Ascletis owns the authorized ritonavir oral tablet in China, which passed bioequivalence study. The Company’s ritonavir oral tablet was approved in September, 2021 by China National Medical Products Administration (NMPA). As a pharmacokinetic booster of multiple antiviral protease inhibitors, a low dose ritonavir oral tablet (100 mg) is a component of oral direct-acting antiviral drug Paxlovid (Nirmatrelvir+ritonavir). The Company applied the sophisticated formulation technology to significantly increase the human bioavailability of ritonavir which has a very poor solubility and successfully achieved human bioequivalence with the ritonavir oral tablets produced by the Originator, AbbVie.
