Infliximab vs Vedolizumab for Colitis from Immunotherapy in Cancer Patients
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial tests two treatments, infliximab and vedolizumab, both monoclonal antibodies, to evaluate their effectiveness in treating colitis, a type of colon inflammation caused by cancer immunotherapy. The research aims to identify the best treatment for this side effect in patients with genitourinary cancers, melanoma, or lung cancer. Suitable participants have experienced serious diarrhea or colitis after using immune checkpoint inhibitors for cancer treatment. Participants will receive either infliximab or vedolizumab through an IV over several weeks to determine which treatment works better with fewer side effects. As a Phase 1, Phase 2 trial, this research focuses on understanding how the treatments work in people and measuring their effectiveness in an initial, smaller group.
Will I have to stop taking my current medications?
The trial does not specify if you need to stop taking your current medications, but you cannot be on other immunosuppressive therapies while participating. It's best to discuss your current medications with the study team.
Is there any evidence suggesting that this trial's treatments are likely to be safe?
Research shows that both infliximab and vedolizumab have promising safety records from past studies.
For infliximab, research on patients with ulcerative colitis indicates it is generally well-tolerated. Patients did not experience more severe side effects than with other treatments like steroids or immune-suppressing drugs. Infliximab's FDA approval for other conditions suggests it is considered safe.
Vedolizumab also has a good safety record. Studies with ulcerative colitis patients show that vedolizumab is effective and safe over the long term. However, some serious infections have been reported in rare cases.
Both treatments have been used in patients with conditions similar to those in this trial, which increases confidence in their safety for treating colitis caused by cancer immunotherapy.12345Why are researchers excited about this trial's treatments?
Most treatments for colitis caused by immunotherapy in cancer patients focus on suppressing the inflammation with corticosteroids. However, Infliximab and Vedolizumab offer different approaches. Infliximab is a monoclonal antibody that targets and blocks tumor necrosis factor-alpha (TNF-alpha), a protein that plays a significant role in inflammation. On the other hand, Vedolizumab is unique because it specifically targets the gut by blocking a protein called integrin, which helps immune cells move into the gut tissue, thereby reducing inflammation selectively in the gut. Researchers are excited about these treatments because they offer targeted options that might lead to fewer side effects compared to traditional systemic immunosuppressants.
What evidence suggests that this trial's treatments could be effective for colitis caused by immunotherapy?
This trial will compare the effectiveness of infliximab and vedolizumab in treating colitis caused by cancer immunotherapy. Research has shown that infliximab, administered to participants in Arm I, has a response rate of about 87%, indicating that most patients experienced an improvement in their colitis symptoms. Vedolizumab, given to participants in Arm II, shows similar results, with about 89% of patients seeing their symptoms disappear. Although both treatments work well, infliximab might have a higher chance of colitis returning. Vedolizumab, however, may help reduce the need for steroids, which often control inflammation. Both treatments appear to be promising options for managing this type of colitis.16789

Are You a Good Fit for This Trial?
This trial is for adults with genitourinary cancer, melanoma, or non-small cell lung cancer who have developed grade 2 or higher colitis from immune checkpoint inhibitor therapy. They must not have active GI infections, inflammatory bowel disease, radiation enterocolitis, or be on other immunosuppressive drugs. Pregnant women and those under 18 are excluded.Inclusion Criteria
