Job Details

Theseus Pharmaceuticals is passionately committed to improving the lives of cancer patients by working to outsmart cancer resistance. Led by a team of targeted oncology pioneers with a proven track record developing and commercializing cancer therapeutics, we are developing the next generation of tyrosine kinase inhibitors (TKIs): “pan-variant” targeted therapies that address all known drug-resistant mutations. We believe a pan-variant approach is the only way to address cancer resistance. Our lead program, THE-630, is a pan-variant KIT inhibitor for patients with advanced gastrointestinal stromal tumors (GIST), whose cancer has developed resistance to earlier lines of kinase inhibitor therapy. We are also developing a fourth-generation, selective epidermal growth factor receptor (EGFR) inhibitor to address C797S-mediated resistance to first- or later-line osimertinib treatment in patients with non-small cell lung cancer (NSCLC).
