Safety and Efficacy Study of Umbilical Cord Blood-Drived Mesenchymal Stem Cells to Promote Engraftment of Unrelated Hematopoietic Stem Cell Transplantation

April 20, 2012 updated by: Medipost Co Ltd.

Phase 1/2 Study of Umbilical Cord Blood-Drived Mesenchymal Stem Cells Infusion for Promotion of Engraftment and Prevention of an Graft Rejection and Graft-versus-Host Disease After Unrelated Hematopoietic Stem Cell Transplantation.

The purpose of this study is to evaluate the safety and efficacy of PROMOSTEM (human umbilical cord blood-derived mesenchymal stem cells) at a dose of 1 and 5x1,000,000 hMSC/kg in subject for the promotion of an engraftment and prevention of graft rejection and Graft-Versus-Host Disease after unrelated hematopoietic stem cell transplantation for children with acute leukemia.

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

Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

  • Hematopoietic stem cell transplantation (HSCT) is a procedure in which progenitor cells capable of reconstituting normal bone marrow function are administered to a patient. This procedure has been used to treat adults and children with life-threatening hematological malignancies and congenital immunodeficiency disorders.
  • In HSCT, therapeutic goal is an elimination of disease and enrichment of regenerating capacity to achieve engraftments resulting in continued generation of functional blood elements from the engrafted living cells. Transplantation of unrelated hematopoietic stem cells originating either from adult bone marrow or from peripheral blood often leads to graft-versus host-disease (GvHD), opportunistic infections and graft failure after transplantation.
  • In HSCT, MSC have been used as a therapy for GvHD and other complications. The aim of MSC infusions in HSCT is to use the cells' immunomodulatory effects to promote engraftment and to reduce the immunological reactions giving rise to GvHD.
  • There is a growing interest in co-transplantation of MSC and HSC to improve the donor outcome in the unrelated HSCT condition.

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.

What is the study measuring?

Primary Outcome Measures

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
Time Frame
- Day of neutrophil engraftment - Day of platelet engraftment - Evaluation of chimerism - Evaluation of engraftment rate
Time Frame: 28 and 100 days
28 and 100 days

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
