Roche initiates Phase 1 clinical trial of investigational drug for Down syndrome

Sep 12 2011

Roche (SIX: RO, ROG; OTCQX: RHHBY) today announced the initiation of its first Phase 1 clinical trial to investigate the safety and tolerability of a molecule designed to address the cognitive and behavioral deficits associated with Down syndrome.

"There is currently a large unmet medical need for the treatment of cognitive impairments in individuals suffering from Down syndrome," comments Luca Santarelli, Global Head of Roche Neurosciences Disease Translational Area. "Our strategy at Roche neurosciences is to specifically address these serious conditions that have no approved, effective or safe treatment. This is why we have a strong commitment to neurodevelopmental disorders, including genetic disorders like Down syndrome or Fragile X, as well as autism spectrum disorders."  

Enhancing brain functions such as cognition and language in individuals with Down syndrome holds the promise to help these individuals conduct a more independent life. This may result from the improved ability to carry out every day's practical tasks such as finding an apartment, maintaining a job, or having a more fulfilling social life. These improvements can have a significant impact on functioning and quality of life of Down syndrome individuals as well as help reduce the burden for families, caregivers and the society.

"This study will target only adults between 18 and 30 years old, but we believe that an earlier intervention in Down syndrome has the potential for a greater medical impact," says Paulo Fontoura, Head of Translational Medicine in the Roche Neurosciences Disease Translational Area. "While we are still at the early stage, we are confident that our drug's mechanism of action can potentially open the door to further promising investigations in upcoming years."

Based on animal models, an imbalance between excitatory and inhibitory neurotransmission has been proposed among the underlying causes of altered brain function in individuals with Down syndrome. Roche's investigational drug is being assessed for its ability to address this imbalance by targeting the GABAergic system.
