Vertero is innovating beyond the brain to develop differentiated therapies to turn the tide of challenging neurodegenerative diseases and preserve patients’ quality of life for longer.
While many standard-of-care therapies address the symptoms, our discoveries target causative mechanisms that lie outside the brain, in the peripheral nervous system.
Our multidisciplinary team of specialists in microbiology, pharmacology, chemistry, neurology, and clinical development have allowed us to create a novel and groundbreaking approach to the treatment of neurodegenerative diseases.
Our team is powered by strong technical acumen combined with a culture of transparency, collaboration, curiosity, and persistence to deliver on real unmet needs.
