Our nanoparticle drug-delivery platform reduces local cancer recurrence. By locally and safely delivering chemotherapeutics to residual tumors following a resection surgery, we treat the primary cause of mortality in ovarian, mesothelioma and other peritoneal cancers. This technology accesses a $1B+ (USA) addressable market.
$1B+ (USA) addressable market
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 murine models of peritoneal cancers.

Verticillin A Causes Apoptosis and Reduces Tumor Burden in High-Grade Serous Ovarian Cancer by Inducing DNA Damage (2020)
This paper demonstrates that expansile nanoparticles can effectively deliver new cytotoxic natural products, such as verticillin A, to ovarian cancer cells thereby controlling tumor growth.
Nanoparticle drug-delivery systems for peritoneal cancers: a case study of the design, characterization and development of the expansile nanoparticle (2017)
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.
Highly Specific and sensitive fluorescent nanoprobes for image-guided resection of sub-millimeter peritoneal tumors (2017)
