Recent Highlights and Outlook

Hemoglobinopathies and CASGEVY^® (exagamglogene autotemcel)

• CASGEVY, the world’s first approved CRISPR-based therapy, has been shown to reduce or eliminate vaso-occlusive crises (VOCs) in eligible patients with sickle cell disease (SCD) and transfusion requirements in eligible patients with transfusion-dependent beta thalassemia (TDT). CASGEVY is approved in 39 countries across North America, Europe, and the Middle East for eligible patients 12 years of age and older, with approvals for younger children in five of those countries.
• CASGEVY generated third quarter 2026 revenue of $99 million, representing 30% growth quarter-over-quarter and nearly six times the revenue reported in the third quarter of 2025. Twice as many in the first nine months of 2026 as in all of 2025, and more than 750 patients have initiated treatment worldwide.
• CASGEVY’s availability for younger patients continues to expand. In July, the FDA approved CASGEVY for children 2 years of age and older with SCD or TDT, making it the first genetic therapy for SCD and TDT approved for this age group, and multiple children have since initiated treatment in the U.S. The Kingdom of Saudi Arabia, the United Arab Emirates, and the Kingdom of Bahrain have also approved CASGEVY for children 2 years of age and older, and the U.K. Medicines and Healthcare products Regulatory Agency (MHRA) approved CASGEVY for children 5 years of age and older with severe SCD or TDT.
• Building on CASGEVY, CRISPR Therapeutics is advancing an in vivo hematopoietic stem cell editing approach that could extend gene editing to many more patients with SCD and TDT. Using lipid nanoparticle (LNP)-mediated delivery, the approach is designed to edit stem cells directly in the body, potentially simplifying treatment and broadening global access.
  
  

In Vivo Liver Editing

CRISPR Therapeutics continues to advance a diversified portfolio of in vivo gene editing programs leveraging its proprietary liver-directed LNP delivery platform.

• The Phase 1 clinical trial of CTX310^®, targeting angiopoietin-related protein 3 (ANGPTL3) is ongoing.
• CRISPR Therapeutics today announced that the U.S. Food and Drug Administration (FDA) has granted Regenerative Medicine Advanced Therapy (RMAT) designations to CTX310 for the treatment of severe hypertriglyceridemia (sHTG) and for the treatment of patients with elevated LDL-C. RMAT designation provides the benefits of Fast Track and Breakthrough Therapy designations, including early interactions with the FDA and potential eligibility for priority review and accelerated approval.
• In August, CRISPR Therapeutics presented Phase 1a durability data for CTX310 in a late-breaking session at the European Society of Cardiology (ESC) Congress 2026 and simultaneously published in The New England Journal of Medicine. A single course treatment of CTX310 produced deep and durable reductions in circulating ANGPTL3, triglycerides (TG), and low-density lipoprotein (LDL) that were sustained through one year of follow-up. At the highest dose, the mean reductions from baseline were 79% in ANGPTL3, 48% in triglycerides, and 53% in LDL-C in a mixed patient cohort with high triglycerides, high LDL-C, or both. CTX310 was well tolerated with no treatment-related serious adverse events.
• Phase 1b data in patients with sHTG will be presented in a late-breaking oral presentation at the American Heart Association (AHA) Scientific Sessions 2026 on November 9, 2026, at 8:00 a.m. CT. 
• The Phase 1 clinical trial of CTX340™, targeting angiotensinogen (AGT), in patients with refractory hypertension is ongoing.

About CASGEVY^® (exagamglogene autotemcel [exa-cel])

CASGEVY^® is a non-viral, ex vivo CRISPR/Cas9 gene-edited cell therapy for eligible patients with sickle cell disease (SCD) or transfusion-dependent beta thalassemia (TDT), in which a patient’s own hematopoietic stem and progenitor cells are edited at the erythroid specific enhancer region of the BCL11A gene. This edit results in the production of high levels of fetal hemoglobin (HbF; hemoglobin F) in red blood cells. HbF is the form of the oxygen-carrying hemoglobin that is naturally present during fetal development, which then switches to the adult form of hemoglobin after birth. CASGEVY has been shown to reduce or eliminate VOCs for patients with SCD and transfusion requirements for patients with TDT. CASGEVY is approved for eligible SCD and TDT patients 12 years and older by multiple regulatory bodies around the world, and for younger children in select countries.
