Summary: Sixteen patients with metastatic malignant melanoma were treated with poly(I,C)-LC 5 mg/m2 twice weekly by intravenous injection. No antitumor responses occurred. Fever (frequently >40[degrees]C) and fatigue were dose limiting toxicities. One patient developed a fever of 42.2[degrees]C when poly(I,C)-LC was given on 2 consecutive days. Interferon was consistently detected in the serum 8 h after a single injection of poly(I,C)-LC (median titer 199 U/ml). No enhancement of interferon induction was detected on the second day when poly(I,C)-LC was given on 2 consecutive days.
