About This Medication
11 DESCRIPTION Docetaxel is an antineoplastic agent belonging to the taxoid family. It is prepared by semisynthesis beginning with a precursor extracted from the renewable needle biomass of yew plants. The chemical name for docetaxel is (2R,3S)-N-carboxy-3-phenylisoserine,N-tert-butyl ester, 13-ester with 5β-20-epoxy-1,2α,4,7β,10β,13α-hexahydroxytax-11-en-9-one 4-acetate 2-benzoate trihydrate. Docetaxel has the following structural formula: Docetaxel is a white or almost white crystalline powder with an molecular formula of C 43 H 53 NO 14 •3H 2 O, and a molecular weight of 861.9. It is freely soluble in acetone, soluble in methanol and practically insoluble in water. One-vial Docetaxel Injection, USP Docetaxel injection, USP is a sterile, non-pyrogenic, pale yellow to brownish-yellow solution at 20 mg/mL concentration. Each mL contains docetaxel trihydrate equivalent to 20 mg docetaxel anhydrous, 540 mg polysorbate 80, 0.5 mg citric acid anhydrous and 395 mg ethyl alcohol dehydrated. Docetaxel injection, USP is available in single use vials containing 20 mg (1 mL), 80 mg (4 mL) or 160 mg (8 mL) docetaxel anhydrous. Docetaxel injection, USP requires NO prior dilution with a diluent and is ready to add to the infusion solution. Image

5 WARNINGS AND PRECAUTIONS Second primary malignancies: In patients treated with docetaxel-containing regimens, monitor for delayed AML, MDS, NHL, and renal cancer. ( 5.7 ) Cutaneous reactions: Reactions including erythema of the extremities with edema followed by desquamation may occur. Severe skin toxicity may require dose adjustment ( 5.8 ) Neurologic reactions: Reactions including paresthesia, dysesthesia, and pain may occur. Severe neurosensory symptoms require dose adjustment or discontinuation if persistent ( 5.9 ) Eye disorders: Cystoid macular edema (CME) has been reported and requires treatment discontinuation ( 5.10 ) Asthenia: Severe asthenia may occur and may require treatment discontinuation ( 5.11 ) Embryo-fetal toxicity: Can cause fetal harm. Advise patients of the potential risk to a fetus and to use effective contraception. ( 5.12 , 8.1 , 8.3 ) Alcohol content: The alcohol content in a dose of docetaxel injection may affect the central nervous system. This may include impairment of a patient's ability to drive or use machines immediately after infusion ( 5.12 ) 5.1 Toxic Deaths Breast Cancer Docetaxel administered at 100 mg/m² was associated with deaths considered possibly or probably related to treatment in 2.0% (19/965) of metastatic breast cancer patients, both previously treated and untreated, with normal baseline liver function and in 11.5% (7/61) of patients with various tumor types who had abnormal baseline liver function (AST and/or ALT >1.5 times ULN together with AP >2.5 times ULN). Among patients dosed at 60 mg/m², mortality related to treatment occurred in 0.6% (3/481) of patients with normal liver function, and in 3 of 7 patients with abnormal liver function. Approximately half of these deaths occurred during the first cycle. Sepsis accounted for the majority of the deaths. Non-small Cell Lung Cancer Docetaxel administered at a dose of 100 mg/m² in patients with locally advanced or metastatic non-small cell lung cancer who had a history of prior platinum based chemotherapy was associated with increased treatment-related mortality (14% and 5% in two randomized, controlled studies). There were 2.8% treatment-related deaths among the 176 patients treated at the 75 mg/m² dose in the randomized trials. Among patients who experienced treatment-related mortality at the 75 mg/m² dose level, 3 of 5 patients had an ECOG PS of 2 at study entry [ see Dosage and Administration ( 2.2 ), Clinical Studies ( 14 ) ] . 5.2 Hepatic Impairment Patients with combined abnormalities of transaminases and alkaline phosphatase should not be treated with docetaxel [ see Boxed Warning , Use in Specific Populations ( 8.6 ), Clinical Studies ( 14 ) ]. 