Safety of SBRT With Anti-PD1 and Anti-IL-8 for the Treatment of Multiple Metastases in Advanced Solid Tumors and Melanoma

Nivolumab (and other agents affecting the anti-programmed death-1 \[anti-PD-1\] pathway) have demonstrated anti-tumor activity in multiple tumor types. Combinations of immune-oncology (IO) agents with complimentary mechanisms as well as radiation represent a promising strategy to improve response rates to immunotherapy and overcome resistance. In this phase I/Ib study, radiation will be used in combination with IO agents nivolumab and anti-IL-8 (BMS-986253) to assess toxicity by organ system and then assess the preliminary efficacy of the treatment regimen. In Part 1, the study will determine the safe doses of radiation by organ site in conjunction with nivolumab and BMS-986253. In Part 2, the treatment regimen will be investigated in melanoma, prioritizing acral melanoma, to describe the response rate to treatment as well as other clinical and safety outcomes. The study will also provide the opportunity to evaluate changes in the tumor microenvironment induced by the treatment.

This is a study of SBRT in combination with nivolumab and BMS-986253, a monoclonal antibody (mAb) against human interleukin-8 (IL-8), conducted in humans with advanced solid tumors. This study will evaluate the safety profile, tolerability and preliminary efficacy of SBRT in combination with BMS-986253 and nivolumab in participants with advanced solid tumors and then specifically in melanoma, focused on acral melanoma. The study will be conducted in 2 parts.

Part 1 will evaluate the safety, tolerability of different doses of SBRT in combination with nivolumab (480 mg) and BMS-986253 (2400mg) every 2 weeks (Q2W) in participants with advanced solid tumors. This phase will begin with a cohort of participants who will receive a 2,400 mg flat dose of BMS-986253 Q2W combined with 480 mg flat dose of nivolumab Q4W along with SBRT (the dose is dependent on the irradiating organ).

Part 2 will assess preliminary efficacy of SBRT in combination with nivolumab and BMS-986253 in participants with advanced/metastatic/unresectable melanoma, focusing on acral melanoma, who progressed on anti-PD-(L)1 therapy.

This study aims to determine that safe doses will be found using ablative doses of SBRT with concurrent IO agents. Additional safety, tolerability and preliminary efficacy information in specific patient population will be gathered. Twenty participants with anti-PD-(L)1 refractory advanced/unresectable/metastatic melanoma, focusing on acral melanoma, will be enrolled into efficacy phase.
