|
MedDRA Classification |
E.1.3 | Condition being studied is a rare disease | Yes |
E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The primary objective of the study is to assess the additive effect of ZD1839 250 mg and ZD1839 500 mg (given either concomitantly or as maintenance) over cisplatin plus radiotherapy (RT) in terms of local disease control (progression-free) rate at 2 years. |
|
E.2.2 | Secondary objectives of the trial |
Comparing ZD1839 250 mg and ZD1839 500 mg or placebo:
1. used continuously (concomitantly and for maintenance) with cisplatin plus radiotherapy (RT) in terms of local disease control (progression-free) rate at 2 years. 2. used either concomitantly alone or continuously with cisplatin plus radiotherapy (RT) in terms of local disease control (progression-free) rate at 1 year. 3. used either concomitantly alone or continuously with cisplatin plus radiotherapy (RT) in terms of complete response (CR). 4. used either concomitantly alone or continuously with cisplatin plus radiotherapy (RT) in terms of progression-free survival (PFS). 5. used either concomitantly alone or continuously with cisplatin plus radiotherapy (RT) in terms of safety & tolerability. 6. used either concomitantly alone or continuously with cisplatin plus radiotherapy (RT) in terms of overall survival.
