Treatment of antibiotic refractory chronic pouchitis with JAK inhibitors and S1P receptor modulators: an ECCO CONFER Multicentre Case Series.

BACKGROUND AND AIMS

Data regarding effectiveness and safety of JAK inhibitors and S1P receptor modulators in antibiotic refractory chronic pouchitis (CARP) are lacking.

METHODS

This ECCO-CONFER project retrospectively collected JAK inhibitors or S1P receptor modulators treatments for CARP with at least 3-months follow up. The outcomes included corticosteroid and antibiotics-free clinical response and remission at three and twelve months, trend in mPDAI, endoscopic PDAI, CRP and calprotectin.

RESULTS

Seventeen treatments in 15 patients were collected. Previous pouchitis treatments included infliximab (5/15), adalimumab (4/15), vedolizumab (9/15), and ustekinumab (5/15). Pooling data on JAK inhibitors (8 tofacitinib, 1 filgotinib and 6 upadacitinib), after 3 months (T3), steroid and antibiotics-free clinical response was achieved in 53.3% (8/15), steroid and antibiotics-free clinical remission was achieved in 40% (6/15). Of the patients with at least 12 months of follow-up, steroid and antibiotics-free clinical response was achieved in 50% (3/6) and remission in one patient (16.7%), endoscopic response in 50% (3/6), endoscopic remission in 50% (3/6). Of the two ozanimod treatments at T3, steroid and antibiotics-free clinical response was achieved in one patient, without remission; both discontinued ozanimod before T12. No side effects reported.

CONCLUSIONS

Small molecules may represent a suitable option for CARP refractory to multiple biologics, deserving further investigation.
