Iressa v BSC (Best Supportive Care) in First Line NSCLC
INSTEP
A Phase II Multicentre Randomised, Parallel Group, Double-Blind, Placebo-Controlled Study of ZD1839 (IRESSATM) (250MG Tablet) Plus Best Supportive Care (BSC) Versus Placebo Plus BSC in Chemotherapy-Naive Patients With Advanced (Stage IIIB or IV) Non-Small Cell Lung Cancer (NSCLC) and Poor Performance Status

Brief Summary
The purpose of the study is to determine if the addition of Iressa to Best Supportive Care treatment will increase the progression free survival of chemo-naïve, poor performance status patients, with stage IIIB or IV NSCLC.

Conditions
Outcome Measures
Primary Outcomes (1)
To compare Iressa v best supportive care in terms of progression free survival
Progression-free survival
Secondary Outcomes (4)
To compare Iressa v best supportive care in terms of objective tumour response rate
Overall objective tumour response rate (CR and PR) according to the RECIST criteria
To compare Iressa v best supportive care in terms of overall survival
Time to death
To compare Iressa v best supportive care in terms of quality of life
Improvement in patient-reported functionality as measured by trial outcome index, comprised of the physical and functional well being sections and LCS of FACT-L and quality of life measured by the FACT-L total score
To compare Iressa v best supportive care in terms of tolerability
Adverse event profile (type, frequency and severity of adverse events); laboratory parameters and vital signs
Other Outcomes (3)
To investigate the correlation of the expression of biomarkers in tumour tissue obtained prior to gefitinib therapy with gefitinib clinical efficacy and to determine a set of biomarkers to enable patient selection for therapy.
Efficacy (objective response rate and progression free survival), toxicity, EGFR signalling pathways markers, RNA expression profile, gene polymorphisms of pre specified germline and tumour genes, DNA methylation, plasma and urine proteomics
To compare gefitinib + BSC versus Placebo + BSC in terms of Health Resource Utilisation
The use of selected items of resource and concomitant medications including: number of in patient days, number of out patient visits, number of invasive procedures, pallative radiotherapy, concomitant medications.
To compare gefitinib + BSC versus Placebo + BSC in terms of changes in pain and fatigue
Changes in pain and fatigue as measured by the single items from the FACT-L physical well being domain.
