Frequently asked questions about CLN-049

What is CLN-049 used for?

CLN-049 is an investigational small molecule being studied for the treatment of relapsed/refractory acute myeloid leukemia (AML) and myelodysplastic syndrome (MDS). It is also being evaluated in combination with azacitidine and venetoclax for AML patients. The drug is currently in Phase 1 clinical development.

Who makes CLN-049?

CLN-049 is being developed by Cullinan Therapeutics, Inc., a biopharmaceutical company traded on the stock exchange under the ticker symbol CGEM. The company is conducting clinical trials of CLN-049 in the United States for the treatment of acute myeloid leukemia and related conditions.

What phase is CLN-049 in?

CLN-049 is in Phase 1 clinical development. It is an investigational drug, meaning it has not been approved by regulatory authorities and is still being studied in clinical trials. The drug has received Fast Track and Orphan Drug designations from the FDA for its intended indications.

What clinical trials is CLN-049 in?

CLN-049 is being studied in two Phase 1 clinical trials. The first trial, NCT05143996, is recruiting patients with relapsed/refractory acute myeloid leukemia or myelodysplastic syndrome. The second trial, NCT07722767, is a Phase 1b study of CLN-049 in combination with azacitidine and venetoclax in AML patients, which has not yet started recruiting.

Is CLN-049 FDA approved?

No, CLN-049 is not FDA approved. It is an investigational drug currently in Phase 1 clinical trials. The FDA has granted CLN-049 Fast Track and Orphan Drug designations, which are intended to expedite the development and review of drugs for serious conditions, but the drug remains in clinical development.
