Is an LHRH antagonist a better first-line hormone therapy than an LHRH agonist?

The question of whether an LHRH antagonist (such as degarelix) is really a better first-line hormone therapy than an LHRH agonist (e.g., leuprolide acetate) is still not fully answered.

Degarelix as second-line ADT in men not responsive to LHRH agonist therapy

First-line androgen deprivation therapy (ADT) for a man with metastatic prostate cancer has long been been either surgical or medical castration. In the case of medical castatration, the form of medication most commonly used since the mid to late 1980s has been an LHRH agonist (e.g., leuprolide acetate).

Are all LHRH agonists “just the same”?

When all the drugs in the same class have the same general clinical impact, this is known as a “class effect.” As an example, all statins (hydroxymethylglutaryl–coenzyme A reductase inhibitors) will lower risk for certain types of cardiovascular event because they lower levels of cholesterol. That is a “class effect.”

Efficacy and safety of the LHRH antagonist degarelix

Klotz et al. have now published the complete results of one of the Phase III clinical trials designed to evaluate the effectiveness and the safety of degarelix — a second-generation LHRH antagonist — in the management of hormone-sensitive prostate cancer.
