  Purpose

This multicenter, international, Phase Ib/II trial consists of two stages: a Phase Ib, open-label stage in which the recommended Phase II dose will be determined for GDC-0068 and GDC-0980 in combination with abiraterone and prednisone/prednisolone and a Phase II, 3-arm, double-blind, randomized comparison of GDC-0068 with abiraterone and prednisone/prednisolone versus placebo with abiraterone and prednisone/prednisolone.

Primary Outcome Measures:
  • Incidence of dose-limiting toxicity (DLTs) for Phase Ib [ Time Frame: up to 28 days ] [ Designated as safety issue: No ]
  • Nature of dose-limiting toxicity (DLTs) for Phase Ib [ Time Frame: up to 28 days ] [ Designated as safety issue: No ]
  • Incidence of adverse events (AEs), graded according to the NCI CTCAE v4.0 [ Time Frame: up to approximately 9 months ] [ Designated as safety issue: No ]
  • Nature of adverse events (AEs), graded according to the NCI CTCAE v4.0 [ Time Frame: up to approximately 9 months ] [ Designated as safety issue: No ]
  • Severity of adverse events (AEs), graded according to the NCI CTCAE v4.0 [ Time Frame: up to approximately 9 months ] [ Designated as safety issue: No ]
  • Radiographic progression-free survival in all patients and in patients with PTEN loss in Phase II [ Time Frame: up to approximately 9 months ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Pharmacokinetics: total exposure (AUC) from Time 0 to the last measurable concentration (AUC0-last) [ Time Frame: Days 1 and 15 of Cycle 1, and on Day 1 of subsequent cycles ] [ Designated as safety issue: No ]
  • Overall survival for Phase II [ Time Frame: up to approximately 24 months ] [ Designated as safety issue: No ]
  • PSA response, defined as a > 50% decrease in PSA from baseline, which is confirmed after >/= 4 weeks by a confirmatory PSA measurement for Phase II [ Time Frame: up to approximately 9 months ] [ Designated as safety issue: No ]
  • Confirmed objective tumor response in patients with measurable soft tissue disease at baseline, as assessed by the investigator per modified RECIST v1.1 for Phase II [ Time Frame: up to approximately 9 months ] [ Designated as safety issue: No ]
  • Duration of objective response in Phase II, defined as the time from first observation of an objective confirmed tumor response until first observation of disease progression, as assessed by the investigator per modified RECIST v1.1 for Phase II [ Time Frame: up to approximately 9 months ] [ Designated as safety issue: No ]
  • Decrease in number of circulating tumor cells for Phase II [ Time Frame: from baseline to up to approximately 9 months ] [ Designated as safety issue: No ]
  • Change in pain symptom score as measured by the modified Brief Pain Inventory-Short Form for Phase II [ Time Frame: from baseline to up to approximately 9 months ] [ Designated as safety issue: No ]
