Study Description
Brief Summary:
Patients with locally advanced or metastatic breast cancer and with measurable primary breast tumor will be treated with 70mg docetaxel combined with ketoconazole. Serial tumor biopsies and plasma samples will be taken for gene expression and proteomics studies to identify biomarkers that may predict for treatment response.

Condition or disease Intervention/treatment Phase
Metastatic Breast Cancer Drug: docetaxel and ketoconazole Phase 2

Detailed Description:
We hypothesize that 70mg docetaxel co-administered with ketoconazole would result in similar clinical efficacy as conventional doses of docetaxel (75mg/m2 body surface area) in terms of clinical and pathological response rates in metastatic breast cancer. We further hypothesize that tumor genomic and proteomic changes and serum proteomic changes would correlate with tumor response. We are also looking to correlate drug pharmacokinetics with treatment toxicity, genotype of drug metabolizing enzymes and transporters, and peripheral mononuclear cell gene expression profiles. The primary objectives are to evaluate the clinical response rate of 70mg docetaxel with ketoconazole in metastatic breast cancer, and to evaluate the pathological response rate in the primary tumor following four cycles of docetaxel and ketoconazole.

Arms and Interventions

Arm Intervention/treatment
Experimental: docetaxel and ketoconazole Drug: docetaxel and ketoconazole

Docetaxel will be obtained locally from the manufacturer. Storage conditions for unopened vials, reconstitution, and storage conditions for the reconstituted solution will follow the manufacturer's recommendations. Docetaxel solutions should be prepared and stored in glass, polypropylene or polyolefin containers. Non-PVC containing and polyethylene-lined administration sets should be used.

Ketoconazole is available commercially in 200 mg tablet. Ketoconazole is to be administered at a dose of 200mg BID orally for six doses, starting two days before docetaxel administration. The fifth dose should be administered on the day of and before administering docetaxel, while the sixth dose should be administered in the evening of the day of docetaxel administration.



Outcome Measures

Primary Outcome Measures :
  1. 1. Evaluate the clinical response rate of 70mg docetaxel with ketoconazole in metastatic breast cancer. [ Time Frame: 4 months ]
  2. 2. Evaluate the pathological response rate in the primary tumor following four cycles of docetaxel and ketoconazole. [ Time Frame: 5 months ]

Secondary Outcome Measures :
  1. 1. To study tumor genomics and proteomics and serum proteomics in breast cancer in response to docetaxel/ketoconazole. [ Time Frame: 2 years ]
  2. 2. To compare tumor genomics and proteomics and serum proteomics in breast cancer in response to docetaxel/ketoconazole to that induced by docetaxel alone in a prior study (HO B17/02). [ Time Frame: 2 years ]
  3. 3. To correlate docetaxel pharmacokinetics with (1)Genetic polymorphisms of drug metabolizing enzymes(2)Drug toxicity & tumor response(3)Peripheral mononuclear cell gene expression profiles [ Time Frame: 3 years ]
  4. (4) To study ondansetron pharmacokinetics and correlate that with genetic polymorphisms [ Time Frame: 3 years ]

Criteria

Inclusion Criteria:

  • Karnofsky performance status of 70 or higher.
  • Estimated life expectancy of at least 12 weeks.
  • Adequate organ function including the following:

    - Bone marrow: Absolute neutrophil (segmented and bands) count (ANC) >= 1.5 x 109/L Platelets >= 100 x 109/L

    - Hepatic: Bilirubin <= 1.5 x upper limit of normal (ULN), ALT or AST <= 2.5x ULN, (or <5 X with liver metastases)

Females with childbearing potential must have a negative serum pregnancy test within 7 days prior to study enrollment.

Exclusion Criteria:

  • Prior treatment for locally advanced or metastatic breast cancer.
  • Treatment within the last 30 days with any investigational drug.

  • Poorly controlled diabetes mellitus.
  • Second primary malignancy that is clinically detectable at the time of consideration for study enrollment.
  • Symptomatic brain metastasis.
  • History of significant neurological or mental disorder, including seizures or dementia.
