Objectives

I.  Compare the objective response rate and time to progression of patients 
with metastatic breast cancer, who have not had prior therapy for advanced 
disease following treatment with doxorubicin (DOX) vs. paclitaxel (TAX) vs. 
DOX/TAX with granulocyte colony-stimulating factor (G-CSF).

II.  Compare the toxicity of these 3 regimens.

III.  Determine by means of a crossover design whether DOX and TAX exhibit 
cross-resistance.

IV.  Compare the quality of life of patients who receive DOX vs. TAX vs. 
TAX/DOX/G-CSF.

V.  Compare the quality of life of patients who receive DOX vs. TAX as 
second-line therapy.

VI.  Evaluate the relation of steady-state TAX levels to therapeutic response 
and toxicity.

     Cremophor (e.g., anesthetics and muscle relaxants)
  No active, unresolved infection
     At least 7 days since parenteral antibiotics
  No second malignancy within 5 years except:
     Curatively treated nonmelanomatous skin cancer
     Curatively treated in situ cervical cancer
  No pregnant women
  Adequate contraception required of fertile patients
  Participation in a quality-of-life assessment optional


Expected Enrollment

A maximum of 733 patients will be entered over approximately 22 months; 220 
evaluable patients will be accrued to Arms A and B.  If at least 11 responses 
are seen in the first 40 patients entered on Arm C (phase II portion of the 
study), a total of 220 evaluable patients will be enrolled on that arm as well.

Arm B:  Single-Agent Chemotherapy.  Paclitaxel, TAX, NSC-673089.

Arm C:  2-Drug Combination Chemotherapy with Hematologic Toxicity Attenuation. 
 DOX; TAX; with Granulocyte Colony-Stimulating Factor (Amgen), G-CSF,

Note: The purpose of most clinical trials listed in this database is to test new cancer treatments, or new methods of diagnosing, screening, or preventing cancer. Because all potentially harmful side effects are not known before a trial is conducted, dose and schedule modifications may be required for participants if they develop side effects from the treatment or test. The therapy or test described in this clinical trial is intended for use by clinical oncologists in carefully structured settings, and may not prove to be more effective than standard treatment. A responsible investigator associated with this clinical trial should be consulted before using this protocol.
