THERAPEUTIC INDICATIONS
FIRMAGON® is a gonadotrophin releasing hormone (GnRH) antagonist indicated for treatment of adult male patients with advanced hormone-dependent prostate cancer.
POSOLOGY AND METHOD OF ADMINISTRATION
Posology
The first maintenance dose should be given one month after the starting dose.
The therapeutic effect of degarelix should be monitored by clinical parameters and prostate specific antigen (PSA) serum levels. Clinical studies have shown that testosterone (T) suppression occurs immediately after administration of the starting dose with 96% of the patients having serum testosterone levels corresponding to medical castration (T≤0.5 ng/ml) after three days and 100% after one month. Long term treatment with the maintenance dose up to 1 year shows that 97% of the patients have sustained suppressed testosterone levels (T≤0.5 ng/ml).
In case the patient's clinical response appears to be sub-optimal, it should be confirmed that serum testosterone levels are remaining sufficiently suppressed. Since degarelix does not induce a testosterone surge it is not necessary to add an anti-androgen as surge protection at initiation of therapy.
Method of administration
FIRMAGON® must be reconstituted prior to administration. For instructions on reconstitution and administration, please see section Instructions For Use – please refer to the Product Insert/Patient Information Leaflet published on HSA for the full drug information.
FIRMAGON® is for subcutaneous use ONLY, not to be administered intravenously.
Intramuscular administration is not recommended as it has not been studied.
FIRMAGON® is administered as a subcutaneous injection in the abdominal region. The injection site should vary periodically. Injections should be given in areas where the patient will not be exposed to pressure e.g. not close to waistband or belt and not close to the ribs.
Special patient populations
Elderly, hepatically or renally impaired patients:
There is no need to adjust the dose for the elderly or in patients with mild or moderate liver or kidney function impairment (see section Pharmacokinetic Properties – please refer to the Product Insert/Patient Information Leaflet published on HSA for the full drug information). Patients with severe liver or kidney impairment have not been studied and caution is therefore warranted (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).
There is no relevant indication for use of FIRMAGON® in women, children and adolescents.
CONTRAINDICATIONS
Hypersensitivity to the active substance or to any of the excipients.
