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.

The key inclusion and exclusion criteria include but are not limited to the following: Inclusion Criteria: * Is HIV-1 positive with plasma HIV-1 RNA \<50 copies/mL * Has been receiving BIC/FTC/TAF therapy with documented viral suppression (HIV-1 RNA \<50 copies/mL) for ≥3 consecutive months prior to providing documented informed consent and has no history of prior virologic treatment failure on any past or current regimen * Female is not a participant of childbearing potential (POCBP); or if a participant of childbearing potential, not pregnant or breastfeeding, and is willing to use an acceptable contraceptive method or abstain from heterosexual intercourse for study duration Exclusion Criteria: * Has HIV-2 infection * Has a diagnosis of an active acquired immunodeficiency syndrome (AIDS)-defining opportunistic infection within 30 days prior to screening * Has active hepatitis B virus (HBV) infection * Has chronic hepatitis C virus (HCV) infection with laboratory values consistent with cirrhosis * Has a history of malignancy ≤5 years prior to providing documented informed consent except for adequately treated basal cell or squamous cell skin cancer, in situ cervical cancer, or cutaneous Kaposi's sarcoma * Is taking or is anticipated to require systemic immunosuppressive therapy, immune modulators, or strong and moderate cytochrome P450 3A (CYP3A) inducers * Has a documented or known virologic resistance to DOR * Has taken long-acting HIV therapy at any time (e.g., cabotegravir, lenacapavir) * Is currently participating in or has participated in a clinical study and received (or is receiving) an investigational compound or device from 45 days prior to Day 1 through the study treatment period except those currently enrolled in the comparator arm of an ongoing DOR/ISL study

Primary outcome measure(s)

  • Percentage of Participants With Human Immunodeficiency Virus Type 1 (HIV-1) Ribonucleic Acid (RNA) ≥50 Copies/mL at Week 48 — Week 48
    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.
  • Percentage of Participants Who Experience Adverse Events (AEs) Through Week 48 — Up to Week 48
    An AE was defined as any untoward medical occurrence in a clinical study participant, temporally associated with the use of study intervention, whether or not considered related to the study intervention. The percentage of participants who experienced at least one AE is reported.
  • Percentage of Participants Who Discontinue Study Intervention Due to AEs Through Week 48 — Up to Week 48
    An AE was defined as any untoward medical occurrence in a clinical study participant, temporally associated with the use of study intervention, whether or not considered related to the study intervention. The percentage of participants who discontinued study intervention due to an AE is reported.
