Immune reconstitution inflammatory syndrome

This trial tests whether vedolizumab, a drug that calms inflammation in the gut, can prevent diarrhea and colitis caused by immune checkpoint inhibitors. People with advanced melanoma, lung, or kidney cancer who are starting immunotherapy and show early signs of gut inflammation …

This study tests whether ondansetron, a drug typically used for nausea, can lower the risk and severity of side effects from immunotherapy in people with liver cancer. About 134 patients will receive ondansetron alongside their standard cancer treatment. The goal is to see if thi…

This study looks at why some people with HIV develop Immune Reconstitution Inflammatory Syndrome (IRIS) after starting HIV medications. Researchers will use PET scans and lymph node biopsies to track inflammation and immune recovery in 300 adults. The goal is to better understand…

This study follows 700 people with progressive multifocal leukoencephalopathy (PML), a rare brain infection caused by the JC virus. Researchers will collect blood, spinal fluid, and brain scans over time to understand how the disease progresses. No treatment is given; the goal is…

This study aims to understand why some people with tuberculosis (TB) experience a paradoxical reaction, where they initially improve on treatment but then suddenly get worse. Researchers will follow 140 adults with TB, with or without signs of this reaction, using blood tests, ur…

This study looks at how well the immune system recovers its ability to fight cytomegalovirus (CMV) in adults who have had a stem cell transplant. Researchers will measure special immune cells called CMV-specific T cells at several points during standard anti-CMV treatment. The go…

This study follows 200 adults with advanced cancer who are receiving immunotherapy. Researchers will track their physical and emotional distress, financial burden, care needs, and quality of life over one year. The goal is to develop a tool that can predict which patients are at …

This study is a registry that tracks patients with blood diseases who receive stem cell transplants at a hospital on the Qinghai-Tibet Plateau. Researchers will collect information on recovery, complications, and costs over time. The goal is to understand how high altitude affect…
