Primary Purpose: Treatment
Official Title: A Randomized Phase 2 Study of Human Anti-PDGFRα Monoclonal Antibody IMC-3G3 Plus Mitoxantrone Plus Prednisone or Mitoxantrone Plus Prednisone in Metastatic Castration-Refractory Prostate Cancer Following Disease Progression or Intolerance on Docetaxel-based Chemotherapy

Primary Outcome Measures:
  • Progression-free survival (PFS) [ Time Frame: Approximately 21 months ] [ Designated as safety issue: No ]
    PFS is measured from randomization to the earliest date of the following events: tumor progression according to RECIST v.1.1, unequivocal evidence of progression by bone scan, clinical progression, or death from any cause.

Secondary Outcome Measures:
  • Overall survival (OS) [ Time Frame: Approximately 21 months ] [ Designated as safety issue: Yes ]
    Overall survival time is measured as randomization to date of death from any cause.

  • Objective Response Rate (ORR) [ Time Frame: Approximately 21 months ] [ Designated as safety issue: No ]
    Proportion of participants who achieved a best overall response of complete response (CR) or partial response (PR) compared to the total number of participants. Best response is categorized using the Response Evaluation Criteria In Solid Tumors (RECIST) (ver 1.1) guidelines.

  • Prostate Specific Androgen (PSA) response rate [ Time Frame: Approximately 21 months ] [ Designated as safety issue: No ]
    Proportion of participants with a decrease in PSA from pretreatment to any time point, requiring confirmation no less than 3 weeks after the initial suggestion of response and occuring prior to documentation of PD. Additionally, a PSA response rate equal to the proportion of participants with a decrease in PSA from pretreatment to week 12 or earlier for those who discontinue therapy.

  • Summary Listing of Participants Reporting Treatment-Emergent Adverse Events [ Time Frame: Approximately 21 months ] [ Designated as safety issue: Yes ]
    Summary listing of Participants Reporting Treatment-Emergent Adverse Events that received IMC-3G3.

  • Circulating Tumor Cells and PDGFRα expression [ Time Frame: Approximately 21 months ] [ Designated as safety issue: No ]
  • Maximum concentration (Cmax) cycles 1, 2, 3, and 4 [ Time Frame: Day 1 ] [ Designated as safety issue: No ]
  • Serum Anti-IMC-3G3 Antibody Assessment (immunogenicity) [ Time Frame: Approximately 21 months ] [ Designated as safety issue: Yes ]
    Screen for the development of circulating antibodies against IMC-3G3
