4.2 Posology and method of administration
All patients must be premedicated prior to paclitaxel administration to reduce the risk of severe hypersensitivity reactions. Such premedication may consist of dexamethasone 20 mg orally (or its equivalent) approximately 12 and 6 hours before paclitaxel or 20 mg I.V. approximately 30 to 60 minutes before paclitaxel, diphenyhydramine 50 mg I.V. (or its equivalent) 30 to 60 minutes prior to paclitaxel and cimetidine (300 mg) or ranitidine (50 mg) I.V 30 to 60 minutes prior to paclitaxel.

Repeat courses of paclitaxel should not be administered to patients with solid tumours until the neutrophil count is at least 1,500 cells/mm³ and the platelet count is at least 100,000 cells/mm³ (<1000 cells/mm³ for patients with Kaposi’s sarcoma). Patients who experience severe neutropenia (<500 cells/mm³) or severe peripheral neuropathy should receive a dosage reduced by 20% for subsequent courses. The incidence of neurotoxicity and the severity of neutropenia increase with dose within a regimen.

Metastatic Carcinoma of the Ovary
Combination therapy: For previously untreated patients, the recommended dosing regimen, given every 3 weeks, is paclitaxel administered intravenously over 3 hours at a dose of 175 mg/m² followed by a platinum compound.

Alternatively, a more myelosuppressive regimen of paclitaxel may also be administered intravenously at a dose of 135 mg/m² over 24 hours followed by a platinum compound, every 3 weeks.

Single-agent therapy: In patients previously treated with chemotherapy the recommended regimen is 175 mg/m² administered intravenously over 3 hours every 3 weeks.

Carcinoma of the Breast
Adjuvant therapy: Paclitaxel 175 mg/m² administered intravenously over 3 hours every 3 weeks for 4 courses sequentially to standard combination therapy.

Single-agent, first-line therapy after relapse within 6 months of adjuvant therapy: Paclitaxel 175 mg/m² administered intravenously over 3 hours every 3 weeks.

Combination, first-line therapy of advanced or metastatic breast cancer: In combination with trastuzumab, the recommended dose of paclitaxel is 175 mg/m² administered intravenously over a period of 3 hours, with a 3-week interval between courses. Paclitaxel infusion may be started the day following the first dose of trastuzumab or immediately after the subsequent doses of trastuzumab if the preceding dose of trastuzumab was well tolerated.

Combination, first-line therapy of metastatic breast cancer: In combination with doxorubicin (50 mg/m²), paclitaxel should be administered 24 hours after doxorubicin. The recommended dose of paclitaxel is 220 mg/m² administered intravenously over a period of 3 hours, with a 3-week interval between courses.

Single-agent second-line therapy after failure of combination chemotherapy for metastatic disease: Paclitaxel 175 mg/m² administered intravenously over 3 hours every 3 weeks.

Non-Small Cell Lung Carcinoma
Combination therapy: For previously untreated patients, the recommended dosing regimen given with a 3 week interval between courses is paclitaxel 175 mg/m² administered intravenously over 3 hours followed by a platinum compound.
Alternatively, a more myelosuppressive regimen of paclitaxel may be administered intravenously 135 mg/m² over 24 hours followed by a platinum compound, with a 3 week interval between courses.

Single-agent therapy: Paclitaxel 175 to 225 mg/m² administered intravenously over 3 hours every 3 weeks.

AIDS-Related Kaposi’s Sarcoma
Second-line therapy: Paclitaxel 135 mg/m² administered intravenously over 3 hours with a 3 week interval between courses or 100 mg/m² administered intravenously over 3 hours with a 2 week interval between courses (dose intensity 45–50 mg/m²/week).

Based upon the immunosuppression observed in patients with advanced HIV disease, the following modifications are recommended in these patients.

1. the dose of dexamethasone as one of the three premedication drugs should be reduced to 10 mg orally

2. treatment with Paclitaxel should be initiated or repeated only if the neutrophil count is at least 1000 cells/mm³

3. the dose of subsequent courses of Paclitaxel should be reduced by 20% for those patients who experience severe neutropenia (<500 cells/mm³ for a week or longer)

4. concomitant hematopoietic growth factor (G-CSF), should be initiated as clinically indicated.

