Brief summary
The purpose of this Phase 2b study is to evaluate the efficacy and therapeutic window of chronically dosed VH4011499 paired with an integrase strand transfer inhibitor (INSTI). This study will explore 4 different regimens of VH4011499 when paired with cabotegravir (CAB) as an initial two-drug regimen.

|---|---|---|
| Number of participants with plasma HIV-1 RNA <50 copies/mL as per FDA snapshot algorithm | At Month 13 and Month 25 | — |
| Number of participants with plasma HIV-1 RNA <50 copies/mL as per observed data | At Month 7, Month 13 and Month 25 | — |
| Change from baseline (Day 1) in cluster of differentiation (CD) 4+ T-cell count | At Month 7, Month 13 and Month 25 | — |
| Number of participants with injection site reaction adverse events of special interest (ISR AESIs) by grade | Through Month 7, Month 13 and Month 25 | The ISR AESIs will be graded using the Division of Acquired Immunodeficiency Syndrome (DAIDS) grading table Version 2.1, where Grade 1 = mild, Grade 2 = moderate, Grade 3 = severe, Grade 4 = potentially life-threatening. |
| Duration of ISR AESIs by grade | Through Month 7, Month 13 and Month 25 | The ISR AESIs will be graded using the DAIDS grading table Version 2.1, where Grade 1 = mild, Grade 2 = moderate, Grade 3 = severe, Grade 4 = potentially life-threatening. |
| Number of participants with serious adverse events (SAEs) by grade | Through Month 7, Month 13 and Month 25 | An SAE is defined as any untoward medical occurrence that, at any dose, resulted in death, was life-threatening, required hospitalization or prolongation of existing hospitalization, resulted in disability/incapacity, caused a congenital anomaly/birth defect, or was any other situation identified according to medical or scientific judgment. The SAEs will be graded using the DAIDS grading table Version 2.1, where Grade 1 = mild, Grade 2 = moderate, Grade 3 = severe, Grade 4 = potentially life-threatening, Grade 5 = death. |
| Number of participants with adverse events (AEs) leading to study treatment discontinuation, by grade | Through Month 7, Month 13 and Month 25 | The AEs leading to treatment discontinuation will be graded using the DAIDS grading table Version 2.1, where Grade 1 = mild, Grade 2 = moderate, Grade 3 = severe, Grade 4 = potentially life-threatening, Grade 5 = death. |
| Plasma concentrations of VH4011499 | Through Months 7, 13 and 25 | — |
