Trial Outcomes & Findings for A Study of Chemotherapy and Ramucirumab Versus Chemotherapy Alone in Second Line Non-Small Cell Lung Cancer (NSCLC) Participants Who Received Prior First Line Platinum-based Chemotherapy (NCT NCT01168973)

Participants who died, due to any cause, or were alive at the end of the study but off study drug were considered to have completed the study.

A Study of Chemotherapy and Ramucirumab Versus Chemotherapy Alone in Second Line Non-Small Cell Lung Cancer (NSCLC) Participants Who Received Prior First Line Platinum-based Chemotherapy

Overall survival was the time from randomization until the date of death from any cause. Participants who were alive at the end of the follow-up period (or lost to follow-up) were censored on the last date the participant was known to be alive.

PFS time was the time from randomization until the date of objectively determined progressive disease (PD) or death due to any cause, whichever occurred first. According to Response Evaluation Criteria in Solid Tumors version 1.1 (RECIST v1.1), PD was at least a 20% increase in the sum of the diameters of target lesions, taking as reference the smallest sum on study. In addition to the 20% relative increase, the sum must have also demonstrated an absolute increase of at least 5 millimeters (mm). The appearance of 1 or more new lesions and/or unequivocal progression of existing nontarget lesions was also considered progression. Participants without objectively determined PD who were alive at the end of the follow-up period (or lost to follow-up) were censored on the date of the participant's last complete radiographic tumor assessment; if no baseline or post-baseline radiologic assessment was available, the participant was censored at the date of randomization.

Participants achieved an objective response if they had a best overall response of partial response (PR) or complete response (CR). According to RECIST v1.1, 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; 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 \[if tumor markers were initially above the upper limit of normal (ULN)\]. The percentage of participants who achieved an objective response=(number of participants with CR or PR)/(number of participants assessed)\*100.

Participants achieved disease control if they had a best overall response of PR, CR or stable disease (SD). According to RECIST v1.1, 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; 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 ULN). 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=(number of participants with CR, PR, or SD)/(number of participants assessed)\*100.

The LCSS consisted of 9 items: 6 items focused on lung cancer symptoms \[loss of appetite, fatigue, cough, dyspnea (shortness of breath), hemoptysis (blood in sputum), and pain\] and 3 items were global items (symptom distress, interference with activity level, and global quality of life). Participant responses to each item were measured using visual analogue scales (VAS) with 100-mm lines. A higher score for any item represented a higher level of symptoms/problems. The Average Symptom Burden Index (ASBI) was the mean of the 6 symptom items of the LCSS, and the Total LCSS was the mean of all 9 LCSS items. ASBI and Total LCSS were not computed for a participant if he/she had 1 or more missing values for the 6 and 9 items, respectively. Maximum improvement in LCSS scores, ASBI, and Total LCSS score was the largest decrease from baseline for each variable, which was the smallest (most negative or smallest positive) non-missing value among all change from baseline values for each variable.

The EQ-5D is a quality-of-life instrument that consists of 2 parts. The first part (Health State Index score) allowed participants to rate their health state in 5 health domains: mobility, self-care, usual activities, pain/discomfort, and anxiety/depression using a scale from 1 to 3 (no problem, some problems, and extreme problems, respectively). These combinations of attributes were converted into a weighted Health State Index score according to a United Kingdom population-based algorithm; the possible values for the Health State Index score ranged from -0.59 (severe problems in all 5 dimensions) to 1.0 (no problem in any dimension). The second part of the EQ-5D was a VAS that allowed participants to rate their present health condition. Possible EQ-5D VAS scores ranged from 0 (worst imaginable health state) to 100 (best imaginable health state).

The number of participants who had treatment-emergent or follow-up emergent anti-drug antibodies (ADA) is reported. Participants with treatment-emergent ADA were defined as participants who had any sample from baseline through Cycle 5 pre-infusion that was a 4-fold increase (2 dilution increase) in immunogenicity titer over the baseline titer, or participants who tested negative at baseline and positive post-baseline (at titer of ≥1:20). Participants with follow-up emergent ADA were defined as participants who had any sample during 30 days post last infusion that was a 4-fold increase (2 dilution increase) in immunogenicity titer over the baseline titer.

Data presented are the number of participants who experienced at least 1 TEAE, Grade 3, 4, or 5 TEAE, treatment-emergent serious adverse event (SAE), TEAE leading to discontinuation of study treatment (ramucirumab/placebo or docetaxel), and TEAE leading to death. Clinically significant events were defined as treatment-emergent SAEs and other non-serious adverse events (AEs) regardless of causality. A summary of SAEs and other non-serious AEs, regardless of causality, is located in the Reported Adverse Events module.
