C5R facilitates collaboration between Canadian dementia researchers and pharmaceutical industry partners to conduct clinical trials for Alzheimer’s disease, mild cognitive impairment, and other forms of dementia. Member sites across Canada support trials ranging from early-phase to later-stage studies, helping to accelerate therapeutic development and improve patient outcomes.
