Brief Summary

Although the overall incidence of gastric cancer has steadily declined in many Western countries during the last few decades, it is still one of the most common tumors in China. It is now well recognised that combination chemotherapy regimens improve patient outcomes, but there is no accepted global standard regimen for advanced gastric cancer. The ToGA study was the first randomized, prospective, multicenter, phase III trial to show the efficacy and safety of Trastuzumab in HER2- positive GC. Trastuzumab reduced the risk of death by 26% (HR 0.74; 95% CI 0∙60, 0∙91; p=0∙0046) when combined with a reference chemotherapy (Capecitabine plus Cisplatin) and prolonged the median survival by nearly 3 months (from 11.1 to 13.8 months) in patients with HER2-positive(FISH+ or IHC3+) advanced GC. Oxaliplatin has been shown to be as effective as cisplatin, and exhibits a favorable toxicity profile with a substantially lower rate of nephrotoxicity, ototoxicity, and myelosuppression. In the current study, the efficacy and safety of Trastuzumab in combination with Oxaliplatin/capecitabine chemotherapy will be evaluated in Chinese patients with HER2 positive advanced or recurrent gastric cancer.

Eligibility Criteria

• Age: 18 Years+
• Sex: all
• Healthy Volunteers: No
• Age Groups: Adult (18-64), Older Adult (65+)

You may qualify if:

• Histologically confirmed adenocarcinoma of the stomach or gastro-oesophageal junction with inoperable locally advanced or recurrent and/or metastatic disease, not amenable to curative therapy.
• Measurable disease, according to the Response Evaluation Criteria in Solid Tumors (RECIST 1.0), assessed using imaging techniques (CT or MRI).
• HER2 positive tumour (primary tumour or metastasis) as assessed by the central laboratory. (Both IHC and Dual SISH will be performed on all patients in the central laboratory.)
• ECOG Performance status 0, 1 or 2.
• Life expectancy of at least 3 months.
• Male or female. Age ≥ 18 years.
• Signed informed consent.

You may not qualify if:

• Previous chemotherapy for advanced/metastatic disease (prior adjuvant/neoadjuvant therapy is allowed if at least 6 months has elapsed between completion of adjuvant/neoadjuvant therapy and enrolment into the study; the total dose of cisplatin should be less than 300mg/m2, adjuvant/neoadjuvant therapy with oxaplatin is not allowed).
• No prior use of EGFR-targeting drugs,such as Trastuzumab,lapatinib or other TKIs.
• Lack of physical integrity of the upper gastrointestinal tract or malabsorption syndrome (e.g. patients with partial or total gastrectomy can enter the study, but not those with a jejunostomy probe).
• Patients with active (significant or uncontrolled) gastrointestinal bleeding.
• Residual relevant toxicity resulting from previous therapy (with the exception of alopecia), e.g. neurological toxicity ≥ grade 2 NCI-CTCAE 4.0.
• Other malignancy within the last 5 years, except for carcinoma in situ of the cervix, or basal cell carcinoma.
• Neutrophil count \< 1.5 × 109/L, or hemoglobin \< 90 g/L,or platelet count \< 100 × 109/L.
• Serum bilirubin \> 1.5 × upper limit of normal (ULN); or, AST or ALT \> 2.5 × ULN(or \> 5 × ULN in patients with liver metastases); or, alkaline phosphatase \> 2.5 × ULN (or \> 5 × ULN in patients with liver metastases, or \> 10 × ULN in patients with bone but no liver metastases); or, albumin \< 25 g/L.
• Creatinine clearance \< 60 mL/min.
• History of documented congestive heart failure; angina pectoris requiring medication;evidence of transmural myocardial infarction on ECG; poorly controlled hypertension (systolic BP \> 180 mmHg or diastolic BP \> 100 mmHg); clinically significant valvular heart disease; or high risk uncontrollable arrhythmias.
• Baseline LVEF \< 50% (measured by echocardiography or MUGA).
• Patients with dyspnoea at rest due to complications of advanced malignancy or other disease, or who require supportive oxygen therapy.
• Patients receiving chronic or high dose corticosteroid therapy. (Inhaled steroids and short courses of oral steroids for anti-emesis or as an appetite stimulant are allowed).
• Clinically significant hearing abnormality.
• Known dihydropyrimidine dehydrogenase (DPD) deficiency.
