Brief Summary
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.

Outcome Measures
Primary Outcomes (1)
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.
Evaluation of the distribution of modified Rutgeerts score grouped in 4 categories (i0: No lesions in the neoterminal ileum, i1: ≤ 5 ulcerations in the neoterminal ileum - i2a: Isolated anastomotic ulceration, i2b: \>5 ulcerations in the neoterminal ileum, i3: Diffuse ileitis - i4: Diffuse ileitis with deep ulcerations and/or stenosis) at Week 24/EOT, evaluated by endoscopy with video capture, and assessed by BICR.
From enrollment to the end of treatment at 24 weeks
Study Arms (2)

PLACEBO COMPARATORPlacebo administered with or without SoC treatment orally, once a day during 24 weeks
Interventions
Randomisation will be stratified on post-surgical treatment (none vs anti-TNF), and on smoking status (non-smoker vs smoker).
Eligibility Criteria
You may qualify if:
- 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 undergone an ileocecal resection or iterative ileo-colonic resection, as per institutional SoC, between 5 days to 5 weeks before randomization.
- Is scheduled, in SoC context, to receive no treatment for CD or anti-TNF agents in the 6 months after surgery
You may not qualify if:
- Has a not recovered adequately from any toxicity and/or complications from the surgery before the first dose of study intervention

- 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.
