Brief Summary:
Brain metastases occurs in up to 50% of patients with EGFR mutant NSCLC. Leptomeningeal disease is a subset of patients with brain metastases for which there remains an unmet need. This trial aims to evaluate the role of two dosing schedules of afatinib in management of leptomeningeal disease in EGFR mutant NSCLC, specifically to determine Central Nervous System (CNS) penetration of afatinib, as well as clinical activity. Patients will start on daily dosing initially followed by pulsed intermittent dosing should we observe no clinical activity. A secondary objective is to identify the resistance spectrum in leptomeningeal disease. It is anticipated that optimal dosing schedule of afatinib e.g. pulsed dosing may improve CNS disease control.

Arm Intervention/treatment
Experimental: Part A
Standard dose oral afatinib. If patients in Part A do not benefit from the regimen, they can be enrolled into Part B
Drug: Afatinib
40mg daily
Other Name: Gilotrif

Experimental: Part B
Intermittent high dose oral afatinib
Drug: Afatinib
160mg for 3 days every 3 weeks
Other Name: Gilotrif




Primary Outcome Measures :
  1. Afatinib concentration in plasma using standard dosing and high intermittent dosing [ Time Frame: Day 1 to Day 29 of drug treatment ]
    To assess the difference in drug ratio from two difference dosing of afatinib

  2. Afatinib concentration in Cerebral Spinal Fluid (CSF) using standard dosing and high intermittent dosing [ Time Frame: Part A: Day 15; Part B: Day 17 and 31 ]
    To assess the difference in drug ratio from two difference dosing of afatinib

  3. Neurological Progression Free Survival [ Time Frame: From time of first study drug administration until first occurrence of disease progression, or death from any cause, up to 2 years ]
  4. Neurological Response Rate [ Time Frame: From time of first study drug administration until first occurrence of disease progression, up to 2 years ]
  5. Overall Survival [ Time Frame: From time of first study drug administration to death from any cause, up to 2 years ]

Secondary Outcome Measures :
  1. Cell-free DNA sequencing of Cerebrospinal Fluid [ Time Frame: From time of first study drug administration to end of study treatment, up to 2 years ]
    To detect EGFR T790M and activating mutation status

  2. European Organization for Research and Treatment of Cancer (EORTC) Quality of Life Questionnaire C30 [ Time Frame: From time of first study drug administration through to end of study treatment or disease progression, up to 2 years ]
    To assess the physical, physiological and social functions. The scale ranges from 1="not all all" to 4-"very much"

  3. EORTC Quality of Life Questionnaire Brain Cancer Module [ Time Frame: From time of first study drug administration through to end of study treatment or disease progression, up to 2 years ]
    To assess future uncertainty, visual disorder, motor dysfunction, and communication deficit. The scale ranges from 1="not all all" to 4-"very much"

  4. Incidences of treatment-emergent adverse events (AE) [ Time Frame: From time of first study drug administration to 28 days after last treatment administration ]
    AEs will be graded according to CTCAE, Version 4.0

  • Performance status of Eastern Cooperative Oncology Group (ECOG) 0-3
  • Adequate organ function

    • Absolute neutrophil count (ANC) ≥1500 / mm3 . (ANC >1000/mm3 may be considered in special circumstances such as benign cyclical neutropenia as judged by the investigator and in discussion with the sponsor).
    • Platelet count ≥75,000 / mm3 .
    • Estimated creatinine clearance > 45ml/min
    • Left ventricular function with resting ejection fraction ≥ 50% or above the institutional Lower Limit of Normal (LLN).
    • Total Bilirubin ≤ 1.5 times upper limit of (institutional/central) normal (Patients with Gilbert's syndrome total bilirubin must be ≤4 times institutional upper limit of normal)
    • Aspartate amino transferase (AST) or alanine amino transferase (ALT) ≤ three times the upper limit of (institutional/central) normal (ULN) (if related to liver metastases ≤ five times ULN).
  • Written informed consent that is consistent with ICH-GCP guidelines

Exclusion Criteria:

  • Symptomatic brain metastases requiring high dose steroids. Patients are excluded from Part A if they develop cerebral manifestation under afatinib. (Those progressing on afatinib will proceed to part B with HDI afatinib)

    • Single dose palliative treatment for symptomatic metastasis outside above allowance to be discussed with sponsor prior to enrolling.
