About CLN-081

CLN-081 is an orally available, irreversible EGFR inhibitor that was designed to selectively target cells expressing mutant EGFR variants, including Ins20, while sparing cells expressing wild type EGFR. In preclinical studies, CLN-081 demonstrated inhibition against traditional sensitizing mutations (exon 19 deletions and L858R), Ins20 (the third most common EGFR mutation), and other less common mutations (G719X, L861Q, and S768I).

Cullinan is evaluating various doses of CLN-081 in a Phase 1/2a trial in patients with NSCLC harboring Ins20 mutations that have progressed post chemotherapy. Based on pre-specified efficacy and safety criteria, Cullinan recently initiated Phase 2a dose expansion in the 100 mg BID dosing cohort, which will enable enrollment of up to 36 patients at this dose level, inclusive of 13 previously enrolled patients.
