Overview
Brief Summary
To determine if adjuvant apalutamide in prostate cancer patients at high risk of developing subsequent metastatic disease results in prolonged biochemically recurrence-free survival after radical prostatectomy (RPE) in comparison to standard of care (SOC).

Eligibility Criteria
Inclusion Criteria
- •Signed informed consent form (ICF)
- •Ability to swallow study medication tablets
- •In case of apalutamide treatment: Agrees to use a condom and another highly effective method of birth control if he is having sex with a woman of childbearing potential or to use a condom if he is having sex with a woman who is pregnant
- •Men ≥ 18 years of age
- •Patients with histologically confirmed adenocarcinoma of the prostate after radical prostatectomy
- •Eastern Cooperative Oncology Group (ECOG) performance status grade of 0 or 1
- •Exclusion of metastatic disease by CT-scan of abdomen (MRI of abdomen is possible) and bone scan prior to study inclusion. A PSMA PET-CT/MRI is possible. In this case it has to be done with a diagnostic CT/MRI with contrast media and not with a low dose CT-scan only. In case PSMA-PET imaging has been done, a bone scan can be omitted. CT/MRI, and bone-scan imaging or PSMA PET-CT/MRI administered ≤12 weeks before RPE may be used for screening
- •Patients after RPE must meet the d'Amico criteria for high risk of disease recurrence (T-stage and Gleason-score determined after radical prostatectomy) i.e. 1 of the following after RPE: 1) Gleason score ≥8, any T-stage, any iPSA or 2) Gleason score 6 or 7, any iPSA and ≥pT3 or 3) iPSA >20 ng/ml, any Gleason score, any T-stage.
- •Patients have to have recovered from radical prostatectomy within eight weeks to be able to take part in the study
- •PSA must have declined below 0.2 ng/ml prior to randomization
Exclusion Criteria
- •Any chronic medical condition requiring a higher dose of corticosteroid than 10mg prednisone/prednisolone q.d.
- •Any lymph node or distant metastasis
- •History of seizures or condition that may predispose to seizure (including, but not limited to prior stroke, transient ischemic attack or loss of consciousness ≤1 year prior to randomization; brain arteriovenous malformation; or intracranial masses such as schwannomas and meningiomas that are causing edema or mass effect).
- •Current or prior treatment with anti-epileptic medications for the treatment of seizures
- •Management of cardiovascular risk factors, such as hypertension, diabetes or dyslipidaemia should be optimised as per standard of care before treatment with apalutamide will be initiated 13.
- •Uncontrolled hypertension (systolic BP ≥140 mmHg or diastolic BP ≥90 mmHg. For patients with relevant comorbidities (e.g. diabetes) systolic BP ≥130 mmHg or diastolic BP ≥80 mmHg). Patients with a history of hypertension are allowed provided that blood pressure is controlled by anti-hypertensive treatment 13.
- •Patients with uncontrolled diabetes defined as HbA1c ≥7.5% 13.
- •Patients with a dyslipidemia defined as LDL cholesterol >100 mg/dl. For patients with a dyslipidemia defined as LDL cholesterol >100 mg/dl and SCORE-value of 1-5%: In case of a SCORE-value of <1% a LDL cholesterol level of up to 115 mg/dl is acceptable. In case of increased LDL cholesterol above these values a statin-therapy can be initiated and a rescreening within 4 weeks is possible 13.
- •Cardiovascular risk assessment via an appropriate score (e.g. the SCORE-Chart for the European high/low risk score from the European Society of Cardiology) and ≥ borderline risk i.e. 10% of developing cardiovascular events within 10 years without prior cardiovascular disease
- •Active or symptomatic viral hepatitis or chronic liver disease or HIV
