⚠ Boxed Warning (Black Box)

WARNING: TOXIC DEATHS, HEPATOTOXICITY, NEUTROPENIA, HYPERSENSITIVITY REACTIONS, and FLUID RETENTION Treatment-related mortality associated with Docetaxel Injection 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 Injection 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 × ULN concomitant with alkaline phosphatase >2.5 × 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 × 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 Injection 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) ]. WARNING: TOXIC DEATHS, HEPATOTOXICITY, NEUTROPENIA, HYPERSENSITIVITY REACTIONS, and FLUID RETENTION See full prescribing information for complete boxed warning. Treatment-related mortality increases with abnormal liver function, at higher doses, and in patients with NSCLC and prior platinum-based therapy receiving Docetaxel Injection at 100 mg/m 2 ( 5.1 ) Avoid use of Docetaxel Injection if bilirubin > ULN, or if AST and/or ALT >1.5 × ULN concomitant with alkaline phosphatase >2.5 × ULN. LFT elevations increase risk of severe or life-threatening complications. Obtain LFTs before each treatment cycle ( 5.2 ) Do not administer Docetaxel Injection to patients with neutrophil counts <1500 cells/mm 3 . Obtain frequent blood counts to monitor for neutropenia ( 4 , 5.3 ) Severe hypersensitivity, including fatal anaphylaxis, has been reported in patients who received dexamethasone premedication. Severe reactions require immediate discontinuation of Docetaxel Injection and administration of appropriate therapy ( 5.5 ) Contraindicated if history of severe hypersensitivity reactions to Docetaxel Injection or to drugs formulated with polysorbate 80 ( 4 ) Severe fluid retention may occur despite dexamethasone ( 5.6 )

Side Effects (Adverse Reactions)

6 ADVERSE REACTIONS The most serious adverse reactions from docetaxel are: Toxic Deaths [see Boxed Warning, Warnings and Precautions (5.1) ] Hepatic Impairment [see Boxed Warning, Warnings and Precautions (5.2) ] Hematologic Effects [see Boxed Warning, Warnings and Precautions (5.3) ] Enterocolitis and Neutropenic Colitis [see Warnings and Precautions (5.4) ] Hypersensitivity Reactions [see Boxed Warning, Warnings and Precautions (5.5) ] Fluid Retention [see Boxed Warning, Warnings and Precautions (5.6) ] Second Primary Malignancies [see Warnings and Precautions (5.7) ] Cutaneous Reactions [see Warnings and Precautions (5.8) ] Neurologic Reactions [see Warnings and Precautions (5.9) ] Eye Disorders [see Warnings and Precautions (5.10) ] Asthenia [see Warnings and Precautions (5.11) ] Alcohol Content [see Warnings and Precautions (5.13) ] The most common adverse reactions across all docetaxel 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. Incidence varies depending on the indication. Adverse reactions are described according to indication. Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice. Responding patients may not experience an improvement in performance status on therapy and may experience worsening. The relationship between changes in performance status, response to therapy, and treatment-related side effects has not been established. Most common adverse reactions across all Docetaxel Injection 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.

These reactions were described using COSTART terms and were considered possibly or probably related to docetaxel. At least 95% of these patients did not receive hematopoietic support. The safety profile is generally similar in patients receiving docetaxel for the treatment of breast cancer and in patients with other tumor types. (See Table 3 .)

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) ]. Cytochrome P450 3A4 inducers, inhibitors, or substrates: May alter docetaxel metabolism. ( 7 )

Contraindications

4 CONTRAINDICATIONS Docetaxel Injection is contraindicated in patients with: neutrophil counts of < 1500 cells/mm 3 [see Warnings and Precautions (5.3) ]. a history of severe hypersensitivity reactions to docetaxel or to other drugs formulated with polysorbate 80. Severe reactions, including anaphylaxis, have occurred [see Warnings and Precautions (5.5) ]. Hypersensitivity to docetaxel or polysorbate 80 ( 4 ) Neutrophil counts of <1500 cells/mm 3 ( 4 )

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 also...

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.
