Degarelix
Identification
- Name
- Degarelix
- Accession Number
- DB06699
- Description
Degarelix is used for the treatment of advanced prostate cancer. Degarelix is a synthetic peptide derivative drug which binds to gonadotropin-releasing hormone (GnRH) receptors in the pituitary gland and blocks interaction with GnRH. This antagonism reduces luteinising hormone (LH) and follicle-stimulating hormone (FSH) which ultimately causes testosterone suppression. Reduction in testosterone is important in treating men with advanced prostate cancer. Chemically, it is a synthetic linear decapeptide amide with seven unnatural amino acids, five of which are D-amino acids. FDA approved on December 24, 2008.

Degarelix is a synthetic derivative of GnRH decapeptide, the ligand of the GnRH receptor. Gonadotropin and androgen production result from the binding of endogenous GnRH to the GnRH receptor. Degarelix antagonizes the GnRH receptor which in turn blocks the release of LH and FSH from the pituitary. LF and FSH decreases in a concentration-dependent manner. The reduction in LH leads to a decrease in testosterone release from the testes.
- Mechanism of action
Degarelix competitively inhibits GnRH receptors in the pituitary gland, preventing the release of luteinizing hormone (LH) and follicle stimulating hormone. Reduced LH suppresses testosterone release, which slows the growth and reduces the size of prostate cancers.
Target Actions Organism AGonadotropin-releasing hormone receptor antagonistHumans - Absorption
Degarelix forms a depot at the site of injection after subcutaneous administration from which the drug slowly released into circulation. After a single bolus dose of 2mg/kg, peak plasma concentrations of degarelix occured within 6 hours at a concentration of 330 ng/mL. Ki = 0.082 ng/mL and 93% of receptors were fully suppressed; MRT = 4.5 days.
- Volume of distribution
Central compartment: 8.88 - 11.4 L; Peripheral compartment: 40.9 L
- Protein binding
90% of the drug is bound to plasma proteins.
- Metabolism
70% - 80% of degarelix is subject to peptide hydrolysis during its passage through the hepatobiliary system and then fecally eliminated. No active or inactive metabolites or involvement of CYP450 isozymes.
- Route of elimination
Fecal (70% to 80%) and renal (20%-30% of unchanged drug)
- Half-life
Terminal half-life: 41.5 - 70.2 days; Absorption half-life: 32.9 hours; Half-life from injection site: 1.17 days.
- Clearance
Following subcutaneous administration of degarelix to prostate cancer patients the clearance is approximately 9 L/hr.

The most commonly observed adverse reactions (> 10%) during degarelix therapy included injection site reactions (e.g., pain, erythema, swelling, or induration), hot flashes, increased weight, and increases in serum levels of transaminases and gamma-glutamyltransferase (GGT).
