Frequently asked questions about GNS561

What is GNS561 used for?

GNS561 is an investigational small molecule being studied for the treatment of cholangiocarcinoma, a cancer of the bile ducts. It is being evaluated specifically in patients with advanced KRAS mutated cholangiocarcinoma, in combination with trametinib. GNS561 is not approved and remains in clinical development.

Who is developing GNS561?

GNS561 is being developed by Genfit SA, which trades on the NYSE under the ticker GNFT. The company sponsors the clinical program evaluating GNS561 in combination with trametinib for advanced KRAS mutated cholangiocarcinoma.

What phase is GNS561 in?

GNS561 is in Phase 1 clinical development. The program consists of a single active trial, and no trials have been completed. GNS561 is investigational and has not been approved by the FDA for any indication.

What clinical trial is GNS561 in?

GNS561 is being studied in NCT05874414, titled Combination of GNS561 and Trametinib in Patients With Advanced KRAS Mutated Cholangiocarcinoma. The Phase 1 trial is currently recruiting and plans to enroll 98 patients aged 18 years and older in the United States and Puerto Rico.

Is GNS561 FDA approved?

No. GNS561 is an investigational drug and has not been approved by the FDA. It is currently in Phase 1 clinical development for advanced KRAS mutated cholangiocarcinoma, and its only trial, NCT05874414, is still recruiting participants.
