Study Design | Allocation: Randomized; Intervention Model: Crossover Assignment; Masking: None (Open Label); Primary Purpose: Treatment |

Other: Radiation therapy and high-dose IL-2 Drug: High-dose IL-2 |
Enrollment | 44 |
Recruitment Details | A total of 63 potential patients were screened for eligibility at Providence Cancer Institute Franz Clinic and Compass Oncology East Clinic from 2011 to 2017. |
Pre-assignment Details | Of the 50 patients who signed consent, six were excluded (3 due to rapid melanoma progression during screening, 2 due to cardiac ischemia on exercise tolerance testing, and 1 due to insurance issues). Of the 44 enrolled patients, 20 were assigned to Arm A, and 7 of those patients chose to participate in the optional crossover portion of the study. |
Arm/Group Title | Arm A: IL-2 Monotherapy | Arm B: SBRT + IL-2 |

Patients receive standard high-dose IL-2 therapy, with an opportunity to crossover to the experimental arm if there is disease progression noted after two cycles of high-dose IL-2. Crossover patients will be included in Arm A. High-dose IL-2: IL-2 will be given on a Monday at a dose of 600,000 IU per kilogram IV every 8 hours for up to 14 doses each cycle. The second cycle is planned 16 days after cycle 1 but may be delayed up to one week to allow toxicity to resolve. The maximum number of doses that can be given during two cycles will be 28 doses. Patients who respond after two cycles can receive 4 more cycles of IL-2. Patients with disease progression after 2 cycles may elect to receive radiation before a 3rd cycle of IL-2. If patients crossover, IL-2 will be given on the Monday following the last dose of radiation, at a dose of 600,000 IU per kilogram IV every 8 hours for a maximum of 14 doses each cycle. Another cycle is planned 16 days after cycle 3 but may be delayed up to one week to allow toxicity to resolve. |
Patients 1-20 who are assigned to receive radiation therapy will receive a single dose of radiation before IL-2; patients 21-44 assigned to receive radiation will receive two doses of radiation before receiving high-dose IL-2. Radiation therapy and high-dose IL-2: Patients 1 - 20 will receive a single fraction of radiation. Patients 21 through the completion of the study will receive two fractions. The dose for all patients will be 20 Gy per fraction to the prescription line at the edge of the planning treatment volume (PTV) with the last dose delivered on a Friday before IL-2 administration. For patients receiving two radiation doses, the doses can be administered on the Wednesday and Friday before IL-2 starts. Patients who are assigned to IL-2 monotherapy and have progressive disease after two IL-2 cycles are then eligible to receive SBRT before cycle 3 of IL-2 commences, single fraction for patients 1-20 and two fractions for patients 21- end of study. |
