Background
Several effective advanced therapies have been approved for the treatment of Crohn’s disease (CD) in the past two decades. Many have used synthesis techniques to study this area, but these rarely consider both advanced and immunomodulator therapy together in the same analysis. Network meta-analysis enables the direct and indirect comparison of these different therapeutic agents, aiding in determining their relative positioning within the treatment algorithm.
Methods
We searched MEDLINE, Embase, and Cochrane Central Register of Controlled Trials between inception and October 2023 for randomised controlled trials (RCTs). The outcomes included were clinical remission and response, adverse events (AE), withdrawal due to AE, total and serious AE. We performed random-effects meta-analysis and network meta-analysis (frequentist approach), and estimated relative risk (RRs), 95%CI values. We used GRADE to ascertain certainty of evidence.
Results
A total of 83 RCTs comprising 19214 patients were eligible. A total of 28 interventions were included in the analysis. Combination of anti-tumor necrosis factor (TNF) and immunomodulators, anti-TNF monotherapy (adalimumab [ADA], infliximab [IFX], BI695501), IL-23 antagonists (ustekinumab [UST], guselkumab, risankizumab [RIS], mirikizumab), anti-integrins (vedolizumab, natalizumab) and upadacitinib were effective in inducing clinical remission compared to placebo (Figure 1). There was moderate certainty of evidence for combination of ADA and azathioprine (AZA) (RR 3.1, 95%CI [2.0-4.8]; risk difference [RD]: 40.1%), IFX+AZA (RR 2.5, 95%CI [1.7-3.8]; RD: 28.9%), ADA (RR 2.5, 95%CI [1.8-3.5]; RD:28.5%), and UST (RR 2.0 95%CI, [1.6-2.5]; RD: 19.2%) in induction of clinical remission compared to placebo. For induction of clinical response, there was moderate certainty of evidence for IFX+AZA (RR 2.8, 95%CI [1.6-4.8]), ADA (RR 2.5, 95%CI [1.7-3.9]), IFX (RR 2.8, 95%CI [1.6-4.8]), RIS (RR 1.9, 95%CI [1.3-2.6]). On analysis of serious adverse events all therapies were of no difference to placebo (very low certainty). On sensitivity analysis, the impact of concomitant immunomodulator use and the biological naivety of patients had little effect on these results.
Conclusion
On network meta-analysis, combination of anti-TNFs and immunomodulators followed by anti-TNF monotherapy had large effect size with moderate certainty for the induction of clinical remission. More novel therapies appear to have examples of simila |