5.3 Hematologic Effects Perform frequent peripheral blood cell counts on all patients receiving docetaxel. Patients should not be retreated with subsequent cycles of docetaxel until neutrophils recover to a level >1500 cells/mm and platelets recover to a level > 100,000 cells/mm 3 . A 25% reduction in the dose of docetaxel is recommended during subsequent cycles following severe neutropenia (<500 cells/mm 3 ) lasting 7 days or more, febrile neutropenia, or a grade 4 infection in a docetaxel cycle [see Dosage and Administration ( 2.7 ) ]. Neutropenia (<2000 neutrophils/mm 3 ) occurs in virtually all patients given 60 mg/m² to 100 mg/m² of docetaxel and grade 4 neutropenia (<500 cells/mm 3 ) occurs in 85% of patients given 100 mg/m² and 75% of patients given 60 mg/m². Frequent monitoring of blood counts is, therefore, essential so that dose can 3be adjusted. Docetaxel should not be administered to patients with neutrophils <1500 cells/mm 3 . Febrile neutropenia occurred in about 12% of patients given 100 mg/m² but was very uncommon in patients given 60 mg/m². Hematologic responses, febrile reactions and infections, and rates of septic death for different regimens are dose related [see Adverse Reactions ( 6.1 ), Clinical Studies ( 14 ) ]. Three breast cancer patients with severe liver impairment (bilirubin >1.7 times ULN) developed fatal gastrointestinal bleeding associated with severe drug induced thrombocytopenia. In gastric cancer patients treated with docetaxel in combination with cisplatin and fluorouracil (TCF), febrile neutropenia and/or neutropenic infection occurred in 12% of patients receiving G-CSF compared to 28% who did not. Patients receiving TCF should be closely monitored during the first and subsequent cycles for febrile neutropenia and neutropenic infection [see Dosage and Administration ( 2.7 ), Adverse Reactions ( 6 ) ]. 5.4 Enterocolitis and Neutropenic Colitis Enterocolitis and neutropenic colitis (typhlitis) have occurred in patients treated with docetaxel alone and in combination with other chemotherapeutic agents, despite the co-administration of G-CSF. Caution is recommended for patients with neutropenia, particularly at risk for developing gastrointestinal complications. Enterocolitis and neutropenic enterocolitis may develop at any time, and could lead to death as early as the first day of symptom onset. Monitor patients closely from onset of any symptoms of gastrointestinal toxicity. Inform patients to contact their healthcare provider with new, or worsening symptoms of gastrointestinal toxicity [see Dosage and Administration ( 2 ), Warnings and Precautions ( 5.3 ) , Adverse Reactions ( 6.2 )]. 5.5 Hypersensitivity Reactions Patients should be observed closely for hypersensitivity reactions, especially during the first and second infusions. Severe hypersensitivity reactions characterized by generalized rash/erythema, hypotension and/or bronchospasm, or very rarely fatal anaphylaxis, have been reported in patients premedicated with 3 days of corticosteroids. Severe hypersensitivity reactions require immediate discontinuation of the docetaxel infusion and aggressive therapy. Patients with a history of severe hypersensitivity reactions should not be rechallenged with docetaxel. Patients who have previously experienced a hypersensitivity reaction to paclitaxel may develop a hypersensitivity reaction to docetaxel that may include severe or fatal reactions such as anaphylaxis. Monitor patients with a previous history of hypersensitivity to paclitaxel closely during initiation of docetaxel therapy. Hypersensitivity reactions may occur within a few minutes following initiation of a docetaxel infusion. If minor reactions such as flushing or localized skin reactions occur, interruption of therapy is not required. All patients should be premedicated with an oral corticosteroid prior to the initiation of the infusion of docetaxel [ see Dosage and Administration ( 2.6 ) ]. 5.6 Fluid Retention Severe fluid retention has been reported following docetaxel therapy. Patients should be premedicated with oral corticosteroids prior to each docetaxel administration to reduce the incidence and severity of fluid retention [ see Dosage and Administration ( 2.6 ) ]. Patients with pre-existing effusions should be closely monitored from the first dose for the possible exacerbation of the effusions. When fluid retention occurs, peripheral edema usually starts in the lower extremities and may become generalized with a median weight gain of 2 kg. Among 92 breast cancer patients premedicated with 3-day corticosteroids, moderate fluid retention occurred in 27.2% and severe fluid retention in 6.5%. The median cumulative dose to onset of moderate or severe fluid retention was 819 mg/m². Nine of 92 patients (9.8%) of patients discontinued treatment due to fluid retention: 4 patients discontinued with severe fluid retention; the remaining 5 had mild or moderate fluid retention. The median cumulative dose to treatment discontinuation due to fluid retention was 1021 mg/m². Fluid retention was completely, but sometimes slowly, reversible with a median of 16 weeks from the last infusion of docetaxel to resolution (range: 0 to 42+ weeks). Patients developing peripheral edema may be treated with standard measures, e.g., salt restriction, oral diuretic(s). 