PART I  

ITEM 1.  BUSINESS  

Overview  

BioCryst Pharmaceuticals, Inc. is a biotechnology company focused on designing, optimizing and developing novel small molecule 

pharmaceuticals that block key enzymes essential for cancer, cardiovascular and autoimmune diseases and viral infections. Our most advanced 
drug candidate, BCX-1777, is an investigational purine nucleoside phosphorylase (PNP) inhibitor for the treatment of T-cell mediated 
disorders.  

Our Business Strategy  

Our business strategy is to use structure-based drug design technologies to develop innovative, small-molecule pharmaceuticals to treat a 
variety of diseases and disorders. We focus our drug development efforts on building potent, selective inhibitors of enzymes associated with 
targeted diseases. Enzymes are proteins that cause or enable biological reactions necessary for the progression of the disease or disorder. The 
specific enzymes on which we focus are called enzyme targets. BioCryst aims to design compounds that will inhibit an enzyme target by fitting 
the active site of a particular enzyme. Inhibition means interfering with the functioning of an enzyme target, thereby stopping or slowing the 
progression of the disease or disorder. The principal elements of our strategy are:  

•     Select and License Promising Enzyme Targets for the Development of Small-Molecule Pharmaceuticals.  We use our technical 

expertise and network of academic and industry contacts to evaluate and select promising enzyme targets to license for the development 
of small-molecule pharmaceuticals. We choose enzyme targets that meet as many of the following criteria as possible: 

•     serve important functions in disease pathways; 

•     have known animal or cell-based models that would be indicative of results in humans; 

•     address large potential markets and significant unmet medical needs, including pursuing niche markets where the results have 

potential application to broader markets and needs; 

•     have multiple potential clinical applications; and 

•     offer rapid development and commercialization opportunities. 

•     Focus on High Value-Added Structure-Based Drug Design Technologies. We focus our drug discovery activities and expenditures on 
applications of structure-based drug design technologies to design and develop drug candidates. Structure-based drug design is a process 
by which we design a drug candidate through detailed analysis of the enzyme target, which the drug candidate must inhibit in order to 
stop the progression of the disease or disorder. We believe that structure-based drug design is a powerful tool for efficient development 
of small-molecule drug candidates that have the potential to be safe, effective and relatively inexpensive to manufacture. Our structure-
based drug design technologies typically allow us to design and synthesize multiple drug candidates that inhibit the same enzyme target. 
We believe this strategy can lead to broad patent protection and enhance the competitive advantages of our compounds. 

•     Develop or License Inhibitors that are Promising Candidates for Commercialization. We test multiple compounds to identify those 
that are most promising for clinical development. We base our selection of promising development candidates on desirable product 

   
 
 
 
 
 
 
 
 
characteristics, such as initial indications of safety and efficacy. We believe that this focused strategy allows us to eliminate unpromising 
candidates from consideration sooner without incurring substantial clinical costs. In addition, we select drug candidates on the basis of 
their potential for relatively efficient Phase I and Phase II clinical trials that require fewer patients to initially indicate safety and 
efficacy. We will consider, however, more complex candidates with longer development cycles if we believe that they offer promising 
commercial opportunities. 

1  

An important element of our business strategy is to control fixed costs and overhead through contracting and entering into license 
agreements with other parties. We maintain a streamlined corporate infrastructure that focuses on our strongest areas of expertise. By 
contracting with other specialty organizations, we believe that we can control costs, enable our drug candidates to reach the market more 
quickly and reduce our business risk. Key elements of our contracting strategy include:  

•     Entering Into Relationships with Academic Institutions and Biotechnology Companies. Many academic institutions and biotechnology 
companies perform extensive research on the molecular and structural biology of potential drug development targets. By entering into 
relationships with these institutions, we believe we can significantly reduce the time, cost and risks involved in drug development. Our 
collaborative relationships with such organizations may lead to the licensing of one or more drug targets or compounds. Upon licensing 
a drug target or promising compound from one of these institutions, the scientists from the institution typically become working partners 
as members of our structure-based drug design teams. We believe this makes us a more attractive development partner to these scientists. 
In addition, we collaborate with outside experts in a number of areas, including crystallography, molecular modeling, combinatorial 
chemistry, biology, pharmacology, oncology, cardiology, immunology and infectious diseases. These collaborations enable us to 
complement our internal capabilities without adding costly overhead. We believe this strategy allows us to save valuable time and 
expense, and further diversify and strengthen our portfolio of drug candidates. An example of such a collaborative relationship is the 
arrangement that we have with The University of Alabama at Birmingham, or UAB, which has resulted in the initiation of several of our 
early drug development programs. 

•     Developing Drug Development Candidates or Licensing Them to Other Parties. We generally plan to advance drug candidates through 
initial and/or early-stage drug development. For larger disease indications requiring complex clinical trials, our strategy is to license drug 
candidates to pharmaceutical or biotechnology partners for final development and global marketing. We believe partnerships are a good 
source of development payments, license fees, milestone payments and royalties. They also reduce the costs and risks, and increase the 
effectiveness, of late-stage product development, regulatory approval, manufacturing and marketing. We believe that focusing on 
discovery and early-stage drug development while benefiting from our partners’ proven development and commercialization expertise 
will reduce our internal expenses and allow us to have a larger number of drug candidates progress to late-stage drug development. 
However, after establishing a lead product candidate, we are willing to license that candidate during any stage of the development 
process we determine to be beneficial to the company and to the ultimate development and commercialization of that drug candidate. For 
some smaller niche disease indications markets, we may choose to complete development, manufacture, and where appropriate market 
and distribute any approved drugs ourselves, such as BCX-1777 for T-cell leukemias.

Overview . The link between T-cell proliferation and the purine nucleoside phosphorylase, or PNP, enzyme was first discovered 

approximately twenty-five years ago when a patient, who was genetically deficient in PNP, exhibited limited T-cell activity, but reasonably 
normal activity of other immune functions. In other patients lacking PNP activity, the T-cell population was selectively depleted; however, B-
cell function tended to be normal. Based on these findings and the results of cell culture studies, inhibiting PNP produces selective suppression 
of T-cells without significantly impairing the function of other cells.  

The human immune system employs specialized cells, including T-cells, to control infection by recognizing and attacking disease-causing 

viruses, bacteria and parasites. T-cells are an essential part of the body’s immune system that serve a dual purpose to both orchestrate and 
participate in the body’s immune response. For the most part, this system works flawlessly to protect the body. However, when T-cells multiply 
uncontrollably, T-cell proliferative diseases, including T-cell cancers, occur.  

Acute Lymphoblastic Leukemia . The most common form of leukemia in children is acute lymphoblastic leukemia (also known as ALL). 

According to the American Cancer Society, 3,830 new cases (adult and children combined) will be diagnosed in the United States in 2004. 
ALL results from an acquired injury to the DNA of a single cell in the bone marrow.  

T-cell Lymphoma . Lymphoma is a general term for a group of cancers that originate in the lymphatic system. About 54,000 Americans will 

be diagnosed with a non-Hodgkin’s lymphoma in 2004 and approximately 15% of these will be considered T-cell lymphomas. T-cell 
lymphoma results when a T-lymphocyte (a type of white blood cell) undergoes a malignant change and begins to multiply, eventually crowding 
out healthy cells and creating tumors, which enlarge the lymph nodes and invade other sites in the body. Cutaneous T-cell lymphoma (CTCL) 
is a primary skin neoplasm and accounts for nearly 50% of all T-cell malignancies.  

T-cell Mediated Autoimmune Diseases. Diseases such as psoriasis, rheumatoid arthritis, multiple sclerosis, and Crohn’s appear to have 

activated T-cells as a major part of their pathogenesis. Therefore, inhibition and/or elimination of such cells could have a profound and 
beneficial effect on these diseases.  

PNP Inhibition . PNP is an enzyme that plays an important role in T-cell proliferation, because it is necessary to maintain normal DNA 

synthesis in T-cells. Selective inhibition of PNP has an accumulation effect on certain nucleosides, including deoxyguanosine. As the 
concentration of deoxyguanosine increases within T-cells, it is converted by specific enzymes to deoxyguanosine triphosphate. A high 
concentration of deoxyguanosine triphosphate in T-cells blocks DNA synthesis and thus inhibits cell division.  

Our PNP Inhibitor(s)  

Background . In June 2000, we licensed a series of potent inhibitors of purine nucleoside phosphorylase from Albert Einstein College of 
Medicine of Yeshiva University (AECOM) and Industrial Research, Ltd, New Zealand (IRL). The lead drug candidate from this collaboration, 
BCX-1777, is a more potent inhibitor of human lymphocyte proliferation than other previously known PNP inhibitors. Extensive preclinical 
studies and early patient data indicate that BCX-1777 can modulate T-cell activities. BCX-1777 is an investigational PNP inhibitor for the 
potential treatment of T-cell leukemias and lymphomas.  

During 2002, we exercised the option to add a new compound, BCX-4208, to the series of inhibitors of PNP licensed from AECOM and 
IRL. Preclinical results indicate that BCX-4208 is a more potent inhibitor than BCX-1777. We plan to develop BCX-4208 for autoimmune 
diseases such as psoriasis and rheumatoid arthritis.  

PNP Inhibitor (BCX-1777)  

Overview  

The first clinical trial with an intravenous formulation of BCX-1777 is a Phase I clinical trial for patients with relapsed or refractory T-cell 
acute lymphoblastic leukemia (ALL) and T-cell lymphoma. The Phase I trial is an open-label dose-escalation study of BCX-1777 in relapsed or 
refractory aggressive T-cell malignancies,  

3  

which are among the most difficult cancers to treat by current therapies. Because of the clinical results seen to this point and some additional 
testing by our colleagues at the M.D. Anderson Cancer Center, we started three additional trials in 2003 for refractory patients with other types 
of hematologic malignancies, cutaneous T-cell lymphoma, and solid tumors. Preclinical studies at the M.D. Anderson Cancer Center indicate 
that BCX-1777 induces the same biochemical changes in various other types of leukemia cells that are responsible for the inhibition of T-
leukemia cells, which suggest that BCX-1777 may be even more broadly applicable than originally expected. Initial Phase I clinical results in 
patients with B-cell acute lymphoblastic leukemia have been encouraging, and we plan to pursue additional B-cell leukemia clinical studies 
during 2004.  

Current Development Strategy  

 
BCX-1777 Clinical Development for Aggressive T-cell Malignancies . The Phase I clinical trial was developed in close collaboration with 
experts at The University of Texas M. D. Anderson Cancer Center. Despite encouraging results observed with other T-cell specific agents, the 
prognosis for patients with relapsed or refractory leukemia or lymphoma is poor and treatment options remain limited. The goal of the Phase I 
clinical trial is to determine the safety, biochemical and metabolic profile and therapeutic effect produced by BCX-1777 as it relates to the 
proposed mechanism of action in the inhibition of proliferating T-lymphocytes in patients with T-cell ALL or T-cell lymphoma. Our strategy 
for future development of BCX-1777 is to pursue with the FDA both orphan drug and fast-track designations. We are also designing a Phase II 
trial for intravenous BCX-1777, which, assuming successful completion of the current trials, we plan to begin in early 2004 to treat patients 
with T-cell leukemias. We also plan to initiate a second Phase II trial in early 2004 with intravenous BCX-1777 for treatment of patients with 
cutaneous T-cell lymphoma (CTCL). Our current intent is for BioCryst itself to market and distribute BCX-1777 in the United States for 
treatment of T-cell cancers.  

Early Phase I studies with oral BCX-1777 are currently in progress at the Cleveland Clinic, and we plan to initiate a Phase I/II CTCL 

clinical trial with oral BCX-1777 during the first half of 2004.  

PNP Inhibitor (BCX-4208)  

Overview  

We believe that the results to date of our Phase I trials of BCX-1777 support the principle that inhibition of PNP has a direct effect on 
proliferation of activated T-lymphocytes. We are now developing BCX-4208, a second-generation PNP inhibitor, as a drug candidate for the 
treatment of T-cell mediated autoimmune diseases, including psoriasis. Although BCX-4208 and BCX-1777 are both investigational PNP 
inhibitors, BCX-4208 differs from BCX-1777 in significant ways. For example, BCX-4208 is more potent, with the ability to modulate T-cell 
activity for longer period of time. Thus, BCX-4208 has potential advantages over BCX-1777 for the treatment of diseases requiring long-term, 
chronic administration of a PNP inhibitor.  

Current Development Strategy  

During 2003, we conducted a series of preclinical studies of BCX-4208 and have begun preclinical toxicology studies, with the goal of 

advancing BCX-4208 into Phase I clinical development for treatment of patients with psoriasis in the second half of 2004.  

Tissue Factor/Factor VIIa  

Overview  

A series of complicated reactions take place in the body whenever a blood clot begins to form. The major initiator of these reactions is an 
enzyme system called the tissue factor/factor VIIa (TF/FVIIa) complex. Animal tests show that various inhibitors of the TF/FVIIa complex can 
minimize blood clot formation as well as inflammatory responses. This sort of inhibition has been tested with a number of biological agents 
including the natural inhibitor of the pathway, synthetic peptides and protein inhibitors, and antibodies against tissue factor. However, there are 
no small molecule drugs currently on the market that intervene at the TF/FVIIa level.  

