A Study of Oral Sapacitabine in Elderly Patients With Newly Diagnosed Acute Myeloid Leukemia

Phase 3
Completed
Conditions
Acute Myeloid Leukemia
Interventions
Registration Number
NCT01303796
Lead Sponsor
Cyclacel Pharmaceuticals, Inc.
Brief Summary

This Phase 3 study assesses 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 two drug regimens are sapacitabine administered in alternating cycles with 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 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, 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 Arm A versus Arm C.

Primary Outcome Measures
NameTimeMethod
Overall Survivalup to 43 months

The distribution of overall survival was estimated by the method of Kaplan and Meier. A log-rank analysis stratified by randomization stratification factors was used to compare overall survival between Arm A (decitabine/sapacitabine) versus Arm C (decitabine). Cox proportional hazards models were used to identify predictive factors for overall survival.

Secondary Outcome Measures
NameTimeMethod
Complete Remission With Incomplete Platelet Count Recovery (CRp)up to 43 months

Normalization of bone marrow to \<=5% blasts; peripheral neutrophils \>=1000 /microliter, platelet \<=100,000 /microliter within 2 weeks of bone marrow biopsy/aspirate; independent of transfusions\*; and no extramedullary leukemia.

\*independent of transfusions refer to no platelet transfusion for 1 week prior to achieving the response

1-year SurvivalPercentage of patients alive at 1 year after randomization (participants were assessed up to 43 months for overall survival curve estimation but this measure presents the 1 year survival rate percentage).

One-year survival is the percentage of patients who are alive at 1-year measured from the date of randomization.

Partial Remission (PR)up to 43 months

Normalization of peripheral neutrophils to \>=1000 /microliter, platelet to \>=100,000/microliter within 2 weeks of bone marrow biopsy/aspirate, \>=50% decrease in bone marrow blasts over pre-treatment but still \>5%; independent of transfusions\*

\*independent of transfusions refer to no platelet transfusion for 1 week prior to achieving the response

Stable Disease (SD)up to 43 months

Failure to achieve at least hematologic improvement (HI), but no evidence of clinically significant progression for \> 16 weeks.

Complete Remission (CR)up to 43 months

Normalization of peripheral neutrophils to \>=1000 /microliter, platelet to \>=100,000/microliter within 2 weeks of bone marrow biopsy/aspirate, and bone marrow to \<=5 % blasts; independent of transfusions\*; and no extramedullary leukemia.

\* independent of transfusions refer to no platelet transfusion for 1 week prior to achieving the response

Hematological Improvementup to 43 months

HI with duration (HI)

1. Erythroid response (HI-E) for patients with pre-treatment hemoglobin \< 11 g/dL; Major response: \>2 g/dL increase in hemoglobin; for RBC, transfusion independence\* Minor response: 1 to 2 g/dL increase in hemoglobin; for RBC, a 50% decrease in transfusion requirements

2. Platelet response (HI-P) for pre-treatment platelet count \<100,000/mm3; Major response: an absolute increase of platelet count by \>=30,000/mm3; stabilization of platelet counts and platelet transfusion independence\* Minor response: \>=50% increase in platelet count with a net increase \> 10,000/mm3 but \<30,000/mm3

3. Neutrophil response (HI-N) for absolute neutrophil count (ANC) \< 1,500/mm3 before therapy; Major response: \>=100% increase, or an absolute increase of \>500/mm3, whichever is greater Minor response: \>=100% increase, but absolute increase \< 500/mm3
