Brief summary: The PROCEADE PanTumor study aims to investigate M9140 in multiple tumor types which express carcinoembryonic antigen-related cell adhesion molecule 5 (CEACAM5) and it is therefore designed as a matrix study. This study aims to assess the antitumor activity, tolerability, safety, and pharmacokinetics (PK) of M9140 as monotherapy or in combination treatments in adult participants with locally advanced/metastatic CEACAM5 expressing tumors. There will be 3 substudies under this Master Protocol that may be conducted in parallel.

* PROCEADE PanTumor: A Phase 1b/2, Multicenter, Open-Label Study of Anti-CEACAM5 Antibody-Drug Conjugate M9140 in Participants with Advanced Gastric Cancer (Substudy GC);
* PROCEADE PanTumor: A Phase 1b/2, Multicenter, Open-Label Study of Anti-CEACAM5 Antibody-Drug Conjugate M9140 in Participants with Advanced Non-Small Cell Lung Cancer (Substudy NSCLC);
* PROCEADE PanTumor: A Phase 1b/2, Multicenter, Open Label Study of Anti-CEACAM5 Antibody-Drug Conjugate M9140 in Participants With Advanced Pancreatic Cancer (Substudy PDAC).

Detailed description: The study follows a master protocol concept with several separate substudies in specific indications.

* Substudy GC: The study duration per participant is on an average approximately 10 months. This includes a 28-day Screening period, infusion (approximately 1 hour) on Day 1 of every cycle, and Safety Follow-up Visit 30 (± 3) days after the last dose of M9140.
* Substudy NSCLC: Study duration per participant is approximately 12 months. This includes a 28-day Screening period, infusion (approximately 1 hour) on Day 1 of every cycle, and Safety Follow-up Visit 30 (± 3) days after the last dose of M9140.
* Substudy PDAC: Study duration per participant is on an average approximately 8 months. This includes a 28-day Screening period, infusion (approximately 1 hour) on Day 1 of every cycle, and Safety Follow-up Visit 30 (±3) days after the last dose of M9140.

Eligibility criteria: Inclusion Criteria:

* 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 in Part B with CEACAM5low GC/GEJC (defined as IHC \>= 2+ staining in less than (\<) 50% of tumor cells)
* Other protocol defined inclusion criteria could apply

Substudy NSCLC:

* Participants in Part A and Part B with histologically or cytologically documented advanced (Stage III not eligible for resection or curative radiation) or metastatic NSCLC with or without driver genomic alterations
* Participants must have been intolerant/refractory to or progressed after systemic therapies for the advanced/metastatic stage
* 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 3
* 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
