WARNING

TOXIC DEATHS, HEPATOTOXICITY, NEUTROPENIA, HYPERSENSITIVITY REACTIONS, and FLUID RETENTION
The incidence of treatment-related mortality associated with docetaxel 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 docetaxel as a single agent at a dose of 100 mg/m2 [see Warnings and Precautions (5.1)].
DOCEFREZ 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. 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, AST or ALT, and alkaline phosphatase values should be obtained prior to each cycle of DOCEFREZ therapy [see Warnings and Precautions (5.2)].

DOCEFREZ therapy should not be given to patients with neutrophil counts of <1,500 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 DOCEFREZ[see Warnings and Precautions (5.3)].

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. Hypersensitivity reactions require immediate discontinuation of the DOCEFREZ infusion and administration of appropriate therapy [see Warnings and Precautions (5.4)]. DOCEFREZ must not be given to patients who have a history of severe hypersensitivity reactions to docetaxel or to other drugs formulated with polysorbate 80 [see Contraindications (4)].
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 Warnings and Precautions (5.5)].

1 INDICATIONS AND USAGE

1.1 Breast Cancer

DOCEFREZ is indicated for the treatment of patients with locally advanced or metastatic breast cancer after failure of prior chemotherapy.

1.2 Non-Small Cell Lung Cancer

DOCEFREZ as a single agent is indicated for the treatment of patients with locally advanced or metastatic non-small cell lung cancer after failure of prior platinum-based chemotherapy. DOCEFREZ in combination with cisplatin is indicated for the treatment of patients with unresectable, locally advanced or metastatic non-small cell lung cancer who have not previously received chemotherapy for this condition.

1.3 Prostate Cancer

DOCEFREZ in combination with prednisone is indicated for the treatment of patients with androgen independent (hormone refractory) metastatic prostate cancer.

2 DOSAGE AND ADMINISTRATION

For all indications, toxicities may warrant dosage adjustments [see Dosage and Administration (2.7)].
Administer in a facility equipped to manage possible complications (e.g. anaphylaxis).

2.1 Breast Cancer

  • For locally advanced or metastatic breast cancer after failure of prior chemotherapy, the recommended dose of DOCEFREZ is 60 mg/m2 to 100 mg/m2 administered intravenously over 1 hour every 3 weeks.

2.2 Non-Small Cell Lung Cancer

  • For treatment after failure of prior platinum-based chemotherapy, docetaxel was evaluated as monotherapy, and the recommended dose is 75 mg/m2 administered intravenously over 1 hour every 3 weeks. A dose of 100 mg/m2 in patients previously treated with chemotherapy was associated with increased hematologic toxicity, infection, and treatment-related mortality in randomized, controlled trials [see Boxed Warning, Dosage and Administration ( 2.7), Warnings and Precautions ( 5), Clinical Studies ( 14)]. For chemotherapy-naïve patients, docetaxel was evaluated in combination with cisplatin. The recommended dose of DOCEFREZ is 75 mg/m2 administered intravenously over 1 hour immediately followed by cisplatin 75 mg/m2 over 30 to 60 minutes every 3 weeks [see Dosage and Administration (2.7)].

2.3 Prostate Cancer

  • For hormone-refractory metastatic prostate cancer, the recommended dose of DOCEFREZ is 75 mg/m2 every 3 weeks as a 1 hour intravenous infusion. Prednisone 5 mg orally twice daily is administered continuously [see Dosage and Administration (2.7)].

2.6 Premedication Regimen

All patients should be premedicated with oral corticosteroids (see below for prostate cancer) such as dexamethasone 16 mg per day (e.g., 8 mg twice daily) for 3 days starting 1 day prior to DOCEFREZ administration in order to reduce the incidence and severity of fluid retention as well as the severity of hypersensitivity reactions [see Boxed Warning, Warnings and Precautions ( 5.4)]. For hormone-refractory metastatic prostate cancer, given the concurrent use of prednisone, the recommended premedication regimen is oral dexamethasone 8 mg, at 12 hours, 3 hours and 1 hour before the DOCEFREZ infusion [see Warnings and Precautions (5.4)].

2.7 Dosage Adjustments During Treatment

Breast Cancer
Patients who are dosed initially at 100 mg/m2 and who experience either febrile neutropenia, neutrophils <500 cells/mm3 for more than 1 week, or severe or cumulative cutaneous reactions during DOCEFREZ therapy should have the dosage adjusted from 100 mg/m2 to 75 mg/m2. If the patient continues to experience these reactions, the dosage should either be decreased from 75 mg/m2 to 55 mg/m2 or the treatment should be discontinued. Conversely, patients who are dosed initially at 60 mg/m2 and who do not experience febrile neutropenia, neutrophils <500 cells/mm3 for more than 1 week, severe or cumulative cutaneous reactions, or severe peripheral neuropathy during DOCEFREZ therapy may tolerate higher doses. Patients who develop ≥grade 3 peripheral neuropathy should have DOCEFREZ treatment discontinued entirely.
Non-Small Cell Lung Cancer
Monotherapy with DOCEFREZ for NSCLC treatment after failure of prior platinum-based chemotherapy
Patients who are dosed initially at 75 mg/m2 and who experience either febrile neutropenia, neutrophils <500 cells/mm3 for more than one week, severe or cumulative cutaneous reactions, or other grade 3/4 non-hematological toxicities during DOCEFREZ treatment should have treatment withheld until resolution of the toxicity and then resumed at 55 mg/m2. Patients who develop ≥grade 3 peripheral neuropathy should have DOCEFREZ treatment discontinued entirely.
Combination therapy with DOCEFREZ for chemotherapy-naïve NSCLC
For patients who are dosed initially at DOCEFREZ 75 mg/m2 in combination with cisplatin, and whose nadir of platelet count during the previous course of therapy is <25,000 cells/mm3 , in patients who experience febrile neutropenia, and in patients with serious non-hematologic toxicities, the DOCEFREZ dosage in subsequent cycles should be reduced to 65 mg/m2. In patients who require a further dose reduction, a dose of 50 mg/m2 is recommended. For cisplatin dosage adjustments, see manufacturers’ prescribing information.
Prostate Cancer
Combination therapy with DOCEFREZ for hormone-refractory metastatic prostate cancer
DOCEFREZ should be administered when the neutrophil count is ≥1,500 cells/mm3. Patients who experience either febrile neutropenia, neutrophils <500 cells/mm3 for more than one week, severe or cumulative cutaneous reactions or moderate neurosensory signs and/or symptoms during DOCEFREZ therapy should have the dosage of DOCEFREZ reduced from 75 mg/m² to 60 mg/m². If the patient continues to experience these reactions at 60 mg/m², the treatment should be discontinued.
Combination Therapy with Strong CYP3A4 inhibitors:Avoid using concomitant strong CYP3A4 inhibitors (e.g., ketoconazole, itraconazole, clarithromycin, atazanavir, indinavir, nefazodone, nelfinavir, ritonavir, saquinavir, telithromycin and voriconazole). There are no clinical data with a dose adjustment in patients receiving strong CYP3A4 inhibitors. Based on extrapolation from a pharmacokinetic study with ketoconazole in 7 patients, consider a 50% docetaxel dose reduction if patients require coadministration of a strong CYP3A4 inhibitor. [see Drug Interactions (7), Clinical Pharmacology (12.3)].
