenses to each indemnitee in connection with any proceeding in which a right to indemnification is available.

Stock Purchase Agreement 

On January 6, 2017, the Company entered into a Stock Purchase Agreement (the “Stock Purchase Agreement”) by and among the 

Company, Phio Merger Sub, LLC, a Delaware limited liability company and wholly owned subsidiary of the Company, MirImmune Inc., a 
Delaware corporation (“MirImmune”), the stockholders of MirImmune as set forth on the signature pages thereto (each a “Seller” and collectively, 
the “Sellers”), and Alexey Wolfson, Ph.D., in his capacity as the Sellers’ Representative. Pursuant to the Stock Purchase Agreement, the Company 
acquired from the Sellers 100% of the issued and outstanding shares of capital stock of MirImmune for an aggregate of 275,036 shares of the 
Company’s common stock and an aggregate of 1,118,224 shares of Series C Convertible Preferred Stock, par value $0.0001 per share (the “Series 
C Convertible Preferred Stock”). Such consideration represented in the aggregate a number of shares of capital stock equal to approximately 
19.99% of the outstanding common stock immediately prior to the execution of the Stock Purchase Agreement, plus approximately 19.99% of the 
common stock underlying the Company’s outstanding Series B Convertible Preferred Stock, par value $0.0001 per share (the “Series B 
Convertible Preferred Stock”), immediately prior to the execution of the Stock Purchase Agreement, which were previously issued in the 
Company’s registered securities offering pursuant to a registration statement on Form S-1 (File No. 333-214199) (the “Financing”). On June 9, 
2017, with the approval of the Company’s stockholders in accordance with the stockholder approval requirements of Nasdaq Marketplace Rule 
5635, every ten shares of the Company’s Series C Convertible Preferred Stock outstanding were automatically converted into one share of common 
stock, such that no shares of Series C Convertible Preferred Stock remained issued or outstanding.

69

Under the terms of the Stock Purchase Agreement, if certain development or commercial milestones (the “Milestones”) are achieved 

within two years of the Closing (as defined therein), the Company will be required to either: (i) issue to the Sellers a number of shares of common 
stock (the “Milestone Shares”) equal to the sum of 251,909 shares of common stock (which represents 13% of the outstanding common stock and 
13% of the common stock underlying the shares of Series B Convertible Preferred Stock, in each case as of immediately following the closing of the 
Financing), plus an additional number of shares of common stock equal to 13% of the common stock issued upon exercise of any warrants issued 
under the Financing, which would result in the issuance of a maximum of 166,111 additional shares of common stock, but only to the extent that 
such warrants have been exercised prior to the Milestones being achieved; or (ii) pay the equivalent value of the Milestone Shares in cash to the 
Sellers, subject to certain adjustments set forth in the Stock Purchase Agreement. The Company received shareholder approval in accordance with 
Rule 5635 of the Nasdaq Marketplace Rules at its 2017 Annual Meeting of Stockholders to issue the Milestone Shares, if necessary. As of January 
9, 2019, two years from the Closing, the Company did not achieve the Milestones as defined in the Securities Purchase Agreement.

Pursuant to the Stock Purchase Agreement, we issued 81,781 shares of common stock and 332,499 shares of Series C Convertible 

Preferred Stock, which upon stockholder approval were converted into 33,249 shares of common stock, to Alexey Eliseev, Ph.D., a Seller in the 
agreement and co-founder of MirImmune. Dr. Eliseev was appointed the Chief Business Officer of the Company following the Company’s 
acquisition of MirImmune until his termination on September 15, 2017. The approximate dollar value of such shares was equal to $0.8 million. As 
the Company did not achieve the Milestones within two years of the Closing, Dr. Eliseev is not eligible to receive Milestone Shares. In connection 
with the Stock Purchase Agreement Dr. Eliseev also executed and delivered a three-year non-compete agreement with the Company under which 
Dr. Eliseev agreed to not interfere with the Company’s business or solicit the Company’s employees or business contacts.

Director Independence 

We believe that the Company benefits from having a strong and independent Board. For a director to be considered independent, the Board 
must determine that the director does not have any direct or indirect material relationship with the Company that would affect his or her exercise of 
independent judgment. On an annual basis, the Board reviews the independence of all directors under the applicable Nasdaq listing standards. The 
Company also considers each director’s affiliations with the Company and members of management, as well as significant holdings of Company 
securities. This review considers all known relevant facts and circumstances in making an independence determination. Based on this review, the 
Board of Directors has made an affirmative determination that all directors, other than Dr. Cauwenbergh, are independent. It was determined that 
Dr. Cauwenbergh lacks independence because of his status as the Company’s former Chief Executive Officer.

In addition, Nasdaq listing standards require that, subject to specified exceptions, each member of our Audit, Compensation and 
Nominating and Corporate Governance Committees be independent and that our Audit Committee members also satisfy independence criteria set 
forth in Rule 10A-3 under the Securities Exchange Act of 1934, as amended.

For additional information regarding director independence and committee memberships, see “Item 10—Directors, Executive Officers and 

Corporate Governance”.
