  Purpose
Drugs used in chemotherapy work different ways to stop tumor cells from dividing so they stop growing or die. Radiation therapy uses high-energy x-rays to damage tumor cells. Flavopiridol may make the tumor cells more sensitive to radiation therapy. Phase I trial to study the effectiveness of combining flavopiridol with radiation therapy followed by gemcitabine hydrochloride in treating patients who have locally advanced, unresectable pancreatic cancer.

Further study details as provided by National Cancer Institute (NCI):

Primary Outcome Measures:
  • Maximum tolerated dose of flavopiridol when administered biweekly in conjunction with radiation for patients with locally advanced pancreatic or extrahepatic bile duct cancer [ Time Frame: 6 weeks ]

Secondary Outcome Measures:
  • Molecular correlates of apoptosis including PARP cleavage and caspase-3 activation, as well as changes in expression of p21, phosphorylation status of pRb and cyclin D1 [ Time Frame: Baseline ]
    Will be summarized by descriptive statistics and used to generate hypothesis for further studies.

  • Molecular correlates of apoptosis including PARP cleavage and caspase-3 activation, as well as changes in expression of p21, phosphorylation status of pRb and cyclin D1 [ Time Frame: 10 weeks ]
    Will be summarized by descriptive statistics and used to generate hypothesis for further studies.


Enrollment: 46
Study Start Date: August 2002
Primary Completion Date: August 2008 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
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)

Detailed Description:

PRIMARY OBJECTIVES:

I. Determine the maximum tolerated dose of flavopiridol in combination with radiotherapy followed by gemcitabine in patients with locally advanced, unresectable pancreatic cancer.

II. Determine the toxicity of this regimen in these patients.

SECONDARY OBJECTIVES:

I. Determine the pharmacokinetics of flavopiridol in these patients. II. Determine, preliminarily, the therapeutic activity of this regimen in these patients.

OUTLINE: This is a dose-escalation study of flavopiridol.

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. The MTD is defined as the dose preceding that at which 2 of 3 or 2 of 6 patients experience dose-limiting toxicity. Once the MTD is determined, 10 additional patients are treated at the recommended phase II dose.

Patients are followed at 4 weeks and then every 8 weeks thereafter.

PROJECTED ACCRUAL: Approximately 3-46 patients will be accrued for this study within 2 years.
