PAX Therapeutics, having completed IND-enabling studies, is on the cusp of clinical trials to demonstrate optimized tendon healing by the delivery of our growth factor vector which in preclinical studies resulted in faster stronger healing with fewer adhesions. Seventeen (17) million tendon and ligament injuries occur per year in the US with a $40 Billion economic impact. Surgical repair of ruptures requires a long time to heal (note the NBA players who miss an entire season), and often results in re-ruptures, limited range-of-motion, adhesions, and pain. PAX-001 in the best animal model of tendon rupture resulted in nearly 4X stronger healing by 4 weeks and no adhesions because unlike surgery alone, the desired Type 1 collagen is laid down immediately rather than Type 3 (scar) collagen. Our initial clinical target is flexor hand tendon repairs (example: “Guacamole hand”) then will extend to other tendon and ligament rupture repairs.
