A clinical study of people with HIV-1 who have not taken antiretroviral therapy, one group will start treatment with a combination of doravirine and Islatravir compared to a different group that will start treatment with bictegravir/emtricitabine/tenofovir alafenamide

Trial design

CTIS Part I — objectives, methods, condition coding

Main objective

Scope: Pharmacogenomic, Pharmacokinetic, Safety, Therapy, Efficacy, Pharmacogenetic

1. To evaluate the antiretroviral activity of DOR/ISL compared to BIC/FTC/TAF, as assessed by the percentage of participants with HIV-1 RNA <50 copies/mL at Week 48.
2. To evaluate the safety and tolerability of DOR/ISL compared with BIC/FTC/TAF as assessed by review of the accumulated safety data through Week 48.

Secondary objectives 6

1. To evaluate the antiretroviral activity of DOR/ISL compared with BIC/FTC/TAF, as assessed by the percentage of participants with HIV-1 RNA <50 copies/mL at Week 96
2. To evaluate the antiretroviral activity of DOR/ISL compared with BIC/FTC/TAF, as assessed by the percentage of participants with HIV-1 RNA <200 copies/mL at Week 48 and Week 96
3. To evaluate the immunologic effect of DOR/ISL compared with BIC/FTC/TAF, as assessed by the mean change from baseline in CD4+ T-cell count at Week 48 and Week 96
4. To evaluate the development of viral drug resistance in participants who receive DOR/ISL and in those who receive BIC/FTC/TAF
5. To evaluate the effect of DOR/ISL compared with BIC/FTC/TAF on weight, as assessed by the mean change from baseline to Week 48 and Week 96
6. To evaluate the safety and tolerability of DOR/ISL compared with BIC/FTC/TAF as assessed by review of the accumulated safety data through study duration

Eligibility criteria

Principal inclusion / exclusion criteria as submitted by sponsor

Inclusion criteria 3

1. Is an individual ≥18 years of age of any sex/gender who is HIV-1 positive with plasma HIV-1 RNA ≥500 copies/mL at screening
2. Is naïve to antiretroviral therapy (ART) defined as having received no prior therapy with any antiretroviral agent following a diagnosis of HIV-1 infection
3. Female is not a participant of childbearing potential (POCBP); or if a POCBP, is not pregnant or breastfeeding, and is willing to use an acceptable contraceptive method or abstain from heterosexual intercourse for study duration

Exclusion criteria 7

1. Has HIV-2 infection
2. Has hypersensitivity or other contraindication to any of the components of the study interventions as determined by the investigator
3. Has a diagnosis of an active AIDS-defining opportunistic infection within 30 days prior to screening
4. Has active hepatitis B infection (defined as hepatitis B surface antigen [HBsAg]-positive or HBV deoxyribonucleic acid [DNA]-positive).
5. Has chronic hepatitis C virus (HCV) infection (detectable HCV ribonucleic acid [RNA])
6. 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
7. Has a history or current evidence of any condition (including active tuberculosis infection), therapy, laboratory abnormality, or other circumstance (including drug or alcohol use or dependence) that might, in the opinion of the investigator, confound the results of the study or interfere with the participant’s participation for the full duration of the study, such that it is not in the best interest of the participant to participate

4. Change from baseline in cluster of differentiation 4+ (CD4+) T-cells at Week 48
5. Change from baseline in CD4+ T-cells at Week 96
6. Incidence of viral drug resistance
7. Change from baseline in body weight at Week 48
