NCT00148070

Brief Summary

This is a research study which aims to improve the way that doctors determine the dose of chemotherapy given to patients. Right now, chemotherapy is determined by a patient's height and weight. However, some patients metabolize chemotherapy faster or slower than the average person because of a different level of drug metabolizing enzyme in the liver. Therefore, some patients are either given too small or too large a dose of chemotherapy because the amount of enzyme is not taken into account. This research study will examine the use of a simple test, call the Erythromycin Breath Test(ERMBT) to determine the amount of enzyme which can metabolize the chemotherapy drug docetaxel (Taxotere). The dose of docetaxel will be tailored to the amount of enzyme which is available to metabolize the drug for each patient.

Conditions

Metastatic Breast Cancer

Outcome Measures

Primary Outcomes (1)

  • To assess whether assignment of docetaxel dose based on the ERMBT will result in decreased variability in drug area under the curve when compared to dosing based on body surface area.

    12 months

Secondary Outcomes (1)

  • To evaluate the safety and efficacy of tailored-dose docetaxel in metastatic breast cancer.

    12 months

Interventions

DocetaxelDRUG

You will then receive your first dose of docetaxel chemotherapy. It is put through your IV over 1-2 hours. you will receive docetaxel every 3 weeks in the Cancer Center Infusion area.

Erythromycin Breath Test (ERMBT)PROCEDURE

you will have an erythromycin breath test, which is an experimental test which is used to estimate the amount of enzyme produced by your liver which can metabolize the chemotherapy, docetaxel. For this test, you go to the GCRC where you will receive an injection of erythromycin (an antibiotic) which is labeled with a very small amount of radioactive substance. 20 minutes later you will blow air from your mouth into a blue solution until it clears. Your doctors will calculate the dose of docetaxel to be given to you based on this blood test, on your body's albumin level (a protein determined on the blood test), and on your height and weight.

Eligibility Criteria

Age18 Years+
Sexfemale
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Patients with biopsy proven, measurable metastatic breast cancer. Patients with bone-only, and/or effusion-only disease are excluded.
  • Karnofsky performance status equal to 70 or greater.
  • ANC \> 1500, Hgb \> 10, plt \> 100.
  • Patients with some degree of hepatic dysfunction and renal dysfunction are encouraged, in order to evaluate the ability of the ERMBT in tailoring dose in these patient populations.

You may not qualify if:

  • Age less than 18 years.
  • Allergy to erythromycin.
  • Previous treatment with docetaxel. Prior paclitaxel is allowed.
  • Grade \> 2 peripheral neuropathy.
  • No confounding factors present to provide misinterpretation of data (i.e., concurrent malignancy).
  • Patients who are pregnant or nursing will not be eligible for this protocol. Women of childbearing age who are not practicing reliable birth control must have a documented negative serum HCG.
  • Patients who require concurrent treatment with drugs which are known to induce or inhibit CYP3A activity will be ineligible for the trial. This list includes the drugs midazolam, anti-mycotic agents (ketoconazole and related compounds), macrolide antibiotics (erythromycin and related compounds), nifedipine, anti-seizure drugs, and rifampin (induction).
