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 a clinical study to evaluate the Interactions between Azvudine Tablets (FNC) and Rilpivirine Tablets (RPV) in healthy subjects. This is a single-center, randomized, open-label, three-cycles, three-treatment crossover clinical trial. Subjects was administered orally for 10 consecutive days each cycle, and the washout period between each cycle was 14 days. Biological sample collection and safety examination were performed.
