Develops mRNA-engineered cell therapies for autoimmune diseases, with Descartes-08 as the lead program in myasthenia gravis and myositis. Revenue is not from approved products yet; the business depends on clinical results, regulatory approval, and manufacturing execution at its Frederick facility.
Develops mRNA-engineered cell therapies for autoimmune diseases, with one operating segment tied to research and development after the Selecta merger. Descartes-08 is the lead autologous anti-BCMA mRNA CAR-T candidate, prioritized in myasthenia gravis and myositis programs.
Operations are concentrated in the United States. Clinical manufacturing is anchored at a wholly owned cGMP facility in Frederick, Maryland, which supports current trials and could transition toward commercial supply if a candidate is approved.
The model is development-stage rather than product-sales-driven. Programs depend on clinical trial execution, regulatory approval, patient-specific autologous manufacturing, and future reimbursement if any therapy reaches market.
