An Observational, Multicenter Study to Evaluate the Effectiveness of Guselkumab for the Treatment of Participants With Crohn's Disease After Surgical Resection (POST-CD)

April 7, 2026 updated by: Xiaolei Wang, Shanghai 10th People's Hospital
The goal of this single arm ,non-interventional, prospective, descriptive study is to evaluate the efficacy of guselkumab treatment in preventing endoscopic recurrence of Crohn's Disease in adult participants who have a documented diagnosis of moderate to severe CD and have undergone an ileocolonic surgical resection. The primary endpoint is Endoscopic recurrence rate at week24.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

This is an open-labeled, single arm, non-interventional, prospective, descriptive study, planned to include postoperative CD patients. After ileocolonic surgical resection, the patients who are treated with GUS will be enrolled in this study. The period is 48 weeks. The primary endpoint is Endoscopic recurrence （modified Rutgeerts score ≥ i2b）at Wk 24. IA is planned to be conducted when 30% of the enrolled patients have finished 24wk follow up. The Secondary endpoint are Clinical remission without recurrence（CDAI < 150）at Wk24/Wk48;Endoscopic recurrence at Wk48 (modified Rutgeerts score ≥ i2b);Endoscopic remission（SES-CD≤3）at Wk24/48;Safety profile. Exploratory endpoint includes histologic score (Geboes scale/RHI/GHAS) at Wk24/48 ileocolonoscopy; time to endoscopic recurrence; time to recurrence of symptoms; endoscopic recurrence rate at Wk24/48(POCER)

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

Sampling Method

Non-Probability Sample

Study Population

The target population is male or female participants (minimum age 18) with a diagnosis of CD who have had a qualifying surgery (eg, ileocolonic resection) at most 3months before enrolled. Participants will be excluded if they have a short segment of bowel affected (ie,less than 10 cm) for fibrostenotic disease and they had their first surgery more than 10 years after diagnosis of CD. There is no requirement that participants have failed prior biologics.

Description

Inclusion Criteria:

  • Patients≥ 18，
  • Have a documented diagnosis of moderate to severe CD
  • Have undergone an ileocolonic surgical resection

Exclusion Criteria:

  • Has complications of CD, such as short bowel syndrome Currently has or is suspected to have an abscess
  • Active infection
  • Currently has a malignancy or has a history of malignancy within 5 years

Gulselkumab after surgery
The target population is male or female participants (minimum age 18) with a diagnosis of CD who have had a qualifying surgery (eg, ileocolonic resection) at most 3months before enrolled. Participants will be excluded if they have a short segment of bowel affected (ie,less than 10 cm) for fibrostenotic disease and they had their first surgery more than 10 years after diagnosis of CD. There is no requirement that participants have failed prior biologics.
Drug: Guselkumab
Guselkumab is an IL23 p19 subunit antagonist that binds to IL-23 with high affinity and potency and also binds to the CD64 receptor (high affinity Fcγ receptor 1) on the surface of human inflammatory monocytes, which enables it to neutralize IL-23 at its predominant source of production, potentially enriching the presence of guselkumab in the inflamed tissue microenvironment.GALAXI and GRAVITI studies have demonstrated that Guselkumab treatment was both safe and effective for induction and maintenance of remission is patients with moderate to severely active CD. No study is about the efficacy of IL-23is in POCD

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
