title: Phase II clinical study on the effects of recombinant human interleukin-3 on thrombocytopenia after chemotherapy for advanced ovarian cancer. SDZ ILE 964 [IL-3] Study Group.
abstract: The efficacy, safety, and optimum clinical dose of recombinant human interleukin-3 (rhIL-3) was examined in ovarian cancer patients with thrombocytopenia after cancer chemotherapy. In cases with a platelet count < 75,000/mm3 during the control observation period, rhIL-3 was administered subcutaneously at a dose of 5 or 10 micrograms/kg, once a day for 10 days starting from day 4 of the subsequent chemotherapy course. Comparison between the control observation period and the rhIL-3 administration period showed a significant improvement or a tendency toward improvement in increasing the nadir platelet count and the recovery of the platelet count. The major adverse reactions were pyrexia, fatigue, and headache, which were well controlled by the use of antipyretics, analgesics, and antiinflammatory agents. Adverse reactions were for the most part transient and disappeared quickly during or after rhIL-3 administration. Although severe adverse reactions were not observed, the incidence of grade 2 and 3 adverse reactions according to a World Health Organization (WHO) Toxicity Scale were slightly higher in the 10 micrograms/kg/d group. As a consequence, the 5 micrograms/kg/d dose was considered to have a slightly better safety profile than the 10 micrograms/kg/d dose. Although there was no significant difference in the efficacy (the platelet count) between the two doses, the safety profile of the 5 micrograms/kg/d dose was slightly better than the 10 micrograms/kg/d group. Therefore, the 5 micrograms/kg/d was considered to be the optimum clinical dose.