We believe that small molecule inhibitors of TF/FVIIa may potentially be useful for treating acute coronary syndromes and complications 

associated with cardiovascular procedures, such as coronary angioplasty and  

4  

stent insertions, because any type of damage to arteries and blood vessels exposes tissue factor, which then triggers clot formation. Myocardial 
infarction, unstable angina, and restenosis during and following angioplasty procedures are all potential treatment targets. In addition, tissue 
factor is involved in angiogenesis, or new blood vessel growth, and inhibitors of the TF/FVIIa complex are believed to have potential as anti-
angiogenesis agents for use in oncology.  

Background . We have an agreement with Sunol Molecular Corp. to expedite the discovery of new drug candidates designed to inhibit 

TF/FVIIa. Under the terms of this agreement, Sunol supplies us protein for our drug design program.  

Current Development Strategy  

We are continuing to design and synthesize groups of compounds that are potent and selective inhibitors of TF/FVIIa and further 

optimization is ongoing to identify a compound for preclinical development of a TF/FVIIa inhibitor in oral form.  

Hepatitis C  

 
Overview  

Hepatitis C virus (HCV) infection has been described in the New England Journal of Medicine as the nation’s most common chronic blood-

borne infection. Up to 3% of the world’s population has been infected with HCV. According to the National Centers for Disease Control, as 
many as 75-85% of those infected with HCV will have chronic infection and 70% of those will develop chronic liver disease. While there are 
several approved treatments for chronic HCV using a combination therapy of interferon and ribavirin, there are some potentially severe side 
effects to these treatments.  

Background . In June 2000, we licensed intellectual property from Emory University related to the hepatitis C polymerase target associated 

with hepatitis C viral infections. Under the terms of the agreement, the research investigators from Emory provide us with materials and 
technical insight into the target.  

Current Development Strategy  

We are targeting HCV polymerase through collaborative and in-house efforts. Specifically, we are focused on development of orally active 
inhibitors against the RNA-dependent RNA polymerase. Competition for this target is less intense than for the HCV protease target and history 
suggests the likelihood of designing a useful inhibitor against this target may be better than for the more difficult protease.  

Currently, we are designing, synthesizing and screening potential compounds against HCV polymerase. Specifically, our scientists are 
measuring the potency and ability of potential drug candidates to block the replication of HCV polymerase in vitro, or in test tubes. These 
experiments measure the potency of each selected compound’s ability to block replication. Advanced screening is also underway to measure 
the fit of promising compounds in the HCV polymerase active site using X-ray crystallography and computer molecular modeling. The goal is 
to identify a series of compounds that are potent in vitro inhibitors of the active site of the HCV polymerase for further testing and lead 
optimization.  

We also have agreements in place with the National Institute of Allergy and Infectious Diseases, a unit of The National Institutes of Health, 

and the U.S. Army Medical Research Institute of Infectious Diseases to assay promising inhibitors from the HCV polymerase program for 
activity against Severe Acute Respiratory Syndrome (SARS), West Nile and Ebola viruses.  

Structure-Based Drug Design  

Structure-based drug design is a drug discovery approach by which we design synthetic compounds from detailed structural knowledge of 

the active sites of enzyme targets associated with particular diseases. Enzymes are proteins that act as catalysts for many vital biological 
reactions. Our goal generally is to design a compound that will fit in the active site of an enzyme (the active site of an enzyme is the area into 
which a chemical or biological molecule fits to initiate a biochemical reaction) and thereby interfere with the progression of disease.  

5  

Our structure-based drug design involves the application of both traditional biology and medicinal chemistry and an array of advanced 
technologies. We use X-ray crystallography, computer modeling of molecular structures and advanced chemistry techniques to focus on the 
three-dimensional molecular structure and active site characteristics of the enzymes that control cellular biology.  

We believe that structure-based drug design technologies are superior to drug screening techniques. By identifying the target enzyme in 
advance and by discovering the chemical and molecular structure of the enzyme, we believe it is possible to design a better drug to interact 
with the enzyme. In addition, the structural data obtained by X-ray crystallographic analysis allow additional analysis and compound 
modification at each stage of the biological evaluation. This capability makes structure-based drug design a powerful tool for efficient 
development of drugs that are highly specific for particular enzyme target sites.  

Research and Development  

We initiated our research and development program in 1986, with drug synthesis beginning in 1987. We have assembled a scientific 

research staff with expertise in a broad base of advanced research technologies including protein biochemistry, X-ray crystallography, 
chemistry and pharmacology. Our research facilities include protein biochemistry and organic synthesis laboratories, testing facilities, X-ray 
crystallography, computer and graphics equipment and facilities to make drug candidates on a small scale.  

During the years ended December 31, 2001, 2002 and 2003, we spent an aggregate of $40.1 million on research and development. 
Approximately $26.4 million of that amount was spent on in-house research and development, and $13.7 million was spent on contract 
research and development.  

Collaborative Relationships  

 
Corporate Alliances  

Sunol Molecular Corp . In April 1999, we entered into an agreement with Sunol. This agreement requires Sunol to conduct research and 
supply us with protein targets for drug design to expedite the discovery of new drug candidates designed to inhibit tissue factor/factor VIIa for 
our cardiovascular program.  

Academic Alliances  

The University of Alabama at Birmingham . We have had a close relationship with The University of Alabama at Birmingham (UAB), 

since our formation. Our Chairman and Chief Executive Officer, Dr. Charles E. Bugg, was the previous Director of the UAB Center for 
Macromolecular Crystallography, and our President, Chief Operating Officer and Medical Director, Dr. J. Claude Bennett, was the former 
President of UAB, the former Chairman of the Department of Medicine at UAB and a former Chairman of the Department of Microbiology at 
UAB. Several of our consultants are employed by UAB. UAB has a large X-ray crystallography center with approximately 110 full-time staff 
members and approximately $15 million in research grants and contract funding in 2003. Several of our early programs originated at UAB.  

We currently have agreements with UAB for influenza neuraminidase and complement inhibitors. Under the terms of these agreements, 
UAB performed specific research for us in return for research payments and license fees. UAB has granted us certain rights to any discoveries 
in these areas resulting from research developed by UAB or jointly developed with us. We have agreed to pay royalties on sales of any 
resulting product and to share in future payments received from other third-party collaborators. We have completed the research under the 
UAB influenza agreement. We funded the research program under the complement inhibitors agreement through March 2002, which entitled us 
to an assignment of, or a right to an exclusive license for, any inhibitors of specified complement enzymes developed by UAB scientists during 
the period of support or for a one-year period thereafter. These two agreements have initial 25-year terms, are automatically renewable for five-
year terms throughout the life of the last patent and are terminable by us upon three-months’ notice and by UAB under certain circumstances.  

Albert Einstein College of Medicine of Yeshiva University and Industrial Research, Ltd, New Zealand . In June 2000, we licensed a series 

of potent inhibitors of purine nucleoside phosphorylase, or PNP, from Albert Einstein College of Medicine of Yeshiva University and 
Industrial Research, Ltd., New Zealand. The lead drug  

6  

candidate from this collaboration is BCX-1777. We have the rights to develop and ultimately distribute this, or any other, drug candidate that 
might arise from research on these inhibitors. For example, in 2003 we obtained the rights to another compound from this series, BCX-4208, 
which is currently in preclinical development. We have agreed to pay certain milestone payments for future development of these inhibitors, 
pay certain royalties on sales of any resulting product, and to share in future payments received from other third-party collaborators, if any. We 
can terminate this agreement at any time by giving 60 days advance notice.  

Emory University . In June 2000, we licensed intellectual property from Emory University related to the hepatitis C polymerase target 
associated with hepatitis C viral infections. Under the terms of the agreement, the research investigators from Emory provide us with materials 
and technical insight into the target. We have agreed to pay Emory royalties on sales of any resulting product and to share in future payments 
received from other third party collaborators, if any. We can terminate this agreement at any time by giving 90 days advance notice.  

Patents and Proprietary Information  

Our success will depend in part on our ability to obtain and enforce patent protection for our products, methods, processes and other 

proprietary technologies, preserve our trade secrets, and operate without infringing on the proprietary rights of other parties, both in the United 
States and in other countries. We own or have rights to certain proprietary information, proprietary technology, issued and allowed patents and 
patent applications which relate to compounds we are developing. We actively seek, when appropriate, protection for our products, proprietary 
technology and proprietary information by means of U.S. and foreign patents, trademarks and contractual arrangements. In addition, we rely 
upon trade secrets and contractual arrangements to protect certain of our proprietary information, proprietary technology and products.  

As of January 31, 2004, we have been issued 21 U.S. patents that expire between 2009 and 2021 and that relate to our PNP and 
neuraminidase inhibitor compounds. We have licensed four additional patents and two pending patents from Albert Einstein College of 
Medicine of Yeshiva University and one patent from Emory University. We have also filed patent applications for new processes to prepare 
certain PNP inhibitors. Additionally, we have 16 U.S. patent applications pending related to PNP, neuraminidase, RNA viral polymerase, 
paramyxovirus neuraminidase, and serine protease inhibitors. Our pending applications may not result in issued patents, and our patents may 
not provide us with sufficient protection against competitive products or otherwise be commercially available.  

Our success is also dependent upon the skills, knowledge and experience of our scientific and technical personnel, none of which is 

patentable. To help protect our rights, we require all employees, consultants, advisors and collaborators to enter into confidentiality agreements 
which prohibit the disclosure of confidential information to anyone outside of our company and requires disclosure and assignment to us of 
their ideas, developments, discoveries and inventions. These agreements may not provide adequate protection for our trade secrets, know-how 
or other proprietary information in the event of any unauthorized use or disclosure or the lawful development by others of such information.  

 
Marketing and Sales  

We currently plan to market, distribute and sell BCX-1777 in the U.S. for use in treatment of T-cell cancers. Although our general strategy 

is to rely on major marketing companies for worldwide commercialization of most products we may develop, we believe that we can manage 
the highly specialized oncology market for BCX-1777 within the U.S. Most patients with advanced T-cell malignancies in the U.S. are treated 
at major referral cancer centers, and we expect that many of these centers will be participating in our Phase II trials and will thus be familiar 
with BCX-1777 if it reaches the market. However, we lack experience in marketing, distributing and selling pharmaceutical products. Our 
general strategy is to rely on collaborators, licensees or arrangements with others to provide for the marketing, distribution and sales of 
products we may develop. We may not be able to establish and maintain acceptable commercial arrangements with collaborators, licensees or 
others to perform such activities.

Competition  

The pharmaceutical and biotechnology industries are intensely competitive. Many companies, including biotechnology, chemical and 
pharmaceutical companies, are actively engaged in activities similar to ours, including research and development of drugs for the treatment of 
infectious, inflammatory and cardiovascular diseases and disorders. Many of these companies have substantially greater financial and other 
resources, larger research and development staffs, and more extensive marketing and manufacturing organizations than we do. In addition, 
some of them have considerable experience in preclinical testing, clinical trials and other regulatory approval procedures. There are also 
academic institutions, governmental agencies and other research organizations that are conducting research in areas in which we are working. 
They may also market commercial products, either on their own or through collaborative efforts.  

We expect to encounter significant competition for any of the pharmaceutical products we plan to develop. Companies that complete 
clinical trials, obtain required regulatory approvals and commence commercial sales of their products before their competitors may achieve a 
significant competitive advantage. In addition, several pharmaceutical and biotechnology firms, including major pharmaceutical companies and 
specialized structure-based drug design companies, have announced efforts in the field of structure-based drug design and in the fields of PNP, 
hepatitis C, and tissue factor/factor VIIa.  

In order to compete successfully, we must develop proprietary positions in patented drugs for therapeutic markets that have not been 
satisfactorily addressed by conventional research strategies and, in the process, expand our expertise in structure-based drug design. Our 
products, even if successfully tested and developed, may not be adopted by physicians over other products and may not offer economically 
feasible alternatives to other therapies.  

Government Regulation  

The FDA regulates the pharmaceutical and biotechnology industries in the United States, and our drug candidates are subject to extensive 
and rigorous domestic government regulations prior to commercialization. The FDA regulates, among other things, the development, testing, 
manufacture, safety, efficacy, record-keeping, labeling, storage, approval, advertising, promotion, sale and distribution of pharmaceutical 
products. In foreign countries, our products are also subject to extensive regulation by foreign governments. These government regulations will 
be a significant factor in the production and marketing of any pharmaceutical products that we develop. Failure to comply with applicable FDA 
and other regulatory requirements at any stage during the regulatory process may subject us to sanctions, including:  

•     delays; 

•     warning letters; 

•     fines; 

•     product recalls or seizures; 

•     injunctions; 

•     penalties; 

•     refusal of the FDA to review pending market approval applications or supplements to approval applications; 

•     total or partial suspension of production; 

•     civil penalties; 

 
 
 
 
 
 
 
 
 
 
•     withdrawals of previously approved marketing applications; and 

•     criminal prosecutions. 

The regulatory review and approval process is lengthy, expensive and uncertain. Before obtaining regulatory approvals for the commercial 
sale of any products, we or our licensees must demonstrate that our product candidates are safe and effective for use in humans. The approval 
process takes many years, substantial expenses may be incurred and significant time may be devoted to clinical development.  

