Gene Editing Race Between Editas and Vertex, CRISPR Heats Up

The gene editing race between Editas Medicine and Vertex Pharmaceuticals with CRISPR Therapeutics has heated up as both companies released positive data for their sickle cell disease (SCD) and transfusion-dependent beta thalassemia (TDT) hopeful treatments. Editas Medicine unveiled early data from the RUBY and EdiTHAL trials on Friday, demonstrating the potential of its gene editor EDIT-301 in treating SCD and TDT. Meanwhile, Vertex Pharmaceuticals and CRISPR Therapeutics announced that the FDA had accepted the BLAs for exagamglogene autotemcel (exa-cel), their investigational CRISPR-based, gene-edited therapy for these indications. The partners also revealed that 16 out of 17 evaluable SCD patients met the primary endpoint of freedom from vaso-occlusive crises (VOC) for at least 12 consecutive months following exa-cel treatment. Both Editas and Vertex/CRISPR will present their respective data at the ongoing European Hematology Association Congress.
