Gemcitabine and ON 01910.Na in Previously Untreated Metastatic Pancreatic Cancer

Summary

The question being asked in this study is: Will patients with advanced pancreatic cancer live significantly longer if they are treated with a combination of Gemcitabine and ON 01910.Na than if they are treated with Gemcitabine alone? There are two parts to this study. In the first part of the study, patients with metastatic pancreatic cancer who have received no prior chemotherapy for this disease will be assigned by chance either to the group that will be treated with both Gemcitabine and ON 01910.Na (about 100 patients will be in this group) or, to the group that will be treated with Gemcitabine only (about 50 patients will be in this group). How long patients survive in the 2 groups will be compared. If it looks like there is no difference between the groups, the study will stop. If it looks like patients in the group that were treated with both Gemcitabine and ON 01910.Na survive longer, the study will continue into a second part where more patients will be treated in order to confirm and better understand the findings of the first part of the study.

Detailed description

This will be a Phase III study with sample size recalculation after 100 events have occurred. The study will be open-label, randomized, controlled, multi-center and will be conducted at approximately 200 to 300 study sites (60 to 80 study sites in the first portion of the trial). In the first portion of the study, a total of 150 patients with metastatic pancreatic cancer who have received no prior chemotherapy for this disease will be randomized in a 2:1 fashion to 1 of the 2 following treatment regimens: * Arm A: Gemcitabine 1000 mg/m2 weekly for 3 weeks of a 4 week cycle + ON 01910.Na 1800 mg/m2 via 2 hr continuous intravenous infusion (CIV) infusions administered twice weekly for 3 weeks of a 4 week cycle (approximately 100 patients) * Arm B: Gemcitabine only, 1000 mg/m2 weekly for 3 weeks of a 4 week cycle (approximately 50 patients). Patients will be stratified at entry using the Eastern Cooperative Oncology Group (ECOG) performance status (ECOG scores of 0 1 vs. ECOG scores of 2; patients with higher scores will not be enrolled). Patients will remain on study until disease progression or death from any cause, whichever comes first. Moreover, after treatment discontinuation for any cause, all patients will be followed until death. After 150 patients have been enrolled, accrual will pause and patients will be followed until 100 deaths have occurred. At that time, the Data Safety Monitoring Committee (DSMC) will oversee a formal interim analysis to compare overall survival (OS) between the 2 groups and may recommend early stopping for futility. If the study continues after interim analysis, then the randomization scheme will continue up to 364 patients or the newly-calculated sample size. The maximum number of enrolled patients will be 650. The number of clinical sites may be expanded up to approximately 200 to 300 centers. Patients in the gemcitabine-only arm (Arm B) will not be allowed to cross over to the combined treatment arm (Arm A). In addition, no palliative radiotherapy will be allowed during the trial. The primary analysis will compare OS in the ON 01910.Na + gemcitabine arm (Arm A) vs. gemcitabine-only arm (Arm B) once an appropriate number of events has been reached. There are 2 secondary efficacy outcomes: progression-free survival (PFS) and objective response. Toxicity will be graded according to the National Cancer Institute Common Terminology Criteria for Adverse Events v4.03. Grade 3 and 4 hematologic toxicities and \> Grade 2 non-hematologic toxicities will be monitored.
