About this study

Official title: Multicenter Phase I/IIa Study to Assess the Safety and Efficacy of Expanded Allogenic Adipose-derived Stem Cells (eASCs) (Cx601), for Treatment of Complex Perianal Fistulas in Perianal Crohn's Disease.

The purpose of this study is to asses the safety and efficacy of adipose-derived adult stem cells from healthy donnors for treatment of complex perianal fistulas in Crohn's disease.

Read the detailed description

Crohn´s disease (CD) is a severe disorder with significant morbidity and major impact on life. CD can affect any part of the digestive system and symptoms of this chronic illness include abdominal pain, bloating, nausea, vomiting and diarrhea. CD also causes bowel wall ulcers, strictures (narrowing of a hollow structure due to scar tissue and swelling), and fistulas (abnormal passages from the intestines to another organ or the skin).

There is an unmet need for effective medical therapy in CD patients with perianal fistulas, not responding to the conventional strategies, including biological therapies. The current study is designed to assess the safety and efficacy of adipose tissue derived mesenchymal stem cells from healthy donors for the treatment of perianal fistulas in patients presenting CD.

Primary objective: To assess the safety (incidence of treatment emergent adverse-events) of eASCs.

Study design: Multicenter, pilot study, assessing safety and with evaluation of the efficacy by two Gastroenterologists/Surgeons and an independent external radiologist. Subjects will receive a cell suspension of allogenic adipose-derived stem cells, eASCs (20 million cells) in the fistula.

In case of incomplete fistula closure of the treated fistula at week 12, subjects will receive a second dose of eASCs (40 million cells). Subjects will be followed until week 24, following the initial administration of cells.

Subjects may be treated with standard care during the entire study period, according to the investigators discretion, excluding infliximab or any other anti-TNF, tacrolimus or cyclosporine.

. Study population: In total 24 patients, men and women of at least 18 years of age, with perianal CD will be recruited. Patients with a minimum of one and a maximum of three fistula tracts.

Description of treatments: .

Subjects will receive:

Investigational product: CX-601 Suspension of adult expanded allogenic adipose-derived stem cells (eASCs) at a doses of 20 million cells and 40 million cells.

What is being measured

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

  1. Incidence of treatment emergent adverse-events

    Measured: 24 weeks

Secondary outcomes (5)
  1. The reduction in the number of draining fistulas

    Measured: weeks 10,12, 22 and 24

  2. The increase in the number of closed fistulas.

    Measured: weeks 12 and 24

  3. Percentage of subjects in whom, the external openings of treated perianal fistula have closed.

    Measured: week 12

  4. Percentage of subjects with MRI fistula healing (absence of collections >2cm)

    Measured: weeks 12 and 24

  5. Percentage of subjects presenting luminal relapse

    Measured: weeks 12 and 24.

Questions about this trial

What is this clinical trial studying?

A Phase 1/2 study testing Cx601 in people with Crohn's Disease and Anal Fistula, run by Tigenix S.A.U. at 6 sites in Spain.

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 5 inclusion and 21 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 12 Apr 2019. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 6 sites in Spain. 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.

What does this combined 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.

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

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?

Incidence of treatment emergent adverse-events (time frame: 24 weeks). 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 12 Apr 2019.
