GMP [14C] API Manufacturing

Moravek is licensed by the California Department of Public Health, Food and Drug Branch, for the preparation, and 14C or 3H labeling of active pharmaceutical ingredients (API) for clinical trials. In addition, Moravek is allowed to handle schedule I-V classified compounds under DEA authority.

Moravek can prepare 14C and 3H radiolabeled APIs for Phases 0, I and II, mass balance and microdosing (Phase 0 and Phase I) studies.

Moravek is able to perform GMP synthesis, purification, testing, and QA release in compliance with FDA Phase 0, I and II GMP guidance (IQCH Q7A Section 19).

Radiolabeled APIs produced or purified under GMP conditions are analyzed on qualified analytical instrumentation and are supplied with a complete batch record, which includes documentation of the synthetic, purification and analytical processes from start to finish.

Finished 14C and 3H radiolabeled APIs can be sent to a contract research laboratory (CRO), to carry out the GMP procedures for the preparation of investigational medicinal product (IMPs).

GMP work is carried out in one of our three state-of-the-art certified GMP suites.

APIs are analyzed using qualified HPLC and MS instrumentation and NMR.
