Eligibility
Min Age: 18 Years
Inclusion Criteria9
- Has a pathologically documented HER2-positive or HER2-expressing (except for cohort 2h where the requirement is HER2-null), advanced/unresectable, recurrent, or metastatic malignant solid tumor that is refractory to or intolerable with standard treatment, or for which no standard treatment is available.

- Life expectancy of ≥ 3 months.
- \. Has pathologically documented advanced/unresectable, recurrent, or metastatic EC (including UCS and USPC) and has progressed on or after at least 1 line of systemic treatment including platinum-based therapy and exposure to ICI but no more than prior 3 lines of therapy for advanced/unresectable, or metastatic disease. Note: endocrine therapy will not qualify as a systemic therapy line.
