Change History
Current Secondary Outcome Measures  ICMJE
 (submitted: December 6, 2018)
  • Intracranial overall response rate [ Time Frame: 2 years ]
    partial or complete response to therapy based on RANO-BM criteria
  • Time to whole brain radiotherapy (WBRT) [ Time Frame: 2 years ]
    time from randomization to WBRT
  • Time to stereotactic radiosurgery (SRS) [ Time Frame: 2 years ]
    time from randomization to SRS (not including initial SRS in the SRS + osimertinib treatment arm)
  • Rate of radionecrosis [ Time Frame: 2 years ]
    according to institutional standards based on radiologic findings with or without pathologic confirmation and multidisciplinary review when required
  • Overall survival [ Time Frame: 2 years ]
    defined as time from randomization to death by any cause
  • Time to distant progression [ Time Frame: 2 years ]
    time from randomization to progression of extracranial metastases or development of new sites of disease per RECIST 1.1
  • Quality of life [ Time Frame: 2 years ]
    Assessed by European Organisation for Research and Treatment of Cancer (EORTC) Quality of Life Questionnaire (QLQ) C30. Subscales for: general presence of symptoms in patients with cancer question 1-28 (1=Not at all; 4=very much); overall health/quality of life question 29-30 (1=very poor; 7=excellent) & EORTC-QLQ Brain Neoplasm (BN)20: Subscales for presence of symptoms in patients with brain tumours question 31-50 (1=Not at all; 4=very much)
  • Neurocognitive function [ Time Frame: 2 years ]
    Assessed by Montreal Cognitive Assessment. Total score:30. 1=poor function; 30=good function
  • Exposure to osimertinib [ Time Frame: 2 years ]
    Osimertinib dose (40mg or 80mg) for x number of days (max=730 days)

Descriptive Information
Brief Title  ICMJE Study of Osimertinib + SRS vs Osimertinib Alone for Brain Metastases in EGFR Positive Patients With NSCLC
Official Title  ICMJE Open Label, Multicenter, Phase II Study of Patients With Treatment Naïve Metastatic Epidermal Growth Factor Receptor (EGFR) Mutation-Positive Non-Small Cell Lung Cancer (NSCLC) With Brain Metastases Randomized to Stereotactic Radiosurgery (SRS) and Osimertinib or Osimertinib Alone
Brief Summary This open-label, multicenter, randomized phase II study will evaluate the usage of osimertinib alone for brain metastases compared to SRS and osimertinib in patients with newly diagnosed, treatment naiive EGFR positive lung cancer.
Detailed Description Not Provided
Study Type  ICMJE Interventional
Study Phase  ICMJE Phase 2
Study Design  ICMJE Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Condition  ICMJE
  • Lung Cancer Non-small Cell Stage IV
  • Brain Metastases
Intervention  ICMJE
  • Drug: Osimertinib
    Daily oral osimertinib

Eligibility Criteria  ICMJE

Inclusion Criteria:

  • Able to provide written informed consent by patient or legally acceptable representative
  • Meets the criteria in the approved regulatory indication for first line treatment with osimertinib and agree to the restrictions, monitoring, and dose-adjustment criteria stipulated in the associated product label
  • Epidermal growth factor receptor (EGFR) exon 19 deletions or exon 21 (L858R) substitution mutations (either alone or in combination with other EGFR mutations)
  • No prior systemic therapy except neoadjuvant, adjuvant or concurrent chemotherapy given greater than 3 months prior to enrollment on study
  • Asymptomatic or minimally symptomatic brain metastases (ie. Headache, nausea, or seizure responsive to dexamethasone/analgesic/antiepileptic on stable doses of medications for a minimum of 3 days)
  • Brain metastases must meet the following criteria on a diagnostic MRI: at least one lesion can be classified as measurable disease per RANO-BM, ≤ 10 brain or brainstem metastases, ≤ 30 mm and brainstem metastases must be ≤ 5 mm, metastases > 5 mm from the optic nerve or chiasm
  • ECOG performance status 0-2

Exclusion Criteria:
