Overview
Tozaro develops Smart Polymers, a novel class of synthetic affinity ligands designed to improve viral vector purification and analytics for cell and gene therapies. Their computational chemistry and machine learning platform enables cost-effective manufacturing of lentiviral vectors for CAR-T treatments and AAV vectors, with applications in downstream processing and quality control. The company's technology uses over 600 chemical monomers to create custom affinity solutions that outperform traditional biological reagents, helping pharmaceutical manufacturers reduce per-dose costs while improving yield and recovery rates.
Frequently asked questions
- What specific viral vectors does Tozaro support?
- Tozaro's lead program focuses on affinity purification of lentiviral vectors for CAR-T cell therapy manufacturing. Their second program addresses AAV (adeno-associated virus) affinity purification across multiple capsid serotypes. The company is also developing smart polymers that bind the VSV-G membrane protein of lentivirus with gentle release conditions.
- How does Tozaro's technology differ from conventional purification methods?
- Tozaro's Smart Polymers use computational chemistry and machine learning to design synthetic affinity ligands with access to over 600 chemical monomers, compared to the 20 amino acids available in traditional biological reagents. This expanded design space enables higher specificity, gentler capture and release of viral vectors, improved host cell protein removal, and better preservation of vector quality during purification.
- What are the manufacturing and supply chain advantages?
- Smart Polymers are chemically manufactured rather than biologically derived, enabling large batch sizes, rapid scale-up, and consistent manufacturing. They are free of animal-derived components, reducing contamination risks. The platform provides reproducible, scalable affinity solutions with improved supply chain reliability compared to biological reagents.
