This regimen is administered every 3 weeks for 4 cycles. Following chemotherapy, patients should receive radiotherapy [ see Dosage and Administration (2.7) ]. Induction Chemotherapy Followed by Chemoradiotherapy (TAX324) For the induction treatment of patients with locally advanced (unresectable, low surgical cure, or organ preservation) SCCHN, the recommended dose of Docetaxel Injection is 75 mg/m 2 as a 1 hour intravenous infusion on day 1, followed by cisplatin 100 mg/m 2 administered as a 30-minute to 3 hour infusion, followed by fluorouracil 1000 mg/m 2 /day as a continuous infusion from day 1 to day 4. This regimen is administered every 3 weeks for 3 cycles. Following chemotherapy, patients should receive chemoradiotherapy [ 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 Docetaxel Injection 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 (5.5) ]. For metastatic castration-resistant 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 Docetaxel Injection infusion [ see Warnings and Precautions (5.5) ]. 2.7 Dosage Adjustments during Treatment Breast Cancer Patients who are dosed initially at 100 mg/m 2 and who experience either febrile neutropenia, neutrophils <500 cells/mm 3 for more than 1 week, or severe or cumulative cutaneous reactions during Docetaxel Injection therapy should have the dosage adjusted from 100 mg/m 2 to 75 mg/m 2 . If the patient continues to experience these reactions, the dosage should either be decreased from 75 mg/m 2 to 55 mg/m 2 or the treatment should be discontinued. Conversely, patients who are dosed initially at 60 mg/m 2 and who do not experience febrile neutropenia, neutrophils <500 cells/mm 3 for more than 1 week, severe or cumulative cutaneous reactions, or severe peripheral neuropathy during Docetaxel Injection therapy may tolerate higher doses. Patients who develop ≥grade 3 peripheral neuropathy should have Docetaxel Injection treatment discontinued entirely. Combination Therapy with Docetaxel Injection in the Adjuvant Treatment of Breast Cancer Docetaxel Injection in combination with doxorubicin and cyclophosphamide should be administered when the neutrophil count is ≥1500 cells/mm 3 . Patients who experience febrile neutropenia should receive G-CSF in all subsequent cycles. Patients who continue to experience this reaction should remain on G-CSF and have their Docetaxel Injection dose reduced to 60 mg/m 2 . Patients who experience grade 3 or 4 stomatitis should have their Docetaxel Injection dose decreased to 60 mg/m 2 . Patients who experience severe or cumulative cutaneous reactions or moderate neurosensory signs and/or symptoms during Docetaxel Injection therapy should have their dosage of Docetaxel Injection reduced from 75 mg/m 2 to 60 mg/m 2 . If the patient continues to experience these reactions at 60 mg/m 2 , treatment should be discontinued. Non-small Cell Lung Cancer Monotherapy with Docetaxel Injection for NSCLC Treatment after Failure of Prior Platinum-Based Chemotherapy Patients who are dosed initially at 75 mg/m 2 and who experience either febrile neutropenia, neutrophils <500 cells/mm 3 for more than one week, severe or cumulative cutaneous reactions, or other grade 3/4 non-hematological toxicities during Docetaxel Injection treatment should have treatment withheld until resolution of the toxicity and then resumed at 55 mg/m 2 . Patients who develop ≥grade 3 peripheral neuropathy should have Docetaxel Injection treatment discontinued entirely. Combination Therapy with Docetaxel Injection for Chemotherapy-Naïve NSCLC For patients who are dosed initially at Docetaxel Injection 75 mg/m 2 in combination with cisplatin, and whose nadir of platelet count during the previous course of therapy is <25,000 cells/mm 3 , in patients who experience febrile neutropenia, and in patients with serious non-hematologic toxicities, the Docetaxel Injection dosage in subsequent cycles should be reduced to 65 mg/m 2 . In patients who require a further dose reduction, a dose of 50 mg/m 2 is recommended. For cisplatin dosage adjustments, see manufacturers' prescribing information. Prostate Cancer Combination Therapy with Docetaxel Injection for Metastatic Castration-Resistant Prostate Cancer Docetaxel Injection should be administered when the neutrophil count is ≥1500 cells/mm 3 . Patients who experience either febrile neutropenia, neutrophils <500 cells/mm 3 for more than one week, severe or cumulative cutaneous reactions or moderate neurosensory signs and/or symptoms during Docetaxel Injection therapy should have the dosage of Docetaxel Injection reduced from 75 mg/m 2 to 60 mg/m 2 . If the patient continues to experience these reactions at 60 mg/m 2 , the treatment should be discontinued. Gastric or Head and Neck Cancer Docetaxel Injection in Combination with Cisplatin and Fluorouracil in Gastric Cancer or Head and Neck Cancer Patients treated with Docetaxel Injection in combination with cisplatin and fluorouracil must receive antiemetics and appropriate hydration according to current institutional guidelines. In both studies, G-CSF was recommended during the second and/or subsequent cycles in case of febrile neutropenia, or documented infection with neutropenia, or neutropenia lasting more than 7 days. If an episode of febrile neutropenia, prolonged neutropenia or neutropenic infection occurs despite G-CSF use, the Docetaxel Injection dose should be reduced from 75 mg/m 2 to 60 mg/m 2 . If subsequent episodes of complicated neutropenia occur the Docetaxel Injection dose should be reduced from 60 mg/m 2 to 45 mg/m 2 . In case of grade 4 thrombocytopenia the Docetaxel Injection dose should be reduced from 75 mg/m 2 to 60 mg/m 2 . 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 . Discontinue treatment if these toxicities persist [ see Warnings and Precautions (5.3) ] . Recommended dose modifications for toxicities in patients treated with Docetaxel Injection in combination with cisplatin and fluorouracil are shown in Table 1. Table 1: Recommended Dose Modifications for Toxicities in Patients Treated with Docetaxel Injection in Combination with Cisplatin and Fluorouracil Toxicity Dosage Adjustment Diarrhea grade 3 First episode: reduce fluorouracil dose by 20%.

