In the three-arm monotherapy trial, TAX 313, which compared Taxotere®
60 mg/m2, 75 mg/m2 and 100 mg/m2 in advanced breast
cancer, the overall safety profile was consistent with the safety profile observed
in previous Taxotere® trials.1

*The number of evaluable patients for neutropenia in the 60 mg/m2,
75 mg/m2, and 100 mg/m2 dose was 148, 190, and 182, respectively.
Discontinuation due to adverse events was reported in 5.3% of patients treated with
Taxotere® 60 mg/m2 vs. 6.9% and 16.5% for patients treated
with Taxotere® 75 mg/m2 and 100 mg/m2, respectively.1
Deaths within 30 days of last treatment occurred in 4.0% of patients treated with
60 mg/m2 compared to 5.3% and 1.6% for patients treated at 75 mg/m2
and 100 mg/m2, respectively.1
The following adverse events were associated with increasing Taxotere®
doses of 60 mg/m2, 75 mg/m2 and 100 mg/m2:
- Fluid retention (26%, 38% and 46%, respectively)
- Thrombocytopenia (7%, 11% and 12%, respectively)
- Neutropenia (92%, 94% and 97%, respectively)
- Febrile neutropenia (5%, 7% and 14%, respectively)
- Treatment-related grade 3/4 infection (2%, 3% and 7%, respectively)
- Anemia (87%, 94% and 97%, respectively)
Hematologic
Febrile neutropenia (<500 cells/mm3 with fever > 38°C with
I.V. antibiotics and/or hospitalization) occurred in 12.3% of patients with metastatic
breast cancer, and in 9.8% of 92 breast cancer patients premedicated with 3-day
corticosteroids.1
Severe infectious episodes occurred in 6.4% of patients with metastatic breast cancer,
and in 5.4% of 92 breast cancer patients premedicated with 3-day corticosteroids.1
Thrombocytopenia (<100,000 cells/mm3) associated with fatal gastrointestinal
hemorrhage has been reported.1
For more information on hematologic events, refer to the WARNINGS section of Taxotere®
prescribing information.
Hypersensitivity Reactions
Severe hypersensitivity reactions to Taxotere® are discussed in the
BOXED WARNING, WARNINGS, and PRECAUTIONS sections of the Taxotere®
prescribing information.
Minor events, including the following, have been reported and resolved after discontinuing
the Taxotere® infusion and receiving appropriate therapy.1
- Flushing
- Rash with or without pruritus
- Chest tightness
- Back pain
- Dyspnea
- Drug fever
- Chills
Fluid Retention
Fluid retention is discussed in the BOXED WARNING, WARNINGS: Premedication Regimen, and PRECAUTIONS sections of the Taxotere®
prescribing information.
Cutaneous
Severe skin toxicities are discussed in the PRECAUTIONS section of the Taxotere® prescribing
information.
Reversible cutaneous reactions characterized by a rash, including localized eruptions
mainly on the feet and/or hands, but also on the arms, face, or thorax, usually
associated with pruritus, have been observed. Eruptions generally occurred within
1 week after Taxotere® infusion, recovered before the next infusion,
and were not disabling.1
Neurologic
Please refer to the PRECAUTIONS section of the Taxotere® prescribing
information for information on neurologic events.
Gastrointestinal
Gastrointestinal reactions (nausea and/or vomiting and/or diarrhea) were generally
mild to moderate in metastatic breast cancer patients. The incidence of severe reactions
was 1% or less for the 92 breast cancer patients premedicated with 3-day corticosteroids.1
Severe stomatitis occurred in 7.4% of patients with metastatic breast cancer, and
in 1.1% of the 92 breast cancer patients premedicated with 3-day corticosteroids.1
Cardiovascular
Clinically meaningful events such as heart failure, sinus tachycardia, atrial flutter,
dysrhythmia, unstable angina, pulmonary edema, and hypertension occurred rarely.1
In a randomized trial, 8.1% (7/86) of metastatic breast cancer patients receiving
Taxotere® 100 mg/m2 who had serial left ventricular ejection
fractions assessed developed deterioration of left ventricular ejection fraction
by > 10% associated with a drop below the institutional lower limit of normal.1
Infusion Site Reactions
Infusion site reactions were generally mild and consisted of hyperpigmentation,
inflammation, redness or dryness of the skin, phlebitis, extravasation, or swelling
of the vein.1

Taxotere® 75 mg/m2
The following table summarizes adverse events from the BCIRG (Breast Cancer International
Research Group) 001 clinical trial comparing Taxotere® 75 mg/m2
+ doxorubicin 50 mg/m2 + cyclophosphamide 500 mg/m2 (TAC)
to 5-fluorouracil 500 mg/m2 + doxorubicin 50 mg/m2 + cyclophosphamide

* COSTART term and grading system for events related to treatment.
Of the 744 patients treated with TAC, 36.3% experienced severe treatment-emergent
adverse events compared to 26.6% of the 736 patients treated with FAC. Dose reductions
due to hematologic toxicity occurred in 1% of cycles in the TAC arm versus 0.1%
of cycles in the FAC arm.1
Six percent of patients treated with TAC discontinued treatment due to adverse events,
compared to 1.1% treated with FAC; fever in the absence of infection and allergy
were the most common reasons for withdrawal among TAC-treated patients.1
Two patients died in each arm within 30 days of their last study treatment; 1 death
per arm was attributed to study drugs.1
Fever and Infection
Fever in the absence of infection was seen in 46.5% of TAC-treated patients and
in 17.1% of FAC-treated patients. Grade 3/4 fever in the absence of infection was
seen in 1.3% and 0% of TAC-treated and FAC-treated patients, respectively.1
Infection was seen in 39.4% of TAC-treated patients compared to 36.3% of FAC-treated
patients. Grade 3/4 infection was seen in 3.9% and 2.2% of TAC-treated and FAC-treated
patients, respectively. There were no septic deaths in either treatment arm.1
Gastrointestinal Events
In addition to gastrointestinal events reflected in the above table, seven patients
in the TAC arm were reported to have colitis/enteritis/large intestine perforation
vs. one patient in the FAC arm. Five of seven TAC-treated patients required treatment
discontinuation; no deaths due to these events occurred.1
Cardiovascular Events
More cardiovascular events were reported in the TAC arm than the FAC arm:
- Dysrhythmias, all grades (7.9% vs. 6.0%, respectively)
- Hypotension, all grades (2.6% vs. 1.1%, respectively)
- Congestive heart failure (1.6% vs. 0.5%, respectively)1
One patient in each arm died due to heart failure.1
Acute Myeloid Leukemia
Treatment-related acute myeloid leukemia (AML) is known to occur in patients treated
with anthracyclines and/or cyclophosphamide, including use in adjuvant therapy for
breast cancer.1
AML occurs at a higher frequency when these agents are given in combination with
radiation therapy. AML occurred in the adjuvant breast cancer trial (BCIRG 001).1
The cumulative risk of developing treatment-related AML at 5 years in BCIRG 001
was 0.4% for TAC-treated patients and 0.1% for FAC-treated patients. This risk of
AML is comparable to the risk observed for other breast cancer therapy regimens
containing anthracyclines and/or cyclophosphamide.1
Addressing Adverse Events
The occurrence of side effects or special considerations may require Taxotere®
dosing adjustments in certain individuals. Please visit the dosing adjustment
guidelines section of this site for more information about dose adjustments.
For more information on Taxotere® adverse events and important safety
information, please refer to the Taxotere® full prescribing information.
