Resumen
Fecha de inicio: 1 de febrero de 1997
Fecha en la que se inscribió al primer participante.The Phase I clinical trial of the combination of 120-hour continuous intravenous infusion of vinblastine with oral PSC 833 has shown activity in patients with advanced malignancies, particularly renal cell cancer. The MTD of vinblastine in combination with the oral drink solution of PSC 833 was determined to be 0.9 mg/m2/day for five days and 12.5 mg/kg po q 12 hours for eight days, respectively. For the soft gel capsule formulation, the MTD was determined to be 0.6 mg/m2/day vinblastine for five days and 4 mg/kg po q 6 hours PSC 833 for eight days. Ataxia was the dose limiting toxicity. Of the 46 patients, two complete remissions and one partial remission were seen among 29 patients with renal cell carcinoma. In this Phase I study, patients with advanced renal carcinoma will be treated with escalating doses of vinblastine given as a 72 hour infusion, starting at approximately 40% of the total standard dose. A shorter infusion schedule of vinblastine was chosen since there is evidence in other cytotoxic combinations that PSC 833 increases the AUC and decreases the plasma clearance of chemotherapeutic agents by approximately twofold. Cytochrome P 450 3A or CYP3A, which is the major cytochrome enzyme in the metabolism of vinblastine and PSC 833, will be measured during the first and fourth cycle through an in vivo test using a single intravenous dose of midazolam, a short-acting benzodiazepine. Vinblastine and PSC 833 pharmacokinetics will be performed at the same time. For patients with accessible lesions, tumor biopsy will be requested.
