NCT06067776 | NOT YET RECRUITING | Metastatic Lung Non-Small Cell Carcinoma

Osimertinib, Cetuximab, and Tucatinib for the Treatment of EGFR-Mutant Stage IV or Recurrent Non-small Lung Cell Cancer

Brief 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.

Detailed 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 EGFR-TKI (osimertinib). III. To obtain preliminary assessment of anti-tumor activity of osimertinib, cetuximab, and tucatinib in the dose expansion cohort of participants with EGFR-mutant NSCLC who progressed on first-line osimertinib and do not have non-ERBB bypass tract mechanisms of resistance, including a subset of participants positive for HER2 aberrant signaling as determined by immunohistochemistry (IHC), fluorescence in situ hybridization (FISH) and/or next generation sequencing (NGS). OUTLINE: This is a dose-escalation study of tucatinib and cetuximab. Patients receive tucatinib 200mg orally BID, osimertinib 80mg orally daily, and cetuximab 250mg/m\^2 IV every 2 weeks of a 28-day cycle. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity. After completion of study treatment, patients are followed up at 30 days and every 12 weeks for up to 2 years.

Criteria
Inclusion Criteria
  • * Participants with Stage IV or recurrent/metastatic histologically confirmed non-small cell lung cancer (NSCLC).
  • * NSCLC must harbor at least one of the following EGFR activating mutations: Exon 21 L858R, Exon 19 deletion, Exon 18 G719X, Exon 21 L861Q, Exon 20 S768I.
  • * For patients in the dose escalation cohort, patients must have progressed on any prior EGFR-Tyrosine Kinase Inhibitor (TKI) and if T790M positive must have also progressed on osimertinib. Participants in the dose expansion cohort must have had progressive disease as assessed by Response Evaluation Criteria In Solid Tumors (RECIST) version (v)1.1 criteria on osimertinib as first-line therapy.
  • * 4. Participants in the dose expansion cohort must be negative for clinically significant non-ERBB bypass tract resistance such as MET amplification, BRAF mutation, RAS-RAF-MAPK alteration, ALK fusion, RET fusion by a Clinical Laboratory Improvement Amendments (CLIA) (performed after progression on prior EGFR-TKI; if any questions please consult with the Principal Investigator). A defined subset of patients in the expansion cohort will have human epidermal growth factor receptor (HER2) aberrant signaling as putative resistance to osimertinib with overexpression/amplification (or more rarely HER2 Exon 20 insertion mutation) as determined by IHC (3+ IHC) or FISH (HER2/CEP17 \> 2.2 or HER2 copy number \> 6) or NGS for HER2 mutation.
  • * Adequate archival tissue from a biopsy performed after progression of disease on previous osimertinib (or last EGFR-TKI for dose escalation cohort) or willingness to consent for a fresh tumor biopsy.
  • * Participants must have measurable disease by RECIST 1.1, by positron emission tomography/computed tomography (PET/CT) or CT imaging within 28 days prior to registration. The CT from a combined PET/CT may be used only if it is of diagnostic quality.
