Afatinib is approved therapy for SCC of the lung after progression with standard of care chemotherapy. There is also evidence of improvement of progression free survival of patients with metastatic/recurrent SCC of the head and neck after failure of chemotherapy in patients treated with afatinib. Therefore, treatment of patients with these 2 conditions with afatinib is not experimental, and will follow conventional clinical management.

Phase 2
| Drug | Synonyms | Arms |
|---|---|---|
| Afatinib | Patients genotyped positive for MET-N375S polymorphism |
Clinical objectives:
1. To determine the efficacy of afatinib in patients with germline MET-N375S polymorphism.
2. To determine the tolerability of afatinib in chemo-relapsed patients with germline
MET-N375S polymorphism.
Research objectives:
1. To determine the prevalence of MET and TP53 mutations, as well as HER2 and MET
amplification, in various cancers, particularly head and neck cancers and lung cancers.
2. To establish tumour cell lines, spheroids of xenografts for drug screening.
Endpoints of study:
1. To determine the response rate of SCC HN/lung with Met-N375S to afatinib.
2. The secondary endpoints include progression-free survival and toxicity.
3. Frequency of MET mutations and TP53 mutations in patients with cancer.

lung or head and neck region, and has failed standard treatment.
3. No other active malignancy within the past 24 months
4. All subjects must have at least one tumour lesion (primary or metastatic) that is
suitable for free-hand or image-guided biopsy at baseline.
5. Clinical study will enroll patients genotyped positive for MET-N375S
polymorphism.

adequate contraception. Women of childbearing potential must have a pregnancy test
performed a maximum of 7 days before start of study medication, and a negative result
must be documented before start of study medication. Women of childbearing potential
and men, must agree to use adequate contraception (barrier method of birth control)
upon signing the informed consent form until at least 3 months after the last study
drug administration 4. Known or suspected allergy to the investigational agent or any
agent given in association with this study.

being evaluated in this study 6. Patients with CTCAE Grade 2 or higher peripheral
neuropathy. 7. History of significant cardiac disease: congestive cardiac failure >
NYHA class II, ongoing unstable angina, new-onset angina or myocardial infarction
