The expected duration of the study intervention for participants may vary, based on progression date ; median expected duration of study per participant is estimated 11 months (up to 1 month for screening, a median of 6 months for treatment, and a median of 4 months for end-of-treatment assessments and safety follow-up visit)

Inclusion criteria :

• Metastatic disease progression fulfilling both of the following 2 criteria:

  1. Having progressive disease during or after platinum-based chemotherapy (at least 2 cycles). Maintenance therapy following platinum-based chemotherapy is not considered as a separate regimen. Adjuvant/neoadjuvant treatment for a patient who had a relapse with metastatic disease during or within 6 months of completing treatment will be considered as first-line treatment.

     AND

  2. Having progressive disease during or after 1 immune checkpoint inhibitor (anti-PD1/PD-L1); this could be given as monotherapy or in combination with platinum-based chemotherapy (whatever the order).

• Participants with carcinoembryonic antigen-related cell adhesion molecule (CEACAM) 5 expression of ≥2+ in archival tumor sample (or if not available, fresh biopsy sample) involving at least 50 % of the tumor cell population as demonstrated prospectively by central laboratory via immune histochemistry (IHC).

• At least one measurable lesion by RECIST v1.1.

• Eastern Cooperative Oncology Group (ECOG) performance status 0-1.

• A female participant who agrees to use effective contraceptive methods during and for at least 7 months after the last dose of study intervention.

• A male participant who agrees to use effective contraception methods during and for at least 4 months after the last dose of study intervention

• Signed informed consent

Exclusion criteria:

Participants are excluded from the study if any of the following criteria apply:

• Patients with untreated brain metastases and history of leptomeningeal disease.
• Significant concomitant illnesses that would impair the patient's participation in the study or interpretation of the results.

• Previous history of and/or unresolved corneal disorders. The use of contact lenses is not permitted.
• Radiographic evidence of major airway or blood vessel invasion or intratumor cavitation
• History of uncontrolled hereditary or acquired arterial thrombotic disorder or history of aneurism.
• Major surgery within 28 days prior to Day 1/first IMP infusion,. Postoperative bleeding complications or wound complications from a surgical procedure performed in the last 2 months.
• History of gross hemoptysis within 2 months before the first administration of study intervention.
• Clinically relevant congestive heart failure (CHF; NYHA II-IV, or LVEF less than 50%) or symptomatic or poorly controlled cardiac arrhythmia.
• Any arterial thrombotic event within 6 months before the first administration of study intervention.
• Uncontrolled arterial hypertension (systolic ≥150 mmHg or diastolic ≥90 mmHg) despite standard medical management.
