    β-thalassemia is an inherited disorder characterized by reduced β-chain production in hemoglobin, leading to ineffective erythropoiesis and anemia.

  • 2

    Exagamglogene autotemcel (exa-cel) is a CRISPR-Cas9 gene therapy that aims to reactivate fetal hemoglobin synthesis in patients with transfusion-dependent β-thalassemia.

  • 3

    In the Phase 3 CLIMB THAL-111 study, exa-cel treatment resulted in transfusion independence for 91.4% of participants with normal hemoglobin levels.

  • 4

    The study analyzed biomarkers of erythropoiesis and iron homeostasis before and after iron removal therapy in patients treated with exa-cel.

  • 5

    Iron overload in β-thalassemia patients results from ineffective erythropoiesis and repeated RBC transfusions, leading to serious organ complications.
