Impact of Anti-cytomegalovirus Treatment in the Management of Relapsing Ulcerative Colitis Requiring Vedolizumab Therapy
- Registration Number
- NCT04064697
- Brief 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).
- Detailed Description
The hypothesis of this study is in Ulcerative Colitis (UC) patients with tissue CytoMegaloVirus (CMV) reactivation ; not responding to anti-TNF or without anti-TNF ; a treatment with valganciclovir, added to vedolizumab, could improve the clinical response.

- Primary Outcome Measures
Name Time Method Clinical response Weeks 6 Percentage of patients in clinical response. the clinical response is defined by the decrease in the total Mayo Score compared to the inclusion of at least 3 points and at least 30% with a decrease in the score of bleeding (item 2 of the Mayo sub-score) from at least one point or sub-score of bleeding from 0 or 1 point with or without anti-CMV treatment. The Mayo score includes 3 items: stool frequency, presence of blood in the stool, and overall assessment of the disease.
- Secondary Outcome Measures
Name Time Method Viral load CytoMegaloVirus (CMV) Weeks 6 Value of viral load CytoMegaloVirus (CMV) by qPCR on inflammatory tissue in IU / 100000 cells.
Clinical remission Weeks 6 Percentage of patients in clinical remission defined by a total Mayo score \<3 with an endoscopic score \<2 and no clinical sub-score\> 2.
Mucosal healing Weeks 6 Percentage of patients in mucosal healing defined by endoscopic mayo score \<2
viral load of the Torque teno virus Week 6 performed on the blood tube and tissue biopsies
Rate of colectomy Weeks 52 Percentage of patients who required colectomy
