FDA Approves Sanofi-Aventis (France)'s New Taxotere(R) (docetaxel) Injection Concentrate Formulation

BRIDGEWATER, N.J., Aug. 5 /PRNewswire/ -- Sanofi-aventis U.S. announced today that the U.S. Food and Drug Administration (FDA) has approved a new one-vial formulation of its chemotherapeutic agent Taxotere® (docetaxel) Injection Concentrate. The 1-vial Taxotere is anticipated to become available to cancer treatment clinics and hospitals nationwide in the fall in both 80 mg and 20 mg dosages.

Introduced more than 14 years ago, Taxotere is approved by the FDA for use in treating patients at specific stages of 5 types of cancer: metastatic and adjuvant breast cancer, metastatic androgen independent prostate cancer, advanced non-small cell lung cancer, advanced gastric adenocarcinoma and locally advanced squamous cell carcinoma of the head and neck.

“This new formulation underscores the commitment sanofi-aventis has made to Taxotere and to healthcare professionals. We look forward to adding this formulation of Taxotere to the arsenal of oncology products sanofi-aventis offers to the cancer community,” said Paul Hawthorne, Vice President and Head of the Oncology Business Unit at sanofi-aventis U.S.

The most common adverse reactions across all Taxotere® indications are infections, neutropenia, anemia, febrile neutropenia, hypersensitivity, thrombocytopenia, neuropathy, dysgeusia, dyspnea, constipation, anorexia, nail disorders, fluid retention, asthenia, pain, nausea, diarrhea, vomiting, mucositis, alopecia, skin reactions and myalgia.

Previously, Taxotere was available to health care professionals in a two vial formulation – one vial containing docetaxel concentrate and the other with the diluent. The 1-vial Taxotere eliminates the need for the initial dilution step with the diluent. The 1-vial Taxotere, now at 20mg/ml concentration, is ready to be added directly into the infusion solution. The new 1-vial Taxotere is expected to help simplify preparation by eliminating the dilution step.

With 1-vial Taxotere, the pharmaceutical ingredients of Taxotere and the one hour IV infusion administration to the patient remain the same.

Taxotere has been used worldwide to treat more than 1.5 million patients, 100,000 of whom were participants in clinical trials.

Important Safety Information for Taxotere (docetaxel) Injection Concentrate

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/m(2) * Taxotere® should not be given to patients with bilirubin > upper limit of normal (ULN), or to patients with AST and/or ALT > 1.5 X ULN concomitant with alkaline phosphatase > 2.5 X ULN o 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 o 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 o Bilirubin, AST or ALT, and alkaline phosphatase values should be obtained prior to each cycle of Taxotere® therapy * Taxotere® therapy should not be given to patients with neutrophil counts of < 1500 cells/mm(3) o 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 a 3-day dexamethasone premedication o Hypersensitivity reactions require immediate discontinuation of Taxotere® infusion and administration of appropriate therapy * 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 * 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).

* Neutropenia (<2,000 neutrophils/mm(3)) occurs in virtually all patients given 60-100 mg/m(2) of Taxotere® and grade 4 neutropenia (<500 cells/mm(3)) occurs in 85% of patients given 100 mg/m(2) and 75% of patients given 60 mg/m(2)

* Patients should be premedicated with oral corticosteroids prior to each Taxotere® administration to reduce the incidence and severity of fluid retention. Patients with pre-existing effusions should be closely monitored from the first dose for possible exacerbation of the effusions

* 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

* 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

* Severe neurosensory symptoms (e.g. 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

* 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

* 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®

* The most common adverse reactions across all Taxotere® indications are infections, neutropenia, anemia, febrile neutropenia, hypersensitivity, thrombocytopenia, neuropathy, dysgeusia, dyspnea, constipation, anorexia, nail disorders, fluid retention, asthenia, pain, nausea, diarrhea, vomiting, mucositis, alopecia, skin reactions and myalgia

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

* Taxotere® should be administered in a facility equipped to manage possible complications (e.g. anaphylaxis)
