EvoRx Technologies | About
EvoRx strives to discover and develop innovative peptide therapeutic and targeted radiopharmaceuticals for treatment and diagnosis of disease with high unmet medical need. It’s proprietary Evo-Link™ technology rapidly generates exceedingly high diversity cyclic peptide libraries. The libraries are screened for drug-like activity in environments that mimic the physiological environment of the body. This results in EvoTides™, uniquely structured peptides that are highly stable in human serum, have antibody-like specificity and affinity, and can be designed to be membrane permeable. These features allow us to target protein interactions previously thought of as “undruggable.”

Targeting Intracellular Protein-Protein Interactions

The role of many intracellular Protein-Protein Interactions (PPIs) in disease has been well studied. However, translating this knowledge to novel therapeutics has been difficult due to challenges in targeting intracellular PPIs with small molecules and their inaccessibility to antibodies. By some estimates, ~70% of proteins implicated in disease formation are considered “undruggable” by traditional approaches. We at EvoRx Technologies believe that unlocking these targets will be key in developing treatments for life threatening diseases, such as cancer, that represent a high unmet clinical need.

EvoRx discovers and develops novel macrocyclic peptides for modulating intracellular PPIs. We design, generate and screen 500 billion member peptide libraries for drug-like properties including cell permeability, stability in complex media such as human serum, and high target specificity. This results in membrane permeable hits able to be easily optimized by standard medicinal chemistry techniques and able to target intracellular PPIs. We have successfully deployed this technology in collaboration with major pharmaceutical companies, such as AstraZeneca, to aid in their discovery efforts.

Targeting Cell-Surface Receptors for the Diagnosis and Treatment of Disease

Inflammatory Breast Cancer

Inflammatory breast cancer (IBC) is a highly aggressive disease with a five-year survival rate below 30%. IBC is difficult to detect on mammograms and challenging to biopsy since it does not form a discrete lump. This often leads to an imprecise diagnosis and staging. Many patients with IBC are Her2-positive and data suggests that patients could benefit from anti-Her2 therapies. However, mis-staging or lack of assessment for Her2 status may prevent or delays access to Her2 therapies.

Using our proprietary technology platform, EvoRx Technologies is developing a Positron Emission Tomography (PET) imaging agent to help accurately assess Her2 status for primary and secondary tumors and to help monitor the course of Her2 treatment in IBC. In parallel, we are developing a targeted radiotherapy for Her2 that can deliver radiation more specifically and effectively to the tumor than traditional radiation treatments.
