After oral administration, both ASC10 and molnupiravir are rapidly and completely converted in vivo into the same active drug ASC10-A, also known as β-D-N4-hydroxycytidine (NHC) or EIDD-1931. ASC10 was discovered and developed in-house.
With this issue notification, Ascletis has become the first Chinese biotech company which has been granted a patent by the USPTO for its in-house developed oral viral polymerase inhibitor and its derivatives. The patent issuance will extend commercial protection for ASC10 and its derivatives, and their uses until 2042.

ASC10 has a broad spectrum of antiviral activity, and is expected to unleash more potential in addressing the challenges of multiple viruses. I’m looking forward to advancing the clinical studies to benefit more patients.” said Dr. Jinzi J. Wu, Founder, Chairman and CEO of Ascletis.
