A phase II study of menogaril (NSC-269148) in colorectal carcinoma

Summary In this phase II trial, menogaril was administered to patients with metastatic colon cancer at a dose of 200 mg/m² IV over one hour with cycles repeated every 28 days provided the absolute granulocyte count was 2000 cells/l. Dose adjustments up or down were made depending upon nadir counts. Twenty-four patients were entered on this study with 21 eligible and evaluable for response. There was 1 CR lasting four and one-half months and 1 PR lasting three months for an overall CR s+ PR rate of 10% with a 95% confidence interval of 1% to 30%. Six patients (29%) had stable disease and 13 (62%) progressed. Median survival is 13.1 months. Toxicity was primarily hematologic with two cases of life-threatening leukopenia (< 1000 cells/l) and one case of life-threatening granulocytopenia (< 250 cells/l) among the 21 eligible patients, and one case of life-threatening leukopenia and granulocytopenia in one ineligible patient. There were no deaths due to treatment.
