    Notes: Summary The Southwest Oncology Group studied the response rate and toxicity of didemnin B (3.47 mg/m2 i.v. q 28 days) in patients with advanced renal cell carcinoma. There were no responses in 22 response evaluable patients. Toxicity was significant with 10 patients having grade 3 or 4 toxicity. Toxicity seen included nausea and vomiting, exacerbation of coronary artery disease, hyperglycemia, anorexia, diarrhea and hepatitis. Didemnin B was toxic but inactive in patients with renal cell treated at this dose.

    Notes: Summary AZQ, an alkylating agent with lipophilic characteristics allowing CNS penetration was studied in patients with primary CNS malignancies refractory to surgical and radiotherapeutic modalities. Responses were evaluated by three criteria: neurologic examination, performance status and CT scan of the brain. Improvement in all three parameters with stable or decreasing doses of decadron was required for a partial response. Thirty-six poor risk (prior chematherapy) patients with Grades III and IV astrocytomas were treated with 30 mg/m2. Three patients had a partial response (14, 17, 60 weeks duration). Two patients had mixed responses (worsening of one disease parameter with improvement in another), four had stable disease and one patient had improvement in neurologic parameters with a stable CT scan. Twenty-six patients had increasing disease. Fifteen good risk patients (no prior chemotherapy) with recurrent grades III and IV astrocytomas were treated at a dose of 40 mg/m2 intravenously every three weeks. There were no objective responses in this group of patients. Three patients with nonastrocytomas were treated and no responses observed. The drug was well tolerated. Myelosuppression in the form of leukopenia and thrombocytopenia was the major toxicity. Myelosuppression required dose reductions in eight patients and discontinuation of therapy due to repeated treatment delays in two patients. AZQ at doses of 30 and 40 mg/m2 given on an intermittent bolus schedule is inactive in patients with Grades III and IV recurrent astrocytoma.

    Notes: Abstract Didemnin B 6.3 mg/m2 was administered intravenously to 48 patients with recurrent or progressive central nervous system tumors. One patient of 39 (2.9%, 95% confidence limits 0.1 to 13.5) eligible patients had a confirmed partial response utilizing standard solid tumor criteria which lasted 14 months. Toxicity was significant. Nausea and vomiting and lethargy were the most frequent toxicities, but multiple severe toxicities were seen. Further investigation of Didemnin B at this dose is not warranted in patients with central nervous system malignancies.
