Frequently asked questions about VH4011499

What is VH4011499 used for in HIV infections?

VH4011499 is an investigational small molecule being developed for the treatment of HIV infections. It is a capsid inhibitor and is being studied as a long-acting injectable, including in combination with cabotegravir, in treatment-naive adults living with HIV. It is not yet approved for any use.

What does VH4011499 target?

VH4011499 targets the HIV capsid protein, making it a capsid inhibitor. By acting on the capsid, the drug interferes with steps in the HIV replication cycle. It is being developed as a long-acting injectable formulation, which is the focus of its Phase 2b study in treatment-naive adults.

Who is developing VH4011499?

VH4011499 is being developed by GSK plc, which trades under the ticker GSK. GSK is running the clinical program for the drug, including a Phase 2b study of the long-acting injectable given with cabotegravir and several earlier-phase studies in healthy participants.

What phase is VH4011499 in?

VH4011499 is in Phase 2 development. The lead study is a Phase 2b trial of the long-acting injectable plus cabotegravir in treatment-naive adults with HIV. Earlier Phase 1 studies have been completed, and the drug is investigational, meaning it has not been approved by the FDA.

What clinical trials is VH4011499 in?

VH4011499 has been studied in four trials. These include the Phase 2b CINERGY study, NCT07816250, in treatment-naive adults with HIV; a Phase 1 safety and pharmacokinetics study, NCT06724640; a completed food-effect study, NCT06368986; and a completed first-time-in-human study, NCT05393271.

Is VH4011499 the same as VH4011499 low dose?

Yes. VH4011499 low dose, VH4011499 Dose A, and VH4011499 low dose Injection are alternative names for the same investigational compound, VH4011499. These labels refer to dose levels or formulations of the drug rather than to a different asset, so searches using those terms point to the same GSK program.
