About this study

This phase II single-armed study will examine the clinical utility of retreating patients with osimertinib, in the third-line, following first-line treatment with osimertinib and second-line treatment with platinum and pemetrexed chemotherapy. The current standard of care for first-line Epidermal Growth Factor Receptor (EGFR) mutated Advanced Non-Small Cell Lung Cancer (aNSCLC) is osimertinib, followed by cytotoxic chemotherapy. The repeat of osimertinib following previous treatment failure is investigational, although supported by scientific rationale. The dosing and scheduling of osimertinib follows its use in approved settings. The investigators examine its tolerability and efficacy in this setting to ensure osimertinib is a safe third-line option for patients with Epidermal Growth Factor Receptor mutated (EGFR+) Advanced Non-Small Cell Lung Cancer(aNSCLC).
