We are highly encouraged by the initial data from our Phase 1 trial for CTX310, which demonstrates the power of our in vivo gene editing platform to deliver paradigm changing medicines to patients with serious cardiovascular disease,” said Samarth Kulkarni, Ph.D., Chairman and Chief Executive Officer of CRISPR Therapeutics. “Additionally, we are pleased with the continued progress of Casgevy and the broader pipeline, and we look forward to sharing further clinical updates in the months ahead.” Recent Highlights and Outlook In Vivo Liver Editing Programs CTX310™ targets ANGPTL3, a gene that encodes for key protein involved in the regulation of low-density lipoprotein (LDL) and triglyceride (TG) levels – both well-established risk factors for atherosclerotic heart disease (ASCVD). Loss-of-function mutations in ANGPTL3 are associated with significantly reduced levels of LDL and TGs, as well as reduced risk of ASCVD, without adverse effects on overall health. In the U.S. alone, more than 40 million patients are affected by elevated LDL, severely elevated TGs or both – representing a large addressable patient population. CTX310 is initially focused on a high-risk subset of this group with the greatest unmet medical need and limited effective treatment options. CTX310 is in an ongoing Phase 1 first-in-human dose escalation clinical trial targeting ANGPTL3 in four patient groups with elevated LDL, TG or both including homozygous familial hypercholesterolemia (HoFH), severe hypertriglyceridemia (sHTG), heterozygous familial hypercholesterolemia (HeFH), or mixed dyslipidemias (MDL) with levels of TG (>300 mg/dL) and/or LDL-C (>100 mg/dL); >70 mg/dL for subjects with ASCVD. TG and LDL, both of which are validated as surrogate endpoints for clinical benefit and accepted by regulatory agencies, were assessed at various timepoints.Top-line data reported today are from the first 10 patients across the first four cohorts (lean body weight-based doses of DL1 [0.1 mg/kg], DL2[0.3 mg/kg], DL3 [0.6 mg/kg] and DL4 [0.8 mg/kg]) with at least 30 days of follow-up for each participant as of a data cutoff date of April 16, 2025.A single dose of CTX310 demonstrated dose-dependent decreases in ANGPTL3, TGs, and LDL. Based upon ANGPTL3 knockdown, DL1 and DL2 were minimally active doses, whereas treatment at DL3 and DL4 resulted in reductions of up to 75% of baseline levels in ANGPTL3. CTX310 has been well-tolerated, with no treatment-related severe adverse events (SAEs) and no grade ≥3 adverse events (AEs) reported. No clinically significant changes in alanine aminotransferase (ALT), aspartate aminotransferase (AST), bilirubin, or platelets were observed at any dose level. There were no dose-dependent trends in any of these laboratory measurements.

The Company plans to present the CTX310 Phase 1 data at a medical meeting in the second half of 2025.CTX320 is in an ongoing Phase 1 clinical trial targeting the LPA gene in patients with elevated lipoprotein(a) [Lp(a)], a genetically determined risk factor associated with increased incidence of major adverse cardiovascular events (MACE). Elevated Lp(a) levels are prevalent in up to 20% of the global population. Dose escalation is ongoing, with an update expected in the second quarter of 2025.CRISPR Therapeutics continues to advance two preclinical programs: CTX340™, targeting angiotensinogen (AGT) for the treatment of refractory hypertension, and CTX450™, targeting 5’ aminolevulinic acid synthase 1 (ALAS1) for the treatment of acute hepatic porphyrias (AHP). Both candidates are currently in IND/CTA-enabling studies. Hemoglobinopathies and CASGEVY® (exagamglogene autotemcel [exa-cel])CASGEVY is approved in the U.S., Great Britain, the EU, the Kingdom of Saudi Arabia (KSA), the Kingdom of Bahrain (Bahrain), Canada, Switzerland and the United Arab Emirates (UAE) for the treatment of both SCD and TDT, and launches are ongoing. Building on the foundational launch in 2024, significant progress is being made to bring this transformative therapy to patients worldwide.As of May 1, more than 65 authorized treatment centers (ATCs) have been activated globally and approximately 90 patients have had their first cell collection. The number of new patients initiating cell collection is expected to grow significantly throughout 2025.Vertex has secured a formal reimbursement agreement with NHS England, enabling access to CASGEVY for patients with SCD. This follows an earlier agreement, reaching in August 2024, providing access for eligible patients with TDT. A similar reimbursement agreement has been established in Wales for eligible SCD and TDT patients. Following a positive assessment, national reimbursement was finalized in Austria. In the Middle East, reimbursement was also finalized across the majority of Emirates, following regulatory approval in the UAE.A manufacturing license application has been submitted to the U.S. Food and Drug Administration (FDA), with commercial production in Portsmouth, New Hampshire expected to begin in the second half of 2025. This submission is part of the planned ramp-up of CASGEVY manufacturing capacity as demand for the therapy