This study examines the drug Degarelix, given with or without Apalutamide (ARN-509) before surgery (radical prostatectomy), in patients with intermediate- and high-risk prostate cancer. It was open to men aged 18 to 80 with intermediate- or high-risk prostate adenocarcinoma. It was conducted in Phase 2 and is currently not recruiting but ongoing (active, not recruiting).
The summary above is a plain-language rendering of the official record. The original English title is shown for reference.
Criteria are reproduced from the ClinicalTrials.gov record in the original English. Only the trial team can determine eligibility.
Inclusion Criteria: 1. Absence of any psychological, familial, sociological or geographical condition potentially hampering compliance with the study protocol and follow-up schedule; those conditions should be discussed with the patient before registration in the trial 2. Before patient registration/randomization, written informed consent must be given according to ICH/GCP, and national/local regulations 3. Male aged 18 years or older (within 80 years) 4. Histologically confirmed adenocarcinoma of the prostate without neuroendocrine differentiation or small cell features 5. Diagnosis of intermediate (at least 2 of the following factors: cT2b, biopsy GS 7, PSA 10-20ng/ml) or high-risk prostatic adenocarcinoma (clinical stage≥T2c and/or biopsy GS≥8 and/or PSA\>20ng/ml), cN0-cN1, cM0. 6. Patient amenable for open or robotic radical prostatectomy + pelvic lymph node dissection 7. ECOG performance status: 0-1 8. Adequate organ function as defined by the following criteria: * White blood cells (WBC) ≥ 4.0 x109/L * Platelet count ≥ 100 x109/L * Hemoglobin ≥9 g/dl * Creatinine ≤ 2 x ULN * Serum aspartate transaminase (AST; serum glutamic oxaloacetic transaminase \[SGOT\]) and serum alanine transaminase (ALT; serum glutamic pyruvic transaminase \[SGPT\]) ≤ 2.5 x upper limit of normality (ULN) * Total serum bilirubin ≤1.5 x ULN. Exclusion Criteria: 1. Previous surgical/endoscopic treatments for prostatic disease 2. Herbal and non-herbal products that in the opinion of the investigator may decrease PSA levels 3. cM1 disease 4. Any contraindication for PET or MR investigations 5. History of seizure or condition that may pre-dispose to seizure (e.g., prior stroke within 1 year prior to randomization, brain arteriovenous malformation, Schwannoma, meningioma, or other benign CNS or meningeal disease which may require treatment with surgery or radiation therapy) 6. Medications known to lower the seizure threshold 7. History of: * Any prior malignancy (other than adequately treated basal cell or squamous cell skin cancer, superficial bladder cancer currently in complete remission) within 5 years prior to randomization * Severe/unstable angina, myocardial infarction, symptomatic congestive heart failure, arterial or venous thromboembolic events (e.g., pulmonary embolism, cerebrovascular accident including transient ischemic attacks), or clinically significant ventricular arrhythmias within 6 months prior to randomization * Uncontrolled hypertension (systolic blood pressure ≥160 mmHg or diastolic BP ≥100 mmHg). Patients with a history of uncontrolled hypertension are allowed provided blood pressure is controlled by anti-hypertensive treatment. * Gastrointestinal disorder affecting absorption 8. Any other condition that, in the opinion of the Investigator, would impair the patient's ability to comply with study procedures.
