Degarelix [Firmagon] – (GnRH Antagonist)

Introduction

Degarelix, sold under the trade name Firmagon, is a gonadotropin-releasing hormone (GnRH) antagonist used to treat advanced prostate cancer. Unlike LHRH agonists, Degarelix rapidly reduces testosterone levels without causing an initial testosterone surge (flare), making it particularly beneficial for patients at risk of complications from a flare.

Purpose

  • Treats advanced prostate cancer by rapidly suppressing testosterone production.
  • Used in androgen deprivation therapy (ADT) to reduce cancer growth and progression.
  • Offers an alternative to LHRH agonists, especially for patients requiring immediate testosterone suppression.

How It Works

Degarelix blocks GnRH receptors in the pituitary gland, leading to a rapid decrease in luteinizing hormone (LH) and testosterone production. This mechanism bypasses the temporary testosterone surge associated with LHRH agonists.

Usage

  • Administered as a subcutaneous injection, starting with a higher loading dose followed by monthly maintenance doses.
  • Monitoring of PSA levels and testosterone levels is recommended to evaluate efficacy.

Considerations

  • Common side effects include injection site reactions, hot flashes, weight gain, and fatigue.
  • Rare but serious side effects include cardiovascular risks and osteoporosis; patients may require monitoring for these conditions.
  • The absence of a testosterone flare makes it a preferred option for certain patients.
