Clinical trial NCT04236453: 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
Official title: A Single-Dose, Open-Label, Randomized, Replicate Crossover Pivotal Bioequivalence Study in Healthy Subjects to Assess the Bioequivalence of Darunavir 675 mg, Emtricitabine 200 mg, and Tenofovir Alafenamide 10 mg in the Presence of Cobicistat 150 mg When Administered as a Fixed Dose Combination (Darunavir/Cobicistat/Emtricitabine/Tenofovir Alafenamide) Compared to the Co-administration of the Separate Agents (Darunavir, Cobicistat, and Emtricitabine/Tenofovir Alafenamide), Under Fed Conditions

Brief summary: 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.


Eligibility criteria: 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:

* Has history or current clinically significant medical illness including (but not limited to) cardiac arrhythmias or other cardiac disease, hematologic disease, coagulation disorders (including any abnormal bleeding or blood dyscrasias), lipid abnormalities, significant pulmonary disease (including bronchospastic respiratory disease), diabetes mellitus, hepatic or renal insufficiency (for example, estimated creatinine clearance below less than \[\<\] 90 milliliter per minute \[mL/min\] at screening), gastrointestinal disease (such as significant diarrhea, gastric stasis, or constipation that in the investigator's opinion could influence drug absorption or bioavailability), thyroid disease, neurologic or psychiatric disease, infection, or any other illness that the investigator considers should exclude the participant or that could interfere with the interpretation of the study results
* Had one or more of the laboratory abnormalities at screening as outlined in the protocol by the Division of Acquired immunodeficiency syndrome (DAIDS) Table for Grading the Severity of Adult and Pediatric Adverse Events and in accordance with the normal ranges of the clinical laboratory
* Clinically significant abnormalities during physical examination, vital signs, or 12 lead electrocardiogram (ECG) at screening or at admission to the study center as deemed appropriate by the investigator
* With any history of clinically significant skin disease such as, but not limited to, dermatitis, eczema, drug rash, psoriasis, food allergy, or urticaria
* Has a history of drug or alcohol abuse according to Diagnostic and Statistical Manual of Mental Disorders (5th edition) (DSM-V) criteria within 1 year before screening or positive test result(s) for alcohol and/or drugs of abuse (such as hallucinogens, barbiturates, opiates, opioids, cocaine, cannabinoids, amphetamines, methadone, benzodiazepines, methamphetamine, tetrahydrocannabinol, phencyclidine, and tricyclic antidepressants) either at screening or on Day 1 of each treatment period
