Osimertinib in Treating Patients with Stage IIIB-IV or Recurrent Non-small Cell Lung Cancer with EGFR Exon 20 Insertion Mutations

Active: Yes
Cancer Type: Lung Cancer NCT ID: NCT03191149
Trial Phases: Phase II Protocol IDs: EA5162 (primary)
Eligibility: 18 Years and older, Male and Female Study Type: Treatment
Study Sponsor: ECOG-ACRIN Cancer Research Group
NCI Full Details:


This phase II trial studies how well osimertinib works in treating patients with non-small cell lung cancer with EGFR exon 20 insertion mutation that is stage IIIB-IV or has come back (recurrent). Osimertinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth.


I. To evaluate the best objective response rate of osimertinib (AZD9291) among patients with EGFR exon 20 insertions.

I. To determine the safety profile of 160 mg once daily (QD) dose of osimertinib (AZD9291) in patients with EGFR Exon 20 insertion mutations.
II. To determine the progression-free survival.
III. To determine the overall survival.

I. To characterize molecular markers of response to treatment in circulating tumor deoxyribonucleic acid (DNA).
II. To evaluate biomarkers of response to treatment through retrospective analyses of pre-treatment tumor tissue.
III. To identify resistance mechanisms to osimertinib (AZD9291) through post-progression tumor biopsies and circulating tumor (ct)DNA.

Patients receive osimertinib orally (PO) once daily (QD) on days 1-21 of each cycle. Cycles repeat every 21 days in the absence of disease progression or unacceptable toxicity. Patients undergo magnetic resonance imaging (MRI) or computed tomography (CT) with contrast and collection of blood samples throughout the trial.

After completion of study treatment, patients are followed up at 30 days and every 3 months for up to 5 years.

**Clinical trials are research studies that involve people. These studies test new ways to prevent, detect, diagnose, or treat diseases. People who take part in cancer clinical trials have an opportunity to contribute to scientists’ knowledge about cancer and to help in the development of improved cancer treatments. They also receive state-of-the-art care from cancer experts... Click here to learn more about clinical trials.
