About this opportunity
The National Institute of Mental Health is modifying two existing contracts on a sole-source basis to expand clinical research support under the National NeuroHIV Tissue Consortium program using fiscal year 2026 appropriated funds. Contract modifications increase UCSD's contract 75N95023C00014 by $269,941 (Option Period Three through August 22, 2027) and Washington University's contract 75N95024C00027 by $543,301.63 (Option Period Two through September 22, 2027), for a combined modification value of $813,242.63.
The justification cites FAR 6.103-1 (sole source), emphasizing that continuity with current contractors is essential to maintain seamless operations, avoid duplication of costs, and prevent unacceptable delays in ongoing clinical research focused on mental health and neurocognitive outcomes in people with HIV. Both contracts were initially awarded through full and open competition (UCSD base period August 2023–August 2024; WashU base period September 2024–September 2025). A SAM.gov notice published August 3, 2026, yielded no responses. Fair and reasonable pricing will be determined using historical pricing data. NIMH plans a competitive recompetition for fiscal year 2028 with expanded market research to maximize competition. Work involves participant recruitment, longitudinal follow-up, biospecimen collection and storage, and neuropsychiatric assessment coordinated with the NNTC Data Coordinating Center.
