The Transfusions (3505) Form is a Gene Therapy registry form which captures any red blood cell (RBC) and platelet transfusions administered at any time post infusion.

This form will come due for those recipients enrolled onto CIBMTR study CS22-24 (Zyntelgo®). This is a post marketing prospective, multicenter, observational, long-term safety and effectiveness registry study of recipients with beta-thalassemia treated with Betibeglogene Autotemcel (Zynteglo®).

The Pre-Transplant Essential Data (2400) Form will confirm study eligibility, this includes event date, genetic modification, and gene therapy product infused. Once eligibility is confirmed, the Transfusion (3505) Form will come due along with the Post-Infusion Follow-Up (2100) Form for each timepoint, 100 days through 15 years annually, per FDA Gene Therapy Long Term Follow Up Guidelines.
