Primary Outcome Measures:
  • Overall Survival (OS) [ Time Frame: Baseline to date of death by any cause (up to approximately 12 months) ] [ Designated as safety issue: No ]
    OS is defined as the time from randomization to death from any cause; OS was censored on date of last contact for participants still alive at time of analysis.


Secondary Outcome Measures:
  • Number of Participants With Treatment-emergent Adverse Events (AEs), Serious AEs, and Grade 3 or Higher AEs [ Time Frame: From initiation of study drug to end of study (up to 8 months) ] [ Designated as safety issue: No ]
    Treatment-emergent AEs are defined as and AE that occurred after the first dose of study drug up to 30 days after the last dose of study drug. AEs were graded using National Cancer Institute's Common Terminology Criteria for Adverse Events (CTCAE) version 4.0. Treatment-emergent AEs could have occurred during loading dose period, chemotherapy period, maintenance period, and treatment period A detailed summary of adverse events is located in the Reported Adverse Event Module.

  • Number of Participants With ≥ 1 Hematology Abnormality and ≥ 1 Grade 3 or Higher Hematology Abnormality [ Time Frame: Screening through End of Study Visit (Within 30 [±7] days following withdrawal of study treatment) ] [ Designated as safety issue: No ]
  • Number of Participants With ≥ 1 Chemistry Laboratory Abnormality and ≥ 1 Grade 3 or Higher Chemistry Laboratory Abnormality [ Time Frame: Screening through End of Study Visit (Within 30 [±7] days following withdrawal of study treatment) ] [ Designated as safety issue: No ]
  • Number of Participants With ≥ 1 Urinalysis Abnormality and ≥ 1 Grade 3 or Higher Urinalysis Abnormality [ Time Frame: Screening through End of Study Visit (Within 30 [±7] days following withdrawal of study treatment) ] [ Designated as safety issue: No ]
  • Best Objective Tumor Response [ Time Frame: Baseline to measured progressive disease (up to approximately 12 months) ] [ Designated as safety issue: No ]
    Complete Response (CR): Complete disappearance of all measurable and non-measurable disease with no new lesions. Any pathological lymph node (target or non-target) must have a reduction in short axis to < 10 mm). All markers of disease must have normalized. Partial Response (PR): A decrease from baseline of ≥ 30% of the diameter(s) of all target measurable lesions with no unequivocal progression of non-measurable lesions and no new lesions. Stable Disease (SD): Does not qualify for CR, PR, or progression. Disease Progression (PD): If at least one of following criteria is met: 1. Appearance of any new lesion or site of disease. 2. A 20% increase in the sum of the diameter(s) of target measurable lesions over either the smallest sum observed or over baseline if no decrease during therapy has occurred. The sum must also demonstrate an absolute increase of at least 5 mm. 3. Unequivocal progression of non-target lesions alone.

  • Overall Response Rate (ORR) and Disease Control Rate [ Time Frame: Baseline to measured progressive disease (up to approximately 12 months) ] [ Designated as safety issue: No ]
    Participants were defined as having an "overall response" if their best response is either confirmed CR, confirmed PR, unconfirmed CR or unconfirmed PR. ORR was defined as the percent of participants who had an overall response. Participants were defined as having "disease control" if their best response is confirmed CR, confirmed PR, unconfirmed CR, unconfirmed PR or SD. The disease control rate (DCR) was defined as the percent of participants with disease control. (See "Best Objective Tumor Response" Outcome Measure above for response category definitions.)

  • Duration of Overall Response Rate [ Time Frame: Baseline to measured progressive disease (up to approximately 12 months) ] [ Designated as safety issue: No ]
    Overall response was defined has having a response of Complete Response (CR) or Partial Response (PR). (See "Best Objective Tumor Response" Outcome Measure above for response category definitions.) Duration of Response is defined as the duration from the first overall response to the first Stable Disease (SD) or Disease Progression (PD), whichever happens first. If no SD or PD, subject is censored at the last tumor assessment (prior to other anti-cancer therapy if applicable).

  • Progression-free Survival (PFS) [ Time Frame: Baseline to measured progressive disease (up to approximately 12 months) ] [ Designated as safety issue: No ]
    PFS was defined as the time from randomization to the date of disease progression or death, whichever occurred first, before or after treatment discontinuation. For participants still on study and those who remained alive and had not progressed after treatment discontinuation, PFS was censored on the date of the last tumor assessment.

  • Change From Baseline in Serum Hsp27 levels by End of Treatment [ Time Frame: Baseline, End of Treatment (up to approximately 12 months) ] [ Designated as safety issue: No ]
    End of Treatment is last non-hemolyzed observation up to last dose + 30 days. Includes unscheduled and additional treatment visits. Hemolyzed samples were excluded.

  • Change From Baseline in Serum Clusterin Levels by End of Treatment [ Time Frame: Baseline, End of Treatment (up to approximately 12 months) ] [ Designated as safety issue: No ]
    End of Treatment is last observation up to last dose + 30 days. Includes unscheduled and additional treatment visits.

  • Change From Baseline in Circulating Tumor Cell (CTC) Count by End of Treatment [ Time Frame: Baseline, End of Treatment (up to approximately 12 months) ] [ Designated as safety issue: No ]
    End of Treatment is last observation up to last dose + 30 days. Includes unscheduled and additional treatment visits.

  • Serum OGX-427 Cmax and Trough Levels [ Time Frame: Cycle 1 Day 1 through Cycle 6 Day 1, End of Treatment (up to approximately 12 months) ] [ Designated as safety issue: No ]
    only C1 to C6, Ctrough and Cmax - as well report EOT Ctrough

Detailed Description:
Following 3 loading doses, participants receive chemotherapy and study drug on a 21-day cycle during the Treatment Period (Chemotherapy Period) until disease progression, completion of 6 cycles, toxicity or voluntary participant withdrawal. Participants who do not have documented disease progression and have completed a minimum of four cycles of chemotherapy continue to receive weekly Study Drug maintenance therapy during the Maintenance Period until disease progression or the participant fulfills one of the other reasons for withdrawal from protocol treatment, unless they have been discontinued from protocol treatment for unacceptable toxicity related to study drug. All participants have an End of Treatment (EOT) visit when they are withdrawn from all study treatment (chemotherapy and maintenance). All participants are followed until documented disease progression. Once disease progression is documented, participants enter a Survival Follow-up Period during which data are collected regarding further cancer therapy, secondary malignancy, and survival status.
