Study of Lenacapavir, Teropavimab, and Zinlirvimab Versus Cabotegravir and Rilpivirine in Virologically Suppressed Adults With HIV-1 on Oral Daily Antiretroviral Therapy
A Phase 3, Randomized, Open-label Study to Evaluate the Efficacy and Safety of Switching to Long-acting Antiretroviral Therapy of Broadly Neutralizing Antibodies Teropavimab and Zinlirvimab in Combination With the Capsid Inhibitor Lenacapavir Twice-Yearly Versus Cabotegravir and Rilpivirine Every 8 Weeks in Virologically Suppressed Adults With HIV-1 on Oral Daily Antiretroviral Therapy
The goal of this clinical study is to compare how effective a long-acting injectable treatment of lenacapavir (LEN), teropavimab (TAB), and zinlirvimab (ZAB) versus (CAB) and rilpivirine (RPV) injections given every 8 weeks in adults with HIV-1 whose virus is well controlled on daily oral treatment, after 1 year (52 weeks) of the treatment.
The primary objective of this study are to evaluate the efficacy of switching to the regimen of LEN, TAB, and ZAB versus switching to CAB and RPV in virologically suppressed people with HIV-1 (PWH) as determined by the proportion of participants with HIV-1 RNA ≥ 50 copies/mL at Week 52.

Beskrivelse
Key Inclusion Criteria:
Human immunodeficiency virus type 1 (HIV-1) susceptibility results from screening meeting specific criteria:
1) Proviral phenotypic susceptibility to both TAB and ZAB by the investigational protocol-defined assay at screening.
- At least 1 documented HIV-1 RNA level measured between 6 months and 12 months (+2 months) prior to screening. This and any other HIV-1 RNA measurements documented in this period must be < 50 copies/mL (undetectable HIV-1 RNA level according to the local assay being used if the limit of detection is ≥ 50 copies/mL). A single virologic elevation of ≥ 50 copies/mL and < 400 copies/mL (transient detectable viremia or "blips") prior to screening are acceptable if the subsequent plasma HIV-1 RNA level is < 50 copies/mL.
A plasma HIV-1 RNA test < 50 copies/mL (undetectable HIV-1 RNA level according to the local assay being used if the limit of detection is ≥ 50 copies/mL) within the last 6 months prior to screening.
1) If > 1 plasma HIV-1 RNA measurements in the last 6 months prior to screening are available, all must be < 50 copies/mL (undetectable HIV-1 RNA level according to the local assay being used if the limit of detection is ≥ 50 copies/mL).
On a stable oral ARV therapy (ART) for ≥ 6 months prior to screening.
- A change in ART regimen ≥ 3 months prior to the screening visit for reasons other than virologic failure (VF) (eg, tolerability, simplification, drug-drug interaction profile) is allowed; individuals with a change in ART regimen ≥ 3 months prior to screening must have been on the regimen for ≥ 3 months prior to screening, and all HIV-1 RNA measurements in that period must be < 50 copies/mL. There are no permitted changes to ART regimens between screening and Day 1.
Key Exclusion Criteria:
- History of an opportunistic infection or illness indicative of Stage 3 HIV disease.

- Treatment with immunosuppressant therapies (eg, corticosteroids, immunoglobulins, and other immune- or cytokine-based therapies) within 4 weeks of screening (with the exception of a single short course of corticosteroids lasting ≤ 7 days) or have a comorbid condition with an anticipated need ongoing immunosuppressive treatment during the study.
- Hepatitis C virus (HCV) antibody positive and HCV RNA detectable.
Chronic hepatitis B virus (HBV) infection, as determined by either:
- Positive HBV surface antigen and negative HBV surface antibody, regardless of HBV core antibody status, at the screening visit.
- Positive HBV core antibody and negative HBV surface antibody, regardless of HBV surface antigen status, at the screening visit.
- Severe renal impairment-estimated glomerular filtration rate < 30 mL/min according to the Cockcroft-Gault formula.
- Abnormal electrocardiogram (ECG) at the screening visit that is clinically significant, as determined by the investigator.
Any of the following laboratory values at screening:

- Direct bilirubin > 1.5 x ULN.
- Platelets < 50,000/mm^3.
- Hemoglobin < 8.0 g/dL.

Eksperimentel: Treatment Group 1: Lenacapavir(LEN)+ Teropavimab(TAB)+ Zinlirvimab (ZAB)
Participants will receive oral LEN 600 mg, subcutaneous (SC) LEN 927 mg, and intravenously (IV) infusions of TAB and ZAB on Day 1. Participants will self-administer oral LEN 600 mg on Day 2. Every 26 weeks, participants will receive SC LEN and IV infusions of TAB and ZAB up to Week 92. After Week 92, eligible participants will have an option to continue LEN + TAB + ZAB in the extension phase, until completion of the extension phase, permanently discontinuing the extension phase or the extension is discontinued at the sponsor's sole discretion, whichever occurs first. |
