Adenocarcinoma of the Pancreas, Recurrent Pancreatic Cancer, Stage II Pancreatic Cancer
About this trial
This is an interventional treatment trial for Adenocarcinoma of the Pancreas

Arms of the Study
Arm 1
Experimental
Treatment (alvocidib, gemcitabine hydrochloride, 3DRT)
Patients receive flavopiridol IV over 1 hour twice weekly (on days 1 and 4 or days 2 and 5) for 6 weeks. Concurrently, patients undergo radiotherapy once daily 5 days a week for 5.5 weeks. Treatment continues in the absence of disease progression or unacceptable toxicity. Four weeks after the completion of radiotherapy, patients are re-evaluated*. Beginning within 4-7 weeks after the completion of chemotherapy and radiotherapy, patients receive gemcitabine hydrochloride alone or in combination with another cytotoxic agent or gemcitabine hydrochloride combined with a targeted drug (e.g., erlotinib or bevacizumab) at the discretion of the oncologist. NOTE: *Patients whose imaging studies suggest potential curative resection are referred for a surgical evaluation before initiating gemcitabine hydrochloride therapy. Cohorts of 3-6 patients receive escalating doses of flavopiridol until the maximum tolerated dose (MTD) is determined. Continued (see detailed description)
