Abstract | PURPOSE: PATIENTS AND METHODS:
Hu14.18-IL2 was given at the recommended phase II dose of 12 mg/m2/day on days 4-6 of a 28-day cycle with GM-CSF (250 mg/m2/dose, days 1-2 and 8-14) and isotretinoin (160 mg/m2/day, days 11-25). Tolerability was determined on the basis of the number of unacceptable toxicities observed. Response was evaluated separately for patients with disease measurable by standard radiologic criteria (stratum 1), and for patients with disease evaluable only by I123-metaiodobenzylguanidine (I123-MIBG) scan and/or bone marrow histology (stratum 2). RESULTS: Fifty-two patients with recurrent or refractory neuroblastoma were enrolled; 51 were evaluable for toxicity and 45 were evaluable for response. Four patients had unacceptable toxicities, well below the protocol-defined rule for tolerability. Other grade 3 and 4 nonhematologic toxicities were expected and reversible. No responses were seen in stratum 1 (n = 14). In stratum 2 (n = 31), 5 objective responses were confirmed by central review (3 complete, 2 partial). CONCLUSIONS:
Hu14.18-IL2 given in combination with GM-CSF and isotretinoin is safe and tolerable. Patients with MIBG and/or bone marrow-only disease had a 16.1% response rate, confirming activity of the combination.
