Trial Outcomes & Findings for A Study to Assess the Safety of Continued Administration of MDV3100 in Subjects With Prostate Cancer Who Showed Benefit From Prior Exposure to MDV3100 (NCT NCT01534052)

NCT ID: NCT01534052

Last Updated: 2024-12-06

Results Overview

An AE was defined as any untoward medical occurrence in a participant administered study drug or who underwent study procedures and did not necessarily have a causal relationship with treatment. An abnormality identified during a medical test was defined as an AE only if the abnormality induced clinical signs or symptoms, required active intervention, required interruption, or discontinuation of study medication, or was clinically significant in the opinion of the investigator. An AE was defined as serious if it resulted in any of the following outcomes: Death, Was life-threatening, Persistent or significant disability/incapacity or substantial disruption of the ability to conduct normal life functions, Congenital anomaly, or birth defect, Inpatient hospitalization or prolongation of hospitalization, Other medically important event. Drug-related AEs were those assessed by the investigator as AEs whose relationship to the to the study drugs could not be ruled out.

Participant Flow

The study was conducted at 1 site in the Republic of Moldova, 2 sites in South Africa and 4 sites in the United States. In order to participate, participants had to complete a prior study with enzalutamide, be in a state of at least stable disease and benefit from continued treatment with enzalutamide in the opinion of the investigator.

This was an extension study in prostate cancer participants who have received enzalutamide treatment in prior phase 1 studies. The 9785-CL-0121 was an extension of previous enzalutamide studies (9785-CL-0003 \[NCT01902251\], 9785-CL-0007 \[NCT01911728\] \& 9785-CL-0406 \[NCT02225093\]).

PRIMARY outcome

Timeframe: From the date of the first dose of study drug to 30 days after last dose of study drug; the median duration of treatment was 392 days, and the maximum was 1926 days

Population: The analysis population was the SAF.

An AE was defined as any untoward medical occurrence in a participant administered study drug or who underwent study procedures and did not necessarily have a causal relationship with treatment. An abnormality identified during a medical test was defined as an AE only if the abnormality induced clinical signs or symptoms, required active intervention, required interruption, or discontinuation of study medication, or was clinically significant in the opinion of the investigator. An AE was defined as serious if it resulted in any of the following outcomes: Death, Was life-threatening, Persistent or significant disability/incapacity or substantial disruption of the ability to conduct normal life functions, Congenital anomaly, or birth defect, Inpatient hospitalization or prolongation of hospitalization, Other medically important event.
