Brief Summary
Randomized, double-blind, placebo-controlled, multicenter Phase-II study. Approximately 120 subjects with CR/PR/SD after platinum compounds and fluoropyrimidines based regimens: up to 6 cycles of cisplatin and 5-fluorouracil or capecitabine, up to 12 cycles of FOLFOX, up to 8 cycles of XELOX, will be randomly assigned (1:1 ratio) to one of the following treatment groups: Arm A: Placebo 4 tablets once daily on day 1-21, every 4 weeks, until intolerance or progression disease Arm B: Regorafenib 160 mg, 4 tablets once daily on days 1-21, every 4 weeks, until intolerance or progression disease Primary Variable: PFS1

- Male of female ≥ 18 years of age
- Have an Eastern Cooperative Oncology Group performance status of 0 or 1 within 14 days prior to the initiation of study treatment
- Diagnosis of histologically confirmed adenocarcinoma of the stomach or gastroesophageal junction
- HER2 negative gastric or gastroesophagel junction cancer ( ICH 0, IHC 1+, IHC + FISH -)
- Locally advanced/metastatic gastric or gastroesophageal junction cancer
- CR/PR/SD after first-line platinum compound and Fluoropyrimidines based chemotherapy
- Measurable disease according to RECIST 1.1 criteria
- Have adequate bone marrow function, liver function, and renal function, as measured by the following laboratory assessments conducted within 7 days prior to the initiation of study treatment:

- Have used biologic response modifiers, such as G-CSF, within 3 weeks of study entry
- Have had prior treatment with regorafenib or any other VEGFR-targeting kinase inhibitor.
- Completed their last dose of chemotherapy more than 8 weeks, whichever came later, prior to randomization.
- Have had prior or concurrent cancer distinct in primary site or histology from GC or GJC within 5 years prior to randomization EXCEPT for curatively treated cervical cancer in situ, no-melanoma skin cancer, or superficial bladder tumors classified as noninvasive tumor (Ta), carcinoma in situ (Tis), or tumor invades lamina propria (T1).
- Have had systemic anticancer therapy including cytotoxic therapy, signal transduction inhibitors, immunotherapy, and/or hormonal therapy within 4 weeks prior to initiation of study treatment.
- Have had a major surgical procedure, open biopsy, or significant traumatic injury within 28 days prior to initiation of study treatment.
- Are pregnant.
- Are breastfeeding.
- Are unable to swallow oral tablets (crushing of study treatment tablets is not allowed).
- Have congestive heart failure classified as New York Heart Association Class 2 or higher
- Have had unstable angina (angina symptoms at rest) or new-onset angina 3 months prior to screening.
- Have had a myocardial infarction 6 months prior to initiation of study treatment.
- Have cardiac arrhythmias requiring anti-arrhythmic therapy, with the exception of beta blockers or digoxin.
- Have uncontrolled hypertension (systolic blood pressure \[SBP\] 140 mmHg or diastolic blood pressure \[DBP\] 90 mmHg) despite optimal medical management.
