AIM: to demonstrate the first Russian experience with the use of tofaciminib (TOFA) for the treatment of moderate and severe UC in real clinical practice.PATIENTS AND METHODS: eighty-five patients with UC (aged 41.38±14.69 years, average disease duration 9.55±5.27 years, mild UC – 3.5%, moderate UC – 41.2%, severe – 52.9%, acute severe UC – 2.6%), resistant to corticosteroid therapy (36.5%) and biological agents (61.2%), were prescribed with TOFA at an induction dose of 10 mg 2 times a day, followed by a decrease in the dose to a maintenance dose (5 mg 2 times a day). Early clinical response, clinical and endoscopic remission, prevalence and dynamic of extraintestinal manifestations were assessed at 8 and 12 weeks of treatment, as well as safety and tolerability.RESULTS: Sixty-eight (80.0%) patients completed induction treatment with TOFA for 8 weeks, other patients continue to receive TOFA. A quick response within one week was detected in 41 (50.6%) patients, on average, on the 5th day of therapy. At the end of induction, 52 (76.5%) patients achieved clinical remission, 3 (4.4%) achieved a clinical response, 13 (19.1%) patients showed no positive changes. Of the 53 patients observed over 12 weeks, 41 (77.4%) had clinical remission, 6 (11.3%) had clinical improvement, and 6 (11.3%) patients had no response to the treatment. The changes of extraintestinal manifestations were positive: 55.2% of patients at week 8 and 77.8% of patients at week 12 showed clinical improvement, mainly in relation to the joint syndrome. One episode of herpes zoster infection, one case of anemia, were identified dur-ing 12 weeks of follow-up.CONCLUSION: TOFA in UC is effective in achieving a rapid clinical response, clinical remission and mucosal healing in patients who do not adequately respond to therapy with basic as well as biological drugs. Tofacitinib is an effective and safe therapeutic option for this challenging patient population.

Introduction. Tofacitinib is the first member of a new class of targeted synthetic anti-inflammatory drugs for the treatment of ulcerative colitis (UC). The article presents a three-year Russian experience of tofacitinib use for the treatment of moderate and severe UC.Aim of the study. To evaluate the efficacy and safety of tofacitinib therapy in real clinical practice in moderate to severe UC patients during three years of follow-up.  Methods. The study included 56 patients with UC who had moderate (60.7%) and severe (35.8%) states of disease, the total lesion was diagnosed in 67.8%, and extraintestinal manifestations in 57.1% of patients. Early achievement of clinical response, clinical and endoscopic, corticosteroid-free remission, and safety were evaluated.Results. Early response to tofacitinib therapy was obtained in 47 (83.9%) patients. Clinical remission was achieved in 36 (64.3%) at week 8 of therapy and clinical response was achieved in 13 (23.2%) patients. The majority of patients who achieved clinical remission at weeks 8 and 12 achieved healing of colon mucosa at week 24. Clinical and endoscopic remission rates after 24 weeks – 44 (78.6%) patients, clinical response in 7 (12.5%) patients, 5 (8.9%) did not respond to TFCB therapy. Corticosteroidfree remission was 77.6%. After 2 years of tofacitinib therapy, remission of UC was maintained in 46 (82.1%). After 36 months, remission of UC was maintained in 45 (80.3%) of the 56 patients who had been started on tofacitinib therapy. The cumulative effect of survival in the treatment of tofacitinib in UC was 87.5% after 6 months and persisted for one year, 82.1% after 2 years, and 80.3% after 3 years.Conclusions. The administration of tofacitinib in UC is effective in achieving rapid clinical response, clinical remission, and mucosal healing in patients who do not respond well to biological therapy.

