Most cancer therapies are limited by toxicity and only work for specific cancer subtypes. At HemePro our therapies broadly and effectively target many types of cancer — with demonstrated efficacy in hard-to-treat lung and breast cancers — and have a remarkable safety profile. Our patented biologics (called HeSPs) effectively ‘starve' cancer cells by sequestering extracellular heme, a vital nutrient for tumor energy production. Healthy cells are unaffected as they do not need this heme.
