-- CaMMouflage Phase 1 trial for CB-011 enrolling patients with r/r MM at dose level 1 --
BERKELEY, Calif., April 04, 2023 (GLOBE NEWSWIRE) -- Caribou Biosciences, Inc. (Nasdaq: CRBU), a leading clinical-stage CRISPR genome-editing biopharmaceutical company, today announced that the U.S. Food and Drug Administration (FDA) has granted Fast Track designation to CB-011, which is being developed for relapsed or refractory multiple myeloma (r/r MM). CB-011 is being evaluated in the company’s ongoing CaMMouflage Phase 1 clinical trial in patients with r/r MM.
“Fast Track designation for CB-011 allows us instrumental interactions with the FDA as we progress our clinical development and regulatory plans for CB-011. This designation could not be more timely as we recently dosed our first patient in the CaMMouflage Phase 1 trial,” said Syed Rizvi, MD, Caribou’s chief medical officer. “Our goal is to develop CB-011 as a readily available off-the-shelf treatment option for patients with relapsed or refractory multiple myeloma to overcome the need for apheresis or bridging therapy, variable quality and long manufacturing timelines, manufacturing failures, or the inability to bear the burden of treatments that require frequent dosing over several months.”
Fast Track designation is designed to expedite the development and review processes for promising therapeutic candidates that may fill an unmet medical need. Clinical programs with Fast Track designation may benefit from early and frequent communication with the FDA throughout the regulatory review process and may also be eligible for Accelerated Approval and Priority Review if relevant criteria are met.
About CB-011
CB-011 is the second product candidate from Caribou’s allogeneic CAR-T cell therapy platform and is being evaluated in patients with relapsed or refractory multiple myeloma (r/r MM) in the CaMMouflage Phase 1 trial. CB-011 is an allogeneic anti-BCMA CAR-T cell therapy engineered using Cas12a chRDNA technology. CB-011 is the first allogeneic CAR-T cell therapy in the clinic, to Caribou’s knowledge, that is engineered to improve antitumor activity through an immune cloaking strategy with a B2M knockout and insertion of a B2M–HLA-E fusion protein to blunt immune-mediated rejection. Additional information on the CaMMouflage trial (NCT05722418) can be found at clinicaltrials.gov.
About Caribou’s Novel Next-Generation CRISPR Platform
CRISPR genome editing uses easily designed, modular biological tools to make DNA changes in living cells. There are two basic components of Class 2 CRISPR systems: the nuclease protein that cuts DNA and the RNA molecule(s) that guide the nuclease to generate a site-specific, double-stranded break, leading to an edit at the targeted genomic site. CRISPR systems have exhibited editing at unintended genomic sites, known as off-target editing, which may lead to harmful effects on cellular function and phenotype. In response to this challenge, Caribou has developed CRISPR hybrid RNA-DNA guides (chRDNAs; pronounced “chardonnays”) that direct substantially more precise genome editing compared to all-RNA guides. Caribou is deploying the power of its Cas12a chRDNA technology to carry out high efficiency multiple edits, including multiplex gene insertions, to develop CRISPR-edited therapies.
