necitumumab pemetrexed cisplatin ...Study Participants
633The research study is testing the investigational drug necitumumab in the treatment of advanced non-small cell lung cancer. The aim of this study is to determine if necitumumab, given together with a standard chemotherapy combination consisting of cisplatin and pemetrexed will be more effective in improving participant disease than the standard chemotherapy combination alone.
Multinational, randomized, multicenter, open-label Phase 3 study of 633 participants with advanced, nonsquamous (Stage IV) NSCLC. Participants will be randomized on a 1:1 basis to receive first-line necitumumab plus chemotherapy consisting of pemetrexed and cisplatin in study Arm A, or first-line pemetrexed-cisplatin chemotherapy alone in Arm B.
Baseline radiographic assessment of disease will be performed within 21 days prior to randomization (first treatment will be administered within 7 days following randomization).
Participants will undergo radiographic assessment (computed tomography or magnetic resonance imaging) of disease status every 6 weeks (± 3 days), until there is radiographic documentation of progressive disease (PD). Chemotherapy will continue for a maximum of six cycles in each arm (Or until there is radiographic documentation of PD, toxicity requiring cessation, protocol noncompliance or withdrawal of consent); participants in Arm A only will continue to receive necitumumab until there is radiographic documentation of PD, toxicity requiring cessation, protocol noncompliance, or withdrawal of consent.
After the end-of-study-visit (following PD), follow-up information regarding further anticancer treatment and survival will be collected every 2 months (± 7 days). For participants who discontinue study for reasons other than PD (eg, symptomatic deterioration), information on disease progression will also be collected until PD is documented. Follow-up will continue as long as the participant is alive, or until the end of the trial.
500 milligram per square meter (mg/m2) administered Intravenously (I.V.) on Day 1 of every 3-week cycle, for a maximum of six cycles
75 mg/m2 administered I.V. on Day 1 of every 3-week cycle, for a maximum of six cycles
800 mg (absolute dose) on Days 1 and 8 of every 3-week cycle, administered as an I.V.

OS is defined as the time from randomization to death from any cause. Participants who do not die at the end of the extended follow-up period, or were lost to follow-up during the study, were censored at the last date they were known to be alive. OS was estimated using the Kaplan-Meier method.
PFS is defined as the time from randomization until the first radiographic documentation of measured progressive disease as defined by RECIST (Version 1.0), or death from any cause. Participants who die without a reported prior progression will be considered to have progressed on the day of their death. Participants who did not progress or were lost to follow-up were censored at the day of their last radiographic tumor assessment. If no baseline or postbaseline radiologic assessment was available, the participant was censored at the date of randomization. If death or PD occurs after two or more consecutive missing radiographic visits, censoring occurred at the date of the last radiographic visit prior to the missed visits.
ORR is confirmed best overall tumor response of CR or PR. According to RECIST v1.0, 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.
TTF was defined as the time from study enrollment/randomization to the first observation of measured progressive disease, death from any cause, or early discontinuation of treatment or initiation of new anti-cancer therapies. Response was defined using Response Evaluation Criteria In Solid Tumors (RECIST, version 1.0) criteria. Progressive Disease (PD) was defined as having at least a 20% increase in sum of longest diameter of target lesions. Time to treatment failure was censored at the date of the last follow-up visit for participants who did not discontinue early, who were still alive, and who have not progressed.
The EQ-5D is a generic, multidimensional, health-related, quality-of-life instrument. The profile allows participants to rate their health state in 5 health domains: mobility, self-care, usual activities, pain/discomfort, and anxiety/depression using a three level scale 1-3 (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).
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. Scores for each of the reported categories ranged from 0 (for best outcome) to 100 (for worst outcome). 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.
EGFR IHC H-score = weighted sum of % 1+ cells, twice % 2+ cells, and three times % 3+ cells. IHC H-score criteria assesses participants with a low EGFR expression defined by a H-score cutoff value of < 200 and participants with a high EGFR expression defined by a H-score of cutoff value of >=200.
A participant was considered to have an anti-Necitumumab antibody response if anti-drug antibodies (ADA) were confirmed positive. Treatment emergent antibodies were defined as any anti-Necitumumab antibody titer equal to or greater than 4-fold the participant's baseline titer.
EGFR IHC H-score = weighted sum of % 1+ cells, twice % 2+ cells, and three times % 3+ cells. IHC H-score criteria assesses participants with a low EGFR expression defined by a H-score cutoff value of < 200 and participants with a high EGFR expression defined by a H-score of cutoff value of >=200.
