The National Institute on Drug Abuse (NIDA) intends to solicit proposals from qualified businesses to provide in vitro metabolism and permeability determinations for its medications development program in support of the Division of Pharmacotherapies and Medical Consequences of Drug Abuse (DPMCDA). The in vitro metabolism studies for this contract typically include metabolite profiling for interspecies comparison using hepatocytes and microsomes, CYP 450 phenotyping reaction, CYP 450 inhibition, and CYP 450 induction for potential medications. It may also include evaluation of in vitro metabolism by other systems such as hepatic cytosol, hepatic mitochondrial fraction, or Phase II reactions (glucuronidation, sulfation, acetylation, methylation, conjugation with glutathione, conjugation with amino acids). This contract may also provide structure identification of major metabolites by mass spectrometry or nuclear magnetic resonance (NMR). Additional in vitro studies include determination of intestinal and blood-brain barrier permeabilities of new compounds. 

In order to handle substances under the Controlled Substances Act of 1970, it is mandatory that offerors possess a DEA Registration for Chemical Analysis or Research Registration for Schedules II to V and demonstrate the capability to obtain a DEA registration for Schedule I controlled substances.

NIDA anticipates one (1) Indefinite Delivery Indefinite Quantity (Task Order) type contract will be awarded. NIDA plans to issue fixed price task orders.
