Detailed Description
Multicentric randomized non-comparative, open-label, phase II trial, based on signle-stage design, to assess the preliminary signs of antitumor activity of darolutamide plus radiation therapy in patients with unfavorable intermediate risk prostate cancer.
Patients satisfying eligibility criteria will be randomized according to 2 treatment modalities
-
Arm A (experimental arm): combination of external beam radiotherapy (EBRT) and 6 months darolutamide.
-
Arm B (standard arm): combination of external beam radiotherapy (EBRT) and 6 months ADT (androgen deprivation therapy)
Two patients randomized in arm A for one patient randomized in arm B.
Study Design

|---|---|
| Experimental: Experimental Arm A: combination of radiotherapy and darolutamide Patients with unfavorable intermediate risk prostate cancer will be treated with darolutamide for a maximum of 6 months combined with external beam radiotherapy |
Drug: Association of darolutamide and EBRT
Darolutamide will be taken orally at a fixed dose of 600 mg twice daily (1200 mg), on a continuous basis, for a maximum of 6 months. Darolutamide will start at Day 1.
- External Beam Radiotherapy (EBRT) will start two months after treatment initiation. All patients will be treated with standard schedules:
78 Gy with classical 2 Gy/fractions, 5 days/7
Or 60 Gy with 3 Gy/fractions, 5 days/7

Treatment by Androgen Deprivation Therapy (ADT) will be prescribed as per market authorization and following investigator judgement. ADT treatment will consist on:
Either LH-RH agonist injection given every 3 months for 6 months, or once for 6 months,
Either LH-RH antagonist given monthly for 6 months
