Primary Outcome Measures:
  • Incidence rate of dose limiting toxicities (DLT) [ Time Frame: 28 days (from the time of first dose) ] [ Designated as safety issue: Yes ]
    Phase l; cycle = 28 days

  • Incidence rate of patients with Prostate Specific Antigen (PSA) response [ Time Frame: >= 12 weeks ] [ Designated as safety issue: No ]
    Phase ll only

Secondary Outcome Measures:
  • Number of adverse events (AEs) [ Time Frame: 18 months ] [ Designated as safety issue: Yes ]
    Phase l, Phase ll

  • PK parameters [ Time Frame: 18 months ] [ Designated as safety issue: No ]
    Phase l, Phase ll

  • Prostate Specific Antigen (PSA) response (≥50% in PSA reduction) [ Time Frame: 18 months ] [ Designated as safety issue: No ]
    Phase l only

  • Progression free survival (PFS) [ Time Frame: baseline, until disease progression up to 6 months (6 cycle) ] [ Designated as safety issue: No ]
    Phase ll only; cycle = 28 days

  • Number of serious adverse events (SAEs) [ Time Frame: 18 months ] [ Designated as safety issue: Yes ]
    Phase l, Phase ll

  • Time to PSA progression [ Time Frame: up to 2 months (cycle 2) ] [ Designated as safety issue: No ]
    Phase ll; cycle = 28 days

  • Overall Response rate (ORR) [ Time Frame: up to 2 months (cycle 2) ] [ Designated as safety issue: No ]
    Phase ll

  • Radiological Time to Progression (rTTP) [ Time Frame: baseline, until date of documented disease progression ] [ Designated as safety issue: No ]
    Phase ll only

  • Prostate Specific Antigen (PSA) response (≥30% in the PSA reduction) [ Time Frame: 18 months ] [ Designated as safety issue: No ]
    Phase ll only

  • Best PSA response at any time during the study [ Time Frame: 18 months ] [ Designated as safety issue: No ]
    Phase ll only

Other Outcome Measures:
  • Evaluation of serum hormone levels [ Time Frame: 18 months ] [ Designated as safety issue: No ]
    Phase I, Phase II

  • Correlate plasma exposure parameters of CFG920 and serum hormones [ Time Frame: 18 months ] [ Designated as safety issue: No ]
    Phase I, Phase II

  • Evaluate moleculare profiles [ Time Frame: 18 months ] [ Designated as safety issue: No ]
    Phase I, Phase II
