| Abstract |
Carminomycin (CMN) was administered i.v. to 44 patients with a variety of nonhematological cancers every 4 weeks at doses of 15, 20, 22.5, and 25 mg/sq m. Granulocytopenia was the dose-limiting toxicity. The median granulocyte count for previously untreated patients receiving 22.5 mg/sq m was 0.962 cells/microliters, and for previously treated patients receiving 20 mg/sq m it was 0.420 cell/microliters. Moderate to severe phlebitis was associated with drug administration in 50% of cases. Nausea, vomiting, and alopecia were mild. Three of nine patients who received a total CMN dose of greater than or equal to 100 mg/sq m (mean, 132 mg/sq m) developed unexplained decreases in radionuclide cardiac ejection fraction, with one patient developing decreased QRS amplitude and congestive heart failure at a total dose of 160 mg/sq m. CMN is rapidly metabolized to carminomycinol. The elimination half-lives of CMN and carminomycinol are 6 to 10 and 50 hr, respectively. CMN was found to be a more potent inhibitor of human granulocyte-macrophage colony-forming units than was carminomycinol. Objective partial responses were seen in two of seven previously untreated patients with non-small cell lung cancer and one of three patients with squamous cell carcinoma of the head and neck previously untreated with chemotherapy.
