|Official Title:||A Phase II Study of Tosedostat in Combination With Either Cytarabine or Decitabine in Newly Diagnosed AML or High-Risk MDS|
- Proportion of patients alive (survival rate) [ Time Frame: 4 months after beginning treatment ] [ Designated as safety issue: No ]Success measured by improvement of survival rate to 80% from the historical 60% while not decreasing the CR rate to < 30% from the historical 50%.
- Proportion of patients achieving CR [ Time Frame: 4 months after beginning treatment ] [ Designated as safety issue: No ]Defined by Cheson et al.
|Study Start Date:||May 2012|
|Primary Completion Date:||June 2013 (Final data collection date for primary outcome measure)|
Experimental: Arm I (tosedostat and cytarabine)
Patients receive tosedostat PO QD on days 1-35 and cytarabine IV on days 1-5.
Other Names:Drug: cytarabine
Experimental: Arm II (tosedostat and decitabine)
Patients receive tosedostat PO QD on days 1-35 and decitabine IV on days 1-5.
Other Names:Drug: decitabine
I. To determine the 4 month survival and complete remission (CR) rates of tosedostat in combination with either cytarabine or decitabine in untreated acute myeloid leukemia (AML) or high-risk myelodysplastic syndrome (MDS).
I. To assess safety and tolerability of tosedostat in combination with either cytarabine or decitabine.
II. To determine the treatment related mortality defined as death within the first 30 days of beginning treatment.
III. To estimate rates of disease-free survival (DFS) and the 1 year overall survival (OS).
OUTLINE: Patients are randomized to 1 of 2 treatment arms.
ARM I: Patients receive tosedostat orally (PO) once daily (QD) on days 1-35 and cytarabine intravenously (IV) on days 1-5.
ARM II: Patients receive tosedostat PO QD on days 1-35 and decitabine IV on days 1-5.
If the patient develops a significant increase in their circulating or bone marrow blast count, the subsequent cycle may be started as early as day 21 of the current cycle. In both arms, treatment repeats every 35 days for up to 3 courses in the absence of disease progression or unacceptable toxicity. Patients achieving CR or partial CR (pCR) may receive 2 additional courses of treatment.
After completion of study treatment, patients are followed up every 3 months for 2 years and then annually for 3 years.
