Frequently asked questions about INCB161734

What is INCB161734 used for?

INCB161734 is an investigational small molecule being studied for the treatment of solid tumors with the KRAS G12D mutation, including advanced or metastatic solid tumors and previously untreated metastatic pancreatic ductal adenocarcinoma. It is also being studied in healthy participants to assess its pharmacokinetics.

What does INCB161734 target?

INCB161734 targets KRAS G12D, a specific mutation in the KRAS gene. This mutation is associated with certain solid tumors, and the drug is designed to act on this molecular target.

Who makes INCB161734?

INCB161734 is being developed by Incyte Corporation, a biopharmaceutical company traded on the NASDAQ under the ticker symbol INCY.

What phase is INCB161734 in?

INCB161734 is in Phase 1 clinical development. It is being evaluated in early-stage trials for solid tumors and healthy participants. It is not yet approved by the FDA and remains investigational.

What clinical trials is INCB161734 in?

INCB161734 is being studied in three clinical trials. NCT06179160 is a Phase 1 study in advanced or metastatic solid tumors with KRAS G12D mutation. NCT07018635 is a completed Phase 1 study in healthy participants. NCT07522073 is a Phase 3 study in previously untreated KRAS G12D-mutated metastatic pancreatic ductal adenocarcinoma.

Is INCB161734 the same as any other drug?

No alternative names for INCB161734 have been disclosed. It is referred to solely by its code name INCB161734 in clinical trial registries and by its developer, Incyte Corporation.
