Once subjects on the platinum-based doublet chemotherapy arm are determined to have objective radiological progression according to RECIST 1.1 by the investigator and confirmed by independent central imaging review, they will be given the opportunity to begin treatment with Osimertinib 80mg, once daily. These subjects may continue treatment with Osimertinib even after disease progression, as long as they are continuing to show clinical benefit, as judged by the investigator. Subjects who stop platinum-based doublet chemotherapy for reasons other than objective disease progression according to RECIST 1.1 will not be eligible to cross-over to Osimertinib.

primary Outcomes

description
Per Response Evaluation Criteria in Solid Tumours (RECIST v1.1) assessed by MRI or CT: Progressive Disease (PD): \>= 20% increase in the sum of diameters of TLs and an absolute increase in sum of diameters of \>=5mm (compared to the previous minimum sum) or progression of NTLs or a new lesion. PFS is the time from date of randomisation until the date of PD (by investigator assessment) or death (by any cause in the absence of progression) regardless of whether the patient withdrew from randomised therapy or received another anti-cancer therapy prior to progression.

Full study description

brief Summary: A Phase III, Open Label, Randomized Study of Osimertinib versus Platinum-Based Doublet Chemotherapy for Patients with Locally Advanced or Metastatic Non-Small Cell Lung Cancer whose Disease has Progressed with Previous Epidermal Growth Factor Receptor Tyrosine Kinase Inhibitor Therapy and whose Tumours harbour a T790M mutation within the Epidermal Growth Factor Receptor Gene
detailed Description: This is a phase III, open label, randomized study assessing Osimertinib (80 mg, orally, once daily) versus platinum-based doublet chemotherapy (standard of care) in subjects with confirmed diagnosis of Epidermal Growth Factor Receptor (EGFR) mutation positive NSCLC, who have progressed following prior therapy with an approved Epidermal Growth Factor Receptor Tyrosine Kinase Inhibitor (EGFR-TKI) agent and whose tumours harbour a T790M mutation within the EGFR Gene. Subjects must be chemotherapy naive and must agree to provide a biopsy for central confirmation of T790 mutation status following confirmed disease progression on their first line EGFR-TKI treatment (e.g. erlotinib, gefitinib or afatinib). Suitable subjects will then be randomized to receive either Osimertinib (80mg orally, once daily) or platinum-based doublet chemotherapy (pemetrexed 500 mg/m2 + carboplatin area under the plasma concentration-time curve AUC 5 or pemetrexed 500 mg/m2 + cisplatin 75 mg/m2) on Day 1 of every 21-day cycle in a 2:1 (Osimertinib: platinum-based doublet chemotherapy) ratio. Once subjects on the platinum-based doublet chemotherapy arm are determined to have objective radiological progression according to RECIST 1.1 by the investigator and confirmed by independent central imaging review, they will be given the opportunity to begin treatment with Osimertinib 80mg, once daily. These subjects may continue treatment with Osimertinib even after disease progression, as long as they are continuing to show clinical benefit, as judged by the investigator. The primary objective of the study is to assess the efficacy of Osimertinib compared with platinum-based doublet chemotherapy by assessment of Progression Free Survival (PFS), using investigator assessments according to Response Evaluation Criteria in Solid Tumours (RECIST 1.1), as well as asensitivity analysis of Progression Free Survival using Blinded Independent Central Review (BICR).
