Future Outlook

Cartesian Therapeutics anticipates initiating a Phase 3 trial for Descartes-08 in myasthenia gravis in the first half of 2025 and expects a data readout from its Phase 2 trial in systemic lupus erythematosus in the second half of 2025. The company also plans to commence a Phase 2 basket trial in pediatric patients with select autoimmune diseases.

Management Comments

• Carsten Brunn, Ph.D., President and Chief Executive Officer of Cartesian, stated that the company is entering the new year with strong momentum and believes it is well-positioned to continue to make meaningful progress advancing its pipeline in 2025.
• Dr. Brunn noted that updated Phase 2b results continue to support the potential for Descartes-08 to provide deep and durable improvements for patients with MG in the convenient outpatient setting without the need for preconditioning chemotherapy.

Industry Context

Cartesian Therapeutics is operating in the competitive field of cell therapy, specifically targeting autoimmune diseases. The company's mRNA CAR-T approach aims to offer advantages over traditional DNA-based CAR-T therapies, such as avoiding preconditioning chemotherapy and enabling outpatient administration.

Comparison to Industry Standards

• The company's approach of using mRNA CAR-T therapy is differentiated from traditional DNA-based CAR-T therapies like Novartis' Kymriah and Gilead's Yescarta, which are primarily used in oncology and require preconditioning chemotherapy.
• Cartesian's focus on autoimmune diseases sets it apart from many CAR-T companies that are primarily focused on cancer.
• The company's goal of outpatient administration aligns with the industry trend towards more convenient and accessible therapies.
• The observed MG-ADL reduction of 5.5 points at Month 4 in the Phase 2b trial suggests a clinically meaningful benefit, which is comparable to or better than some existing treatments for myasthenia gravis.

Stakeholder Impact

• Shareholders: Potential for increased value through successful clinical trials and product development.
• Patients: Potential for new and improved treatment options for autoimmune diseases.
• Employees: Continued employment and growth opportunities within the company.
• Suppliers: Potential for increased business through manufacturing and supply agreements.
• Creditors: Increased confidence in the company's ability to meet its financial obligations.

Next Steps

• Commence Phase 3 AURORA clinical trial of Descartes-08 in myasthenia gravis in 1H 2025.
• Continue enrollment in Phase 2 open-label trial evaluating Descartes-08 in SLE.
• Commence Phase 2 basket trial of Descartes-08 in pediatric patients with select autoimmune diseases in 2025.
• Continue dosing in Phase 1 clinical trial of Descartes-15.