8  

Before testing potential candidates in humans, we carry out laboratory and animal studies to determine safety and biological activity. After 
completing preclinical trials, we must file an investigational new drug application, including a proposal to begin clinical trials, with the FDA. 
We have filed nine investigational new drug applications to date and plan to file, or rely on future partners to file, additional investigational 
new drug applications in the future as our potential drug candidates advance to that stage of development. Thirty days after filing an 
investigational new drug application, a Phase I human clinical trial can start unless the FDA places a hold on the study.  

Our Phase I trials are designed to determine safety in a small group of patients or healthy volunteers. We also assess tolerances and the 
metabolic and pharmacologic actions of our drug candidates at different doses. After we complete the initial trials, we conduct Phase II trials to 
assess safety and efficacy and establish the optimal dose in patients. If Phase II trials are successful, we or our licensees conduct Phase III trials 
to verify the results in a larger patient population. Phase III trials are required for FDA approval to market a drug. A Phase III trial may require 
hundreds or even thousands of patients and is the most expensive to conduct. The goal in Phase III is to collect enough safety and efficacy data 
to obtain FDA approval for treatment of a particular disease. For some clinical indications that are especially serious and for which there are no 
effective treatments, such as refractory cancers, conditional approval can be obtained following Phase II trials.  

Initiation and completion of the clinical trial phases are dependent on several factors including things that are beyond our control. For 

example, the clinical trials are dependent on patient enrollment, but the rate at which patients enroll in the study depends on:  

•     the size of the patient population we intend to treat; 

•     the availability of patients; 

•     the willingness of patients to participate; and 

•     the patient meeting the eligibility criteria. 

Delays in planned patient enrollment may result in increased expense and longer development timelines.  

After completion of the clinical trials of a product, we or our licensees must submit a new drug application to the FDA for marketing 
approval before commercialization of the product. The FDA may not grant approval on a timely basis, if at all. The FDA, as a result of the 
Food and Drug Administration Modernization Act of 1997, has six months to review and act upon license applications for priority therapeutics 
that are for life-threatening or unmet medical needs. Standard reviews can take between one and two years, and can even take longer if 
significant questions arise during the review process. The FDA may withdraw any required approvals, once obtained.  

In addition to clinical development regulations, we and our contract manufacturers and collaborators must comply with the applicable FDA 

current good manufacturing practice (“GMP”) regulations. GMP regulations include requirements relating to quality control and quality 
assurance as well as the corresponding maintenance of records and documentation. Manufacturing facilities are subject to inspection by the 
FDA. Such facilities must be approved before we can use them in commercial manufacturing of our potential products. We or our contract 
manufacturers may not be able to comply with the applicable GMP requirements and other FDA regulatory requirements. If we or our contract 
manufacturers fail to comply, our business, financial condition and results of operations will be materially adversely affected.  

Human Resources  

As of February 27, 2004, we had 46 employees, of whom 35 were engaged in research and development and 11 were in general and 

administrative functions. Our scientific staff, 20 of whom hold Ph.D. or M.D. degrees, has diversified experience in biochemistry, 
pharmacology, X-ray crystallography, synthetic organic chemistry, computational chemistry, and medicinal chemistry. We consider our 
relations with our employees to be satisfactory.

Scientific Advisory Board and Consultants  

Our scientific advisory board is comprised of five scientific advisors who are leaders in certain of our core disciplines or who otherwise 
have specific expertise in our therapeutic focus areas. We also have consulting agreements with a number of other scientists with expertise in 
our core disciplines or who are specialists in diseases or treatments on which we focus. The scientific advisory board meets as a group at 
scheduled meetings and the consultants meet more frequently, on an individual basis, with our scientific personnel and management to discuss 
our ongoing research and drug discovery and development projects. The scientific advisory board consists of the following individuals:  

Name 

Albert F. LoBuglio, M.D. (Chairman)

Sciences at the University of California, San Diego School of Medicine.  
                  Professor and Chairman of the Department of Pharmacology of Cornell 
Medical College and the Revlon Pharmaceutical Professor of 
Pharmacology and Toxicology.  

                  President of the Hauptman-Woodward Medical Research Institute, Inc. 

(formerly the Medical Foundation (Buffalo), Inc.), and Research Professor 
in Biophysical Sciences at the State University of New York (Buffalo). 
Recipient of the Nobel Prize in Chemistry (1985).  

                  Professor, Molecular Biology and Genetics Department at The Johns 

Hopkins University School of Medicine, retired, and Scientific Director of 
The Institute for Bioenergy Alternatives. Recipient of the Nobel Prize in 
Medicine (1978).  

The scientific advisors and the consultants are reimbursed for their expenses and receive nominal cash compensation in connection with 
their service and have been issued options and/or shares of common stock. The scientific advisors and the consultants are all employed by or 
have consulting agreements with entities other than us, some of which may compete with us in the future. The scientific advisors and the 
consultants are expected to devote only a small portion of their time to our business, although no specific time commitment has been 
established. They are not expected to participate actively in our affairs or in the development of our technology. Several of the institutions with 
which the scientific advisors and the consultants are affiliated may adopt new regulations or policies that limit the ability of the scientific 
advisors and the consultants to consult with us. The loss of the services of the scientific advisors and the consultants could adversely affect us 
to the extent that we are pursuing research or development in areas relevant to the scientific advisors’ and consultants’ expertise. To the extent 
members of our scientific advisory board or the consultants have consulting arrangements with or become employed by any of our competitors, 
we could be materially adversely affected.  

Any inventions or processes independently discovered by the scientific advisors or the consultants may not become our property and will 
probably remain the property of such persons or of such persons’ employers. In addition, the institutions with which the scientific advisors and 
the consultants are affiliated may make available the research services of their personnel, including the scientific advisors and the consultants, 
to our competitors pursuant to sponsored research agreements. We require the scientific advisors and the consultants to enter into 
confidentiality agreements which prohibit the disclosure of confidential information to anyone outside of our company and require disclosure 
and assignment to us of their ideas, developments, discoveries or inventions. However, our competitors may gain access to trade secrets and 
other proprietary information developed by us and disclosed to the scientific advisors and the consultants.

ITEM 7.  MANAGEMENT’S DISCUSSION AND ANALYSIS OF  
FINANCIAL CONDITION AND RESULTS OF OPERATIONS  

This Annual Report on Form 10-K contains certain statements of a forward-looking nature relating to future events or the future financial 

performance of the Company. Such statements are only predictions and the actual events or results may differ materially from the results 
discussed in the forward-looking statements. Factors that could cause or contribute to such differences include those discussed below as well 
as those discussed in other filings made by the Company with the Securities and Exchange Commission.  

Overview  

Since our inception in 1986, we have been engaged in research and development activities and organizational efforts, including:  

•     identification and licensing of enzyme targets; 

•     drug discovery; 

•     structure-based design of drug candidates; 

•     small-scale synthesis of compounds; 

•     conducting preclinical studies and clinical trials; 

   
 
 
 
 
 
 
 
  
   
                    
 
                                                                    
   
                    
    
                         
                    
                    
                    
                    
     
•     recruiting our scientific and management personnel; 

•     establishing laboratory facilities; and 

•     raising capital. 

Our revenues have generally been limited to license fees, milestone payments, interest income, and collaboration research and development 

fees. The Company recognizes revenue in accordance with SEC Staff Accounting Bulletin No. 104, Revenue Recognition (“SAB No. 104”). 
Research and development revenue on cost-reimbursement agreements is recognized as expenses are incurred, up to contractual limits. 
Research and development fees, license fees and milestone payments are recognized as revenue when the earnings process is complete, the 
Company has no further continuing performance obligations and has completed its performance under the terms of the agreement, in 
accordance with SAB No. 104. License fees and milestone payments received under licensing agreements that are related to future performance 
are deferred and taken into income as earned over the estimated drug development period. The Company has not received any revenues or 
royalties from the sale of licensed pharmaceutical products. It could be several years, if ever, before we will recognize significant revenue from 
royalties received pursuant to our license agreements or revenue directly from product sales. Future revenues, if any, are likely to fluctuate 
substantially from quarter to quarter.  

We have incurred operating losses since our inception. Our accumulated deficit at December 31, 2003 was $104.7 million. We will require 

substantial expenditures relating to the development of our current and future drug candidates. During the three years ended December 31, 
2003, we spent 34.1% of our research and development expenses on contract research and development, including:  

•     payments to consultants; 

•     funding of research at academic institutions; 

•     large scale synthesis of compounds; 

•     preclinical studies; 

•     engaging investigators to conduct clinical trials; 

•     hiring contract research organizations to monitor and gather data on clinical trials; and 

•     using statisticians to evaluate the results of clinical trials. 

The above expenditures for contract research and development for our current and future drug candidates will vary from quarter to quarter 
depending on the status of our research and development projects. For example, on June 25, 2002, we announced preliminary Phase III clinical 
trial data for peramivir, our investigational oral  

13  

influenza neuraminidase inhibitor. The trial indicated no statistically significant difference in the primary efficacy endpoint between groups 
treated with peramivir and groups treated with placebo. Based on these data, we discontinued the development of peramivir. During the first 
nine months of 2002, our cash expenses related to this trial were approximately $4 million. After terminating the development of peramivir, the 
Company streamlined its operations, reducing its workforce from 75 employees to 45 employees in order to conserve its resources and provide 
a longer timeframe in which to advance its other programs.  

Changes in our existing and future research and development and collaborative relationships will also impact the status of our research and 

development projects. Although we may, in some cases, be able to control the timing of development expenses, in part by accelerating or 
decelerating certain of these costs, many of these costs will be incurred irrespective of whether we are able to discover drug candidates or 
obtain collaborative partners for commercialization. As a result, we believe that quarter-to-quarter comparisons of our financial results are not 
necessarily meaningful and should not be relied upon as an indication of future performance. If we fail to meet the research, clinical and 
financial expectations of securities analysts and investors, it could have a material adverse effect on the price of our common stock.  

Year Ended December 31, 2003 Compared with the Year Ended December 31, 2002  

Collaborative and other research and development revenues increased in 2003 to $653,000 compared to $0 in the same period last year, 
primarily due to a payment from 3-Dimensional Pharmaceuticals Inc. (3DP), a wholly-owned subsidiary of Johnson & Johnson, for certain 
rights related to complement system inhibitors discovered during the term of our collaborative research agreement. In addition, our revenues 
include $153,000 from the National Institutes of Health related to the $300,000 first year grant received during 2003 for our hepatitis C 
inhibitor program. Interest income for 2003 was $980,000, a 44.8% decrease compared to $1,775,000 in 2002. This decrease was due to a 

 
 
 
 
 
 
 
 
 
 
 
reduction in cash and a lower interest rate environment in 2003.  

Research and development expenses decreased 25.5% to $11,522,000 for 2003 from $15,473,000 in 2002. The decrease in expenses during 
2003 was primarily due to the costs incurred by BioCryst during 2002 to complete a Phase III clinical trial for peramivir, a drug candidate that 
was discontinued in June 2002. In addition, personnel costs were 34% lower during 2003 as a result of the reduction in our staff following the 
termination of the peramivir program.  

General and administrative expenses decreased slightly to $2,812,000 in 2003 from $2,856,000 in 2002. In addition, as a result of the 
termination of the peramivir program effective June 25, 2002, we recorded a non-cash impairment loss of $373,900 in 2002 related to the 
influenza patents. There were no impairment charges recorded in 2003.  

The net loss for the year ended December 31, 2003 was $12,700,000, or $0.72 per share, compared to a net loss of $16,929,000, or $0.96 

per share in 2002.  

Year Ended December 31, 2002 Compared with the Year Ended December 31, 2001  

Collaborative and other research and development revenue decreased 100.0% to $0 in 2002 from $7,736,976 in 2001, primarily due to a 
change in accounting estimate following Ortho-McNeil Pharmaceutical, Inc. (Ortho-McNeil) and The R.W. Johnson Pharmaceutical Research 
Institute’s (RWJPRI) notice of termination of the worldwide license agreement with us to develop and market products to treat and prevent 
viral influenza. As a result of this termination, we recognized all remaining deferred revenues and expenses related to this agreement during the 
second and third quarters of 2001. Interest and other income decreased 48.1% to $1,774,524 in 2002 from $3,420,658 in 2001, primarily due to 
a reduction in cash from the funding of operations and a lower interest rate environment in 2002.  

Research and development expenses increased 18.2% to $15,473,491 in 2002 from $13,091,057 in 2001. The increase in expenses is 
primarily attributable to the clinical trial expenses incurred to complete a Phase III trial for peramivir, prior to the termination of this program 
in June 2002, plus animal studies related to peramivir and our other programs.  

General and administrative expenses increased 9.5% to $2,855,804 in 2002 from $2,608,392 in 2001. The increase is primarily due to an 

increase in expenses related to the adoption of a stockholder rights plan, insurance and other professional fees. Royalty expense decreased 
100.0% to $0 in 2002 from $443,697 in 2001. This  

14  

decrease is directly attributable to the change in accounting estimate resulting from the termination of our worldwide license agreement by 
Ortho-McNeil and RWJPRI for our neuraminidase inhibitor, peramivir. As a result of the termination of this program effective June 25, 2002, 
we also recorded a non-cash impairment loss of $373,900 in 2002 related to the influenza patents. There were no impairment charges recorded 
in 2001.  

