Comings and Goings: Exagamglogene autotemcel (exa-cel) non-viral cell therapy for treatment of Sickle Cell Disease (SCD).
Findings: A phase 3, single-group, open-label study was conducted in patients 12 - 35 years of age with SCD (n=44) who had had at least 2 severe vaso-occlusive crises (VOC's) in each of the 2 years prior to screening. CD34+ HSPCs were edited with the use of CRISPR-Cas9 at the erythroid-specific enhancer region of BCL11A to reactive fetal hemoglobin synthesis. Before exa-cel infusion, patients underwent myeloablative conditioning with PK dose-adjusted busulfan. The primary end point was absence of severe VOC's for at least 12 consecutive months. A secondary end point was lack of hospitalization for severe VOC's crises for at least 12 consecutive months. Median follow-up was 19.3 months (range, 0.8 to 48.1). Safety was also assessed. Of the 30 patients who had sufficient follow-up to be evaluated, 29 (97%; 95% confidence interval [CI], 83 to 100) were free from VOC's for at least 12 consecutive months, and all 30 (100%; 95% CI, 88 to 100) were free from hospitalizations for VOC's for at least 12 consecutive months (P<0.001 for both comparisons vs a null hypothesis of a 50% response). The safety profile was generally consistent with that of myeloablative conditioning and autologous HSPC transplantation. No cancers were observed.

In collaboration with Vertex Pharmaceuticals, we're pleased to share that we’ve published three new publications in The New England Journal of Medicine (NEJM) containing clinical data on the treatment for sickle cell disease and beta thalassemia.
