Item 7.01. |
Regulation FD Disclosure. |
On November 4, 2020, CRISPR Therapeutics AG, or the Company, issued a press release announcing that a new expanded data set from two ongoing Phase 1/2 clinical trials of the investigational CRISPR/Cas9 gene-editing therapy CTX001TM in severe hemoglobinopathies has been accepted for an oral presentation during the Plenary Scientific Session at the 62nd American Society of Hematology (ASH) Meeting and Exposition, which will take place virtually from December 5-8, 2020. A copy of the press release is attached hereto as Exhibit 99.1.
The information in this Item 7.01 of Form 8-K, including the accompanying Exhibit 99.1, shall not be deemed “filed” for purposes of Section 18 of the Securities Exchange Act of 1934 (the “Exchange Act”), or otherwise subject to the liability of such section, nor shall such information be deemed incorporated by reference in any filing under the Securities Act of 1933 or the Exchange Act, regardless of the general incorporation language of such filing, except as shall be expressly set forth by specific reference in such filing.

Item 8.01. |
Other Events |
On November 4, 2020, ASH published online an abstract submitted by the Company and its partner, Vertex Pharmaceuticals Incorporated, that includes new clinical data from two ongoing Phase 1/2 open-label clinical trials of CTX001 in transfusion-dependent beta thalassemia, or TDT, (CLIMB THAL-111) and severe sickle cell disease, or SCD, (CLIMB SCD-121). Available safety and efficacy results from all patients with at least three months of follow-up from both studies as of July 2020 are presented.
Data are presented for five patients with TDT. These patients had a red blood cell transfusion history ranging from 23.5 to 61 units per year. CTX001 post-infusion follow-up data are presented through months 15, 6, 4, 4, and 3, respectively. In the patients with TDT, median neutrophil engraftment occurred on Day 32 (range: 27 to 36) and median platelet engraftment occurred on Day 37 (range: 34 to 52). All patients demonstrated increases in total hemoglobin, or Hb, and fetal hemoglobin, or HbF, over time. Patients with TDT ceased receiving packed red blood cell, or pRBC, transfusions soon after CTX001 infusion, with the last pRBC transfusion occurring between 0.9 and 1.9 months after CTX001 infusion. See Figure A below.
Data are presented for two patients with SCD. These patients had 7 vaso-occlusive crises, or VOCs, per year and 7.5 VOCs per year, respectively, annualized over two years prior to consent. CTX001 post-infusion follow-up data are presented through months 12 and 3, respectively. In the patients with SCD, neutrophil engraftment occurred on Day 30 and Day 22 and platelet engraftment occurred on Day 30 and Day 33, respectively. All patients demonstrated increases in total Hb and HbF over time. Patients with SCD have had no VOCs since CTX001 infusion. See Figure B below.
In all seven patients, the safety profile after CTX001 infusion was generally consistent with busulfan myeloablation. Four serious adverse events, or SAEs, related or possibly related to CTX001 were reported in one patient with TDT: headache, haemophagocytic lymphohistiocytosis, or HLH, acute respiratory distress syndrome, and idiopathic pneumonia syndrome. All four of these SAEs occurred in the context of HLH and were either resolved or clinically improving at the time of this analysis. No other CTX001-related SAEs were reported in the other patients with TDT or in any patients with SCD.
These trials are ongoing and patients will be followed for approximately two years following infusion.

Exhibit 99.1
CRISPR/Cas9 Gene-Editing Therapy CTX001™ for Severe Hemoglobinopathies Accepted for Plenary Presentation at the 62nd American Society of Hematology (ASH) Meeting and Exposition
ZUG, Switzerland and CAMBRIDGE, Mass. and BOSTON, November 4, 2020 -- CRISPR Therapeutics (Nasdaq: CRSP) and Vertex Pharmaceuticals Incorporated (Nasdaq: VRTX) today announced data in seven patients from two ongoing Phase 1/2 clinical trials of the investigational CRISPR/Cas9 gene-editing therapy CTX001 in severe hemoglobinopathies has been accepted for an oral presentation during the Plenary Scientific Session at the annual ASH Meeting and Exposition, which will take place virtually from December 5-8, 2020. Haydar Frangoul, M.D., Medical Director of Pediatric Hematology and Oncology at Sarah Cannon Research Institute, HCA Healthcare’s TriStar Centennial Medical Center, will deliver the presentation on behalf of all the authors on December 6, 2020.
An abstract posted online today includes data from five patients with three months to 15 months of follow-up after CTX001 infusion in the ongoing Phase 1/2 CLIMB-111 trial in transfusion-dependent beta thalassemia (TDT) and data from two patients with three months and 12 months of follow-up in the ongoing Phase 1/2 CLIMB-121 trial in severe sickle cell disease (SCD). Additional data will be presented at ASH, including longer-duration follow-up data for the patients included in the abstract and data for additional patients with greater than three months of follow-up.
CTX001 is being investigated in these two ongoing clinical trials as a potential one-time curative therapy for patients suffering from TDT and severe SCD.
The accepted abstract is now available on the ASH conference website.
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 engineered 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 TDT patients and reduce painful and debilitating sickle crises for SCD patients.
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). 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.
CTX001 is being developed under a co-development and co-commercialization agreement between CRISPR Therapeutics and Vertex. Among gene-editing approaches being investigated/evaluated for TDT and SCD, CTX001 is the furthest advanced in clinical development.
About CLIMB-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-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.
About the Gene-Editing Process in These Trials
Patients who enroll in these trials will have their own hematopoietic stem and progenitor cells collected from peripheral blood. The patient’s cells will be edited using the CRISPR/Cas9 technology. The edited cells, CTX001, will then be infused back into the patient as part of a stem cell transplant, a process which involves, among other things, a patient being treated with myeloablative busulfan conditioning. Patients undergoing stem cell transplants may also encounter side effects (ranging from mild to severe) that are unrelated to the administration of CTX001. Patients will initially be monitored to determine when the edited cells begin to produce mature blood cells, a process known as engraftment. After engraftment, patients will continue to be monitored to track the impact of CTX001 on multiple measures of disease and for safety.
About the CRISPR-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. CTX001 represents the first potential treatment to emerge from the joint research program. CRISPR Therapeutics and Vertex will jointly develop and commercialize CTX001 and equally share all research and development costs and profits worldwide.
