  Purpose

This is an international multi-center trial that will enroll patients with locally advanced, unresectable, or metastatic gastric, esophageal, or gastro-esophageal junction cancer whose tumors have amplification of the ErbB2 (HER2) gene. The trial will investigate whether lapatinib, when added to the chemotherapy regimen, capecitabine plus oxaliplatin (CapeOx), extends the time to progression and overall survival. Tumor ErbB2 (HER2) status must be known before trial entry. CapeOx is administered to all patients, and patients will be randomly assigned to receive either lapatinib or placebo.

Primary Outcome Measures:
  • Overall Survival [ Time Frame: From randomization until death due to any cause (average of 51 weeks) ] [ Designated as safety issue: No ]
    Overall Survival is defined as the time from randomization until death due to any cause. Participants who had not died were censored at the follow-up visit as either follow-up ended or follow-up ongoing.

  • Overall Survival in All Randomized Participants [ Time Frame: From randomization until death due to any cause (average of 51 weeks) ] [ Designated as safety issue: No ]
    Overall Survival is defined as the time from randomization until death due to any cause. Participants who had not died were censored at the follow-up visit as either follow-up ended or follow-up ongoing.


Secondary Outcome Measures:
  • Progression Free Survival (PFS) [ Time Frame: From randomization until the earliest date of disease progression or death due to any cause (average of 30 weeks) ] [ Designated as safety issue: No ]
    PFS is defined as the interval between the date of randomization and the earliest date of disease progression (PD) or death due to any cause. Per Response Evaluation Criteria in Solid Tumors (RECIST) version 1.0, PD is defined as at least a 20% increase in the sum of the diameters of target lesions, taking as a reference, the smallest sum of diameters recorded since the treatment started or the appearance of >= 1 new lesion. Participants who did not have a radiological assessed PD but had symptomatic PD were also counted. Participants who had neither progressed nor died were censored at the follow-up visit as either follow-up ended or follow-up ongoing. Participants who received non-study anti-cancer therapies before disease progression were treated as censored.

  • Number of Participants With a Response of Confirmed Complete Response (CR) or Confirmed Partial Response (PR) [ Time Frame: From randomization until the date of the first documented response of CR or PR (average of 9 weeks) ] [ Designated as safety issue: No ]
    A participant was defined as a responder if he/she achieved either a CR (the disappearance of all target and non-target lesions) or a PR (at least a 30% decrease in the sum of the longest diameters [LD] of target lesions, taking as a reference the Baseline sum LD) as assessed by the investigator (confirmed by radiographic imaging within 4 weeks from initial observations).

  • Number of Participants With Clinical Benefit (CB) [ Time Frame: From randomization until disease progression (PD) or death due to any cause (average of 30 weeks) ] [ Designated as safety issue: No ]
    CB is defined as evidence of a CR (disappearance of all target and non-target lesions) or PR (at least a 30% decrease in the sum of the LD of target lesions, taking as a reference the Baseline sum LD) at any time or stable disease (SD, neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for PD, taking as reference the smallest sum LD since the treatment started) as assessed by the investigator.

  • Time to Response (TTR) [ Time Frame: From Baseline (Day 1) until the first documented evidence of confirmed CR or PR (average of 9 weeks) ] [ Designated as safety issue: No ]
    TTR is defined as the time from randomization until the date of the first documented evidence of CR (the disappearance if all target and non-target lesions) or PR (at least a 30% decrease in the sum of the LD of target lesions, taking a reference the Baseline sum LD) as assessed by the investigator.

  • Duration of Response (DOR) [ Time Frame: From the time of the first documented evidence of a confirmed CR or PR until the earliest date of disease progression or death due to any cause (average of 36 weeks) ] [ Designated as safety issue: No ]
    DOR is defined as the time from the first documented evidence of a CR (the disappearance of all target and non-target lesions) or PR (at least a 30% decrease in the sum of the LD of target lesions, taking as a reference the Baseline sum LD) until the first documented sign of PD or death due to any cause. Per RECIST, PD is defined as at least a 20% increase in the sum of the diameters of target lesions, taking as a reference, the smallest sum of diameters recorded since the treatment started or the appearance of >=1 new lesion. Participants who had neither progressed nor died were censored at the follow-up visit as either follow-up ended or follow-up ongoing. Participants who received non-study anti-cancer therapies before disease progression were treated as censored.

