A Study to Evaluate the Pharmacokinetics and Safety of Azvudine Tablets in Healthy Adult Subjects and Healthy Elderly Subjects

Phase 1

Completed

• Conditions: Healthy
• Interventions: Drug: Azvudine tablets

• Registration Number: NCT06991634
• Lead Sponsor: Henan Genuine Biotech Co., Ltd.

Brief Summary

Azvudine (FNC), a nucleoside reverse transcriptase inhibitor, make itself a better candidate to be co-formulated in other anti-HIV therapies, thus to improve patient's compliance. FNC is a broad-spectrum RNA virus inhibitor that inhibits the novel coronavirus RNA-dependent RNA polymerase (RdRp). This is an open, parallel design clinical study to evaluate the pharmacokinetics and safety of Azvudine tablets in healthy adult and elderly subjects in single and multiple doses. The study is divided into two stages. In the first stage, after a single oral administration of 5 mg of Azvudine tablets, biological sample collection and safety examination were performed. After completing the first phase of the test, the subjects can enter the second phase of the test after a 3-day washout period, and received oral administration of 5 mg Azvudine tablets once a day for 7 consecutive days, biological samples were collected and safety tests were performed.
