Main objective
Scope: Efficacy, Therapy
The primary objective of this study is to assess operability in patients with locally advanced T4 high risk prostate cancer upon inductive preprostatectomy
treatment with apalutamide plus ADT for a duration of up to 6 months.
Secondary objectives 6
- to assess the feasibility of treatment
- to assess the effect of the treatment on patients' quality of life
- to characterize PSA levels post-surgery without any further therapy and biochemical complete remission 6 months after surgery
- to describe the time to biochemical recurrence (BCR)
- to assess complete pathological response and negative margin status
- to assess safety and tolerability of treatment

Exclusion criteria 18

- Prior treatment with radiopharmaceutical agents
- Prior chemotherapy for prostate cancer
- History of any pelvic radiation
- Bilateral orchiectomy
- History or evidence of any of the following conditions: any prior malignancy (other than adequately treated basal cell or squamous cell skin cancer, superficial bladder cancer, or any other cancer in situ currently in complete remission) within 5 years prior to enrolment; severe/unstable angina, myocardial infarction, symptomatic congestive heart failure, arterial or venous thromboembolic events, or clinically significant ventricular arrhythmias within 6 months; uncontrolled hypertension; history of seizure or convulsion; gastrointestinal disorder affecting absorption; active infection; and, any other condition that, in the opinion of the investigator, would impair the patient's ability to comply with study procedures
- Presence of any of the following cardiologic criteria: a) Mean resting QTc >470 msec b) In patients with a history of risk factors for QT prolongation and in patients receiving concomitant medicinal products that might prolong the QT interval, the benefit-risk ratio including the potential for Torsade de pointes will be carefully assessed and patients will be excluded if the benefit-risk ratio is considered as unfavorable.

- Patient is eligible for PROTEUS study (all patients with operable, non T4 disease)
- Patient has received another investigational medication (including investigational vaccines) or used another invasive investigational medical device within 30 days before the planned first dose of the IMP of this study or is currently enrolled in another investigational study.
Endpoints
Primary and secondary outcome measures (English text)
Primary endpoints 1
- The prim endpoint of this study is the proportion of pat. with operability - as assessed by MRI , transrectal ultrasound, and clinical examination (two experienced uro oncological surgeons) - upon inductive pre-prostatectomy treatment for a duration of up to 6 months. For patients who have not reached the PSA nadir after the 6-month period and are not considered as operable, the inductive therapy with apalutamide plus ADT can be expanded for a maximum of additiona
Secondary endpoints 17
- Proportion of patients with pT0 (pCR) in prostatectomy specimens (complete pathological response)
- Proportion of patients with negative margin specimen from prostatectomy according to the histology results after surgery
- Proportion of patients with
- Proportion of patients with post-prostatectomy complete biochemical remission (non-detectable serum PSA) 6 months after surgery without hormonal treatment
- Proportion of patients with post-prostatectomy complications requiring surgical re-intervention (Clavien-Dindo IIIB complications, except for interventions aiming at hemostasis only) during the entire postprostatectomy period
- Proportion of patients who achieve PSA nadir upon 6 months of inductive treatment
- Proportion of patients who achieve PSA nadir, prior to surgery
- Change from baseline in FACT-P scores (FACT-P Trial Outcome Index, FACT-G total score, and FACT-P total score) at different study visits.
- Proportion of patients with improvement in their FACT-P scores compared to baseline at different study visits.
- Change from baseline in EQ-5D-3L score at different study visits.
- Proportion of patients with improvement in the EQ-5D-3L score compared to baseline at different study visits.
- Proportion of patients with early (ie, before prostatectomy) PSA relapse from nadir, defined as an absolute PSA increase of more than 10% from the initial PSA value prior to therapy with two PSA rises after 2 consecutive measurements within 2 weeks.
- Proportion of patients with biochemical recurrence (BCR), defined as 2 consecutive PSA values >0.2 ng/mL and rising obtained at two consecutive scheduled study visits after prostatectomy.
- Time to biochemical recurrence (BCR) after prostatectomy, if possible.
- The change in ECOG performance status as well as the change in some hematologic parameters (hemoglobin, leukocytes, lymphocytes, neutrophils, platelets), and the change in levels of serum testosterone/hormones from baseline at different study visits
- Time to treatment discontinuation.
- Safety and tolerability with regard to adverse events (AEs), abnormal laboratory results, and perioperative complications.
