A Phase I Study of Osimertinib, Cetuximab, and Tucatinib in Advanced EGFR-Mutant NSCLC With Acquired Resistance to Osimertinib
Jonathan Riess
Summary
This phase I trial tests the safety, side effects, and best dose of osimertinib, cetuximab, and tucatinib in treating patients with EFGR-mutant non-small cell lung cancer that is stage IV or has come back (recurrent). Osimertinib and tucatinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Cetuximab is a chimeric human/mouse IgG1 monoclonal antibody that targets epidermal growth factor receptor (EGFR), a receptor overexpressed in many types of cancer, and may interfere with the ability of tumor cells to grow and spread. Giving osimertinib, cetuximab, and tucatinib may work better in treating patients with non-small cell lung cancer.
Description
PRIMARY OBJECTIVE : I. To estimate the maximum tolerated dose (MTD) of osimertinib, cetuximab, and tucatinib in participants with EGFR-mutant non-small cell lung cancer (NSCLC) who have acquired resistance to EGFR-tyrosine kinase inhibitor (TKI). SECONDARY OBJECTIVES: I. To evaluate the toxicities of osimertinib, cetuximab, and tucatinib in participants with EGFR-mutant NSCLC who have acquired resistance to EGFR-TKI. II. To obtain preliminary assessment of anti-tumor activity of osimertinib, cetuximab, and tucatinib in participants with EGFR-mutant NSCLC who have acquired resistance to EGF…
