About this study

  • Purpose: The investigators aimed to investigate the safety and efficacy in the treatment of fecal incontinence by injection of ALLO-ASC into the anal sphincter.
  • Method
  1. Safety test of allogenic ASCs injection
  2. Efficacy test of allogenic ASCs injection
Read the detailed description
  • Background: Fecal incontinence is a distressing condition with recurrent uncontrolled passage of fecal material. Although fecal incontinence is developed by multifactorial causes, treatments were limited in medical or surgical methods. According to the recent studies of stem cell regeneration, it is reported that human adipose-derived stem cells have plentiful capacity in muscle regeneration, which had the efficacy to treat Crohn's fistulas. Therefore, the investigators hypothesized that the capability of muscle regeneration of allogenic-adipose-derived mesenchymal stem cells (ALLO-ASC) can be used to treat degenerated anal sphincter, which leads to fecal incontinence.
  • Purpose:The investigators aimed to investigate the safety and efficacy in the treatment of fecal incontinence by injection of ALLO-ASC into the anal sphincter.
  • Method
  1. Safety test of allogenic ASCs injection In the first year, the investigators will investigate the safety of ALLO-ASC injection by a dose escalation study. Patients are sequentially enrolled into three groups, which are composed of three patients each. They are treated with an injection of ALLO-ASC to the anal sphincter for 3x107 cells/ml (group 1), 6x107 cells/ml (group 2), 9x107 cells/ml (group 3), respectively. After receiving the ALLO-ASC injection, patients will receive a physical examination, a serologic and immunologic response test (CD4/CD8) with an assessment of the Wexner score, patient satisfaction survey, WHO toxicity scale, adverse events, anorectal manometry and endorectal ultrasound at 1, 4, 8 weeks, 4, 6, 9, and 12 months in the outpatient clinic. The response of ALLO-ASC injection is assessed at 8 weeks after an injection and the most effective dose is determined among the groups.
  2. Efficacy test of allogenic ASCs injection In the second year, the investigators will assess the efficacy of the ALLO-ASC injection comparing the ALLO-ASC injection group and the placebo group (0.9% normal saline injection) by a randomized, open-label, single-blind design. Each group is composed of six patients. Both the clinical assessment and follow-up period are identical with the first-year protocol.

What is being measured

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

  1. Clinically measured abnormality of laboratory tests and adverse events

    The investigators will assess the safety of allogenic-adipose-derived mesenchymal stem cell (ALLO-ASC) injection to the anal sphincter among the three experimental groups (group 1: 3x107 cells/ml; group 2: 6x107 cells/ml; group 3: 9x107 cells/ml)).

    Measured: one year (12 months)

Secondary outcomes (1)
  1. Satisfaction as measured by Wexner Score

    Improvement of Wexner Score at 12 months compared to baseline per each group. (The investigators will assess the efficacy of the ALLO-ASC injection comparing the ALLO-ASC injection group and the placebo group (0.9% normal saline injection) by a randomized, open-label, single-blind design.)

    Measured: one year (12 months)

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing ALLO-ASC injection in people with Fecal Incontinence, run by Yonsei University at 1 site in South Korea.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 6 inclusion and 17 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 13 Aug 2018. 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 South Korea. 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. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

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?

Clinically measured abnormality of laboratory tests and adverse events (time frame: one year (12 months)). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT02384499, which also lists 7 linked publications.

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 13 Aug 2018.
