Safety and Efficacy Study of P276-00 in Combination With Gemcitabine in Patients With Advanced Pancreatic Cancer

This study is an open label multicenter trial to evaluate safety and efficacy of P276-00 in combination with Gemcitabine in subjects with locally advanced or metastatic pancreatic cancer. Primary objective in part A is to determine maximum tolerated dose (MTD) of P276-00 in combination with Gemcitabine and in part B to evaluate efficacy of this combination in subjects with locally advanced or metastatic pancreatic cancer. In part A, cohort of 3 subjects will be enrolled at starting dose level of P276-00 which is 100 mg/m2/ day to be given intravenously (IV) from day 1 to day 5 every 21 days. This constitutes one cycle of P276-00. If this dose is well tolerated then next cohort will be enrolled at higher dose level of P276-00. P276-00 dose escalation will continue until MTD of P276-00 in combination with Gemcitabine is determined. The subsequent dose levels of P276-00 will be 140 mg/m2/day and 185 mg/m2/day. In part B ten subjects will be evaluated at the MTD of P276-00 in combination with Gemcitabine to evaluate efficacy of the combination. Dose of Gemcitabine will be same in both parts of the study which is 1000mg/m2 over 30mins every week for 7 weeks followed by a gap of one week and then 3 weekly doses every 4 weeks. Subjects will be treated for six cycles of P276-00 in combination with Gemcitabine or until evidence of disease progression or unacceptable toxicity. Safety evaluations will be performed at regular intervals by means of record of vital parameters, physical examination and laboratory investigations for hematology and biochemistry. Efficacy assessment will be performed by means of weekly record of pain intensity, analgesic consumption, change in weight and performance status for evaluation of clinical benefit response and by means of CT scans at the end of every 2 cycles for evaluation of tumor response by RECIST (Response Evaluation Criteria in Solid Tumors)
