Clinical Trials

Numerous clinical trials spanning Phase 1 through Phase 4 evaluate Azvudine for indications such as COVID-19, chronic hepatitis B, HIV-infection/AIDS, and pharmacokinetic profiles in healthy individuals and patients with renal insufficiency. Spearheaded by diverse sponsors including Henan Genuine Biotech Co., Ltd., Peking Union Medical College Hospital, and Shanghai Henlius Biotech, these studies range in recruitment status from completed and actively recruiting to not yet recruiting and unknown. Notably, late-phase trials have assessed the drug's safety and therapeutic efficacy in COVID-19 and chronic hepatitis B cohorts.

Compliance for Clinical Use

Mechanism and Biochemical Profile

As a nucleoside reverse transcriptase inhibitor, Azvudine incorporates into viral nucleic acid chains, thereby inhibiting reverse transcriptase activity and blocking downstream viral genomic replication. This halting of viral synthesis suppresses viral load and prevents viral propagation, demonstrating therapeutic clinical relevance in the treatment of COVID-19, chronic hepatitis B, and HIV infections.
