SNP Clinical Trial Gene

A Phase I Study of the PARP Inhibitor ABT-888 in Combination With Temozolomide in Acute Leukemias

This phase I clinical trial is studies the side effects and best dose of giving veliparib together with temozolomide in treating patients with acute leukemia. Veliparib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Drugs used in chemotherapy, such as temozolomide, work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. Giving veliparib together with temozolomide may kill more cancer cells.

Primary Outcomes

Measure: MTD of veliparib, determined according to incidence of dose limiting toxicity, graded using the National Cancer Institute Common Terminology Criteria for Adverse Events version 4.0

Time: 28 days

Secondary Outcomes

Description: The proportion of responders will be estimated and reported with the corresponding 90% confidence interval.

Measure: Response rate at the MTD, assessed using revised International Working Group response criteria

Time: Up to 30 days

Description: The proportion of subjects with significant inhibition will be estimated for each dose level. Summary statistics and results of the statistical tests for contingency tables will be reported.

Measure: Changes in levels of poly(ADP-ribose) (PAR)

Time: From baseline to 6 hours after drug administration on day 1 of course 1

Description: Average expression of MGMT will be measured and classified as positive versus negative (less than 20% of mean value) for all patients regardless of the administered drug dose. We will use the Fisher's exact test for 2 x 2 tables to assess whether the lack of MGMT expression correlates with the response.

Measure: Average expression of MGMT

Time: Up to 30 days

Description: The average change from baseline level in γ-H2AX and RAD51 foci will be estimated for all patients to assess whether increase in foci and response to treatment are associated. Assessed using a single group repeated measures analysis of variance (ANOVA) with 0.05 significance level.

Measure: Average change from baseline level in y-H2AX foci

Time: From baseline to 30 days

Description: The average change from baseline level in γ-H2AX and RAD51 foci will be estimated for all patients to assess whether increase in foci and response to treatment are associated. Assessed using a single group repeated measures ANOVA with 0.05 significance level.

Measure: Average change from baseline level in RAD51 foci

Time: From baseline to 30 days

Description: Repeated measures data structure will provide adequate power to estimate intra- and inter-patient variability.

Measure: Non-homologous end joining repair

Time: Up to 30 days

Description: The plausible relationship between change in DSB repair and clinical response will be examined using the Fisher's exact test.

Measure: Double strand break (DSB) repair
