## Summary

Received up to $40.7M ARPA-H award (Oct 2025). Polymeric nanoparticle platform to reprogram immune cells in vivo without viral vectors. Non-viral delivery for CAR-T-like therapies.

## Company Overview

ImmunoVec is developing a non-viral polymeric nanoparticle delivery platform for in vivo immune cell engineering — programming a patient's immune cells directly inside their body without the expensive ex vivo manufacturing process that makes CAR-T therapies cost $500,000-$1,000,000 per treatment. The company received a selective ARPA-H (Advanced Research Projects Agency for Health) award of up to $40.7 million in October 2025 for development of its platform.

ARPA-H funding is among the most selective and technically validated health research grants in the US government — the agency specifically funds technologies with potential to radically transform healthcare, not incremental improvements. ARPA-H's selection of ImmunoVec validates the non-viral in vivo CAR-T approach as a genuine national health priority with transformative potential.

The platform's economic implications are significant: current CAR-T therapies require extracting patient T cells, genetically modifying them in specialized GMP facilities, expanding them in culture, and reinfusing them — a 3-4 week process costing $500,000+ per patient. ImmunoVec's in vivo approach could reduce this to an off-the-shelf infusion at 1-5% of current cost, potentially democratizing CAR-T-like immunotherapy for the 90%+ of patients who currently cannot access it.

## Frequently Asked Questions

### What does ImmunoVec do?
Non-viral in vivo immune cell engineering — polymeric nanoparticles reprogram T cells inside the patient's body, eliminating the expensive ex vivo manufacturing that makes CAR-T therapies cost $500K-$1M.

### How much has ImmunoVec received?
Up to $40.7M ARPA-H award in October 2025 — one of the most selective US government health research grants.

### Why does non-viral delivery matter?
Viral vectors (lentivirus, retrovirus) used in current CAR-T therapies are expensive and complex to manufacture. Nanoparticle delivery is cheaper, safer (no viral integration risk), and more scalable.

### What is the cost reduction potential?
Current CAR-T: $500K-$1M per patient (3-4 week ex vivo process). ImmunoVec's in vivo approach could reduce to an off-the-shelf infusion at 1-5% of current cost — democratizing CAR-T for the 90%+ of eligible patients currently priced out.

### What does ImmunoVec's in vivo immune cell engineering platform do?
ImmunoVec delivers gene payloads directly to immune cells (T cells, NK cells) circulating in the bloodstream via engineered viral or non-viral delivery vehicles — eliminating the ex vivo manufacturing step required for current CAR-T and TCR-T cell therapies. The patient receives an IV infusion of the delivery vehicle which selectively targets immune cells in vivo, engineers them genetically, and creates the therapeutic cell population without leaving the body.

### What immune cell types can ImmunoVec target in vivo?
ImmunoVec's platform is designed to selectively target specific immune cell types — T cells (including naive, effector, memory subsets), NK cells, and potentially B cells and regulatory T cells depending on the targeting ligand used. Cell type selectivity is achieved through cell-surface receptor targeting built into the delivery vehicle. This selectivity matters clinically — different CAR or TCR payloads should reach different immune cell populations depending on the disease application.

### How does ImmunoVec's approach address cost barriers in cell therapy?
Current ex vivo CAR-T therapies cost $400,000-500,000 per patient, driven by the individualized manufacturing process. In vivo delivery eliminates: apheresis ($5,000-10,000), central manufacturing (large GMP facility at $100M+ capital cost), lengthy cell culture (3-4 weeks), product quality testing, and cold-chain shipping. If successful, in vivo CAR-T could reduce per-patient manufacturing costs by 80-90%, enabling access for far more patients and potentially expanding to chronic conditions where ex vivo CAR-T economics are currently prohibitive.

### What are the technical risks of ImmunoVec's in vivo approach?
Key technical risks include: achieving sufficient in vivo transduction efficiency (getting enough immune cells edited to provide therapeutic effect), maintaining selectivity for target immune cells without off-target editing, ensuring the delivery vehicles themselves don't trigger immune responses that clear them before sufficient editing occurs, and achieving durable gene expression in long-lived memory T cells rather than short-lived effector cells. Multiple companies are racing to solve these challenges — ImmunoVec's differentiation is its specific delivery vehicle chemistry and cell-targeting ligand design.
