Study Description

Brief Summary:

This Phase 3 study assesses three two drug regimens as the initial treatment of patients who are at least 70 years of age and have newly diagnosed acute myeloid leukemia (AML) for whom the doctor does not recommend the use of standard intensive treatment or the patient has decided not to receive standard intensive treatment after being fully informed about its benefits and risks by his/her doctor. The three two drug regimens are sapacitabine administered in alternating cycles with decitabine, sapacitabine alone or decitabine or decitabine alone. The purpose of the study is to learn which drug regimen is more likely to keep AML in check as long as possible.

Detailed Description:

This is a multicenter, randomized, Phase 3 study ("SEAMLESS") comparing three two drug regimens (arms) as the front-line treatment of elderly patients aged 70 years or older with newly diagnosed acute myeloid leukemia (AML) who are not candidates for intensive induction chemotherapy. In Arm A, sapacitabine is administered in alternating cycles with decitabine, in Arm B sapacitabine is administered alone and in Arm C decitabine is administered alone. The primary efficacy endpoint is overall survival. The study is designed to demonstrate an improvement in overall survival of either of two pairwise comparisons: (1) Arm A versus Arm C or (2) Arm B versus Arm C.
