title: N-(phosphonacetyl)-L-aspartate (PALA) in advanced malignant melanoma: a phase II trial of the EORTC Malignant Melanoma Cooperative Group.
abstract: Thirty-nine patients with measurable advanced malignant melanoma were entered in a phase II trial with PALA. Among the 36 evaluable patients there were 18 men and 18 women, with a median age of 53 yr (29-73) and a median performance status (Karnofsky) of 100 (50-100). Indicator lesion consisted essentially of soft tissue lesions (29 patients) and/or lung metastases (9 patients). Only three patients had received prior chemotherapy. PALA was given as a 60-min i.v. infusion at a daily dose of 2.5 g/m2 for two consecutive days. Courses were repeated every two weeks. A median number of 3 courses (2-8) were administered. Partial response (greater than 50%) was obtained in 4 patients for 6-17 weeks. Eight patients had stable disease after 3 courses of PALA and 24 had progressive disease. Toxic effects were generally mild to moderate and mainly included cutaneous toxicity, nausea and vomiting, stomatitis, and diarrhea. Myelosuppression was rare and negligible. It is concluded that PALA given at the dose schedule selected for this trial is fairly well tolerated and has borderline antitumor activity in good-risk patients with advanced malignant melanoma.
