"At Caribou, we are redefining what patients and physicians should expect from allogeneic CAR-T cell therapy," said Rachel Haurwitz, PhD, president and CEO of Caribou. "The data presented at EHA (Free EHA Whitepaper) 2026 continue to demonstrate that a single dose of vispa-cel can produce durable responses on par with autologous CAR-T cell therapies in patients with second-line large B cell lymphoma, and a single dose of CB-011 results in deep, durable responses in high-risk patients with relapsed or refractory multiple myeloma. With our off-the-shelf approach, these programs have the potential to dramatically expand CAR-T cell therapy access for patients."

Clinical highlights

Vispacabtagene regedleucel (vispa-cel; formerly CB-010), a clinical-stage allogeneic anti-CD19 CAR-T cell therapy for patients with relapsed or refractory B cell non-Hodgkin lymphoma
•In June, long-term follow-up clinical data from the ANTLER phase 1 clinical trial were presented at the 2026 European Hematology Association (EHA) (Free EHA Whitepaper) Annual Meeting. Data presented reinforced vispa-cel is the only single-dose, off-the-shelf therapy to demonstrate deep and durable responses on par with autologous CAR-T cell therapies in second-line (2L) large B cell lymphoma (LBCL). Efficacy and safety data in 2L LBCL patients who had received a single dose of 80 million optimized vispa-cel CAR-T cells (N=27) included:
◦82% overall response rate (ORR)
◦67% complete response (CR) rate
◦17.1-month median progression-free survival (PFS)
◦Generally well-tolerated safety profile
•Optimized vispa-cel is defined as cells from a donor younger than 30 years old with at least two matched human leukocyte antigen (HLA) alleles between patient and donor. The 27-patient subgroup best represents the treatment regimen and patient population for Caribou’s planned ANTLER-3 pivotal phase 3 clinical trial.
•Caribou previously reached alignment with the U.S. Food and Drug Administration (FDA) regarding its planned ANTLER-3 pivotal phase 3 clinical trial design, which is expected to be a randomized, controlled clinical trial enrolling approximately 250 CD19-naïve 2L LBCL patients who are not eligible for transplant and not candidates or not eligible for autologous CAR-T cell therapy based on access challenges or medical criteria, including the urgent need for therapy.

CB-011, a clinical-stage allogeneic anti-BCMA CAR-T cell therapy for patients with relapsed or refractory multiple myeloma (r/r MM)
•In June, longer follow-up dose escalation clinical data from the CaMMouflage phase 1 clinical trial were presented at the 2026 EHA (Free EHA Whitepaper) Annual Meeting. Data continue to demonstrate that CB-011 drives deep, durable responses after a single dose. Twelve BCMA-naïve patients were treated with the recommended dose for expansion (RDE) of 450 million CB-011 CAR-T cells after lymphodepletion. Efficacy and safety data for this cohort included:
◦92% ORR
◦83% CR or stringent CR (≥CR) rate
◦91% minimal residual disease (MRD) negativity in 10/11 evaluable patients
◦50% of patients in ≥CR at 15 months
◦Manageable safety profile
•Caribou also reported a patient case study of a 71-year-old male with r/r MM who received eight prior lines of therapy, including ciltacabtagene autoleucel, an approved autologous CAR-T cell therapy. Before entering CaMMouflage, the patient never achieved a CR following any of his post-front-line therapies. After receiving a single dose of 450 million CB-011 CAR-T cells (the RDE), the patient achieved a CR at day 28 that was maintained at month 3 and remained ongoing as of the May 26, 2026, efficacy data cutoff date.
•Caribou is enrolling BCMA-naïve and prior BCMA therapy-exposed r/r MM patients in the dose expansion portion of the CaMMouflage trial. In the second half of 2026, Caribou expects to report initial safety and efficacy from dose expansion on more than 15 patients with a minimum of three months follow up, as well as longer follow-up data on the 12-patient, BCMA-naïve RDE cohort from dose escalation.
Second quarter 2026 financial results
Licensing and other third-party revenue: Revenue from licensing and other third-party agreements was $1.5 million for the three months ended June 30, 2026, compared to $2.7 million for the same period in 2025.

R&D expenses: Research and development expenses were $18.9 million for the three months ended June 30, 2026, compared to $27.7 million for the same period in 2025. The decrease was primarily related to decreased external contract manufacturing organization and contract research organization activities; expenses related to the reduction in workforce and strategic pipeline prioritization announced in April 2025; facilities and allocated expenses; and expenses related to licenses, sublicensing revenue, and milestones.

G&A expenses: General and administrative expenses were $7.9 million for the three months ended June 30, 2026, compared to $10.4 million for the same period in 2025. The decrease was primarily due to personnel-related expenses related to the reduction in workforce and strategic pipeline prioritization announced in April 2025; lower legal expenses; other service-related expenses; and other facilities and allocated expenses.

GAAP net loss and net loss per share, basic and diluted: Caribou reported a GAAP net loss of $24.3 million, or $0.24 per share, basic and diluted, for the three months ended June 30, 2026, compared to $54.1 million, or $0.58 per share, basic and diluted, for the same period in 2025, which included $21.3 million in non-cash impairment charges.

Cash, cash equivalents, and marketable securities: Caribou had $113.8 million in cash, cash equivalents, and marketable securities as of June 30, 2026, compared to $142.8 million as of December 31, 2025. Caribou now expects that its cash, cash equivalents, and marketable securities will be sufficient to fund its current operating plan, including dose expansion for CB-011 and certain start-up activities for its planned ANTLER-3 pivotal phase 3 clinical trial for vispa-cel, to the end of 2027. Caribou is exploring multiple options to fully fund its planned ANTLER-3 clinical 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. Eighty-five 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 40, 80, or 120 million 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. Sixty-three second-line large B cell lymphoma (2L LBCL) patients received a single dose of vispa-cel during dose expansion. Eighty million CAR-T cells was selected as the recommended phase 2 dose (RP2D). Six 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-peptide 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. Thirty-five patients were treated with a single dose of CB-011 (150 million [N=6], 300 million [N=13], 450 million [N=13], and 800 million [N=3] CAR-T cells) with an LD regimen of 500 mg/m2 cyclophosphamide and 30 mg/m2 fludarabine daily for three days. The dose expansion portion of the trial is evaluating safety and efficacy of 450 million CB-011 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.
