Summary
Study start date: August 1, 1997
Actual date on which the first participant was enrolled.OBJECTIVES: I. Evaluate the safety and plasma concentration profiles of oblimersen (G3139) administered alone or in combination with docetaxel in patients with advanced solid tumors expressing the bcl-2 oncogene. II. Determine the plasma concentration profiles, maximum tolerated dose (MTD), and/or optimal biologic dose (OBD) of this treatment regimen in these patients. III. Determine the antitumor effects of G3139, at the MTD or OBD, in combination with docetaxel in patients with androgen-independent, refractory, or recurrent prostate cancer. OUTLINE: This is a dose-escalation study of oblimersen (G3139). Phase I: Patients receive G3139 IV on days 1-5 and docetaxel IV on day 5. Treatment repeats every 21 days for up to 6 courses in the absence of disease progression or unacceptable toxicity. Cohorts of 3-6 patients receive escalating doses of G3139 until the maximum tolerated dose (MTD) is determined. The MTD is defined as the dose at which no more than 2 of 3 or 2 of 6 patients experience dose-limiting toxicity. Phase II: Patients receive G3139 continuously over 21 days at one dose level below the MTD in combination with weekly docetaxel. Patients receive up to 2 more courses of therapy in the absence of disease progression or unacceptable toxicity. Patients are followed every 3 months until disease progression. PROJECTED ACCRUAL: A maximum of 57 patients (42 for phase I and 15 for phase II) will be accrued for this study.
