Frequently asked questions about Varegacestat

What is Varegacestat?

Varegacestat is an investigational small molecule developed by Immunome, Inc. (ticker IMNM). It is being studied in the gastrointestinal therapeutic area and is currently in Phase 1 clinical development. Its specific disease indications have not been disclosed. Varegacestat is also referred to as Varegacestat Reference Formulation.

What does Varegacestat target?

Varegacestat targets gamma-secretase, an enzyme belonging to the -stat target class. Gamma-secretase is a multi-subunit protease complex involved in cleaving transmembrane proteins. By targeting this enzyme, Varegacestat acts as a small molecule inhibitor of gamma-secretase activity.

Who makes Varegacestat?

Varegacestat is being developed by Immunome, Inc., which trades on the Nasdaq under the ticker symbol IMNM. Immunome is the sponsor of the clinical program evaluating Varegacestat in Phase 1 studies.

What phase is Varegacestat in?

Varegacestat is in Phase 1 clinical development. It is an investigational drug and has not been approved by the FDA. Five Phase 1 trials have been conducted or are ongoing, with one currently active and four completed, enrolling a total of 115 participants.

What clinical trials is Varegacestat in?

Varegacestat has been evaluated in five Phase 1 trials. These include NCT07610005, a recruiting relative bioavailability and bioequivalence study; NCT06855264, a completed cardiac liability study; NCT06845852, a completed mass balance study; and NCT06841315, a completed hepatic impairment study. All were conducted in the United States.

Is Varegacestat the same as Varegacestat Reference Formulation?

Yes. Varegacestat Reference Formulation is an alternative name for Varegacestat. Both names refer to the same investigational small molecule developed by Immunome, Inc. for the gastrointestinal therapeutic area.
