Trial Outcomes & Findings for Vorinostat in Treating Patients With Acute Myeloid Leukemia (NCT NCT00305773)
NCT ID: NCT00305773
Last Updated: 2014-05-19
Results Overview
The confirmed complete response rate was estimated by the number of participants with CR divided by the total number of evaluable participants. According to the International Working Group (IWG) Criteria for response in AML, to be considered a CR, the following must be met for at least 4 weeks: ANC \> 1500/mL, platelets \> 100000/mL, no circulating blasts, bone marrow cellularity \>20% (biopsy), trilineage maturation, \< 5% bone marrow blasts, no auer rods and no extramedullary disease.

Participant Flow
A total of 37 participants were enrolled into this trial between January 2006 and August 2007. One patient on Arm A was ineligible; this participant was included in all analyses.

SECONDARY outcome
Timeframe: Duration of study (up to 2 years)Population: This data was not (and will never be) analyzed. In place of this outcome, time to treatment failure, analyzed and reported as a secondary outcome.
Time to Progression (TTP) for each patient will be calculated as the number of days from date of registration to either date when disease progression was documented or date of last evaluation without disease progression. The TTP distribution will be estimated using the method of Kaplan-Meier

SECONDARY outcome
Timeframe: Duration of study (up to 2 years)Overall survival (OS) was defined as the time from registration to death of any cause. Surviving patients were censored at the date of last follow-up. The median OS with 95% CI was estimated using the Kaplan Meier method.
