About this study
Official title: A Randomized, Double-blind, Placebo Controlled Phase III Study of Darolutamide (ODM-201) Versus Placebo in Addition to Standard Androgen Deprivation Therapy and Docetaxel in Patients With Metastatic Hormone Sensitive Prostate Cancer
The purpose of the study is to assess the efficacy and safety of BAY1841788 (darolutamide (ODM-201)) in combination with standard androgen deprivation therapy (ADT) and docetaxel in patients with metastatic hormone sensitive prostate cancer.
Read the detailed description
This is a randomized, double-blind, placebo-controlled, multicenter phase III study. The study population will consist of approximately 1300 subjects with metastatic hormone sensitive prostate cancer (mHSPC), who will be randomized (1:1 ratio) to receive 600 mg (2 x 300 mg tablets) of darolutamide (ODM-201)/placebo twice daily with food, equivalent to a total daily dose of 1200 mg, in addition to standard androgen deprivation therapy (ADT) and docetaxel. Subjects will be stratified at randomization for the extent of disease and for Alkaline Phosphatase levels. All subjects will be treated with ADT as standard therapy. Six cycles of docetaxel will be administered after randomization.
The subjects considered for inclusion in the study will have metastatic prostate cancer and will be candidates for ADT and docetaxel.
Treatment with darolutamide (ODM-201)/placebo will be administered until symptomatic progressive disease, change of antineoplastic therapy, unacceptable toxicity, until subject withdraws consent, withdrawal from the study at the discretion of the investigator or his/her designated associate(s), death, non-compliance, or if sponsor terminates the study.

What is being measured
The primary outcome is the main question the study is designed to answer.
OS From Date of Randomization Until Death From Any Cause - Number of Events
Overall survival (OS) was defined as the time from the date of randomization until death from any cause.
Treatment period: treatment was provided for all patients, twice daily, until disease progression (symptomatic progressive disease, change of systemic antineoplastic therapy), unacceptable toxicity, consent withdrawal, withdrawal at the discretion of the investigator, death, or non-compliance.
Active follow-up visits from the discontinuation of the darolutamide or placebo treatment period for up to 1 year or until the patient could no longer travel to the clinic, died, was lost to follow-up, or withdrew informed consent and actively objected to collection of further data.
Long-term (Survival) follow-up period: After Active follow-up, patients continued to be contacted approximately every 12 weeks by phone. The end of the Survival follow-up period was defined as when the patient died, was lost to follow-up, withdrew consent, or at the end-of-study.
Measured: From randomization of the first participant until death from any cause up to 25 OCT 2021 cut-off date 533 OS events were reached (approximate 59 months)
OS From Date of Randomization Until Death From Any Cause - Month
Treatment period: treatment was provided for all patients, twice daily, until disease progression (symptomatic progressive disease, change of systemic antineoplastic therapy), unacceptable toxicity, consent withdrawal, withdrawal at the discretion of the investigator, death, or non-compliance.
Active follow-up visits from the discontinuation of the darolutamide or placebo treatment period for up to 1 year or until the patient could no longer travel to the clinic, died, was lost to follow-up, or withdrew informed consent and actively objected to collection of further data.
Long-term (Survival) follow-up period: After Active follow-up, patients continued to be contacted approximately every 12 weeks by phone. The end of the Survival follow-up period was defined as when the patient died, was lost to follow-up, withdrew consent, or at the end-of-study.
Median, percentile and other 95% CIs were computed using Kaplan-Meier estimates.
NA = Value cannot be estimated due to censored data
Measured: From randomization of the first participant until death from any cause up to 25 OCT 2021 cut-off date 533 OS events were reached (approximate 59 months)
Secondary outcomes (15)
Number of Participants With TEAEs
TEAEs = Treatment-emergent adverse events, were defined as any event(s) arising or worsening after the first dose of darolutamide or placebo, until 30 days after the last dose of darolutamide or placebo administration.
Measured: From the first dose of darolutamide or placebo until 30 days after the last dose of darolutamide or placebo administration up to cut-off date for the final completion analysis 11 APR 2023 (approximately 77 months)
Time to Castration-Resistant Prostate Cancer (CRPC) - Number of Events
Time to castration-resistant prostate cancer was defined as the time from randomization to the first occurrence of one of the following events: PSA progression, Radiological progression by bone lesions, or Radiological progression by soft tissue and visceral lesions.
Treatment period: until disease progression (symptomatic progressive disease, change of systemic antineoplastic therapy), unacceptable toxicity, consent withdrawal, withdrawal at the discretion of the investigator, death, or non-compliance.

- No: Availability of this study's data will later be determined according to Bayer's commitment to the EFPIA/PhRMA "Principles for responsible clinical trial data sharing". This pertains to scope, timepoint and process of data access. As such, Bayer commits to sharing upon request from qualified researchers patient-level clinical trial data, study-level clinical trial data, and protocols from clinical trials in patients for medicines and indications approved in the US and EU as necessary for conducting legitimate research. This applies to data on new medicines and indications that have been approved by the EU and US regulatory agencies on or after January 01, 2014. Interested researchers can use www.vivli.org to request access to anonymized patient-level data and supporting documents from clinical studies to conduct research.
