Abstract
Poly(ICLC) preparation, containing poly-L-lysine and poly(I) • poly(C) at a weight ratio of 1:2, was given intravenously at a dose of 0.05 to 0.2 mg/kg to 7 patients with malignant brain tumor. Poly(ICLC) induced significant serum interferon (more than 100 reference units/ml) in all patients. The highest interferon titer induced was 875 reference units/ml. Severe side effect was not observed except fever. Hypotension, leukopenia and elevation of liver enzyme levels were observed as side effects in a few cases.
