An additional archival tissue sample collected greater than 3 months prior to screening must be available and of sufficient quantity, as defined above, at the time of screening. If an archival tissue sample (collected greater than 3 months prior to screening) is not available, a subject may be included provided the pre-treatment tumor biopsy is obtained and after discussion and agreement from Sponsor (Medical Monitor or designee). 3. Consent to provide on-treatment tumor biopsy. When at least 10 treatment tumor biopsies have been collected, the Sponsor will provide written notification of a change to the requirement. * Eastern Cooperative Oncology Group performance status (ECOG PS) of 0 or 1. * Life expectancy ≥3 months. * Has adequate bone marrow reserve and organ function at baseline based on local laboratory data defined as follows within 14 days prior to Cycle 1 Day 1: * Platelet count: ≥100,000/mm\^3 or ≥100 × 10\^9/L (platelet transfusions are not allowed up to 14 days prior to Cycle 1 Day 1 to meet eligibility) * Hemoglobin: ≥9.0 g/dL (transfusion and/or growth factor support is allowed) * Absolute neutrophil count: ≥1500/mm\^3 or ≥1.5 × 10\^9/L * Serum creatinine (SCr) OR creatinine clearance (CrCl): SCr ≤ 1.5 × upper limit of normal (ULN), OR CrCl ≥ 30 mL/min as calculated using the Cockcroft- Gault equation or measured CrCl; confirmation of CrCl is only required when creatinine is \>1.5 × ULN * Alanine aminotransferase /aspartate aminotransferase: ≤3 × ULN (if liver metastases are present, ≤5 × ULN) * Total bilirubin: ≤1.5 × ULN if no liver metastases (\<3 × ULN in the presence of documented Gilbert's syndrome \[unconjugated hyperbilirubinemia\] or liver metastases) * Serum albumin: ≥2.5 g/dL * Prothrombin time (PT) or PT-international normalized ratio (INR) and activated partial thromboplastin time (aPTT) / partial thromboplastin time (PTT): ≤1.5 × ULN except for subjects on coumarin- derivative anticoagulants or other similar anticoagulant therapy, who must have PT-INR within therapeutic range as deemed appropriate by the Investigator Exclusion Criteria: * Any history of interstitial lung disease (including pulmonary fibrosis or radiation pneumonitis), has current interstitial lung disease (ILD), or is suspected to have such disease by imaging during screening. * Clinically severe pulmonary compromise (based on Investigator's assessment) resulting from intercurrent pulmonary illnesses including, but not limited to: 1. any underlying pulmonary disorder (e.g., pulmonary emboli, severe asthma, severe chronic obstructive pulmonary disease, restrictive lung disease, pleural effusion) 2. any autoimmune, connective tissue or inflammatory disorder with pulmonary involvement (eg, rheumatoid arthritis, Sjögren's syndrome, sarcoidosis) * OR prior complete pneumonectomy. * Is receiving chronic systemic corticosteroids dosed at \>10 mg prednisone or equivalent anti-inflammatory activity or any form of immunosuppressive therapy prior to Cycle 1 Day 1.

Any cytotoxic chemotherapy, investigational agent or other anticancer drug(s) from a previous cancer treatment regimen or clinical study \<14 days or 5 half-lives, whichever is longer; 3. Monoclonal antibodies other than immune checkpoint inhibitors, such as bevacizumab (anti-VEGF) and cetuximab (anti-EGFRs) \<28 days; 4. Immune checkpoint inhibitor therapy \<21 days; 5. Major surgery (excluding placement of vascular access) \<4 weeks; 6. Radiotherapy treatment to \>30% of the bone marrow or with a wide field of radiation \<28 days or palliative radiation therapy \<14 days; 7. Chloroquine/hydroxychloroquine ≤14 days. * Prior treatment with an anti-HER3 antibody and/or antibody drug conjugate (ADC) that consists of an exatecan derivative that is any topoisomerase I inhibitor (e.g, trastuzumab deruxtecan). * Has unresolved toxicities from previous anticancer therapy, defined as toxicities (other than alopecia) not yet resolved to National Cancer Institute Common Terminology Criteria for Adverse Events (NCI-CTCAE) v5.0 Grade ≤1 or baseline. * Had primary malignancies other than CRC within 3 years prior to Cycle 1 Day 1, except adequately resected non-melanoma skin cancer, curatively treated in-situ disease, or other solid tumors curatively treated. * Uncontrolled or significant cardiovascular disease prior to Cycle 1 Day 1. * Known Hepatitis B and/or Hepatitis C infection, such as those with serologic evidence of viral infection within 28 days of Cycle 1 Day 1. 1. Participants with past or resolved hepatitis B virus (HBV) infection are eligible if: * Hepatitis B surface antigen (HBsAg) negative and hepatitis B core antibody (anti-HBc) positive; OR * HBsAg positive and HBV deoxyribonucleic acid (DNA) viral load is documented to be ≤2000 IU/mL in the absence of anti-viral therapy and during the previous 12 weeks prior to the viral load evaluation with normal transaminases values (in the absence of liver metastasis); OR * HBsAg positive and HBV DNA viral load is documented to be ≤2000 IU/mL in the absence of anti-viral therapy and during the previous 12 weeks prior to the viral load evaluation for participants with liver metastasis and abnormal transaminases with a result of AST/ALT \<3 × ULN. 2. Participants with a history of hepatitis C infection will be eligible for enrollment only if the viral load according to local standards of detection is documented to be below the level of detection in the absence of anti-viral therapy during the previous 12 weeks (ie, sustained viral response according to the local product label but no less than 12 weeks, whichever is longer). * Participant with any human immunodeficiency virus (HIV) infection. * Any evidence of severe or uncontrolled systemic diseases (including active bleeding diatheses, active infection), psychiatric illness/social situations, geographical factors, substance abuse, or other factors which in the Investigator's opinion makes it undesirable for the participant to participate in the study or which would jeopardize compliance with the protocol.
