Bryostatin 1 Plus Gemcitabine in Treating Patients With Advanced Cancer

April 22, 2014 updated by: Barbara Ann Karmanos Cancer Institute

Phase I Study of Bryostatin 1 and Gemcitabine (Gemzar)

RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Combining more than one drug may kill more tumor cells.

PURPOSE: Phase I trial to study the effectiveness of bryostatin 1 plus gemcitabine in treating patients who have advanced cancer that has not responded to previous treatment.

Detailed Description

OBJECTIVES:

  • Determine the maximum tolerated dose of gemcitabine when given concurrently with bryostatin 1 to patients with advanced refractory cancer.
  • Access the pattern of toxicity of this drug regimen in this patient population.
  • Determine the objective response rate, duration of response, and overall survival in patients treated with this drug regimen.
  • Determine the influence of bryostatin 1 on the pharmacokinetics of gemcitabine.

OUTLINE: This is a dose escalation study.

Patients receive gemcitabine IV over 30 minutes, immediately followed by bryostatin 1 IV over 24 hours, weekly for 3 weeks (days 1, 8, and 15). Treatment repeats every 28 days in the absence of unacceptable toxicity or disease progression.

Cohorts of 3-6 patients receive escalating doses of gemcitabine and bryostatin 1 until the maximum tolerated dose (MTD) is determined. The MTD is defined as the dose preceding that at which 2 of 6 patients experience dose limiting toxic effects.

PROJECTED ACCRUAL: Approximately 2-3 patients per month will be accrued for this study.
