CSTS Health Care

CSTS Health Care is a private Toronto-based precision oncology biotechnology company developing cancer therapies intended to improve efficacy while reducing systemic toxicity. The company’s core technology is Cytesia, a platelet-facilitated drug platform used to create Platelet Facilitated Drugs (PFDs) that deliver precision drug combinations to disease-relevant sites. CSTS positions its approach as a way to enable more personalized oncology treatment and better tolerability versus conventional anticancer therapy. Publicly available information indicates the company remains at the pre-clinical stage, with its work centered on platform and patent development rather than disclosed late-stage clinical assets.
