You may qualify if…

• Provision of fully informed consent prior to any study specific procedures.
• Patients must be ≥ 19 years of age
• Body weight >30 kg
• MET amplification by local NGS (The NGS result of the implementation agency is defined as copy number 4 or higher, which is the standard for amplification)
• Patients with gastric cancer (GC) who are in progressive stages and have progressed during or after 1st or 2nd chemotherapy treatment, regardless of whether they are IO contactless (naïve) or IO

• ECOG performance status 0-1 with no deterioration between screening and the first dose of study treatment
• Patients must have a life expectancy ≥ 3 months from proposed first dose date.
• Patients must have had a washout period of 2 weeks for any prior therapy prior to the start ot study drug. The following intervals between the end of the prior treatment and first dose of study drug must be observed: ≥ 4 weeks for radiotherapy (patients who receive palliative radiation for nontarget lesions need not have a 4 week washout period and can be enrolled if at least >=7 days); patients may receive a stable dose of bisphosphonates or denusomab as long as these were started at least 4 weeks prior to treatment; ≥ 4 weeks for major surgery; ≥ 7 days for minor surgical procedures; ≥ 14 days (or 5 half lives whoever is longest) for any investigational product.
• Patients must have acceptable bone marrow, liver and renal function measured within 28 days prior to administration of study treatment as defined below:
• Haemoglobin ≥9.0 g/dL (within 2 weeks of registration transfusion permitted)
• Absolute neutrophil count (ANC) ≥ 1.5 x 109/L
• Platelet count ≥100 x 109/L (within 2 weeks of registration transfusion permitted)
• Alanine aminotransferase (ALT) and aspartate aminotransferase (AST) ≤2.5 x the upper limit of normal (ULN) with TBL≤ 1x ULN OR TBL >1ULN-≤1.5x ULN with ALT and AST ≤ 1x ULN
• Serum creatinine ≤1.5 x institutional ULN
• Glomerular filtration rate < 45 mL/min as assessed by standard methodology at the investigating centre
• Female patients must be using highly effective contraception during clinical trials and for three months after permanent discontinuation of drug administration, and there should be evidence that they are not breastfeeding, that they are negative in pregnancy tests, or that they meet one of the following criteria in screening:
• Male test subjects with a likely female spouse should be asked to use blocked contraception during the clinical trial and for six months after permanent cessation of administration of the test drug. The test subjects should avoid sperm donation from the start of the test treatment to the 6th month after permanent discontinuation.
• optionally biopsy during the screening window prior to dosing and at progression (fresh frozen will be optionally if clinically feasible)

You may not qualify if…

• Major surgical procedure (as defined by the Investigator) within 28 days prior to the first dose of IP. Note: Local surgery of isolated lesions for palliative intent is acceptable.
• Any previous treatment with MET inhibitors (prior exposure to anti-PD1/PDL1 allowed)<<if the study allows prior anti PD-1, PD-L1 and CTLA-4>> Patients who have received prior anti-PD-1, anti PD-L1 or anti CTLA-4:
• Any gastrointestinal condition that would preclude adequate absorption of savolitinib including but not limited to inability to swallow oral medication, refractory nausea and vomiting, chronic gastrointestinal diseases or previous significant bowel resection, intestinal obstruction or CTCAE grade 3 or grade 4 upper GI bleeding within 4 weeks before the enrollment.
• Active or prior documented autoimmune or inflammatory disorders (including IBD[e.g. Chohn's disease, ulcerative colitis or diverticulitis], SLE, sarcoidosis syndrome, tuberculosis, Wegener syndrome, myasthenia gravis, Graves' disease, rheumatoid arthritis, hypophysitis, uveitis, history of primary immunodeficiency.
• Known to have tested positive for human immunodeficiency virus (HIV) (positive HIV 1/2 antibodies) or active tuberculosis infection (clinical evaluation that may include clinical history, physical examination and radiographic findings, or tuberculosis testing in line with local practice).
• Active hepatitis B (positive HBV surface antigen (HBsAg) result) or hepatitis C (HCV).
• Patients with a past or resolved HBV infection are eligible if:
• Negative for HBsAg and positive for hepatitis B core antibody [anti-HBcAb]. or:
• Positive for HBsAg, but for > 6 months have had normal transaminases and HBV DNA levels <2000 IU/ml (ie, are in an inactive carrier state).
• Subjects with HBV infection, characterised by positive HBsAg and/or anti-HBcAb with undetectable HBV DNA (< 10 IU/ml or under the limit of detection per local lab standard) do not require antiviral therapy prior to randomisation.
• Patients with HBV infection, characterised by positive HBsAg and/or anti-HBcAb with detectable HBV DNA (≥ 10 IU/ml or above the limit of detection per local laboratory standard), must be treated with antiviral therapy for 2-4 weeks prior to the start of study treatment, with the choice of antivirals as per institutional practice. Following antiviral therapy initiation, subjects must show adequate viral suppression (ie, HBV DNA ≤ 2000 IU/mL) prior to randomisation. Participants will remain on antiviral therapy for the study duration and for at least 6 months after the last dose of IP Patients with positive HCV antibody are eligible only if the polymerase chain reaction is negative for HCV RNA.
• Untreated central nervous system (CNS) metastatic disease, leptomeningeal disease, or cord compression. Note: Subjects previously treated for CNS metastases that are asymptomatic, radiographically and neurologically stable for at least 4 weeks and do not require corticosteroids (of any dose) for symptomatic management for at least 4 weeks prior to the first dose of treatment are not excluded.
• Patients with second primary cancer, except: adequately treated non-melanoma skin cancer, curatively treated in-situ cancer of the cervix, or other solid tumours curatively treated with no evidence of disease for ≤3 years.

• Uncontrolled intercurrent illness, including but not limited to, ongoing or active infection, symptomatic congestive heart failure, uncontrolled hypertension, unstable angina pectoris, cardiac arrhythmia, interstitial lung disease, serious chronic gastrointestinal conditions associated with diarrhea, or psychiatric illness/social situations that would limit compliance with study requirement, substantially increase risk of incurring AEs or compromise the ability of the patient to give written informed consent
