CTX-112

There were no reported dose limiting toxicities (DLTs) and no reported Grade ≥3 infections. All grade 3 or 4 cytopenias (i.e., neutropenia, thrombocytopenia, anemia) following lymphodepleting chemotherapy resolved to Grade 2 or better within 1 month of CTX112 infusion. There were no reported cases of Graft versus Host Disease (GvHD), All cases of cytokine release syndrome (CRS) and immune effector cell-associated neurotoxicity syndrome (ICANS) were Grade 1 or 2 per the American Society for Transplantation and Cellular Therapy (ASTCT) criteria. These low-grade CRS and ICANS events followed standard toxicity management protocols. Objective and complete responses were seen at all dose levels and in all treated NHL subtypes (i.e., FL, MZL, MCL and LBCL). Responses were also seen in patients with poor prognostic factors including primary refractory disease, early relapse, and high baseline tumor burden (e.g., SPD > 4000 mm2). Five patients (of the 12 treated) have achieved responses lasting for more than 6 months, including one patient whose 6-month response was confirmed after the data cut-off date. One patient treated at DL1 remains in complete remission over a year after initial CTX112 infusion. The clinical efficacy of CTX112 is supported by a clearly differentiated pharmacokinetic profile for an allogeneic CAR T cell therapy. The mean peak concentration and total exposure were significantly higher at DL3 and DL4 vs. DL1 and DL2. This dose dependence suggests the possibility of deeper and more durable responses as the trial moves from dose escalation to dose optimization. Comparing DL3, the addition of Regnase-1 and TGFβR2 edits results in 7-fold higher peak concentration (Cmax) and 9.7-fold higher mean area under the curve (AUC) for CTX112 relative to CTX110®. Furthermore, at DL4, both Cmax and AUC are showing significantly more consistent and predictable increases. This suggests that the novel CRISPR/Cas9 potency edits are leading to higher CAR T cell expansion and functional persistence without enhanced or increased lymphodepleting chemotherapy doses.

In parallel, we remain focused on advancing our portfolio of clinical trials across oncology, autoimmune, diabetes and cardiovascular indications in a capital efficient manner. We look forward to a number of important data catalysts over the next 9-12 months as we advance our portfolio.” Recent Highlights and Outlook Hemoglobinopathies and CASGEVY™ (exagamglogene autotemcel [exa-cel]) CASGEVY has received regulatory approvals for the treatment of patients 12 years of age and older with sickle cell disease (SCD) and transfusion-dependent beta thalassemia (TDT) in Switzerland and Canada. CASGEVY is also approved in the U.S., Great Britain, the European Union (EU), the Kingdom of Saudi Arabia (KSA), and the Kingdom of Bahrain (Bahrain) for the treatment of both SCD and TDT, and launches are ongoing. CASGEVY is a collaboration product between CRISPR Therapeutics and Vertex Pharmaceuticals, and as part of an amendment to the collaboration agreement in 2021, Vertex now leads global development, manufacturing, regulatory and commercialization of CASGEVY with support from CRISPR Therapeutics. As of mid-October, 45 authorized treatment centers (ATCs) have been activated globally, including centers in all regions where CASGEVY is approved, and approximately 40 patients have already had at least one cell collection across all regions. Vertex announced a reimbursement agreement with NHS England for eligible TDT patients to access CASGEVY. They have also entered into commercial discussions with NHS England to secure access to CASGEVY for eligible patients with SCD. The Italian Medicines Agency (IMA) approved the request for the implementation of an early access program (EAP), for the use of CASGEVY for the treatment of TDT and SCD. Enrollment has been completed in two global Phase 3 studies of CASGEVY in children 5 to 11 years of age with SCD or TDT and the trials are ongoing. CRISPR Therapeutics has two next generation approaches with the potential to significantly expand the addressable population with SCD and TDT. The Company continues to advance its internally developed targeted conditioning program, an anti-CD117 (c-Kit) antibody-drug conjugate (ADC), through preclinical studies. Additionally, the Company has ongoing research efforts to enable in vivo editing of hematopoietic stem cells. This work could obviate the need for conditioning altogether, expand geographic reach, and enable the treatment of multiple additional other diseases beyond SCD and TDT. Immuno-Oncology and Autoimmune Diseases CRISPR Therapeutics’ next generation allogeneic CAR T candidates reflect the Company’s mission of innovating continuously to bring potentially transformative medicines to patients as quickly as possible. Clinical trials are ongoing for the Company’s next generation CAR T product candidates, CTX112™ and CTX131™, targeting CD19 and CD70, respectively, across multiple indications. CTX112 