  • Failure to respond to existing conventional therapy, or to primary or secondary treatment with TNF alpha monoclonal antibody, vedolizumab or ustekinumabd.
  • Current Crohn's disease with a Crohn's Disease Activity Index (CDAI) score ≥ 220 and ≤ 450.
  • Evidence of active inflammation and ulceration confirmed by endoscopy during screening.
  • Subjects must be free of active, latent, or undertreated Mycobacterium tuberculosis infection.
Show all 10Show fewer
  • All women of childbearing potential and all men must be willing to use at least one highly effective method of contraception at the time of signing the consent form and throughout the study period until 1 month after the last dose of study drug.
  • Subjects who are willing and able to undergo treatment and follow-up, laboratory tests, and other study procedures as planned.
  • Subjects who are able to sign (and date) an informed consent form indicating that the subject has been informed of all relevant parts of the study
  • Subjects receiving non-disabling combination therapy for any reason must maintain a stable treatment regimen, defined as no stem cell therapy given or no dose change within 7 days or 5 half-lives (whichever is longer) prior to the initial stem cell injection.

Who cannot join

  • Presence of a complication of Crohn's disease, such as short bowel syndrome or any other manifestation that might be expected to require surgery, that prevents the use of CDAI to assess treatment response, or that might confound the assessment of the efficacy of MSC therapy.
  • Current abscess or suspected abscess. If the abscess has drained and been adequately treated 3 weeks prior to baseline (skin and perianal abscesses) and 8 weeks prior to baseline (intra-abdominal abscesses) then no exclusion is necessary. The prerequisite is that no further surgical treatment is anticipated. Subjects may be enrolled in the study if they have an active fistula that is not expected to require surgery and is confirmed to be abscess-free.
  • Subjects with evidence of pathogenic intestinal infection. Subjects with Clostridium difficile or other intestinal infections within 30 days of endoscopic screening, or subjects who screen positive for C. difficile toxin assay or other pathogens.

  • Prior history of alcohol or drug abuse and less than 6 months of abstinence prior to baseline.
  • Subjects with clinically relevant abnormalities confirmed by 12-lead ECG during the screening period that would affect their safety if enrolled in this study or affect the interpretation of the study results.

About this study

Official title: A Single-arm, Open-label Clinical Study of Human Umbilical Cord Mesenchymal Stem Cells in the Treatment of Refractory Moderate to Severe Crohn's Disease

This is a prospective, single-arm, open-ended study to evaluate the efficacy and safety of human umbilical cord MSCs in the treatment of refractory moderate-to-severe Crohn's disease. The study protocol is either MSC injection into the patient's diseased intestinal mucosa or intravenous MSC injection + MSC injection into the patient's diseased intestinal mucosa. Follow-up time points were pre-treatment (week 0), week 4, week 8, week 12, and week 24 post-treatment, and the primary evaluation at follow-up was the number of subjects with clinical and endoscopic response or remission.

Read the detailed description

This is a prospective, single-arm, open study to evaluate the efficacy and safety of human umbilical cord MSCs in the treatment of refractory moderate-to-severe Crohn's disease. The study will be conducted as follows: a total of 40 patients will be recruited and will receive either MSC injection into the diseased intestinal mucosa or intravenous MSC injection + MSC injection into the diseased intestinal mucosa. The proportion of patients with clinical and endoscopic response or remission will be used as the primary evaluation for follow-up. The Crohn's disease activity index (CDAI) was used to assess the severity of CD disease, with CDAI <150 considered to be in clinical remission; a decrease in CDAI ≥70 was considered to be clinically effective, also referred to as clinical response. Endoscopic response was defined as at least 50% improvement in the simplified endoscopic score for Crohn's disease (SES-CD) from baseline, and endoscopic remission was defined as a SES-CD score ≤2.

MSCs local treatment group/combined treatment groupExperimentalIn the local treatment group, 60 million umbilical cord MSCs were injected into the diseased intestinal mucosa on the first day. In the combined treatment group, 60 million umbilical cord MSCs were injected into the diseased intestinal mucosa on the first day; on the second day, 1 million cells/kg of body weight were administered intravenously.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Crohn's disease activity index score

    The Crohn's Disease Activity Index (CDAI) was used to assess the severity of CD disease, and a CDAI <150 was considered clinically remitting; a decrease in CDAI ≥70 was considered clinically effective, also known as clinical response.

    Measured: Changes from baseline to week 4, week 8, week 12 and week 24 after stem cell treatment.

  2. simplified endoscopic score for Crohn's disease

    Endoscopic response was defined as at least 50% improvement in the simplified endoscopic score for Crohn's disease (SES-CD) from baseline, and endoscopic remission was defined as a SES-CD score ≤2.

    Measured: Changes from baseline to week 4, week 8, week 12 and week 24 after stem cell treatment.

Secondary outcomes (5)
  1. Inflammatory Bowel Disease Questionnaire

    The Inflammatory Bowel Disease Questionnaire (IBDQ) is a widely used questionnaire for Health-related quality of life assessment in patients with inflammatory bowel diseases (IBDs).

    Measured: Changes from baseline to week 4, week 8, week 12 and week 24 after stem cell treatment.

  2. Albumin

    Albumin is an important component of the blood, and patients with severe Crohn's disease can present with clinical signs of hypoproteinemia.

    Measured: Changes from baseline to week 4, week 8, week 12 and week 24 after stem cell treatment.

  3. Hemoglobin

    Hemoglobin is an important component of the blood, and patients with severe Crohn's disease can present with clinical signs of anemia.

    Measured: Changes from baseline to week 4, week 8, week 12 and week 24 after stem cell treatment.

  4. Fecal calprotectin

    Fecal calprotectin (FC) is a non-invasive marker of gastrointestinal inflammation with advocated diagnostic precision in distinguishing inflammatory bowel disease (IBD) from non-IBD diagnoses.

    Measured: Changes from baseline to week 4, week 8, week 12 and week 24 after stem cell treatment.

  5. body mass index (BMI)

    Weight and height will be combined to report BMI in kg/m^2

    Measured: Changes from baseline to week 4, week 8, week 12 and week 24 after stem cell treatment.
