• Cerebrovascular accident/stroke (< 6 months prior to enrollment)
• Other protocol defined exclusion criteria could apply
  • Substudy GC - Participants with prior therapy with irinotecan
  • Substudy NSCLC:

Más betegség

• Participant has a history of malignancy within 3 years before the date of enrollment (exceptions are squamous and basal cell carcinomas of the skin and carcinoma in situ of the cervix, benign prostate neoplasm/hypertropia, or malignancy that in the opinion of the Investigator, with concurrence with the Sponsor's Medical Monitor, is considered cured with minimal risk of recurrence within 3 years)
• Participants with active chronic inflammatory bowel disease (e.g., ulcerative colitis, Crohn's disease, intestinal perforation) and/or bowel obstruction

Laborértékek

• Other protocol defined inclusion criteria could apply
  • Substudy GC:
• Participants in Part A and Part B with documented histopathological diagnosis of advanced or metastatic, HER2 negative, gastric or GEJ (with an epicenter 2 centimeter (cm) proximal or distal to the GEJ) adenocarcinoma, who were intolerant/refractory to or progressed after systemic therapies for the advanced/metastatic stage that must have included (provided there is no medical contraindication and these agents are locally approved and available) a fluoropyrimidine and a platinum agent and an Immune checkpoint inhibitors (ICI) for participants with a known microsatellite instability-high (MSI-H) status or participants whose tumor express PD-L1 with a CPS greater than or equal (>=) 1
• Participants must have received and progressed (according to RECIST 1.1) on at least 1 line of therapy for the treatment of advanced/metastatic disease but no more than 2
• Participants in Part A with CEACAM5high GC/GEJC (defined as IHC >= 2+ staining in >= 50% of tumor cells)

• Participants who received a platinum-containing regimen or a targeted therapy as (neo)-adjuvant therapy for early-stage disease, if relapse or metastases occurred during or within 3 months after regimen completion, are considered to have received a line of treatment in the advanced setting
• Participants in Part A with CEACAM5 high-expressing EGFR tumors (including participants with any driver genomic alterations other than EGFR mutations
• Participants in Part B with CEACAM5 high known EGFR mutated tumors as assessed according to local clinical practice
• Other protocol defined inclusion criteria could apply
  • Substudy PDAC:
• Participants with histologically or cytologically confirmed advanced or metastatic PDAC, who were intolerant/refractory to or progressed after systemic therapies for the advanced metastatic stage that must have included (provided there is no medical contraindications, and these agents are locally approved and available; FOLFIRINOX regimen or NALIRIFNOX regimen or Nab-paclitaxel/gemcitabine regimen