Liquidity and Capital Resources  

Cash expenditures have exceeded revenues since the Company’s inception. Our operations have principally been funded through various 

sources, including the following:  

•     public offerings and private placements of equity and debt securities, 

•     equipment lease financing, 

•     facility leases, 

•     collaborative and other research and development agreements (including licenses and options for licenses), 

•     research grants and 

•     interest income. 

In addition, we have attempted to contain costs and reduce cash flow requirements by renting scientific equipment and facilities, 
contracting with other parties to conduct certain research and development and using consultants. We expect to incur additional expenses, 
potentially resulting in significant losses, as we continue to pursue our research and development activities and undertake additional preclinical 
studies and clinical trials of compounds which have been or may be discovered. We also expect to incur substantial expenses related to the 
filing, prosecution, maintenance, defense and enforcement of patent and other intellectual property claims.  

 
 
 
 
 
 
 
On June 25, 2002, we announced we were discontinuing the development of peramivir, our investigational oral influenza neuraminidase 
inhibitor designed to treat and prevent influenza. After terminating the development of peramivir, the Company streamlined its operations in 
order to conserve its resources and provide a longer timeframe in which to advance its other programs.  

On August 5, 2002, at the request of Dr. Charles E. Bugg, our Chairman and Chief Executive Officer and Dr. J. Claude Bennett, our 
President, Chief Operating Officer and Medical Director, our Compensation Committee and board of directors approved a 25% reduction in 
their salaries, effective August 1, 2002. On December 8, 2003, the Compensation Committee and board of directors restored their salaries to 
the full amount in effect prior to August 1, 2002. This change became effective on January 1, 2004. In the event of any change of control of the 
Company, any cumulative salary reductions during the period from August 1, 2002 through December 31, 2003 would become due and 
payable to them. The aggregate monthly amount of the reduction was $14,677.  

On October 24, 2003, our compensation committee voted to pay Dr. Charles E. Bugg, our Chairman and Chief Executive Officer, $484,500 

as consideration for the cancellation of options held by Dr. Bugg to purchase 170,000 shares of our common stock. The expiration date of the 
options was November 18, 2003, and the exercise price of the options was $6.00 per share.  

The Company invests its excess cash principally in U.S. marketable securities from a diversified portfolio of institutions with strong credit 

ratings and in U.S. government and agency bills and notes, and by policy, limits the amount of credit exposure at any one institution. These 
investments are generally not collateralized and mature within three years. The Company has not realized any losses from such investments. In 
addition, at December 31, 2003, approximately $4.4 million was invested in the Merrill Lynch Premier Institutional Fund, which invests 
primarily in commercial paper, U.S. government and agency bills and notes, corporate notes, certificates of deposit and time deposits. The 
Merrill Lynch Premier Institutional Fund is not insured. At December 31, 2003, our cash, cash equivalents and securities held-to-maturity were 
$25.7 million, a decrease of $10.4 million from December 31, 2002, principally due to the funding of current operations. We raised an 
additional $21.3 million of capital during February 2004 through a registered offering of our common stock to selected institutional investors.  

15  

We have financed some of our equipment purchases with lease lines of credit. We currently have a $500,000 general line of credit with our 

bank, secured by a pledge of $600,000 in marketable securities. There was nothing drawn against this line as of December 31, 2003. In July 
2000, we renegotiated our lease for our current facilities, which will expire on June 30, 2010. We have an option to renew the lease for an 
additional five years at the current market rate in effect on June 30, 2010 and a one-time option to terminate the lease on June 30, 2008 for a 
termination fee of approximately $124,000. The lease, as amended effective July 1, 2001 for an additional 7,200 square feet, requires us to pay 
monthly rent starting at $33,145 per month in July 2001 and escalating annually to a minimum of $47,437 per month in the final year, plus our 
pro rata share of operating expenses and real estate taxes in excess of base year amounts. As part of the lease, we have deposited a U.S. 
Treasury security in escrow for the payment of rent and performance of other obligations specified in the lease. This pledged amount is 
currently $390,000, which will be decreased by $65,000 annually throughout the term of the lease.  

In February 2002, we completed a renovation for approximately $2.6 million to add two chemistry laboratories and purchase additional 

equipment. Currently, there are no plans for additional renovations.  

As a result of the reduction in our staff during July 2002, we have approximately 14,000 square feet of excess space, which is currently 

being subleased.  

At December 31, 2003, we had long-term operating lease obligations, which provide for aggregate minimum payments of $594,897 in 

2004, $605,139 in 2005 and $573,031 in 2006. These obligations include the future rental of our operating facility.  

We plan to finance our needs principally from the following:  

•     our existing capital resources and interest earned on that capital; 

•     payments under collaborative and licensing agreements with corporate partners; and 

•     lease or loan financing and future public or private financing. 

We believe that our available funds will be sufficient to fund our operations at least through 2004. However, this is a forward looking 

statement, and there may be changes that would consume available resources significantly before such time. Our long-term capital 
requirements and the adequacy of our available funds will depend upon many factors, including:  

•     the progress of our research, drug discovery and development programs; 

•     changes in existing collaborative relationships; 

 
 
 
 
 
 
•     our ability to establish additional collaborative relationships; 

•     the magnitude of our research and development programs; 

•     the scope and results of preclinical studies and clinical trials to identify drug candidates; 

•     competitive and technological advances; 

•     the time and costs involved in obtaining regulatory approvals; 

•     the costs involved in preparing, filing, prosecuting, maintaining and enforcing patent claims; 

•     our dependence on others for development and commercialization of our product candidates, and 

•     successful commercialization of our products consistent with our licensing strategy. 

In 2003, our operations consumed approximately $1,000,000 per month, but we expect that our monthly cash used by operations will 

continue to increase for the next several years. During 2004, we plan to both expand our existing clinical programs and initiate clinical 
programs for several new disease indications. These additional trials and the related manufacturing, personnel resources and testing required to 
support these studies will consume significant capital resources and significantly increase our expenses and our net loss. As of December 31, 
2003, we had $25.7 million in cash, cash equivalents and securities. We raised an additional $21.4 million of capital during February 2004 to 
provide the resources necessary to continue the development of our existing programs, while prudently maintaining our cash position. We 
expect our monthly burn rate to  

16  

increase to approximately $2 million by mid-2004, as we get our Phase II trial underway for T-cell leukemia patients. This monthly burn rate 
could increase more as the year progresses and in future years depending on many factors, including our ability to raise additional capital, the 
progress of our BCX-1777 clinical trials for both T-cell leukemia and CTCL, our ability to move BCX-4208 through the preclinical testing 
required to file an IND and begin clinical trials, and the progression of our discovery programs.  

We will be required to raise additional capital to complete the development and commercialization of our current product candidates. 
Additional funding, whether through additional sales of securities or collaborative or other arrangements with corporate partners or from other 
sources, may not be available when needed or on terms acceptable to us. The issuance of preferred or common stock or convertible securities, 
with terms and prices significantly more favorable than those of the currently outstanding common stock, could have the effect of diluting or 
adversely affecting the holdings or rights of our existing stockholders. In addition, collaborative arrangements may require us to transfer certain 
material rights to such corporate partners. Insufficient funds may require us to delay, scale-back or eliminate certain of our research and 
development programs.  

Off-Balance Sheet Arrangements  

As part of our ongoing business, we do not participate in transactions that generate relationships with unconsolidated entities or financial 
partnerships, such as entities often referred to as structured finance or special purpose entities (“SPEs”), which would have been established for 
the purpose of facilitating off-balance sheet arrangements or other contractually narrow or limited purposes. As of December 31, 2003, we are 
not involved in any material unconsolidated SPE or off-balance sheet arrangements.  

Contractual Obligations  

In the table below, we set forth our enforceable and legally binding obligations as of December 31, 2003. Some of the figures we include in 

this table are based on management’s estimates and assumptions about these obligations, including their duration, the possibility of renewal, 
anticipated actions by third parties, and other factors. Because these estimates and assumptions are necessarily subjective, the enforceable and 
legally binding obligations we will actually pay in future periods may vary from those reflected in the table.

We have established various accounting policies that govern the application of accounting principles generally accepted in the United 

States, which were utilized in the preparation of our financial statements. Certain accounting policies involve significant judgments and 
assumptions by management that have a material impact on the carrying value of certain assets and liabilities; management considers such 
accounting policies to be critical accounting policies. The judgments and assumptions used by management are based on historical experience 
and other factors, which are believed to be reasonable under the circumstances. Because of the nature of the judgments and assumptions made 
by management, actual results could differ from these judgments and estimates, which could have a material impact on the carrying values of 
assets and liabilities and the results of operations.  

We believe the following critical accounting policies affect our more significant judgments and estimates used in the preparation of our 

financial statements.  

17  

Revenue Recognition  

The Company recognizes revenue in accordance with SEC Staff Accounting Bulletin No. 104, Revenue Recognition (“SAB No. 104”). 

Research and development revenue on cost-reimbursement agreements is recognized as expenses are incurred, up to contractual limits. 
Research and development fees, license fees and milestone payments are recognized as revenue when the earnings process is complete, the 
Company has no further continuing performance obligations and has completed its performance under the terms of the agreement, in 
accordance with SAB No. 104. License fees and milestone payments received under licensing agreements that are related to future performance 
are deferred and taken into income as earned over the estimated drug development period. Recognized revenues and profit are subject to 
revisions as these contracts or agreements progress to completion. Revisions to revenue or profit estimates are charged to income in the period 
in which the facts that give rise to the revision become known.  

Valuation of Financial Instruments  

We carry our held-to-maturity securities at amortized cost, as adjusted for other-than-temporary declines in market value. In determining if 

and when a decline in market value below amortized cost is other-than-temporary, we evaluate the market conditions and other key measures 
for our held-to-maturity investments. Future adverse changes in market conditions could result in losses or an inability to recover the carrying 
value of the held-to-maturity investments that may not be reflected in an investment’s current carrying value, thereby possibly requiring an 
impairment charge in the future.  

Deferred Taxes  

We have not had taxable income since incorporation and, therefore, we have not paid any income tax. We have deferred tax assets related 

to net operating loss carryforwards and research and development carryforwards, and have recorded a valuation allowance to reduce our 
deferred tax assets to the amount that is more likely than not to be realized. While we have considered future taxable income and ongoing 
prudent and feasible tax planning strategies in assessing the need for the valuation allowance, in the event we were to determine that we would 
be able to realize the deferred tax assets in the future in excess of the net recorded amount, an adjustment to the deferred tax asset would 
increase income in the period such determination was made. Likewise, should we determine that we would not be able to realize all or part of 
the net deferred tax asset in the future, an adjustment to the deferred tax asset would be charged to income in the period such determination was 
made.  

Patents and Licenses  

Patents and licenses are recorded at cost and amortized on a straight-line basis over their estimated useful lives or 20 years, whichever is 

lesser. These costs are reviewed periodically in accordance with Statement of Financial Accounting Standards No. 144, Accounting for the 
Impairment or Disposal of Long-Lived Assets (“Statement No. 144”) to determine any impairment that needs to be recognized.  

An investment in our stock involves a high degree of risk. You should consider carefully the following risks, along with all of the other 
information included in our other filings with the Securities and Exchange Commission, before deciding to buy our common stock. Additional 
risks and uncertainties not currently known to us or that we currently deem to be immaterial may also impair our business operations. If we 
are unable to prevent events that have a negative effect from occurring, then our business may suffer. Negative events are likely to decrease 

Risk Factors  

   
 
our revenue, increase our costs, make our financial results poorer and/or decrease our financial strength, and may cause our stock price to 

decline. In that case, you may lose all or a part of your investment in our common stock.

Risks Relating to Our Business  

We have incurred substantial losses since our inception in 1986, expect to continue to incur such losses and may never be profitable  

Since our inception in 1986, we have not been profitable. We expect to incur additional losses for the foreseeable future, and our losses 
could increase as our research and development efforts progress. As of December 31, 2003, our accumulated deficit was approximately $104.7 
million. To become profitable, we must successfully develop drug candidates, enter into profitable agreements with other parties and our drug 
candidates must receive regulatory approval. We or these other parties must then successfully manufacture and market our drug candidates. It 
could be several years, if ever, before we receive royalties from any future license agreements or revenues directly from product sales.  

If we fail to obtain additional financing, we may be unable to complete the development and commercialization of our product candidates 
or continue our research and development programs.  

To date, we have financed our operations primarily from sale of our equity securities and, to a lesser extent, revenues from collaborations 
and interest. In 2003, our operations consumed approximately $1,000,000 per month, but we expect that our monthly cash used by operations 
will continue to increase for the next several years. During 2004, we plan to both expand our existing clinical programs and initiate clinical 
programs for several new disease indications. These additional trials and the related manufacturing, personnel resources and testing required to 
support these studies will consume significant capital resources and significantly increase our expenses and our net loss.  

