Descrizione dettagliata
High-risk prostate cancer patients are at risk for recurrence after local therapy. The presence of micro-metastatic disease, undetectable by conventional imaging, likely contributes to the poor prognosis. Neoadjuvant hormonal therapy, particularly with the advent of ARPIs like Darolutamide, has shown promise, but patient selection remains crucial for optimizing outcomes. This Phase II, single-arm, open-label trial investigates the predictive value of the PCAI ImmunoScore, a gene expression signature derived from diagnostic biopsies.
100 participants with high-risk prostate cancer scheduled for radical prostatectomy will be enrolled. They will receive Darolutamide (600 mg twice daily) for a period of 90 to 120 days. MRI imaging will be performed between day 90 and 120 prior to surgery. Radical prostatectomy is performed within the same window.
The primary analysis compares the pre-treatment biomarker score with the pathological response (Minimal Residual Disease) observed in the surgical specimen. Secondary analyses include MRI response, PSA kinetics, and patient-reported functional outcomes.

Cosa sta misurando lo studio?
Misure di risultato primarie
Misura del risultato |
Misura Descrizione |
Lasso di tempo |
|---|---|---|
|
The association between the pre-treatment probability of treatment response given by PCAI ImmunoScore and the occurrence of minimal residual disease (MRD)
Lasso di tempo: MRD is ascertained shortly after radical prostatectomy (day 90-120). PCAI ImmunoScore will be ascertained after bulk sequencing of all samples, tentatively 1 year after surgery of the 100th study subject. The association will be calculated thereafter.
|
The primary outcome is the association between the pre-treatment PCAI ImmunoScore and the occurrence of minimal residual disease (MRD) after 90-120 days of neoadjuvant Darolutamide treatment.
MRD is defined as < 0.05 cm3 residual tumour on final pathology after prostatectomy.
The study endpoint MRD will be dichotomized into responder (if MRD is met) or non-responder (if MRD is not met) as input for the statistical data analysis.
This classification (ground truth) will be tested in AUROC analysis against the calculated PCAI ImmunoScore-based probability p (0<p<1) of Darolutamide response.
PCAI ImmunScore is calculated from RNA sequencing of tumor material from diagnostic (pre-treatment) biopsies.
The collection of RNA and calculation of PCAI ImmunoScore will take place after the recruitment period.
Sequencing will be performed in bulk once all samples have been collected.
The objective is to assess the predictive value of the pre-treatment genomic biomarker for pathological response.

MRD is ascertained shortly after radical prostatectomy (day 90-120). PCAI ImmunoScore will be ascertained after bulk sequencing of all samples, tentatively 1 year after surgery of the 100th study subject. The association will be calculated thereafter.

Misura Descrizione |
Lasso di tempo |
|---|---|---|
|
The association between PCAI ImmunoScore and pathologic complete response (pCR)
Lasso di tempo: pCR is ascertained shortly after radical prostatectomy (day 90-120). PCAI ImmunoScore will be ascertained after bulk sequencing of all samples, tentatively 1 year after surgery of the 100th study subject. The association will be calculated thereafter.
|
The study endpoint pCR is defined as no residual tumour visible at final pathology and will be dichotomized into responder (if pCR is met) or non-responder (if pCR is not met) as input for the statistical data analysis.
This classification (ground truth) will be tested in AUROC analysis against the calculated PCAI ImmunoScore-based probability p (0<p<1) (baseline model) of Darolutamide response.
The extended model including the additional covariates will be tested equivalent to the baseline model.
