Efficacy and Safety of Extended Induction With Tofacitinib for the Treatment of Ulcerative Colitis.
Tofacitinib is an oral, small molecule Janus kinase inhibitor for the treatment of ulcerative colitis (UC). The efficacy and safety of tofacitinib were demonstrated in a dose-ranging phase 2 induction trial, 3 phase 3 randomized, placebo-controlled trials (OCTAVE Induction 1 and 2; and OCTAVE Sustain), and an ongoing, open-label, long-term extension trial (OCTAVE Open) in patients with moderately to severely active UC. Here, we assessed short- and long-term efficacy and safety of extended induction (16 weeks) with tofacitinib 10 mg twice daily (BID) in patients who failed to respond to initial induction (8 weeks) treatment. ⋯ Overall, the majority of patients achieved a clinical response after 8 or 16 weeks' induction therapy with tofacitinib 10 mg BID. Tofacitinib 10 mg BID, administered as induction therapy for up to 16 weeks, had a comparable safety profile to 8 weeks' induction therapy. Most delayed responders at Month 36 were in remission. ClinicalTrials.gov: NCT00787202; NCT01465763; NCT01458951; and NCT01470612.

Maintenance of Remission With Tofacitinib Therapy in Patients With Ulcerative Colitis.
Tofacitinib is an oral, small molecule Janus kinase inhibitor for the treatment of ulcerative colitis (UC). The efficacy and safety of tofacitinib in patients with moderate to severe UC, up to 1 year, have been reported. We investigated maintenance of efficacy in patients in remission after 52 weeks of maintenance treatment in the pivotal phase 3 study (OCTAVE Sustain); these patients received open-label, long-term treatment with tofacitinib 5 mg twice daily. ⋯ Efficacy endpoints were maintained for up to 36 months, regardless of prior tofacitinib dose, including patients who reduced from tofacitinib 10 mg to 5 mg twice daily upon OCTAVE Open entry. No new safety risks were identified. ClinicalTrials.gov: OCTAVE Sustain (NCT01458574); OCTAVE Open (NCT01470612).
