A Study of VRN110755 in Patients With EGFR-Mutant Non-Small Cell Lung Cancer
brief summary
This first-in-human, Phase 1/2, multicenter, open-label, non-randomized study evaluates the safety, tolerability, pharmacokinetics, pharmacodynamics, and antitumor activity of VRN110755, a highly selective oral epidermal growth factor receptor (EGFR) inhibitor, in patients with EGFR-mutant non-small cell lung cancer (NSCLC). The study includes a Phase 1a dose-escalation portion, a Phase 1b dose-expansion portion, and a Phase 2 evaluation. The study is designed to determine the maximum tolerated dose and recommended Phase 2 dose of VRN110755 and to evaluate preliminary and confirmatory antitumor activity in patients with EGFR-mutant NSCLC, including patients with acquired resistance following EGFR tyrosine kinase inhibitor therapy.
detailed description
This is a Phase 1/2, multicenter, open-label, non-randomized, dose-escalation and dose-expansion clinical trial evaluating VRN110755 administered as oral monotherapy once daily in 28-day treatment cycles.
Phase 1a uses a standard 3+3 dose-escalation design to evaluate safety, tolerability, dose-limiting toxicities, pharmacokinetics, pharmacodynamics, and preliminary antitumor activity and to determine the maximum tolerated dose (MTD).
Phase 1b evaluates safety, tolerability, pharmacokinetics, pharmacodynamics, and preliminary antitumor activity across molecularly defined EGFR-mutant NSCLC cohorts and determines the recommended Phase 2 dose (RP2D).
Following determination of the RP2D, selected expansion cohorts will continue into the Phase 2 portion to further evaluate the efficacy, safety, tolerability, and pharmacokinetics of VRN110755. The specific Phase 2 cohorts will be selected based on the safety and efficacy data generated during Phase 1b.
Participants remain on treatment until disease progression, unacceptable toxicity, withdrawal of consent, initiation of another anticancer therapy, death, or study completion.
