Phase 2
Completed
Conditions
Esophageal Cancer
Gastric Cancer

Registration Number
NCT00215644
Lead Sponsor

Primary Outcome Measures
NameTimeMethod
Percentage of Participants With Objective Response Assessed by Independent Review CommitteeBaseline up to PD or death due to any cause (up to approximately 3 years)

Objective response was defined as having a complete response (CR) or a partial response (PR). Response assessment was performed using modified World Health Organization (WHO) criteria. CR: disappearance of all index and non-index lesions, without appearance of any new lesion. PR: greater than (\>) 50 percent (%) decrease from baseline in sum of product of diameters of index lesions, without appearance of any new lesion.

Secondary Outcome Measures
NameTimeMethod
Duration of Objective Response Assessed by Independent Review CommitteeFrom first documented objective response to PD or death due to any cause (up to approximately 3 years)

Objective response was defined as having a CR or a PR. Response assessment was performed using modified WHO criteria. CR: disappearance of all index and non-index lesions, without appearance of any new lesion. PR: \>50% decrease from baseline in sum of product of diameters of index lesions, without appearance of any new lesion. Duration of objective response was defined as time from first appearance of CR or PR to time of PD (PD: \>25% increase in one or more lesions, or appearance new lesions) or death. Duration of objective response was to be assessed using Kaplan-Meier analysis.

Protein Biomarkers LevelsBaseline up to approximately 3 years
Percentage of Participants With Anti-Matuzumab AntibodiesBaseline up to approximately 3 years
Matuzumab Serum ConcentrationBaseline up to approximately 3 years
Progression-Free SurvivalBaseline up to PD or death due to any cause (up to approximately 3 years)

PFS was defined as the time from randomization to the first documentation of PD or to death due to any cause, whichever occurred first. PD: \>25% increase in one or more lesions, or appearance new lesions. PFS was estimated using Kaplan-Meier analysis.

Overall Survival (OS)Baseline until death due to any cause (up to approximately 3 years)

OS was defined as the duration from randomization to death (due to any cause). OS was estimated using Kaplan-Meier analysis.

Best Overall Change From Baseline in European Organization for Research and Treatment of Cancer Quality-of-Life Questionnaire-Core 30 (EORTC QLQ-C30) Global Health Status (GHS)/Quality of Life (QoL) ScoreBaseline (Day 1), Post Baseline (Up to 3 Years)

EORTC QLQ-C30 included GHS/QoL, functional scales (physical, role, cognitive, emotional, social), symptom scales (fatigue, pain, nausea/vomiting), and single items (dyspnea, appetite loss, insomnia, constipation, diarrhea, financial difficulties). Most questions from EORTC QLQ-C30 were a 4-point scale (1/Not at All to 4/Very Much), except Items 29-30, which comprise GHS scale and were a 7-point scale (1/Very Poor to 7/Excellent). For this instrument, GHS/QOL was linearly transformed and ranged 0-100, where lower scores indicate poorer functioning (e.g., worsening) and higher scores indicate better functioning (e.g., improvement). EORTC QLQ-C30 GHS/QoL score at baseline and best overall change from baseline (throughout study) are reported.
