ECCO Topical Review on Biological Treatment Cycles in Crohn's Disease.

There are now a growing number of licensed biological therapies for patients with Crohn's disease. However, there can be significant costs associated with long-term maintenance treatment, as well as some concerns about potential side effects. As a result, there has been increasing interest in elective biological treatment discontinuation in selected patients, after a sustained period of remission. Following discontinuation, in cases of relapse, evidence to date has suggested that remission may often be regained by retreatment with the same biological agent. Therefore, a concept has emerged where cycles of biological therapy might be used. If this treatment strategy were to be applied in a subgroup of patients at low-risk of relapse, cycling might allow a substantial number of patients to have a lower, overall therapeutic burden - ensuring decreased exposure to biological therapy but still enabling appropriate disease control. Currently, there remains uncertainty about the benefit-risk balance for using cycles of biological treatment for patients with Crohn's disease. Accordingly, an expert panel was convened by the European Crohn's and Colitis Organisation (ECCO) to review the published literature and agree a series of consensus practice points. The panel aimed to provide evidence-based guidance on multiple aspects of biological treatment discontinuation and cycling, including the risk of relapse after elective treatment discontinuation, predictors of likely relapse or remission, safety, patient preferences and pharmacoeconomic aspects. Crucially, discussions about biological treatment discontinuation and cycling should be individualised, to enable shared decision-making by patients with their clinicians.
