Tofacitinib Outperformed Vedolizumab in Anti-TNF-experienced Ulcerative Colitis

T Straamijer et al. Clin Gastroenterol Hepatol 2023; 21: 182-191. Open Access! Superior Effectiveness of Tofacitinib Compared to Vedolizumab in Anti-TNF-experienced Ulcerative Colitis Patients: A Nationwide Dutch Registry Study

Methods: Adults with ulcerative colitis (UC) previously who failed anti-TNF treatment and initiated vedolizumab (n=83) or tofacitinib (n=65) treatment were identified in the Initiative on Crohn and Colitis Registry in the Netherlands.

Key findings (Vedolizumab is in gray):

  • There was no difference in infection rate or severe adverse events.

My take: Coupled with more recent reassuring safety data on JAK inhibitors, this study makes a strong case for positioning Tofacitinib (or other JAK inhibitor) earlier in patients with moderate-to-severe ulcerative colitis. Given that vedolizumab outperformed adalimumab in a head-to-head study, this indicates that tofacitinib is a very effective therapy.

The week 8 clinical remission rate was 22%-24% in the treatment groups compared to 5% in the placebo group.
