Effectiveness was established based on achievement of transfusion independence, which is attained when the participant maintains a predetermined level of hemoglobin without needing any red blood cell transfusions for at least 12 months. Of 41 participants receiving betibeglogene autotemcel, 89% achieved transfusion independence. [5]

[10] The experimental procedure resulted in "no complications". [10] Relapse is possible, even after treatment by argon plasma coagulation and progesterone. [21]
