BACKGROUND: Perianal fistulas represent a severe complication of Crohn's disease (CD), leading to significant morbidity and a decline in patients' quality of life. Adalimumab, a tumor necrosis factor (TNF) inhibitor, has been widely used for managing CD-related fistulas. However, with the introduction of adalimumab biosimilars, their comparative efficacy in fistula closure remains unclear. This systematic review and meta-analysis assessed the effectiveness and safety of adalimumab biosimilars in achieving complete fistula closure in moderate to severe CD.
OBJECTIVE: To evaluate the efficacy of adalimumab biosimilars in achieving complete fistula closure in patients with moderate to severe Crohn's disease, compared to placebo or standard therapies.
METHODS: A systematic review and meta-analysis were conducted following PRISMA guidelines. Studies published between 2007 and 2024 were retrieved from PubMed, Web of Science, Embase, Google Scholar, and the Cochrane Library. The included studies consisted of randomized controlled trials (RCTs), non-RCTs, case-control studies, and cohort studies that evaluated the efficacy of adalimumab biosimilars in fistula closure. Data extraction and quality assessment were independently performed using the MINORS evaluation tool. Heterogeneity was assessed using Q and I² statistics, and sensitivity analyses were conducted to explore potential sources of heterogeneity. Funnel plots were used to assess publication bias.
RESULTS: Ten studies met the inclusion criteria. The analysis demonstrated that adalimumab biosimilars significantly improved the complete fistula closure rate compared to placebo or conventional treatments. The pooled results indicated a moderate to high efficacy, with a statistically significant improvement in clinical remission rates (P < 0.05). Safety analysis revealed that adverse events were comparable between biosimilars and the original adalimumab, with no significant increase in serious adverse reactions. Sensitivity analysis confirmed the robustness of the findings, and publication bias assessment did not indicate significant bias.
CONCLUSIONS: This meta-analysis supports the efficacy and safety of adalimumab biosimilars in managing perianal fistulas in moderate to severe CD. The findings suggest that adalimumab biosimilars are effective and safe in managing perianal fistulas in Crohn's disease, but further direct comparative studies with originator adalimumab are needed to establish equivalence. Further large-scale RCTs are recommended to confirm these results and establish long-term safety data.