As of December 31, 2003, we had $25.7 million in cash, cash equivalents and securities. We raised an additional $21.4 million of capital 
during February 2004 to provide the resources necessary to continue the development of our existing programs, while prudently maintaining 
our cash position. We expect our monthly burn rate to increase to approximately $2 million by mid-2004, as we get our Phase II trial underway 
for T-cell leukemia patients. This monthly burn rate could increase more as the year progresses and in future years depending on many factors 
including, our ability to raise additional capital, the progress of our BCX-1777 clinical trials for both T-cell leukemia and CTCL, our ability to 
move BCX-4208 through the preclinical testing required to file an IND and begin clinical trials, and the progression of our discovery programs. 
Our long-term capital requirements and the adequacy of our available funds will depend upon many factors, including:  

•     the progress of our research, drug discovery and development programs; 

•     changes in existing collaborative relationships; 

•     our ability to establish additional collaborative relationships; 

•     the magnitude of our research and development programs; 

•     the scope and results of preclinical studies and clinical trials to identify drug candidates; 

•     competitive and technological advances; 

•     the time and costs involved in obtaining regulatory approvals; 

•     the costs involved in preparing, filing, prosecuting, maintaining and enforcing patent claims; 

•     our dependence on others for development and commercialization of our product candidates; and 

•     successful commercialization of our products consistent with our licensing strategy. 

We will be required to raise additional capital to complete the development and commercialization of our current product candidates. 
Additional funding, whether through additional sales of securities or collaborative or other arrangements with corporate partners or from other 
sources, may not be available when needed or on terms acceptable to us. The issuance of preferred or common stock or convertible securities, 
with terms and prices significantly more favorable than those of the currently outstanding common stock, could have the effect of diluting or 
adversely affecting the holdings or rights of our existing stockholders. In addition, collaborative arrangements may require us to transfer certain 
material rights to such corporate partners.  

 
   
 
 
 
 
 
 
 
 
 
 
19  

Insufficient funds may require us to delay, scale-back or eliminate certain of our research and development programs.  

We have not commercialized any products or technologies and our future revenue generation is uncertain  

We have not yet commercialized any products or technologies, and we may never be able to do so. Our revenue from collaborative 

agreements is dependent upon the status of our preclinical and clinical programs. If we fail to advance these programs to the point of being able 
to enter into successful collaborations, we will not receive any future milestone or other collaborative payments.  

Any future revenue directly from product sales would depend on our ability to successfully complete clinical studies, obtain regulatory 

approvals, manufacture, market and commercialize any approved drugs.  

If our development collaborations with other parties fail, the development of our drug candidates will be delayed or stopped  

We rely heavily upon other parties for many important stages of our drug development programs, including:  

•     discovery of proteins that cause or enable biological reactions necessary for the progression of the disease or disorder, called enzyme 

targets; 

•     license or design enzyme inhibitors for development as drug candidates; 

•     execution of some preclinical studies and late-stage development for our compounds and drug candidates; 

•     management of our clinical trials, including medical monitoring and data management; 

•     management of our regulatory function; and 

•     manufacturing, sales, marketing and distribution of our drug candidates. 

Our failure to engage in successful collaborations at any one of these stages would greatly impact our business. If we do not license enzyme 

targets or inhibitors from academic institutions or from other biotechnology companies on acceptable terms, our product development efforts 
would suffer. Similarly, if the contract research organizations that conduct our initial or late-stage clinical trials or manage our regulatory 
function breached their obligations to us, this would delay or prevent the development of our drug candidates.  

Even more critical to our success is our ability to enter into successful collaborations for the late-stage clinical development, regulatory 
approval, manufacturing, marketing, sales and distribution of our drug candidates. Our general strategy is to rely upon other parties for all of 
these steps so that we can focus exclusively on the key areas of our expertise. For some smaller niche markets, we may perform these steps 
ourselves and outsource those functions where we do not have the internal expertise. This heavy reliance upon third parties for these critical 
functions presents several risks, including:  

•     these contracts may expire or the other parties to the contract may terminate them; 

•     our partners may choose to pursue alternative technologies, including those of our competitors; 

•     we may have disputes with a partner that could lead to litigation or arbitration; 

•     our partners may not devote sufficient capital or resources towards our drug candidates; and 

•     our partners may not comply with applicable government regulatory requirements. 

Any problems encountered with our current or future partners could delay or prevent the development of our compounds, which would 

severely affect our business, because if our compounds do not reach the market in a timely manner, or at all, we may never receive any 
milestone, product or royalty payments.  

20  

 
 
 
 
 
 
 
 
 
 
 
 
 
If the clinical trials of our drug candidates fail, our drug candidates will not be marketed, which would result in a complete absence of 
product related revenue  

To receive the regulatory approvals necessary for the sale of our drug candidates, we or our licensees must demonstrate through preclinical 

studies and clinical trials that each drug candidate is safe and effective. If we or our licensees are unable to demonstrate that our drug 
candidates are safe and effective, our drug candidates will not receive regulatory approval and will not be marketed, which would result in a 
complete absence of product related revenue. The clinical trial process is complex and uncertain. Because of the cost and duration of clinical 
trials, we may decide to discontinue development of product candidates that are either unlikely to show good results in the trials or unlikely to 
help advance a product to the point of a meaningful collaboration. Positive results from preclinical studies and early clinical trials do not ensure 
positive results in clinical trials designed to permit application for regulatory approval, called pivotal clinical trials. We may suffer significant 
setbacks in pivotal clinical trials, even after earlier clinical trials show promising results. Any of our drug candidates may produce undesirable 
side effects in humans. These side effects could cause us or regulatory authorities to interrupt, delay or halt clinical trials of a drug candidate. 
These side effects could also result in the FDA or foreign regulatory authorities refusing to approve the drug candidate for any targeted 
indications. We, our licensees, the FDA or foreign regulatory authorities may suspend or terminate clinical trials at any time if we or they 
believe the trial participants face unacceptable health risks. Clinical trials may fail to demonstrate that our drug candidates are safe or effective.  

Clinical trials are lengthy and expensive. We or our licensees incur substantial expense for, and devote significant time to, preclinical 

testing and clinical trials, yet cannot be certain that the tests and trials will ever result in the commercial sale of a product. For example, clinical 
trials require adequate supplies of drug and sufficient patient enrollment. Delays in patient enrollment can result in increased costs and longer 
development times. Even if we or our licensees successfully complete clinical trials for our product candidates, we or our licensees might not 
file the required regulatory submissions in a timely manner and may not receive regulatory approval for the drug candidate.  

If we or our licensees do not obtain and maintain governmental approvals for our products under development, we or our partners will not 
be able to sell these potential products, which would significantly harm our business because we will receive no revenue  

We or our licensees must obtain regulatory approval before marketing or selling our future drug products. If we or our licensees are unable 
to receive regulatory approval and do not market or sell our future drug products, we will never receive any revenue from such product sales. In 
the United States, we or our partners must obtain FDA approval for each drug that we intend to commercialize. The FDA approval process is 
typically lengthy and expensive, and approval is never certain. Products distributed abroad are also subject to foreign government regulation. 
The FDA or foreign regulatory agencies have not approved any of our drug candidates. If we or our licensees fail to obtain regulatory approval 
we will be unable to market and sell our future drug products. We have several drug products in various stages of preclinical and clinical 
development; however, we are unable to determine when, if ever, any of these products will be commercially available. Because of the risks 
and uncertainties in biopharmaceutical development, our drug candidates could take a significantly longer time to gain regulatory approval than 
we expect or may never gain approval. If the FDA delays regulatory approval of our drug candidates, our management’s credibility, our 
company’s value and our operating results may suffer. Even if the FDA or foreign regulatory agencies approve a drug candidate, the approval 
may limit the indicated uses for a drug candidate and/or may require post-marketing studies.  

The FDA regulates, among other things, the record keeping and storage of data pertaining to potential pharmaceutical products. We 
currently store most of our preclinical research data at our facility. While we do store duplicate copies of most of our clinical data offsite, we 
could lose important preclinical data if our facility incurs damage. If we get approval to market our potential products, whether in the United 
States or internationally, we will continue to be subject to extensive regulatory requirements. These requirements are wide ranging and govern, 
among other things:  

•     adverse drug experience reporting regulations; 

•     product promotion; 

21  

•     product manufacturing, including good manufacturing practice requirements; and 

•     product changes or modifications. 

Our failure to comply with existing or future regulatory requirements, or our loss of, or changes to, previously obtained approvals, could 
have a material adverse effect on our business because we will not receive product or royalty revenues if we or our licensees do not receive 
approval of our products for marketing.  

In June 1995, we notified the FDA that we submitted incorrect data for our Phase II studies of BCX-34 applied to the skin for cutaneous T-

cell lymphoma and psoriasis. The FDA inspected us in November 1995 and issued us a List of Inspectional Observations, Form FDA 483, 
which cited our failure to follow good clinical practices. The FDA also inspected us in June 1996. The focus was on the two 1995 Phase II 
dose-ranging studies of topical BCX-34 for the treatment of cutaneous T-cell lymphoma and psoriasis. As a result of the investigation, the FDA 
issued us a Form FDA 483, which cited our failure to follow good clinical practices. BioCryst is no longer developing BCX-34; however, as a 

 
 
 
 
 
consequence of these two investigations, our ongoing and future clinical studies may receive increased scrutiny, which may delay the 

regulatory review process.  

We may be unable to establish sales, marketing and distribution capabilities necessary to successfully commercialize products we may 
successfully develop  

We currently have no marketing capability and no direct or third-party sales or distribution capabilities. If we successfully develop a drug 

candidate and decide to commercialize it ourselves rather than relying on third parties, as we currently intend to do in the United States for 
BCX-1777, we may be unable to establish marketing, sales and distribution capabilities necessary to commercialize and gain market 
acceptance for that product.  

If our drug candidates do not achieve broad market acceptance, our business may never become profitable  

Our drug candidates may not gain the market acceptance required for us to be profitable even if they successfully complete initial and final 
clinical trials and receive approval for sale by the FDA or foreign regulatory agencies. The degree of market acceptance of any drug candidates 
that we or our partners develop will depend on a number of factors, including:  

•     cost-effectiveness of our drug candidates; 

•     their safety and effectiveness relative to alternative treatments; 

•     reimbursement policies of government and third-party payers; and 

•     marketing and distribution support for our drug candidates. 

Physicians, patients, payers or the medical community in general may not accept or use our drug candidates even after the FDA or foreign 
regulatory agencies approve the drug candidates. If our drug candidates do not achieve significant market acceptance, we will not have enough 
revenues to become profitable.  

We face intense competition, and if we are unable to compete effectively, the demand for our products, if any, may be reduced  

The biotechnology and pharmaceutical industries are highly competitive and subject to rapid and substantial technological change. We face, 
and will continue to face, competition in the licensing of desirable disease targets, licensing of desirable drug candidates, and development and 
marketing of our product candidates from academic institutions, government agencies, research institutions and biotechnology and 
pharmaceutical companies. Competition may also arise from, among other things:  

•     other drug development technologies; 

•     methods of preventing or reducing the incidence of disease, including vaccines; and 

•     new small molecule or other classes of therapeutic agents. 

Developments by others may render our product candidates or technologies obsolete or noncompetitive.  

22  

We are performing research on or developing products for the treatment of several disorders including T-cell mediated disorders (T-cell 
cancers, psoriasis, and rheumatoid arthritis), cardiovascular, oncology, and hepatitis C, and there are a number of competitors to products in our 
research pipeline. If one or more of our competitors’ products or programs are successful, the market for our products may be reduced or 
eliminated.  

Compared to us, many of our competitors and potential competitors have substantially greater:  

•     capital resources; 

•     research and development resources, including personnel and technology; 

•     regulatory experience; 

 
 
 
 
 
 
 
 
 
 
 
•     preclinical study and clinical testing experience; 

•     manufacturing and marketing experience; and 

•     production facilities. 

Any of these competitive factors could reduce demand for our products.  

If we fail to adequately protect or enforce our intellectual property rights or secure rights to patents of others, the value of those rights 
would diminish  

Our success will depend in part on our ability and the abilities of our licensors to obtain patent protection for our products, methods, 
processes and other technologies to preserve our trade secrets, and to operate without infringing the proprietary rights of third parties. If we or 
our partners are unable to adequately protect or enforce our intellectual property rights for our products, methods, processes and other 
technologies, the value of the drug candidates that we license to derive revenue would diminish. Additionally, if our products, methods, 
processes and other technologies infringe the proprietary rights of other parties, we could incur substantial costs. The U.S. Patent and 
Trademark Office has issued to us a number of U.S. patents for our various inventions and we have in-licensed several patents from various 
institutions. We have filed additional patent applications and provisional patent applications with the U.S. Patent and Trademark Office. We 
have filed a number of corresponding foreign patent applications and intend to file additional foreign and U.S. patent applications, as 
appropriate. We cannot assure you as to:  

•     the degree and range of protection any patents will afford against competitors with similar products; 

•     if and when patents will issue; or 

•     whether or not others will obtain patents claiming aspects similar to those covered by our patent applications. 

If the U.S. Patent and Trademark Office upholds patents issued to others or if the U.S. Patent and Trademark Office grants patent 

applications filed by others, we may have to:  

•     obtain licenses or redesign our products or processes to avoid infringement; 

•     stop using the subject matter claimed in those patents; or 

•     pay damages. 

We may initiate, or others may bring against us, litigation or administrative proceedings related to intellectual property rights, including 

proceedings before the U.S. Patent and Trademark Office. Any judgment adverse to us in any litigation or other proceeding arising in 
connection with a patent or patent application could materially and adversely affect our business, financial condition and results of operations. 
In addition, the costs of any such proceeding may be substantial whether or not we are successful.  