Stomatitis/mucositis grade 4 First episode: stop fluorouracil only, at all subsequent cycles. Second episode: reduce Docetaxel Injection dose by 20%. Liver dysfunction: In case of…

8.4 Pediatric Use The alcohol content of Docetaxel Injection should be taken into account when given to pediatric patients [ see Warnings and Precautions (5.13) ]. The efficacy of docetaxel in pediatric patients as monotherapy or in combination has not been established. The overall safety profile of docetaxel in pediatric patients receiving monotherapy or TCF was consistent with the known safety profile in adults. Docetaxel has been studied in a total of 289 pediatric patients: 239 in 2 trials with monotherapy and 50 in combination treatment with cisplatin and 5-fluorouracil (TCF). Docetaxel Monotherapy Docetaxel monotherapy was evaluated in a dose-finding phase 1 trial in 61 pediatric patients (median age 12.5 years, range 1–22 years) with a variety of refractory solid tumors. The recommended dose was 125 mg/m 2 as a 1-hour intravenous infusion every 21 days. The primary dose limiting toxicity was neutropenia. The recommended dose for docetaxel monotherapy was evaluated in a phase 2 single-arm trial in 178 pediatric patients (median age 12 years, range 1–26 years) with a variety of recurrent/refractory solid tumors. Efficacy was not established with tumor response rates ranging from one complete response (CR) (0.6%) in a patient with undifferentiated sarcoma to four partial responses (2.2%) seen in one patient each with Ewing Sarcoma, neuroblastoma, osteosarcoma, and squamous cell carcinoma. Docetaxel in Combination Docetaxel was studied in combination with cisplatin and 5-fluorouracil (TCF) versus cisplatin and 5-fluorouracil (CF) for the induction treatment of nasopharyngeal carcinoma (NPC) in pediatric patients prior to chemoradiation consolidation. Seventy-five patients (median age 16 years, range 9 to 21 years) were randomized (2:1) to docetaxel (75 mg/m 2 ) in combination with cisplatin (75 mg/m 2 ) and 5-fluorouracil (750 mg/m 2 ) (TCF) or to cisplatin (80 mg/m 2 ) and 5-fluorouracil (1000 mg/m 2 /day) (CF). The primary endpoint was the CR rate following induction treatment of NPC. One patient out of 50 in the TCF group (2%) had a complete response while none of the 25 patients in the CF group had a complete response. Pharmacokinetics Pharmacokinetic parameters for docetaxel were determined in 2 pediatric solid tumor trials. Following docetaxel administration at 55 mg/m 2 to 235 mg/m 2 in a 1-hour intravenous infusion every 3 weeks in 25 patients aged 1 to 20 years (median 11 years), docetaxel clearance was 17.3±10.9 L/h/m 2 . Docetaxel was administered in combination with cisplatin and 5-fluorouracil (TCF), at dose levels of 75 mg/m 2 in a 1-hour intravenous infusion day 1 in 28 patients aged 10 to 21 years (median 16 years, 17 patients were older than 16). Docetaxel clearance was 17.9±8.75 L/h/m 2 , corresponding to an AUC of 4.20±2.57 μg∙h/mL. In summary, the body surface area adjusted clearance of docetaxel monotherapy and TCF combination in children were comparable to those in adults [ see Clinical Pharmacology (12.3) ].
