ARCHES Trial Summary

This trial studied whether adding the drug enzalutamide to androgen deprivation therapy (ADT) could help treat men with metastatic hormone-sensitive prostate cancer (mHSPC).

Who is the study for?
Adult men with advanced prostate cancer that has spread, who can take pills and follow the study rules. They must have a good performance status (able to carry out daily activities), no history of certain types of prostate cancer or brain metastasis, normal organ function, and not have had certain treatments for their cancer recently.Check my eligibility
What is being tested?
The trial is testing if adding enzalutamide to standard hormone therapy slows down cancer growth better than a placebo plus hormone therapy in men whose prostate cancer has spread but haven't received chemotherapy for it.See study design
What are the potential side effects?
Enzalutamide may cause fatigue, back pain, constipation, joint pain, hot flushes. It can also affect blood pressure and could lead to falls or fractures. Rarely it might cause seizures.

ARCHES Trial Design

3Treatment groups
Experimental Treatment
Placebo Group
Group I: Placebo followed by EnzalutamideExperimental Treatment1 Intervention
Eligible participants who received enzalutamide matching placebo during double-blind treatment period and provided informed consent to take part in open-label period switched to receive 160 mg enzalutamide orally once daily in open-label period until disease progression, unacceptable toxicity or any other discontinuation criteria were met. ADT (either bilateral orchiectomy or LHRH agonist/antagonist) was maintained during study treatment as per standard of care and provided by the site's pharmacy stock.
Group II: Enzalutamide + Androgen Deprivation Therapy (ADT)Experimental Treatment1 Intervention
Participants received 160 mg enzalutamide orally once daily during double-blind treatment period until radiographic progression was documented or until the participants started an investigational agent or new therapy for treatment of prostate cancer or until any other discontinuation criterion was met. Eligible participants who received enzalutamide during double-blind treatment period and provided informed consent to take part in open-label period continued to receive 160 mg enzalutamide orally once daily in open-label period until disease progression, unacceptable toxicity or any other discontinuation criteria were met. ADT (either bilateral orchiectomy or Luteinizing hormone-releasing hormone (LHRH) agonist/antagonist) was maintained during study treatment as per standard of care and provided by the site's pharmacy stock.
Group III: Placebo + Androgen Deprivation Therapy (ADT)Placebo Group1 Intervention
Participants received matching placebo orally once daily during double-blind treatment period until radiographic progression was documented or until the participants started an investigational agent or new therapy for treatment of prostate cancer or until any other discontinuation criterion was met. ADT (either bilateral orchiectomy or LHRH agonist/antagonist) was maintained during study treatment as per standard of care and provided by the site's pharmacy stock.
