E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The aim of this study is to establish whether or not giving patients the trial drug orteronel (an androgen synthesis blocker) after their disease has been stabilised by chemotherapy (docetaxel), will lengthen the time that they are 'event free' (alive and without evidence of clinical progression of their cancer) in comparison to patients who receive a placebo. |
|
E.2.2 | Secondary objectives of the trial |
This study is looking to determine whether patient's taking orteronel will have a greater quality of life and use less pain control medication than those who have the placebo.
It is looking at the side effects of the study drug. It is also looking at whether those taking the study drug survive longer than those on placebo. |
|
E.2.3 | Trial contains a sub-study | No |

E.4 | Principal exclusion criteria |
• Prior therapy with aminoglutethimide, ketoconazole, orteronel, abiraterone or other modern CYP17 inhibitors • Prior chemotherapy for prostate cancer within 12 months before enrollment except from docetaxel • Retreatment with docetaxel after interruption of > 5 weeks • Concurrent disease requiring higher doses of corticosteroid than the equivalent of 10 mg prednisone per day • Known hypersensitivity to trial drug or hypersensitivity to any of its components • Patient has received other investigational drugs within 30 days before enrollment • Presence of a small cell component in histological specimen • Radiotherapy within the last 2 weeks before expected start of the trial treatment • Known history of central nervous system (CNS) or spinal cord metastases • Current spinal cord compression • Diagnosed or treated for another malignancy within 2 years of registration, with the exception of complete resection of basal cell carcinoma or squamous cell carcinoma of the skin, or any in situ malignancies • History of myocardial infarction, unstable symptomatic ischemic heart disease, ongoing arrhythmias of Grade ≥ 3 (NCI CTCAE version 4.0) or thromboembolic events (e.g., deep vein thrombosis, pulmonary embolism, or symptomatic cerebrovascular events) within 6 months prior to first dose of study drug. Chronic stable atrial fibrillation on stable anticoagulant therapy is allowed • New York Heart Association Class III or IV heart failure • ECG abnormalities of: Q-wave infarction, unless identified ≥ 6 months prior to registration QTc interval > 460 msec • Uncontrolled hypertension despite appropriate medical therapy (blood pressure (BP) of greater than 160 mmHg systolic AND 90 mmHg diastolic at 2 separate measurements no more than 60 minutes apart during the pretreatment evaluation). Note: patients may be rescreened after adjustment of antihypertensive medications. • Likely inability (e.g. due to a psychiatric disorder) to understand information on trial related topics, to give informed consent, to comply with the protocol, to fill in Quality of Life forms and to cooperate fully with the investigator and site personnel • Known gastrointestinal (GI) disease or GI procedure that could interfere with the GI absorption or tolerance of orteronel • Known active chronic hepatitis B or C, life-threatening illness unrelated to cancer, or any serious medical or psychiatric illness that could, in the investigator’s opinion, potentially interfere with participation in this study

E.5 End points |
E.5.1 | Primary end point(s) |
The primary outcome measure is event free survival. An event is defined as one of the following: - death from any cause - the presence of radiographic progression AND symptomatic/clinical progression - the presence of radiographic progression AND PSA progression - the presence of symptomatic/clinical progression AND PSA progression |
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
Patients will be followed up until such a time as their disease has been determined by a clinician to have progressed or they have died.
|
|
E.5.2 | Secondary end point(s) |
The secondary endpoints in the trial will assess: - Adverse events - PSA response (30%, 50%, 90% and best overall response) - Duration of PSA response (50%) - Time to PSA progression - radiographic progression free survival (rPFS) - Quality of Life and pain response - Overall Survival |
|
E.5.2.1 | Timepoint(s) of evaluation of this end point |
Patients will be followed up until death. It is anticipated that all patients will be deceased by 2020. |
