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

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.

The Sponsor-Investigator of this trial at University of Chicago is Steven Chmura MD, PhD The primary outcome measure, "Preliminary Estimate of the Response Rate to SBRT/Nivolumab/BMS986253 for Part II," was added to the ClinicalTrials.gov record after it was identified that this outcome had inadvertently not been entered during the initial registration process. This outcome was included in the original study protocol and has been a pre-specified primary objective for Part II since study inception. The update was made solely to align the ClinicalTrials.gov record with the approved protocol and does not represent a change to the study design, objectives, or planned analyses.
