Primary
| Measure | Time frame |
|---|---|
| Main Objective: To evaluate the efficacy of ipatasertib + palbociclib + fulvestrant compared with placebo + palbociclib + fulvestrant in the intent to treat (ITT) population and in patients with PIK3CA/AKT1/PTEN altered tumors (Phase III);Secondary Objective: 1. To evaluate additional efficacy of ipatasertib + palbociclib + fulvestrant compared with placebo + palbociclib + fulvestrant in the ITT population and in patients with PIK3CA/AKT1/PTEN altered tumors (Phase III) 2. To characterize the safety of combining ipatasertib with palbociclib + fulvestrant (Phase Ib and III) 3. To characterize the Pharmacokinetic profiles of ipatasertib and its metabolite (G-037720) in combination with palbociclib and fulvestrant (Phase Ib and III);Primary end point(s): 1. Progression-free survival (PFS) in ITT patients 2. PFS in patients with PIK3CA/AKT1/PTEN altered Tumors;Timepoint(s) of evaluation of this end point: Phase III 1-2. Up to 64 months | — |
Secondary
