A Phase 2b Study Evaluating VH4011499 Capsid Inhibitor Long-Acting Injectable Plus Cabotegravir in Treatment Naïve Adults (CINERGY) (CINERGY)

September 6, 2026 updated by: ViiV Healthcare

A Phase 2b Randomized, Open-Label Active Controlled Study Evaluating the Safety and Efficacy of 2-drug Injectable Regimens of VH4011499 Plus Cabotegravir in Treatment Naïve Viremic Adult Participants With HIV-1 (CINERGY)

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.
