E.2 Objective of the trial

E.2.1

Main objective of the trial

To assess if neoadjuvant therapy with pembrolizumab is associated with pathologic changes at radical prostatectomy and with a reduction in the rate of lymph node invasion in prostate cancer patients at high risk of recurrence after surgery.

Valutare se la somministrazione di pembrolizumab in neoadiuvante induce una risposta patologica e riduce il rischio di invasione linfonodale nei pazienti con tumore della prostata ad alto rischio candidati a intervento chirurgico

E.2.2

Secondary objectives of the trial

- To evaluate radiological response in terms of reduction of tumour volume at preoperative mpMRI on those patients with measurable disease at baseline. Radiological response will be defined as a tumour reduction of 30% in the maximum diameter of the index lesion as measured by mpMRI
- To test the impact of neoadjuvant pembrolizumab on the risk positive surgical margins at final pathology
- To test the impact of neoadjuvant pembrolizumab on the risk of PSA persistence after surgery
- To assess the safety and side effects of pembrolizumab in PCa patients undergoing surgery

- Valutare la risposta radiologica al trattamento con pembrolizumab definita come una riduzione del 30% del volume tumorale alla mpMRI
- Valutare se la somministrazione di pembrolizumab riduce il rischio di margini chirurgici positivi
- Valutare se la somministrazione di pembrolizumab riduce il rischio di persistenza di elevati valori di PSA dopo chirurgia
- Determinare la sicurezza e gli effetti collaterali della somministrazione di pembrolizumab nei pazienti con tumore della prostata

E.5 End points

E.5.1

Primary end point(s)
