Summary

Phase 3 clinical results show 100% of treated patients achieved sustained remission from sickle cell disease symptoms.

Results from a pivotal Phase 3 clinical trial published today in Nature Medicine demonstrate that a one-time CRISPR-based gene therapy achieved complete and sustained remission in all 45 patients treated for severe sickle cell disease.

Patients who received the therapy, designated CTX001, showed elimination of vaso-occlusive crises and no longer required blood transfusions, with benefits sustained for more than 24 months in the longest-followed patients.

The results are expected to accelerate the already-submitted regulatory applications in the US, EU, and UK, with FDA approval potentially coming within months.
