Cytologic or FNA samples are not acceptable. Tumor tissue from bone metastases that is subject to decalcification is not acceptable. - If the patient already has PIK3CA/AKT1/PTEN alteration results available from the FMI commercial tissue-based NGS assay known as FoundationONE CDx TM, then reduced tissue requirements may be required (upon approval by the Medical Monitor) - This tumor tissue sample is required to be submitted as described above for all patients, i.e., if local assessment of PIK3CA/AKT1/PTEN alteration status or central ctDNA is used to confirm biomarker eligibility tumor tissue is still required to assess alteration status centrally - Confirmation of biomarker eligibility, i.e., valid results from either central testing or local testing (at a CLIA or equivalently accredited laboratory) of tumor tissue or blood demonstrating PIK3CA/AKT1/PTEN-altered status Are the trial subjects under 18? no Number of subjects for this age range: F.1.2 Adults (18-64 years) yes F.1.2.1 Number of subjects for this age range 360 F.1.3 Elderly (

Exclusion criteria
