Drug class/category

Integrase strand transfer inhibitor (INSTI); precursor of the third-generation INSTI VH4524184 (VH-184)

Summary

VH5356136 is an investigational compound from ViiV Healthcare related to VH4524184 (VH-184), ViiV's 3rd generation INSTI. The trial entry NCT07822477 describes VH4524184 as its parent compound and measures VH4524184 as a metabolite of VH5356136, which is consistent with a prodrug of VH-184; ViiV has not publicly confirmed the chemistry, mechanism or intended dosing interval, and the moldecule is not apparent in the company pipeline yet. VH-184 itself has shown an enhanced in vitro resistance profile versus second-generation INSTIs, and its long-acting injectable formulations (SC/IM) were reported at CROI 2026 to support monthly/two-monthly (formulation A) or six-monthly (formulation B) dosing. VH5356136 is entering a first-time-in-human, single-dose phase 1 study of two formulations in adults without HIV (planned start November 2026).

More details

The study aims to evaluate the safety, tolerability and pharmacokinetic (PK) properties of a single dose of VH5356136 in adult participants without human immunodeficiency virus (HIV). This study will be conducted following the availability of initial safety and PK clinical data from formulation of the parent drug VH4524184.

Purpose

A Study to Investigate Safety, Tolerability and Pharmacokinetics of VH5356136 in Adult Participants Without HIV
