Tofacitinib Case Reports for Acute Severe UC and Pyoderma Gangrenosum

Two recent case reports indicate that Tofacitinib may be useful in refractory cases of acute severe ulcerative colitis (ASUC) (JA Berinstein et al. Clin Gastroenterol Hepatol 2019; 17: 988-90) and for pyoderma gangrenosum (PG) (B Kochar et al. Clin Gastroenterol Hepatol 2019; 17: 991-93)

The case report for ASUC described 4 patients who received off-label high-intensity tofacitinib.  Initially dosing was 10 mg 3 times a day for 9 doses with subsequent transition to standard dosing.  All four patients had a rapid improvement, though one patient required a colectomy 6 months later and one patient required urgent colectomy after rapid return of symptoms when tofacitinib dose was reduced.

The case report for PG involved 3 patients -two healed with tofacitinib and one improved considerably; the latter patient required dose escalation to 10 mg twice a day.  To understand the mechanism of action further, the authors performed immunohistochemical staining from skin biopsy specimens from two patients and detected “strong staining of phosphorylated JAK-1, phosphorylated JAK-2, phosphorylated JAK-3…in the epidermis.”  Tofacitinib is an oral JAK-1/JAK-3 inhibitor.  In all of these patients, inflammatory arthritis was the indication for tofacitinib.

My take: Due to tofacitinib’s rapid onset of action as well as its rapid clearance, it is a promising agent for both acute severe ulcerative colitis and pyoderma gangrenosum.  More clinical trials are needed.
