| Sumario: | Background The majority of patients with Crohn's disease (CD) will not achieve endoscopic remission on current therapy. Addition of tofacitinib to biologics may improve remission rates. Methods We retrospectively assessed safety and clinical and endoscopic effectiveness of off-label tofacitinib and biologics for CD. Results We identified 19 patients treated with tofacitinib and a biologic for refractory CD between 2017 and 2019. Tofacitinib was added for luminal disease on colonoscopy (n = 13), luminal disease on capsule (n = 3), and pyoderma gangrenosum (n = 3). The mean age was 41.2 years (28–62), mean disease was duration 16.9 years (6–36), and prior exposure to biologics was a median of 4 (1–6). Mean treatment duration was 9.6 months (SD, 3.3). Adverse events (AEs) were reported in 36.8% of patients, most commonly minor infection or CD flare, and no patients had a serious AE; 80.0% (n = 8) achieved clinical response, and 60.0% (n = 6) achieved clinical remission based on Harvey-Bradshaw Index. Endoscopic improvement occurred in 54.5% (n = 6), endoscopic remission in 18.2% (n = 2), and endoscopic healing in 18.2% (n = 2) of patients. Mean Simple Endoscopic Score in CD significantly improved from 13.6 ± 5.2 to 6.5 ± 4.0 after treatment (P <.01). Conclusions In patients treated with tofacitinib in combination with a biologic, no new safety signals were observed. Combination tofacitinib and a biologic was effective in achieving clinical and endoscopic improvement in some patients with severe, refractory CD, although a larger sample size is needed to further assess the efficacy and long-term safety of this treatment strategy.
