Frequently asked questions about GX15-070MS

What is GX15-070MS used for?

GX15-070MS is an investigational small molecule being studied for the treatment of chronic lymphocytic leukemia (CLL), a type of blood cancer. It has been evaluated specifically in previously untreated CLL patients. The drug is in Phase 1 clinical development and is not approved for any indication.

Who is developing GX15-070MS?

GX15-070MS is being developed by Teva Pharmaceutical Industries Limited, which trades on the New York Stock Exchange under the ticker TEVA. The company sponsored the clinical trial evaluating the drug in chronic lymphocytic leukemia.

What phase is GX15-070MS in?

GX15-070MS is in Phase 1 clinical development. It has completed one Phase 1/2 trial in chronic lymphocytic leukemia, and there are currently no active trials listed for this drug. It is investigational and has not received FDA approval.

What clinical trials is GX15-070MS in?

GX15-070MS has been studied in one completed clinical trial: NCT00600964, titled "A Phase I/II Study of GX15-070MS in Untreated CLL." The trial enrolled 26 participants across the United States and Canada and evaluated the drug in adults with chronic lymphocytic leukemia.

Is GX15-070MS FDA approved?

No, GX15-070MS is not FDA approved. It remains an investigational drug in Phase 1 clinical development for chronic lymphocytic leukemia. The only completed trial was an early-stage study, and no regulatory approval has been granted for this asset.
