NCT07453342
This observational study aims to comprehensively characterize immune-related adverse events (irAEs) occurring during immune checkpoint inhibitor (ICI) therapy in cancer patients and to evaluate the safety and clinical outcomes of ICI rechallenge following irAE resolution. In addition to detailed clinical data collection, the study incorporates biospecimen acquisition, when clinically indicated and feasible, including peripheral blood and organ-specific specimens (e.g., bronchoalveolar lavage fluid for ICI-related pneumonitis, liver biopsy tissue for ICI-related hepatitis, and other relevant clinical specimens). These samples will support exploratory immunologic and molecular analyses to better understand mechanisms underlying irAE development, resolution, and recurrence after rechallenge. This study is designed to generate real-world evidence to improve risk stratification, toxicity management, and decision-making regarding immunotherapy continuation or re-initiation.
NCT04375228
The purpose of this study is to examine how effective rituximab or tocilizumab are in treating side effects for people who are receiving immunotherapy treatment requiring prolonged steroid use. Immune-related side effects are caused by the activation of the immune system. Because rituximab and tocilizumab have been shown to effectively in treating other diseased that involve immune system activation, this study seeks to evaluate how effective they will be in treating immune-related side effects in people receiving immunotherapy treatment for cancer.