increases.CRISPR Therapeutics continues to advance its next-generation approaches designed to significantly broaden the addressable patient population for SCD and TDT. The Company’s internally developed targeted conditioning program, an anti-CD117 (c-Kit) antibody-drug conjugate (ADC), remains on track in preclinical development. In parallel, the Company is making continued progress in its in vivo editing platform aimed at enabling direct editing of hematopoietic stem cells (HSC) without the need for conditioning. By potentially eliminating the need for conditioning, this approach could unlock access to transformative therapies for a significantly larger patient population. Immuno-Oncology and Autoimmune Disease ProgramsClinical trials are ongoing for its next-generation allogeneic CAR T product candidates, CTX112™ and CTX131™, targeting CD19 and CD70, respectively, across multiple indications. Both candidates incorporate novel potency edits which can lead to significantly higher CAR T cell expansion and cytotoxicity, potentially establishing them as best-in-class allogeneic CAR T products for their respective targets. CTX112 is being developed for hematologic malignancies and autoimmune diseases and has the potential to be best-in-class based on preliminary data. Encouraging clinical data from the ongoing Phase 1/2 clinical trial of CTX112 in relapsed or refractory B-cell malignancies supported the FDA’s decision to grant Regenerative Medicine Advanced Therapy (RMAT) designation for the treatment of relapsed or refractory follicular lymphoma and marginal zone lymphoma. CTX112 is also in an ongoing Phase 1 clinical trial in autoimmune diseases, including indications such as systemic lupus erythematosus (SLE), systemic sclerosis and inflammatory myositis. Preliminary safety, pharmacokinetic, and pharmacodynamic data from oncology trials support its potential in autoimmune indications. The Company plans to provide an update for both oncology and autoimmune disease in mid-2025.Clinical trials for CTX131™ are ongoing in both solid tumors and hematologic malignancies, with updates expected in 2025. In parallel, an Investigational New Drug (IND) application for glypican-3 (GPC3)-targeted gene-edited autologous CAR T program for the treatment of hepatocellular carcinoma has been opened by our partner, Roswell Park Comprehensive Cancer Center.CRISPR Therapeutics’ immuno-oncology and autoimmune disease efforts are supported by a wholly-owned, U.S. manufacturing facility located in Framingham, MA. This investment enables the production of clinical and commercial-stage good manufacturing practice (GMP) materials across the Company’s allogeneic cell therapy programs. Regenerative Medicine ProgramsCRISPR Therapeutics continues to advance its regenerative medicine efforts in Type 1 diabetes (T1D). In addition to CTX211, the Company continues to advance next-generation programs focusing on induced pluripotent stem cell (iPSC) derived, allogeneic, gene-edited, beta islet cell precursors. These approaches aim to achieve insulin independence in T1D patients without the need for chronic immunosuppression. The Company expects to provide an update in 2025.

About CASGEVY® (exagamglogene autotemcel [exa-cel]) CASGEVY is a non-viral, ex vivo CRISPR/Cas9 gene-edited cell therapy for eligible patients with SCD or 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 recurrent vaso-occlusive crises (VOCs) for patients with SCD and transfusion requirements for patients with TDT. CASGEVY is approved for certain indications in multiple jurisdictions for eligible patients. About the CRISPR Collaboration and Vertex CRISPR Therapeutics and Vertex entered into a strategic research collaboration in 2015 focused on the use of CRISPR/Cas9 to discover and develop potential new treatments aimed at the underlying genetic causes of human disease. CASGEVY represents the first potential treatment to emerge from the joint research program. Under an amended collaboration agreement, Vertex now leads global development, manufacturing, and commercialization of CASGEVY and splits program costs and profits worldwide 60/40 with CRISPR Therapeutics. Vertex is the manufacturer and exclusive license holder of CASGEVY. About CTX112CTX112 is being developed for both oncology and autoimmune indications. CTX112 is a next-generation, wholly-owned, allogeneic CAR T product candidate targeting Cluster of Differentiation 19, or CD19, which incorporates edits designed to evade the immune system, enhance CAR T potency, and reduce CAR T exhaustion. CTX112 is being investigated in an ongoing clinical trial designed to assess safety and efficacy of the product candidate in adult patients with relapsed or refractory B-cell malignancies who have received at least two prior lines of therapy. In addition, CTX112 is being investigated in an ongoing clinical trial designed to assess the safety and efficacy of the product candidate in adult patients with systemic lupus erythematosus, systemic sclerosis, and inflammatory myositis. About CTX131CTX131 is being developed for both solid tumors and hematologic malignancies, including T cell lymphomas (TCL).
