A Study of Participants with Β-Thalassemia Treated with Betibeglogene Autotemcel

February 10, 2025 updated by: bluebird bio

A Safety and Effectiveness Registry Study of Patients with Β-Thalassemia Treated with Betibeglogene Autotemcel (the Glostar Registry)

The main aim of this study is to collect real-world longitudinal data on participants with β-thalassemia treated with betibeglogene autotemcel (beti-cel) in the post marketing setting. To assess the long-term safety, including the risk of newly diagnosed malignancies, after treatment with beti-cel and evaluate the long-term effectiveness of treatment with beti-cel.

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.

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

  • Child
  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

Sampling Method

Non-Probability Sample

Study Population

Participants with β-thalassemia treated with beti-cel in the post marketing setting at a center in the United States (US) that participates in the Registry.

Description

Inclusion Criteria:

  • Participant must be treated with beti-cel in the post marketing setting at a center in the US that participates in the Registry.
  • Participant must sign an informed consent and/or assent prior to enrollment as required under applicable laws and regulations.
  • Participant must have signed an informed consent and/or assent permitting data to be shared with Center for International Blood and Marrow Transplant Research (CIBMTR).
  • Participant must be followed by a hematologist based in the US.

Exclusion Criteria:

- There are no exclusion criteria for Registry participation.

Cohorts and Interventions

Group / Cohort

Group / Cohort

A group or subgroup of participants in an observational study that is assessed for biomedical or health outcomes.
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.
All Participants
Participants with β-thalassemia treated with beti-cel in the post-marketing setting will be followed in this registry study for up to 15 years after infusion with beti-cel to collect real-world longitudinal data.
Other: No Intervention
This is non-interventional study.

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.
Outcome Measure
Measure Description
Time Frame
Number of Participants who Experience Each Individual Adverse Events of Interest (AEIs)
Time Frame: Through 15 years post-beti-cel infusion

The Sponsor considers the following events to be AEIs (which should be reported as a medically significant Serious Adverse Event [SAE]):

  • Any newly diagnosed malignancy
  • Neutrophil engraftment failure: defined as healthcare provider (HCP) decision to administer back-up cells or subsequent hematopoietic stem cell transplantation (HSCT) due to neutrophil recovery failure
  • Newly acquired human immunodeficiency virus-1 (HIV-1), HIV-2 infection and human t-lymphotropic virus (HTLV) infection
  • Any newly diagnosed autoimmune disorder
  • Any hepatic veno-occlusive disease (VOD)
  • Any clinically significant bleeding events.
Through 15 years post-beti-cel infusion

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Time Frame
Number of Participants with Serious Adverse Events (SAEs)
Time Frame: Through 15 years post-beti-cel infusion
Through 15 years post-beti-cel infusion
Number of Participants with beti-cel related AEs
Time Frame: Through 15 years post-beti-cel infusion
Through 15 years post-beti-cel infusion
Event-Free Survival
Time Frame: Through 15 years post-beti-cel infusion
