BOSTON & ZUG, Switzerland--(BUSINESS WIRE)--Sep 27, 2022--
Vertex Pharmaceuticals Incorporated (Nasdaq: VRTX) and CRISPR Therapeutics (Nasdaq: CRSP) today announced that Vertex has concluded discussions with the U.S. Food and Drug Administration (FDA), and the FDA granted exagamglogene autotemcel (exa-cel) a rolling review for the potential treatment of sickle cell disease (SCD) and transfusion-dependent beta thalassemia (TDT). Vertex will submit its biologics licensing application (BLA) for exa-cel for rolling review, beginning in November 2022 and expects to complete the submission by the end of Q1 2023.
Vertex previously completed discussions with the European Medicines Agency (EMA) and the Medicines and Healthcare products Regulatory Agency (MHRA) on the data required to support those marketing applications and is on track to submit by the end of 2022.
“We are pleased to have concluded our exa-cel pre-submission meetings with regulators and are excited that FDA has granted a rolling review,” said Nia Tatsis Ph.D., Executive Vice President, Chief Regulatory and Quality Officer. “We continue to work with urgency to bring forward the first CRISPR therapy for a genetic disease, and one that holds potential to transform the lives of patients with sickle cell disease or beta thalassemia.”
Based on progress in this program to date, exa-cel has been granted multiple important regulatory designations, including Regenerative Medicine Advanced Therapy (RMAT), Fast Track, Orphan Drug, and Rare Pediatric Disease Designations from the FDA for both SCD and TDT. Exa-cel has also been granted Orphan Drug Designation (ODD) from the European Commission, as well as Priority Medicines (PRIME) designation from the EMA, for both SCD and TDT.
Exa-cel is being investigated in multiple ongoing clinical trials as a potential one-time therapy for patients with either SCD or TDT.
About exagamglogene autotemcel (exa-cel)
Exa-cel, formerly known as CTX001™, is an investigational, autologous, ex vivo CRISPR/Cas9 gene-edited therapy that is being evaluated for patients with TDT or SCD, in which a patient’s own hematopoietic stem cells are edited to produce 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. The elevation of HbF by exa-cel has the potential to alleviate transfusion requirements for patients with TDT and reduce painful and debilitating sickle crises for patients with SCD. Earlier results from these ongoing trials were published in The New England Journal of Medicine in January of 2021 and updated results were shared at the annual European Hematology Association (EHA) Congress in June 2022.
About CLIMB‑111 and CLIMB‑121
The ongoing Phase 1/2/3 open-label trials, CLIMB‑111 and CLIMB‑121, are designed to assess the safety and efficacy of a single dose of exa-cel in patients ages 12 to 35 years with TDT or SCD, respectively. The trials are now closed for enrollment. Patients will be followed for approximately two years after exa-cel infusion. Each patient will be asked to participate in CLIMB‑131, a long-term ‑follow-up trial.
About CLIMB-131
This is a long-term, open-label trial to evaluate the safety and efficacy of exa-cel in patients who received exa-cel in CLIMB‑111, CLIMB‑121, CLIMB‑141 or CLIMB‑151. The trial is designed to follow participants for up to 15 years after exa-cel infusion.
About CLIMB‑141 and CLIMB‑151
The ongoing Phase 3 open-label trials, CLIMB‑141 and CLIMB‑151, are designed to assess the safety and efficacy of a single dose of exa-cel in patients ages 2 to 11 years with TDT or SCD, respectively. The trials are now open for enrollment and currently enrolling patients ages 5 to 11 years of age and will plan to extend to ages 2 to less than 5 years of age at a later date. Each trial will enroll approximately 12 patients. Patients will be followed for approximately two years after infusion. Each patient will be asked to participate in CLIMB-131, 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, exa-cel, will then be infused back into the patient as part of an autologous hematopoietic stem cell transplant (HSCT), a process which involves a patient being treated with myeloablative busulfan conditioning. Patients undergoing HSCT may also encounter side effects (ranging from mild to severe) that are unrelated to the administration of exa-cel. 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 exa-cel on multiple measures of disease and for safety.
About the Vertex and CRISPR Therapeutics 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. Exa-cel 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 exa-cel and splits program costs and profits worldwide 60/40 with CRISPR Therapeutics.
