About this study
From January 2018 to May 2025, diagnosed CD patients and gender- and age-matched normal controls were collected from Department of Gastroenterology, the Second Affiliated Hospital of Wenzhou Medical University. Our study aimed to explore the associations of interleukin 12 receptor subunit beta 1 (IL-12RB1) gene polymorphisms with the risk and clinicopathological characteristics of Crohn's disease (CD), and to analyze the effects of IL-12RB1 gene variations on the clinical response of ustekinumab (UST) treatment in CD patients at week 8.
Read the detailed description
From January 2018 to May 2025, diagnosed CD patients and gender- and age-matched normal controls were collected from Department of Gastroenterology, the Second Affiliated Hospital of Wenzhou Medical University. Genotypes of IL-12RB1 were examined by multiplex polymerase chain reaction-ligase detection reaction technique. Unconditional logistic regression analysis was employed to analyze the distribution differences of IL-12RB1 gene polymorphisms between CD group and normal control group, as well as their influences on the clinicopathological characteristics and 8-week clinical response to UST treatment of CD patients.

Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 10 Jul 2025. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in China. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Genotypes of IL-12RB1 (time frame: Baseline). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 10 Jul 2025.
