Allogeneic Adipose Tissue-derived Mesenchymal Stem Cells for the Induction of Remission in Ulcerative Colitis (ALOASCU)

July 31, 2013 updated by: Instituto de Investigación Hospital Universitario La Paz

A Phase I/IIa Clinical Trial to Evaluate Safety and Efficacy of Adipose Tissue-derived Mesenchymal Stem Cells (ASC) on Induction to Remission in Ulcerative Colitis

The aims of our study are to evaluate the feasibility and safety of endoscopic injection of adipose tissue-derived mesenchymal stem cells in human subjects with moderate active ulcerative colitis, assessing the absence of adverse events associated to the investigational drug, and to evaluate the efficacy of the treatment to induce remission of moderate active ulcerative colitis, by improvements in disease activity index, quality of life index, and endoscopic index.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Mesenchymal stem cells (MSC) may be a therapeutic option in diseases associated with severe inflammation or auto-immune diseases, due to their immunomodulatory and anti-inflammatory properties. A number of clinical trials are being conducted worldwide testing th efficacy of MSC, mainly isolated from bone marrow, for different conditions, such as Graft Versus host Disease, refractory Crohn's Disease, ischemic stroke, acute myocardial infarction, type I Diabetes Mellitus, or Chronic Obstructive Pulmonary Disease. Usually, the route of administration of the cells in these studies is intravenous. Local injection of MSC for fistulizing Crohn's Disease has proven efficacious. Endoscopy is a routinary technique for the evaluation of gastrointestinal and colonic conditions. The purpose of our study is to evaluate safety and efficacy of the intracolonic injection by using a colonoscope of allogeneic adipose tissue-derived MSC in patients with moderate active ulcerative colitis.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

Experimental: allogeneic ASCs
Treatment consists in a cell suspension (5 million cells/mL) in aseptic buffered solution containing human expanded adipose-derived stem cells (eASCs) of allogeneic origin in disposable vials with no preservative agents. The cells will be given in different sites within the affected colonic submucosa at a total dose of 60 million cells with the use of a colonoscope.

What is the study measuring?

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
