ZUG, Switzerland and CAMBRIDGE, Mass., Oct. 21, 2020 (GLOBE NEWSWIRE) -- CRISPR Therapeutics (Nasdaq: CRSP), a biopharmaceutical company focused on creating transformative gene-based medicines for serious diseases, today announced positive top-line results from the Company’s ongoing Phase 1 CARBON trial evaluating the safety and efficacy of CTX110, its wholly-owned allogeneic CAR-T cell therapy targeting CD19+ B-cell malignancies.

“We are highly encouraged by today’s data, which demonstrate the promise of allogeneic therapies in treating hematological malignancies,” said Samarth Kulkarni, Ph.D., Chief Executive Officer of CRISPR Therapeutics. “Over time, we believe CRISPR-edited allogeneic CAR-T has the potential to leapfrog autologous CAR-T and benefit much broader patient populations. We continue to enroll patients and look forward to additional data read-outs for this program as well as our other allogeneic CAR-T programs, CTX120 and CTX130, next year. We are grateful to the patients and investigators who have made this important research possible.”

"From this early data read-out, CTX110 has shown dose-dependent efficacy and response rates that are comparable to the early autologous CAR-T trials. Furthermore, CTX110 had an acceptable safety profile, which could make CAR-Ts more widely accessible,” said Joseph McGuirk, D.O., Professor of Medicine and Division Director of Hematologic Malignancies and Cellular Therapeutics at the University of Kansas Medical Center and investigator in the Phase 1 CARBON trial of CTX110. “While longer follow-up is required, these early data support the potential for CTX110 to become an effective off-the-shelf CAR-T therapy for patients with relapsed or refractory B-cell malignancies.”

CARBON Trial Overview
The Phase 1 CARBON trial is an open-label, multicenter study evaluating the safety and efficacy of CTX110 in adult patients with relapsed or refractory non-Hodgkin lymphoma, who have received at least two prior lines of therapy. As of the September 28, 2020, data cutoff, 12 patients were enrolled and infused with CTX110. Data are reported for the 11 patients who had at least completed their one-month assessment as of the data cutoff date.