Our success is also dependent upon the skills, knowledge and experience, none of which is patentable, of our scientific and technical 

personnel. To help protect our rights, we require all employees, consultants, advisors and collaborators to enter into confidentiality agreements 
that prohibit the disclosure of confidential information to anyone outside of our company and require disclosure and assignment to us of their 
ideas, developments, discoveries and inventions. These agreements may not provide adequate protection for our trade secrets, know-how or 
other proprietary information in the event of any unauthorized use or disclosure or the  

23  

lawful development by others of such information, and if any of our proprietary information is disclosed, our business will suffer because our 
revenues depend upon our ability to license our technology and any such events would significantly impair the value of such a license.  

If we fail to retain our existing key personnel or fail to attract and retain additional key personnel, the development of our drug candidates 
and the expansion of our business will be delayed or stopped  

We are highly dependent upon our senior management and scientific team, the loss of whose services might impede the achievement of our 

development and commercial objectives. Competition for key personnel with the experience that we require is intense and is expected to 
continue to increase. Our inability to attract and retain the required number of skilled and experienced management, operational and scientific 
personnel, will harm our business because we rely upon these personnel for many critical functions of our business. In addition, we rely on 
members of our scientific advisory board and consultants to assist us in formulating our research and development strategy. All of the members 

 
 
 
 
 
 
 
 
 
 
of the scientific advisory board and all of our consultants are otherwise employed and each such member or consultant may have 

commitments to other entities that may limit their availability to us.  

If users of our drug products are not reimbursed for use, future sales of our drug products will decline  

The lack of reimbursement for the use of our product candidates by hospitals, clinics, patients or doctors will harm our business. Medicare, 

Medicaid, health maintenance organizations and other third-party payers may not authorize or otherwise budget for the reimbursement of our 
products. Governmental and third-party payers are increasingly challenging the prices charged for medical products and services. We cannot be 
sure that third-party payers would view our product candidates as cost-effective, that reimbursement will be available to consumers or that 
reimbursement will be sufficient to allow our product candidates to be marketed on a competitive basis. Changes in reimbursement policies, or 
attempts to contain costs in the health care industry could limit or restrict reimbursement for our product candidates and would materially and 
adversely affect our business, because future product sales would decline and we would receive less product or royalty revenue.  

If we face clinical trial liability claims related to the use or misuse of our compounds in clinical trials, our management’s time will be 
diverted and we will incur litigation costs  

We face an inherent business risk of liability claims in the event that the use or misuse of our compounds results in personal injury or death. 

We have not experienced any clinical trial liability claims to date, but we may experience these claims in the future. After commercial 
introduction of our products we may experience losses due to product liability claims. We currently maintain clinical trial liability insurance 
coverage in the amount of $5.0 million per occurrence and $5.0 million in the aggregate, with an additional $2.0 million potentially available 
under our umbrella policy. The insurance policy may not be sufficient to cover claims that may be made against us. Clinical trial liability 
insurance may not be available in the future on acceptable terms, if at all. Any claims against us, regardless of their merit, could materially and 
adversely affect our financial condition, because litigation related to these claims would strain our financial resources in addition to consuming 
the time and attention of our management.  

If our computer systems fail, our business will suffer  

Our drug development activities depend on the security, integrity and performance of the computer systems supporting them, and the 
failure of our computer systems could delay our drug development efforts. We currently store most of our preclinical and clinical data at our 
facility. Duplicate copies of all critical data are stored off-site in a bank vault. Any significant degradation or failure of our computer systems 
could cause us to inaccurately calculate or lose our data. Loss of data could result in significant delays in our drug development process and 
any system failure could harm our business and operations.  

24  

If, because of our use of hazardous materials, we violate any environmental controls or regulations that apply to such materials, we may 
incur substantial costs and expenses in our remediation efforts  

Our research and development involves the controlled use of 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 some waste 
products. Accidental contamination or injury from these materials could occur. In the event of an accident, we could be liable for any damages 
that result and any liabilities could exceed our resources. Compliance with environmental laws and regulations could require us to incur 
substantial unexpected costs, which would materially and adversely affect our results of operations.  

Risks Relating to Our Common Stock  

Our stock price is likely to be highly volatile and the value of your investment could decline significantly  

The market prices for securities of biotechnology companies in general have been highly volatile and may continue to be highly volatile in 

the future. Moreover, our stock price has fluctuated frequently, and these fluctuations are often not related to our financial results. For the 
twelve months ended December 31, 2003, the 52-week range of the market price of our stock was from $0.82 to $9.41 per share. The following 
factors, in addition to other risk factors described in this section, may have a significant impact on the market price of our common stock:  

•     announcements of technological innovations or new products by us or our competitors; 

•     developments or disputes concerning patents or proprietary rights; 

•     status of new or existing licensing or collaborative agreements; 

•     we or our licensees achieving or failing to achieve development milestones; 

 
 
 
 
 
•     publicity regarding actual or potential medical results relating to products under development by us or our competitors; 

•     regulatory developments in both the United States and foreign countries; 

•     public concern as to the safety of pharmaceutical products; 

•     actual or anticipated fluctuations in our operating results; 

•     changes in financial estimates or recommendations by securities analysts; 

•     economic and other external factors or other disasters or crises; and 

•     period-to-period fluctuations in our financial results. 

Because stock ownership is concentrated, you and other investors will have minimal influence on stockholder decisions  

As of February 27, 2004, our directors, executive officers and some principal stockholders and their affiliates beneficially owned 

approximately 42.7% (directors and officers owned 23.8%) of our outstanding common stock and common stock equivalents. As a result, these 
holders, if acting together, are able to significantly influence matters requiring stockholder approval, including the election of directors. This 
concentration of ownership may delay, defer or prevent a change in our control.  

We have anti-takeover provisions in our corporate charter documents that may result in outcomes with which you do not agree  

Our board of directors has the authority to issue up to 3,178,500 shares of undesignated preferred stock and to determine the rights, 
preferences, privileges and restrictions of those shares without further vote or action by our stockholders. The rights of the holders of any 
preferred stock that may be issued in the future may  

25  

adversely affect the rights of the holders of common stock. The issuance of preferred stock could make it more difficult for third parties to 
acquire a majority of our outstanding voting stock.  

In addition, our certificate of incorporation provides for staggered terms for the members of the board of directors and supermajority 
approval of the removal of any member of the board of directors and prevents our stockholders from acting by written consent. Our certificate 
also requires supermajority approval of any amendment of these provisions. These provisions and other provisions of our by-laws and of 
Delaware law applicable to us could delay or make more difficult a merger, tender offer or proxy contest involving us.  

In June 2002, our board of directors adopted a stockholder rights plan and, pursuant thereto, issued preferred stock purchase rights 

(“Rights”) to the holders of our common stock. The Rights have certain anti-takeover effects. If triggered, the Rights would cause substantial 
dilution to a person or group of persons who acquires more than 15% (19.9% for William W. Featheringill, a Director who currently owns 
more than 13%, but owned more than 15% at the time the Rights were put in place) of our common stock on terms not approved by the board 
of directors.  

We have never paid dividends on our common stock and do not anticipate doing so in the foreseeable future  

We have never paid cash dividends on our stock. We currently intend to retain all future earnings, if any, for use in the operation of our 

business. Accordingly, we do not anticipate paying cash dividends on our common stock in the foreseeable future.

ITEM 7A.  QUANTITATIVE AND QUALITATIVE DISCLOSURES  
ABOUT MARKET RISK.  

The primary objective of our investment activities is to preserve principal while maximizing the income we receive from our investments 

without significantly increasing our risk. We invest excess cash principally in U.S. marketable securities from a diversified portfolio of 
institutions with strong credit ratings and in U.S. government and agency bills and notes, and by policy, limit the amount of credit exposure at 
any one institution. Some of the securities we invest in may have market risk. This means that a change in prevailing interest rates may cause 
the principal amount of the investment to fluctuate. To minimize this risk, we schedule our investments to have maturities that coincide with 
our expected cash flow needs, thus avoiding the need to redeem an investment prior to its maturity date. Accordingly, we believe we have no 
material exposure to interest rate risk arising from our investments. Therefore, no quantitative tabular disclosure is provided.

NOTES TO FINANCIAL STATEMENTS  

Note 1 — Accounting Policies  

The Company  

BioCryst Pharmaceuticals, Inc., a Delaware corporation (the “Company”), is a biotechnology company focused on designing, optimizing 

and developing novel small molecule drugs that block key enzymes essential for cancer, cardiovascular and autoimmune diseases and viral 
infections. The Company has four research projects in different stages of development from early discovery to an ongoing Phase I trial of the 
Company’s most advanced drug candidate, BCX-1777. While the prospects for a project may increase as the project advances to the next stage 
of development, a project can be terminated at any stage of development. Until the Company generates revenues from either a research project 
or an approved product, its ability to continue research projects is dependent upon its ability to raise funds.  

Securities Held-to-Maturity  

The Company is required to classify debt and equity securities as held-to-maturity, available-for-sale or trading. The appropriateness of 

each classification is reassessed at each reporting date. As of December 31, 2003 and 2002, the Company classified all debt and equity 
securities as held-to-maturity. The only dispositions of securities classified as held-to-maturity related to actual maturities or securities called 
prior to their maturity. At December 31, 2003 and 2002, respectively, securities held-to-maturity consisted of $13,791,523 and $22,338,669 of 
U.S. Treasury and Agency securities carried at amortized cost. All of the non-current portions of securities held-to-maturity are U.S. Agency 
securities that mature in 2004-2006. The estimated fair value of all held-to-maturity securities at December 31, 2003 and 2002, respectively, 
was approximately $13,879,086 and $22,640,061. The Company has pledged $600,000 in securities to cover any future draw against its line of 
credit (see Note 5) and has deposited a U.S. Treasury security of $390,000 in escrow for the payment of rent and performance of other 
obligations specified in its lease dated July 12, 2000 (see Note 5). The amount deposited in escrow for the lease decreases $65,000 annually 
throughout the term of the lease.  

Furniture and Equipment  

Furniture and equipment are recorded at cost. Depreciation is computed using the straight-line method with estimated useful lives of five 
and seven years. Laboratory equipment, office equipment, leased equipment and software are depreciated over a life of five years. Furniture 
and fixtures are depreciated over a life of seven years. Leasehold improvements are amortized over the remaining lease period.  

Patents and Licenses  

Patents and licenses are recorded at cost and amortized on a straight-line basis over their estimated useful lives or 20 years, whichever is 

lesser. The Company periodically reviews its patents and licenses for impairment in accordance with Statement of Financial Accounting 
Standards No. 144, Accounting for the Impairment or Disposal of Long-Lived Assets (“Statement No. 144”) to determine any impairment that 
needs to be recognized. During the quarter ended June 30, 2002, the Company abandoned the development of peramivir, its influenza 
neuraminidase inhibitor. As a result, the Company recognized an expense of $373,900 during the quarter ended June 30, 2002 related to the 
patents for the neuraminidase inhibitors, as they no longer have any readily determinable value to the Company.  

Income Taxes  

The liability method is used in accounting for income taxes in accordance with Statement of Financial Accounting Standards No. 109, 
Accounting for Income Taxes (“Statement No. 109”). Under this method, deferred tax assets and liabilities are determined based on differences 
between financial reporting and tax bases of assets and liabilities and are measured using the enacted tax rates and laws that will be in effect 
when the differences are expected to reverse.  

32  

Revenue Recognition  

NOTES TO FINANCIAL STATEMENTS (Continued)  

The Company recognizes revenue in accordance with SEC Staff Accounting Bulletin No. 104, Revenue Recognition (“SAB No. 104”). 

Research and development revenue on cost-reimbursement agreements is recognized as expenses are incurred, up to contractual limits. 
Research and development fees, license fees and milestone payments are recognized as revenue when the earnings process is complete, the 

 
   
 
Company has no further continuing performance obligations and has completed its performance under the terms of the agreement, in 

accordance with SAB No. 104. License fees and milestone payments received under licensing agreements that are related to future performance 
are deferred and taken into income as earned over the estimated drug development period. Recognized revenues and profit are subject to 
revisions as these contracts or agreements progress to completion. Revisions to revenue or profit estimates are charged to income in the period 
in which the facts that give rise to the revision became known. The Company has not received any royalties from the sale of licensed 
pharmaceutical products.  

Net Loss Per Share  

The Company computes net loss per share in accordance with Statement of Financial Accounting Standards No. 128, Earnings per Share . 
Net loss per share is based upon the weighted average number of common shares outstanding during the period. Diluted loss per share includes 
common equivalent shares from unexercised stock options and shares expected to be issued under the Company’s employee stock purchase 
plan. For all periods presented, diluted loss per share does not include the impact of potential common shares outstanding, as the impact of 
those shares is anti-dilutive.  

Statements of Cash Flows  

For purposes of the statements of cash flows, the Company considers cash equivalents to be all cash held in money market accounts or 

investments in debt instruments with maturities of three months or less at the time of purchase.  

