- Caribou reported encouraging data from the dose escalation portion of the ANTLER Phase 1 trial evaluating CB-010 in 16 patients with relapsed or refractory B cell non-Hodgkin lymphoma (r/r B-NHL). Dose escalation data showed CB-010’s response rates and safety profile have the potential to rival those of the approved autologous CAR-T cell therapies.
- In the ongoing ANTLER Phase 1 trial, Caribou is enrolling second-line relapsed or refractory large B cell lymphoma (r/r LBCL) patients in the dose expansion portion. Currently, 22 U.S. and 3 international sites are active, with additional site activation underway.
- Caribou provided a regulatory update based on feedback from the U.S. Food and Drug Administration (FDA) following a Type B clinical meeting. The company received the FDA’s feedback on a Phase 3 randomized pivotal trial for CB-010 in second-line r/r LBCL stating that Caribou’s proposed comparator arm of platinum-based immunochemotherapy followed by high dose chemotherapy (HDCT) and autologous stem cell transplantation (ASCT) is acceptable.
- To Caribou’s knowledge, CB-010 is the first anti-CD19 allogeneic CAR-T cell therapy to be evaluated in the second-line LBCL setting and it has been granted Regenerative Medicine Advanced Therapy (RMAT), Fast Track, and Orphan Drug designations by the FDA for specific indications.
“My enthusiasm for the potential of off-the-shelf cell therapies combined with the encouraging CB-010 dose escalation data prompted me to establish Westmead Hospital as the first international site for the ANTLER trial,” said Kenneth Micklethwaite, MD, clinical associate professor at the University of Sydney and hematology staff specialist at the Westmead Hospital. “I look forward to participating in the planned pivotal trial as patients in the second-line setting have an urgent need for treatment given the limitations of current treatment options."
CB-011, an allogeneic anti-BMCA CAR-T cell therapy for multiple myeloma
- Caribou initiated the CaMMouflage Phase 1 trial evaluating CB-011 in patients with relapsed or refractory multiple myeloma (r/r MM).
- CB-011 was granted Fast Track and Orphan Drug designation by the FDA, which are designed to expedite the development and review processes for promising therapeutic candidates that may fill an unmet medical need.
- CaMMouflage trial enrollment has concluded for dose level 1 (50x106 CAR-T cells, N=3) and dose level 2 (150x106 CAR-T cells, N=3) without any dose-limiting toxicities (DLTs), and the trial is enrolling patients at dose level 3 (450x106 CAR-T cells).
CB-012, an allogeneic anti-CLL-1 CAR-T cell therapy for acute myeloid leukemia
- The investigational new drug (IND) application for CB-012 was cleared by the FDA for evaluation in relapsed or refractory acute myeloid leukemia (r/r AML).

About CB-010
CB-010 is the lead product candidate from Caribou’s allogeneic CAR-T cell therapy platform and is being evaluated in patients with relapsed or refractory B cell non-Hodgkin lymphoma (r/r B-NHL). In the ongoing ANTLER Phase 1 trial, Caribou is enrolling second-line patients with large B cell lymphoma (LBCL) comprised of different subtypes of aggressive r/r B-NHL (DLBCL NOS, PMBCL, HGBL, tFL, and tMZL). CB-010 is an allogeneic anti-CD19 CAR-T cell therapy engineered using Cas9 CRISPR hybrid RNA-DNA (chRDNA) genome-editing technology. To Caribou’s knowledge, CB-010 is the first allogeneic CAR-T cell therapy in the clinic with a PD-1 knockout, a genome-editing strategy designed to improve antitumor activity by limiting premature CAR-T cell exhaustion. To Caribou’s knowledge, CB-010 is the first anti-CD19 allogeneic CAR-T cell therapy to be evaluated in the second-line LBCL setting and it has been granted Regenerative Medicine Advanced Therapy (RMAT), Fast Track, and Orphan Drug designations by the FDA for specific indications. Additional information on the ANTLER trial (NCT04637763) can be found at clinicaltrials.gov.
About CB-011
CB-011 is a 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 genome-editing technology. To Caribou’s knowledge, CB-011 is the first allogeneic CAR-T cell therapy in the clinic 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. CB-011 has been granted Fast Track and orphan drug designations by the FDA. Additional information on the CaMMouflage trial (NCT05722418) can be found at clinicaltrials.gov.
About CB-012
CB-012 is a product candidate from Caribou’s allogeneic CAR-T cell therapy platform and will be evaluated in the AMpLify Phase 1 clinical trial in patients with relapsed or refractory acute myeloid leukemia (r/r AML). CB-012 is an anti-CLL-1 CAR-T cell therapy engineered with five genome edits, enabled by Caribou’s patented next-generation CRISPR technology platform, which uses Cas12a chRDNA genome editing to significantly improve the specificity of genome edits. To Caribou’s knowledge, CB-012 is the first allogeneic CAR-T cell therapy with both checkpoint disruption, through a PD-1 knockout, and immune cloaking, through a B2M knockout and B2M–HLA-E fusion protein insertion; both armoring strategies are designed to improve antitumor activity. Additional information on the AMpLify trial (NCT06128044) 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 are capable of editing 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.
