1 A Randomised Phase II Trial of Osimertinib With or Without Stereotactic Radiosurgery for EGFR Mutated Non-Small Cell Lung Cancer (NSCLC) With Brain Metastases

20-40% of patients with NSCLC will develop brain metastases at some point during their course of disease. Osimertinib has demonstrated intracranial activity in EFGR mutated NSCLC with leptomeningeal disease in the phase 1 BLOOM study. Stereotactic radiosurgery (SRS) is one of the standard local treatment for patients with limited number of brain metastases. Currently, it is unclear whether adding SRS to Osimertinib will result in superior intracranial disease control in patients with EGFR mutated NSCLC with brain metastases diagnosed de novo or developed while on first line EGFR tyrosine kinase inhibitors (TKIs) such as Erlotinib and Gefinitib. The aim of this study is to compare the effects of Osimertinib alone versus SRS plus Osimertinib on intra-cranial disease control in EGFR mutated NSCLC with brain metastases diagnosed or developed while on first line EGFR tyrosine kinase inhibitors.

NCT03497767 Metastatic Non Small Cell Lung Cancer Drug: Osimertinib Radiation: Stereotactic Radiosurgery (SRS)
MeSH:Lung Neoplasms Carcinoma, Non-Small-Cell Lung
HPO:Neoplasm of the lung Non-small cell lung carcinoma

2. Documented EGFR mutation (at any time since the initial diagnosis of NSCLC) known to be sensitive to Osimertinib - These include exon 19 del; L858R (exon 21); G719X (exon 18); L861G (exon 21); S768I (exon 20) and T790M (exon 20) NOTE: Mutation analysis is to be done as per local practice. --- L858R --- --- L861G ---

Primary Outcomes

Description: To assess the efficacy of Osimertinib with deferred local brain metastases directed therapies compared with upfront SRS followed by Osimertinib by assessment of intracranial progression free survival at 12 months.

Measure: Intracranial progression free survival at 12 months

Time: 12 months post randomisation

Secondary Outcomes

Description: To assess the effect of Osimertinib with deferred local brain metastases directed therapies compared with upfront SRS followed by Osimertinib on use of salvage whole-brain radiotherapy (WBRT) +/- neurosurgery.

Measure: Use of salvage whole-brain radiotherapy (WBRT)

Time: 18 months post randomisation

Description: To assess the effect of Osimertinib with deferred local brain metastases directed therapies compared with upfront SRS followed by Osimertinib on local brain failure.

Measure: Local brain failure

Time: 18 months post randomisation

Description: To assess the effect of Osimertinib with deferred local brain metastases directed therapies compared with upfront SRS followed by Osimertinib on distant brain failure.

Measure: Distant brain failure

Time: 18 months post randomisation

Description: To assess the effect of Osimertinib with deferred local brain metastases directed therapies compared with upfront SRS followed by Osimertinib on extra-cranial progression.

Measure: Extra-cranial progression

Time: 18 months post randomisation

Description: To further assess the efficacy of Osimertinib with deferred local brain metastases directed therapies compared with upfront SRS followed by Osimertinib in terms of overall survival.

Measure: Overall Survival

Time: 18 months post randomisation
