A Study of Abiraterone Acetate (JNJ-212082) and Prednisolone in Patients With Advanced Prostate Cancer
28 februari 2019 uppdaterad av: Janssen Research & Development, LLC
A Phase 2 Open Label Study of Abiraterone Acetate (JNJ-212082) and Prednisolone in Patients With Advanced Prostate Cancer Who Have Failed Androgen Deprivation and Docetaxel-Based Chemotherapy.
The purpose of this study is to assess the safety and efficacy in Korea or Taiwan of oral abiraterone acetate and oral prednisolone in men with metastatic-castration resistant prostate cancer (mCRPC) and with disease progression following treatment with a docetaxel-containing chemotherapy.

Detaljerad beskrivning
This is an open-label (all people know the identity of the intervention), multicenter, single arm (only one treatment group) study to evaluate the efficacy and safety of abiraterone acetate in patients with mCRPC.
The study will be divided into screening phase (up to 28 days before enrollment), treatment phase including treatment cycles (each cycle of treatment will be 28 days), and follow-up phase.
Approximately 80 patients will be enrolled into this study.
Safety evaluations for adverse events, clinical laboratory tests, electrocardiogram and vital signs as well as pharmacokinetic (what the body does to drug) assessments will be conducted in this study.
Patients will continue to receive abiraterone acetate plus prednisolone until disease progression or occurrence of unacceptable toxicity.

Tidsram |
|---|---|---|
|
Percentage of Participants With Prostate-specific Antigen (PSA) Response
Tidsram: Baseline, Month 4
|
The PSA response was evaluated according to Prostate-Specific Antigen Working Group (PSAWG) criterion, which is, greater than or equal to 50 percent decrease in PSA from Baseline during the study, which would be subsequently confirmed by a measurement that is at least 4 or more weeks after initial documentation of PSA response.

Tidsram |
|---|---|---|
|
Overall Survival
Tidsram: Up to 3 Years
|
Overall survival is defined as the time interval from the date of the first dose to the date of death due to any reason.
|
Up to 3 Years
|
|
Time to PSA Progression
Tidsram: Up to 28 Months
|
Time to PSA progression was measured as the time interval from the date of the first dose to the date of PSA progression as defined in the protocol-specific PSAWG criteria.
For participants who have achieved a greater than or equal to (>=) 50% decrease from the baseline PSA, assessment of time to disease progression is when the PSA has increased 50% above the nadir and at a minimum of 5 nanogram/mililiter (ng/mL).
For participants without a PSA decrease of this magnitude or without a decrease, the time for progression is calculated at the time a 25% increase from baseline PSA has been achieved.

Up to 28 Months

Percentage of Participants With Objective Radiographic Response
Tidsram: Up to 3 Years
|
Percentage of participants with radiographic objective response is defined as the percentage of participants with complete response (CR) or partial response (PR) as best overall response based on reconciled radiographic disease assessment according to RECIST Version 1.0.
The CR is disappearance of all lesions.
The PR is at least 30 percent decrease in sum of the longest diameter of target lesions or persistence of one or more non-target lesion(s) or/and maintenance of tumor marker level above the normal limits.

Serum Testosterone
Tidsram: Baseline and End-of-Treatment Visit (up to approximately 3 years)
|
Median serum testosterone concentration was reported at baseline and End-of-Treatment visit.
|
Baseline and End-of-Treatment Visit (up to approximately 3 years)

Dehydroepiandrosterone Sulfate (DHEA-S)
Tidsram: Baseline and End-of-Treatment Visit (up to approximately 3 years)
|
Median DHEA-S concentration was reported at baseline and End-of-Treatment visit.
|
Baseline and End-of-Treatment Visit (up to approximately 3 years)
|
|
Number of Participants With Adverse Events (AEs) and Serious Adverse Events (SAEs)
Tidsram: Up to 3 Years
|
An AE was any untoward medical occurrence in a participant who received study drug without regard to possibility of causal relationship.
An SAE was an AE resulting in any of the following outcomes or deemed significant for any other reason: death; initial or prolonged inpatient hospitalization; life-threatening experience (immediate risk of dying); persistent or significant disability/incapacity; congenital anomaly.
