MEDI4736 (Anti PD-L1) Combined With Gefitinib in Subjects With Non-Small Cell Lung Cancer(NSCLC).

A Phase I, Open-Label, Multicentre Study to Assess the Safety, Tolerability, Pharmacokinetics and Preliminary Anti-tumour Activity of Gefitinib in Combination With MEDI4736 (Anti PD-L1) in Subjects With Non-Small Cell Lung Cancer(NSCLC)

This a Phase I, Open-Label, Multicentre Study to assess the safety, tolerability, pharmacokinetics and preliminary anti-tumour activity of gefitinib in combination with MEDI4736 (anti PD-L1) in Subjects with Non-small cell lung cancer (NSCLC). The study consists of two phases: Escalation phase and an expansion phase to be conducted in locally advanced or metastatic NSCLC subjects

In Escalation phase: MEDI4736 and gefitinib in NSCLC subjects In Expansion phase: Subjects with EGFR mutation positive locally advanced or metastatic NSCLC will be enrolled in expansion arms. Initiation of expansion arms with the recommended dose of MEDI4736 in combination with gefitinib will be based on an adequate safety and tolerability profile of the combination from the escalation phase.

Key Inclusion Criteria:

1. Provision of signed and dated, written informed consent

2. Male or female aged 18 years and older.

3. Subjects must have a. In the escalation phase, locally advanced or metastatic NSCLC subjects who have either failed to respond or relapsed following any line of standard treatment, were unable to tolerate, or were not eligible for standard treatment b. In the expansion phase, histologically or cytologically confirmed locally advanced or metastatic NSCLC that is EGFR mutation positive, naïve to EGFR TKI therapy, and sensitive to EGFR TKIs therapy

4. a.For Escalation Phase: At least one lesion (measurable and/or non-measurable) b.For Expansion Phase: At least one measurable lesion.

5. Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1.

   • For Japan Escalation - the same as the global escalation I/E criteria except patients must be EGFR mutation positive

Key Exclusion Criteria:

1. Any concurrent chemotherapy, immunotherapy, biologic, or hormonal therapy for cancer treatment.
2. Any investigational agent, chemotherapy, immunotherapy, biologic, hormonal within 28 days of the first dose of study treatment
3. Inadequate bone marrow reserve or organ function
