Stimulate the mind,
Act in the gut.


Viage Therapeutics, a neuroscience company based on a platform of novel neurotherapeutics, was founded in 2018. The company is based on the ground-breaking research of Dr. Kousaku Ohinata from Kyoto University.

DGX-001, Viage’s clinical drug candidate, represents a first-in-class oral drug candidate targeting the gut-brain axis. The proposed mechanism of action of DGX-001 is to modulate the vagus nerve through specific receptor interactions on enteroendocrine cells in the gut, resulting in a regulation of brain cell activity.

DGX-001 is in clinical development and was well-tolerated in a healthy volunteer Phase 1 study, consistent with its positive safety profile in preclinical GLP studies. In the clinical study, DGX-001 increased specific brain activity (EEG measures) and a post hoc analysis indicated improvements in cognition based on Cogstate tests. Furthermore, human PK measurements have so far been undetectable systemically, confirming the preclinical finding the drug candidate is gut-restricted and gut-acting, which may further minimize off-target side effects as majority of PD patients suffer from comorbidities and polypharmacy.

Viage plans to initiate the Phase 2 program of DGX-001, which initially aim to achieve cognitive improvement across different diseases, representing a transdiagnostic study design, which may ultimately enable indications beyond neurology and psychiatry.

Viage’s pipeline is comprised of both novel neuropeptides and 2nd generation DGX-001-derived peptides and small molecules. It includes SAR-optimized drug candidates with potential in cognitive impairment, depression, anxiety, and inflammatory disease. The drug candidates are gut-acting and gut-restricted, which suggests an advantageous safety profile, particularly compared to most approved psychiatric drugs which suffer from numerous side effects.

The Company is headquartered in the San Francisco Bay Area.

Viage Therapeutics announces data from a Phase 1 study with DGX-001, a first-in-class oral neurotherapeutic targeting cognitive impairment in patients with Alzheimer's Disease and Parkinson's Disease

Viage Therapeutics

Viage Therapeutics (Viage), a neuroscience company based on a platform of novel neurotherapeutics, today announced positive findings from its Phase 1 study of DGX-001, a first-in class oral therapeutic targeting the AVPR1A receptor in the gut. DGX-001 demonstrated both a favorable safety profile and proof of concept data relating to its mechanism of action (MoA), which modulates the vagus nerve via specific receptor interactions on enteroendocrine cells in the gut, with no systemic exposure of the drug and no need to penetrate the blood brain barrier.
