Vedolizumab -Not Likely to Help Primary Sclerosing Cholangitis

October 25, 2020 9:00 am

A recent retrospective study (TJ Laborda et al. JPGN 2020; 71: 459-464 Vedolizumab Therapy in Children With Primary Sclerosing Cholangitis: Data From the Pediatric Primary Sclerosing Cholangitis Consortium) indicates that vedolizumab (VDZ) is unlikely to be helpful for primary sclerosing cholangits (PSC).

VDZ was initiated at median age of 16 years [IQR 15–18], 69% were male, 65% had large duct involvement, 19% had (Metavir F3/F4) fibrosis and 59% had ulcerative colitis.

Key findings:

Overall, there was a mild increase in median GGT after initiation of VDZ. Of 32 patients with abnormal GGT at baseline, 22% had a liver biochemical response (defined as GGT <50 or at least a 75% decline) after 9 to 12 months
For IBD, 32% achieved remission, 30% had a clinical response, and 38% had no response

In the discussion, the authors note that their findings are in agreement with three retrospective studies in adults which have shown that VDZ is not effective for PSC in patients with IBD.

My take: This study indicates that VDZ is not likely to help with PSC, though 62% of IBD patients had improvement in their GI disease.
