Clinical trials

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.

This Clinical trial is being done to understand how food and a common stomach-acid reducing medicine (called a proton pump inhibitor-PPI) affect how the body absorbs a new drug, VRN101099, in healthy adults. Researchers will measure how much of the drug gets into the bloodstream and how fast it gets there in each situation. This will help identify the most effective way for future patients to use VRN101099 in the treatment of solid tumors and cancers. The main questions it aims to answer is: 1. Does food or a PPI change how the body absorbs a single dose of VRN101099? 2. Is a single dose of VRN101099 safe and well tolerated when taken with or without food or a PPI? 3. How is VRN101099 removed through urine when taken with or without food or a PPI?

This FIH open-label study aims to investigate the safety, tolerability, pharmacokinetics (PK), pharmacodynamics, and antitumor effect of VRN101099 in patients with HER2-positive solid tumors for whom no standard therapies are available.
