Brief summary

The purpose of this study is to evaluate effect of single and repeated doses of darunavir (DRV) in combination with cobicistat (DRV/COBI) and with ritonavir (DRV+rtv) on the pharmacokinetics of single dose dabigatran etexilate (measured in plasma as free and total dabigatran) when co-administered in healthy participants.

Interventions

DRUGDabigatran Etexilate

Participants will receive single dose of dabigatran etexilate orally.

DRUGDRV/COBI

Participants will receive oral tablet of fixed dose combination (FDC) containing darunavir (DRV)/ cobicistat (COBI).

DRUGRitonavir

Participants will receive ritonavir orally.

DRUGDarunavir

Participants will receive Darunavir orally.

Inclusion criteria

* Must have a body mass index (BMI) (weight in kilogram \[kg\]/height\^2 in square meters \[m\^2\] ) between 18.0 and 30.0 kg/m\^2 (inclusive) and body weight not less than 50.0 kg * Must sign an informed consent form (ICF) indicating that they understand the purpose of, and procedures required for, the study and are willing to participate in the study * A woman must have a negative highly sensitive serum beta human chorionic gonadotropin (beta hCG) pregnancy test at screening, on Day -1 (only if the test performed at screening was greater than \[\>\] 4 days before dosing), and at the end of the study * 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 * Must be willing and able to adhere to the prohibitions and restrictions specified in this protocol * A male participant must agree not to donate sperm for the purpose of reproduction during the study and for a minimum 90 days after receiving the last dose of study drug

Exclusion criteria

* Clinically significant abnormalities during physical examination, vital signs, or 12 lead - electrocardiogram (ECG) at screening 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 * With a history of clinically significant drug allergy such as, but not limited to, sulfonamides and penicillins, or drug allergy diagnosed in previous studies with experimental drugs * Has donated blood or blood products or had substantial loss of blood (more than 500 milliliter \[mL\]) within 3 months before the first administration of study drug or intention to donate blood or blood products during the study * Has received an investigational drug or used an investigational medical device within 60 days before the first intake of study drug

Design outcomes

Primary

MeasureTime frameDescription
Maximum Observed Analyte Concentration (Cmax) of Dabigatran Etexilate (Free and Total)Up to Day 18Cmax is the maximum observed analyte concentration.
Area Under the Plasma Concentration-Time Curve from Time Zero to the Time of Last Quantifiable Concentration (AUC[0-last]) of Dabigatran Etexilate (Free and Total)Up to Day 18AUC(0-last) is the Area under the curve (AUC) from time 0 to the time of last measurable (non-below quantification limit) concentration, calculated by linear-linear trapezoidal summation.
Area Under the Plasma Concentration-Time Curve from Time Zero to Infinite Time (AUC0-infinity) of Dabigatran Etexilate (Free and Total)Up to Day 18AUC(0-infinity) is defined as area under the plasma concentration-time curve from time zero to infinite time.

Secondary

MeasureTime frameDescription
Number of Participants with Adverse Events (AEs) as a Measure of Safety and TolerabilityFrom signing of the ICF up to end of study (up to 8 weeks)An AE is any untoward medical occurrence in a participant participating in a clinical study that does not necessarily have a causal relationship with the pharmaceutical/biological agent under study.
