Idylla™ EGFR_IUO/3.20 Mutation Test a Clinical Trial Assay in the AstraZeneca Phase III NeoADAURA Clinical Trial (D516AC00001) Clinical Study Protocol

This is a prospective, interventional diagnostic study using the For Investigational Use Only EGFR_IUO/3.20 for FFPE FNA sections. Screened patients with available FNA specimens, collected per SoC, who are found to have exon 19 deletions or L858R mutations in the EGFR gene based on the results of EGFR_IUO/3.20 and who meet all other study eligibility criteria will be randomized into one of three arms of the NeoADAURA study: neoadjuvant osimertinib as monotherapy or in combination with pemetrexed/platinum chemotherapy, versus pemetrexed/platinum chemotherapy plus placebo.

The use of the investigational IVD does not require invasive sampling that is not part of standard of care (SoC). Investigational testing for patient selection will be performed on FFPE FNA specimens, obtained as SoC for diagnosis and/or pathologic staging prior to definitive surgery. By using available specimens obtained as SoC, there is no risk to patients as a result of invasive sampling for EGFR testing.
