BACKGROUND The anti-TNF drugs are shown to be highly effective in treatment of patients with moderate-tosevere inflammatory bowel disease (IBD). Here, we aimed to assess the efficacy and safety of antiTNF therapy at the national level. METHODS IBD patients aged 15 > years who received Infliximab and/or CinnoRA® between 2013 to July 2018 were identified. The data extracted from medical dossier and telephonic interview. The efficacy of therapy was defined as time to drug discontinuation or need for IBD-related surgery. The safety was assessed based on patient’s reported adverse events. RESULTS We included 315 patients. The mean age of patients was 37.2 years and 62.2% of them developed the disease before age 30 years. Involvement of masculoskeletal system was reported in 7.3% of patients. Partial and complete response to Anti-TNF therapy was seen in 67% of patients. About 16% of patients did not respond to induction therapy and 16.9% of patients lost their response to Anti-TNF during one year. No serious adverse events, serious opportunistic infection, tuberculosis and malignancies reported by patients. Two patients reported pneumonia. CONCLUSION This study for the first time in our country, provides the evidences for efficacy of anti-TNF therapy in moderate to severe IBD patients.

Abstract Background Few reports of the real-world efficacy and safety of tofacitinib (TFB) in Asians are available, and potential predictors of the response to therapy are unclear. We investigated the efficacy and safety profiles of TFB treatment for one year in patients with active Ulcerative Colitis (UC) in our specialized Inflammatory Bowel Disease center. Methods This study included 111 patients who received TFB between May 2018 and February 2020. We assessed disease activity using the partial Mayo Score (pMS). Clinical remission was defined as pMS ≤2, with no subscore >1 and a rectal bleeding subscore of 0. Clinical response was defined as a decrease in pMS of ≥2 points from baseline with an accompanying decrease in the rectal bleeding subscore of ≥1 point or an absolute rectal bleeding subscore of ≤1 point. Results Mean patient age was 35 years (interquartile range [IQR]: 28-47), 60 (59.4%) were men, and mean disease duration was 4.8 years (IQR:1.5-10). The pMS was 6 (IQR:4-7) and C-reactive protein was 0.30 mg/dl (IQR: 0.1-1.0). At baseline, 63 (62.4%) patients received an anti-TNFα agent, 11 (10.9%) received vedolizumab, and 7 (6.9%) received both. Clinical response and clinical remission were, respectively, 66.3% (67/101) and 50.5% (51/101) at week 8, and 47.1% (40/85) and 43.5% (37/85) at week 48. The cumulative remission rate was 61.7% at 1 year and 51.7% at 2 years, and tended to be better in the ≥2 anti-TNFα agents failure group than in the 1 anti-TNFα agent failure and bio-naïve groups (P=0.10). Cumulative colectomy-free survival was 91.9% at 1 year and 89.1% at 2 years. Cumulative drug-free survival in the non-remission group at week 8 was 30.9% at 1 year and 30.9% at 2 years, significantly lower than in the remission-achieving group at week 8 (P<0.01). Baseline pMS was significantly lower in responders vs non-responders at week 8 (odds ratio, 0.61; 95% confidence interval, 0.45-0.82). Relapse occurred in 45.7% of patients after tapering TFB, and 85.7% of patients with re-increased TFB responded by week 4. Herpes zoster occurred in 6 unvaccinated patients (46±16 years old). There were no specific features regarding age, TFB dosage, duration of administration, or lymphocyte count in these patients. No thrombotic adverse events occurred, even though 54.1% patients continued treatment with 10 mg twice daily at week 48. Conclusion TFB was more effective in low-activity UC patients and its efficacy was not affected by previous treatment with anti-TNF agents. Most patients in the remission groups at week 8 could continue TFB for one year without severe adverse events, although careful monitoring for herpes zoster is necessary. The risk of thrombotic adverse events might be lower in Japanese UC patients.

