A Study of Emibetuzumab in Non Small Cell Lung Cancer (NSCLC) Participants

ORR is confirmed best overall tumor response of CR or PR. According to RECIST v1.1, CR was defined as the disappearance of all target and non-target lesions; PR defined as a >30% decrease in the sum of the longest diameters (LD) of the target lesions, taking as reference the baseline sum of the LD. Percentage of participants was calculated as: (total number of participants with CR or PR from start of the treatment until disease progression or recurrence)/total number of participants treated) * 100.

PFS defined as date of randomization until the date of objectively determined progression defined by Response Evaluation Criteria in Solid Tumors criteria or death from any cause, whichever is first.

Progressive disease (PD) defined as ≥20% increase in sum of diameter of target lesion with the sum demonstrating an increase of ≥5 mm; appearance of ≥1 new lesions or unequivocal progression of non- target lesions. Participants with no baseline disease assessment were censored at randomization date, regardless of whether or not objectively determined PD or death was observed; participants not known to have died or to have objective progression as of data inclusion cutoff were censored at last post baseline radiological assessment date or randomization date, if there was no post baseline radiological assessment.

Zero participants analyzed. CTS data was not collected for analysis due to N=0 CR and N=3 PR.

Participants achieved disease control if they had a best overall response of PR, CR or SD. According to RECIST v1.1, CR was the disappearance of all non-nodal target lesions, with the short axes of any target lymph node reduced to <10 mm, the disappearance of all nontarget lesions, and the normalization of tumor marker levels (if tumor markers were initially above the upper limit of normal [ULN]); PR was defined as at least a 30% decrease in the sum of the diameters of target lesions (including the short axes of any target lymph node), taking as reference the baseline sum diameter. SD was neither sufficient shrinkage to qualify as PR nor sufficient increase to qualify as PD, taking as reference the smallest sum diameter since treatment started. The percentage of participants who achieved disease control equals (number of participants with CR, PR, or SD)/(number of participants assessed)*100.

Zero participants analyzed. Duration of Response for CR and PR data was not collected for analysis due to N=0 CR and N=3 PR.

OS was defined as duration from the date of study enrollment to the date of death from any cause. Participants not known to have died as of the data inclusion cut-off date were censored at the date of last contact. The last contact for participants in post-discontinuation was the last date participant was known to be alive.

EORTC QLQ-C30 v3.0 is a self-administered questionnaire with multidimensional scales that measures 5 functional domains (physical, role, cognitive, emotional, and social), global health status, and symptom scales of fatigue, pain, nausea and vomiting, dyspnea, loss of appetite, insomnia, constipation and diarrhea, and financial difficulties. A linear transformation is applied to standardize the raw scores to range between 0 and 100 per developer guidelines. For functional domains and global health status, higher scores represent a better level of functioning. For symptoms scales, higher scores represented a greater degree of symptoms.

The EORTC lung module QLQ-LC13 comprises 13 items consisting of one multi-item scale to assess dyspnea and a series of single-item measures assessing pain, coughing, sore mouth, dysphagia, peripheral neuropathy, alopecia, and hemoptysis. A linear transformation is applied to standardize the raw scores to range between 0 and 100 per developer guidelines. The higher scores represent a greater degree of symptoms.

The EQ-5D is a generic, multidimensional, health status instrument. The profile allows participants to rate their health state in 5 health domains: mobility, self-care, usual activities, pain/discomfort, and mood using a 3-level scale (no problem, some problems, and major problems). These combinations of attributes were converted into a weighted health-state Index Score according to the United Kingdom (UK) population-based algorithm. The possible values for the Index Score ranged from -0.59 (severe problems in all 5 dimensions) to 1.0 (no problem in any dimension). A negative change indicated a worsening of the participant's health status.

Additionally, participants will indicate their current health status by marking on a continuum ranging from 100 (best imaginable health state) to 0 (worst imaginable health state).

AUC(0-tlast) = area under the concentration versus time curve from time zero through the last quantifiable sample.
