Trastuzumab Plus R115777 in Treating Patients With Advanced or Metastatic Cancer

National Cancer Institute (NCI)24 enrolled

Overview

Phase I trial to study the effectiveness of trastuzumab plus R115777 in treating patients who have advanced or metastatic cancer. Monoclonal antibodies such as trastuzumab can locate tumor cells and either kill them or deliver tumor-killing substances to them without harming normal cells. Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Combining trastuzumab with R115777 may kill more tumor cells.

OBJECTIVES: I. Determine the maximum tolerated dose of R115777 when administered with trastuzumab (Herceptin) in patients with advanced or metastatic adenocarcinoma. II. Assess the toxicities and pharmacokinetics of this treatment regimen in this patient population. III. Determine the antitumor activity of this treatment regimen in these patients. IV. Determine the relative biologic endpoints of this regimen and correlate them with toxicity and pharmacokinetic parameters in these patients. OUTLINE: This is a dose escalation, multicenter study of R115777. Patients receive trastuzumab (Herceptin) IV over 90 minutes on days 1, 8, 15, and 22 plus oral R115777 twice daily for 3 weeks. Treatment continues every 28 days in the absence of disease progression or unacceptable toxicity. Cohorts of 3-6 patients receive escalating doses of R115777 until the maximum tolerated dose (MTD) is determined. The MTD is defined as the dose at which no more than 1 of 6 patients experiences dose limiting toxicities. Patients are followed every 30 days until toxicity resolves.
