Clinical Pharmacology

Taxotere^® (docetaxel) is a semisynthetic derivative of a compound isolated from the needles of the European yew tree (Taxus baccata).¹ It was identified in 1986 as an alternative to paclitaxel and comes from a renewable resource.

The unique chemical structure of Taxotere^® contains two modifications relative to paclitaxel

A hydroxy group replacing an acetyl group at C-10
C-13 side chain variations

Research has demonstrated that these structural changes confer enhanced solubility in aqueous solution.*

WARNING

The incidence of treatment-related mortality associated with Taxotere® therapy is increased in patients with abnormal liver function, in patients receiving higher doses, and in patients with non-small cell lung carcinoma and a history of prior treatment with platinum-based chemotherapy who receive Taxotere® as a single agent at a dose of 100 mg/m² (see WARNINGS section of the prescribing information)
Taxotere® should generally not be given to patients with bilirubin > upper limit of normal (ULN), or to patients with serum glutamic-oxaloacetic transaminase (SGOT) and/or serum glutamic-pyruvic transaminase (SGPT) > 1.5 X ULN concomitant with alkaline phosphatase > 2.5 X ULN
- Patients with elevations of bilirubin or abnormalities of transaminase concurrent with alkaline phosphatase are at increased risk for the development of grade 4 neutropenia, febrile neutropenia, infections, severe thrombocytopenia, severe stomatitis, severe skin toxicity, and toxic death
- Patients with isolated elevations of transaminase > 1.5 X ULN also had a higher rate of febrile neutropenia grade 4 but did not have an increased incidence of toxic death
- Bilirubin, SGOT or SGPT, and alkaline phosphatase values should be obtained prior to each cycle of Taxotere® therapy and reviewed by the treating physician
Taxotere® therapy should not be given to patients with neutrophil counts of < 1500 cells/mm³
- In order to monitor the occurrence of neutropenia, which may be severe and result in infection, frequent blood-cell counts should be performed on all patients receiving Taxotere®
Severe hypersensitivity reactions characterized by generalized rash/erythema, hypotension and/or bronchospasm, or very rarely fatal anaphylaxis, have been reported in patients who received the recommended 3-day dexamethasone premedication
- Patients should be observed closely for hypersensitivity reactions, especially during the first and second infusions
Taxotere® must not be given to patients who have a history of severe hypersensitivity reactions to Taxotere® or to other drugs formulated with polysorbate 80
- All patients should be premedicated with oral corticosteroids such as dexamethasone (see DOSAGE AND ADMINISTRATION section of the prescribing information)
Severe fluid retention occurred in 6.5% (6/92) of patients despite use of a 3-day dexamethasone premedication regimen. It was characterized by one or more of the following events: poorly tolerated peripheral edema, generalized edema, pleural effusion requiring urgent drainage, dyspnea at rest, cardiac tamponade, or pronounced abdominal distention (due to ascites) (see PRECAUTIONS section of the prescribing information)

Additional Warnings

Treatment-related acute myeloid leukemia (AML) or myelodysplasia has occurred in patients given anthracyclines and/or cyclophosphamide, including use with Taxotere® in adjuvant therapy of breast cancer

Taxotere® can cause fetal harm when administered to pregnant women. Women of childbearing potential should be advised to avoid becoming pregnant during therapy with Taxotere®

Precautions

Localized erythema of the extremities with edema followed by desquamation has been observed

— In case of severe skin toxicity, an adjustment in dosage is recommended (see DOSAGE AND ADMINISTRATION section of the prescribing information)

Severe neurosensory symptoms (paresthesia, dysesthesia, pain) were observed in 5.5% (53/965) of metastatic breast cancer patients, and resulted in treatment discontinuation in 6.1%

— When these symptoms occur, dosage must be adjusted; if symptoms persist, treatment should be discontinued (see DOSAGE AND ADMINISTRATION section of the prescribing information)

Severe asthenia was reported in 14.9% (144/965) of metastatic breast cancer patients, but led to treatment discontinuation in only 1.8%

— Symptoms of fatigue and weakness may last a few days up to several weeks and may be associated with deterioration of performance status in patients with progressive disease

In patients treated with TCF for gastric cancer, the incidence of serious adverse events was higher in patients ≥65 years than in younger patients. Adverse events (all grades) occurring at rates ≥10% higher in elderly patients included lethargy, stomatitis, diarrhea, dizziness, edema, and febrile neutropenia/neutropenic infection.

Taxotere® should be administered only under the supervision of a qualified physician experienced in the use of antineoplastic agents. Appropriate management of complications is possible only when adequate diagnostic and treatment facilities are readily available