Stock-Based Compensation  

The Company accounts for stock-based compensation under Accounting Principles Board Opinion No. 25, Accounting for Stock Issued to 
Employees (“APB No. 25”). Under APB No. 25, the Company’s stock option and employee stock purchase plans qualify as noncompensatory 
plans. Under Financial Accounting Standards Board Interpretation 44, Accounting for Certain Transactions involving Stock Compensation, an 
Interpretation of APB No. 25 , outside directors are considered employees for purposes of applying APB No. 25, if they are elected by the 
shareholders. Consequently, no compensation expense for employees and directors is recognized. Stock issued to non-employees is 
compensatory and compensation expense is recognized under Statement of Financial Accounting Standards No. 123, Accounting for Stock-
Based Compensation (“Statement No. 123”) as amended by Statement of Financial Accounting Standards No. 148 Accounting for Stock-Based 
Compensation—Transition and Disclosure (“Statement No. 148”).  

The following table illustrates the pro forma effect on net loss and net loss per share had the Company applied the fair value recognition 
provisions of Statement No. 123 for the years ended December 31, 2003, 2002 and 2001. See Note 7 for the assumptions used to compute the 
pro forma amounts.

Use of Estimates  

The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires 

management to make estimates and assumptions that affect the amounts reported in the financial statements. Actual results could differ from 
those estimates.

Long-lived assets and certain identifiable intangible assets to be held and used are reviewed for impairment when events or changes in 
circumstances indicate that the carrying amount of such assets may not be recoverable. Determination of recoverability is based on an estimate 
of undiscounted future cash flows resulting from the use of the asset and its eventual disposition. In the event that such cash flows are not 
expected to be sufficient to recover the carrying amount of the assets, the assets are written down to their estimated fair values. Long-lived 
assets and certain identifiable intangible assets to be disposed of are reported at the lower of carrying amount or fair value less cost to sell.  

Note 3 — Concentration of Credit and Market Risk  

The Company invests its excess cash principally in U.S. marketable securities from a diversified portfolio of institutions with strong credit 

ratings and in U.S. government and agency bills and notes and, by policy, limits the amount of credit exposure at any one institution. These 
investments are generally not collateralized and mature within less than three years. The Company has not realized any losses from such 
investments. At December 31, 2003, $4,375,949 was invested in the Merrill Lynch Premier Institutional Fund, which invests primarily in 
commercial paper, U.S. government and agency bills and notes, corporate notes, certificates of deposit and time deposits. The Merrill Lynch 
Premier Institutional Fund is not insured.

                     544,614    
                     845,574    
                 $ 3,692,005    

Rent expense for operating leases was $603,996, $651,506 and $484,227 in 2003, 2002 and 2001, respectively. The commitment for 

operating leases is primarily related to the building lease, which expires in June 2010. The lease, as amended effective July 1, 2001 for 
additional space, requires monthly rents of $33,145 beginning in July 2001 and escalating annually to a minimum of $47,437 per month in the 
final year. The Company has an option to renew the lease for an additional five years at the current market rate on the date of termination and a 
one-time option to terminate the lease on June 30, 2008, subject to a reasonable termination fee.  

On August 5, 2002, at the request of the compensation committee, our Board of Directors approved a reduction in salary of 25% for both 

Dr. Charles E. Bugg, Chairman and Chief Executive Officer and Dr. J. Claude Bennett, President, Chief Operating Officer and Medical 
Director, effective August 1, 2002. In the event of any change of control of the Company, any cumulative salary reductions up to the date of the 
change of control would become due and payable. The monthly amount of the reduction was $14,677 combined. On December 8, 2003, the 
Board of Directors approved the recommendation of the compensation committee to restore their salaries to their previous amounts effective 
January 1, 2004, leaving the cumulative reduction of $249,509 outstanding in the event of a change in control.  

Note 6 — Income Taxes  

The Company has not had taxable income since incorporation and, therefore, has not paid any income tax. Deferred tax assets of 
approximately $46,600,000 and $45,750,000 at December 31, 2003 and 2002, respectively, have been recognized principally for the net 
operating loss and research and development credit carryforwards, and have been reduced by a valuation allowance of $51,800,000 and 
$45,750,000 at December 31, 2003 and 2002, respectively. The valuation allowance will remain at the full amount of the deferred tax asset 
until it is more likely than not that the related tax benefits will be realized.  

At December 31, 2003, the Company had net operating loss and research and development credit carryforwards (“Carryforward Tax 
Benefits”) of approximately $95,300,000 and $9,900,000, respectively, which will expire at various dates beginning in 2005 and continuing 
through 2023. Use of the Carryforward Tax Benefits will be subject to a substantial annual limitation due to the change of ownership 
provisions of the Tax Reform Act of 1986. The annual limitation is expected to result in the expiration of a portion of Carryforward Tax 
Benefits before utilization, which has been considered by the Company in its computations under Statement No. 109. Additional sales of the 
Company’s equity securities may result in further annual limitations on the use of the Carryforward Tax Benefits against taxable income in 
future years.  

Note 7 — Stockholders’ Equity  

In June 2002, the Board of Directors adopted a stockholder rights plan and, pursuant thereto, issued preferred stock purchase rights 

(“Rights”) to the holders of our common stock. The Rights have certain anti-takeover effects. If triggered, the Rights would cause substantial 
dilution to a person or group of persons who  

35  

NOTES TO FINANCIAL STATEMENTS (Continued)  

acquires more than 15% (19.9% for William W. Featheringill, a Director who currently owns more than 13%, but owned more than 15% at the 
time the Rights were put in place) of the Company’s common stock on terms not approved by the Board of Directors. The rights are not 
exercisable until the distribution date, as defined in the Rights Agreement by and between the Company and American Stock Transfer & Trust 
Company, as Rights Agent. The Rights will expire at the close of business on June 24, 2012, unless that final expiration date is extended or 
unless the rights are earlier redeemed or exchanged by the Company.  

Each Right entitles the registered holder to purchase from the Company one one-thousandth of a share of Series B Junior Participating 
Preferred Stock (“Series B”), par value $0.001 per share, at a purchase price of $26.00, subject to adjustment. Shares of Series B purchasable 
upon exercise of the Rights will not be redeemable. Each share of Series B will be entitled to a dividend of 1,000 times the dividend declared 
per share of common stock. In the event of liquidation, each share of Series B will be entitled to a payment of 1,000 times the payment made 
per share of common stock. Each share of Series B will have 1,000 votes, voting together with the common stock. Finally, in the event of any 
merger, consolidation, or other transaction in which shares of common stock are exchanged, each share of Series B will be entitled to receive 
1,000 times the amount received per share of common stock.  

In November 1991, the Board of Directors adopted the 1991 Stock Option Plan (“Plan”) for key employees and consultants of the 

   
 
Company and reserved 500,000 shares of common stock for issuance under the Plan. The Plan was approved by the stockholders on 
December 19, 1991. The original term of the Plan was for ten years and included provisions for issuance of both incentive stock options and 
non-statutory options. The exercise price of options granted under the Plan shall not be less than the fair market value of common stock on the 
grant date. Options granted under the Plan generally vest 25% after one year and monthly thereafter on a pro rata basis over the next three years 
until fully vested after four years and expire ten years after the grant date. Options are generally granted to all full-time employees.  

The Plan was amended and restated in February 1993 to effect the following changes: (i) divide the Plan into two separate incentive 

programs: the Discretionary Option Grant Program and the Automatic Option Grant Program, (ii) increase the number of shares of the 
Company’s common stock available for issuance under the Plan by 500,000 shares and (iii) expand the level of benefits available under the 
Plan. The Board amended the Plan on December 23, 1993 to increase the number of shares issuable under the Plan by 500,000 shares and 
subsequently amended and restated the Plan in its entirety on February 8, 1994. On March 16, 1995, the Board authorized another 500,000 
shares for issuance under the Plan. The Plan was subsequently amended and restated effective March 3, 1997, which amendment and 
restatement included an increase of 1,000,000 shares. The Plan (as so amended and restated) was further amended March 1, 1999 to increase 
the share reserve by 400,000 shares. The Board amended and restated the Plan in its entirety on March 6, 2000, which increased the reserved 
shares by 1,200,000 and extended the term of the Plan for ten years from the date of the amendment. This restatement was approved by the 
Company’s stockholders on May 17, 2000. The automatic option grant program grants options to purchase 10,000 shares to new non-employee 
Board members and an additional 10,000 shares annually over such period of continued service. The vesting and exercise provisions of options 
granted under the Plan are subject to acceleration in the event of certain stockholder-approved transactions, or upon the occurrence of a Change 
in Control as defined by the Plan.

As of December 31, 2003, there were an aggregate of 3,601,747 shares reserved for future issuance under both the Plan and the Employee 

Stock Purchase Plan (“ESPP”) discussed in Note 8.  

The Company follows APB No. 25 in accounting for both the Plan and the ESPP and, accordingly, does not recognize any compensation 
cost related to options granted to employees or non-employee Directors. The Company has adopted the disclosure requirements of Statement 
No. 123, as amended by Statement No. 148. Since Statement No. 123 is only applied to options granted after 1994, the pro forma disclosure 
should not necessarily be considered indicative of future pro forma results when the full four-year vesting (the period in which the 
compensation cost is recognized) is included in the disclosure in 2002. The fair value of each option is estimated on the grant date using the 
Black-Scholes option-pricing method with the following weighted-average assumptions used for grants in 2003, 2002 and 2001, respectively: 
no dividends; expected volatility of 104.4, 104.4 and 92.5 percent; risk-free interest rate of 3.0, 3.6 and 4.6 percent; and expected lives of five 
years. The weighted-average grant-date fair values of options granted during 2003 under the Plan and ESPP were $2.12 and $0.39, 
respectively. The compensation cost recorded for options issued to non-employee consultants was $119,676, $120,190 and $123,289 for the 
years ended December 31, 2003, 2002 and 2001, respectively.

Note 8 — Employee Benefit Plans  

NOTES TO FINANCIAL STATEMENTS (Continued)  

On January 1, 1991, the Company adopted an employee retirement plan (“401(k) Plan”) under Section 401(k) of the Internal Revenue Code 

covering all employees. Employee contributions may be made to the 401(k) Plan up to limits established by the Internal Revenue Service. 
Company matching contributions may be made at the discretion of the Board of Directors. The Company made matching contributions of 
$158,425, $217,097 and $216,897 in 2003, 2002 and 2001, respectively.  

On May 29, 1995, the stockholders approved an employee stock purchase plan (“ESPP”) effective February 1, 1995. On May 15, 2002, the 

stockholders approved an amendment to the ESPP to reserve an additional 200,000 shares and eliminate the January 2005 termination date. 
The Company has reserved a total of 400,000 shares of common stock under the ESPP, of which 182,996 shares remain available for purchase 
at December 31, 2003. Eligible employees may authorize up to 15% of their salary to purchase common stock at the lower of 85% of the 
beginning or 85% of the ending price during the six-month purchase intervals. No more than 3,000 shares may be purchased by any one 
employee at the six-month purchase dates and no employee may purchase stock having a fair market value at the commencement date of 
$25,000 or more in any one calendar year. There were 27,964, 50,127 and 24,122 shares of common stock purchased under the ESPP in 2003, 
2002 and 2001, respectively, at a weighted average price per share of $0.74, $2.45 and $3.87, respectively.  

Note 9 — Collaborative and Other Research and Development Contracts  

The Company granted Novartis Corporation, formerly Ciba-Geigy Corporation (“Novartis”), an option in 1990 to acquire exclusive 
licenses to a class of inhibitors arising from research performed by the Company by February 1991. The option was exercised and a $500,000 
fee was paid to the Company in 1993. Milestone payments are due upon approval of a new drug application. The Company will also receive 
royalties based upon a percentage of sales of any resultant products. Up to $300,000 of the initial fee received is refundable if sales of any 
resultant products are below specified levels and has been recorded as deferred revenue. This agreement has been inactive for several years.  

On November 7, 1991, the Company entered into a joint research and license agreement with The University of Alabama at Birmingham 
(“UAB”). UAB performed specific research on Complement Factors for the Company for a period of approximately three years in return for 
research and license fees. The agreement was replaced by a new agreement on July 18, 1995 granting the Company a worldwide license in 
exchange for funding certain UAB research and sharing in any royalties or sublicense fees arising from the joint research. On November 17, 
1994, the Company entered into another agreement for a joint research and license agreement on influenza neuraminidase granting the 
Company a worldwide license. Under this agreement, the Company funded certain UAB research and UAB shares in any royalties or 
sublicense fees arising from the joint research. The Company completed its research funding required by the agreements for both projects in 
1998, but is still required to pay minimal annual license fees and share any future royalties with UAB.  

On December 23, 2003, the Company transferred to 3-Dimensional Pharmaceuticals, Inc. (3DP), a wholly owned subsidiary of Johnson & 
Johnson, certain rights related to complement system inhibitors discovered during our collaborative research agreement with 3DP, which was 
terminated by BioCryst on October 18, 2003. BioCryst received an initial payment from 3DP, and will receive royalties on any future sales of 
complement inhibitors covered under the assignment.  

   
 
                    
                    
In April 1999, the Company entered into an agreement with Sunol Molecular Corporation. This agreement requires Sunol to conduct 
research and supply the Company with protein targets for drug design to expedite the discovery of new drug candidates designed to inhibit 
tissue factor/factor VIIa for the Company’s cardiovascular program.  

