A phase II trial of aclacinomycin-A in advanced squamous cell carcinoma of the head and neck.

Sixteen patients with advanced squamous cell carcinoma of the head and neck were entered into a phase II trial of Aclacinomycin-A (ACM), 100 mg/M2 administered by brief infusion every three weeks. All patients had received prior radiation therapy and prior non-anthracycline containing chemotherapy. No clinically significant disease regression was observed in fourteen patients having adequate trials. The major toxicity was myelosuppression; leukopenia occurred in 93% of patients. Gastro-intestinal toxicity was mild and included two patients with transient liver function test abnormalities. No antitumor activity was observed in this patient population which was heavily pre-treated and had a median Karnofsky performance status of only 60%. The results of other phase II trials of ACM-A have been similarly disappointing suggesting that it is not a clinically useful agent in the treatment of solid tumors.
