Thirty-five eligible patients with disseminated malignant melanoma received intramuscular recombinant leukocyte interferon (IFN-rA), 50 X 10(6) U/m2 three times weekly (TIW) for an intended duration of 12 weeks concomitant with daily oral cimetidine, 1,200 mg/d in four divided doses. For all study participants, the median survival time was six months. Among 21 "good risk" patients (performance score [PS] 0, 1 and no prior chemotherapy), we observed seven partial regressions (33%). Six patients had stability of disease (29%), seven had immediate disease progression, and one discontinued treatment after two doses without tumor evaluation due to side effects. Times to disease progression of five patients with regressions of soft-tissue disease were 2.1, 3.3, 3.5, 3.7, and 4.3 months. Two patients had partial regressions of lung nodules for 2.0 and 3.8 months. We observed one regression among 14 "poor risk" patients (PS 2, 3, or prior chemotherapy). A 46-year-old woman with prior treatment had a partial regression of soft-tissue disease for 4.1 months. Four "poor risk" patients achieved disease stability, and nine progressed immediately. Leukopenia (WBC count less than 4,100/microL) affected 21 (66%) of 32 patients with WBC count data. The median count was 3,100/microL; range, 1,300 to 8,400/microL. We detected two cases of mild thrombocytopenia (100,000 and 120,000/microL). Other noteworthy toxicities included moderate-to-severe nausea (34%), anorexia (63%), and fatigue (80%). A...
