Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This is a multicentre, open-label, uncontrolled, Phase Ib clinical study. Patients who give informed consent will be screened for the study, including genotyping of the tumour and baseline characteristics. Eligible patients will receive a single pre-treatment of low dose of intravenous cyclophosphamide 200 mg/m2 (Day -3). Patients will commence daily oral therapy with the EGFR TKI afatinib as soon as possible, preferably on the same day as low dose cyclophosphamide. Afatinib will be prescribed according to the Summary of Product Characteristics (SmPC) of the product, and will continue in nominal 21-day cycles for as long as clinically indicated. The first day of dosing with EGF-PTI will be designated Day 1.

Immunisation with EGF-PTI will commence 3 days after low dose cyclophosphamide and commencement of EGFR TKI, and will be repeated on Day 14, Day 28, Day 43, and Day 92. After the 5 th vaccination, patients will be followed up every 6 weeks for basic safety data and every 3 months for complete efficacy data, safety data, and maintenance (reduced) doses of EGF-PTI. Patients will continue in the study until disease progression, death, safety concerns (in the opinion of the investigator), non-compliance with the protocol, the patient withdraws from the study, 1 year after randomisation of the last patient, or the study is stopped the sponsor, whichever occurs sooner

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

EGFR-TK Inhibitor plus EGF-PTI

Elegile patients will receive a single pre-treatment low dose of intravenous cyclophosphamide 200mg/m2 before experimental treatment starts. Daily oral therapy with afatinib according to the SmPC of the product in nominal treatment cycles of 21 days followed by immunisation with EGF-PTI.

Group Type EXPERIMENTAL

EGFR-TK Inhibitor

Intervention Type DRUG

Patients will commence daily oral therapy with the EGFR TKI afatinib as soon as possible, preferably on the same day as low dose cyclophosphamide. Afatinib will be prescribed according to the Summary of Product Characteristics (SmPC) of the product, and will continue in nominal 21-day cycles for as long as clinically indicated.

EGF-PTI

Intervention Type BIOLOGICAL

The first day of dosing with EGF-PTI will be designated Day 1. Immunisation with EGF-PTI will commence 3 days after low dose cyclophosphamide and commencement of EGFR TKI, and will be repeated on Day 14, Day 28, Day 43, and Day 92. After the 5

th vaccination, patients will enter a maintenance phase during which reduced dose vaccinations will be performed every 2 or 3 months in conjunction with the interval between detailed check-up of the patient. As this interval can vary between patients, the interval for maintenance vaccination can also vary between 2 and 3 months.

Cyclophosphamide

Intervention Type DRUG

Eligible patients will receive a single pre-treatment of low dose of intravenous cyclophosphamide 200 mg/m2 (Day -3).
