- Progression-free survival (PFS) using RECIST 1.1 [ Time Frame: 5 years ]
- To compare the two treatment arms with respect to investigator assessed PFS (per RECIST 1.1) in the PIK3CA/AKT1/PTEN altered cohort [ Time Frame: 5 years ]

- Duration of Response (DoR) [ Time Frame: 5 years ]
- Clinical Benefit Rate (CBR); [ Time Frame: 5 years ]
- Overall survival (OS) [ Time Frame: 5 years ]
- Time to commencement of subsequent line of systemic therapy or death (TSST) [ Time Frame: 5 years ]