and CTX131 both contain novel potency edits which can lead to significantly higher CAR T cell expansion and cytotoxicity, potentially representing best-in-class allogeneic CAR T products for these targets. CRISPR Therapeutics announced that it will present a poster from the Company’s ongoing Phase 1 dose escalation study evaluating the safety and efficacy of CTX112, a next-generation CD19 allogeneic CAR T cell therapy, in relapsed or refractory (r/r) CD19-positive B-cell malignancies at the American Society of Hematology (ASH) 2024 Annual Meeting. The ASH abstract includes preliminary data on nine high-risk/heavily pretreated lymphoma patients showing an overall response rate (ORR) of 67% across multiple histologies and a complete response rate (CRR) of 44%, with four patients having achieved responses lasting for more than 6 months, including one patient treated at DL1 who remains in complete remission over a year after CTX112 infusion. Concordant with efficacy, pharmacokinetic (PK) data showed rapid cell expansion for CTX112 with many fold improvements in PK compared to the previous generation CTX110® CAR T. No dose limiting toxicities (DLTs) or adverse events (AEs) of graft versus host disease, hemophagocytic lymphohistiocytosis, or grade (Gr) ≥3 infections were observed, in addition to no Gr ≥3 cytokine release syndrome (CRS), or Gr ≥2 immune effector cell associated neurotoxicity syndrome (ICANS). Compared with first generation allogeneic CAR T therapies like CTX110, CTX112 results in better efficacy at lower doses, higher response rates, and improved PK. These data provide the first clinical evidence that disruptions in the genes encoding Regnase-1 and transforming growth factor beta receptor 2 can lead to increased expansion and functional persistence of CAR T cells. The poster presentation will include additional results from the trial. CTX112 is also in a Phase 1 clinical trial in systemic lupus erythematosus (SLE), with the potential to expand into additional autoimmune indications in the future. Early clinical studies conducted by third parties have shown that CD19-directed autologous CAR T therapy can produce long-lasting remissions in multiple autoimmune indications by deeply depleting B cells. The Company’s first generation allogeneic CD19-directed CAR T program has demonstrated effective depletion of B cells in oncology settings, which supports the potential for CTX112 in autoimmune diseases. CTX131 is currently in ongoing clinical trials in solid tumors and hematologic malignancies including T cell lymphomas (TCL). The Company plans to announce an update from the Phase 1 solid tumor trial in 2025. In certain hematologic malignancies such as TCL, allogeneic CAR T approaches may have greater potential to meet the unmet need in this patient population given the patients’ own T cells are not suitable for autologous manufacturing. In Vivo CRISPR Therapeutics has established a proprietary lipid nanoparticle (LNP) platform for the delivery of CRISPR/Cas9 to the liver. The first two in vivo programs utilizing this proprietary platform, CTX310™ and CTX320™, are directed towards validated therapeutic targets associated with cardiovascular disease. CTX310 is currently in an ongoing Phase 1 clinical trial targeting ANGPTL3 in patients with homozygous familial hypercholesterolemia (HoFH), severe hypertriglyceridemia (SHTG), heterozygous familial hypercholesterolemia (HeFH), or mixed dyslipidemias. Natural loss-of-function mutations in ANGPTL3 are associated with reduced low-density lipoprotein (LDL-C), triglycerides (TG) and atherosclerotic cardiovascular disease (ASCVD) risk without any negative impact on overall health. CRISPR Therapeutics expects to provide an update from this program in 2025. CTX320 is currently in an ongoing Phase 1 clinical trial targeting LPA in patients with elevated lipoprotein(a) [Lp(a)], which has shown to have an independent association with major adverse cardiovascular events (MACE). Up to 20% of the global population has elevated Lp(a) levels. CRISPR Therapeutics expects to provide an update from this program in 2025. The Company continues to advance two additional 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). CRISPR Therapeutics is conducting IND/CTA-enabling studies and expects to initiate both clinical trials in the second half of 2025. Regenerative Medicine CTX211™, an allogeneic, gene-edited, stem cell-derived beta islet cell precursor, is currently in an ongoing Phase 1 clinical trial for the treatment of Type 1 Diabetes (T1D). CRISPR Therapeutics remains committed to its goal of developing a beta-cell replacement product that does not require chronic immunosuppression. Vertex has non-exclusive rights to certain CRISPR Therapeutics’ CRISPR/Cas9 technology to accelerate development of potentially curative cell therapies for T1D. CRISPR Therapeutics remains eligible for development milestones and would receive royalties on any future products resulting from this agreement.

