Ther4

  • Ther4 is an ApoA-I fusion protein providing the main protein associated with HDL​
  • ApoA-I typically has short half-life in the lipid-free state, whereas Ther4 has a longer half-life​
  • One indication is to improve reverse cholesterol transport with potential to stabilize and/or reduce coronary plaques​
  • ApoA-I can also neutralize LPS which is the endotoxin that drives gram-negative sepsis
  • A second indication is to reduce the endotoxemia burden of sepsis which can reduce sepsis-associated kidney failure and other complications leading to decreased ICU stay, morbidity and mortality
  • ApoA-I is a powerful anti-inflammatory molecule typically associated with its actions with or without HDL.
  • A third indication is utility in autoimmune disease to improve and resolve inflammation in diseases like inflammatory bowel disease, rheumatoid arthritis and others.

TR-43​

  • PON1 Fc molecule providing the antioxidant enzyme paraoxonase 1​
  • This is a first-in-class molecule providing a long half-life to this important enzyme​
  • The enzyme is deficient in many diseases including fibrosis and inflammation
  • There is also potential of this enzyme to provide protection from harmful chemicals such as pesticides and chemical nerve agents
  • Recent literature suggests a potential use as a tumor “metabolic” checkpoint inhibitor that can reduce tumor burden in hepatocellular carcinoma either alone or synergistically with immune checkpoint inhibitors
  • There are promising data regarding prevention of diabetes in a rodent model of type 1 diabetes and treatment of insulin resistance in a different rodent model using recombinant PON 1​

Paraoxonase Fusion Protein Platform

  • Bispecific molecules combined with the antioxidant enzyme paraoxonase 1​
  • This is a first-in-class platform providing combination therapies for a multitude of diseases including heart disease and inflammatory conditions
  • US patent issued 12/31/24 covering Theripion bifunctional PON1 molecules
