A Phase 2 Study to Evaluate Safety and Efficacy of Abiraterone in Participants With Prostate Cancer

19 ottobre 2017 aggiornato da: Janssen Research & Development, LLC

A Phase II Study of JNJ-212082 (Abiraterone Acetate) in Metastatic Castration Resistant Prostate Cancer Patients Who Are Chemotherapy-Naïve

The purpose of this study is to investigate safety and efficacy of abiraterone in participants with metastatic castration-resistant prostate cancer (mCRPC) and who have not received prior chemotherapy (treatment of disease, usually cancer, by chemical agents).

Descrizione dettagliata

This is a multi-center (conducted in more than one center), open-label (all people know the identity of the intervention), single-arm study to investigate safety and efficacy of abiraterone. The study consists of 3 phases: Screening phase (consists of 14 days before study commences on Day -1); Treatment phase (consists of 28-daily dosing cycles wherein abiraterone 1000 milligram [mg] once daily along with 5 mg prednisolone twice daily will be given until disease progression or unacceptable toxicity is observed); and Follow-up phase (up to 5 years or until survival after the first dose of study drug). Abiraterone will be orally administered daily as at least 1 hour before the meal or 2 hours after the meal. Dose reduction will be allowed at the Investigator's discretion but not lower than 500 mg per day. Participants will discontinue study treatment at disease progression unless, in the Investigator's opinion, it is deemed that the participants will continue to derive benefit from abiraterone. Efficacy will be evaluated primarily through decline in prostate-specific antigen (substance in blood that is measured to check for prostate cancer) after 12 weeks of therapy. Participants' safety will be monitored throughout the study.

Cosa sta misurando lo studio?

Misure di risultato primarie

Misura del risultato
Misura Descrizione
Lasso di tempo
Percentage of participants achieving Prostate-Specific Antigen (PSA) response up to 12 weeks
Lasso di tempo: Baseline up to 12 weeks
The PSA response will be evaluated according to Prostate-Specific Antigen Working Group (PSAWG) criterion, which is, greater than or equal to 50 percent decrease in PSA from Baseline up to 12 weeks after the first dose of study drug, which would be subsequently confirmed by a measurement that is at least 4 or more weeks after initial documentation of PSA.
Baseline up to 12 weeks

Misure di risultato secondarie

Clinical Benefit is defined as a confirmed complete response (CR), confirmed partial response (PR), or stable disease (SD) 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. The SD is neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for progressive disease since treatment started.
