inclusion criteria:

• Signed and dated written informed consent in accordance with International Councilfor Harmonisation-Good Clinical Practice (ICH-GCP) and local legislation prior toadmission to the trial.

• Patients ≥18 years old or over the legal age of consent in countries where that isgreater than 18 years at the time of signature of the Informed consent form (ICF).

• Documented (previously established by local testing) Human epidermal growth factorreceptor 2 (HER2) status of:

• Availability and willingness to provide a sample of archival formalin-fixed paraffinembedded (FFPE) tumour tissue material

• Patient with histologically or cytologically confirmed locally advanced unresectableor metastatic solid tumour who has had at least one prior line of therapy formetastatic disease. In the opinion of the Investigator, patients must be unlikely totolerate or derive clinically meaningful benefit from further standard of caretherapy known to prolong survival.
