Premedication Regimen:
All patients should be premedicated with oral corticosteroids such as dexamethasone 16 mg per day (e.g., 8 mg BID) for 3 days starting 1 day prior to Docetaxel administration in order to reduce the incidence and severity of fluid retention as well as the severity of hypersensitivity reactions. For hormone-refractory metastatic 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 infusion.
Breast Cancer: For the prior treatment for breast cancer, the recommended dose of Docetaxel in combination with doxorubicin 50 mg/m
2 is 75 mg/m
2.
The recommended dose of Docetaxel is 60-100 mg/m
2 administered intravenously over 1 hour every 3 weeks for failure of prior chemotherapy.
In the adjuvant treatment of operable node-positive breast cancer, the recommended Docetaxel dose is 75 mg/m
2 administered 1-hour after doxorubicin 50 mg/m
2 and cyclophosphamide 500 mg/m
2 every 3 weeks for 6 courses. Prophylactic G-CSF may be used to mitigate the risk of hematological toxicities.
Non-Small Cell Lung Cancer: The recommended dose is 75-100 mg/m
2 administered intravenously over 1 hour every 3 weeks, 75 mg/m
2 administered intravenously followed by platinum-based chemotherapy.
Prostate Cancer: For hormone-refractory metastatic prostate cancer, the recommended dose of Docetaxel is 75 mg/m
2 every 3 weeks as a 1 hour intravenous infusion. Prednisone 5 mg orally twice daily is administered continuously.
Ovarian Cancer: For the prior treatment of patients with advanced ovarian carcinoma of epithelial, the recommended dose of Docetaxel in combination with carboplatin is 75 mg/m
2 1 hour every 3 weeks intravenous infusion, followed by carboplatin AUC 6.0 mg/mL·min administered intravenously as a 30-minute to 1 hour infusion.
*Amount of Carboplatin is calculated by Calvert Formula: Total dose (mg)=t
AUC x (GFR+25) used with Cockcroft and Gault and Jelliffe formulas for Glomerular Filtration Rate (GFR).*
Head and Neck Cancer: Patients must receive premedication with antiemetics, and appropriate hydration (prior to and after cisplatin administration). Prophylaxis for neutropenic infections should be administered. All patients treated on the Docetaxel containing arms of the TAX323 and TAX324 studies received prophylactic antibiotics.
Induction chemotherapy followed by radiotherapy (TAX323): For the induction treatment of locally advanced inoperable SCCHN, the recommended dose of Docetaxel is 75 mg/m
2 as a 1 hour intravenous infusion followed by cisplatin 75 mg/m
2 intravenously over 1 hour, on day one, followed by fluorouracil as a continuous infusion at 750 mg/m
2 per day for five days. This regimen is administered every 3 weeks for 4 cycles. Following chemotherapy, patients should receive radiotherapy.
Induction chemotherapy followed by chemoradiotherapy (TAX 324): For the induction treatment of patients with locally advanced (unresectable, low surgical cure, or organ preservation) SCCHN, the recommended dose of Docetaxel 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 5-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.
Gastric Adenocarcinoma: The recommended dose of Docetaxel is 75 mg/m
2 as a 1 hour intravenous infusion, followed by cisplatin 75 mg/m
2, as a 1 to 3 hour intravenous infusion (both on day 1 only), followed by fluorouracil 750 mg/m
2 per day given as a 24-hour continuous intravenous infusion for 5 days, starting at the end of the cisplatin infusion. Treatment is repeated every three weeks. Patients must receive premedication with antiemetics and appropriate hydration for cisplatin administration.
Esophageal Cancer: The recommended dose of Docetaxel for adults is 70 mg/m
2 every 3-4 weeks as a 1 hour intravenous infusion once daily.
Dosage Preparation and Administration: Initial Diluted Solution: If the vials are stored under refrigeration, allow the appropriate number of vials of Docetaxel Injection Concentrate and diluent (13% ethanol in water) vials to stand at room temperature for approximately 5 minutes.
Aseptically withdraw the entire contents of the appropriate diluent vial (approximately 1.8 mL for Docetaxel 20 mg and approximately 7.1 mL for Docetaxel 80 mg) into a syringe by partially inverting the vial, and transfer it to the appropriate vial of Docetaxel Injection Concentrate.
Mix the initial diluted solution by repeated inversions for at least 45 seconds to assure full mixture of the concentrate and diluent. Do not shake.
The initial diluted Docetaxel solution (10 mg docetaxel/mL) should be clear; however, there may be some foam on top of the solution due to the polysorbate 80. Allow the solution to stand for a few minutes to allow any foam to dissipate. It is not required that all foam dissipate prior to continuing the preparation process.
The initial diluted solution may be used immediately or stored either in the refrigerator or at room temperature for a maximum of 8 hours.
Final Dilution for Infusion: Aseptically withdraw the required amount of initial diluted Docetaxel solution (10 mg docetaxel/mL) with a calibrated syringe and inject into a 250 mL infusion bag or bottle of either 0.9% Sodium Chloride solution or 5% Dextrose solution to produce a final concentration of 0.3 to 0.74 mg/mL. If a dose greater than 200 mg of Docetaxel is required, use a larger volume of the infusion vehicle so that a concentration of 0.74 mg/mL Docetaxel is not exceeded.
Thoroughly mix the infusion by manual rotation.
As with all parenteral products, Docetaxel should be inspected visually for particulate matter or discoloration prior to administration whenever the solution and container permit. If the Docetaxel initial diluted solution or final dilution for intravenous infusion is not clear or appears to have precipitation, these should be discarded.
The final Docetaxel dilution for infusion should be administered intravenously as a 1-hour infusion under ambient room temperature and lighting conditions.
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 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/m2 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 therapy may tolerate higher doses. Patients who develop ≥grade 3 peripheral neuropathy should have Docetaxel treatment discontinued entirely.
Docetaxel in combination with doxorubicin and cyclophosphamide should be administered when the neutrophil count is ≥1,500 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 dose reduced to 60 mg/m
2. Patients who experience Grade 3 or 4 stomatitis should have their Docetaxel dose decreased to 60 mg/m
2. Patients who experience severe or cumulative cutaneous reactions or moderate neurosensory signs and/or symptoms during Docetaxel therapy should have their dosage of Docetaxel reduced from 75 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: 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 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 treatment discontinued entirely.
For patients who are dosed initially at Docetaxel 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 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: Docetaxel should be administered when the neutrophil count is ≥1,500 cells/mm
3. Patients who experience either febrile neutropenia, neutrophils <500 cells/mm

2. For cisplatin dosage adjustments, see manufacturers' prescribing information.
Gastric or Head and Neck Cancer: Patients treated with Docetaxel in combination with cisplatin and 5-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 GCSF use, the Docetaxel dose should be reduced from 75 to 60 mg/m
2. If subsequent episodes of complicated neutropenia occur the Docetaxel dose should be reduced from 60 to 45 mg/m
2. In case of Grade 4 thrombocytopenia the Docetaxel dose should be reduced from 75 to 60 mg/m
2. Patients should not be retreated with subsequent cycles of Docetaxel until neutrophils recover to a level >1,500 cells/mm
3 and platelets recover to a level >100,000 cells/mm
3. Discontinue treatment if these toxicities persist.
Recommended dose modifications for toxicities in patients treated with Docetaxel in combination with cisplatin and 5-fluorouracil are shown as follows: (see table.)