5.7 Second Primary Malignancies Second primary malignancies, notably acute myeloid leukemia (AML), myelodysplastic syndrome (MDS), Non-Hodgkin's Lymphoma (NHL), and renal cancer, have been reported in patients treated with docetaxel-containing regimens. These adverse reactions may occur several months or years after docetaxel-containing therapy. Treatment-related acute myeloid leukemia (AML) or myelodysplasia has occurred in patients given anthracyclines and/or cyclophosphamide, including use in adjuvant therapy for breast cancer. In the adjuvant breast cancer trial (TAX316) AML occurred in 3 of 744 patients who received docetaxel, doxorubicin and cyclophosphamide (TAC) and in 1 of 736 patients who received fluorouracil, doxorubicin and cyclophosphamid [ see Clinical Studies ( 14.2 ) ]. In TAC-treated patients, the risk of delayed myelodysplasia or myeloid leukemia requires hematological follow-up. Monitor patients for second primary malignancies [ see Adverse Reactions ( 6.1 ) ]. 5.8 Cutaneous Reaction 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 ( 2.7 ) ]. The discontinuation rate due to skin toxicity was 1.6% (15/965) for metastatic breast cancer patients. Among 92 breast cancer patients premedicated with 3-day corticosteroids, there were no cases of severe skin toxicity reported and no patient discontinued docetaxel due to skin toxicity. 5.9 Neurologic Reactions 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 [ see Dosage and Administration ( 2.7 ) ]. Patients who experienced neurotoxicity in clinical trials and for whom follow-up information on the complete resolution of the event was available had spontaneous reversal of symptoms with a median of 9 weeks from onset (range: 0 to 106 weeks). Severe peripheral motor neuropathy mainly manifested as distal extremity weakness occurred in 4.4% (42/965). 5.10 Eye Disorders Cystoid macular edema (CME) has been reported in patients treated with docetaxel. Patients with impaired vision should undergo a prompt and comprehensive ophthalmologic examination. If CME is diagnosed, docetaxel injection treatment should be discontinued and appropriate treatment initiated. Alternative non-taxane cancer treatment should be considered. 5.11 Asthenia Severe asthenia has been reported in 14.9% (144/965) of metastatic breast cancer patients but has 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. 5.12 Embryo-Fetal Toxicity Based on findings from animal reproduction studies and its mechanism of action, docetaxel can cause fetal harm when administered to a pregnant woman [ see Clinical Pharmacology ( 12.1 ) ]. Available data from case reports in the literature and pharmacovigilance with docetaxel use in pregnant women are not sufficient to inform the drug-associated risk of major birth defects, miscarriage or adverse maternal or fetal outcomes. In animal reproduction studies, administration of docetaxel to pregnant rats and rabbits during the period of organogenesis caused embryo-fetal toxicities, including intrauterine mortality, at doses as low as 0.02 and 0.003 times the recommended human dose based on body surface area, respectively. Advise pregnant women and females of reproductive potential of the potential risk to a fetus. Verify pregnancy status in females of reproductive potential prior to initiating docetaxel. Advise females of reproductive potential to use effective contraception during treatment and for 6 months after the last dose of docetaxel. Advise male patients with female partners of reproductive potential to use effective contraception during treatment and for 3 months after the last dose of docetaxel [ see Use in Specific Populations ( 8.1 , 8.3 ) ]. 5.13 Alcohol Content Cases of intoxication have been reported with some formulations of docetaxel due to the alcohol content. The alcohol content in a dose of docetaxel Injection may affect the central nervous system and should be taken into account for patients in whom alcohol intake should be avoided or minimized. Consideration should be given to the alcohol content in docetaxel Injection on the ability to drive or use machines immediately after the infusion. Each administration of docetaxel injection at 100 mg/m² delivers 2.0 g/m² of ethanol. For a patient with a BSA of 2.0 m², this would deliver 4.0 grams of ethanol [ see Description ( 11 ) ]. Other docetaxel products may have a different amount of alcohol.
