To date ACT’s Run for Nana team has raised over $100,000 towards microbiota transplant therapy research and patient treatments. Achieving Cures Together partners with the University of Minnesota and other world-leading academic researchers to manufacture safe and effective microbiota therapies for C. difficile patients and clinical trials targeting multiple health conditions including Ulcerative Colitis, Crohn’s Disease, Autism, Cancer Recovery, Advanced Liver Disease and more.
