⚠ Boxed Warning (Black Box)
WARNING: TOXIC DEATHS, HEPATOTOXICITY, NEUTROPENIA, HYPERSENSITIVITY REACTIONS, and FLUID RETENTION Treatment-related mortality associated with docetaxel 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/m 2 [ see Warnings and Precautions (5.1) ] . Avoid the use of Docetaxel Injection in 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 severe 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. Measure bilirubin, AST or ALT, and alkaline phosphatase prior to each cycle of Docetaxel Injection [ see Warnings and Precautions (5.2) ] . Do not administer Docetaxel Injection to patients with neutrophil counts of <1500 cells/mm 3 . Monitor blood counts frequently as neutropenia may be severe and result in infection [ see Warnings and Precautions (5.3) ] . Do not administer Docetaxel Injection to patients who have a history of severe hypersensitivity reactions to docetaxel or to other drugs formulated with polysorbate 80 [ see Contraindications (4) ] . Severe hypersensitivity reactions have been reported in patients despite dexamethasone premedication. Hypersensitivity reactions require immediate discontinuation of the Docetaxel Injection infusion and administration of appropriate therapy [ see Warnings and Precautions (5.5) ] . Severe fluid retention occurred in 6.5% (6/92) of patients despite use of dexamethasone premedication. 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 (5.6) ] .

Description
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. Docetaxel (anhydrous) has the following structural formula: Docetaxel, USP (anhydrous) is a white or almost white crystalline powder with an empirical formula of C 43 H 53 NO 14 , and a molecular weight of 807.88. It is highly lipophilic, soluble in methanol and practically insoluble in water. Docetaxel Injection, USP is a sterile, non-pyrogenic, clear, colorless to pale yellow solution at 10 mg/mL concentration. Each mL contains 10 mg docetaxel, USP (anhydrous), 260 mg polysorbate 80 NF, 4 mg anhydrous citric acid USP, 23% v/v alcohol USP (equivalent to 22.08% v/v absolute alcohol), and polyethylene glycol 300 NF. Docetaxel Injection, USP is available in single-dose vials containing 20 mg (2 mL) docetaxel (anhydrous) USP, and multiple-dose vials containing 80 mg (8 mL) or 160 mg (16 mL) docetaxel (anhydrous) USP. Docetaxel Injection requires NO prior dilution with a diluent and is ready to add to the infusion solution. structural formula

1 INDICATIONS AND USAGE Docetaxel Injection is a microtubule inhibitor indicated for:
Dosage and Administration
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). Administer in a facility equipped to manage possible complications (e.g., anaphylaxis). Administer intravenously (IV) over 1 hour every 3 weeks. PVC equipment is not recommended. Use only a 21 gauge needle to withdraw Docetaxel Injection from the vial.
Side Effects (Adverse Reactions)
6 ADVERSE REACTIONS The most serious adverse reactions from docetaxel are:
Drug Interactions
7 DRUG INTERACTIONS Docetaxel is a CYP3A4 substrate. In vitro studies have shown that the metabolism of docetaxel may be modified by the concomitant administration of compounds that induce, inhibit, or are metabolized by cytochrome P450 3A4. In vivo studies showed that the exposure of docetaxel increased 2.2-fold when it was coadministered with ketoconazole, a potent inhibitor of CYP3A4. Protease inhibitors, particularly ritonavir, may increase the exposure of docetaxel. Concomitant use of Docetaxel Injection and drugs that inhibit CYP3A4 may increase exposure to docetaxel and should be avoided. In patients receiving treatment with Docetaxel Injection close monitoring for toxicity and a Docetaxel Injection dose reduction could be considered if systemic administration of a potent CYP3A4 inhibitor cannot be avoided [ see Dosage and Administration (2.7) , Clinical Pharmacology (12.3) ].
Contraindications
4 CONTRAINDICATIONS Docetaxel Injection is contraindicated in patients with:
Pregnancy and Breastfeeding
8.1 Pregnancy Risk Summary Based on findings in animal reproduction studies and its mechanism of action, Docetaxel Injection 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. Docetaxel Injection contains alcohol which can interfere with neurobehavioral development ( see Clinical Considerations ). In animal reproductive studies, administration of docetaxel to pregnant rats and rabbits during the period of organogenesis caused an increased incidence of 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 ( see Data ). Advise pregnant women and females of reproductive potential of the potential risk to a fetus. The estimated background risk of major birth defects and miscarriage for the indicated populations is unknown. All pregnancies have a background risk of birth defect, miscarriage, or other adverse outcomes. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2% to 4% and 15% to 20%, respectively. Clinical Considerations Docetaxel Injection contains alcohol [ see Warnings and Precautions (5.13) ]. Published studies have demonstrated that alcohol is associated with fetal harm including central nervous system abnormalities, behavioral disorders, and impaired intellectual development. Data Animal data Intravenous administration of ≥0.3 and 0.03 mg/kg/day docetaxel to pregnant rats and rabbits, respectively, during the period of organogenesis caused an increased incidence of intrauterine mortality, resorptions, reduced fetal weights, and fetal ossification delays. Maternal toxicity was...
Overdosage
10 OVERDOSAGE There is no known antidote for Docetaxel Injection overdosage. In case of overdosage, the patient should be kept in a specialized unit where vital functions can be closely monitored. Anticipated complications of overdosage include: bone marrow suppression, peripheral neurotoxicity, and mucositis. Patients should receive therapeutic G-CSF as soon as possible after discovery of overdose. Other appropriate symptomatic measures should be taken, as needed. In two reports of overdose, one patient received 150 mg/m 2 and the other received 200 mg/m 2 as 1-hour infusions. Both patients experienced severe neutropenia, mild asthenia, cutaneous reactions, and mild paresthesia, and recovered without incident. In mice, lethality was observed following single intravenous doses that were ≥154 mg/kg (about 4.5 times the human dose of 100 mg/m 2 on a mg/m 2 basis); neurotoxicity associated with paralysis, non-extension of hind limbs, and myelin degeneration was observed in mice at 48 mg/kg (about 1.5 times the human dose of 100 mg/m 2 basis). In male and female rats, lethality was observed at a dose of 20 mg/kg (comparable to the human dose of 100 mg/m 2 on a mg/m 2 basis) and was associated with abnormal mitosis and necrosis of multiple organs.
