Phase 4 Interventional The First Affiliated Hospital of Soochow University · NCT06066840

This study is testing a new combination treatment for adults with severe acute graft-versus-host disease who haven't improved with steroids to see if it helps them feel better.

What this trial studies

This clinical trial investigates the efficacy and safety of vedolizumab and an anti-CD25 monoclonal antibody in treating grade 3-4 steroid-refractory acute graft-versus-host disease (SR-aGVHD) with gastrointestinal involvement. Participants aged 18-65 who have not responded to systemic steroids will receive a combination therapy of vedolizumab and basiliximab, with a rapid reduction of glucocorticoids. The study aims to assess the treatment's effectiveness in improving patient outcomes and managing symptoms associated with this severe condition.

Who should consider this trial

Good fit: Ideal candidates for this study are adults aged 18-65 diagnosed with grade 3-4 steroid-refractory acute graft-versus-host disease with gastrointestinal involvement.

Not a fit: Patients with refractory graft-versus-host disease, severe complications, or those with a life expectancy of less than 60 days may not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could provide a new therapeutic option for patients suffering from severe SR-aGVHD, potentially improving their quality of life and survival rates.

How similar studies have performed: While there have been studies on treatments for aGVHD, this specific combination therapy approach is novel and has not been extensively tested.
