Pemetrexed, Gemcitabine, and Radiation Therapy in Treating Patients With Locally Advanced Pancreatic Cancer

Phase 1
Terminated
Conditions
Pancreatic Cancer
Interventions
Device: Radiotherapy
Registration Number
NCT00310050
Lead Sponsor
Wake Forest University Health Sciences
Brief Summary

RATIONALE: Pemetrexed may stop the growth of tumor cells by blocking some of the enzymes needed for their growth. Drugs used in chemotherapy, such as gemcitabine, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Radiation therapy uses high energy x-rays to kill tumor cells.

PURPOSE: This phase I trial is studying the side effects and best dose of pemetrexed when given together with radiation therapy in treating patients with locally advanced pancreatic cancer.

Detailed Description

OBJECTIVES:

Primary

* Determine the maximum tolerated dose of pemetrexed disodium when given in combination with upper abdominal radiotherapy after induction therapy comprising gemcitabine hydrochloride and pemetrexed disodium followed by consolidation therapy with gemcitabine hydrochloride in patients with locally advanced pancreatic cancer.

* Determine the quantitative toxicity of this regimen in these patients.

Secondary

* Determine the quantitative and qualitative dose-limiting toxicities of pemetrexed disodium in combination with upper abdominal radiation therapy.

* Evaluate patterns of failure, response, and survival of these patients at 1 year

OUTLINE: This is an open-label, nonrandomized, dose-escalation study of pemetrexed disodium.

* Induction therapy: Patients receive pemetrexed disodium IV over 10 minutes and gemcitabine hydrochloride IV over 30 minutes on day 1. Treatment repeats every 14 days for 3 courses. Approximately 2 weeks later, patients without disease progression proceed to chemoradiotherapy.

* Chemoradiotherapy: Patients receive pemetrexed disodium IV over 10 minutes on days 1, 15, and 29 and undergo radiotherapy once daily 5 days a week for 5 ½ weeks. Approximately 2-3 weeks later, patients without disease progression proceed to consolidation therapy.

Cohorts of 3-9 patients receive escalating doses of pemetrexed disodium during chemoradiotherapy until the maximum tolerated dose (MTD) is determined. The MTD is defined as the dose at which ≤ 20% or ≤ 2 of 9 patients experience dose-limiting toxicity.

* Consolidation therapy: Patients receive gemcitabine hydrochloride IV over 30 minutes on days 1 and 8. Treatment repeats every 21 days for 2 courses in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed periodically.

PROJECTED ACCRUAL: A total of 25 patients will be accrued for this study.
