Trial summary

Betathalassemia major is a disease of the blood and bone marrow. You were born with it and it has made you unable to make normal hemoglobin and red cells. You have been receiving red blood cell transfusions all your life. These transfusions do not cure your disease. Read more about this study

About this study

Official title: A Pilot Trial to Assess the Feasibility and Safety of GCSF Mobilization of CD34+ Hematopoietic Progenitor Cells in Patients With Betathalassemia Major

Betathalassemia major is a disease of the blood and bone marrow. You were born with it and it has made you unable to make normal hemoglobin and red cells. You have been receiving red blood cell transfusions all your life. These transfusions do not cure your disease. The problem with transfusions is that they contain a lot of iron. With time iron builds up in your body and will eventually hurt some of your organs . Because of this buildup of iron , you are taking medicine that helps your body get rid of the extra iron.

Today, the only other treatment is bone marrow or stem cell transplant. It can only be done when a matched donor is available. This is most often a brother, sister, or parent. Bone marrow transplant may cure betathalassemia major. If you have a transplant and it is successful, you will no longer have the disease. Without a matched sibling or parent, the standard treatment is to keep having transfusions.

In the near future, we will be testing a new treatment for making normal hemoglobin and normal red blood cells. We have recreated the healthy hemoglobin gene in a test tube. We are able to use it and put it back into cells. This is called gene therapy. We have been able to put this gene into the stem cells of mice with thalassemia. These mice were cured. We now plan to take that gene and put it into stem cells from people who have betathalassemia major. We will then inject those stem cells back into that person's blood.

In general, we can obtain more stem cells from the blood of a person than from the bone marrow . In order to do so, we must give that person a blood growth factor. The growth factor stimulates the bone marrow to make more stem cells. That growth factor is called granulocyte colony stimulating factor (GCSF), or Filgrastim.

The purpose of this trial is to find out if the drug GCSF has any side effects on you, and if you will make more stem cells in response to it. This trial is not a gene therapy trial. This trial will not help your thalassemia.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • GCSF, Central venous line placement, Stem cell Collection (leukapheresis)Genetic

    Daily injections under the skin of a GCSF. This is done for 5 to 6 days. On days 1, 3,5, and if need on day 6. To collect stem cells, we need good access to this blood. If the patient has good veins, we do this by placing an IV on each one of their arms. The peripheral blood stem cell collection is usually an outpatient procedure and takes about 3 to 4 hours. You will have blood work and a physical exam on days one, three, and five while you are getting GCSF.

    These will be done again 24 hours after your stem cells are collected.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Number of Participants With no Serious Adverse Events

    The entered value represents the number of participants with the absence of serious adverse events. G-CSF mobilization will be considered safe if there are no more than 1 of 5 patients with SAEs

    Measured: Up to 14 Days

Questions about this trial

What is this clinical trial studying?

A study testing GCSF, Central venous line placement, Stem cell Collection (leukapheresis) in people with Beta Thalassemia Major and Congenital Anemias, run by Memorial Sloan Kettering Cancer Center at 1 site 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 9 inclusion and 6 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: finished, as of the sponsor's last update on 25 Nov 2016. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site 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.

Are results available for this study?

Yes. Results are posted in the registry (first posted 25 Nov 2016). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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.

What does the primary outcome measure?

Number of Participants With no Serious Adverse Events (time frame: Up to 14 Days). It is what the study was designed to measure, not a finding.

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 25 Nov 2016.
