Introduction: Prostate cancer has increased in recent years, increasing the costs associated with its treatment. Second-generation oral antiandrogens have emerged as an attractive therapeutic option.

Objective: To compare the health value provided by enzalutamide and apalutamide, by evaluating two stages of prostate cancer: non-metastatic castration-resistant prostate cancer (nmCRPC) and metastatic hormone-sensitive prostate cancer (mHSPC).

Methods: To establish, through the American Society of Clinical Oncology (ASCO) value framework, a contrast between two technologies in two stages of prostate cancer. The monthly cost of the two technologies was calculated according to the current price regulation norm in Colombia.

Results: Enzalutamide showed a higher net health benefit score compared to apalutamide for both nmCRPC (48.33 versus 33.46) and mHSPC (52.0 versus 40.75). The cost per net health benefit point for the nmCRPC stage was $214,723 Colombian Pesos (COP) ($54.84 USD) with enzalutamide compared to $291,925 COP ($74.56 USD) with apalutamide, and for the mHSPC stage was $199,692 COP ($51.00 USD) with enzalutamide and $239,701 COP ($61.22 USD) with apalutamide.

Conclusion: After comparing enzalutamide versus apalutamide in the nmCRPC and mHSPC stages through the ASCO value framework, enzalutamide showed a more prominent net clinical benefit and a lower investment per point awarded.
