Study Summary

The primary objectives of this study are to evaluate the antiretroviral activity of a switch to Doravirine/Islatravir (DOR/ISL) compared with continued Bictegravir/Emtricitabine/Tenofovir Alafenamide (BIC/FTC/TAF) at Week 48; and to evaluate the safety and tolerability of a switch to DOR/ISL compared with continued BIC/FTC/TAF, through Week 48. The primary hypotheses are that (1) DOR/ISL is non-inferior to continued BIC/FTC/TAF, as assessed by the percentage of participants with HIV-1 ribonucleic acid (RNA) ≥50 copies/mL at Week 48, with a margin of 4 percentage points used to define non-inferiority; and (2) DOR/ISL is superior to BIC/FTC/TAF, as assessed by the percentage of participants with HIV-1 RNA ≥50 copies/mL at Week 48.

Primary Outcome

HIV-1 RNA levels in blood samples taken at each visit were measured with a reliable lower limit of quantification of \<50 copies/mL. The percentage of participants with HIV-1 RNA ≥50 copies/mL at Week 48 is presented using the FDA Snapshot missing data approach.
