About this study

Official title: an Open Label Trial of Evaluation of the Safety and Efficacy of Treatment With γ-globin Reactivated Autologous Hematopoietic Stem Cells in Subjects With β-thalassemia Major

This is a non-randomized, open label, single-dose, phase 1/2 study in up to 12 participants with β-thalassemia major.This study aims to evaluate the safety and efficacy of the treatment with γ-globin reactivated autologous hematopoietic stem cells in subjects with β-thalassemia major.

Read the detailed description

γ-globin reactivated autologous hematopoietic stem cells will be manufactured using Crispr/Cas9 gene editing system. Subject participation for this study will be 1 year. Subjects who enroll in this study will be asked to participate in a subsequent long-term follow up study that will monitor the safety and efficacy of the treatment they receive for up to 15 years post-transplant.

Being tested
γ-globin reactivated autologous hematopoietic stem cells

What is being measured

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

  1. Safety evaluation of γ-globin reactivated autologous hematopoietic stem cells

    Proportion of subjects with engraftment; Overall survival.

    Measured: up to 24 months post transplant

  2. Incidence and severity of adverse events as a measure of safety and tolerability. Adverse events assessed according to NCI-CTCAE v5.0 criteria

    Incidence of AEs and SAEs post transplant

    Measured: up to 24 months post transplant

Secondary outcomes (1)
  1. Efficacy evaluation of γ-globin reactivated autologous hematopoietic stem cells

    Proportion of subjects achieving transfusion independence for at least 6 months (TI6); Proportion of subjects achieving TI12; Proportion of alleles with intended genetic modification in bone marrow cells; Change in total hemoglobin concentration; Change from baseline in annualized frequency and volume of packed RBC transfusions.

    Measured: up to 24 months post transplant

Questions about this trial

What is this clinical trial studying?

A study testing γ-globin reactivated autologous hematopoietic stem cells in people with β Thalassemia Major, run by Bioray Laboratories at 1 site in China.

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 4 inclusion and 14 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 5 Jan 2024. 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 China. 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?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

Safety evaluation of γ-globin reactivated autologous hematopoietic stem cells (time frame: up to 24 months post transplant). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT04211480, which also lists 2 linked publications.

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 5 Jan 2024.
