Statement of Work

BioCryst Pharmaceuticals Contract HHSO100201500007C

BCX4430 NDA Enabling CMC and Non-Clinical Toxicology Studies

PREAMBLE

Independently and not as an agent of the Government, the Contractor shall furnish all the necessary services, qualified personnel, material, equipment, and facilities, not otherwise provided by the Government as needed to perform the Statement of Work submitted in response to the BARDA Broad Agency Announcement (BAA) CBRN-BAA-10-100-SOL-00013.

The Government reserves the right to modify the milestones, progress, schedule, budget, or deliverables to add or delete deliverables, process, or schedules if the need arises. Because of the nature of this research and development (R&D) contract and the complexities inherent in this and prior programs, at designated milestones the Government will evaluate whether work should be redirected, removed, or whether schedule or budget adjustments should be made.

Overall Objectives and Scope

The overall objective of this contract is to advance the development of BCX4430, a novel small molecule nucleoside with broad spectrum antiviral activity being developed for diseases caused by RNA pathogens. BCX4430, an inhibitor of viral RNA – dependent RNA polymerase (RdRp), is the lead compound in our broad-spectrum antiviral program to meet the need for a parenteral, direct-acting antiviral medical countermeasure (MCM) having efficacy across multiple viruses. The scope of work for this contract includes preclinical and manufacturing development activities that fall into the following areas: manufacturing of clinical trial material, manufacturing process improvements and development, non-clinical toxicology studies; and all associated regulatory, quality assurance, management, and administrative activities. The proposed activities take into account the Ebola virus disease (EVD) outbreak in West Africa. The R&D effort will contribute toward an NDA filing for BCX4430. Overall, this Statement of Work (SOW) focuses on:

| • | Drug substance (DS) and drug product (DP) manufacturing process development activities that will be conducted at US based facilities, which will result in the ability to consistently produce high quality, GMP compliant material and deliver drug supply that could be available for deployment as a medical countermeasure during the Ebola crisis and support future clinical and non-clinical studies

| • | Nonclinical development activities to advance the intramuscular (IM) and intravenous (IV) formulation through NDA-enabling toxicology including * * * and * * * studies in the * * * and * * *
