Summary: The purpose of this study is to estimate and compare the incidence of overall malignancy, serious infection, and opportunistic infections between new users of ustekinumab and new users of other biologic therapies among adult participants with Crohn's disease (CD) or ulcerative colitis (UC).

Summary: Immune-related colitis from immune checkpoint inhibitors (ICI) is a common adverse effect causing significant morbidity and impairment of quality of life (QoL). Steroids are the first line of treatment for severe ICI induced Immune- mediated diarrhea and colitis (IMDC). If there is no improvement in 48 to 72 hours, other immunosuppressive agents (infliximab, vedolizumab) are recommended. However, ...

Summary: The goal of this clinical trial is to compare the safety and effectiveness of infliximab compared to steroids for the treatment of immune checkpoint inhibitor-induced colitis (ICI colitis) in patients with stage III/IV skin cancer. The main questions this study aims to answer are: * How many patients treated with infliximab experience steroid-free disease resolution after 7 weeks? * How many patie...

Summary: Open label pragmatic two-stage non-randomized trial comparing the effectiveness of five different standard of care treatment options for patients with relapsing polychondritis (RP).

Summary: This trial studies the role of the gut microbiome and effectiveness of a fecal transplant on medication-induced gastrointestinal (GI) complications in patients with melanoma or genitourinary cancer. The gut microbiome (the bacteria and microorganisms that live in the digestive system) may affect whether or not someone develops colitis (inflammation of the intestines) during cancer treatment with i...

Summary: This is a randomized, double-blind, placebo-controlled, two-arm phase 2 study of etrasimod plus corticosteroids versus placebo plus corticosteroids for the treatment of IMDC CTCAE v5.0 grade ≥ 2 due to ICI therapy alone (α-PD-(L)1 monotherapy or combined with another ICI, such as α-CTLA-4 or α-LAG-3) or ICI plus an oral tyrosine kinase inhibitor that in the opinion of the treating physician requir...

Summary: This study evaluates the effectiveness and safety of infliximab in the treatment of acute pancreatitis in adults. A third of participants will receive one single dose of infliximab via infusion, another third will receive a higher dose of infliximab via infusion and the final third of participants will receive a placebo infusion.

Summary: The purpose of this research is to test the safety and effectiveness of the investigational combination of anti-Programmed Death (PD)-1 antibody therapy with or without LAG-3 inhibition (pembrolizumab or nivolumab+relatlimab) and infliximab in treating metastatic melanoma.

Summary: The goal of this clinical trial is to evaluate the effect of supplementing Bacillus subtilis compared to the control group on the efficacy of Infliximab in patients with Crohn's disease, and to summarize the role of supplementing Bacillus subtilis in the treatment of CD patients. Participants will be randomized into two groups: the Bacillus subtilis supplementation group and the control group. The...

Summary: Crohn's disease (CD) is a chronic inflammatory bowel disease. CD pathogenesis remains poorly understood but involves an inappropriate immune response toward an unbalanced gut microbiota in predisposed hosts. The purpose of this study is to evaluate de clinical efficacy of the fecal microbiota transplantation (FMT) as a maintenance treatment following anti-TNF agent withdrawal in CD's patient.

Summary: Rheumatoid arthritis (RA) is a common disease with approximately 1% prevalence. RA is also a chronic, progressive disease with no cure. Current treatment goals are to minimize pain, limit joint damage, and prevent loss of function. Drugs used to treat RA include non-steroidal anti-inflammatory drugs (NSAIDS), glucocorticoids, and disease-modifying anti-rheumatic drugs (DMARDs), including biologics...

Summary: The purpose of this trial is the comparative evaluation of overall response rate (ORR) in paediatric participants with steroid-refractory acute graft-versus-host disease (SR-aGvHD) at Visit Day 28 after treatment with MC0518 or first used best available therapy (BAT).
