Inclusion criteria
Subjects ≥21 years of age
Dose escalation phase: Histologically or cytologically confirmed diagnosis of gastric, lung, colorectal or breast cancer on file Cohort expansion phase: Histologically or cytologically confirmed diagnosis of Globo H-positive NSCLC
Dose escalation: Subjects with recurrent or metastatic incurable disease that failed to respond to at least one line of anticancer standard therapy and for which standard treatment is no longer effective or tolerable.
Cohort expansion phase: Subjects with recurrent or metastatic NSCLC who have achieved stable disease (SD), or partial response (PR) status after at least 1 regimen of anticancer therapy (i.e., chemotherapy, or targeted therapy, or PD-1/PD-L1 antagonists either alone or in combination) , and there are no standard treatments available except permitted Target or PD-1/PD-L1 therapies
Measurable disease (i.e., present with at least one measurable lesion per RECIST, version 1.1.
Dose Escalation Phase: No known central nervous system (CNS) metastases or neurological symptoms possibly related to active CNS metastasis in Dose Escalation Phase.
Cohort Expansion Phase: Subjects with asymptomatic CNS metastases for at least four weeks before study drug treatment
Performance status: ECOG ≤ 1
Organ Function Requirements - Subjects must have adequate organ functions as defined below:
AST/ALT ≤ 3X ULN (upper limit of normal) AST/ALT ≤ 5X ULN [with underlying liver metastasis] Total bilirubin ≤ 2.0 X ULN Serum creatinine ≤ 1.5X ULN ANC ≥ 1500 /µL Platelets > 100,000/µL
Subjects of child-bearing potential must agree to use acceptable contraceptive methods during treatment and until the end of the study. Subject not of childbearing potential (i.e., permanently sterilized, postmenopausal) can be included in study. Postmenopausal is defined as 12 months with no menses without an alternative medical cause.

Subjects with known or clinically manifest, symptomatic CNS metastases in Dose Escalation Phase.
Subjects with HIV infection, active hepatitis B infection or active hepatitis C infection.
Subjects with any autoimmune disorders requiring iv/oral steroids or immunosuppressive or immunomodulatory therapies.
Subjects with any known uncontrolled inter-current illness including ongoing or active infections, symptomatic congestive heart failure (NYHA>2), unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situations that would limit compliance with study requirements.
Dose escalation phase: Subjects with any of the following MEDICATIONS within 4 weeks prior to IP treatment, except permitted therapies as listed in section 7.1:
Cohort Expansion Phase: Subjects with any of the following MEDICATIONS within 4 weeks prior to IP treatment, except permitted therapies:
Subjects with pleural effusions and/or ascites, due to malignancy, requiring paracentesis every 2 weeks or more frequently.
