  Purpose

A 2-part, Phase 1-2 controlled, open-label, randomized study in patients with platinum-resistant recurrent ovarian cancer. In Part 1, patients will receive SGI-110 and carboplatin. The optimum dose will be identified in Part 1 based on safety and efficacy. In Part 2, patients will be randomized to receive the dose identified in Part 1 plus carboplatin or one of three treatment of choice at the discretion of the investigator. The treatment of choice consists of topotecan, pegylated liposomal doxorubicin, or paclitaxel.

Primary Outcome Measures:
  • Part 1 (Safety Lead-In): Assess the safety and tolerability of SGI-110 and carboplatin by the incidence of dose limiting toxicities and other adverse events to determine the maximum tolerated dose for Part 2 [ Time Frame: 9 months ] [ Designated as safety issue: Yes ]

    Number of patients with adverse events

    Incidence of dose limiting toxicities


  • Part 2 (Randomized, Controlled, Open Label): Assess and compare progression free survival (PFS) between SGI-110 and carboplatin and Treatment of Choice arms [ Time Frame: 12 months ] [ Designated as safety issue: No ]

    Change in CA-125 tumor biomarker every 4 weeks

    Change in tumor measurements by RECIST 1.1 every 8 weeks



Secondary Outcome Measures:
  • Objective response rate (complete and partial responses) [ Time Frame: 12 months ] [ Designated as safety issue: No ]
    Clinical responses based both on measurable disease and detectable disease

  • Progression free survival at 6 months [ Time Frame: 12 months ] [ Designated as safety issue: No ]
    Assessment of progression free survival as measured by weeks

  • Clinical benefit rate (complete response + partial response + stable disease for at least 3 months) [ Time Frame: 12 months ] [ Designated as safety issue: No ]
    Assessment of clinical benefit rate as measured by weeks

  • CA-125 reduction [ Time Frame: 12 months ] [ Designated as safety issue: No ]
    Percentage of patients with CA-125 reduction by ≥ 50%

  • Duration of Response [ Time Frame: 12 months ] [ Designated as safety issue: No ]
    Duration of response measured in weeks

  • Overall survival [ Time Frame: 12 months ] [ Designated as safety issue: No ]
    Overall survival measured in weeks

  • Pharmacokinetics of combination treatment of SGI-110 and carboplatin [ Time Frame: 12 months ] [ Designated as safety issue: No ]
    Cmax, Cmin, AUC and other secondary PK parameters of SGI-110, decitabine and carboplatin in all patients during Cycle 1

Arms Assigned Interventions
Experimental: SGI-110 and Carboplatin
Part 1: Patients will be dosed with SGI-110 and carboplatin
Drug: SGI-110 and carboplatin
Experimental: SGI-110 and carboplatin or Treatment of Choice
Part 2: Patients will be randomized to receive SGI-110 and carboplatin or Treatment of Choice. Treatment of choice is at the discretion of the investigator and can be one of three standard of care treatments (topotecan, paclitaxel or pegylated liposomal doxorubicin).
