Gemcitabine and Tanespimycin in Treating Patients With Stage IV Pancreatic Cancer - Full Text View

Information provided by:	National Cancer Institute (NCI)
ClinicalTrials.gov Identifier:	NCT00577889

Purpose

RATIONALE: Drugs used in chemotherapy, such as gemcitabine and tanespimycin, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Giving more than one drug (combination chemotherapy) may kill more tumor cells.

PURPOSE: This randomized phase II trial is studying three different schedules of gemcitabine and tanespimycin to see how well they work in treating patients with stage IV pancreatic cancer.

Arms	Assigned Interventions
Experimental: Arm I Patients receive gemcitabine hydrochloride IV over 30 minutes on days 1 and 8 and tanespimycin (17-AAG) IV over 1 hour on day 9 of course one.

Detailed Description:

OBJECTIVES:

Primary

To assess the effect of gemcitabine hydrochloride and tanespimycin (17-AAG) on 6-month survival rate in patients with stage IV pancreatic adenocarcinoma.

Secondary

To determine the overall survival of these patients.
To determine the time to disease progression (TTP) in these patients.
To determine the confirmed response rate and duration of response in these patients.
To determine the time to treatment failure in these patients.
To determine the adverse events in these patients.

Tertiary

To determine the effects of treatment on molecular targets, such as CDK4, akt, phospho-akt, Hsp90, Hsp70, and CHK1, and correlate these with clinical endpoints, including survival at 6 months, TTP, response rate, and overall survival.
To determine the effect of gemcitabine hydrochloride metabolizing enzyme genotype on toxicity, and clinical outcome.

OUTLINE: This is a multicenter study. Patients are stratified according to ECOG performance status (0, 1, or 2). Patients are randomized to 1 of 3 treatment arms.

Arm I: Patients receive gemcitabine hydrochloride IV over 30 minutes on days 1 and 8 and tanespimycin (17-AAG) IV over 1 hour on day 9 of course one.
Arm II: Patients receive gemcitabine hydrochloride IV over 30 minutes on days 1 and 8 and 17-AAG IV over 1 hour on days 2 and 9 of course one.
Arm III: Patients receive gemcitabine hydrochloride IV over 30 minutes on day 8 and 17-AAG IV over 1 hour on days 1 and 9 of course one.

Beginning with course two (and for all subsequent courses), all patients receive gemcitabine hydrochloride IV over 30 minutes on days 1 and 8 and 17-AAG IV over 1 hour on days 2 and 9. Treatment repeats every 3 weeks in the absence of disease progression or unacceptable toxicity

Blood samples are collected at baseline and periodically during treatment for pharmacogenetic studies. Tumor tissue samples that are available are also collected for laboratory studies. Samples are analyzed for number of circulating tumor cells, levels of intracellular targets (e.g., CDK4, akt, phospho-akt, Hsp90, Hsp70, and CHK1), single nucleotide DNA polymorphisms, and Vav1 expression. Samples are analyzed by reverse transcriptase-polymerase chain reaction, immunofluorescence, and immunohistochemistry.

After completion of study treatment, patients are followed periodically for up to 2 years.