Abstract Backgrounds and Aims We aimed to evaluate the safety of Bacille Calmette–Guérin [BCG] vaccination in infants born to mothers receiving anti-tumour necrosis factor [anti-TNF] therapy for inflammatory bowel disease. Methods Adverse events of BCG vaccination were evaluated in 90 infants who were last exposed to anti-TNF agents at a median of gestational week 30. Results After receiving BCG vaccination at a median age of 6 months [range, 0.25–11 months], three infants [3.3%] showed injection site swelling, two of whom also showed axillar lymphadenopathy. The rates of adverse events were similar between infants who were last exposed to anti-TNF agents before the third trimester [n = 35] and those who were last exposed in the third trimester [n = 55] [2.9% vs 3.6%; p = 1.00]. All adverse events were spontaneously resolved and there were no serious adverse events such as active tuberculosis infection or death. Conclusions BCG vaccination after 6 months of age is of low risk in infants exposed to anti-TNF agents in utero.

Background: Long-term data on inflammatory bowel disease (IBD) patients switched from originator to biosimilar infliximab SB2 are lacking. The aim of the conducted study was to investigate the effectiveness, immunogenicity and safety of a large prospectively followed-up IBD patient cohort that was entirely switched from originator infliximab to biosimilar SB2 treatment. Methods: This was a prospective, single-center, longitudinal, observational study describing clinical outcomes in IBD patients, over an 80-week period following switch from originator infliximab to SB2. Primary outcome measures were change of disease activity [Harvey-Bradshaw Index for Crohn’s disease (CD), partial Mayo Score for ulcerative colitis (UC)], C-reactive protein (CRP), infliximab trough levels (TLs), anti-drug antibodies (ADAs) and adverse events. Results: One hundred and forty-four IBD patients (94 CD, 50 UC), with median duration of 30.5 months’ (range 2–110) treatment with originator infliximab were evaluated. Mean change of disease activity compared with baseline was −0.9 (SD 2.6), –0.4 (2.2) and –0.4 (2.0) in CD; 0.1 (1.1), 0.1 (1.1) and 0.1 (1.3) in UC patients at weeks 24, 48 and 72. Median infliximab TLs were 6.2 µg/ml (interquartile range 2.3–12.2), 5.0 µg/ml (2.7–10.0), 6.6 µg/ml (3.5–12.4) and 5.1 µg/ml (2.7–10.9) at baseline and weeks 24, 48 and 72. Median CRP levels were within normal ranges throughout the study. After the switch, 9.8% of the patients developed new ADAs. Persistence on SB2 was 90% (95% confidence interval 0.85–0.95), 79% (0.72–0.86), 72% (0.64–0.80) at weeks 26, 52 and 78. Serious adverse events occurred in 11 patients. Conclusion: Over the individual patient follow-up of 80 weeks, switch to biosimilar SB2 from originator infliximab does not result in increased disease activity or changed immunogenicity patterns. The switch to SB2 was well tolerated.

