Our lead drug candidate, AV-101, is an orally-available, non-sedating prodrug that is rapidly converted in vivo
to its active metabolite, 7-chlorokynurenic acid (7-Cl-KYNA), one of the most well-characterized, potent and selective synthetic blockers of N-methyl-D-aspartate (NMDA) receptors at the glycine-coagonist (GlyB) site. However, 7-Cl-KYNA does not cross the blood-brain barrier, making it a poor drug candidate. AV-101, the prodrug of 7-C1-KYNA, readily gains access to the CNS after systemic administration and is converted to 7-Cl-KYNA by astrocytes that are activated at sites of neuronal injury or excitotoxic insult, making it a potential treatment for multiple diseases and disorders involving the central nervous system (CNS), including Major Depressive Disorder (refractory depression), refractory epilepsy, neuropathic pain and neurodegenerative diseases such as Parkinson’s disease and Huntington’s disease. We have successfully completed Phase 1 development of AV-101, demonstrating that AV-101 is well tolerated, without any significant safety issues. AV-101 is a now potential Phase 2 development candidate for the treatment of multiple diseases and disorders involving the central nervous system (CNS), including, Major Depressive Disorder (refractory depression), refractory epilepsy, neuropathic pain, and neurodegenerative diseases such as Parkinson’s disease and Huntington’s disease.
™, our mature human cardiomyocytes (human heart cells) differentiated from pluripotent stem cells, we have developed CardioSafe
3D™, a novel, customized in vitro
bioassay system for assessing new small molecule drug candidates, including drug rescue candidates and drug rescue variants, for potential cardiac toxicity, long before they are tested in animals or humans. We believe CardioSafe
3D is capable of predicting the in vivo
cardiac effects, both toxic and non-toxic, of small molecule drug candidates more comprehensively and efficiently than conventional surrogate safety models often used in drug development, including the hERG assay and models using live animals or animal, transformed or immortalized cells.
™, our mature, human hepatocytes (human liver cells) derived from pluripotent stem cells, we are developing LiverSafe
3D, our second novel customized bioassay system for drug discovery, rescue and development. We believe LiverSafe
3D will enable us to assess new drug candidates, including drug rescue candidates and drug rescue variants, for potential liver toxicity and metabolism-based safety issues resulting in adverse drug-drug interactions, early in development, long before animal and human testing. Drug-related liver toxicity and adverse drug metabolism, as a group, represent one of the top-two reasons for safety-related drug failure during clinical development.