Vedolizumab is currently the only selective biological drug for the treatment of inflammatory bowel diseases (IBD). Its effectiveness and safety has been shown in clinical trials. This article presents the experience of using vedolizumab in real clinical practice in patients with various forms of ulcerative colitis (UC) and Crohns disease (CD). Materials and methods.96 patients with IBD (62 with CD and 34 with UC) were prescribed therapy with vedolizumab at a dose of 300 mg intravenously at 0, 2, and 6 weeks, and further maintenance therapy was continued every 8 weeks. Most patients had prolonged inflammation (27 (79.4%) with total UC, 35 patients with CD (56.5%) had ileocolitis), resistance to therapy, including biological drugs (19 (55.9%) in patients with UC and 49 (79.0%) in patients with CD). The effectiveness of therapy was evaluated after 3 months (based on clinical response and clinical remission), 6 and 12 months (endoscopic response and endoscopic remission were additionally evaluated). Results.After 3 months, clinical remission was observed in 62.5% and 36.6%, respectively. After 6 months, these indicators were 66.7% and 61.0%, and after 12 months, 70.8% and 61.0%, respectively. After 6 months, endoscopic remission was observed in 50.0% of UC patients and 26.8% of CD patients. After 12 months, it reached 58.3% and 31.7%, respectively. The analysis showed greater efficacy in bio-naive patients with CD (steroid-free remission after 12 months 62.5%, endoscopic remission 37.5%), as well as patients with non-stricturizing non-penetrating CD (58%). In patients with UC, vedolizumab showed the same effectiveness both in bio-naive patients (70.0%) and as a second-line therapy (71.2%). It turned out to be more effective in patients with moderate UC (76.2%) and steroid-dependent UC (77.8%). Conclusions.Vedolizumab is effective in achieving clinical response and clinical remission, as well as endoscopic response and endoscopic remission in patients with UC and CD. Given the selective mechanism of action of the drug, it can be recommended as a first-line therapy.

Abstract Background Current therapeutic goals in inflammatory bowel disease (IBD) include not only the mere absence of symptoms but also the resolution of endoscopic lesions, so-called mucosal healing (MH), which has been related to better outcomes. Data regarding the achievement of MH with vedolizumab (VDZ) in real-life clinical practice is still scarce. Methods Retrospective cohort study was carried out in a tertiary hospital between January 2015 and April 2019 including patients with a basal colonoscopy showing activity and who achieved clinical remission under treatment with VDZ, defined by partial Mayo score <2 for ulcerative colitis (UC) and Harvey–Bradshaw Index score (HBI) <4 for Crohn’s disease (CD). Surveillance colonoscopy was performed along with the follow-up according to clinical practice. In UC patients, MH was defined as Mayo Endoscopic Subscore (MES) = 0; the endoscopic response was defined by a decrease in MES ≥1 point. In CD, MH was defined by achievement SES-CD = 0–3 or Rutgeerts index i0; the endoscopic response was defined by a decrease of SES-CD of 50% or Rutgeerts index <i2 with at least 1 point of decease compared with baseline. Results In total, 118 patients treated with VDZ were analysed, but only 45 met inclusion criteria with a median follow-up of 21 (IQR: 14–19) months. Surveillance colonoscopy was performed after a median time of 12 months (IQR:9–17) of treatment. MH achieved in 33/45 patients (73%): 17/23 CD patients (74%) and 16/22 UC patients (73%). The endoscopic response was achieved in 9 of the remaining 12 patients: 3/6 CD patients and 6/6 UC patients. Only 3 (7%) of patients included showed no endoscopic benefit at the time of surveillance endoscopy. In multivariate analysis, probability of not achieving MH was 75% in patients previously treated with immunosuppressants (ISS) (HR 0.25, 0.11–0.55 IC95; p = 0.001) and 60% in patients previously treated with anti-TNFα (HR 0.40, 0.18–0.90 95% CI; p = 0.026). Type of IBD, concomitant ISS, corticosteroid use at induction, baseline endoscopy score or duration of disease before VDZ treatment were not associated with the achievement of MH. Conclusion In our experience, most of the patients who achieve clinical remission with VDZ also achieve MH. Refractory patients were less likely to achieve MH despite having achieved clinical remission.

AbstractObjective: To determine the effect on clinical response to clozapine of increasing the plasma levels of clozapine and its major metabolite N-desmethylclozapine in 19 patients with schizophrenia who had plasma clozapine levels ≤ 370ng/ml, a level previously determined to identify patients who were unlikely to have an adequate response to clozapine.Method: The dosage of clozapine was increased by 20% in 11 patients and left unaltered in the other eight patients. Clozapine and N-desmethylclozapine plasma levels were measured after six weeks at the higher dose.Results: Nine of the 11 patients in whom clozapine dosage was increased subsequently achieved plasma clozapine levels ≥ 370ng/ml. However, in this group of patients who already had partially responded to clozapine, increasing the dosage of clozapine did not produce additional clinical improvement.Conclusion: Clozapine plasma levels are useful in clinical practice to guide dosage strategies. However, these results suggest that increasing the dosage of clozapine to achieve plasma levels ≥ 370ng/ml is unlikely to produce further improvement in patients who have already achieved a partial response to clozapine at plasma levels ≤ 370ng/ml.

