  • Sales: USD 3.8 billion in 2024, primarily from vaccines; cell therapy delivery (mRNA for CAR T) is a smaller, growing segment.
  • Analysis: BioNTech’s vast revenue overshadows PolyNovo, but its cell therapy delivery is less commercialized, aligning PolyNovo’s T1D efforts with BioNTech’s early-stage innovation.

Summary: Gilead and J&J lead in sales due to established CAR T-cell therapies, while PolyNovo, SQZ, and MaxCyte have lower or no sales in cell therapy delivery. PolyNovo’s T1D application is pre-revenue but shows promise for future growth.

2. Delivery Method Innovation

• PolyNovo:
  • Method: NovoSorb Biodegradable Temporizing Matrix (BTM) creates a neovascularized dermal site for transplanting pancreatic islet cells in T1D patients, replacing liver-based transplantation. Key innovations:
    
    • Supports cell survival (75% cell loss in liver vs. sustained function in NovoSorb for 3 years).
    • Enables in vivo monitoring and biopsy due to subcutaneous placement.
    • Allows topical immunosuppression, reducing systemic side effects.
  • Trial Results: In a proof-of-concept study, three T1D patients post-kidney transplant received islet cells via NovoSorb BTM, with one patient maintaining normal blood sugar (5 mmol/L) for three years without additional cells.
    
  • Analysis: NovoSorb’s subcutaneous delivery is a breakthrough for T1D, addressing liver transplantation’s limitations (cell loss, monitoring challenges). Its biomaterial scaffold is unique compared to infusion-based methods.
• Gilead Sciences:
  • Method: IV infusion of CAR T-cells (Yescarta, Tecartus), optimized for systemic delivery to blood cancers.
  • Innovation: Standardized protocols reduce infusion-related toxicities (e.g., cytokine release syndrome) and improve outpatient delivery.
  • Analysis: Gilead’s method is highly effective for oncology but lacks the precision of localized delivery like NovoSorb’s matrix for T1D.
• Johnson & Johnson:
  • Method: IV infusion for Carvykti, with lymphodepletion to enhance T-cell engraftment.
  • Innovation: Focuses on dosing precision and scalability for multiple myeloma treatment.
  • Analysis: Similar to Gilead, J&J’s delivery is systemic and oncology-focused, less innovative for non-cancer applications like T1D compared to PolyNovo.
• SQZ Biotechnologies:
  • Method: Cell Squeeze® uses microfluidic technology for intracellular delivery of cargos (e.g., antigens) into cells, enabling in situ cell engineering.
  • Innovation: Non-viral, point-of-care delivery reduces manufacturing complexity.
  • Analysis: SQZ’s approach is versatile but ex vivo-focused, whereas PolyNovo’s in vivo scaffold directly supports cell function post-delivery, offering a complementary innovation.
• MaxCyte:
  • Method: Flow Electroporation® for ex vivo cell modification, enabling delivery of genetic material before infusion.
  • Innovation: Scalable, GMP-compliant platform for CAR T and NK cell therapies.
  • Analysis: MaxCyte enhances cell preparation, not direct patient delivery, making PolyNovo’s in vivo matrix more innovative for administration.
• BioNTech:
  • Method: mRNA-loaded nanoparticles for in vivo CAR T-cell generation, bypassing ex vivo processing.
  • Innovation: Reduces manufacturing time and enables targeted immune cell reprogramming.
  • Analysis: BioNTech’s in vivo approach aligns with PolyNovo’s goal of simplifying delivery, but NovoSorb’s biomaterial scaffold is more advanced for supporting cell survival in non-immune therapies like T1D.

Summary: PolyNovo’s NovoSorb BTM is highly innovative for T1D, offering a biomaterial-based, localized delivery method that outperforms traditional liver transplantation. Gilead and J&J rely on conventional IV infusion, while SQZ, MaxCyte, and BioNTech focus on cell engineering or in vivo reprogramming, none of which match NovoSorb’s unique vascular bed creation for islet cells.
