ClinicalTrials.gov Identifier:
NCT00637247
First received: March 10, 2008
Last updated: November 30, 2010
Last verified: November 2010
  Purpose

The purpose of this study is to determine if imexon in combination with gemcitabine could improve overall survival as compared to gemcitabine alone in subjects with pancreatic cancer that has spread to other organs such as the liver or lungs. The study will also look at the safety of the combination as compared to gemcitabine alone. Participants in the study will be randomly assigned to either treatment and neither the participant or their doctors will know which treatment they will be receiving.

Primary Outcome Measures:
  • Overall Survival for the Intent to Treat Population [ Time Frame: up to 2 years ] [ Designated as safety issue: No ]
    To compare the overall survival duration of the two treatment arms. Overall survival is measured from the time of randomization until reported death. Subjects were censored at last time known alive if lost to follow-up. Alive patients were censored at the last survival follow-up. Follow-up was monthly after off study treatment.

  • To Evaluate and Compare the Tolerability and Toxicity of the Two Treatment Arms [ Time Frame: up to 2 years ] [ Designated as safety issue: Yes ]

Secondary Outcome Measures:
  • Objective Response Rates of the Two Treatment Arms [ Time Frame: one year ] [ Designated as safety issue: No ]
    Objective response is measured by tumor reduction as defined in the RECIST criteria. Tumor shrinkage must be at least 30% to qualify as an objective response.

  • Progression Free Survival [ Time Frame: one year ] [ Designated as safety issue: No ]
    To compare the median progression free survival (PFS) of the two treatment arms. Progression free survival is measured from randomization until the subject has documented disease progression by an objective measure. Subjects were censored if no documented progression had occurred at the one year time point. Subjects must be alive with no more than 20% increase in tumor size to qualify for progression free survival. Changes in tumor size are defined by RECIST criteria.

  • One Year Survival [ Time Frame: one year ] [ Designated as safety issue: Yes ]
    To evaluate the 1-year survival rates of the two treatment arms.

  • To Evaluate the Changes in Blood Levels of CA19.9 on the Two Treatment Arms and Whether There is a Relationship to Objective Response, and PFS [ Time Frame: one year ] [ Designated as safety issue: No ]
  • To Evaluate the OS, ORR, PFS, 1-year Survival, and Changes in CA19.9 of Subjects on the Two Treatment Arms That Completed > 1 Cycle (28 Days) of Protocol Treatment [ Time Frame: one year ] [ Designated as safety issue: No ]

  2. At least one unidimensional measurable metastatic lesion by contrast enhanced CT scan (or MRI in patients ineligible for contrast enhanced CT) that are outside any prior radiation port.
  3. Age at least 18 years.
  4. ECOG performance status 0 or 1.
  5. No prior chemotherapy or radiation therapy.
  6. Projected life expectancy at least 2 months.
  7. If female, neither pregnant nor lactating.
  8. If of child bearing potential must agree to, and be able to use adequate contraception.
  9. Concomitant disease: No respiratory insufficiency requiring oxygen therapy; no angina at rest; no myocardial infarction in previous 3 months; no life threatening ventricular arrhythmias. No uncompensated CHF or NY Heart Association class 3 or 4 cardiac disease.
  10. No other concurrent active malignancy.
  11. No infection requiring parenteral antibiotic therapy at the start of protocol treatment.
  12. Laboratory values within the following criteria:

    Hgb greater than or equal to 9 gm/dL WBC greater than or equal 3,500/mm^3 ANC greater than or equal 1,500/mm^3 Platelet count greater than or equal 100,000/mm^3 Creatinine greater than or equal 2.0 Bilirubin less than or equal to 2.0 Hepatic enzymes (AST, ALT) less than or equal 3 times upper limit of normal (ULN)
