VH3739937 Low Dose Group

Participants received a low dose of VH3739937 as loading Dose 1 (LD1) on Day 1, followed by a once-daily (QD) dose of VH3739937 as maintenance Dose 1 (MD1) from Days 2 through 7, where MD1 was lower than LD1. On Day 8, all participants transitioned to standard-of-care (SOC) combination antiretroviral therapy (cART) and continued study assessments through Day 25.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

* Participants who are overtly healthy (other than HIV infection) as determined by the Investigator or medically qualified designee based on a medical evaluation including medical history, physical examination, laboratory tests, and cardiac monitoring
