Perifosine in Treating Patients With Recurrent, Refractory, Locally Advanced, or Metastatic Breast Cancer
RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die.
PURPOSE: Phase II trial to study the effectiveness of perifosine in treating patients who have recurrent, refractory, locally advanced, or metastatic breast cancer.
|Study Design:||Masking: Open Label
Primary Purpose: Treatment
|Official Title:||A Phase 2 Study Of Perifosine In Metastatic Or Advanced Breast Cancer|
|Study Start Date:||June 2003|
- Determine the objective tumor response rate in patients with recurrent or refractory, locally advanced or metastatic breast cancer treated with perifosine.
- Determine the toxicity of this drug in these patients.
- Determine the stable disease rate, time to disease progression, objective response duration, and duration of stable disease in patients treated with this drug.
- Correlate potential endpoints, including phosphorylated ERK, PKB, and SAPK, phosphorylated PKC alpha, beta, and gamma isoforms, p21 ^WAF1; and activated capase-3 in tumor biopsies, with clinical outcome in patients treated with this drug.
OUTLINE: This is an open-label, multicenter study.
Patients receive a loading dose of oral perifosine on days 1 and 2 and once daily on days 3-21 during course 1. Patients receive oral perifosine once daily on days 1-21 in each subsequent course. Courses repeat every 28 days in the absence of disease progression or unacceptable toxicity. Patients achieving a complete response (CR) may receive 2 additional courses beyond the CR.
PROJECTED ACCRUAL: A total of 18-35 patients will be accrued for this study within 6-12 months.
