title: Phase II study of interleukin-12 for treatment of plateau phase multiple myeloma (E1A96): a trial of the Eastern Cooperative Oncology Group.
abstract: The Eastern Cooperative Oncology Group (ECOG) conducted a phase II trial of interleukin-12 (IL-12) for plateau phase multiple myeloma. Patients were initially treated with IL-12 250 ng/kg I.V. daily for 5 days every 3 weeks. The trial was modified due to toxicity after the first 16 patients. IL-12 was given 300 ng/kg subcutaneously twice weekly for 24 weeks. Of 48 eligible patients, there were 4 objective responses (8.3%), all CR. The median survival and progression-free survival were 42.8 and 11.4 months. Unacceptable grade 3 or 4 non-hematologic toxicity (31% with IL-12 subcutaneously and 63% with IL-12 intravenously) was observed.
