Sequential administration of GM-CSF (Sargramostim) and IL-2 +/- autologous vaccine as adjuvant therapy in cutaneous melanoma: an interim report of a phase II clinical trial.
Granulocyte-macrophage colony-stimulating factor (GM-CSF) and interleukin-2 (IL-2) are 2 cytokines with distinct mechanisms of action that complement one another in the adjuvant management of melanoma. Forty-five patients with high-risk melanoma were enrolled in an open-label, single-arm, phase II clinical trial to examine the safety, tolerability, and effectiveness of this combination. After potentially curative surgery, each patient received 12 months of GM-CSF 125 microg/m2/d subcutaneously (SC) for 14 days followed by IL-2, 9 million IU/m2/d SC for 4 days (given every other cycle from months 7-12), followed by 10 days of no treatment. In addition, patients who had tumors yielding an adequate number of live cells received autologous melanoma vaccines. For months 13-24, patients received only GM-CSF 250 microg/m2 twice weekly. This is an interim analysis based on the 45 enrolled patients with a median of 15.9 months follow-up (range, 1-50 months). Thirty-two patients are alive: 9 of 13 with stage IV resected melanoma, 16 of 25 with stage III disease, and 7 of 7 with stage II disease. Twelve died of the disease, and one due to stroke. Adjuvant use of sequential GM-CSF and IL-2 +/- autologous vaccine was well tolerated with good patient compliance and seemed to benefit high-risk patients with surgically resected melanoma.
