Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

MAINTAIN-POP is a Phase 2, randomised, double-blind, placebo-controlled, multicenter study of the impact of oral administration of EXL01 in the prevention of post-operative endoscopic recurrence of Crohn's disease after surgery.

Approximately 80 eligible patients will be randomized 1:1 to receive oral EXL01 or placebo with or without SoC treatment (based on investigator decision) for up to 24 weeks or until a study or treatment discontinuation criterion is met. Randomisation will be stratified on post-surgical treatment (none vs anti-TNF), and on smoking status (non-smoker vs smoker).

The primary objective is to compare the distribution of endoscopic modified Rutgeerts scores, as centrally assessed, at 6 months post-surgery in patients with CD treated with EXL01 to patients treated with placebo. Endoscopic recurrence will be assessed using the endoscopic score assessed by central reading at Week 24 after surgery. All participants will be followed for safety until 4 weeks after end of treatment.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

MAINTAIN-POP is a Phase 2, randomised, double-blind, placebo-controlled, multicenter study of the impact of oral administration of EXL01 in the prevention of post-operative endoscopic recurrence of Crohn's disease after surgery.

After surgery for Crohn's disease, as per institutional Standard of Care (SoC), approximately 80 eligible patients will be randomized 1:1 to receive oral EXL01 or placebo with or without SoC treatment (based on investigator decision) for up to 24 weeks or until a study or treatment discontinuation criterion is met. Randomisation will be stratified on post-surgical treatment (none vs anti-TNF), and on smoking status (non-smoker vs smoker).

The primary objective is to compare the distribution of endoscopic modified Rutgeerts scores, as centrally assessed, at 6 months post-surgery in patients with CD treated with EXL01 to patients treated with placebo.. All patients will be monitored continuously for safety while on the study treatment. Endoscopic recurrence will be assessed using the endoscopic score assessed by central reading at Week 24 after surgery. Faecal and blood samples for biomarker assessments will be obtained at Weeks 0, 4, 12, and 24. Patients who experience disease flare before Week 24 will discontinue the study treatment (EXL01 or placebo) and undergo an early discontinuation (ED) visit. All participants will be followed for safety until 4 weeks after end of treatment.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

* Is male or female aged ≥18 years at the time of providing documented informed consent.
* Has a diagnosis of CD with ileal involvement (ileal only or ileocolonic; L1 or L3 in Montreal classification) for at least 3 months prior to Screening.

* Has had more than 2 past small bowel resections or cumulated intestinal resection superior to 50 cm
* Has a contraindication to endoscopy or anaesthesia.
* Is receiving antibiotics at time of randomization or is likely to require antibiotic treatment within 6 weeks of the first dose of EXL01 or placebo.
* Has a history of hypersensitivity to EXL01 and/or any excipients, which are listed in the Investigator Brochure (IB), and/or to soybean or soy-containing products.
* Has a not recovered adequately from any toxicity and/or complications from the surgery before the first dose of study intervention
