Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  • The subject or guardian must provide voluntary ;
  • Diagnosis based on the "Chinese Guidelines for the Diagnosis and Treatment of Ulcerative Colitis (2023, Xi'an)": Patients diagnosed with UC (based on comprehensive evaluation including clinical, imaging, pathological, and endoscopic assessments), with a follow-up period of more than 3 months;
  • Moderate to severe active ulcerative colitis: Patients meeting the criteria of a clinical modified Mayo score of 6-12 points and an endoscopic Mayo score (ES) ≥ 2 points (within 10 days prior to baseline);
  • Previous treatments with all domestically approved medications for UC, including conventional drugs, biologics, and small molecule drugs, have failed;
  • Hematological, liver and kidney function, cardiopulmonary function, and coagulation function meet specific criteria.

Exclusion criteria

Exclusion Criteria:

  • Women who are pregnant or lactating;
  • Any condition that, in the judgment of the Investigator, could increase the subject's risk or compromise the interpretation of the trial results;
  • Diagnosed with CD (Crohn's Disease) or indeterminate colitis (IBD-unclassified), or other types of colitis or enteritis that may confound efficacy assessment;
  • Currently diagnosed with fulminant colitis and/or toxic megacolon;
  • UC limited to the rectum;
  • Currently or likely to require colostomy or ileostomy;
  • Has previously undergone total proctocolectomy or partial colectomy.
  • Patients who test positive for surface antigen (HBsAg) should be excluded; if HBsAg is negative but hepatitis B core antibody (HBcAb) is positive, and peripheral blood HBV DNA is above the detection limit, they should be excluded; patients who test positive for virus (HCV) antibodies and HCV RNA should be excluded; patients who test positive for (HIV) antibodies; patients who test positive for cytomegalovirus (CMV) DNA; patients who test positive for Epstein-Barr virus (EBV) DNA; patients who test positive for both treponemal-specific antibodies and non-specific antibodies for syphilis should be excluded.
  • Any uncontrolled active infection present at the time of signing the ICF.
  • Subjects who have had severe, opportunistic, or chronic/recurrent extra-intestinal infections within 2 months prior to screening; evidence of active/infectious herpes zoster infection within 8 weeks prior to screening; active tuberculosis or latent tuberculosis infection present at screening.
Terms in these criteria, in plain language(5)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Immunosuppression

A weakened immune system. It can come from an illness, such as HIV or some blood cancers, or from medicines that turn the immune system down, for example after an organ transplant or for an autoimmune disease; steroids at higher doses count.

Read whether the line is about a condition or about medicines, and which medicines and doses it means.

Hepatitis B tests

Hepatitis B is a virus that infects the liver. These are separate tests: HBsAg positive usually means a current infection (a recent vaccination can briefly cause it too); total anti-HBc (HBcAb) positive means an infection now or in the past; HBV DNA measures how much virus is in the blood.

Some studies accept a past infection if HBV DNA is undetectable, sometimes with antiviral medicine during the study. Check what this study allows.

Hepatitis C tests

Hepatitis C is a virus that infects the liver. An HCV antibody test can stay positive after an infection has cleared (and is occasionally positive without one); an HCV RNA test shows whether the virus is there now.

After treatment, hepatitis C counts as cured when HCV RNA is still undetectable 12 weeks or more after the treatment ended. Studies often accept people cured this way.

HIV

The human immunodeficiency virus, which weakens the immune system.

Many studies now accept people whose HIV is controlled on treatment, judged by the viral load and the CD4 count. Check the limits this study sets.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Feb 27, 2026, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
