Brief Summary

Prospective, multicenter, comparative, randomized placebo-controlled Phase III trial - patients with hormone-naïve prostate cancer and pelvic lymph nodes metastases

Detailed Description

Standard of care for patients with prostate cancer (PC) with pelvic lymph nodes metastases is radiotherapy (RT) with long-term androgen deprivation therapy (ADT). . Darolutamide improves survival in men with castration-refractory non metastatic prostate cancer. We hypothesize that adding Darolutamide to ADT and RT could improve FFS for these high-risk patients.

12. Written informed consent.

13. Willing and expected to comply with follow-up schedule.

14. Affiliated to the social security system.

15. Use of 5-α reductase inhibitors (finasteride, dutasteride) is allowed

Exclusion Criteria

1. Lymph nodes metastases outside of the pelvis

2. Bone or visceral metastases

3. Prior systemic therapy for locally-advanced prostate cancer except for LH-RH agonist or antagonist up to 3 months before randomization

4. Prior treatment with:

• Second generation AR inhibitors such as enzalutamide, apalutamide (ARN-509), darolutamide (ODM-201) other investigational AR inhibitors
• CYP17 enzyme inhibitor such as abiraterone acetate, TAK-700 or
• Oral ketoconazole
• Use of estrogens, or AR inhibitors (bicalutamide, flutamide, nilutamide, cyproterone acetate)

5. Use of systemic corticosteroid with dose greater than the equivalent 10 mg of prednisone/day within 28 days before randomization.

6. Patients with QTor QTc interval > 450 ms on the ECG

7. Initiation of treatment with bisphosphonate or denosumab within 12 weeks before randomization. Patients receiving bone loss prevention treatment on a stable dose of e.g. bisphosphonate or denosumab for at least 28 days before randomization can continue the treatment during the study.

8. Known hypersensitivity to the study treatment (RT, ADT, darolutamide/placebo) or any of its ingredients.

9. Major surgery within 28 days before randomization.

10. Any of the following within 6 months before randomization: stroke, myocardial infarction, severe/unstable angina pectoris, coronary/peripheral artery bypass graft; congestive heart failure New York Heart Association (NYHA) Class III or IV or arterial thromboembolic event.

11. Uncontrolled hypertension as indicated by a resting systolic BP > 160 mmHg or diastolic BP > 100 mmHg at screening. Patients may be re-screened after adjustments of anti- hypertensive medications.

12. Prior malignancy. Adequately treated basal cell or squamous cell carcinoma of skin or superficial bladder cancer that has not spread behind the connective tissue layer (i.e. pTis, pTa, and pT1) is allowed, as well as any other cancer for which chemotherapy has been completed > 5 years ago and from which the patient has been disease-free.

13. Gastrointestinal disorder or procedure which expects to interfere significantly with absorption of study treatment.

14. Active viral hepatitis, active human immunodeficiency virus (HIV) or chronic liver disease.
