Multi Donor Mismatched Stem Cell Transplantation (MDT)

February 18, 2016 updated by: SHAPIRA MICHAEL, Hadassah Medical Organization

Enhancement of Hematopoietic Stem Cell Engraftment by Multi Donor Stem Cell Transplantation (MDT) From 2 Mismatched Donors, a Phase I-II Open Study

The proposed research focuses on the development of innovative protocol of mismatched stem cell transplantation with combined 2 different haplo stem cell transplantation (SCT) donors which are mismatched to the recipient (and preferably to each other), in a patient in need for SCT, lacking an HLA match related or an unrelated donor. This innovative protocol named multi donor stem cell transplantation (MDT) is designed to facilitate engraftment even when reduced intensity conditioning or a low cell dose are used, improve the graft vs. leukemia (GVL) effect and enhance immune reconstitution (using quantitative and qualitative parameters).

Study Overview

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.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.

Enrollment (Anticipated)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.

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.

Ages Eligible for Study

No older than 70 years (Child, Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Description

Inclusion criteria:

  1. Patient age 0-70 years old with leukemia in 1st remission at high risk of relapse because of unfavorable prognostic features, at 2nd CR or MDS without an readily available matched donor (related or unrelated).
  2. Patients must have a mismatched donor willing and capable of donating peripheral blood stem cells and/or bone marrow progenitor cells using conventional techniques, and lymphocytes if indicated (mismatched defined as 3/6-4/6 HLA matching).
  3. Each patient / patient's guardian must sign written informed consent.
  4. Patients must have an ECOG PS ≤ 2; Creatinine <2.0 mg/dl; Ejection fraction >40%; DLCO >50% of predicted; Serum bilirubin <3 gm/dl; elevated GPT or GOT <3 x normal values.

Exclusion criteria:

  1. Not fulfilling any of the inclusion criteria.
  2. Not in CR (if the indication for transplant is leukemia).
  3. Active life-threatening infection.
  4. Overt untreated infection.
  5. HIV seropositivity, Hepatitis B or C antigen positivity with evidence of active hepatitis.
  6. Pregnant or lactating women.
  7. Donor contraindication (HIV seropositive confirmed by Western Blot, Hepatitis B antigenemia, HCV, evidence of bone marrow disease, unable to donate bone marrow or peripheral blood due to concurrent medical condition).
  8. Previous autologous or allogeneic stem cell transplantation.
  9. Inability to comply with study requirements.

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.
