3. Consent for a tumor biopsy at screening
4. Progressive disease and no effective therapy exists
5. Measurable disease as per RECIST v1.1 criteria
6. ECOG Performance status of ≤ 2

Exclusion criteria:

2. Clinically significant cardiac, respiratory, gastrointestinal, renal, hepatic or neurological conditions.
3. A history of serious allergic reactions, which in the opinion of the investigator pose an increased risk of serious infusion reactions.
4. Monocular vision or has media opacities or any other condition that precludes monitoring of the retina or the fundus, or has a history of ophthalmology exam with retina or cornea abnormalities
5. Previously treated with anti-pCAD biologic therapies.

6. Received anti-cancer therapies within the following time frames prior to the first dose of study treatment:

   • Conventional cytotoxic chemotherapy: ≤4 weeks
   • Biologic therapy (eg, antibodies), other than ADCs: ≤4 weeks
   • Non-cytotoxic small molecule therapeutics: ≤5 T1/2 or ≤2 weeks (whichever is longer)
   • Other investigational agents: ≤4 weeks
