Ascletis Pharma Inc. (HKG: 1672<\/a>) announced that its wholly-owned subsidiary Ascletis Pharmaceuticals Co., Ltd has entered into a five-year license and supply agreement with Pfizer Investment Co., Ltd, the China unit of US-based Pfizer Inc.

This includes elderly patients (above 60) and those with risk factors such as chronic kidney disease, diabetes, cardiovascular disease, and chronic lung disease. Paxlovid was conditionally approved for marketing in China in February 2022 and has since been approved or authorized for conditional or emergency use in approximately 70 markets globally.<\/p>\n\n\n\n

Ritonavir: Pharmacokinetic Booster and Market Position<\/strong>
Ritonavir is a pharmacokinetic booster used in combination with multiple oral antiviral drugs targeting viral proteases.
