Trial Outcomes & Findings for 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) (NCT NCT00770588)

NCT ID: NCT00770588

Last Updated: 2016-02-08

Results Overview

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.

Recruitment status

COMPLETED

Study phase

PHASE4

Target enrollment

296 participants

Primary outcome timeframe

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.

Timeframe: 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will be assessed from the time of randomization to death from any cause.For patients not known to have died or who have withdrawn from the study for whatever reason,OS will be censored at the last date at which patients were known to be alive.

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 For patients not known to have died(which may include those who have been lost to follow up or who have withdrawn from the study for whatever reason), OS will be censored for the analysis at the last date at which the patients were known to be alive.

SECONDARY outcome

Timeframe: 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.

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.

SECONDARY outcome

Timeframe: 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.

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

Outcome measures

Outcome data not reported

SECONDARY outcome

Timeframe: at randomization, every 6 weeks until disease progression, and at discontinuation.

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.

SECONDARY outcome

Timeframe: 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

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.
