A Study in Healthy Participants to Assess the Effect of Darunavir, Emtricitabine, and Tenofovir Alafenamide in the Presence of Cobicistat When Administered as a Fixed Dose Combination (Darunavir/Cobicistat/Emtricitabine/Tenofovir Alafenamide) Compared to the Co-administration of the Separate Agents

Overview

The purpose of the study is to evaluate the single-dose pharmacokinetics (PK) and pivotal bioequivalence of 3 compounds Darunavir (DRV), emtricitabine (FTC), and tenofovir alafenamide (TAF) in the presence of cobicistat (COBI) when administered as an fixed dose combination (FDC) (Darunavir/Cobicistat/Emtricitabine/Tenofovir Alafenamide [D/C/F/TAF]) compared to the co-administration as the separate commercial formulations (DRV and F/TAF and COBI), under fed conditions, in healthy participants.

Clinical Trial Outcome Measures

Primary Measures

  • Maximum Observed Analyte Concentration (Cmax) of Darunavir, Cobicistat, Emtricitabine and Tenofovir Alafenamide
    • Time Frame: Up to 72 hours post-dose
    • Cmax is the maximum observed analyte concentration.
  • Area Under the Analyte Concentration-time Curve from time Zero to Last Quantifiable time (AUC[0-last]) of Darunavir, Cobicistat, Emtricitabine and Tenofovir Alafenamide
    • Time Frame: Up to 72 hours post-dose
    • AUC(0-last) is the area under the analyte concentration-time curve of from time 0 to the time of the last measurable (non-below quantification limit [non-BQL]) concentration, calculated by linear-linear trapezoidal summation.

Secondary Measures

  • Area Under the Analyte Concentration-time Curve From Time Zero to Infinite Time (AUC[0-infinity]) of Darunavir, Cobicistat, Emtricitabine and Tenofovir Alafenamide
    • Time Frame: Up to 72 hours post-dose
    • AUC (0-infinity) is the area under the analyte concentration-time curve from time zero to infinite time, calculated as the sum of AUC(0-last) and C(last)/lambda(z); wherein AUC(0-last) is area under the analyte concentration-time curve from time zero to last quantifiable time, C(last) is the last observed measurable concentration, and lambda(z) is elimination rate constant.
  • Cmax of Cobicistat
    • Time Frame: Up to 72 hours post-dose
    • Cmax is the maximum observed analyte concentration of Cobicistat.
  • AUC(0-last) of Cobicistat
    • Time Frame: Up to 72 hours post-dose
    • AUC(0-last) is the area under the analyte concentration-time curve of from time 0 to the time of the last measurable (non-BQL) concentration, calculated by linear-linear trapezoidal summation.
  • Number of Participants with Adverse Events
    • Time Frame: From signing of the Informed consent form (ICF) till the last study-related activity (up to 10 weeks)
    • An adverse event is any untoward medical event that occurs in a participant administered an investigational product, and it does not necessarily indicate only events with clear causal relationship with the relevant investigational product.

Inclusion Criteria

  • Must be healthy on the basis of physical examination, medical history, vital signs, and electrocardiogram (ECG) performed at screening. If there are abnormalities, the participant may be included only if the investigator judges the abnormalities or deviations from normal to be not clinically significant. This determination must be recorded in the participant's source documents and initialed by the investigator – Participant must be healthy on the basis of clinical laboratory test performed at screening. If the results of the serum chemistry panel, hematology, or urinalysis are outside the normal reference ranges, the participant may be included only if the investigator judges the abnormalities or deviations from normal to be not clinically significant. – A woman (of childbearing potential) must have a negative highly sensitive serum beta-human chorionic gonadotropin (beta-hCG) pregnancy test, 4 days or less before dosing of the first treatment period – Contraceptive use by men or women should be consistent with local regulations regarding the use of contraceptive methods for participant participating in clinical studies – A woman must agree not to donate eggs (ova, oocytes) for the purposes of assisted reproduction during the study and for at least 90 days after receiving the last dose of study drug – During the study and for a minimum of at least 90 days after receiving the last dose of study drug, a male participant must wear a condom when engaging in any activity that allows for passage of ejaculate to another person (male subject should also be advised of the benefit for a female partner to use a highly effective method of contraception as condom may break or leak); must agree not to donate sperm for the purpose of reproduction. – Must be willing and able to adhere to the prohibitions and restrictions specified in the study protocol Exclusion Criteria:
