Treatment of Immune Checkpoint Inhibitor-Related Colitis With Infliximab or Vedolizumab: A Randomized Trial
This phase I/II trial studies the side effects of infliximab and vedolizumab and to see how well they work in treating inflammation of the colon (colitis) caused by immune checkpoint inhibitor therapy in patients with cancer of the genital and urinary organs (genitourinary) or melanoma. Monoclonal antibodies, such as infliximab or vedolizumab, may help to treat immunotherapy induced colitis/diarrhea. This study may help to identify the optimal treatment strategy for immune checkpoint inhibitor-related colitis in patients with genitourinary cancer or melanoma.
• Patients who receive any type of immune checkpoint inhibitor (ICI) therapy
• Patients with peak grade \>= 2 immune-related diarrhea and/or colitis (according to the Common Terminology Criteria for Adverse Events (CTCAE) version 5.0 within 45 days prior to initiation of study treatment (infliximab/ vedolizumab)
• Patients with ability to understand and willingness to sign informed consent
• Patients with genitourinary cancer or melanoma or non-small cell lung cancer
• No concern for active concomitant GI infection for immune-related diarrhea and/or colitis work up at the time of protocol therapy initiation as confirmed by stool tests or as per the treating physician based on clinical presentation
• Patient who has been cleared for enrollment by Infectious Diseases consultant or treating physician if positive infection workup or screening tests (e.g. lifelong positive T-spot due to BCG inoculation, chronic colonization) prior to initiation of diarrhea/colitis treatment
