Bone Marrow Transplant From Related Donor for Patients With High Risk Hemoglobinopathies

January 15, 2020 updated by: Robert Krance, Baylor College of Medicine

Allogeneic Bone Marrow Transplant From HLA Identical Related Donors for Patients With High Risk Hemoglobinopathies: Hemoglobin SS, Hemoglobin SC, Hemoglobin SB0/+ Thalassemia, or Homozygous B0/+ Thalassemia or Severe Variants of B0/+ Thalassemia

The major goal of this study is to determine the risks and benefits of bone marrow transplants in patients with severe thalassemia or sickle cell disease. Participation in this project will be for two years.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Terminated

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

To do the bone marrow transplant, we must first kill the cells in the bone marrow that make the abnormal red blood cells that are found in patients with severe thalassemia or sickle cell disease.

We will do this by using three drugs: busulfan, cyclophosphamide, and CAMPATH-1H. CAMPATH-IH is an investigational drug. CAMPATH-1H is used to prevent participants from rejecting or refusing to let the donor blood cells grow in the body. After the drug treatment, participants will be given bone marrow from a brother or sister who has healthy bone marrow that matches.

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

1 day to 64 years (Child, Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Description

Inclusion:

  • Patients with homozygous B0/+ thalassemia or severe variants of B0/+ thalassemia with an HLA genotypically identical donor.
  • Patients with an HLA genotype identical donor and hemoglobin SS, hemoglobin SC, or hemoglobin Sb 0/+ and at least one of the following:

Previous central nervous system vaso-occlusive episode with or without residual neurologic findings; Frequent painful vaso-occlusive episodes which significantly interfere with normal life activities and which necessitate chronic transfusion therapy; Recurrent SCD chest syndrome events which necessitate chronic transfusion therapy.

  • Severe anemia which prevents acceptable quality of life and necessitates chronic transfusion therapy.
  • The patient must have an HLA genotype identical donor.
  • Between the ages of birth and 65 years.
  • Women of childbearing potential must have a negative pregnancy test.

Exclusion:

  • Biopsy proven chronic active hepatitis or fibrosis with portal bridging.
  • SCD chronic lung disease >/= stage 3.
  • Severe renal dysfunction defined as creatinine clearance <40 ml/min/1.73 M2
  • Severe cardiac dysfunction defined as shortening fraction <25%.
  • HIV infection.
  • Severe but unspecified chronic toxicity serious enough to detrimentally affect the patient's capacity to tolerate bone marrow transplant (BMT).
  • Inadequate intellectual capacity to understand the nature and risk inherent in the BMT process and give informed consent (in the case of minors, this criteria must be fulfilled by the legal guardian).
  • Pregnant, lactating or unwilling to use appropriate birth control.

Study record dates

These dates track the progress of study record and summary results submissions to ClinicalTrials.gov. Study records and reported results are reviewed by the National Library of Medicine (NLM) to make sure they meet specific quality control standards before being posted on the public website.

Study Major Dates

Study Start

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.
August 1, 2000

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
November 21, 2003

Study Completion (Actual)

Study Completion

The date on which the last participant in a clinical study was examined or received an intervention/treatment to collect final data for the primary outcome measures, secondary outcome measures, and adverse events (that is, the last participant's last visit). The "anticipated" study completion date is the date that the researchers think will be the study completion date.
