Proof-of-Concept Trial of VH4524184 (VH-184), a Third-Generation Integrase Strand Transfer Inhibitor (CROI 2025) - "An exposure-response relationship was established comparable to the maximum effect with other INSTIs. These results support further development of VH-184 as the core agent in a complete long-acting regimen for the treatment of HIV-1."

Phase 1 study of VH4524184 (VH-184), a new third-generation integrase strand transfer inhibitor (INSTI) with a unique resistance profile (AIDS 2024) - "We present the pharmacokinetics, safety, and in vitro resistance profile of VH-184. A double-blind, randomized, placebo-controlled, phase 1, first-time-in-human (FTIH) study evaluated oral VH-184 in healthy adults administered as single ascending doses (10-460 mg; part 1), multiple ascending doses (160-480 mg) for 14 days with concomitant midazolam (part 2), and as a single dose (100 mg) under fasted and fed conditions (part 3)...VH-184 demonstrated potent in vitro antiviral activity against dolutegravir-selected INSTI-resistant isolates (Figure). FTIH study results helped characterize VH-184 pharmacokinetics and indicate that VH-184 does not inhibit or induce CYP3A4 and has a moderate positive food effect. FTIH study results helped characterize VH-184 pharmacokinetics and indicate that VH-184 does not inhibit or induce CYP3A4 and has a moderate positive food effect. The in vitro resistance profile of VH-184 is distinct from prior INSTIs, retaining antiviral activity..."

In vitro characterization of VH4524184 (VH-184, S-365598), a new third-generation integrase strand transfer inhibitor (INSTI) with a unique resistance profile (AIDS 2024) - "The in vitro antiviral potency of VH-184 is comparable to DTG and CAB and its resistance profile is distinct from prior INSTIs. VH-184 is a third generation INSTI candidate with a superior resistance profile compared to DTG and CAB. These data support its further development for HIV-1 treatment."
