Docetaxel

1 INDICATIONS AND USAGE Docetaxel Injection is a microtubule inhibitor indicated for: • Breast Cancer (BC): single agent for locally advanced or metastatic BC after chemotherapy failure; and with doxorubicin and cyclophosphamide as adjuvant treatment of operable node-positive BC ( 1.1 ) • Non-small Cell Lung Cancer (NSCLC): single agent for locally advanced or metastatic NSCLC after platinum therapy failure; and with cisplatin for unresectable, locally advanced or metastatic untreated NSCLC ( 1.2 ) • Castration-Resistant Prostate Cancer (CRPC): with prednisone in metastatic castration-resistant prostate cancer ( 1.3 ) • Gastric Adenocarcinoma (GC): with cisplatin and fluorouracil for untreated, advanced GC, including the gastroesophageal junction ( 1.4 ) • Squamous Cell Carcinoma of the Head and Neck (SCCHN): with cisplatin and fluorouracil for induction treatment of locally advanced SCCHN ( 1.5 ) 1.1 Breast Cancer Docetaxel Injection is indicated for the treatment of patients with locally advanced or metastatic breast cancer after failure of prior chemotherapy. Docetaxel Injection in combination with doxorubicin and cyclophosphamide is indicated for the adjuvant treatment of patients with operable node-positive breast cancer. 1.2 Non-small Cell Lung Cancer Docetaxel Injection 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. Docetaxel Injection 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 Docetaxel Injection in combination with prednisone is indicated for the treatment of patients with metastatic castration-resistant prostate cancer. 1.4 Gastric Adenocarcinoma Docetaxel Injection in combination with cisplatin and fluorouracil is indicated for the treatment of patients with advanced gastric adenocarcinoma, including adenocarcinoma of the gastroesophageal junction, who have not received prior chemotherapy for advanced disease. 1.5 Head and Neck Cancer Docetaxel Injection in combination with cisplatin and fluorouracil is indicated for the induction treatment of patients with locally advanced squamous cell carcinoma of the head and neck (SCCHN).

12.1 Mechanism of Action Docetaxel is an antineoplastic agent that acts by disrupting the microtubular network in cells that is essential for mitotic and interphase cellular functions. Docetaxel binds to free tubulin and promotes the assembly of tubulin into stable microtubules while simultaneously inhibiting their disassembly. This leads to the production of microtubule bundles without normal function and to the stabilization of microtubules, which results in the inhibition of mitosis in cells. Docetaxel's binding to microtubules does not alter the number of protofilaments in the bound microtubules, a feature which differs from most spindle poisons currently in clinical use.

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).

Treatment is repeated every three weeks. Patients must receive premedication with antiemetics and appropriate hydration for cisplatin administration [ see Dosage and Administration (2.7) ]. 2.5 Head and Neck Cancer Patients must receive premedication with antiemetics, and appropriate hydration (prior to and after cisplatin administr

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 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.

5 WARNINGS AND PRECAUTIONS • Second primary malignancies: In patients treated with Docetaxel Injection-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 cutaneous adverse reactions have been reported. Severe skin toxicity may require dose adjustment or permanent treatment discontinuation. ( 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. ( 5.13 ) • Tumor lysis syndrome: Tumor lysis syndrome has been reported. Patients at risk should be well hydrated and closely monitored during treatment. ( 5.14 ) 5.1 Toxic Deaths Breast Cancer Docetaxel administered at 100 mg/m 2 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/m 2 , 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/m 2 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/m 2 dose in the randomized trials. Among patients who experienced treatment-related mortality at the 75 mg/m 2 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 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. Avoid 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 [ see Warnings and Precautions (5.1) ]. For patients with isolated elevations of transaminase >1.5 × ULN, consider Docetaxel Injection dose modifications [ see Dosage and Administration (2.7) ]. Measure bilirubin, AST or ALT, and alkaline phosphatase prior to each cycle of Docetaxel Injection therapy. 5.3 Hematologic Effects Perform frequent peripheral blood cell counts on all patients receiving Docetaxel Injection. Do not retreat patients with subsequent cycles of Docetaxel Injection until neutrophils recover to a level >1500 cells/mm 3 [ see Contraindications (4) ]. Avoid retreating patients until platelets recover to a level >100,000 cells/mm 3 . A 25% reduction in the dose of Docetaxel Injection is recommended during subsequent cycles follo

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 )

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.
