TIDAL1: Feasibility Study to Estimate Number of Patients With Precancerous Areas in Their Airways and the Response to Gefitinib
Study Details
Study Description
Brief Summary
We are going to use a special type of bronchoscopy test to examine patients who have had previous surgical treatment for lung cancer or head and neck cancer. The aim is to determine
- whether we can identify precancerous changes in their airways b) whether this type of testing is acceptable and c) get an initial idea of whether a new drug called gefitinib has any effect on precancerous areas in the airway.

Outcome Measures
Primary Outcome Measures
- Incidence of high grade dysplasia of the bronchial epithelium in patients at high risk of lung dysplasia [during the screening broncoscopy - carried out within the first month post consent]
Patients will have white/blue light bronchoscopy with biopsy of identified lesions. The incidence of high grade lung epithelial dysplasia will be recorded.
Secondary Outcome Measures
- Acceptability of screening patients as measured by success of trial recruitment [12 months]
- Response of high grade dysplasia to treatment (complete / partial / stable / progression) [6 & 12 months]
To be estimated by photography & biopsy of the lesions & comparison with previous findings: Complete response: Complete resolution of a dysplastic lesion Partial response: Reduction of a dysplastic lesion by >=50% OR Reduction in grade of a high grade dysplastic lesion Progressive disease: Development of a new area of high grade dysplasia or invasive malignancy in an area of previous low grade dysplasia or normal epithelium OR Development of a higher grade lesion in an area of previous high grade dysplasia OR Increase in surface area of >=50%. Stable disease: None of the above.
- Toxicity and acceptability of treatment (proportion of patients refusing study entry). [2 weeks, 4 weeks, 3 & 6 months]
- Successful biobanking of samples [12 months]

-
Evidence of severe or uncontrolled systemic disease or psychiatric disorder that would interfere with the patient's safety
-
Known severe hypersensitivity to Gefitinib or any of the excipients of the product
-

History of allergy to contrast medium
-
Insufficient lung function as determined by either clinical examination or an arterial oxygen tension (PaO2) of < 9.3kpa
-
Inability to swallow oral medications
-
Presence of active inflammatory bowel disease, partial or complete bowel obstruction or chronic diarrhoea or any condition which would interfere with absorption of an oral drug.
