Study Design

Endpoint classification safety/efficacy study
Intervention model single group assignment
Masking open label
Primary purpose treatment
Patients with NSCLC who progress on treatment with single-agent EGFR TKI (e.g., gefitinib or erlotinib), and meet the clinical definition of EGFR TKI resistance (Jackman et al., 2010): A tumour that harbours an EGFR mutation known to be associated with drug sensitivity Previous objective clinical benefit from treatment with an EGFR TKI Patients should have systemic progression of disease (by RECIST) while on continuous treatment with gefitinib or erlotinib. Patients that have previously progressed on EGFR TKI (not in the preceding line of treatment) may also be enrolled and will receive gefitinib and BKM120 sequentially. Patients with any solid tumour-type and "activated" PI3 kinase pathway and historically known to over express EGFR may also be recruited. Once the RP2D is reached, an expansion cohort of 40 patients will be accrued for extended safety experience and to ascertain preliminary activity.

CTCAE grade 3 anxiety iii. meets the cut-off score of 10 in the PHQ-9 or a cut-off of 15 in the GAD-7 mood scale, respectively, will be excluded from the study unless overruled by the psychiatric assessment. iv. selects a positive response of '1, 2, or 3' to question number 9 regarding potential for suicidal thoughts ideation in the PHQ-9 (independent of the total score of the PHQ-9) Note: The psychiatric judgment overrules the mood assessment questionnaire result/investigators judgment. 6. Patients with diarrhea < CTCAE grade 2 7. Any of the following concurrent severe and/or uncontrolled medical conditions which could compromise participation in the study: i. ST depression or elevation of < 1.5 mm in 2 or more leads ii. Congenital long QT syndrome iii. History or presence of ventricular arrhythmias or atrial fibrillation iv.
