Bioequivalence Study of ADC118 Tablets in Healthy Chinese Volunteers Under Fasting Conditions

This clinical trial aims to evaluate the bioequivalence of a single oral dose of the test drug ADC118 tablets compared with the reference drugs (ACC017 tablets and emtricitabine/tenofovir alafenamide fumarate tablets [II]) under fasting conditions in healthy adult Chinese participants. It will also assess the safety of the test drug. The main questions it aims to answer include:

Is the rate and extent of absorption of the test drug ADC118 tablets equivalent to that of the reference drugs?

What adverse events will participants experience while taking the study drugs? Researchers will compare the pharmacokinetic profiles of ADC118 tablets with those of the two reference drugs after a single dose.

Participants will:

Be randomly assigned to one of three treatment sequences (TRR, RTR, or RRT)

In each of the three periods, after an overnight fast of at least 10 hours, take a single dose of the test drug (T) or the reference drug (R) with 240 mL of warm water

Refrain from drinking water (except for the 240 mL taken with the drug) for 1 hour before and after dosing, and not eat any food for 4 hours after dosing

Complete blood sample collection and safety assessments according to the protocol This study plans to enroll 48 healthy participants. It is a single-center, randomized, open-label, three-period crossover trial.

Primary outcomes

  1. PK Parameter: Cmax

    Time frame: Day 1 (pre-dose) through Day 6 (120 hours post-dose) of each treatment period

    Cmax is defined as the maximum observed plasma concentration of the drug, obtained directly from the concentration-time data, following a single oral dose of the test or reference product under fasting conditions.

  2. PK Parameter: AUC0-t

    Time frame: Day 1 (pre-dose) through Day 6 (120 hours post-dose) of each treatment period

    AUC0-t is defined as the area under the plasma concentration-time curve from time zero to the time of the last measurable plasma concentration, calculated using the linear trapezoidal rule.

  3. PK Parameter: AUC0-∞

    Time frame: Day 1 (pre-dose) through Day 6 (120 hours post-dose) of each treatment period

    AUC0-∞ is defined as the area under the plasma concentration-time curve from time zero extrapolated to infinity, calculated as AUC0-t + Clast/λz, where Clast is the last measurable plasma concentration and λz is the terminal elimination rate constant.

Secondary outcomes

  1. PK Parameter: Tmax

    Time frame: Day 1 (pre-dose) through Day 6 (120 hours post-dose) of each treatment period

    Tmax is defined as the time to reach the maximum observed plasma concentration (Cmax)
