The abstract selected for online publication was submitted on
THE-630 is a pan-variant tyrosine kinase inhibitor (TKI) of the receptor tyrosine kinase KIT, designed for patients with GIST that have developed resistance to earlier lines of therapy. The primary objectives of the phase 1 dose escalation portion of the study are to evaluate the safety profile of THE-630, including the determination of a recommended phase 2 dose (RP2D) in GIST patients who have received imatinib and at least one other TKI. Secondary objectives include determining the PK profile of THE-630, and to characterize preliminary evidence of antitumor activity.

About
Theseus is a clinical-stage biopharmaceutical company focused on improving the lives of cancer patients through the discovery, development, and commercialization of transformative targeted therapies. Theseus is working to outsmart cancer resistance by developing pan-variant tyrosine kinase inhibitors (TKIs) to target all classes of cancer-causing and resistance mutations that lead to clinically relevant variants in a particular protein in a given type of cancer. Theseus' lead product candidate, THE-630, is a pan-variant KIT inhibitor for the treatment of patients with advanced gastrointestinal stromal tumors (GIST), whose cancer has developed resistance to earlier lines of kinase inhibitor therapy. Theseus is also developing THE-349, a fourth-generation, selective epidermal growth factor receptor (EGFR) inhibitor for C797X-mediated resistance to first- or later-line osimertinib treatment in patients with non-small cell lung cancer (NSCLC), and a pan-variant BCR-ABL inhibitor for the treatment of relapsed/refractory chronic myeloid leukemia (CML) and newly diagnosed