Hepatic Impairment
Patients with hepatic impairment may be at increased risk of toxicity, particularly grade III–IV myelosuppression. Dose adjustment is recommended, as shown in Table 1 for both 3- and 24-hour infusions. Patients should be monitored closely for the development of profound myelosuppression.

Incompatibilities
Contact of the undiluted paclitaxel solutions with plasticized polyvinyl chloride (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, diluted paclitaxel solutions should be stored in bottles (glass, polypropylene) or plastic bags (polypropylene, polyolefin) and administered through polyethylene-lined administration sets. (See Special Instruction for Use, Handling and Disposal section.)

Special Instruction for Use, Handling and Disposal
Paclitaxel is a cytotoxic anti-cancer drug and caution should be exercised in handling paclitaxel. The use of gloves is recommended. If paclitaxel solution contacts the skin, wash the skin immediately and thoroughly with soap and water. If paclitaxel contacts mucous membranes, the membranes should be flushed thoroughly with water. Following topical exposure, events have included tingling, burning and redness. Upon inhalation, dyspnoea, chest pain, burning eyes, sore throat and nausea have been reported. Given the possibility of extravasation, it is advisable to closely monitor the infusion site for possible infiltration during drug administration (see Special Warnings and Precautions for Use: Injection Site Reaction section – please refer to the Product Insert/Patient Information Leaflet published on HSA for the full drug information).

Paclitaxel should be administered through an in-line filter with a microporous membrane not greater than 0.22 microns. Use of filter devices which incorporate short inlet and outlet PVC-coated tubing has not resulted in significant leaching of DEHP.

Dilution should be carried out under aseptic conditions by trained personnel in a designated area. Paclitaxel must be diluted prior to infusion to a final concentration of 0.3 to 1.2 mg/mL. Paclitaxel should be diluted in one of the following: 0.9% Sodium Chloride Injection, 5% Dextrose Injection, 5% Dextrose and 0.9% Sodium Chloride Injection, or 5% Dextrose in Ringer's Injection.

Upon preparation, solutions may show haziness, which is attributed to the formulation vehicle, and is not removed by filtration. Paclitaxel should be administered through an in-line filter with a microporous membrane ≤0.22 micrometre. No significant losses in potency have been noted following simulated delivery of the solution through IV tubing containing an in-line filter.

Paclitaxel solutions should be prepared and stored in glass, polypropylene, or polyolefin containers. Non-PVC containing administration sets, such as those that are polyethylene-lined, should be used. (See Incompatibilities.)

After the final dilution of Ebetaxel Injection Concentrate, the bottle should be swirled gently to disperse the paclitaxel. Do not shake. After dilution the solution is for single use only.

There have been rare reports of precipitation with longer than the recommended 3-hour infusion schedules. Excessive agitation, vibration or shaking may induce precipitation and should be avoided. Infusion sets should be flushed thoroughly with a compatible diluent before use.

Devices with spikes should not be used with vials of paclitaxel since they can cause the stopper to collapse resulting in loss of sterile integrity of the paclitaxel solution.

To reduce microbiological hazard, use as soon as practicable after reconstitution/preparation. If storage is necessary, hold at 2 to 8°C for not more than 24 hours after preparation. Administration should be completed within 24 hours of preparation of the infusion and any residue discarded according to the guidelines for the disposal of cytotoxic drugs (see Handling and disposal below). Excessive agitation, vibration or shaking may induce precipitation and should be avoided. Infusion sets should be flushed thoroughly with a compatible diluent before use.

Procedures for proper handling and disposal of anticancer drugs should be considered.
To minimize the risk of dermal exposure, always wear impervious gloves when handling vials containing paclitaxel. This includes all handling activities in clinical settings, pharmacies, storerooms, and home healthcare settings, including during unpacking and inspection, transport within a facility, and dose preparation and administration.

Handling and disposal
The published guidelines related to procedures for the proper handling and disposal of cytotoxic drugs should be followed.

4.3 Contraindications
Patients is contraindicated in patients who have a history of severe hypersensitivity reactions to paclitaxel or polyoxyl castor oil.

Paclitaxel should not be administered to patients with solid tumours who have baseline neutrophil counts of <1,500 cells/mm³ or in patients with AIDS-related Kaposi’s Sarcoma with baseline or subsequent neutrophil counts of <1000 cells/mm³ (See Posology and Method of Administration section).
