In case of multiple laboratory data within this period, the most recent data should be used. If a participant has received a recent blood transfusion, the laboratory tests must be obtained ≥ 2 weeks after any blood transfusion.

Disease Specific Criteria: Gastric/GEJ Cancer
1. Participant has histologically confirmed gastric or GEJ adenocarcinoma.
2. Participant with gastric or GEJ adenocarcinoma who has progressed, is intolerant, has refused, or for whom there is no standard approved therapies that impart significant clinical benefit based on investigator’s clinical judgment (no limit to the number of prior treatment regimens).

Disease Specific Criteria: Pancreatic Cancer
1. Participant has histologically or cytologically confirmed pancreatic adenocarcinoma.
2. Participant with pancreatic adenocarcinoma who has progressed, is intolerant, has refused, or for whom there is no standard approved therapies that impart significant clinical benefit based on investigator’s judgement (no limit to the number of prior treatment regimens).
Waivers to the inclusion criteria will NOT be allowed.

Criteri di esclusione: 

Participant will be excluded from participation in the study if any of the following apply:
1. Participant has received other investigational agents, or antineoplastic therapy including immunotherapy or devices concurrently or within 21 days or 5 times the half-life, whichever is shorter, prior to first dose of study intervention administration.
2. Participant has any condition, which, in the investigator’s opinion, makes the participant unsuitable for study participation.
3. Participant has known immediate or delayed hypersensitivity or contraindication to any component of study treatment.
4. Participant has had prior severe allergic reaction or intolerance to known ingredients of ASP2138 or other antibodies, including humanized or chimeric antibodies.
5. Participant weighs < 40 kg.
6. Participant has received systemic immunosuppressive therapy, including systemic corticosteroids 14 days prior to first dose of study intervention. Participant using a physiologic replacement dose of hydrocortisone or its equivalent (defined as up to 30 mg per day of hydrocortisone or up to 10 mg per day of prednisone), receiving a single daily dose of systemic corticosteroids or receiving systemic corticosteroids as pre-medication for radiologic imaging contrast use are allowed.
7. Participant has a complete gastric outlet syndrome or a partial gastric outlet syndrome with persistent/recurrent vomiting.
8. Per investigator judgment, participant has significant gastric bleeding and/or untreated gastric ulcers that exclude the participant from participation.
9. Participant has symptomatic CNS metastases or participant has evidence of unstable CNS metastases even if asymptomatic (e.g., progression on scans). Participants with previously treated CNS metastases are eligible, if they are clinically stable and have no evidence of CNS progression by imaging for at least 4 weeks prior to start of study treatment and are not requiring immunosuppressive doses of systemic steroids (> 30 mg per day of hydrocortisone or > 10 mg per day of prednisone or equivalent) for longer than 2 weeks.
10. Participant is known to have HIV infection. However, participants with CD4+ T cell counts ≥ 350 cells/µL and no history of AIDS-defining opportunistic infections within the past 6 months are eligible. NOTE: Screening for HIV infection should be conducted per local requirements.
11. Participant is known to have active hepatitis B (positive HBsAg) or hepatitis C infection. Testing is required for known history of these infections or as mandated by local requirements. NOTE: Screening for these infections should be conducted per local requirements.
    • For participant who is negative for HBsAg, but HBc Ab positive, an HBV DNA test will be performed and if positive the participant will be excluded.
    • Participant with positive HCV serology, but negative HCV RNA test results are eligible.
    • Participant treated for HCV with undetectable viral load results are eligible
12. Participant has had within 6 months prior to first dose of study intervention any of the following: unstable angina, myocardial infarction, ventricular arrhythmia requiring intervention or hospitalization for heart failure.

15. Participant has a clinically significant disease or co-morbidity that in the opinion of the investigator may adversely affect the safe delivery of treatment within this study or make the participant unsuitable for study participation.
16. Participant has psychiatric illness or social situations that would preclude study compliance per investigator’s judgment.
17. Participant has had a major surgical procedure 28 days before start of study intervention and has not fully recovered, per investigator’s clinical judgment.
18. Participant has received radiotherapy for locally advanced unresectable or metastatic gastric or GEJ or metastatic pancreatic adenocarcinoma 14 days prior to start of study intervention and has NOT recovered from any related toxicity.
19. Participant has another malignancy for which treatment is required, per investigator’s clinical judgment.
20. Participant who has received an CLDN18.2-targeted investigational agent (e.g., zolbetuximab or chimeric antigen receptor CLDN18.2-specific T cells) prior to first dose of study intervention administration is not eligible for dose escalation cohorts. However, a participant who has received an CLDN18.2-targeted investigational agent greater than 28 days or 5 half-lives (whichever is longer) prior to first dose study intervention administration is eligible for dose expansion cohorts only, with the exception of participants who have experienced Grade ≥ 3 GI toxicity after receiving an CLDN18.2-targeted investigational agent.
21. Participant has a history or complication of interstitial lung disease.
Waivers to the exclusion criteria will NOT be allowed.
