ZUG, Switzerland and CAMBRIDGE, Mass., April 29, 2019 (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, 2019.

“This past quarter, we began an important new period for CRISPR Therapeutics with the treatment of the first patient in our clinical trial for CTX001 in hemoglobinopathies,” said Samarth Kulkarni, Ph.D., Chief Executive Officer of CRISPR Therapeutics. “This is a significant landmark for the Company and we continue to enroll patients in our trials for both beta thalassemia and sickle cell disease. With the acceptance of our IND and CTA for CTX110, we look forward to the initiation of our clinical trials for our allogeneic CAR-T programs in the near-term and hope to bring other CAR-T programs to the clinic in the next six to twelve months.”

Recent Highlights and Outlook

• Hemoglobinopathies
  
  • Beta thalassemia
    In April 2019, CRISPR Therapeutics and its partner, Vertex, announced that the U.S. Food and Drug Administration (FDA) had granted Fast Track Designation for CTX001, an investigational, autologous, gene-edited hematopoietic stem cell therapy, for the treatment of transfusion-dependent beta thalassemia (TDT). In February 2019, CRISPR and Vertex announced that the first patient had been treated with CTX001 in a Phase 1/2 clinical study of patients with TDT, marking the first company-sponsored use of a CRISPR/Cas9 therapy in a clinical trial. Enrollment in the Phase 1/2 study in patients with TDT is ongoing.
    
  • Sickle Cell Disease
    The companies are also evaluating CTX001 for the treatment of sickle cell disease (SCD) and received Fast Track Designation for CTX001 from the FDA in January 2019 for SCD. The companies announced in February 2019 that the first patient had been enrolled in a Phase 1/2 clinical study of CTX001 in severe SCD in the U.S. and is expected to be infused with CTX001 in mid-2019. Enrollment in the Phase 1/2 study in patients with SCD is ongoing.

• Immuno-Oncology
  
  • CTX110
    Earlier this year, the FDA approved CRISPR Therapeutics’ Investigational New Drug (IND) application for CTX110, its wholly-owned allogeneic CAR-T cell therapy targeting CD19+ malignancies. Additionally, the Company has obtained approval from Health Canada for its Clinical Trial Application (CTA). CRISPR Therapeutics remains on track to initiate a Phase 1/2 trial to assess the safety and efficacy of CTX110 in the first half of 2019 and continues to work closely with various clinical sites to begin the trial. The Company’s proprietary CRISPR-based allogeneic CAR-Ts have the potential to create the next-generation of cell therapies that may have a superior product profile compared to current autologous therapies and allow accessibility to broader patient populations.
    
  • CRISPR Therapeutics continues to advance additional allogeneic CAR-T candidates including: CTX120™, targeting B-cell maturation antigen (BCMA) for the treatment of multiple myeloma; and CTX130™, targeting CD70 for the treatment of solid tumors and hematologic malignancies. Earlier this month, the Company presented preclinical data targeting multiple solid tumor types with anti-CD70 allogeneic CAR-T cells, further demonstrating consistent expression, durability, selectivity and potent cell killing. The Company also presented data targeting CD33 that showed potent preclinical activity against acute myeloid leukemia (AML) cells. These data were presented during poster sessions at the 2019 American Association for Cancer Research (AACR) Annual Meeting.
    
  • CRISPR Therapeutics will present additional data at the upcoming 2019 American Society of Gene and Cell Therapy (ASGCT) Annual Meeting demonstrating the potential of CRISPR/Cas9 allogeneic CAR-T cell candidates for multiple oncology targets. CRISPR/Cas9 allogeneic CAR-T cells show consistently high percent CAR expression, while maintaining durable potency, low exhaustion, and lack of alloreactivity (#841). The Company will also present data evaluating homology-independent CRISPR/Cas9 off-target assessments methods (#134).

• Corporate Development
  
  • The U.S. Patent Office issued four patents to Dr. Emmanuelle Charpentier, together with The Regents of the University of California and University of Vienna (collectively, CVC). Additionally, CVC was recently granted its third patent in Europe. These patents expand CVC’s wide-ranging CRISPR-Cas9 gene-editing patent portfolio.
    
  • Earlier this year, CRISPR Therapeutics announced strategic collaborations with StrideBio, Inc. and ProBioGen. The Company continues to examine new technologies and capabilities in support of existing programs.
    
  • In February, CRISPR Therapeutics proposed to elect John T. Greene and Katherine A. High, M.D. to its Board of Directors at the Company’s upcoming annual general meeting to be held later this year. Together, they will bring significant strategic and operational experience to CRISPR Therapeutics.

First Quarter 2019 Financial Results

• Cash Position: Cash as of March 31, 2019, was $437.5 million, compared to $456.6 million as of December 31, 2018, a decrease of $19.1 million. Cash used in operations drove the decrease, offset by $25.7 million in net cash provided by financing activities during the quarter.
  
• Revenues: Total collaboration revenues were $0.3 million for the first quarter of 2019 compared to $1.4 million for first quarter of 2018. CRISPR’s collaboration revenue is attributable to its research partnerships with Casebia and Vertex. Cost sharing on the Vertex co-development and co-promotion agreement related to hemoglobinopathies is not included in revenue, but instead as an offset to expense in R&D.
  
• R&D Expenses: R&D expenses were $33.8 million for the first quarter of 2019 compared to $19.5 million for the first quarter of 2018. The increase was driven by headcount and services expense supporting the advancement of the hemoglobinopathies program, the broadening of the wholly-owned immuno-oncology portfolio, as well as increased investment in the Company’s CRISPR/Cas9 platform research.
  
• G&A Expenses: General and administrative expenses were $14.9 million for the first quarter of 2019 compared to $8.8 million for the first quarter of 2018. The increase was driven by headcount-related expense and external professional and consulting service expense.
  
• Net Loss: Net loss was $48.4 million for the first quarter of 2019 compared to a loss of $28.3 million for the first quarter of 2018, driven predominantly by increased R&D expense in the quarter.
