[Phase II study of recombinant human interferon gamma (S-6810) in renal cell carcinoma. Urological Cooperative Study Group of Recombinant Human Interferon Gamma (S-6810)].
A phase II study of recombinant human interferon gamma (rHuIFN-gamma) administered intravenously and intramuscularly was carried out in 84 patients with advanced renal cell carcinoma with the cooperation of 18 institutions throughout Japan. The eligibility of the patients and evaluation of the responses were undertaken according to the general criteria proposed by Drs. Koyama and Saito. Out of 84 cases entered in this phase II study, 62 patients were evaluable for antitumor effects. In the case of continuous administration of 8-12 X 10(6) U/m2/day interferon for 4 weeks, 32 patients were evaluable. The response rate was 6.3%. In the case of intermittent therapy of 40 X 10(6) U/m2/day interferon for 8 weeks, six out of 30 patients (20%) were evaluable as responders. Among them, one patient showed a complete response, all patients tolerated this type of interferon well. Major adverse effects were fever (86.8%), anorexia (67.1%), fatigue (53.9%) and leukopenia (42.1%). No life-threatening toxicities were found. The results of this study showed that rHuIFN-gamma had antitumor activity against renal cell carcinoma.
