Optimal Care With Guselkumab in Crohn's Disease / OPTIM Study A Prospective Open Label Interventional, Multicenter Study (OPTIM)
Optimal Care With Guselkumab In Crohn's Disease
Crohn's disease (CD) is a chronic and destructive inflammatory disease of the gastrointestinal tract characterized by phases of relapse and remission. Tumor necrosis factor (TNF) antagonists, anti-integrins and anti-interleukin (IL) 12/23 are the main therapeutic agents to obtain deep remission and prevent disability. Despite the significant advances these biologics represent in treating inflammatory bowel disease (IBD), many patients experience suboptimal responses, including primary non-response or a loss of effectiveness over time, often leading to treatment discontinuation. For all these medications, a dose-response relationship has been demonstrated and an increase in dose or dosing frequency is recommended. Dose escalation is now an essential therapeutic approach necessary in 30 to 50% of CD patients treated with biologics. This strategy, supported by international guidelines, allows for long-term efficacy to be maintained without compromising safety.
Guselkumab (GUS) is a monoclonal antibody targeting the p19 subunit of IL-23. In a recent phase III trial (GALAXI), GUS demonstrated superiority of both subcutaneous (SC) maintenance doses (200 mg every 4 weeks [q4w] and 100 mg every 8 weeks [q8w]) compared to placebo and ustekinumab. In the GALAXI phase III program, at least 30% of patients did not achieve clinical response after a 12-week intravenous induction, and almost 20% experienced a loss of response by week 44. In these patients, the benefit of an intensified dose of GUS (200 mg q4w) maintenance remains to be determined to guide clinicians in optimizing its use in clinical practice. The investigator aimed to evaluate the one-year effectiveness of GUS in CD in real-world settings and under optimal conditions allowing dose intensification.

Szczegółowy opis
Interventionnel, open multicenter study, the objectives are:
Primary Objective To evaluate the one-year effectiveness of GUS in CD in real-world setting.
Secondary Objectives
- To evaluate the effectiveness of GUS intensification from 100 mg q8w to 200 mg q4w in patients with loss of response,
- To evaluate the effectiveness of an intensified GUS 200 mg q4w maintenance therapy in patients who are primary non-responders to GUS SC induction at 12 weeks;
- To assess the factors associated with GUS intensification effectiveness.

Eksperymentalny: Guselkumab Dose Optimization Strategy
Participants with active Crohn disease receive guselkumab treatment as part of a treat-to-target strategy.
During maintenance therapy, dose optimization may be performed according to clinical response criteria defined in the protocol.
|
Guselkumab is a human monoclonal antibody targeting IL-23.
In this study, patients receive guselkumab as part of a treat-to-target strategy.
At week 12 (W12), patients are managed according to disease response: those with adequate response continue standard maintenance dosing, while non-responders are escalated to an intensified treatment regimen with adjusted dosing frequency.
