A Clinical Study of the Interactions Between Azvudine Tablets (FNC) and Dolutegravir Sodium Tablets (DTG)

A Clinical Study of the Interactions Between Azvudine Tablets (FNC) and Dolutegravir Sodium Tablets (DTG)

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 FNC and Dolutegravir Sodium Tablets in healthy subjects. This is a single-center, randomized, open-label, three-cycles, three-treatment crossover clinical trial. Subjects was administered orally for 5 consecutive days each cycle, and the washout period between each cycle was 7 days. Biological sample collection and safety examination were performed.

Inclusion Criteria:

1. Healthy subjects aged ≥ 18 years old and ≤ 45 years old, regardless of gender;
2. Body mass index (BMI) within the range of 19.0-26.0 (including the critical value) (BMI = weight (kg) / height 2 (m2)), the weight of men should be ≥ 50.0kg, and the weight of women should be ≥ 45.0kg;
3. Those who had no birth plan within 2 weeks before screening and within 6 months after the end of the trial and agree to take effective non-drug contraceptive measures during the trial;

6. Individuals with a history of substance abuse within the past 12 months or who tested positive for addictive substances prior to enrollment;
7. Individuals who underwent surgery within the past 3 months, especially those who had had surgeries that would affect drug absorption, distribution, metabolism, or excretion, or those planning to undergo surgery during the study;
8. Individuals who had taken any medication that interacts with the trial drug in the 30 days prior to screening, such as strong CYP3A inhibitors (e.g., clarithromycin, indinavir, itraconazole, etc.);
9. Individuals with a history of cardiovascular, liver, kidney, pulmonary, gastrointestinal, neurological diseases, especially any surgical conditions or disorders that might affect drug absorption, distribution, metabolism, and excretion, or any surgical conditions or disorders that might pose hazards to participants;
