入选标准
- •1. Subject has histologically or cytologically confirmed diagnosis of gastric or gastro-esophageal junction (GEJ) adenocarcinoma.
- •2. Subject has gastric or GEJ adenocarcinoma based on radiographic imaging or endoscopic examination.
- •3. Locally advanced or Metastatic gastric or GEJ adenocarcinoma with no standard of care treatment option or subject is ineligible to receive available standard of care treatment option (any line of treatment).
- •4. Subject agrees not to participate in another interventional study while on treatment.
- •5. Subject has Eastern Cooperative Oncology Group (ECOG) performance status 0-1.
- •6. Subject has predicted life expectancy >= 12 weeks.
- •7. Subject must have an available tumor specimen collected at any time prior to the first dose of study treatment.
- •8. Subject must meet all of the pre-specified criteria on the laboratory tests that will be analyzed locally within 7 days prior to the first dose of study drug.
- •Safety part only
- •9. Subject's tumor sample has Claudin (CLDN)18.2 membranous staining with any intensity as determined by central Immunohistochemistry (IHC) testing.
- •Expansion Part Only
- •10. Subject has CLDN18.2 high expression in >=75% of tumor cells demonstrating moderate to strong membranous staining as determined by central IHC testing.
- •11. Subject is an appropriate candidate for a tumor biopsy and is amenable to undergo a tumor biopsy during the Screening period and on-treatment tumor biopsy.
- •12. Subject has at least 1 measurable lesion according to Response Evaluation Criteria In Solid Tumors (RECIST) 1.1 within 28 days prior to the first dose of study treatment. For subjects with only 1 measurable lesion and prior radiotherapy, the lesion must be outside the field of prior radiotherapy or must have documented progression following radiation therapy.
排除标准
- •1. Subject has prior severe allergic reaction or intolerance to a monoclonal antibody, including humanized or chimeric antibodies like IMAB362.
- •2. Subject has had radiotherapy within 2 weeks prior to first dose of study drug. Subject who received palliative radiotherapy to peripheral bone metastases within 2 weeks prior to first dose of study drug and has recovered from all acute toxicities is allowed.
- •3. Subject has received other investigational agents or devices concurrently or within 4 weeks prior first dose of study drug.
- •4. Subject has received systemic immunosuppressive therapy, including systemic corticosteroids 2 weeks prior to first dose of study drug. Subjects using a physiologic replacement dose of hydrocortisone or its equivalent are allowed.
- •5. Subject has gastric outlet syndrome or persistent recurrent vomiting.
- •6. Subject has uncontrolled or significant gastrointestinal hemorrhage.
- •7. Subject has known active central nervous system (CNS) metastases and/or carcinomatous meningitis.
- •8. Subject has a known history of a positive test for human immunodeficiency virus (HIV) infection.
- •9. Subject has a positive test for hepatitis B surface antigen (HBsAg) or hepatitis C virus antibody (anti-HCV). Subjects who are negative for HBsAg, but hepatitis B core antibody (HBcAb) positive, hepatitis B virus deoxyribonucleic acid (DNA) test will be performed and if positive will be excluded. Subjects with positive serology but negative HCV ribonucleic acid (RNA) test results are eligible.
- •10. Subject has had within 6 months prior to first dose of study treatment any of the following: unstable angina, myocardial infarction, ventricular arrhythmia requiring intervention or hospitalization for heart failure
- •11. Subject has active infection requiring systemic therapy.
- •12. Subject has clinically significant other disease or co-morbidity, which may adversely affect the safe delivery of treatment within this trial.
- •13. Subject has psychiatric illness or social situations that would preclude study compliance.
- •14. Subject has active autoimmune disease that has required systemic immunosuppressive treatment in the past 2 years.
- •15. Subject has had a major surgical procedure within 28 days prior to the first dose of study drug.
- •16. Subject has Fridericia-corrected QT interval (QTcF) > 450 msec for males and > 470 msec for females on 12-lead electrocardiogram (ECG) at screening based on local testing.
- •17. Subject has any condition which makes the subject unsuitable for study participation.
- •18. Subject has another active malignancy which is likely to require treatment.
- •19. Subjects who find it difficult to adhere to the provisions of treatment and observation specified in the protocol.
