Overview
Brief Summary

Outcomes
Primary Outcomes
Objective Response (OR)
Time Frame: Tumour assessments were performed at screening, week 8, week 16, week 24, and every 8 weeks thereafter.
OR is defined as complete response (CR) and partial response (PR) and was assessed according to the Response Evaluation Criteria in Solid Tumours version 1.0 (RECIST). OR was primary endpoint only for Cohort B.
Clinical Benefit (CB)
Time Frame: Tumour assessments were performed at screening, week 8, week 16, week 24, and every 8 weeks thereafter.
CB was defined as CR, PR or stable disease (SD) for a minimum of 4 months (modified CB) and was assessed according to RECIST 1.0 criteria. CB was primary endpoint only for Cohort A.
Secondary Outcomes
- Overall Survival (OS)(From randomisation to end of follow-up.)
- Best Change From Baseline in ECOG Performance Status(baseline till end of treatment)
- Clinical Benefit (CB)(Tumour assessments were performed at screening, week 8, week 16, week 24, and every 8 weeks thereafter.)
- Significant Change in Cardiac Left Ventricular Ejection Fraction (LVEF)(Baseline and last assessment)
- Time to OR(Tumour assessments were performed at screening, week 8, week 16, week 24, and every 8 weeks thereafter.)
- Duration of OR(Tumour assessments were performed at screening, week 8, week 16, week 24, and every 8 weeks thereafter.)
- Progression-free Survival (PFS)(Tumour assessments were performed at screening, week 8, week 16, week 24, and every 8 weeks thereafter.)
- Pre-dose Concentration of Afatinib in Plasma at Steady State on Day 29 (Cpre,ss,29)(day 29)
