Anti-TNF agents for the treatment of Crohn's disease

A study in the latest publication of Alimentary Pharmacology & Therapeutics compares the efficacy of anti-TNF therapies in Crohn's disease.

Anti-tumor necrosis factor-alpha agents (anti-TNF) are effective therapies for the treatment of Crohn's disease, but their comparative efficacy is unknown.

Dr Waljee and colleagues from Michigan, USA performed a network meta-analysis comparing the efficacy of anti-TNF therapies in Crohn's disease.

After screening 506 studies, reviewers extracted information on 10 studies.

Traditional meta-analysis was used to compare each anti-TNF agent to placebo.
 
Bayesian network meta-analysis was performed to compare the effects of anti-TNF agents to placebo.

In addition, sample sizes for comparative efficacy trials were calculated.

Adalimumab was superior to certolizumab pegol for induction of remission
Alimentary Pharmacology & Therapeutics

Compared to placebo, TMA revealed that anti-TNF agents result in a higher likelihood of induction of remission and response as well as maintenance of remission and response.

The research team found nonsignificant trends between infliximab and adalimumab or certolizumab pegol.
 
Among subcutaneous therapies, the team demonstrated superiority of adalimumab to certolizumab pegol for induction of remission.

Dr Waljee and team comment, "All anti-TNF agents are effective for induction and maintenance of response and remission in the treatment of Crohn's disease."

"Although adalimumab is superior to certolizumab pegol for induction of remission, there is no evidence of clinical superiority among anti-TNF agents."

"Head-to-head trials among the anti-TNF agents are impractical in terms of size and cost."
