Updates on the CB-012 trial will be provided as it progresses.

Management Comments

• Rachel Haurwitz, PhD, Caribou's president and chief executive officer, stated that the company enters 2024 with momentum advancing three clinical-stage off-the-shelf CAR-T cell therapy programs.
• She also mentioned the plan to present initial dose expansion data and the RP2D for CB-010 in the second quarter of 2024 and initial dose escalation data for CB-011 by year-end 2024.

Industry Context

This announcement highlights the ongoing progress in the field of allogeneic CAR-T cell therapy, where Caribou is a key player. The company's focus on innovative genome-editing technologies and its clinical trial advancements position it as a significant competitor in the biopharmaceutical space, particularly in the treatment of hematologic malignancies.

Comparison to Industry Standards

• Caribou's CB-010 is positioned as the first anti-CD19 allogeneic CAR-T cell therapy to be evaluated in the second-line LBCL setting, which is a novel approach compared to existing autologous CAR-T therapies like those from Gilead (Yescarta) and Novartis (Kymriah).
• The company's use of CRISPR technology, particularly its chRDNA platform, aims to improve the precision and safety of genome editing, which is a key differentiator from other companies using traditional CRISPR methods.
• The immune cloaking strategy employed in CB-011 and the combination of checkpoint disruption and immune cloaking in CB-012 are innovative approaches that aim to overcome limitations of current CAR-T therapies, potentially offering improved efficacy and reduced rejection rates compared to other allogeneic CAR-T therapies in development by companies like Allogene Therapeutics and CRISPR Therapeutics.
• Caribou's cash runway into Q1 2026 is a positive sign, indicating a strong financial position compared to some smaller biotech companies that may face near-term funding challenges.

Stakeholder Impact

• Shareholders will be encouraged by the positive clinical trial progress and strong cash position.
• Employees will be impacted by the company's growth and continued development of its pipeline.
• Patients with hematologic malignancies may benefit from the development of new treatment options.
• Suppliers and creditors will be impacted by the company's financial performance and operational activities.

Next Steps

• Caribou plans to present initial dose expansion data and the RP2D for CB-010 in Q2 2024.
• The company plans to present initial dose escalation data from the CaMMouflage Phase 1 clinical trial for CB-011 by year-end 2024.
• Caribou will provide updates on dose escalation as the AMpLify Phase 1 clinical trial for CB-012 advances.
• The company will continue enrolling patients in the ANTLER and CaMMouflage trials.
