Participants in this single-center, open-label, dose-escalation, Phase 1 study will initially receive intravenous (I.V.) IMC-3G3 once every 2 weeks or on Days 1 and 8 every 3 weeks for 6 weeks (one cycle). After the first cycle, patients experiencing an overall response of complete response (CR), partial response (PR), or stable disease (SD) will continue to receive IMC-3G3 at their cohort dose and schedule until there is evidence of progressive disease (PD), or until other withdrawal criteria are met.

Primary Outcome Measures:
  • Number of participants with Adverse Events (AEs) [ Time Frame: Approximately 16 weeks ] [ Designated as safety issue: Yes ]
  • Number of participants with Serious Adverse Events (SAEs) [ Time Frame: Approximately 16 weeks ] [ Designated as safety issue: Yes ]
  • Number of Patients with a Dose- Limiting Toxicity (DLT) in Cycle 1 [ Time Frame: Approximately 6 weeks ] [ Designated as safety issue: Yes ]

Secondary Outcome Measures:
  • Maximum concentration (Cmax) [ Time Frame: Approximately 16 weeks ] [ Designated as safety issue: No ]
    Cmax for both dosing schedules (Cohort 2, IMC-3G3 administered every 2 weeks) (Cohorts 1 and 3, IMC-3G3 administered every 3 weeks ) will be evaluated during Cycles 1, 2 and 3

  • Area under concentration (AUC) [ Time Frame: Approximately 16 weeks ] [ Designated as safety issue: No ]
    AUC for both dosing schedules (Cohort 2, IMC-3G3 administered every 2 weeks) (Cohorts 1 and 3, IMC-3G3 administered every 3 weeks ) will be evaluated during Cycles 1, 2 and 3

  • Terminal Half-life (t 1/2) [ Time Frame: Approximately 16 weeks ] [ Designated as safety issue: No ]
    t 1/2 for both dosing schedules (Cohort 2, IMC-3G3 administered every 2 weeks) (Cohorts 1 and 3, IMC-3G3 administered every 3 weeks ) will be evaluated during Cycles 1, 2 and 3

  • Clearance (Cl) [ Time Frame: Approximately 16 weeks ] [ Designated as safety issue: No ]
    Cl for both dosing schedules (Cohort 2, IMC-3G3 administered every 2 weeks) (Cohorts 1 and 3, IMC-3G3 administered every 3 weeks ) will be evaluated during Cycles 1, 2 and 3

  • Volume of distribution at steady state (Vss) [ Time Frame: Approximately 16 weeks ] [ Designated as safety issue: No ]
    Vss for both dosing schedules (Cohort 2, IMC-3G3 administered every 2 weeks) (Cohorts 1 and 3, IMC-3G3 administered every 3 weeks ) will be evaluated during Cycles 1, 2 and 3

  • Serum Anti-IMC-3G3 Antibody Assessment (immunogenicity) [ Time Frame: Approximately 16 weeks ] [ Designated as safety issue: No ]

  • Agrees to use adequate contraception for the duration of study participation and for at least 12 weeks after the last dose of study therapy
  • Adequate recovery from recent surgery, chemotherapy, and radiation therapy (including palliative radiation therapy). At least 28 days (6 weeks for nitrosoureas or mitomycin C) must have elapsed from major surgery, prior chemotherapy, prior treatment with an investigational agent or device, or prior radiation therapy.
