  • Progression free survival (PFS) [ Time Frame: Time from registration until objective tumor progression or death for any reason that occurs by the end of the study. ] [ Designated as safety issue: Yes ]
  • Overall survival (OS) [ Time Frame: Time from registration to the date of death. ] [ Designated as safety issue: Yes ]

  • Clinical Benefit Rate (CBR) [ Time Frame: proportion of patients with confirmed CR, PR, and SD over 24 weeks. ] [ Designated as safety issue: Yes ]
  • Duration of Response (DR) [ Time Frame: Time from first assessment of CR or PR until the first date of PD or death within 60 days of the last tumor assessment or registration, whichever is first. ] [ Designated as safety issue: Yes ]
    Median time will be estimated using the Kaplan Meier method. 95% confidence interval of the median time will be estimated.
  • Safety Evaluations [ Time Frame: Focus on AEs and laboratory assessments. ] [ Designated as safety issue: Yes ]

    AEs will be coded according to the Medical Dictionary for Regulatory Activities Terminology (MedDRA) and the severity of the toxicities will be graded according to the NCI CTCAE criteria, version 3.0, where applicable. Concomitant medications will be coded according to WHO Medication Dictionary for Concomitant Medication.

    All AEs will be summarized (incidence) and listed by the System Organ Class (SOC), preferred term, toxicity/severity grade, and causal relationship. In addition, separate summaries of SAEs and Grade 3 or 4 AEs will be presented. Cardiac AEs including asymptomatic LVEF drops will also be summarized in separate tables.

    Hematological and chemistry laboratory parameters will be graded according to the NCI CTCAE criteria, where applicable. Absolute values and changes from baseline will be summarized by cycle. In addition, worst severity grade will also be summarized.

A Study of Trastuzumab in Combination With TS-ONE & Cisplatin in First-line Human Epidermal Growth Factor Receptor 2 (HER2)-Positive Advanced Gastric Cancer
A Phase 2 Study of Trastuzumab in Combination With TS-ONE and Cisplatin in First-line Human Epidermal Growth Factor Receptor 2 (HER2)-Positive Advanced Gastric Cancer.

The investigators hypothesis is that the combination of TS-ONE with cisplatin and trastuzumab is safe and as effective as combination treatment for HER2 positive gastric cancer.

Gastric carcinoma is the second most common cause of cancer death world-wide. Approximately 875,000 patients are diagnosed world-wide with gastric cancer each year. Gastric cancer is often diagnosed at an advanced stage1. At diagnosis, while some patients have gastric carcinoma that extends within loco-regional confines and can undergo a curative resection, many patients cannot undergo curative resection. Gastric cancer continues to pose a major medical challenge.

While advanced gastric carcinoma is incurable, chemotherapy can have a palliative effect in symptomatic patients. Chemotherapy improves outcome compared to best supportive care in gastric cancer. Various chemotherapeutic agents including 5-FU, mitomycin, etoposide, cisplatin, irinotecan and the taxanes, have demonstrated activity as monotherapy. Combination chemotherapy has been shown to have better survival outcomes than single agent chemotherapy Standard chemotherapy for advanced gastric carcinoma includes a fluoropyrimidine and platinum -based combination chemotherapy.

Interventional
Phase 2
Endpoint Classification: Efficacy Study
Intervention Model: Single Group Assignment
Masking: Open Label
Primary Purpose: Treatment
Gastric Cancer
Drug: Trastuzumab in Combination with TS-ONE and cisplatin
Subjects will receive treatment that combined TS-ONE, cisplatin and trastuzumab every 3 weeks in this study. This 3 weeks period of time is called a cycle. The cycle will be repeated until subject experience disease progression or unbearable toxicities or they choose to withdraw from the study. Each cycle is numbered in order.
Experimental: Trastuzumab in Combination with TS-ONE and cisplatin
The initial dose of cisplatin is fixed to be 60 mg/m2 and intravenously administered over 1 hour on day 1 of the cycle. TS-ONE is orally administered consecutive 14-day followed by 7-day rest. The initial standard dose of TS-ONE is determined based on the body surface area tabled below. Trastuzumab is intravenously administered with the loading dose of 8 mg/kg followed by maintenance dose of 6mg/kg in day 1 of each cycle. The study treatments are repeated every 3 weeks. Study treatment can continue until PD, but cisplatin can be skipped or discontinued if patients experienced unbearable toxicity which comes from cisplatin.
Intervention: Drug: Trastuzumab in Combination with TS-ONE and cisplatin

Inclusion Criteria:

  1. Patients with histologically proved adenocarcinoma of advanced gastric cancer.
  2. Patients who have HER2-positive cancer confirmed with IHC and/or FISH.
  3. Patients with proved presence of measurable (RECIST criteria) lesions within 28 days before enrollment.
  4. Patients without prior treatment (ex. radiotherapy, chemotherapy, hormonal therapy): Patients who completed adjuvant chemotherapy more than 180 days before may be enrolled but those who received TS-ONE or cisplatin shall be excluded.
  5. Patients with the following function of bone marrow, liver and kidney based on the laboratory tests measured within 14 days before enrollment. Hemoglobin >= 8.0 g/dL leukocytes >=3,000/mcL absolute neutrophil count >=1,500/mcL platelets >=100,000/mcL total bilirubin within normal institutional limits AST(SGOT)/ALT(SGPT)=<2.5 X institutional upper limit of normal ALP < twice of the upper limit of normal, creatinine within normal institutional limits or creatinine clearance >=60 mL/min for patients with creatinine levels above institutional normal (When AST(GOT), ALT(GPT) and ALP do not satisfy the conditions above and these values are considered to be caused by cancer, the decision is based on the discretion of investigators or co-investigators) Creatinine clearance can be estimated using Cockcroft-Gault formula man: Ccr (mL/min) = body weight (kg) x (140 - age)/(72 x serum creatinine (mg/dL)), woman: Ccr = male Ccr x 0.85].
  6. ECOG performance status =<2 (Karnofsky >60%; see Appendix A).
