What is Firmagon?
From the FDA label:FIRMAGON is a sterile lyophilized powder for injection containing degarelix (as the acetate) and mannitol. Degarelix is a synthetic linear decapeptide amide containing seven unnatural amino acids, five of which are D-amino acids. The acetate salt of degarelix is a white to off-white amorphous powder of low density as obtained after lyophilization. The chemical name of degarelix is D-Alaninamide, N -acetyl-3-(2-naphthalenyl)-D-alanyl-4-chloro-D-phenylalanyl-3-(3-pyridinyl)-D-alanyl-L-seryl-4-[[[(4S)-hexahydro-2,6-dioxo-4-pyrimidinyl]carbonyl]amino]-L phenylalanyl-4-[(aminocarbonyl)amino]-D-phenylalanyl-L-leucyl- N 6–(1-methylethyl)-L-lysyl-L-prolyl. It has an empirical formula of C 82 H 103 N 18 O 16 Cl and a molecular weight of 1632.3 Da. Degarelix acetate has the following structural formula: FIRMAGON is available in two packaging configurations: Starting Dose: Two vial carton with each vial delivering 120 mg of degarelix (equivalent to the median value of 126 mg degarelix acetate). Each 120 mg dose contains 150 mg mannitol. Maintenance Dose: One-vial carton delivering 80 mg of degarelix (equivalent to the median value of 84 mg degarelix acetate). Each 80 mg dose contains 200 mg mannitol. Chemical Structure
How to use
FIRMAGON is for subcutaneous use only Starting Dosage: 240 mg given as two injections of 120 mg each ( 2.1 ) Maintenance Dosage: 80 mg administered as a single injection every 28 days ( 2.1 ) 2.1 Dosing information FIRMAGON is administered as a subcutaneous injection in the abdominal region only at the dosages in Table 1 below. Table 1: FIRMAGON Recommended Dosages Starting Dosage Maintenance Dosage – Administered once every 28 days 240 mg given as two subcutaneous injections of 120 mg at a concentration of 40 mg/mL The first maintenance dose should be given 28 days after the starting dose. 80 mg given as one subcutaneous injection at a concentration of 20 mg/mL 2.2 Reconstitution and Administration Instructions FIRMAGON is to be administered by a healthcare professional only . Before administering FIRMAGON read the Instructions for reconstitution and administration carefully. As with other drugs administered by subcutaneous injection, the injection site should vary periodically. Injections should be given only in areas of the abdomen that will not be exposed to pressure, e.g., not close to waistband or belt nor close to the ribs. FIRMAGON is supplied as a powder to be reconstituted with Sterile Water for Injection, USP. Starting dose (240 mg): Two single-dose vials each delivering 120 mg of degarelix in a white to off-white lyophilized powder for reconstitution supplied with…
Side effects
Most common adverse reactions (≥10%) are injection site reactions (e.g., pain, erythema, swelling or induration), hot flashes, and increases in serum levels of transaminases and gamma-glutamyltransferase (GGT) ( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact Ferring at 1-888-FERRING (1-888-337-7464) or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch . 6.1 Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice. FIRMAGON was studied in a randomized, open-label trial in which patients with prostate cancer were randomized to receive FIRMAGON (subcutaneous) or leuprolide (intramuscular) monthly for 12 months [see Clinical Studies (14) ] . The most common adverse reactions (≥10%) during FIRMAGON therapy are injection site reactions (e.g., pain, erythema, swelling or induration), hot flashes, and increases in serum levels of transaminases and gamma-glutamyltransferase (GGT). The majority of the adverse reactions were Grade 1 or 2, with Grade 3/4 adverse reaction incidences of 1% or less. Adverse reactions reported in ≥ 5% of patients treated with FIRMAGON (subcutaneous) 240 mg starting dose and then 80 mg maintenance dose once every 28 days or who…
Warnings
Important safety information
Hypersensitivity: Anaphylaxis, urticaria and angioedema have been reported. Discontinue FIRMAGON if a severe hypersensitivity reaction occurs and manage as clinically indicated ( 5.1 ) QT Interval Prolongation: Androgen deprivation therapy treatment with FIRMAGON may prolong the QT interval. ( 5.2 ) Embryo-Fetal Toxicity: FIRMAGON can cause fetal harm. ( 5.4 , 8.1 ) 5.1 Hypersensitivity Reactions FIRMAGON is contraindicated in patients with history of severe hypersensitivity to degarelix or to any of the product components [see Contraindications (4) ]. Hypersensitivity reactions, including anaphylaxis, urticaria and angioedema, have been reported post-marketing with FIRMAGON. In case of a severe hypersensitivity reaction, discontinue FIRMAGON immediately if the injection has not been completed, and manage as clinically indicated. Patients with a known history of severe hypersensitivity reactions to FIRMAGON should not be re-challenged with FIRMAGON. 5.2 QT Interval Prolongation Androgen deprivation therapy may prolong the QT interval. Providers should consider whether the benefits of androgen deprivation therapy outweigh the potential risks in patients with congenital long QT syndrome, congestive heart failure, frequent electrolyte abnormalities, and in patients taking drugs known to prolong the QT interval. Electrolyte abnormalities should be corrected. Consider periodic monitoring of electrocardiograms and electrolytes. In the randomized, active-controlled trial comparing FIRMAGON to leuprolide, periodic electro-cardiograms were performed. Seven patients, three (<1%) in the pooled degarelix group and four (2%) patients in the leuprolide 7.5 mg group, had a QTcF ≥ 500 msec. From baseline to end of study, the median change for FIRMAGON was 12.3 msec and for leuprolide was 16.7 msec. 5.3 Laboratory Testing FIRMAGON results in suppression of the pituitary gonadal system. Results of diagnostic tests of the pituitary gonadotropic and gonadal functions conducted during and after FIRMAGON may be affected. The therapeutic effect of FIRMAGON should be monitored by measuring serum concentrations of prostate-specific antigen (PSA) periodically. If PSA increases, serum concentrations of testosterone should be measured. 5.4 Embryo-Fetal Toxicity Based on findings in animal studies, FIRMAGON can cause fetal harm and loss of pregnancy when administered to a pregnant woman. In animal developmental and reproductive toxicity studies in rats and rabbits, oral administration of degarelix during organogenesis caused embryo-fetal lethality and abortion as well as increased post-implantation loss and decreased the number of live fetuses in animals at doses less than the clinical loading dose based on body surface area. Advise pregnant patients and females of reproductive potential of the potential risk to the fetus [see Use in Specific Populations (8.1) ].
Who should not take Firmagon
FIRMAGON is contraindicated in patients with history of severe hypersensitivity to degarelix or to any of the product components [see Warnings and Precautions (5.1) ] . Patients with history of severe hypersensitivity reactions to degarelix or to any of the product components ( 4 )
Overdose — what happens if you take too much
There have been no reports of overdose with FIRMAGON. In the case of overdose, however, discontinue FIRMAGON, treat the patient symptomatically, and institute supportive measures.

Interactions
No drug-drug interaction studies were conducted. Degarelix is not a substrate for the human CYP450 system. Degarelix is not an inducer or inhibitor of the CYP450 system in vitro . Therefore, clinically significant CYP450 pharmacokinetic drug-drug interactions are unlikely.
