Primary Outcome Measures:
  • Assess the safety profile of ABT-263 in combination with gemcitabine. [ Time Frame: Weekly ] [ Designated as safety issue: Yes ]
  • Study the pharmacokinetic interaction between ABT-263 and gemcitabine. [ Time Frame: Weekly ] [ Designated as safety issue: Yes ]
  • Determine the maximum tolerated dose (MTD) of ABT-263 in combination with gemcitabine. [ Time Frame: Weekly ] [ Designated as safety issue: Yes ]

Secondary Outcome Measures:
  • Evaluate safety at the defined recommended Phase 2 dose (RPTD) and schedule in combination with a standard and weekly regimen of gemcitabine. [ Time Frame: Bi-monthly ] [ Designated as safety issue: No ]
  • Evaluate preliminary data regarding progression free survival (PFS) [ Time Frame: Bi-monthly ] [ Designated as safety issue: No ]
  • Evaluate preliminary data regarding objective response rate (ORR) [ Time Frame: Bi-monthly ] [ Designated as safety issue: No ]
  • Evaluate preliminary data regarding time to tumor progression (TTP) [ Time Frame: Bi-monthly ] [ Designated as safety issue: No ]
  • Evaluate preliminary data regarding overall survival (OS) [ Time Frame: Bi-monthly ] [ Designated as safety issue: No ]
  • Evaluate preliminary data regarding duration of overall response [ Time Frame: Bi-monthly ] [ Designated as safety issue: No ]
  • Evaluate preliminary data with Eastern Cooperative Oncology Group (ECOG) performance status [ Time Frame: Bi-monthly ] [ Designated as safety issue: No ]
  • Evaluate biomarkers to [ Time Frame: Bi-monthly ] [ Designated as safety issue: No ]
    Define the relationship between disease states, B-Cell Lymphoma 2 (Bcl-2) family protein expression, and potential response to the proposed therapy navitoclax when added to a standard and weekly regimen of gemcitabine.


Enrollment: 46
Study Start Date: September 2009
Study Completion Date: November 2011
Primary Completion Date: November 2011 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: gemcitabine +ABT-263 Drug: ABT-263

150mg of ABT-263 is taken orally once daily on Days 1-3 and Days 8-10 out of each 21 day cycle.

325 mg of ABT-263 is taken orally once daily on days 1-3, 8-10, 15-17 out of each 28 day cycle.

This is a dose escalation study, therefore the dose of ABT-263 will change throughout the study.

Other Name: navitoclax
Drug: gemcitabine
Gemcitabine 1000 mg/m2 will be given by intravenous infusion on Day 1 and Day 8 of each 21 day cycle. Gemcitabine 1000 mg/m2 will be given by intravenous infusion on days 1, 8 and 15 of each 28 day cycle.
Other Name: gemzar, gemcitabine

  Eligibility

Ages Eligible for Study:   18 Years and older
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No
Criteria

Inclusion Criteria

  • Age greater then or equal to 18 years.
  • For the 21 and 28-day dose escalation cohorts and the 21-day safety expansion cohort subjects must have histologically and/or cytologically documented cancer for which gemcitabine has been determined to be an appropriate therapy, per the Investigator.
  • For the 28-day safety expansion cohort, subjects must have histologically and/or cytologically documented ductal adenocarcinoma or undifferentiated carcinoma of the pancreas for which gemcitabine has been determined to be an appropriate first-line therapy, per the investigator.

Note: If the 28-day dose escalation schedule is deemed intolerable and further dose de-escalation is not explored, the expanded safety cohort will evaluate navitoclax (ABT-263) in combination with gemcitabine in an additional 12 to 15 subjects with histologically ductal adenocarcinoma or undifferentiated carcinoma of the pancreas for which gemcitabine has been determined to be an appropriate first-line therapy with the RPTD and schedule from the 21-day portion of the study.

  • Measurable disease by CT or MRI as defined RECIST.
