New data

  • Data presented at the 65th ASH Annual Congress (9 – 12 December 2023) in San Diego (USA) showed that:
  • Safety:
    • Reni-cel was well-tolerated and demonstrated a safety profile consistent with myeloablative conditioning with busulfan and autologous hematopoietic stem cell transplant by all patients in the RUBY and EdiTHAL trials in the 17 patients (11 in the RUBY trial / SCD ; 6 in the EdiTHAL trial / thalassaemia) that have been infused thus far.
    • After reni-cel infusion, all treated patients with >2 months follow-up demonstrated successful neutrophil engraftment within one month and platelet engraftment within 1.6 months. No serious adverse events (SAEs) related to reni-cel treatment have been reported.
  • Efficacy:
    • In the EdiTHAL trial, 5 patients with >1 month follow-up demonstrated early and robust total hemoglobin and fetal hemoglobin increases, with total hemoglobin rising above the transfusion independence threshold of 9 g/dL.

New data

Data presented at the 28th EHA Annual Congress (9 – 11 June 2023) in Frankfurt (Germany) showed positive initial safety and efficacy data from the first transfusiondependent beta thalassemia patient treated in the EdiTHAL trial.

The first treated patient (male) has had 1.5 months of follow-up. Patient 1 had successful neutrophil and platelet engraftment within 30 days of infusion. No serious adverse events occurred after EDIT-301 infusion, and no adverse events reported were related to treatment with EDIT-301.

Achieved a fetal hemoglobin fraction of 34.9% representing 4 g/dL of total hemoglobin at 1.5 months post-treatment.
