Impact of Anti-cytomegalovirus Treatment in the Management of Relapsing Ulcerative Colitis Requiring Vedolizumab Therapy

• Status: Recruiting
• Trial end date: 2023-07-01
• Target enrollment: 0
• Participant gender: All

Summary

Ulcerative Colitis (UC) is an inflammatory bowel disease that can require the use of anti-TNF alpha therapy. When anti-TNF alpha failed to obtain a clinical response, the use of a new anti-integrin therapy, vedolizumab, can be proposed. The efficacy of vedolizumab has been assessed in a phase 3 study (GEMINI I), with response rates of 41.1% with vedolizumab vs 25.5% with placebo.

CytoMegaloVirus (CMV) reactivation has been associated with resistance to steroid and to several lines of immunosuppressive therapy. Antiviral therapy was proven to decrease the tissue viral load and to restore the response to immunosuppressive therapies (up to 80% in small group of patients). A recent meta-analysis supports the use of valganciclovir in case of CytoMegaloVirus (CMV) reactivation in active Ulcerative Colitis (UC).

Moreover, a study showed that the risk of CMV reactivation seems to be more important with vedolizumab than with anti TNF, and the risk of colectomy is higher in case of CytoMegaloVirus (CMV) reactivation (p<0.05).
