Trial Outcomes & Findings for Treatment of Resistant Metastatic Melanoma Using Decitabine, Temozolomide and Panobinostat (NCT NCT00925132)

NCT ID: NCT00925132

Last Updated: 2017-07-02

Results Overview

A DLT was any Grade 4 toxicity for neutrophils or platelets for ≥ 7 days, Grade 3 toxicity for neutrophils for ≥ 21 days, any Grade 3 solid organ toxicity not explainable by another cause (e.g. neurotoxicity, GI toxicity), metabolic/laboratory toxicity (≥10 x ULN AST) for ≥ 14 days, any Grade 4 infection or QTcF\> 500msec EKG. DLTs were assessed according to the Common Toxicity Criteria for Adverse Events (CTCAE) version 3.0. All adverse events were collected and graded to determine DLTs as assessed according to the Common Toxicity Criteria for Adverse Events (CTCAE) version 3.0. DLTs were assessed to determine the recommended Decitabine and Panobinostat dose for the Phase II portion of the trial.

Participant Flow

Subjects were recruited between December 2009 through June 2015. The study population was accessed via the Principal Investigator's medical clinic at Holden Comprehensive Cancer Center.

Following consent, all subjects undergo screening procedures to verify eligibility for participation in the study. Screening included physical exam, blood and urine tests to check general health, blood test for fetal hemoglobin, blood test for pregnancy (only for women of childbearing age), ECG and Echo, CT and FDG-PET, and tumor measurements

PRIMARY outcome

Timeframe: 6 weeks (one full cycle)

Population: Number of patients within the 4 dosing cohorts evaluable for DLTs following administration of one full cycle

A DLT was any Grade 4 toxicity for neutrophils or platelets for ≥ 7 days, Grade 3 toxicity for neutrophils for ≥ 21 days, any Grade 3 solid organ toxicity not explainable by another cause (e.g. neurotoxicity, GI toxicity), metabolic/laboratory toxicity (≥10 x ULN AST) for ≥ 14 days, any Grade 4 infection or QTcF\> 500msec EKG. DLTs were assessed according to the Common Toxicity Criteria for Adverse Events (CTCAE) version 3.0. All adverse events were collected and graded to determine DLTs as assessed according to the Common Toxicity Criteria for Adverse Events (CTCAE) version 3.0. DLTs were assessed to determine the recommended Decitabine and Panobinostat dose for the Phase II portion of the trial.

PRIMARY outcome

Timeframe: 12 weeks (2 cycles)

Population: Number of patients evaluable for tumor response assessment following 2 cycles of treatment

Tumor response rate was assessed using RECIST criteria in which a complete response was the disappearance of all target lesions; Partial response was a 30% decrease in the sum of the longest dimension (LD) of target lesions, relative to baseline measurement; Progressive disease was an increase of 20% or more in the sum of the LD of target lesions; and Stable disease was a decrease in tumor size of less than 30% or increase of less than 20%. Tumor response rate was also assessed using CHOI's criteria in which a response was a 10% decrease in tumor size or a 15% decrease in tumor density on contrast-enhanced computed tomography scan. Tumor response rates were assessed in order to determine effectiveness of the treatment regimen which was defined by the response rate of at least 30% as measured by either the RECIST or Choi's criteria, and ineffective if the rate is less than 15% on both.
