A Randomized Phase II Study of Gemcitabine, Cisplatin +/- Veliparib in Patients With Pancreas Adenocarcinoma and a Known BRCA/ PALB2 Mutation (Part I) and a Phase II Single Arm Study of Single-Agent Veliparib in Previously Treated Pancreas Adenocarcinoma (Part II)
In Brief
A Phase 2 clinical trial evaluating Biopsy Procedure, Biospecimen Collection, and 6 other interventions for Locally Advanced Pancreatic Adenocarcinoma and 3 related conditions. Active but no longer recruiting, targeting 83 participants across 12 sites in 3 countries.

Detailed Summary
This randomized phase II trial studies how well veliparib together with gemcitabine hydrochloride and cisplatin works compared to gemcitabine hydrochloride and cisplatin alone in treating patients with pancreatic cancer that has spread from where it started to nearby tissue or lymph nodes (locally advanced) or spread from the primary site (place where it started) to other places in the body (metastatic). Veliparib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Drugs used in chemotherapy, such as gemcitabine hydrochloride and cisplatin, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. It is not yet known whether giving veliparib together with gemcitabine hydrochloride and cisplatin is an effective treatment for pancreatic cancer.
Study Details
Timeline
Arms & Interventions
Patients receive veliparib PO BID on days 1-12 or 1-21 of each cycle. Patients also receive gemcitabine hydrochloride IV over 30 minutes and cisplatin IV over 30 minutes on days 3 and 10 of each cycle. Cycles repeat every 21 days in the absence of disease progression or unacceptable toxicity. Patients also undergo CT or MRI throughout study. Patients also undergo tumor tissue and blood sample collection throughout the trial and undergo tumor biopsy during screening and on study.
Patients receive gemcitabine hydrochloride IV and cisplatin IV as patients in arm A. Cycles repeat every 21 days in the absence of disease progression or unacceptable toxicity. Patients also undergo CT or MRI throughout study. Patients also undergo tumor tissue and blood sample collection throughout the trial and undergo tumor biopsy during screening and on study.
Patients receive veliparib PO BID on days 1-28 of each cycle. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity. Patients also undergo CT or MRI throughout study. Patients also undergo tumor tissue and blood sample collection throughout the trial.
There will be a small lead-in, non-randomized portion to Part I, where dose levels of veliparib 20 mg po BID (dose level 0), 40 mg po BID (dose level 1) and 80 mg po BID (dose level 2), will be evaluated on a day 1-12 schedule. The doses of gemcitabine 600 mg/m2 and cisplatin 25 mg/m2 are fixed. Three-6 patients will be evaluated per dose level starting with 20 mg po BID (dose level 0). If no dose-limiting toxicity (DLT), the dose of veliparib will be increased to 40 mg po BID (dose level 1) and subsequently to 80 mg po BID (dose level 2). If no DLT is observed at the veliparib dose of 80 mg BID day 1-12, then dose level 2A will examine veliparib at 80 mg po BID day 1-21, i.e., continuous dosing of veliparib. Subsequent cohorts will only examine continuous dosing of veliparib: dose level 3 (140mg po BID) and dose level 4 (200mg po BID). Approximately 6-24 patients total will be evaluated in this lead in portion of the study.
