Abstract number: S236
The second oral presentation includes longer follow-up from patients enrolled in the dose escalation portion of the ongoing CaMMouflage phase 1 clinical trial evaluating CB-011 in patients with relapsed or refractory multiple myeloma. Details of the CaMMouflage phase 1 presentation are as follows:
Title: CB-011, an allogeneic anti-BCMA CAR-T cell therapy with immune cloaking, for patients with relapsed/refractory multiple myeloma (CaMMouflage phase 1 trial)

About vispacabtagene regedleucel
Vispacabtagene regedleucel (vispa-cel; formerly known as CB-010) is an allogeneic anti-CD19 CAR-T cell therapy evaluated in patients with relapsed or refractory B cell non-Hodgkin lymphoma (r/r B-NHL). To Caribou’s knowledge, vispa-cel is the first allogeneic CAR-T cell therapy in the clinic with a PD-1 knockout, a genome-editing strategy designed to enhance CAR-T cell activity by limiting premature CAR-T cell exhaustion. The FDA granted vispa-cel Regenerative Medicine Advanced Therapy (RMAT), Fast Track, and Orphan Drug designations for B-NHL.
About the ANTLER phase 1 clinical trial
The ANTLER phase 1 clinical trial evaluated vispa-cel in adult patients with r/r B-NHL in a multicenter, open-label trial. As of a September 2, 2025, data cutoff date, 84 patients were treated in the trial. Using a 3+3 enrollment strategy, safety and efficacy were assessed in 16 patients in dose escalation who received a single dose of 40x106, 80x106, or 120x106 CAR-T cells preceded by a lymphodepletion (LD) regimen of cyclophosphamide at 60 mg/kg/day for 2 days followed by fludarabine at 25 mg/m2/day for 5 days. Eighty million (80x106) CAR-T cells was selected as the recommended phase 2 dose (RP2D). Sixty-three second-line large B cell lymphoma (2L LBCL) patients received a single dose of vispa-cel during dose expansion. Five patients were enrolled in a cohort of third-line or later LBCL patients with prior exposure to CD19-targeted therapy. Additional information on the ANTLER trial (NCT04637763) can be found at www.clinicaltrials.gov.
About CB-011
CB-011 is an allogeneic anti-BCMA CAR-T cell therapy being evaluated in patients with relapsed or refractory multiple myeloma (r/r MM). To Caribou’s knowledge, CB-011 is the first allogeneic CAR-T cell therapy in the clinic that is engineered to enable activity through an immune cloaking strategy with a B2M knockout and insertion of a B2M–HLA-E fusion protein to blunt immune-mediated rejection. The FDA granted CB-011 RMAT, Fast Track, and Orphan Drug designations for r/r MM.
About the CaMMouflage phase 1 clinical trial
The CaMMouflage clinical trial is a multicenter, open-label phase 1 trial evaluating CB-011 in adults with r/r MM who have been treated with three or more prior lines of therapy. Using a 3+3 dose escalation design, safety and efficacy of CB-011 were evaluated in 48 patients at multiple dose levels and two different lymphodepletion (LD) regimens. Thirteen patients were treated with a single dose of CB-011 (50x106 [N=3], 150x106 [N=7], and 450x106 [N=3] CAR-T cells) with an LD regimen of 300 mg/m2 cyclophosphamide and 30 mg/m2 fludarabine daily for 3 days, and 35 patients were treated with a single dose of CB-011 (150x106 [N=6], 300x106 [N=13], 450x106 [N=13], and 800x106 [N=3] CAR-T cells) with an LD regimen of 500 mg/m2 cyclophosphamide and 30 mg/m2 fludarabine daily for 3 days. The dose expansion portion of the trial is evaluating safety and efficacy of CB-011 at 450x106 CAR-T cells with the selected LD of 500 mg/m2 cyclophosphamide and 30 mg/m2 fludarabine daily for three days. Additional information on the CaMMouflage trial (NCT05722418) can be found at www.clinicaltrials.gov.
