SUMMARYBackground: Heparin has anti-inflammatory and immunomodulatory activity which may be of therapeutic benefit in the treatment of ulcerative colitis. Aim: To test whether low molecular weight heparin, given subcutaneously, would provide a significant therapeutic response compared with placebo in the treatment of mild to moderate ulcerative colitis. Study design: A prospective, double-blind, randomized, placebo-controlled, multi-centre trial comparing tinzaparin 175 anti-Xa IU/kg/day (innohep, LEO Pharma) subcutaneously for 14 days followed by tinzaparin 4500 anti-Xa IU/day subcutaneously for 28 days with placebo, administered subcutaneously once daily for up to 42 days. The primary outcome measure was the mean change in colitis activity from baseline to the end of study treatment assessed by the sum of scores of stool frequency, rectal bleeding, sigmoidoscopic appearance

SUMMARY BackgroundDespite the wide use of azathioprine ⁄ mercaptopurine (AZA ⁄ MP) therapy in the management of both Crohn's disease (CD) and ulcerative colitis (UC), approximately 20% of patients cannot tolerate the drugs and 30% do not respond.

Background Tofacitinib is an oral, small-molecule JAK inhibitor for the treatment of ulcerative colitis (UC). Efficacy and safety of tofacitinib were demonstrated in patients with moderate to severe UC in 3 Phase 3 studies.1 Here, we present data from an ongoing, open-label, long-term extension (OLE) study.2 Methods We present updated safety and efficacy data from the OLE study (OCTAVE Open, NCT01470612; as of May 2019, database not locked). Eligible patients included non-responders (Week 8 data) in OCTAVE Induction 1 and 2 (NCT01465763; NCT01458951) and completers (Week 52 data) or treatment failures (early-termination data) in OCTAVE Sustain (NCT01458574). Patients in remission (total Mayo score ≤2, no individual subscore >1, rectal bleeding [RB] subscore 0) at Week 52 of OCTAVE Sustain (central read) received tofacitinib 5 mg twice daily (BID); all others received 10 mg BID. Induction non-responders without clinical response (≥3-point and ≥30% decrease from induction study baseline total Mayo score, plus ≥1-point RB subscore decrease or absolute RB subscore ≤1) at Month 2 of the OLE study were withdrawn. Incidence rates (IRs) for adverse events (AEs) of special interest were calculated (no. of unique patients with events per 100 patient-years). Efficacy endpoints were derived from Mayo score (local read) with non-responder and last observation carried forward imputation (NRI-LOCF) [a]. Results Of 944 patients who received ≥1 dose of tofacitinib, 769 (81.5%) received 10 mg BID (median duration [range]: 5 mg BID 1170 [36–2066]; 10 mg BID 668 [1–2159] days). In total, 338 (35.8%) and 93 (9.9%) patients discontinued due to insufficient clinical response and AEs (excl. worsening UC), respectively. IRs (95% confidence interval) in the Tofacitinib. All group were: deaths 0.18 (0.05, 0.47); serious infections 1.57 (1.08, 2.19); herpes zoster (non-serious and serious) 3.27 (2.54, 4.14); major adverse cardiovascular events 0.14 (0.03, 0.40); malignancies excl. non-melanoma skin cancer (NMSC) 0.92 (0.56, 1.42); NMSC 0.74 (0.43, 1.21); deep vein thrombosis 0.05 (0.00, 0.25); pulmonary embolism 0.18 (0.05, 0.47) (Table). At Month 36 (NRI-LOCF), 58.9% (n = 103) and 33.5% (n = 257) were in remission, 64.6% (n = 113) and 37.0% (n = 284) had mucosal healing (Mayo endoscopic subscore of 0 or 1) [b] and 66.9% (n = 117) and 40.2% (n = 309) showed clinical response, in the 5 and 10 mg BID groups, respectively. Conclusion Incidence of AEs remained generally consistent in patients with moderate to severe UC in the OLE study compared with a previous analysis.2 Data continue to support long-term efficacy with tofacitinib up to 36 months beyond Week 52 of OCTAVE Sustain.
