This investigational therapy has the potential to be a transformative treatment for patients with all insulin-requiring forms of diabetes. Looking ahead, we expect a productive 2022 with continued progress across our portfolio as we enter a new phase of growth for our Company. Given the breadth of our portfolio and our strong capital position, we remain well positioned to advance our pipeline and platform to develop transformative medicines for patients suffering from serious diseases.”

Recent Highlights and Outlook

• Beta Thalassemia and Sickle Cell Disease Programs
  
  • More than 70 patients have been dosed with CTX001 across both trials to date. Target enrollment has been achieved in the ongoing clinical trials for CTX001 in transfusion-dependent beta thalassemia (TDT) and severe sickle cell disease (SCD), with planned regulatory submissions in late 2022.
  • In June 2021, data from 22 patients with at least three months of follow-up after CTX001 infusion were presented at the Annual European Hematology Association Virtual Congress (EHA) and continued to build the profile of a potentially functional cure for patients with TDT and SCD, showing consistent and durable benefit with longer term data from a larger population of patients.
    
  • In April 2021, CRISPR Therapeutics and Vertex announced an amendment to their collaboration for CTX001. In connection with the completion of the transaction in June, Vertex made a $900 million upfront payment to CRISPR Therapeutics.
    
  • In April 2021, CRISPR Therapeutics and Vertex announced that the European Medicines Agency (EMA) granted Priority Medicines (PRIME) designation to CTX001 for the treatment of TDT. CTX001 was granted PRIME designation for the treatment of SCD in 2020.
    
• Immuno-Oncology Programs
  
  • CRISPR Therapeutics has begun dosing patients in the pivotal trial of CTX110, its wholly-owned allogeneic chimeric antigen receptor T cell (CAR-T) investigational therapy targeting CD19+ B-cell malignancies. Enrollment is ongoing and the Company expects to report additional data in 2022. The U.S. Food and Drug Administration (FDA) granted Regenerative Medicine Advanced Therapy (RMAT) designation to CTX110 in November 2021.
    
  • In October 2021, CRISPR Therapeutics announced positive results from its ongoing Phase 1 CARBON trial evaluating the safety and efficacy of CTX110. The data showed early evidence of a dose dependent response to CTX110, with overall response rates (ORR), complete response rates (CR) and durability similar to approved autologous CD19 CAR-T therapies on an intent-to-treat (ITT) basis. A single dose of CTX110 at DL2 and above resulted in a 58% ORR and 38% CR rate in large B-cell lymphoma (LBCL) patients on an ITT basis. The pharmacokinetic data provide a strong rationale that consolidation dosing can improve on an already competitive profile for CTX110. Based on the safety and efficacy profile, the Company has expanded the current trial into a pivotal trial that incorporates consolidation dosing and has begun dosing patients in this pivotal arm. The Company expects to report additional data in 2022.
    
  • In addition to CTX110, CRISPR Therapeutics has ongoing Phase 1 clinical trials assessing safety and efficacy of several dose levels for the following CAR-Ts: (i) CTX120, its wholly-owned allogeneic CAR-T investigational therapy targeting B-cell maturation antigen for the treatment of relapsed or refractory multiple myeloma; and (ii) CTX130, its wholly-owned allogeneic CAR-T investigational therapy targeting CD70 for the treatment of both solid tumors and certain hematologic malignancies. The Company expects to report top-line data in the first half of 2022.
    
  • In May 2021, CRISPR Therapeutics and Nkarta, Inc. announced a strategic partnership to research, develop, and commercialize CRISPR/Cas9 gene-edited cell therapies for cancer. Under the agreement, the companies will co-develop and co-commercialize two CAR-NK cell product candidates, one targeting the CD70 tumor antigen and the other target to be determined. In addition, the companies will bring together their complementary cell therapy engineering and manufacturing capabilities to advance the development of a novel NK+T product candidate harnessing the synergies of the adaptive and innate immune systems.
    
• Regenerative Medicine and In Vivo Programs
  
  • Earlier this month, CRISPR Therapeutics and its partner ViaCyte announced the first patient had been dosed in the Phase 1 clinical trial of VCTX210 for the treatment of T1D. VCTX210 is an investigational, allogeneic, gene-edited, stem cell-derived product developed in collaboration by applying CRISPR Therapeutics’ gene-editing technology to ViaCyte’s proprietary stem cell capabilities for the generation of pancreatic cells designed to evade recognition by the immune system. This immune-evasive cell replacement therapy is designed to enable patients to produce their own insulin.
    
  • In June 2021, CRISPR Therapeutics and Capsida Biotherapeutics, Inc. announced a strategic partnership to research, develop, manufacture and commercialize in vivo gene editing therapies delivered with engineered AAV vectors for the treatment of familial amyotrophic lateral sclerosis (ALS) and Friedreich’s ataxia. Under the agreement, CRISPR Therapeutics will lead research and development of the Friedreich’s ataxia program and perform gene-editing activities for both programs, and Capsida will lead research and development of the ALS program and conduct capsid engineering for both programs.
    
  • The Company continues to make progress with its in vivo approaches for liver gene editing utilizing both viral and non-viral delivery vehicles. The Company expects to move multiple programs utilizing in vivo approaches into the clinic in the next 18 to 24 months.
    
• Other Corporate Matters
  
  • Under the June 2019 collaboration agreement with Vertex to discover and develop gene editing therapies for the treatment of Duchenne Muscular Dystrophy (DMD) and Myotonic Dystrophy Type 1 (DM1), CRISPR Therapeutics received a payment of $12.5 million from Vertex related to the achievement of a research milestone in the DM1 program.

About CTX001
CTX001 is an investigational, autologous, ex vivo CRISPR/Cas9 gene-edited therapy that is being evaluated for patients suffering from TDT or severe SCD, in which a patient’s hematopoietic stem cells are edited to produce high levels of fetal hemoglobin (HbF; hemoglobin F) in red blood cells. HbF is a form of the oxygen-carrying hemoglobin that is naturally present at birth, which then switches to the adult form of hemoglobin. The elevation of HbF by CTX001 has the potential to alleviate or eliminate transfusion requirements for patients with TDT and reduce or eliminate painful and debilitating sickle crises for patients with SCD. Earlier results from these ongoing trials were published as a Brief Report in The New England Journal of Medicine in January of 2021.

Based on progress in this program to date, CTX001 has been granted Regenerative Medicine Advanced Therapy (RMAT), Fast Track, Orphan Drug, and Rare Pediatric Disease designations from the U.S. Food and Drug Administration (FDA) for both TDT and SCD. CTX001 has also been granted Orphan Drug Designation from the European Commission, as well as Priority Medicines (PRIME) designation from the European Medicines Agency (EMA), for both TDT and SCD.

Among gene-editing approaches being investigated/evaluated for TDT and SCD, CTX001 is the furthest advanced in clinical development.
