Assess the Efficacy, Safety and Tolerability of Gefitinib (Iressa® 250mg) as Maintenance Therapy in Locally Advanced or Metastatic (Stage IIIB/IV) Non Small Cell Lung Cancer (NSCLC) (INFORM)
This is a double blind, multicentre, randomized, placebo-controlled study. The eligible patients will be randomized to receive gefitinib or placebo at 1:1 ratio. This study will recruit 296 male or female, histologically or cytologically diagnosed locally advanced or metastatic NSCLC patients with a World Health Organization (WHO) Performance Status (PS) 0-2. Patients must have completed 4 cycles of platinum based first line doublet chemotherapy without experiencing disease progression or unacceptable toxicity. The chemotherapy shall be given every 3 weeks, which includes cisplatin or carboplatin, combined with any one of the following: gemcitabine, paclitaxel, docetaxel, vinorelbine.

|Official Title:||A Placebo-Controlled, Multicentre, Randomised, Parallel Group, Trial to Assess the Efficacy, Safety and Tolerability of Gefitinib (Iressa® 250mg) as Maintenance Therapy in Locally Advanced or Metastatic (StageIIIB/IV) Non Small Cell Lung Cancer (NSCLC) Chinese Patients Who HaveNot Experienced Disease Progression or Unacceptable Toxicity During Front Line Standard Platinum-Based Chemotherapy|
- Progression Free Survival (PFS) [ Time Frame: From date of randomization until the date of first documented progression or date of death from any cause, whichever came first.The primary analysis of PFS will be performed when at least 265 events have occurred, which is expected to occur approximately. ] [ Designated as safety issue: No ]PFS will be calculated from the tumour measurements collected at each tumour assessment per the RECIST criteria and/or the date of patient death. Progression is defined, using RECIST, as a measurable increase in the smallest dimension of any target or non-target lesion, or the appearance of new lesions, since baseline.
- Overall Survival (OS) [ Time Frame: The OS will be assessed from the time of randomization to death from any cause.For patients not known to have died or who have withdrawn from the study for whatever reason,OS will be censored at the last date at which patients were known to be alive. ] [ Designated as safety issue: No ]The OS will be assessed from the time of randomisation to death from any cause. For patients not known to have died(which may include those who have been lost to follow up or who have withdrawn from the study for whatever reason), OS will be censored for the analysis at the last date at which the patients were known to be alive.
- Objective Tumour Response (ORR) [ Time Frame: TTumour assessment using RECIST will be performed at baseline then every 42 days (6 weeks) ± 7 days (1 week) from randomisation until objective progression or death from any cause. ] [ Designated as safety issue: No ]The objective tumour response will be calculated as the number of patients with CR or PR per RECIST Criteria. Complete Response (CR), Disappearance of all target lesions; Partial Response (PR), >=30% decrease in the sum of the longest diameter of target lesions; Overall Response (OR) = CR + PR.
- Disease Control Rate (DCR) [ Time Frame: Tumour assessment using RECIST will be performed at baseline then every 42 days (6 weeks) ± 7 days (1 week) from randomisation until objective progression or death from any cause. ] [ Designated as safety issue: No ]DCR will be calculated as the number of patients with CR, PR or sustained SD≥6 weeks per RECIST Criteria. Complete Response (CR), Disappearance of all target lesions; Partial Response (PR), >=30% decrease in the sum of the longest diameter of target lesions; Stable Disease (SD), Neither sufficient shrinkage to qualify for PR nor sufficient increase
- Symptom Improvement [ Time Frame: at randomization, every 6 weeks until disease progression, and at discontinuation. ] [ Designated as safety issue: No ]Symptom improvement will be assessed from the 7-question Lung Cancer Subscale domain score derived from the FACT-L questionnaire. It is defined as an increase of two or more points on the LCS from randomization, maintained for 21 or more days. It will be calculated as the number of patients analysed with improvement.
- Adverse Event [ Time Frame: AEs and SAEs must be collected from the time that the main study informed consent is obtained to 28 days after discontinuation of study drug. Any ongoing AE or SAE at discontinuation of study treatment and during 28 day follow-up period must be monitored ] [ Designated as safety issue: Yes ]Appropriate description of AEs and laboratory data/vital signs will be produced. Number of patients who had at least one adverse events will be calculated.
