Study Summary

This trial will compare the safety and efficacy of switching to a new drug regimen (MK-8591A) versus continuing the current drug regimen (BIC/FTC/TAF) in HIV-1 infected individuals who are currently virally suppressed. The primary hypothesis is that the new drug regimen will be at least as effective as the current drug regimen in maintaining viral suppression.

Who is the study for?
This trial is for HIV-1 positive adults with a stable viral load under 50 copies/mL on BIC/FTC/TAF therapy for at least 3 months, without past treatment failure. Women must not be pregnant or breastfeeding and either not of childbearing potential or using contraception. Exclusions include recent participation in other studies, resistance to DOR, intent to conceive, HIV-2 infection, active hepatitis or certain cancers within the last 5 years.Check my eligibility
What is being tested?
The study tests if switching from BIC/FTC/TAF to a new drug combo (Doravirine/Islatravir) maintains low HIV levels. Participants are randomly assigned to continue their current meds or switch to the new one. The main goal is seeing if the new combo works just as well by checking virus levels after 48 weeks.See study design
What are the potential side effects?
Potential side effects aren't specified here but typically may include gastrointestinal issues like nausea and diarrhea, headaches, fatigue, and possible allergic reactions among others commonly seen with antiretroviral drugs.