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 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 Therapeutics-Vertex Collaboration 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 CTX112 CTX112 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 CD19-positive 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 safety and efficacy of the product candidate in adult patients with system lupus erythematosus. About CTX131 CTX131 is being developed for both solid tumors and hematologic malignancies, including T cell lymphomas (TCL). CTX131 is a next-generation, wholly-owned, allogeneic CAR T product candidate targeting Cluster of Differentiation 70, or CD70, an antigen expressed on various solid tumors and hematologic malignancies. CTX131 incorporates edits designed to evade the immune system, prevent fratricide, enhance CAR T potency and reduce CAR T exhaustion. CTX131 is being investigated in ongoing clinical trials designed to assess the safety and efficacy of the product candidate in adult patients with relapsed or refractory solid tumors and hematologic malignancies, including TCL. About In Vivo Programs CRISPR Therapeutics has established a proprietary lipid nanoparticle (LNP) platform for the delivery of CRISPR/Cas9 to the liver. The Company’s in vivo portfolio includes its lead investigational programs, CTX310 (directed towards angiopoietin-related protein 3 (ANGPTL3)) and CTX320 (directed towards LPA, the gene encoding apolipoprotein(a) (apo(a)), a major component of lipoprotein(a) [Lp(a)]). Both are targeting validated therapeutic targets for cardiovascular disease. CTX310 and CTX320 are in ongoing clinical trials in patients with heterozygous familial hypercholesterolemia, homozygous familial hypercholesterolemia, mixed dyslipidemias, or severe hypertriglyceridemia, and in patients with elevated lipoprotein(a), respectively. In addition, the Company’s research and preclinical development candidates include CTX340 and CTX450, targeting angiotensinogen (AGT) for refractory hypertension and 5’-aminolevulinate synthase 1 (ALAS1) for acute hepatic porphyria (AHP), respectively. About CTX211 CTX211 is an allogeneic, gene-edited, stem cell-derived investigational therapy for the treatment of type 1 diabetes (T1D), which incorporates gene edits that aim to make cells hypoimmune and enhance cell fitness. This immune-evasive cell replacement therapy is designed to enable patients to produce their own insulin in response to glucose. A Phase 1 clinical trial for CTX211 for the treatment of T1D is ongoing. About CRISPR Therapeutics Since its inception over a decade ago, CRISPR Therapeutics has transformed from a research-stage company advancing programs in the field of gene editing, to a company that recently celebrated the historic approval of the first-ever CRISPR-based therapy and has a diverse portfolio of product candidates across a broad range of disease areas including hemoglobinopathies, oncology, regenerative medicine, cardiovascular, autoimmune, and rare diseases. CRISPR Therapeutics advanced the first-ever CRISPR/Cas9 gene-edited therapy into the clinic in 2018 to investigate the treatment of sickle cell disease or transfusion-dependent beta thalassemia, and beginning in late 2023, CASGEVY (exagamglogene autotemcel [exa-cel]) was approved in some countries to treat eligible patients with either of those conditions. The Nobel Prize-winning CRISPR science has revolutionized biomedical research and represents a powerful, clinically validated approach with the potential to create a new class of potentially transformative medicines. To accelerate and expand its efforts, CRISPR Therapeutics has established strategic partnerships with leading companies including Bayer and Vertex Pharmaceuticals. CRISPR Therapeutics AG is headquartered in Zug, Switzerland, with its wholly-owned U.S. subsidiary, CRISPR Therapeutics, Inc., and R&D operations based in Boston, Massachusetts and San Francisco, California, and business offices in London, United Kingdom.
