Arms Assigned Interventions
Experimental: Gefitinib and BKM120

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):

  1. A tumour that harbours an EGFR mutation known to be associated with drug sensitivity
  2. 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.

Drug: Gefitinib and BKM120
Dose escalation study of gefitinib and BKM120 with expansion cohort

Detailed Description:

2.1 Primary

• The safety, tolerability and recommended phase 2 dose (RP2D) of the combination of gefitinib and BKM120 will be determined.

2.2 Secondary

  • The pharmacokinetic (PK) profile of gefitinib in combination with BKM120 will be determined.
  • The preliminary anti-tumor activity of gefitinib in combination with BKM120 will be determined.
  • The pharmacodynamic target modulation effects using a hair follicle assay will be determined.

2.3 Exploratory

  • The role of circulating tumour cells as assessed by a microfluidic device will be analyzed and the genetic alterations implicated in lung cancer, including but not limited to EGFR mutations, PI3KCA mutations, PTEN loss will be characterized.
  • The feasibility of detecting somatic mutations from plasma DNA will be ascertained.
