DOCEFREZ (Page 2 of 8)

2.8 Administration Precautions

DOCEFREZ is a cytotoxic anticancer drug and, as with other potentially toxic compounds, caution should be exercised when handling and preparing DOCEFREZ solutions. The use of gloves is recommended. Please refer to [see How Supplied/ Storage and Handling (16.3)].
If DOCEFREZ lyophilized powder, reconstituted solution, or infusion solution should come into contact with the skin, immediately and thoroughly wash with soap and water. If DOCEFREZ lyophilized powder, reconstituted solution or infusion solution should come into contact with mucosa, immediately and thoroughly wash with water.
Contact of the DOCEFREZ reconstituted solution 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 DOCEFREZ infusion solution should be stored in bottles (glass, polypropylene) or plastic bags (polypropylene, polyolefin) and administered through polyethylene-lined administration sets.
DOCEFREZ (Lyophilized Powder for Injection and Diluent)
DOCEFREZ for Injection requires reconstitution with Diluent and one further dilution with infusion solution prior to administration. Please follow the preparation instructions provided below.The table below provides the fill range of the Diluent, the volume of Diluent to be added for the reconstitution and the concentration of the reconstituted solution for DOCEFREZ 20 mg and DOCEFREZ 80 mg (See Table 1).

Docetaxel 80 mg vial 4.13 – 4.29 mL 4 mL 24 mg/mL

2.9 Preparation and Administration

DOCEFREZ (Lyophilized Powder for Injection and Diluent)
A. Preparation of the Reconstituted Solution

  1. DOCEFREZ vials should be stored between 2°C and 8°C (36°F and 46°F). Allow the appropriate number of vials of DOCEFREZ (docetaxel) for Injection and diluent (35.4% ethanol in polysorbate 80) vials to stand at room temperature for approximately 5 minutes.
  2. a) For DOCEFREZ 20: Use 1 mL syringe with needle of 18- to 21-gauge, 1½-inch for withdrawing diluent for DOCEFREZ 20.
    b) For DOCEFREZ 80: Use 4 mL syringe with needle of 18- to 21-gauge, 1½-inch for withdrawing diluent for DOCEFREZ 80.
  3. a) For DOCEFREZ 20: Aseptically withdraw 1 mL from the diluent vial into a syringe by partially inverting the vial, and transfer it to product vial of DOCEFREZ (docetaxel) for Injection.
    b) For DOCEFREZ 80: Aseptically withdraw 4 mL from the diluent vial into a syringe by partially inverting the vial, and transfer it to product vial of DOCEFREZ (docetaxel) for Injection .
  4. Shake the reconstituted vial well in order to completely dissolve the docetaxel powder present in the vial. For the 20 mg vial, the resultant concentration is 20 mg/0.8 mL. For the 80 mg vial, the resultant concentration is 24 mg/mL .

The reconstituted DOCEFREZ solution should be clear; however, there may be some air bubbles in the solution due to the polysorbate 80. Allow the solution to stand for a few minutes to allow any air bubbles to dissipate.
The reconstituted solution may be used immediately or stored either in the refrigerator or at room temperature for a maximum of 8 hours.
B. Preparation of the Infusion Solution

  1. Aseptically withdraw the required amount of reconstituted DOCEFREZ solution 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 DOCEFREZ is required, use a larger volume of the infusion vehicle so that a concentration of 0.74 mg/mL docetaxel is not exceeded.
  2. Thoroughly mix the infusion by manual rotation.
  3. Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration, whenever solution and container permit. If the DOCEFREZ reconstituted solution or infusion solution is not clear or appears to have precipitation, these should be discarded.
  4. DOCEFREZ reconstituted solution is supersaturated, therefore may crystallize over time. If crystals appear, the solution must no longer be used and shall be discarded.

The final DOCEFREZ infusion solution should be administered intravenously as a 1-hour infusion under ambient room temperature (below 25° C) and lighting conditions.

2.10 Stability

DOCEFREZ infusion solution, if stored between 2°C and 25°C (36°F and 77°F) is stable for 6 hours. DOCEFREZ infusion solution (in either 0.9% Sodium Chloride solution or 5% Dextrose solution) should be used within 6 hours (including the 1 hour intravenous administration). In addition, physical and chemical in-use stability of the infusion solution prepared as recommended has been demonstrated in non-PVC bags up to 48 hours when stored between 2°C and 8°C (36°F and 46°F).

4 CONTRAINDICATIONS

  • DOCEFREZ is contraindicated in patients who have 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 (5.4)].
  • DOCEFREZ should not be used in patients with neutrophil counts of <1,500 cells/mm3.

5 WARNINGS AND PRECAUTIONS

5.1 Toxic Deaths

Breast Cancer
DOCEFREZ administered at 100 mg/m2 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/m2 , 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 CancerDOCEFREZ administered at a dose of 100 mg/m2 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/m2 dose in the randomized trials. Among patients who experienced treatment-related mortality at the 75 mg/m2 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 combined abnormalities of transaminases and alkaline phosphatase should not be treated with DOCEFREZ [see Boxed Warning, Use in Specific Populations (8.6), Clinical studies (14)].

5.3 Hematologic Effects

Perform frequent peripheral blood cell counts on all patients receiving DOCEFREZ. Patients should not be retreated with subsequent cycles of DOCEFREZ until neutrophils recover to a level > 1,500 cells/mm3 and platelets recover to a level > 100,000 cells/mm3.
A 25% reduction in the dose of DOCEFREZ is recommended during subsequent cycles following severe neutropenia (<500 cells/mm3) lasting 7 days or more, febrile neutropenia, or a grade 4 infection in a DOCEFREZ cycle [see Dosage and Administration (2.7)].
Neutropenia (<2000 neutrophils/mm3) occurs in virtually all patients given 60 mg/m2 to 100 mg/m2 of docetaxel and grade 4 neutropenia (<500 cells/mm3) occurs in 85% of patients given 100 mg/m2 and 75% of patients given 60 mg/m2. Frequent monitoring of blood counts is, therefore, essential so that dose can be adjusted. DOCEFREZ should not be administered to patients with neutrophils <1,500 cells/mm3.
Febrile neutropenia occurred in about 12% of patients given 100 mg/m2 but was very uncommon in patients given 60 mg/m2. Hematologic responses, febrile reactions and infections, and rates of septic death for different regimens are dose related [see Adverse Reactions (6.1), Clinical Studies (14)].Three breast cancer patients with severe liver impairment (bilirubin >1.7 times ULN) developed fatal gastrointestinal bleeding associated with severe drug-induced thrombocytopenia. [see Dosage and Administration (2.7), Adverse Reactions (6)].