In June 2000, the Company licensed a series of potent inhibitors of purine nucleoside phosphorylase, or PNP, from Albert Einstein College 
of Medicine of Yeshiva University and Industrial Research, Ltd, New Zealand. The lead drug candidate from this collaboration is BCX-1777. 
The Company has the rights to develop and ultimately distribute this, or any other, drug candidate that might arise from research on these 
inhibitors.  

38  

NOTES TO FINANCIAL STATEMENTS (Continued)  

The Company has agreed to pay certain milestone payments for future development of these inhibitors, pay certain royalties on sales of any 
resulting product, and to share in future payments received from other third-party collaborators, if any.  

In June 2000, the Company licensed intellectual property from Emory University related to the hepatitis C polymerase target associated 
with hepatitis C viral infections. Under the terms of the agreement, the research investigators from Emory provide the Company with materials 
and technical insight into the target. The Company has agreed to pay Emory royalties on sales of any resulting product and to share in future 
payments received from other third party collaborators, if any.  

Note 10 — Subsequent Events  

On February 4, 2004, Registrant entered into a Placement Agency Agreement with Leerink Swann & Company in connection with a 
registered direct offering of 3,571,667 shares of its common stock at an offering price of $6.00 per share. The common stock was issued 
pursuant to a prospectus supplement filed with the Securities and Exchange Commission pursuant to Rule 424(b)(2) of the Securities Act of 
1933, as amended, the Securities Act, in connection with a shelf takedown from the Company’s registration statement on Form S-3 (333-
111226), filed on December 16, 2003 and which became effective on January 5, 2004.  

On February 17, 2004, Registrant entered into a Stock Purchase Agreement with Caduceus Private Investments II, LP, Caduceus Private 
Investments II (QP), LP and UBS Juniper Crossover Fund, L.L.C. As part of this agreement, Registrant has granted these investors the right to 
appoint a member to its board of directors effective as of the closing of the offering. On February 18, 2004, the Company announced it had 
completed a $21.4 million registered direct offering of 3,571,667 shares of its common stock to a group of institutional investors.  

Note 11 — Recent Accounting Pronouncements  

In December 2003, the FASB revised SFAS No. 132, “Employers’ Disclosures about Pensions and Other Postretirement Benefits—an 

Amendment of FASB Statements No. 87, 88, and 106”. This statement revises employers’ disclosures about pension plans and other 
postretirement benefit plans to provide more information about pension plan assets, obligations, benefit payments, contributions and net benefit 
cost. This statement retains the disclosures required by the originally issued Statement 132 and requires further disclosures, including 
information describing the types of plan assets, investment strategy, measurement date(s), plan obligations, cash flows, and components of net 
periodic benefit cost recognized during interim periods. SFAS No. 132 (revised 2003) is effective for financial statements with fiscal years 
ending after December 15, 2003, except for disclosure of information about foreign plans and disclosure of estimated future benefit payments, 
which are effective for fiscal years ending after June 15, 2004. The adoption of this statement had no impact on the Company’s financial 
statement disclosures.  

On May 15, 2003, the FASB issued SFAS No. 150, “Accounting for Certain Financial Instruments with Characteristics of both Liabilities 

and Equity,” which establishes standards for classifying and measuring as liabilities certain freestanding financial instruments that embody 
obligations of the issuer and have characteristics of both liabilities and equity. The statement defines an obligation as “a conditional or 
unconditional duty or responsibility on the part of the issuer to transfer assets or to issue its equity shares.” SFAS No. 150 is effective for all 
financial instruments created or modified after May 31, 2003, and otherwise effective at the beginning of the first interim period beginning 
after June 15, 2003. The adoption of this statement did not have a significant impact on the Company’s results of operations or financial 
position.  

On April 30, 2003, the FASB issued Statement of Financial Accounting Standards (“SFAS”) No. 149, “Amendment of Statement 133 on 
Derivative Instruments and Hedging Activities,” in order to provide for more consistent reporting of contracts as either freestanding derivative 
instruments subject to SFAS No. 133 in its entirety, or as hybrid instruments with debt host contracts and embedded derivative features. SFAS 
No. 149 is effective for contracts entered into or modified after June 30, 2003, and for hedging relationships designated after June 30, 2003. 
The adoption of this statement did not have a significant impact on the Company’s results of operations or financial position.  

39  

 
NOTES TO FINANCIAL STATEMENTS (Continued)  

In January 2003, the FASB issued FIN No. 46, “Consolidation of Variable Interest Entities,” (revised December 2003), an interpretation of 
Accounting Research Bulletin 51, “Consolidation of Financial Statements,” which addresses consolidation of variable interest entities (“VIE”) 
by business enterprises. This statement is required in financial statements of public entities that have interests in VIEs or potential VIEs 
commonly referred to as special-purpose entities for periods ending after December 15, 2003. For all other types of entities, application is 
required in financial statements for periods ending after March 15, 2004. The Company believes that the adoption of FIN No. 46 has no impact 
on the results of operations or financial position.  

In December 2002, the Financial Accounting Standards Board (“FASB”) issued Statement of Financial Accounting Standards No. 148, 

Accounting for Stock-Based Compensation — Transition and Disclosure (“Statement No. 148”). This statement addresses transition 
methodologies for companies who intend to adopt the fair valuation methodology of Statement No. 123 for their employee stock-based 
compensation, as well as additional annual and quarterly disclosure requirements for stock-based compensation. The new disclosure rules are 
effective for interim or annual periods ending after December 15, 2002 and are provided in Notes 1 and 7. The Company does not expect there 
to be a material impact on its financial position, results of operations or cash flows as a result of adopting this accounting standard.  

In November 2002, the FASB issued Interpretation No. 45, Guarantor Accounting and Disclosure Requirements for Guarantees, Including 
Indirect Guarantees of Indebtedness of Others (“FIN No. 45”). This interpretation modifies the accounting treatment for certain guarantees and 
is effective for all guarantees issued or modified after December 31, 2002. The new disclosure rules are effective for interim or annual periods 
ending after December 15, 2002. The Company did not experience a material impact on its financial position, results of operations or cash 
flows as a result of adopting this accounting standard.  

In June 2002, the FASB issued Statement of Financial Accounting Standards No. 146, Accounting for Costs Associated with Exit or 
Disposal Activities (“SFAS 146”), which is effective for exit or disposal activities that are initiated after December 31, 2002. The Company 
adopted this statement on July 1, 2002. On July 10, 2002, the Company streamlined its operations, reducing its workforce from 75 employees 
to 45 employees in order to conserve its resources and provide a longer timeframe in which to advance its other programs. As a result of early 
implementation of SFAS 146, the Company recognized all expenses related to this reduction in staff as compensation expense during the third 
quarter of 2002. The total compensation paid in 2002, plus benefits, related to this staff reduction was approximately $325,000.

REPORT OF ERNST & YOUNG, INDEPENDENT AUDITORS  

The Board of Directors  
BioCryst Pharmaceuticals, Inc.  

We have audited the accompanying balance sheets of BioCryst Pharmaceuticals, Inc. as of December 31, 2003 and 2002, and the related 

statements of operations, stockholders’ equity and cash flows for each of the three years in the period ended December 31, 2003. These 
financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on these financial 
statements based on our audits.  

 
   
 
   
 
  
  
  
     
     
     
     
                    
                     
                    
                    
     
                    
                    
                     
                    
                    
     
                    
We conducted our audits in accordance with auditing standards generally accepted in the United States. Those standards require that we 
plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit 
includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes 
assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement 
presentation. We believe that our audits provide a reasonable basis for our opinion.  

In our opinion, the financial statements referred to above present fairly, in all material respects, the financial position of BioCryst 
Pharmaceuticals, Inc. at December 31, 2003 and 2002, and the results of its operations and its cash flows for each of the three years in the 
period ended December 31, 2003, in conformity with accounting principles generally accepted in the United States.

None.  

ITEM 9A.  CONTROLS AND PROCEDURES  

We maintain a set of disclosure controls and procedures that are designed to ensure that information relating to BioCryst Pharmaceuticals, 

Inc. required to be disclosed in our periodic filings under the Securities Exchange Act is recorded, processed, summarized and reported in a 
timely manner under the Securities Exchange Act of 1934. We carried out an evaluation, under the supervision and with the participation of 
management, including our Chief Executive Officer and Chief Financial Officer, of the effectiveness of the design and operation of our 
disclosure controls and procedures. Based upon that evaluation, the Chief Executive Officer and Chief Financial Officer concluded that, as of 
December 31, 2003, the Company’s disclosure controls and procedures are effective to ensure that information required to be disclosed by 
BioCryst in the reports filed or submitted by it under the Securities Exchange Act of 1934, as amended, is recorded, processed, summarized 
and reported within the time periods specified in the SEC’s rules and forms, and include controls and procedures designed to ensure that 
information required to be disclosed by BioCryst in such reports is accumulated and communicated to the Company’s management, including 
the Chairman and Chief Executive Officer and Chief Financial Officer of BioCryst, as appropriate to allow timely decisions regarding required 
disclosure.  

There have been no changes in our internal control over financial reporting that occurred during the quarter ended December 31, 2003 that 

have materially affected, or are reasonably likely to materially affect, BioCryst’s internal control over financial reporting.

members of each class holding office for staggered three-year terms. Dr. Bugg’s, Dr. Montgomery’s, Dr. Gordon’s and Dr. Gee’s terms expire 
at the 2004 annual meeting, at which time Dr. Montgomery and Dr. Gee will not be eligible for re-election due to age limits established by the 
Board of Directors. Mr. Featheringill’s, Mr. Spencer’s and Mr. Sherrill’s terms expire at the 2005 annual meeting, and Dr. Bennett’s, Dr. 
Horovitz’s, and Dr. Steer’s terms expire at the 2006 annual meeting (in all cases subject to the election and qualification of their successors or 
to their earlier death, resignation or removal). At each annual stockholder meeting, the successors to the Directors whose terms expire are 
elected to serve from the time of their election and qualification until the third annual meeting of stockholders following their election and until 
a successor has been duly elected and qualified. However, the number of directors may be decreased at any time either by the stockholders or 
by a majority of the directors then in office, but only to eliminate vacancies existing by reason of the death, resignation, removal or expiration 
of the term of one or more directors. No person shall be elected as a director who has reached his or her 70 th birthday. Persons who are serving 
as directors on the date they reach their 70 th birthday may complete the current term of office of director for which they have been elected but 
shall not be elected to serve another term as director. The provisions of the Company’s Certificate of Incorporation governing the staggered 
Director election procedure can be amended only by a shareholder’s vote of at least 75% of the eligible voting securities. There are no family 
relationships among any of the directors and executive officers of the Company. The Board has by resolution established the number of 
directors of the Company at ten (10) commencing March 8, 2004. Currently, seven of our directors (Messrs. Featheringill, Gee, Gordon, 
Horovitz, Sherrill, Spencer and Steer) are independent as defined by the current Nasdaq rules.  

The Company has an Audit Committee, consisting of Messrs. Featheringill, Gee and Spencer, which is responsible for the review of 
internal accounting controls, financial reporting and related matters. The Audit Committee also recommends to the Board the independent 
accountants selected to be the Company’s auditors and reviews the audit plan, financial statements and audit results. The Board has adopted an 
Amended and Restated Audit Committee Charter that meets all the applicable rules of the Nasdaq National Market and the Securities and 
Exchange Commission. The Audit Committee Charter can be found on the Company’s website at www.biocryst.com. The Audit Committee 
members are “independent” directors as defined by the Nasdaq National Market listing standards in effect as of the date hereof and meet 
Nasdaq’s financial literacy requirements for audit committee members. The Board of Directors has determined that Mr. Featheringill qualifies 
as the “audit committee financial expert”. Upon the expiration of Dr. Gee’s term at the 2004 Annual Meeting, the Board has made a 
determination to recruit another outside Board member who would also meet  

44  

the requirements of a “financial expert”. After this additional Board member has been recruited and adequately understands the Company’s 
financial records, Mr. Featheringill has determined that he will step down from the Audit Committee.  

The Company also has a Compensation Committee consisting of Messrs. Featheringill, Gee and Spencer. The Compensation Committee is 

 
 
responsible for the annual review of officer compensation and other incentive programs and is authorized to award options under the 
Company’s Stock Option Plan. The Board has adopted a Compensation Committee Charter that meets all the applicable rules of the Nasdaq 
National Market and the Securities and Exchange Commission. The Charter can be found on the Company’s website at www.biocryst.com. 
The Compensation Committee members are “independent” directors as defined by the Nasdaq National listing standards in effect as of the date 
hereof.  

The Company has a Nominating Committee comprised of all independent directors with terms not expiring in the current year. The current 
members of the committee are Messrs. Featheringill, Horovitz, Sherrill, Spencer, and Steer. The Nominating Committee nominates persons for 
election or re-election as directors. The Board has adopted a Nominating Committee Charter that meets all the applicable rules of the Nasdaq 
National Market and the Securities and Exchange Commission. The Nominating Committee has established procedures/qualifications for 
selecting nominees and will consider nominees recommended in writing, including biographical information and personal references, by 
stockholders. All submissions by shareholders should be sent directly to the Chairman of the Board, Dr. Bugg at the corporate address.  

The Company has adopted a Code of Business Conduct (the “Code”) applicable to all employees, including executive officers, and all
