Summary

Dolutegravir (DTG), a human immunodeficiency virus (HIV)-1 integrase inhibitor (INI), and Rilpivirine (RPV), a non-nucleoside HIV-1 reverse transcriptase inhibitor (NNRTI), are each approved in the United States (US), European Union, and other countries for the treatment of HIV-1 infection. JULUCA is a combination of Dolutegravir and Rilpivirine indicated for the treatment of HIV-1 infection in antiretroviral (ARV) experienced adult subjects who are switching from their current antiretroviral treatment to the 2-drug combination. Although, the pharmacokinetics (PK), safety and tolerability of DTG/RPV (50 milligram [mg]/25mg) fixed-dose combination (FDC) tablets have been extensively studied, these parameters have not been assessed exclusively in Japanese subjects. This study will evaluate the pharmacokinetics, safety and tolerability of a single dose DTG/RPV 50 mg/25 mg FDC in a healthy adult Japanese population to support a post-approval commitment for DTG/RPV 50 mg/25 mg FDC in Japan.

  • A female subject is eligible to participate if she is not pregnant or breastfeeding, and not a woman of childbearing potential (WOCBP)
  • The investigator is responsible for review of medical history, menstrual history, and recent sexual activity to decrease the risk for inclusion of a woman with an early undetected pregnancy
  • Subjects capable of giving signed informed consent, which includes compliance with the requirements and restrictions listed in the informed consent form (ICF) and in this protocol

Exclusion Criteria

  • Subjects with history of current cardiovascular, respiratory, hepatic, renal, gastrointestinal, endocrine, hematological, or neurological disorders capable of significantly altering the absorption, metabolism, or elimination of drugs; constituting a risk when taking the study intervention or interfering with the interpretation of data
  • Subjects with abnormal blood pressure (as determined by the investigator)
  • Subjects with alanine transaminase (ALT) >1.5 times upper limit of normal (ULN)
  • Subjects with bilirubin >1.5 times ULN (isolated bilirubin >1.5 times ULN is acceptable if bilirubin is fractionated and direct bilirubin 460 millisecond (msec)(Based on the average of the 12-Lead-electrocardiogram (ECG) triplicate readings obtained at Screening) (Note: The QTc is the QT interval corrected for heart rate according to Fridericia's formula (QTcF), and/or another method, machine-read or manually over-read. The specific formula that will be used to determine eligibility and discontinuation for an individual subject should be determined prior to initiation of the study. In other words, several different formulae cannot be used to calculate the QTc for an individual subject and then the lowest QTc value used to include or discontinue the subject from the trial)
  • Subjects with past or intended use of over-the-counter or prescription medication including herbal medications within 7 days (or 14 days if the drug is a potential enzyme inducer) or 5 half-lives (whichever is longer) prior to dosing. Acetaminophen, at doses of 14 units for males or >7 units for females. One unit is equivalent to 8 gram of alcohol: a half-pint (approximately 240mL) of beer, 1 glass (125mL) of wine or 1 (25mL) measure of spirits
  • Subjects with sensitivity to heparin or heparin-induced thrombocytopenia
  • Subjects with sensitivity to any of the study interventions, or components thereof, or drug or other allergy that, in the opinion of the investigator or medical monitor, contraindicates participation in the study
