SUGAR: SUrGery With or Without dARolutamide in High-risk and/or Locally Advanced Prostate Cancer
Study Details
Study Description
Brief Summary
This is a phase II, multicenter, randomized open-label and comparative trial designed to study the effectiveness and the safety of androgen receptor antagonist (darolutamide) combined with surgery in patients with high-risk and/or locally advanced prostate cancer.
In this trial, patients will be assigned in one of the two following treatments arms:
-
Arm A (control arm): Surgery alone (radical prostatectomy with lymph node dissection)
-
Arm B (experimental arm): Peri-operative darolutamide + surgery (radical prostatectomy with lymph node dissection)
A total of 240 patients will have to be randomized with 120 patients in the control arm and 120 patients in the experimental arm.

Arms and Interventions
Arm | Intervention/Treatment |
---|---|
Active Comparator: Control arm
|
Other: Surgery alone
Radical prostatectomy with lymph node dissection will be performed.
|
Experimental: Experimental arm
|
Drug: Peri-operative darolutamide + surgery.
Darolutamide: 600 mg (2 tablets of 300 mg) twice daily with food, equivalent to a total daily dose of 1200 mg; for a total duration of 9 months. Darolutamide will start at day 1.
Surgery: radical prostatectomy with lymph node dissection will be performed after at least 3 months of darolutamide treatment.

Outcome Measures
Primary Outcome Measures
- The non-curable progression-free survival (NC-PFS) defined as the time from randomization to non-curable event. [5 years for each patient]
Secondary Outcome Measures
- Metastatic-Free Survival (MFS) defined as the time from randomization to the appearance of distant metastasis or death from any cause. [5 years for each patient]
- PSA-RFS (Recurrence-Free survival) defined as the time from randomization to PSA recurrence according to the European Association of Urology (EAU) criteria or death from any cause. [5 years for each patient]
- Overall Survival (OS) defined as the time from randomization to death from any cause. [5 years for each patient]
- pathological Complete Response (pCR) rate defined as the number of patients presenting a pathological complete response (i.e., absence of residual tumor found in the surgery specimens) divided by the number of patients in the experimental arm. [5 years for each patient]
- Safety assessed using the NCI-CTCAE Version 5.0. [3 years for each patient]
- Quality of life will evaluated using the Functional Assessment of Cancer Therapy-Prostate (FACT-P) questionnaire. [1 year for each patient]
- Quality of life will evaluated using the EQ5D-5L questionnaire. [1 year for each patient]
- Quality of life will evaluated using the International Prostate Symptom Score (IPSS) questionnaire. [1 year for each patient]
- Quality of life will evaluated using the International Index of Erectile Function (IIEF-15) questionnaire. [1 year for each patient]
Eligibility Criteria
Criteria
Inclusion Criteria:
-
Age ≥18 years
-
Histologically confirmed adenocarcinoma of the prostate
-
High-risk and/or locally advanced prostate cancer diagnosis defined by:
One of the following criteria is sufficient to define a high-risk and/or locally advanced prostate cancer:
-
ISUP grade 4 or 5 on biopsies
-
cN1 disease in MRI or PET-Scan
-
T3b disease in MRI
If these criteria are not being identified, two of the following criteria are necessary to define high-risk and/or locally advanced prostate cancer:
-
PSA value >20 ng/ml
-
≥ 50% of the core of biopsies need to be positive for adenocarcinoma ISUP grade 3
-
T3a disease in MRI
-
No distant metastasis confirmed by imaging (i.e., MRI/CT-Scan and Bone Scintigraphy or PET-Scan)
-
Eastern Cooperative Oncology Group (ECOG) Performance Status score of 0-1
-
Patient eligible for radical prostatectomy as per the investigator
-
Adequate organ function within 28 days prior to start of treatment determined by the following central laboratory values:
-
Aspartate aminotransferase (AST), alanine aminotransferase (ALT), and total bilirubin less than the upper limit of normal (ULN; note that in subjects with Gilbert's syndrome, if total bilirubin is >1.5 X ULN, measure direct and indirect bilirubin. If direct bilirubin is ≤1.5 X ULN, the subject may be eligible);
-
Serum creatinine <1.5 mg/dL;
-
Platelets ≥75,000/uL, without transfusion and/or growth factors within 1 month prior to randomization;
-
Hemoglobin >12.0 g/dL (7.4 mmol), without transfusion and/or growth factors within 1 month prior to randomization;
-
Adequate renal function: creatinine clearance/eGFR within normal limits to baseline assessed as per local standard method;
-
Normal cardiac function according to local standard by 12-lead Electrocardiogram (ECG) (complete, standardized 12-lead recording).
-
Patient able to receive darolutamide for up to 9 months as per the investigator
-
Patient able to swallow whole study drug tablets
-
Life expectancy more than 5 years
-
Men should accept (or female partners of men enrolled in the study who are of childbearing potential or are pregnant) to use an effective contraception during darolutamide treatment and at least one week after the end of the investigational product
-
Signed informed consent
-
Patient able to participate and willing to give informed consent prior performance of any study-related procedures and to comply with the study protocol for the duration of the study, including undergoing treatment and scheduled visits and examinations including follow up
-
Patient affiliated to a Social Health Insurance in France.
Exclusion Criteria:
-
Distant metastasis (clinical stage M1). Nodal disease below the iliac bifurcation (clinical stage N1) is not an exclusion.
