Born out of the Therapeutic Development Group at the Campbell Family Institute for Cancer Research in Toronto, TIO Discovery provides R&D and management services to TIO Bioventures portfolio companies.
TIO Discovery, in collaboration with the laboratories of renowned innovators including Drs. Tak Mak, Fred Alt, and Mark Davis, has validated multiple novel targets, developed next-generation biologic platforms and differentiated cell therapy technologies, and has advanced three first-in-class/best-in-class small molecule therapeutic candidates into clinical development. These innovations form the foundations of three of the first five of TIO Bioventures’ portfolio companies, including Treadwell Therapeutics, a clinical-stage biotechnology company focusing on first-in-class small molecules addressing unmet needs in Cancer.
Not only serving as TIO Bioventures’ research and development arm, TIO Discovery also provides flexible management talent and advisory to the firm’s portfolio companies, further leveraging our global network of experts to rapidly and efficiently advance breakthrough therapeutics.
