Taxotere Plus Weekly Navelbine and G-CSF: A Phase II Study in Stage IV Breast Cancer

Preclinical data suggest that there may be synergy between vinorelbine and paclitaxel when
the two drugs are used in combination such that the effect of the two together may be better
than either alone. Clinical data suggest that the use of concurrent G-CSF with paclitaxel
and vinorelbine permits the delivery of both agents at approximately 70% of the "full" dose
for either, used alone without G-CSF support, with myelosuppression as the usual
dose-limiting toxicity and no unusual or unexpected complications. Encouragingly, 8/20 (40%)
patients had objective responses, with three complete remissions (15%) in this program of
third-line therapy. Therefore, we now propose to combine docetaxel at about 70% of "full"
dose with vinorelbine at 27.5 mg/m2, the "phase II" dose defined in the previous trial.
Docetaxel will be given on day 1 followed by vinorelbine on days 8 and 15, with G-CSF to be
administered on all days except that of docetaxel administration. The cycle is to be
repeated every three weeks.

Inclusion Criteria:

- Patients must have stage IV, microscopically-confirmed carcinoma of the breast with
histologic slides and/or blocks available for review.

- Patients must have relapse or progression while receiving, or within 12 months of
having received, anthracycline-containing (doxorubicin or mitoxantrone) regimen as
either adjuvant treatment or therapy for advanced breast cancer. Prior Taxol by 3-
or 24-hour infusion is permitted. Patients who have received a maximum dose of
anthracycline (greater than 450 mg/m2) are also eligible.

- Patients must have measurable (bidimensionally) or evaluable disease.

- Patients must be 18 or more years of age.

- Patients must have a Karnofsky Performance Status greater than or equal to 70% at
screen and on the first day of treatment.

- Patients must have a life expectancy of more than 16 weeks.

- Prior irradiation is permitted, provided that prior irradiation does not exceed 25%
of the estimated bone marrow volume and provided that measurable/evaluable disease
exists outside the radiation field OR there must be histologic proof of progressive
disease within a radiation field.

- Informed consent must be obtained prior to registration.

- Patients must be more than 2 weeks from prior surgery; more than 3 weeks from
radiation therapy to the pelvis, spine or long bones; more than 3 weeks from prior
chemotherapy (more than 6 weeks for mitomycin C or nitrosureas), or more than 2 weeks
from prior hormonal therapy.

- All patients must have appropriate central venous access.

Exclusion Criteria:

Patients are excludes if their:

- Granulocyte count is less than 1,500/mm3.

- Platelet count is less than 100,000/mm3.

- Hemoglobin is less than 9 gm/dl.

- Creatinine is greater than 2.0 mg/dl.

- Total bilirubin is greater than ULN (institutional upper limit of normal)..

- SGOT (AST) and/or SGPT (ALT) is greater than 1.5 x ULN concomitant with alkaline
phosphatase greater than 2.5 x ULN.

Patients are excluded if they are:

- In visceral crisis characterized by rapidly progressive hepatic or lymphangitic lung

- Medically unstable.

- Pregnant or lactating.

Patients are excluded if they have:

- Uncontrolled CNS disease.

- Pre-existing clinically significant peripheral neuropathy except for abnormalities
due to cancer.

- Psychological, familial, sociological or geographical conditions which do not permit
weekly medical follow-up and compliance with the study protocol.

- Prior therapy with Navelbine.

- Sensitivity to E. Coli-derived proteins.
