Contractual Statement of Work


1.	PREAMBLE

Independently and not as an agency of the Government, the Contractor shall be required to 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-00012.

In accordance with FAR 52.243-2, Changes-Cost Reimbursement (Alt. V), the Government reserves the right to modify the milestones, progress, schedule, budget, or 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.

1.1 Overall Objectives and Scope

The overall objective of this contract is to advance the development of CMX-001 as a broad-spectrum therapeutic antiviral for the treatment of smallpox infections and dsDNA viruses. The scope of work for this contract includes preclinical, clinical and manufacturing development activities that fall into the following areas: non-clinical efficacy studies; clinical activities; manufacturing activities; and all associated regulatory, quality assurance, management, and administrative activities. The Research and Development (R&D) effort for the antiviral will progress in specific stages that cover the base performance segment and four (4) option segments as specified in this contract. The Contractor must complete specific tasks required in each of the five discrete work segments. The scope of work has been broken into the following five phases which are discrete work segments:


I.	[...***...]


II.	[...***...]


III.	[...***...]
