Brief Summary:


  1. Current status of treatment options in advanced gastric cancer.

    • The cytotoxic chemotherapy, usually fluoropyrimidine + platinum combination regimen is current standard of care. In case of HER2(+) gastric cancer, the addition of trastuzumab on top of cytotoxic chemotherapy is standard of care.
    • In second-line setting, the cytotoxic chemotherapy in combination with Ramucirumab improved the patients' survival compared with cytotoxic chemotherapy alone.
    • There are few treatment options for gastric cancer patients who have been treated with more than two lines of palliative chemotherapy. Patients with good performance status even after failure to 2 kinds of palliative chemotherapy still need the active anticancer treatment options. Therefore, this is the high unmet medical need.
  2. Current status of immunotherapy development in gastric cancer
  3. The importance of tumor microenvironment
  4. The role of polarized macrophage in TME
  5. The role of polarized macrophage in gastric cancer
  6. Potential of combination of PD1 inhibitor and CSF-1 inhibitor

Based on these rationales, we hypothesized that the combination of PD1 inhibitor and CSF1R inhibitor might be synergistic in gastric cancer. However, the exact in vivo immune modulation by each inhibitor has not been revealed so far. Therefore, we will conduct this "biomarker study of PDR001 in combination with MCS110 in gastric cancer" to see the biologic dynamic modulation with MCS110 and combination (MCS110/PDR001) and to see preliminary efficacy signal with this combination.

<Trial objectives> Primary objective: To see biomarker changes (PDL1, TAM, TIL) by MCS110 monotherapy and MCS110/PDR001 combination (To see the biomarker changes by MCS110 monotherapy at first, then, by MCS110/PDR001 combination in gastric cancer) Secondary objective: To see preliminary efficacy (ORR, irRR, PFS, DOR, DCR, OS) and safety.

Primary Outcome Measures :
  1. Identification of potential biomarkers of MCS110 in combination with PDR001 [ Time Frame: 3weeks ]

  3. Progression-free survival [ Time Frame: 6weeks ]
    Time from randomization until disease progression or death

  4. Duration of response [ Time Frame: 6weeks ]
    Time from documentation of tumor response to disease progression

  5. Disease control rate [ Time Frame: 6weeks ]
    The percentage of patients who have achieved complete response, partial response and stable disease

  6. Overall survival [ Time Frame: 3months ]
    Time from randomization until death from any cause

  7. Safety as measured by number and grade of toxicity events [ Time Frame: 3weeks ]
    According to CTCAE v4.03
