Ascletis Announces IND Filing of Oral RdRp Inhibitor ASC10 for COVID-19 Accepted by China NMPA

Hangzhou and Shaoxing, China, Aug. 4, 2022-- Ascletis Pharma Inc. (HKEX: 1672, “Ascletis”) today announces that its Investigational New Drug (IND) application of ASC10, an oral inhibitor drug candidate targeting RNA-dependent RNA polymerase (RdRp) for COVID-19 has been accepted by China National Medical Products Administration (NMPA).

ASC10 is an orally bioavailable 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 by Ascletis.
