Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 1 day to 65 years
  • All sexes
  • No healthy volunteers
  • Child, Adult, Older adult

Who may be able to join

  • Patients with a haploidentical related HLA donor and hemoglobin SS, hemoglobin SC, or hemoglobin Sb0/+ thalassemia and at least one of the following conditions:
  • 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.
  • Patients with a haploidentical related HLA donor and homozygous b0/+ thalassemia or severe variants of b0/+ thalassemia and require chronic transfusion therapy.
  • Women of childbearing potential must have a negative pregnancy test.
  • Between the ages of birth and 65 years.

Who cannot join

  • HLA identical or 5/6 HLA matched sibling donor
  • Biopsy proven chronic active hepatitis or portal fibrosis.
  • 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.
  • Unspecified chronic toxicity serious enough to detrimentally affect the patient's capacity to tolerate Stem Cell Transplant.
  • Patient or guardian(s) unable to understand the nature and risks inherent in the stem cell transplant process.
  • Pregnant or lactating females and those unwilling to use acceptable contraception.

About this study

Official title: Allo SCT From HLA Haploidentical Related Donors Using Sub-Myeloablative Conditioning For Patients With High Risk Hemoglobinopathies: Hemo SS, Hemo SC, Hemo SB0/+ Thalassemia, Homozygous B0/+ Thalassemia or Severe B0/+ Thalassemia Variants

The major goal of this study is to determine the risks and benefits of stem cell transplants in combination with a newer, less toxic conditioning chemotherapy treatment in patients with severe sickle cell disease (SCD) or sickle hemoglobin variants (hemoglobin SC or hemoglobin SB0/+), or homozygous b0/+ thalassemia or severe B0/+ thalassemia variants. Participation in this project will be for one year, with follow up evaluations done every 6 months thereafter for 10 years or until participants are 18 years old.

Read the detailed description

To do the stem cell transplant, we must first kill most of the cells in the bone marrow that make the sickle hemoglobin or abnormal blood cells of severe beta thalassemia. We will do this by using a single dose of body irradiation and two drugs called Fludarabine and Campath-IH.

The treatment schedule is as follows:

Day - 6: Total body irradiation Day - 5: Fludarabine and Campath 1H Day - 4: Fludarabine and Campath 1H Day - 3: Fludarabine and Campath 1H Day - 2: Fludarabine and Campath 1H Day - 1: REST Day 0: Stem Cell Transplant (infusion)

After the drug treatment, participants will be given healthy stem cells from a related donor that partially matches their HLA (immune) type, most likely from a parent or sibling. This is known as the stem cell transplant.

The healthy stem cells will be put into a blood vein in the same way that transfusions are given. The cells then travel to the right places in the body, where they should grow and make new blood cells that do not sickle.

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing FLUDARABINE, CAMPATH-IH and Total Body Irradiation in people with Sickle Cell Anemia and Hemoglobinopathy, run by Baylor College of Medicine at 2 sites in United States.

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 8 inclusion and 8 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: stopped early, as of the sponsor's last update on 18 Jan 2020. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites in United States. 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 phase mean?

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 was stopped early (reason given: unable to accrue patients). Results are not available in the source record.

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.

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 18 Jan 2020.
