An investigational new drug (IND) application for a COVID-19 treatment has been approved by the China National Medical Products Administration (NMPA).

The  application is for ASC10, an oral inhibitor drug candidate targeting RNA-dependent RNA polymerase (RdRp) that targets the COVID-19 virus.

China’s first

Ascletis is China’s first biotech company to obtain IND approvals of an oral RdRp inhibitor from both the NMPA and the U.S. Food and Drug Administration (FDA).

ASC10 is an oral double prodrug, which has a new and differentiated chemical structure from the single prodrug molnupiravir. After oral administration, both ASC10 and molnupiravir are rapidly and completely converted in vivo into the same active metabolite ASC10-A, also known as β-D-N4-hydroxycytidine (NHC).

ASC10 was discovered and developed in-house. Ascletis has filed multiple patent applications for ASC10 and its use globally. ASC10 oral tablet formulation for the clinical study was developed with in-house proprietary technology of Ascletis.

Clinical development

Ascletis said it is communicating with regulatory authorities to explore the possibility of further accelerating the clinical development of ASC10.
