Drug Information available for: Osimertinib

Arm Intervention/treatment
Active Comparator: SRS + Osimertinib
Stereotactic radiotherapy will be delivered in 1-5 fractions to each brain metastases according to the volume and location of the metastases and clinician discretion. Osimertinib will start 1-7 days post radiotherapy.
Drug: Osimertinib
Daily oral osimertinib

Radiation: Stereotactic radiotherapy
1-5 fractions of stereotactic radiotherapy

Experimental: Osimertinib alone
Osimertinib 80mg PO daily
Drug: Osimertinib
Daily oral osimertinib

Primary Outcome Measures :
  1. Intracranial progression free survival [ Time Frame: 1 year ]
    Absence of progressive brain metastases according to the Response Assessment in Neuro-Oncology Brain Metastasis (RANO-BM criteria)

Secondary Outcome Measures :
  1. Intracranial overall response rate [ Time Frame: 2 years ]
    partial or complete response to therapy based on RANO-BM criteria

  2. Time to whole brain radiotherapy (WBRT) [ Time Frame: 2 years ]
    time from randomization to WBRT

  3. Time to stereotactic radiosurgery (SRS) [ Time Frame: 2 years ]
    time from randomization to SRS (not including initial SRS in the SRS + osimertinib treatment arm)

  4. 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

  5. Overall survival [ Time Frame: 2 years ]
    defined as time from randomization to death by any cause

  6. 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

  7. 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)

  8. Neurocognitive function [ Time Frame: 2 years ]
    Assessed by Montreal Cognitive Assessment. Total score:30. 1=poor function; 30=good function

  9. Exposure to osimertinib [ Time Frame: 2 years ]
    Osimertinib dose (40mg or 80mg) for x number of days (max=730 days)
