Eligibility Criteria

Age 18+ · All Participants · 4 Total Inclusion Criteria

Mark “Yes” if the following statements are true for you:
You have recurrent or metastatic solid tumors with HER2 expression, and your disease has progressed despite available treatments which are known to confer benefit; OR you cannot tolerate these treatment options; OR the treatments are contraindicated based on an investigator's judgement
Your ECOG performance status is 0 or 1.
Your disease must be measurable according to the Response Evaluation Criteria in Solid Tumors (RECIST) version 1.1 guidelines.
You must provide a fresh tumor biopsy tissue sample obtained after the participant's most recent HER2-targeting therapy or an archival tumor tissue sample approved by the study Medical Monitor, unless medically infeasible.
