In an attempt to circumvent clinical multidrug resistance, we conducted a Phase II trial of cyclosporin plus combination chemotherapy in patients with relapsed or refractory non-Hodgkin's lymphoma. Thirteen patients, all of whom had been previously treated with a doxorubicin-containing regimen, received doxorubicin 50 mg/m2 intravenous continuous infusion (IVCI) over 96 h (days 1-4), vincristine 2 mg i.v. (day 1), and etoposide 75 mg/m2 i.v. daily for 4 days (days 1-4). Four days prior to chemotherapy, patients received a loading dose of cyclosporin (0.88 mg/kg i.v. over 2 h), followed by a maintenance dose (1.8 mg/kg per day IVCI for 9 days). Cyclosporin dose escalation was permitted, conventionally defined therapeutic levels of cyclosporin were achieved; this drug was well tolerated at these doses. The study was closed due to a poor response rate; only one patient achieved a complete remission of 33 weeks' duration. Grade 3 and 4 toxicities included gastrointestinal haemorrhage (one patient), sensory neuropathy (two patients), stomatitis (two patients), and transaminase elevation (one patient). Asymptomatic grade 1-2 toxicities (elevated creatinine and transaminase levels) occurred in 33% of patients. There were no treatment associated deaths. Prolonged neutropenia and thrombocytopenia were the primary haematological toxicities. Although the addition of cyclosporin at this dose and schedule did not improve response rates in this patient group, future trials using higher doses of cyclosporin with combination chemotherapy may warrant further investigation.

Bryostatin 1 is a natural product isolated from the marine bryozoan Bugula neritina in 1982 and is currently undergoing evaluation in a number of malignancies. Twenty-five patients with relapsed, low-grade non-Hodgkin's lymphoma or chronic lyphocytic leukemia (CLL) received bryostatin 1 by 72-h continuous infusion every 2 weeks at a dose of 120 microg/m2 per course. Patients who progressed while receiving bryostatin 1 alone could participate in a feasibility study by receiving vincristine administered by bolus i.v. injection immediately after the completion of the bryostatin 1 infusion. The dose of vincristine was escalated in groups of three patients as follows: level 1, 0.5 mg/m2; level 2, 1.0 mg/m2; and level 3, 1.4 mg/m2 with vincristine doses capped at 2.0 mg for all patients. Bryostatin 1 alone resulted in one complete remission and two partial remissions. Nine patients received sequential treatment with bryostatin 1 and vincristine. The addition of vincristine at a dose of 2 mg was feasible and caused the expected dose-related sensory neuropathy. Phenotypic analysis by flow cytometric analysis on pre- and post-bryostatin 1-treated peripheral blood lymphocytes revealed up-regulation in the coexpression of CD11c/ CD22 on CD20+ B cells in two of four CLL patients studied, which is consistent with in vitro findings of differentiation of CLL cells to a hairy cell phenotype.
