BIBW 2992 (Afatinib) vs Gemcitabine-cisplatin in 1st Line Non-small Cell Lung Cancer (NSCLC)

The primary endpoint was progression-free survival (PFS) as assessed by central independent review according to Response Evaluation Criteria in Solid Tumours (RECIST) version 1.1. Progression-free survival was defined as the time from randomisation to disease progression or death whichever occurs earlier. A pre-defined set of censoring rules were used for patients who did not have a PFS.

Only data collected up until the analysis cut-off date (27 December 2013) were considered. Median time results from unstratified Kaplan-Meier estimates.

OR is defined as a best overall response of complete response (CR) or partial response (PR) assessed by central independent review according to RECIST version 1.1 and will be presented as the percentage of patients with OR.

CR is defined as the disappearance of all target lesions and non-target lesions and no new lesions.

PR is defined as at least a 30% decrease in the sum of longest diameter (LD) of target lesions taking as reference the baseline sum LD, non-Progressive Disease or non evaluation of all non-target lesions and no new lesions.

(Exact 95% Confidence interval by Clopper and Pearson.)

OS is defined as the time from randomisation to death. For patients who had not died until 7 December 2017, the date they were last known to be alive was derived from patient status records, the trial completion record, radiological imaging assessments, the study treatment termination record, and the randomisation date.

Median time results from unstratified Kaplan-Meier estimates.

OR is defined as a best of overall response of complete response (CR) or partial response (PR) assessed by central independent review according to RECIST version 1.1.

For patients with an objective response, time to objective response was defined as the time from randomisation to the first objective response.

Outcome data are the percentage of patients with OR by each scheduled tumour assessment.

OR is defined as a best of overall response of complete response (CR) or partial response (PR) assessed by central independent review according to RECIST version 1.1.

For patients with an objective response, duration of objective response was defined as the time from the first objective response to disease progression or death whichever occurs earlier. A pre-defined set of censoring rules were used for patients who did not progress/die. The Median values are Kaplan-Meier estimates.

Tumour shrinkage is calculated as the minimum post-baseline sum of longest diameters of target lesions (longest for non-nodal lesions, short axis for nodal lesions) (SLD), as assessed by central independent review. The mean of these minimum values are presented after adjusting for baseline sum of longest diameters and EGFR mutation category. Only data collected up until the analysis cut-off date (27 Dec 2013) were considered. A negative value means the smallest post-baseline SLD was smaller than baseline (decreased since baseline); a positive value means tumor size increased since baseline.

The means are adjusted for baseline sum of lesions and EGFR mutation category.

The last ECOG performance score category recorded during the study. Outcome data are the percentage of patients with an shift of ECOG performance status from baseline to the last ECOG performance status.

ECOG PS measured on 6 point scale to assess participant's performance status. 0=Fully active, able to carry on all pre-disease activities without restriction;

1. Restricted in physically strenuous activity, but ambulatory and able to carry out light or sedentary work;
2. Ambulatory (>50 percent of waking hours), capable of all selfcare, unable to carry out any work activities;
3. Capable of only limited self care, confined to bed or chair more then 50 percent of waking hours;
4. Completely disabled, cannot carry on any selfcare, totally confined to bed or chair;
5. Dead

HRQOL as measured by standardised questionnaires (EuropeanOrganisation for Research and Treatment of Cancer (EORTC)) quality of life questionaires (OLQ-C30) and its lung cancer module (QLQ-LC13). Analysis for cough: QLQ-LC13, question 1.

Time to deterioration was defined as the time from randomisation to a score increase (i.e. worsened) of at least 10 points from baseline (0 to 100 point scale). Patients without deterioration (including those with disease progression) were censored at the date of the last available HRQOL assessment; patients without post-baseline assessments were censored at the date of randomisation. Patients were considered as having deteriorated at the time of death. The median is Kaplan-Meier estimates.

HRQOL as measured by OLQ-C30 and its lung cancer module (QLQ-LC13). Analysis for dyspnoea: composite of QLQ-LC13, questions 3 to 5; individual item from QLQ-C30, question 8.

Time to deterioration was defined as the time from randomisation to a score increase (i.e. worsened) of at least 10 points from baseline (0 to 100 point scale). Patients without deterioration (including those with disease progression) were censored at the date of the last available HRQOL assessment; patients without post-baseline assessments were censored at the date of randomisation. Patients were considered as having deteriorated at the time of death. The median is Kaplan-Meier estimates.

HRQOL as measured by OLQ-C30 and its lung cancer module QLQ-LC13. Analysis for pain: composite of QLQ-C30, questions 9 and 19; individual items from QLQ-LC13, questions 10, 11 and 12.

Time to deterioration was defined as the time from randomisation to a score increase (i.e. worsened) of at least 10 points from baseline (0 to 100 point scale). Patients without deterioration (including those with disease progression) were censored at the date of the last available HRQOL assessment; patients without post-baseline assessments were censored at the date of randomisation. Patients were considered as having deteriorated at the time of death. The median is Kaplan-Meier estimates.

Outcome data presented are the percentage of patients by worst CTCAE grade (only Grades 2 to 4 presented) on treatment for the following laboratory parameters: Potassium, Aspartate Aminotransferase (AST), Alanine Aminotransferase (ALT), Creatine and Creatine Kinase.

For Potassium; only CTCAE grades resulting from hypokalemia (low values) are presented.