Abstract Background SB2 is a biosimilar infliximab approved for the treatment of inflammatory bowel disease (IBD) patients. These are the first prospective data investigating long-term efficacy, safety, and pharmacokinetics after switching from infliximab originator to biosimilar SB2 in IBD patients. Methods This is a prospective, observational cohort study of patients that underwent a switch from infliximab originator to biosimilar SB2 in 2017 as part of routine care at the outpatient Clinic for IBD at the University Hospital of Erlangen, Germany. Long-term safety and clinical effectiveness were recorded over a follow-up period of 18-months. Clinical disease activity was assessed by the Harvey–Bradshaw Index (HBI) in Crohn’s disease (CD) and the partial Mayo Score (pMS) in ulcerative colitis (UC) patients. C-reactive protein (CRP) was analyzed at every patient visit, and IFX trough-level (TL) and anti-IFX antibodies (ADA) were measured prior to every SB2 administration, using the Promonitor® tests. The occurrence of adverse events was registered at every patient visit. Results A total of 148 IBD patients (96 CD, 52 UC) was enrolled. The median duration of previous infliximab treatment before the switch was 29 months (range 1.0–110.0). Median disease activity in CD was an HBI of 3 (0–16) at switch (baseline), 2 (0–13) at month 6, 3 (0–15) at month 12 and 2.5 (0–11) at month 18. Median disease activity in UC was a pMS of 0 (0–6) at baseline, 1 (0–4) at month 6, 1 (0–4) at month 12 and 1 (0–5) at month 18. The median TL for all IBD patients was 6.3 mg/ml (0.1–33.7) at baseline, 5.0 mg/ml (0.1–34.3) at month 6, 6.3 mg/ml (0.1–35.8) at month 12 and 5.1 mg/ml (0.1–35.4) at month 18. CRP for all IBD patients was 2.2 mg/l (0.1–45.6) at baseline, 2.2 mg/l (0.1–90.4) at month 6, 2.3 mg/l (0.1–169.5) at month 12 and 2.7 mg/l (0.1–19.8) at month 18. In the 18-month follow-up period, 12/103 (11.7%) of patients who were ADA-negative at baseline developed ADA post-switch. Altogether, 40 (27%) IBD patients discontinued SB2 treatment during the 18-month follow-up period (4 anaphylaxis, 20 loss of response, 7 non-serious and 9 serious adverse events), 2 paused during pregnancy, 1 discontinued in clinical remission, 10 were lost to follow-up (7 change of physician, 3 unknown). Serious adverse events comprised 3 malignancies (breast and prostate carcinoma, neuroendocrine malignancy), 1 liver abscess and 5 intestinal surgical procedures (1 perforation, 1 ileus, and 3 stenoses). Conclusion Switching from IFX originator to biosimilar SB2 was not associated with an increase in disease activity. No clinically meaningful changes in IFX trough levels or immunogenicity were identified. Altogether, SB2 was well tolerated in a real-life setting.

ABSTRACT BACKGROUND: Biologics have revolutionized the treatment of inflammatory bowel disease (IBD). However, these drugs had a significant influence on treatment-related costs, which resulted in the development of biosimilars. OBJECTIVE: This systematic review and meta-analysis aimed to evaluate the drug discontinuation rate in the IBD population who switched from originator to biosimilars in real-world switching studies and address potential nocebo effects as reasons for drug discontinuation. METHODS: Medline (via PubMed), EMBASE, Cochrane Library, and abstract databases of selected congresses were screened for reports of monoclonal antibody (mAb) switching with a minimum post-switch follow-up of >6 months or three infusions. All available information on discontinuation rates was assessed. RESULTS: A total of 30 observational studies were included, involving 3,594 patients with IBD. Twenty-six studies reported a switch from infliximab to CT-P13, two studies involved a switch to SB2, and switching information was not available in two studies. The discontinuation rates were 8%, 14%, and 21% at 6, 12, and 24 months, respectively. The main reasons for drug discontinuation and their respective risks were: disease worsening (2%), remission (4%), loss of adherence (4%), adverse events (5%), and loss of response (7%). The quality of the evidence ranged from low to very low depending on the outcome analyzed. Subjective symptoms leading to drug discontinuation were infrequently reported, and the nocebo effect was clearly assessed in just one of the included papers. CONCLUSION: Discontinuation rates following a switch to a biosimilar in patients with IBD increase over time. However, it was not possible to confirm the nocebo effect as a reason for discontinuation. Therefore, long-term studies evaluating the use of biosimilars to monitor adverse events and potential nocebo effects in post-marketing surveillance are still needed.

Abstract Background Quality of life (QoL) data for patients with inflammatory bowel disease switched from the reference infliximab to biosimilar CT-P13 is lacking. This study aims to demonstrate non-inferiority for QoL and efficacy after switching. Methods OoL and clinical efficacy were measured prior to and after 2, 4 and 6 CT-P13 infusions. Results 178 patients were included. Non-inferiority was established for QoL (ratio 97.95% (95% CI 95.93-100.01) and efficacy (difference –0.02 (95% CI -0.68-0.64)). Five patients reported 6 non-related, serious adverse events. Conclusion Switching from reference infliximab to CT-P13 did not affect the QoL or disease activity and was well tolerated.
