Currently, elderly patients with AML and high risk MDS, who are ineligible to receive induction chemotherapy and fail HMA +/- combination, have very poor outcomes and there is no FDA-approved therapy outside of some targeted therapies which can only be applied to a small patient population. CPX-351 is an investigational (experimental) drug that works by combining two anti-cancer drugs cytarabine and daunorubicin. CPX-351 is experimental because it is only FDA approved for the treatment of adults with two types of AML: newly diagnosed therapy-related AML or AML with myelodysplasia-related changes.~This is an open label clinical trial of lower doses of CPX-351 in relapsed/primary refractory older AML and MDS patients ineligible to receive intensive chemotherapy. The first arm is for particpants with primary refractory/relapsed AML and the second arm is for higher risk MDS participants after HMA failure.
The purpose of this study is to evaluate how effective lower doses of CPX-351 are in older participants with relapsed/refractory acute myeloid leukemia (AML) who are not eligible to receive intensive chemotherapy and in participants with myelodysplastic syndromes (MDS) after Hypomethylating Agents (HMA) failure.
