Nanoparticle Solutions to Cancer

Our Value Proposition

Nanoparticle-based drug delivery systems suffer from poor accumulation in tumors with traditional "active" or "passive" targeting strategies netting a median delivery efficiency of just 0.7% of the injected dose reaching the tumor.

Our solution to this problem is a novel, patented, expansile nanoparticle that employs a unique Materials-Based Targeting strategy to achieve a 50X improvement in delivery efficiency compared to traditional systems. With this improvement, we demonstrate an increase in survival of over 200% compared to clinical standard of care in ovarian cancer and intraperitoneal mesothelioma.

Treatments for ovarian cancer and intraperitoneal mesothelioma represent a market of ~$250M with additional potential markets in pancreatic, colorectal and other gastric cancers of over $750M.

How it Works

Paclitaxel-loaded expansile nanoparticles, or "PTX-eNPs" for short, localize to intraperitoneal tumors with over 95% accuracy. Once inside a tumor, eNPs swell causing the particle to become stuck whereupon the payload (a drug called paclitaxel) is released, killing the cancer cell.

Nanoparticle drug-delivery systems for peritoneal cancers: a case study of the design, characterization and development of the expansile nanoparticle

This paper summarizes the pre-clinical development of the expansile nanoparticle technology from its inception through mid-late preclinical efficacy and pharmacokinetics studies. In addition to its use as a drug delivery system, several additional applications are described including use as a fluorescent-guide for cytoreductive surgery and as tool for two-step delivery.