Background and Aims: Several studies have found Golimumab (GOL) effective and safe in the short-term treatment of ulcerative colitis (UC), but few long-term data are currently available from real world. Our aim was to assess the long-term real-life efficacy and safety of GOL in managing UC outpatients in Italy. Methods: A retrospective multicenter study assessing consecutive UC outpatients treated with GOL for at least 3-month of follow-up was made. Primary endpoints were the induction and maintenance of remission in UC, defined as Mayo score ≤2. Several secondary endpoints, including clinical response, colectomy rate, steroid free remission and mucosal healing, were also assessed during the follow-up. Results: One hundred and seventy-eight patients were enrolled and followed up for a median (IQR) time of 9 (3-18) months (mean time follow-up: 33.1±13 months). Clinical remission was achieved in 57 (32.1%) patients: these patients continued with GOL, but only 6 patients (3.4%) were still under clinical remission with GOL at the 42nd month of follow-up. Clinical response occurred in 64 (36.4%) patients; colectomy was performed in 8 (7.8%) patients, all of them having primary failure. Steroid-free remission occurred in 23 (12.9%) patients, and mucosal healing was achieved in 29/89 (32.6%) patients. Adverse events occurred in 14 (7.9%) patients. Conclusions: Golimumab does not seem able to maintain long-term remission in UC in real life. The safety profile was good.

Abstract Background Evidence suggests that early treatment (Tx) with biologic agents in Crohn’s disease improves long-term clinical outcomes. However, there is less evidence in ulcerative colitis (UC), and data comparing early Tx with first-line biologic vedolizumab (VDZ) to anti-tumour necrosis factor (anti-TNF) in real-world settings is needed. This study compared the clinical effectiveness and safety of UC patients who initiated VDZ or an anti-TNF as a first-line biologic within 2 years following diagnosis. Methods This was a real-world, multi-country, retrospective chart review study in Canada, Greece and the United States where biologic-naïve UC patients (≥18 years old) were treated with VDZ or an anti-TNF (adalimumab, infliximab, golimumab) agent within 2 years following diagnosis (initiated Tx May 2014–March 2018). Clinical effectiveness and safety data were collected from Tx initiation to earliest of chart abstraction date, death, or 6 months post-Tx discontinuation (Canada only). Tx persistence was defined as the duration of time from treatment initiation to discontinuation. Analyses of cumulative rates of Tx persistence, clinical response, clinical remission and mucosal healing over 24 months were estimated using Kaplan–Meier analyses. Clinical response, remission and mucosal healing were assessed using pre-defined hierarchical algorithms of standard disease measures reported in the medical records. Analyses of incidence rates (per 100 person-years [PYs]) of disease exacerbations, disease-related surgeries, serious adverse events (SAEs) and serious infections (SIs) were performed. Adjusted analyses used inverse probability weighting to balance cohorts. Results This analysis included 176 UC patients (VDZ: 86; anti-TNF: 90) from 37 sites. Mean (SD) age at index date: VDZ, 41.4 (18.9); anti-TNF, 36.8 (15.6) years (p = 0.20) and the proportion male: VDZ, 58.1%; anti-TNF, 56.7% (p = 0.84). At 12 months, 72.9% and 58.1% continued VDZ and anti-TNF respectively (p = 0.03) (Figure 1A). Though there were no differences in clinical response, clinical remission or mucosal healing between VDZ and anti-TNF groups; VDZ patients were significantly less likely to experience disease exacerbations (HR = 0.47 [95% CI: 0.32–0.69]) and SAEs (HR = 0.37 [95% CI: 0.19–0.72]) (Figure 2). Adjusted outcomes (Figures 1C and D, and 2B) were similar to unadjusted outcomes. Conclusion EVOLVE is one of the first studies that compared early VDZ Tx to early anti-TNF Tx in biologic-naïve UC patients. Results showed VDZ was associated with higher persistence, lower likelihood of experiencing disease exacerbations and a more favourable safety profile. Thus, in early UC, Tx with VDZ may improve long-term clinical outcomes. Sample size limitations warrant further study.