  • Number of Participants With Any Non-serious Adverse Event (AE: Occurring in >=5% Participants in Any Treatment Arm) or Any Serious Adverse Event (SAE) [ Time Frame: From the first dose of study medication until 30 days after the last dose (average of 229 days) ] [ Designated as safety issue: No ]
    An AE is defined as any untoward medical occurrence in a participant or clinical investigation participant, temporally associated with the use of a medicinal product, whether or not considered related to the medicinal product. An AE can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease (new or exacerbated) temporally associated with the use of a medicinal product. An SAE is defined as any untoward medical occurrence that, at any dose, results in death, is life threatening, requires hospitalization or prolongation of existing hospitalization, results in disability/incapacity, is a congenital anomaly/birth defect, or is an event of possible drug-induced liver injury. Refer to the general Adverse AE/SAE module for a complete list of AEs and SAEs.

  • Number of Participants With Adverse Events of the Indicated Severity, Per the National Cancer Institute (NCI) Common Terminology Criteria in Adverse Events (CTCAE) [ Time Frame: From the first dose of study medication until 30 days after the last dose (average of 229 days) ] [ Designated as safety issue: No ]
    An AE is defined as any untoward medical occurrence in a participant or clinical investigation participant, temporally associated with the use of a medicinal product, whether or not considered related to the medicinal product. An AE can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease (new or exacerbated) temporally associated with the use of a medicinal product. An SAE is defined as any untoward medical occurrence that, at any dose, results in death, is life threatening, requires hospitalization or prolongation of existing hospitalization, results in disability/incapacity, is a congenital anomaly/birth defect, or is an event of possible drug-induced liver injury. AE/SAE severity was graded according to NCI CTCAE, version 3.0: Grade (G) 1, mild; G2, moderate; G3, severe; G4, life threatening; G5, death related to toxicity.

  • Mean Change in Scores on the European Organization for Research and Treatment of Cancer (EORTC) Quality of Life (QOL) Questionnaire Core 30 (QLQ-C30) From Baseline to Week 36 [ Time Frame: From Baseline (Day1) to Week 36 ] [ Designated as safety issue: No ]
    The QLQ-C30, a self administered tool used to assess HROL, consists of 30 items that assesses 15 domains consisting of 5 functional scales (s.) (physical, role, emotional, cognitive, social) and nine symptom s. or single items (fatigue, nausea and vomiting, pain, dyspnea, insomnia, appetite loss, constipation, diarrhea, financial difficulties) and a global health status or QOL s.. For the functional s. and symptom s. or single items, participants assessed using a 4-point s. (1=not at all; 2=a little; 3=quite a bit; 4=very much), whereas global health status or QOL was assessed using a 7-item Likert s., ranging from "poor" to "excellent." All s. and single-item scores ranged from 0 to 100. For the functional scores, a higher score indicated a better HRQOL, i.e. 0=worst HRQOL, 100=best HRQOL; for the symptom s. or single items , a higher score indicated a high level of symptoms and problems, i.e. 0=no symptoms, 100=most severe symptoms.

  • Mean Change in Scores on the EORTC Quality of Life (QOL) Questionnaire of Stomach 22 (QLQ-STO22) From Baseline to Week 36 [ Time Frame: From Baseline (Day1) to Week 36 ] [ Designated as safety issue: No ]
    The EORTC QLQ-STO22, the Gastric module of QLQ-C30, is a self administered tool use to assess HROOL of patients with gastric cancer. It consists of 22 items consisting of nine symptom scales or single items (dysphagia, pain, reflux, eating restrictions, anxiety, dry mouth, taste, body image, hair loss) that were developed for participants with gastric cancer. For the symptom scales or single items, participants assessed using a 4-point scale (1=not at all; 2=a little; 3=quite a bit; 4=very much). All scales and single-item scores ranged from 0 to 100. For the symptom scales or single items, a higher score indicated a high level of symptoms and problems, i.e. 0=no symptoms, 100=most severe symptoms.

  • Mean Change in Scores on the Questionnaire EuroQoL-5 Dimensions (EQ-5D) From Baseline to Week 36 [ Time Frame: From Baseline (Day1) to Week 36 ] [ Designated as safety issue: No ]
    The EQ-5D is a generic preference-based HROOL self administered tool comprising of a 5-dimensional health status measure (5D utility measure) and a visual analog rating scale feeling thermometer (T.). 5D utility measures mobility, self-care, usual activities, pain/discomfort, and anxiety/depression. T. assesses participant's current health state. Each 5D utility question was responded to on a 3-point scale, indicating the level of impairment (1=no problem; 2=some or moderate problem(s); 3=unable, or extreme problems). The index utility values corresponding to the 243 health states were defined by the EuroQol classification and calculated based on country-specific regression coefficients. In the UK-based value set, the possible EQ-5D index utility values range from -0.594 to 1. The T. value ranges from 0 to 100. EQ-5D utility index score 0=death, 1=perfect health, -0.594 = worse than death. The T. score: 100=best imaginable health state, 0=worse imaginable health state.
