Company Overview

COMPANY OVERVIEW

PAX Therapeutics is a US-based company dedicated to optimize healing of tendon and ligament injuries to restore full mobility and improved function faster than current approaches.

Spun out of the labs at Rhode Island Hospital (a major teaching affiliate of The Warren Alpert Medical School of Brown University) of Dr. Paul Liu, a Harvard Medical School-trained surgeon-scientist, PAX Therapeutics provides a unique approach that capitalizes on the advances in gene delivery that have made vectors a safe technology for regenerative medicine, vaccines, and use in infants/children. PAX-001 provides a biological mechanism to optimize healing besides the surgical intervention, because it results in the desired Type 1 collagen to be produced from the start, rather than scar (Type 3) collagen). 

 

Research over 15 years performed in the founder’s academic lab led to the specific combination of vector and growth factor gene and mechanism of healing for use for both tendons and ligaments and for human (and eventually veterinary) applications.
