E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To evaluate and explore the activity of lapatinib or placebo in the two treatment groups with respect to the complete response rate (per RECIST) at six months (24 weeks) from chemoradiation completion in subjects with locally advanced SCCHN. |
|
E.2.2 | Secondary objectives of the trial |
To evaluate PFS at 6-months and 1-year, OS, disease-specific survival, loco-regional control & distant relapse, evaluate volumetric tumour responses, determine tolerabilty of the proposed regimen, assess serum concentrations of ErbB1, potentially perform proteomic analysis, determination of intra-tumoural expression of ErbB1, ErbB2, ligands for ErbB receptors and downstream biomarkers |

E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
1. Willing and able to sign a written informed consent; 2. Histologically confirmed diagnosis of SCCHN of one or more of the following sites: oral cavity, oropharynx, hypopharynx and larynx; Multiple primary tumours will: • Have to be histologically proven; • Have to be anatomically distant and surrounded by normal tissue; • Exclude distant metastasis. 3. Prior to enrolment subjects must have ErbB1 over-expression determined by immunohistochemistry (IHC) 3+ as assessed by a central laboratory; 4. Subjects with stage III and IVA/IVB disease, who are to receive cisplatin chemotherapy and radiation therapy as primary treatment (total dose 65 - 70 Gy); • Subjects with any T1 and T2 disease, stage N1, are excluded. • Subjects with distant metastases, ie Stage IVC, are excluded. 5. Willing and able to have a tumour biopsy taken at screening; For patients who have had prior tumour biopsy, an adequate archived specimen must be available. 6. Male or female greater than or equal to 18 years of age; Additional criteria for female subjects or female partners of male subjects are outlined in the protocol. 7. ECOG performance status 0, 1 or 2; 8. Subjects must have adequate haematological, renal and hepatic function as defined in the protcol. 9. Left ventricular ejection fraction (LVEF) within the institutional normal ranges as measured by echocardiogram (ECHO) or Multigated Acquisition (MUGA) scan; 10. Able to swallow tablets whole or swallow a suspension of tablets dissolved in water at study inclusion; •The use and timing of feeding tube is optional. If necessary, the suspension may be administered via percutaneous endoscopic gastrostomy (PEG), percutaneous jejunostomy tube (J- Tube), or a nasogastric tube (NG or Dobhoff type tube). 11. Life expectancy of at least 6 months in the best judgment of the investigator.

E.4 | Principal exclusion criteria |
1. Nasopharyngeal, paranasal sinuses or nasal cavity tumours; 2. Any prior or current treatment for invasive head and neck cancer of any kind. This will include but is not limited to: prior tyrosine kinase inhibitors, prior neoadjuvant therapy, prior surgical resection, or use of any investigational agent; 3. Concurrent use of CYP3A4 inducers or inhibitors. A standard 3-day course of dexamethasone for the prevention of cisplatin-induced nausea and vomiting is permitted; 4. Subjects with known history of uncontrolled or symptomatic angina, arrhythmias, or congestive heart failure; 5. History of another malignancy within the last 5 years, with the exception of completely resected basal or squamous cell skin cancer, or successfully treated in-situ carcinoma. History of non-invasive lesion or in-situ carcinoma, including in the head and neck region that was successfully treated with surgery, photodynamics or laser, will be permitted; 6. Peripheral neuropathy greater than or equal to grade 2; 7. Pregnant or lactating females (female subjects of child-bearing potential will undertake pregnancy testing at screening and during study completion/withdrawal visits); 8. Malabsorption syndrome, disease significantly affecting GI function, that could affect absorption of lapatinib; 9. History of allergic reactions to appropriate antiemetics (e.g. 5-HT3 antagonists) to be administered with platinum chemotherapy; 10. The investigator considers the subject unfit for the study as a result of the medical interview, physical examinations, or screening investigations;
