Selinger CP, Rosiou K, Lenti MV. Biological therapy for inflammatory bowel disease: cyclical rather than lifelong treatment? BMJ Open Gastroenterol 2024; 11:e001225. [PMID: 38341192 PMCID: PMC10870786 DOI: 10.1136/bmjgast-2023-001225] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/29/2023] [Accepted: 01/04/2024] [Indexed: 02/12/2024] Open
Abstract
Inflammatory bowel disease (IBD) treatment was revolutionised with the arrival of biological therapy two decades ago. There are now multiple biologics and increasingly novel small molecules licensed for the treatment of IBD. Treatment guidelines highlight the need for effective control of inflammation and early escalation to advanced therapies to avoid long-term complications. Consequently, a large proportion of patients with IBD receive advanced therapies for a long time. Despite their beneficial risk-benefit profile, these treatments are not without risk of side effects, are costly to healthcare providers and pose a burden to the patient. It is, therefore, paramount to examine in which circumstances a temporary cessation of therapy can be attempted without undue clinical risk. Some patients may benefit from cyclical rather than continuous treatment. This review examines the risk of relapse after discontinuation of advanced therapies, how to identify patients at the lowest risk of relapse and the chance of recapturing response when flaring after discontinuation.

Katibian DJ, Solitano V, Polk DB, Nguyen T, Ma C, Syal G, Kobayashi T, Hibi T, Buhl S, Ainsworth MA, Jairath V, Singh S. Withdrawal of Immunomodulators or TNF Antagonists in Patients With Inflammatory Bowel Diseases in Remission on Combination Therapy: A Systematic Review and Meta-analysis. Clin Gastroenterol Hepatol 2024; 22:22-33.e6. [PMID: 37716619 DOI: 10.1016/j.cgh.2023.08.039] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/23/2023] [Revised: 07/25/2023] [Accepted: 08/19/2023] [Indexed: 09/18/2023]
Abstract
BACKGROUND & AIMS Withdrawal of immunomodulators (IMMs) or tumor necrosis factor (TNF) antagonists in patients with inflammatory bowel diseases (IBDs) in remission on combination therapy is attractive. We evaluated the efficacy and safety of (1) IMM, or (2) TNF antagonist withdrawal in patients with IBD in sustained remission on combination therapy. METHODS Through a systematic review till March 31, 2023, we identified randomized controlled trials (RCTs) that compared the efficacy and safety of IMM or TNF antagonist withdrawal vs continued combination therapy, in patients with IBD in sustained corticosteroid-free clinical remission for >6 months on combination therapy. Primary outcome was risk of relapse and serious adverse events at 12 months. We conducted meta-analysis to calculate relative risk (RR) and 95% confidence interval (CI) and used Grading of Recommendations Assessment, Development and Evaluation (GRADE) to appraise certainty of evidence. RESULTS We identified 8 RCTs with 733 patients (77% with Crohn's disease, 91% on infliximab-based combination therapy). On meta-analysis of 5 RCTs, there was no difference in the risk of relapse between patients with IMM withdrawal (continued TNF antagonist monotherapy) vs continued combination therapy (16.8% vs 14.9%; RR, 1.15; 95% CI, 0.75-1.76) without heterogeneity (low certainty of evidence). TNF antagonist withdrawal (continued IMM monotherapy) was associated with 2.4-times higher risk of relapse compared with continuing combination therapy (31.5% vs 11.2%; RR, 2.35; 95% CI, 1.38-4.01), with minimal heterogeneity (low certainty of evidence). There was no difference in the risk of serious adverse events with IMM or TNF antagonist withdrawal vs continued combination therapy. CONCLUSIONS In patients with IBD in sustained corticosteroid-free clinical remission for >6 months on combination therapy, de-escalation with TNF antagonist withdrawal, but not IMM withdrawal, was associated with an increased risk of relapse.

Safety and Effectiveness of SB2 (Infliximab Biosimilar) in Adult Patients with Immune-Mediated Inflammatory Diseases: A Post-Marketing Surveillance in Korea. Adv Ther 2023; 40:1047-1061. [PMID: 36624354 PMCID: PMC9989004 DOI: 10.1007/s12325-022-02404-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/13/2022] [Accepted: 12/07/2022] [Indexed: 01/11/2023]
Abstract
INTRODUCTION SB2 is a biosimilar of infliximab (IFX), which is approved for rheumatoid arthritis (RA), ankylosing spondylitis (AS), adult and pediatric Crohn's disease (CD), adult and pediatric ulcerative colitis (UC), psoriatic arthritis (PsA), and plaque psoriasis (PsO). The drug approval process in Korea includes post-marketing surveillance (PMS) studies to re-examine the safety and effectiveness of approved new medications. METHODS This was a prospective, multi-center, open-label, observational, phase 4 PMS study of IFX-naïve patients or patients switched from reference IFX or another IFX-biosimilar to SB2 in all approved indications. The primary endpoint was to evaluate the safety of SB2 reported as adverse events (AEs) and adverse drug reactions (ADRs). The secondary endpoint was to evaluate the effectiveness measured as investigators' overall effectiveness assessment, categorized as improved, stable, or worsened. Furthermore, disease-specific activity scores were collected for each indication [28-joint Modified Disease Activity Score (DAS28) for RA, Korean Bath Ankylosing Spondylitis Disease Activity Index (KBASDAI), Crohn's Disease Activity Index (CDAI), and Full Mayo Score for UC]. RESULTS In the safety and effectiveness analysis, 180 and 128 patients were included, respectively. Most patients (83.9%) were IFX-naïve patients and 16.1% were switched patients. RA (48.9%) and AS (31.1%) were the most frequent indications. Overall, 23 (12.8%) patients reported AEs and 14 (7.8%) patients reported ADRs. Serious adverse events (SAEs) were reported by 3 (1.7%) patients. As per investigators' overall effectiveness assessments, SB2 was effective in 94.6% (105/111) of IFX-naïve patients and 82.4% (14/17) of switched patients. In IFX-naïve patients, disease activity scores decreased significantly from baseline to week 30 (week 24 for AS); mean (SD) changes of disease scores for each indication were DAS28 - 1.9 (0.79) for RA, KBASDAI - 3.8 (1.68) for AS, CDAI - 200.4 (112.47) for CD, and Full Mayo Score - 6.6 (2.92) for UC. The persistence rate of SB2 treatments was 88.3% with median treatment duration of 30.1 weeks. CONCLUSION This PMS study of the IFX-biosimilar SB2 in Korea confirmed the safety and effectiveness of SB2 in major indications.
