Drug Information available for: Docetaxel

Arm Intervention/treatment
Experimental: docetaxel +ABT-263 Drug: ABT-263
150 mg of ABT-263 is taken orally once daily on Days 1-5 or Days 1-3 of each 21 day cycle. 150 mg of ABT-263 on Days 1-3, 8-10 and 15-17 of each 28-day cycle. This is a dose escalation study, therefore the dose of ABT-263 will change throughout the study.

Drug: Docetaxel
75 mg/m2 will be given by intravenous infusion on day 1 of each 21 -day cycle. 30 mg/m2 will be given by intravenous infusion on day 1, 8, 15 of each 28 -day cycle.
Other Name: docetaxel, taxotere

Primary Outcome Measures :
  1. Assess the safety profile of navitoclax (ABT-263) when administered in combination with a standard and weekly regimen of docetaxel. [ Time Frame: Weekly ]
  2. Study the pharmacokinetic interaction of navitoclax (ABT-263) and docetaxel [ Time Frame: Weekly ]
  3. Determine the maximum tolerated dose (MTD) of navitoclax (ABT-263) with a standard regimen of docetaxel [ Time Frame: Weekly ]
  4. Determine the MTD of both navitoclax and docetaxel with a weekly schedule. [ Time Frame: Weekly ]

Secondary Outcome Measures :
  1. Evaluate safety at the defined recommended Phase 2 dose (RPTD) and schedule in combination with a standard and weekly regimen of docetaxel. [ Time Frame: Bimonthly ]
  2. Evaluate preliminary data regarding progression free survival [ Time Frame: Bimonthly ]
  3. Evaluate preliminary data regarding objective response rate [ Time Frame: Bimonthly ]
  4. Evaluate preliminary data regarding overall survival [ Time Frame: Bimonthly ]
  5. Evaluate preliminary data regarding duration of overall response [ Time Frame: Bimonthly ]
  6. Evaluate preliminary data with Eastern Cooperative Oncology Group (ECOG) performance status [ Time Frame: Bimonthly ]
  7. Evaluate biomarkers [ Time Frame: Bimonthly ]
    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 docetaxel.

  • Subjects with brain metastases must have clinically controlled neurologic symptoms, defined as surgical excision and/or radiation therapy followed by 21 days of stable neurologic function and no evidence of CNS disease progression as determined by CT or MRI within 28 days prior to the first dose of study drug.
  • Subject has an Eastern Cooperative Oncology Group (ECOG) performance score of less then or equal to 1.
  • Subject must have adequate bone marrow, renal and hepatic function per local laboratory reference range as follows:

    • Bone marrow: Absolute Neutrophil Count (ANC) greater then or equal to 1500/microliters; platelets greater then or equal to 150,000/mm^3; hemoglobin greater then or equal to 9.0 g/dL;
    • Renal function: Serum creatinine less then or equal 2.0 mg/dL or calculated creatinine clearance greater than or equal to 50 mL/min;
    • Hepatic function and enzymes: AST and ALT less then or equal to 1.5 x the upper limit of normal (ULN) of institution's normal range, ALP less then or equal to 2.5 x ULN, and bilirubin less then or equal to 1.0 x ULN. Subjects with bone metastasis may have ALP less then or equal to 5.0 x ULN.
    • Coagulation: aPTT and PT not to exceed less than or equal to 1.2 x ULN.
  • Female subjects must be surgically sterile, postmenopausal (for at least one year), or have negative results for a pregnancy test performed as follows:
  • At Screening via a serum sample obtained within 14 days prior to initial study drug administration, and
  • Prior to dosing via a urine sample obtained on Cycle 1 Day 1, if it has been greater then 7 days since obtaining the serum pregnancy test results.

  • The subject has a history of hypersensitivity to docetaxel or other polysorbate 80 drugs.
  • The subject has tested positive for human immunodeficiency virus, HIV (due to potential drug-drug interactions between anti-retroviral medications and navitoclax (ABT-263), as well as anticipated navitoclax (ABT-263) mechanism based lymphopenia that may potentially increase the risk of opportunistic infections and potential drug-drug interactions with certain anti infective agents).
  • The subject has a significant history of cardiovascular (e.g., MI, thrombotic or thromboembolic event in the last 6 months), renal, neurologic, psychiatric, endocrinologic, metabolic, immunologic, or hepatic disease that in the opinion of the investigator would adversely affect his/her participating in this study.
