[{"type":"text","content":"\n- Both trials met the primary and key secondary endpoints at the pre-specified interim analysis -\n\n\n- Data continue to demonstrate transformative and durable benefit -\n\n\n- Safety profile consistent with busulfan conditioning and autologous hematopoietic stem cell transplant -\n\n\n BOSTON & ZUG, Switzerland--(BUSINESS WIRE)--\nVertex Pharmaceuticals Incorporated (Nasdaq: VRTX) and CRISPR Therapeutics (Nasdaq: CRSP) today announced that both pivotal trials for exagamglogene autotemcel (exa-cel) in patients with transfusion-dependent beta thalassemia (TDT) or severe sickle cell disease (SCD) met primary and key secondary endpoints at pre-specified interim analyses. The results are being presented at the Annual European Hematology Association (EHA) Congress.\n\n\n“The updated results from both the TDT and SCD trials are remarkable and bring the promise of an autologous CRISPR/Cas9 gene-edited cell therapy one-step closer to patients who are waiting,” said Carmen Bozic, M.D., Executive Vice President, Global Medicines Development and Medical Affairs, and Chief Medical Officer at Vertex.\n\n\n“This analysis confirms the potential of exa-cel to render patients transfusion-independent or VOC-free, with significant improvement in their quality of life and physical performance,” said Franco Locatelli, M.D., Ph.D., Professor of Pediatrics at the Sapienza University of Rome, Director of the Department of Pediatric Hematology and Oncology at Bambino Gesù Children’s Hospital. “This therapy offers the potential of a functional cure for patients with transfusion-dependent beta thalassemia or severe sickle cell disease along with a favorable safety profile.”\n\n\nNew Data From Pre-Specified Interim Analyses in exa-cel Pivotal Trials\n\n\nBoth CLIMB-111 and CLIMB-121 met their primary endpoint and key secondary endpoint at the pre-specified interim analysis for each trial. These analyses evaluated the efficacy and safety of exa-cel in patients with TDT or SCD in the ongoing Phase 3 trials as well as in the long-term follow up trial CLIMB-131. The data shared are from 83 patients (48 with TDT and 35 with SCD) dosed with exa-cel with follow-up up to 43.7 months. All patients treated with exa-cel demonstrated clinical benefit, and these data continue to demonstrate the potentially transformative profile of exa-cel.\n\n\nEfficacy of exa-cel ...
