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-naive 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.
Combination therapy with Docetaxel Injection for metastatic castration-resistant prostate cancer
Docetaxel Injection should be administered when the neutrophil count is ≥1,500 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 >1,500 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.
|Diarrhea grade 3||First episode: reduce fluorouracil dose by 20%. Second episode: then reduce Docetaxel Injection dose by 20%.|
|Diarrhea grade 4||First episode: reduce Docetaxel Injection and fluorouracil doses by 20%. Second episode: discontinue treatment.|
|Stomatitis/mucositis grade 3||First episode: reduce fluorouracil dose by 20%. Second episode: stop fluorouracil only, at all subsequent cycles. Third episode: reduce Docetaxel Injection dose by 20%.|
|Stomatitis/mucositis grade 4||First episode: stop fluorouracil only, at all subsequent cycles. Second episode: reduce Docetaxel Injection dose by 20%.|
In case of AST/ALT >2.5 to ≤5 × ULN and AP ≤2.5 × ULN, or AST/ALT >1.5 to ≤5 × ULN and AP >2.5 to ≤5 × ULN, Docetaxel Injection should be reduced by 20%.
In case of AST/ALT >5 × ULN and/or AP >5 × ULN Docetaxel Injection should be stopped.
The dose modifications for cisplatin and fluorouracil in the gastric cancer study are provided below.
Cisplatin dose modifications and delays
Peripheral neuropathy: A neurological examination should be performed before entry into the study, and then at least every 2 cycles and at the end of treatment. In the case of neurological signs or symptoms, more frequent examinations should be performed and the following dose modifications can be made according to NCI-CTCAE grade:
• Grade 2: Reduce cisplatin dose by 20%.
• Grade 3: Discontinue treatment.
Ototoxicity: In the case of grade 3 toxicity, discontinue treatment.
Nephrotoxicity: In the event of a rise in serum creatinine ≥grade 2 (>1.5 × normal value) despite adequate rehydration, CrCl should be determined before each subsequent cycle and the following dose reductions should be considered (see Table 2).
For other cisplatin dosage adjustments, also refer to the manufacturers’ prescribing information.
|Creatinine clearance result before next cycle||Cisplatin dose next cycle|
|CrCl = Creatinine clearance|
|CrCl ≥60 mL/min||Full dose of cisplatin was given. CrCl was to be repeated before each treatment cycle.|
|Dose of cisplatin was reduced by 50% at subsequent cycle. If CrCl was >60 mL/min at end of cycle, full cisplatin dose was reinstituted at the next cycle.|
|CrCl between 40 and 59 mL/min|
|If no recovery was observed, then cisplatin was omitted from the next treatment cycle.|
|Dose of cisplatin was omitted in that treatment cycle only.|
|If CrCl was still <40 mL/min at the end of cycle, cisplatin was discontinued.|
|CrCl <40 mL/min|
|If CrCl was >40 and <60 mL/min at end of cycle, a 50% cisplatin dose was given at the next cycle.|
|If CrCl was >60 mL/min at end of cycle, full cisplatin dose was given at next cycle.|
Fluorouracil dose modifications and treatment delays
For diarrhea and stomatitis, see Table 1.
In the event of grade 2 or greater plantar-palmar toxicity, fluorouracil should be stopped until recovery. The fluorouracil dosage should be reduced by 20%.
For other greater than grade 3 toxicities, except alopecia and anemia, chemotherapy should be delayed (for a maximum of 2 weeks from the planned date of infusion) until resolution to grade ≤1 and then recommenced, if medically appropriate.
For other fluorouracil dosage adjustments, also refer to the manufacturers’ prescribing information.
Combination Therapy with Strong CYP3A4 Inhibitors
Avoid using concomitant strong CYP3A4 inhibitors (e.g., ketoconazole, itraconazole, clarithromycin, atazanavir, indinavir, nefazodone, nelfinavir, ritonavir, saquinavir, telithromycin and voriconazole). There are no clinical data with a dose adjustment in patients receiving strong CYP3A4 inhibitors. Based on extrapolation from a pharmacokinetic study with ketoconazole in 7 patients, consider a 50% docetaxel dose reduction if patients require coadministration of a strong CYP3A4 inhibitor [see Drug Interactions (7), Clinical Pharmacology (12.3)].
Docetaxel Injection is a cytotoxic anticancer drug and, as with other potentially toxic compounds, caution should be exercised when handling and preparing Docetaxel Injection solutions. The use of gloves is recommended [ see How Supplied/Storage and Handling (16.3)] .
If Docetaxel Injection initial diluted solution, or final dilution for infusion should come into contact with the skin, immediately and thoroughly wash with soap and water. If Docetaxel Injection initial diluted solution, or final dilution for infusion should come into contact with mucosa, immediately and thoroughly wash with water.
Contact of the Docetaxel Injection with plasticized PVC equipment or devices used to prepare solutions for infusion is not recommended. In order to minimize patient exposure to the plasticizer DEHP (di-2-ethylhexyl phthalate), which may be leached from PVC infusion bags or sets, the final Docetaxel Injection dilution for infusion should be stored in bottles (glass, polypropylene) or plastic bags (polypropylene, polyolefin) and administered through polyethylene-lined administration sets.
One-vial Docetaxel Injection
Docetaxel Injection requires NO prior dilution with a diluent and is ready to add to the infusion solution.
Please follow the preparation instructions provided below.
One-vial Docetaxel Injection
Docetaxel Injection (20 mg/mL) requires NO prior dilution with a diluent and is ready to add to the infusion solution. Use only a 21 gauge needle to withdraw docetaxel from the vial because larger bore needles (e.g., 18 and 19 gauge) may result in stopper coring and rubber particulates.
- Docetaxel Injection vials should be stored between 15°C and 25°C (59°F and 77°F).
- Using only a 21 gauge needle, aseptically withdraw the required amount of Docetaxel injection (20 mg docetaxel/mL) with a calibrated syringe and inject via a single injection (one shot) 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 mg/mL to 0.74 mg/mL. If a dose greater than 200 mg of Docetaxel Injection is required, use a larger volume of the infusion vehicle so that a concentration of 0.74 mg/mL Docetaxel Injection is not exceeded.
- Thoroughly mix the infusion by gentle manual rotation.
- As with all parenteral products, Docetaxel Injection should be inspected visually for particulate matter or discoloration prior to administration whenever the solution and container permit. If the Docetaxel Injection dilution for intravenous infusion is not clear or appears to have precipitation, it should be discarded.
- Docetaxel Injection infusion solution is supersaturated, therefore may crystallize over time. If crystals appear, the solution must no longer be used and shall be discarded.
