OXITAN INJECTION 5MG/ML

[SIN14231P]

Therapeutic indications
Oxaliplatin in combination with 5-fluorouracil (5-FU) and folinic acid (FA) is indicated for:

• Adjuvant treatment of stage III (Duke’s C) colon cancer after complete resection of primary tumour

• Treatment of metastatic colorectal cancer.

Posology and method of administration

Posology
FOR ADULTS ONLY
The recommended dose for oxaliplatin in adjuvant setting is 85 mg/m² intravenously, repeated every two weeks for 12 cycles (6 months).

The recommended dose for oxaliplatin in treatment of metastatic colorectal cancer is 85 mg/m² intravenously, repeated every 2 weeks until disease progression or unacceptable toxicity.

The dose should be adjusted according to tolerability (see section Special warnings and precautions for use – please refer to the Product Insert/Patient Information Leaflet published on HSA for the full drug information).

Oxaliplatin should always be administered before fluoropyrimidines – i.e. 5-fluorouracil (5-FU).

Oxaliplatin is administered as a 2-to 6-hour intravenous infusion in 250 to 500 ml of glucose 5% (50mg/ml) solution to give a concentration between 0.2 mg/ml and 0.70 mg/ml; 0.70 mg/ml is the highest concentration in clinical practice for an oxaliplatin dose of 85 mg/m².

Oxaliplatin has mainly been used in combination with continuous infusion 5-fluorouracil (5-FU) based regimens. For the two-weekly treatment schedule 5-fluorouracil (5-FU) regimens combining bolus and continuous infusion were used.

Special Populations

Renal impairment
Oxaliplatin must not be administered in patients with severe renal impairment (see section Contraindications and Pharmacokinetic properties – please refer to the Product Insert/Patient Information Leaflet published on HSA for the full drug information). In patients with mild to moderate renal impairment, the recommended dose of oxaliplatin is 85 mg/m² (see section Special warnings and precautions for use and Pharmacokinetic properties – please refer to the Product Insert/Patient Information Leaflet published on HSA for the full drug information).

Hepatic insufficiency
In a phase I study including patients with several levels of hepatic impairment, frequency and severity of hepato- biliary disorders appeared to be related to progressive disease and impaired liver function tests at baseline. No specific dose adjustment for patients with abnormal liver function tests was performed during clinical development.

Elderly patients
No increase in severe toxicities was observed when oxaliplatin was used as a single agent or in combination with 5- fluorouracil (5-FU) in patients over the age of 65. In consequence no specific dose adaptation is required for elderly patients.

Paediatric patients
There is no relevant indication for use of oxaliplatin in children. The effectiveness of oxaliplatin single agent in the paediatric populations with solid tumours has not been established (see section Pharmacodynamic properties – please refer to the Product Insert/Patient Information Leaflet published on HSA for the full drug information).

Method of administration
Oxaliplatin is administered by intravenous infusion.

The administration of oxaliplatin does not require hyperhydration.

Oxaliplatin diluted in 250 to 500 ml of glucose 5% (50mg/ml) solution to give a concentration not less than 0.2 mg/ml must be infused via a central venous line or peripheral vein over 2 to 6 hours.

Oxaliplatin infusion must always precede the administration of 5-fluorouracil (5-FU).
In the event of extravasation, administration must be discontinued immediately.

Instructions for use
Oxaliplatin must be diluted before use. Only glucose 5% (50mg/ml) solution is to be used to dilute the injection. (see section Special precautions for disposal and other handling – please refer to the Product Insert/Patient Information Leaflet published on HSA for the full drug information).

• have a known history of hypersensitivity to the active substance or to any of the excipients listed in section List of excipients – please refer to the Product Insert/Patient Information Leaflet published on HSA for the full drug information.

• are breast feeding

• have myelosuppression prior to starting first course, as evidenced by baseline neutrophils < 2 x 10⁹/L and/or platelet count of < 100x 10⁹/L

• have a peripheral sensitive neuropathy with functional impairment prior to first course

• have a severely impaired renal function (creatinine clearance less than 30 ml/min) (see section Pharmacokinetic properties – please refer to the Product Insert/Patient Information Leaflet published on HSA for the full drug information).
