Relugolix [Orgovyx] – (Oral GnRH Antagonist)

Introduction

Relugolix, sold under the trade name Orgovyx, is an oral gonadotropin-releasing hormone (GnRH) antagonist used to treat advanced prostate cancer. It offers a convenient alternative to injectable therapies, providing rapid testosterone suppression without the initial testosterone surge (flare) seen with LHRH agonists.

Purpose

  • Treats advanced prostate cancer by lowering testosterone levels.
  • Provides an oral option for androgen deprivation therapy (ADT).
  • Rapidly reduces testosterone without causing a flare, offering a safer alternative for certain patients.

How It Works

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

Usage

  • Taken as an oral tablet, typically once daily.
  • No loading dose is required; testosterone suppression begins rapidly with the first dose.
  • Periodic monitoring of PSA levels, testosterone levels, and overall health is recommended during treatment.

Considerations

  • Common side effects include hot flashes, fatigue, and mild gastrointestinal discomfort.
  • Rare but serious side effects include cardiovascular events and osteoporosis; patients should be monitored closely.
  • Oral administration provides flexibility but requires adherence to daily dosing.