Abstract Background and Aims In nonresponders to golimumab induction for ulcerative colitis, we assessed clinical response rates and golimumab serum concentrations when the 100-mg dose was used early in the course of maintenance. Methods This post-hoc analysis of golimumab maintenance dosing [in the PURSUIT-M study] examined clinical outcomes and golimumab concentrations in early [Week 6] responders and nonresponders to induction, including subgroups based on body weight. Results In nonresponders to golimumab induction [assessed at Week 6], the 100-mg maintenance dose [starting at Week 6] resulted in a meaningful proportion [28.1%] of patients achieving a partial Mayo response at Week 14. After 1 year of maintenance, clinical outcome [response, remission, mucosal healing, corticosteroid-free state] rates in these “late” [Week 14] responders were similar to those in early [Week 6] responders. Golimumab concentrations in early nonresponders were approximately half those of early responders, suggesting that early nonresponders had more rapid golimumab clearance. Examined by body weight, the early nonresponders weighing <80 kg and receiving 100 mg had golimumab concentrations similar to the early responders [weighing <80 kg or ≥80 kg and receiving 50 mg or 100 mg, respectively]. Conclusions Early use of the 100-mg maintenance dose leads to positive clinical outcomes in a meaningful proportion of patients who did not respond to golimumab at Week 6. Early nonresponders <80 kg who received the 100-mg maintenance dose achieved adequate golimumab concentrations and a clinically meaningful proportion of these patients had a late clinical response.

Abstract Introduction Ontamalimab is a fully human immunoglobulin G2 monoclonal antibody against mucosal addressin cell adhesion molecule-1 in development for the induction and maintenance of clinical remission in patients with ulcerative colitis (UC). This study aimed to assess the long-term pharmacokinetics (PK) of ontamalimab in patients with UC, and the effects of concomitant medications on PK parameters. Methods A 12-week induction study (TURANDOT; NCT01620255) was performed to assess the PK, efficacy and safety of ontamalimab (7.5, 22.5, 75 and 225 mg subcutaneous [s.c.] every four weeks [Q4W]) in patients with UC. Individuals who completed the induction study were eligible for enrollment in an open-label extension (OLE) study (TURANDOT II; NCT01771809) to assess the long-term PK, efficacy and safety of ontamalimab (75 or 225 mg s.c. Q4W up to week 72). Population PK analyses were performed using nonlinear mixed-effects modelling. Exposure-response analyses were performed to assess the relationships between minimum concentration (Cmin,ss) of ontamalimab and clinical response, clinical remission and mucosal healing. The effect of concomitant treatments (used for ≥20% of treatment duration) on PK parameters was also evaluated. Results The PK population included 130 (39.8%) women and 197 (60.2%) men, of median age of 40 years. A 1-compartment model with linear elimination adequately described the PK of ontamalimab. Population estimates of apparent clearance (CL/F) and volume of distribution (V/F) were 0.00917 L/h (0.22 L/day) and 7.44 L, respectively. Albumin had a significant effect on the variability of CL/F. Individuals with albumin levels of 30 g/L and 47 g/L are expected to have CL/F values 44% higher and 23% lower, respectively, than a typical patient with an albumin level of 39 g/L. Anti-inflammatory agents affected CL/F, such that CL/F is expected to be 14% higher in patients receiving than not receiving these agents. Other medications including immunosuppressants, steroids and treatments for peptic ulcers and gastroesophageal reflux disease had no effect on CL/F. Weight was the only covariate that significantly affected V/F. The half-life of ontamalimab was 23.4 days. Concentrations of ontamalimab over 72 weeks in the OLE study were consistent with those observed in the 12-week induction study. Ontamalimab Cmin,ss was related to efficacy, such that at week 16 (week 28 in total including induction), patients with higher Cmin,ss values were more likely to have clinical response, clinical remission and mucosal healing than those with lower Cmin,ss. Conclusion The exposure to ontamalimab was sustained following prolonged treatment in patients with UC for up to 72 weeks. Higher ontamalimab exposure was associated with a higher probability of clinical response.
