Overview
Brief Summary
The study will evaluate the safety, tolerability, pharmacokinetics, and antiretroviral activity of a single dose of ulonivirine in antiretroviral therapy (ART)-naive, HIV-1 infected participants. The hypothesis tested in the study is that at a safe and well-tolerated dose, ulonivirine has superior antiretroviral activity to a historical placebo control, as measured by change from baseline in plasma HIV-1 ribonucleic acid (RNA) at 168 hours postdose.

- •History of cancer, with the exceptions of 1) adequately-treated non-melanomatous skin carcinoma or carcinoma in situ of the cervix, 2) other malignancies which have been successfully treated \>=10 years before screening, or 3) participants who are highly unlikely to sustain a recurrence for the duration of the study
- •History of significant multiple and/or severe allergies, or has had an anaphylactic reaction or significant intolerability to drugs or food

Arms & Interventions
Panel A: Ulonivirine 600 mg
Single oral dose of ulonivirine 600 mg (supplied as 10 mg and 100 mg tablets) administered after an overnight fast
Intervention: Ulonivirine
Panel B: Ulonivirine 150 mg
Single oral dose of ulonivirine 150 mg (supplied as 10 mg and 100 mg tablets) administered after an overnight fast
Intervention: Ulonivirine
Panel C: Ulonivirine <=600 mg
Single oral dose of ulonivirine \<=600 mg mg (supplied as 10 mg and 100 mg tablets) administered after an overnight fast. Inclusion of Panel C in the study, and the dose selected, will be decided pending evaluation of results for Panels A and B.
Intervention: Ulonivirine
