GMP [14C] API Manufacturing

Licensed by the Food and Drug Branch of the California Department of Public Health, Moravek holds the ability to prepare 14C or 3H labeled active pharmaceutical ingredients (API) for clinical trials. We are also permitted to handle schedule I-V classified compounds under DEA authority.


GMP 14C API Manufacturing

Moravek is a leader in API GMP solutions, with the ability to prepare 14C and 3H radiolabeled APIs for Phases 0, I, and II mass balance and microdosing (Phase 0 and Phase I) studies. We perform GMP synthesis, purification, testing, and QA release in compliance with FDA Phase 0, I, and II GMP guidance (ICH Q7 Section XIX). In addition, we provide secure GMP storage conditions for our customers’ compounds.

In our GMP synthesis, purification, testing, and QA release processes, we analyze radiolabeled APIs that have been produced or purified under GMP conditions. These compounds 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.

From synthesis to top-notch GMP storage conditions, all of Moravek’s work is carried out in 1 of our 4 certified GMP suites. APIs are analyzed using qualified HPLC, NMR, and MS instrumentation.

Production of APIs includes, but is not limited to:
