ZUG, Switzerland and CAMBRIDGE, Mass., April 27, 2021 (GLOBE NEWSWIRE) -- CRISPR Therapeutics (Nasdaq: CRSP), a biopharmaceutical company focused on creating transformative gene-based medicines for serious diseases, today reported financial results for the first quarter ended March 31, 2021.

“We continue to make progress across our hemoglobinopathies and immuno-oncology programs on the clinical front, and expect to disclose data on multiple programs in 2021,” said Samarth Kulkarni, Ph.D., Chief Executive Officer of CRISPR Therapeutics. “Our revised agreement with Vertex for CTX001 streamlines operations and allows us to further invest in innovation to build upon the remarkable results we have seen with the program thus far. In addition, we are continuing to execute on our earlier stage pipeline and look forward to bringing our regenerative medicine and in vivo programs to the clinic.”

Recent Highlights and Outlook

• Beta Thalassemia and Sickle Cell Disease
  
  • The European Medicines Agency granted Priority Medicines (PRIME) designation to CTX001™, an investigational, autologous, ex vivo CRISPR/Cas9 gene-edited therapy for the treatment of transfusion-dependent beta thalassemia (TDT). CTX001 was previously granted PRIME designation for the treatment of sickle cell disease (SCD) in 2020.
  • Enrollment and dosing are ongoing in the clinical trials for CTX001. More than 30 patients have been dosed with CTX001 across both trials to date. Completion of enrollment in both trials is expected in 2021.
• Immuno-Oncology
  
  • The Company expects to report additional data in 2021 from its ongoing Phase 1 CARBON trial assessing the safety and efficacy of several dose levels of CTX110, its wholly-owned allogeneic chimeric antigen receptor T cell (CAR-T) investigational therapy targeting CD19, for the treatment of relapsed or refractory B-cell malignancies.
  • CRISPR Therapeutics’ Phase 1 clinical trial assessing the safety and efficacy of several dose levels of CTX120, its wholly-owned allogeneic CAR-T investigational therapy targeting B-cell maturation antigen for the treatment of relapsed or refractory multiple myeloma, is ongoing. The Company expects to report top-line data from this trial in 2021.
  • CRISPR Therapeutics’ two independent Phase 1 clinical trials assessing the safety and efficacy of several dose levels of CTX130, its wholly-owned allogeneic CAR-T investigational therapy targeting CD70, for the treatment of both solid tumors and certain hematologic malignancies, are ongoing. The Company expects to report top-line data from these trials in 2021. Earlier this month, the Company announced preclinical data from its CAR-T program at the American Association for Cancer Research (AACR) Annual Meeting 2021. The data, presented in an e-poster session entitled, “CD70 knockout: A novel approach to augment CAR-T cell function, found that the generation of CAR-T cells including knockout of the CD70 show improved properties, including potency and persistence over CAR-T cells where the CD70 gene remains intact.”
• Regenerative Medicine
  
  • CRISPR Therapeutics and its partner ViaCyte remain on track to initiate a Phase 1/2 trial of their allogeneic stem cell-derived therapy for the treatment of Type 1 diabetes in 2021. The combination of ViaCyte’s stem cell capabilities and CRISPR’s gene editing capabilities has the potential to enable a beta-cell replacement product that may deliver durable benefit to patients without requiring immune suppression.
• Other Corporate Matters
  
  • Earlier this month, CRISPR Therapeutics and its partner Vertex announced that the companies have amended their collaboration agreement to develop, manufacture and commercialize CTX001. Under the terms of the amended agreement, CRISPR Therapeutics will be responsible for 40% of the program costs and will receive 40% of the profits from future sales of CTX001 worldwide. With this revised agreement, Vertex will deploy the breadth of its established global capabilities and proven experience in development, manufacturing, and commercialization to maximize the potential for CTX001 to transform the lives of tens of thousands of patients in the U.S., Europe and other countries. CRISPR Therapeutics will continue to support the development of CTX001 and invest in further innovation to maximize its potential. The transaction is subject to customary closing conditions and clearances, including clearance under the Hart-Scott Rodino Antitrust Improvements Act.

First Quarter 2021 Financial Results

• Cash Position: Cash, cash equivalents and marketable securities were $1,806.2 million as of March 31, 2021, compared to $1,690.3 million as of December 31, 2020. The increase in cash of $115.9 million was primarily driven by cash from financing activities of $226.0 million, which consists primarily of proceeds received from sales under our “at-the-market” offering in January and early February of 2021 offset by continuing operating expenses.
  
• Revenue: Total collaboration revenue was $0.2 million for the first quarter of 2021 compared to $0.2 million for first quarter of 2020. Collaboration revenue primarily consisted of charges to partners for research activities.
  
• R&D Expenses: R&D expenses were $90.6 million for the first quarter of 2021 compared to $54.2 million for the first quarter of 2020. The increase in expense was driven by development activities supporting the advancement of the hemoglobinopathies program and wholly-owned immuno-oncology programs, as well as increased headcount and supporting facilities related expenses.
  
• G&A Expenses: General and administrative expenses were $24.5 million for the first quarter of 2021 compared to $19.6 million for the first quarter of 2020. The increase in general and administrative expenses for the year was primarily driven by headcount-related expense.
  
• Net Income/Loss: Net loss was $113.2 million for the first quarter of 2021 compared to a net loss of $69.7 million for the first quarter of 2020.

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 transfusion requirements for patients with TDT and reduce painful and debilitating sickle crises for patients with SCD.

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 for both TDT and SCD, as well as Priority Medicines (PRIME) designation from the European Medicines Agency (EMA) for SCD and TDT.

About the CRISPR-Vertex Collaboration
Vertex and CRISPR Therapeutics 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. CTX001 represents the first potential treatment to emerge from the joint research program. Under a recently amended collaboration agreement, Vertex will lead global development and commercialization of CTX001 and split program costs and profits worldwide 60/40 with CRISPR Therapeutics. This amendment is subject to customary closing conditions and clearances, including clearance under the Hart-Scott Rodino Antitrust Improvements Act.

About CLIMB-Thal-111
The ongoing Phase 1/2 open-label trial, CLIMB-Thal-111, is designed to assess the safety and efficacy of a single dose of CTX001 in patients ages 12 to 35 with TDT. The trial will enroll up to 45 patients and follow patients for approximately two years after infusion. Each patient will be asked to participate in a long-term follow-up trial.

About CLIMB-SCD-121
The ongoing Phase 1/2 open-label trial, CLIMB-SCD-121, is designed to assess the safety and efficacy of a single dose of CTX001 in patients ages 12 to 35 with severe SCD. The trial will enroll up to 45 patients and follow patients for approximately two years after infusion. Each patient will be asked to participate in a long-term follow-up trial.
