What this trial studies

This study aims to collect real-world longitudinal data on individuals with β-thalassemia who have been treated with betibeglogene autotemcel (beti-cel) in a post-marketing setting. It focuses on assessing the long-term safety of the treatment, including the risk of newly diagnosed malignancies, as well as evaluating its long-term effectiveness. Participants will be followed by hematologists at participating centers in the US, and their data will be shared with the Center for International Blood and Marrow Transplant Research (CIBMTR).

Why it matters

Potential benefit: If successful, this study could provide valuable insights into the long-term safety and effectiveness of beti-cel treatment for patients with β-thalassemia.

How similar studies have gone: Other studies have shown success in collecting real-world data on gene therapies, making this approach promising but not entirely novel.
