Phase I trial to study the effectiveness of irinotecan plus cyclosporine and phenobarbital in treating patients who have solid tumors or lymphoma that is refractory to standard therapy. Drugs used in chemotherapy use different ways to stop cancer cells from dividing so they stop growing or die. Cyclosporine and phenobarbital may enhance the effectiveness of irinotecan.

Study summary:

OBJECTIVES: I. Determine the maximum tolerated dose of irinotecan (CPT-11) when infused weekly with cyclosporine (CYSP) in patients with solid tumors or lymphoma refractory to standard therapy. II. Determine whether CYSP modulates the pharmacokinetics and pharmacodynamics of CPT-11 and its active metabolite, SN-38. III. Determine whether phenobarbital modulates the pharmacokinetics and pharmacodynamics of CPT-11 and SN-38. OUTLINE: This is a dose escalation study of irinotecan. Patients are stratified according to gender. Part I: Patients receive cyclosporine IV over 6 hours and irinotecan IV over 90 minutes weekly for 4 weeks. Courses repeat every 6 weeks in the absence of unacceptable toxicity or disease progression. Cohorts of 3-12 patients receive escalating doses of irinotecan until the maximum tolerated dose (MTD) is determined. The MTD is defined as the dose at which at least one third of patients experience dose limiting toxicity (DLT). Part IIA: If the DLT is diarrhea in part I, then part IIA is opened. Patients receive oral phenobarbital, cyclosporine as in part I, and irinotecan at the MTD from part I. Dose escalation occurs as in part I to determine a new MTD. If the DLT continues to be diarrhea, the study is closed. Part IIB: If the DLT is neutropenia in part I, then part IIB is opened. Patients receive cyclosporine as in part I and escalating doses of irinotecan to determine a new MTD. Part III: If the DLT is neutropenia in part IIA or any DLT in part IIB, patients receive phenobarbital, cyclosporine, and irinotecan at the MTD determined as in part IIA or part IIB. Dose escalation continues until a new MTD is determined.
