Informations complémentaires
Schéma : In this randomized 2:1 phase II trial of Stereotactic Body Radiation Therapy with or without durvalumab in oligometastatic hormone sensitive prostate cancer patients, Durvalumab will be started one month prior to SBRT to be able to evaluate PSA and immune response to the drug. It will be combined with SBRT and then given adjuvantly for a total of 12 months.

2 arms:
- Experimental: Radiation (SBRT) + Immunotherapy treatment (Durvalumab)
64 patients will be enrolled in this arm
Durvalumab will be started one month prior to SBRT and then given for a total of 12 months.
Patient will receive one injection per months (1500 mg/cycle)
SBRT will be started one month after Durvalumab and patients will receive 3 fractions of radiation

- Active Comparator: Radiation (SBRT)
32 patients will be enrolled in this arm
Patients will receive only 3 fractions of radiation

Phase : II

Stade : Métastatique

Critères d'inclusion et de non-inclusion
Critères d'inclusion : - Written informed consent obtained from the patient prior to performing any protocol-related procedures, including screening evaluations
- Age > or = 18 years at time of study entry
- Histologically proven diagnosis of prostate cancer (PCa)
- PCa patients with a biochemical recurrence "Rising PSA" following treatment with curative intent (radical prostatectomy, primary radiotherapy or a combination of both) as defined by the EAU guidelines.
- A maximum of 5 bone or lymph node metastases, seen only on FCH-PET CT or Ga-PSMA PET CT, not seen on conventional imaging assessments (bone scan or thorax, abdomen and pelvis CT scan).
- WHO performance state 0-1
- Controlled primary tumor. In case the PSA > 0,2 ng/ml in the postoperative setting patients are eligible if a multiparametic MRI or PET scan of the prostate bed rules out a local relapse.
Patients after primary radiotherapy should undergo MRI of the prostate according to the European Society of Urogenital Radiology (ESUR) guidelines to rule out local relapse. In case of a suspicious lesion, a biopsy should confirm local recurrence and patients should be referred for local salvage prostatectomy when distant metastases are ruled out. If MRI rules out local relapse, patients are eligible.
- If ADT has been previously administered to the patient, a minimum of 12 months must have elapsed between the predicted duration of the last injection and inclusion of the patient in the study. For this category of patients, serum testosterone has to be higher than 8.5 nmol/l prior to inclusion.
- Adequate normal organ and marrow function as defined below:
-> Haemoglobin ≥9.0 g/dL
-> Absolute neutrophil count (ANC) ≥ 1.5 x 103 /L (≥ 1500 per mm3)
-> Platelet count ≥ 75 x 109/L (≥75,000 per mm3)
-> Serum bilirubin ≤1.5 x institutional upper limit of normal (ULN). This will not apply to patients with confirmed Gilbert's syndrome (persistent or recurrent hyperbilirubinemia that is predominantly unconjugated in the absence of hemolysishaemolysis or hepatic pathology), who will be allowed only in consultation with their physician.
-> AST (SGOT)/ALT (SGPT) ≤2.5 x institutional upper limit of normal unless liver metastases are present, in which case it must be ≤5x ULN
-> Measured creatinine clearance (CL) ≥ 40 ml/min or Calculated creatinine CL ≥ 40 ml/min by the Cockcroft-Gault formula (Cockcroft and Gault 1976) or by 24-hour urine collection for determination of creatinine clearance: Creatinine CL (ml/min) = Weight (kg) x (140 - Age) 72 x serum creatinine (mg/dL)
- Body weight > 30kg
- Life expectancy of > 24 months.
- Patient is willing and able to comply with the protocol for the duration of the study including undergoing treatment and scheduled visits and examinations including follow up.
- Social insurance

Critères de non-inclusion : - Serum testosterone level < 8.5 nmol/ml
- Vertebral metastases with a minimum distance inferior to 5 mm between GTV (gross tumor volume) and spinal cord
- Visceral metastases
- Bone metastases seen on bone scan
- Lymph nodes greater than 20 mm
- PSA doubling time less than 6 months
- Spinal cord compression
-Any unresolved toxicity NCI CTCAE (v4.03) Grade ≥2 from previous anticancer therapy with the exception of alopecia, vitiligo, and the laboratory values defined in the inclusion criteria
-> Patients with Grade ≥2 neuropathy will be evaluated on a case-by-case basis after consultation with the Study Physician.
-> Patients with irreversible toxicity not reasonably expected to be exacerbated by treatment with durvalumab may be included only after consultation with the Study Physician.
- PSA rise while on active treatment (LHRH-agonist, LHRH-antagonist, anti-androgen, maximal androgen blockade, oestrogen)
- Lung, Brain, Liver or other visceral metastases
- Relapsed primary tumor
- Perihilar lymphnode metastases
- Previous irradiation of the oligometastatic site using a dose > 20 Gy less than 5 years ago.
- Previous treatment with a cytotoxic agent for PCa
- Treatment during the past month with products known to influence PSA levels (e.g. fluconazole, finasteride, corticosteroids...)
- Participation in another clinical study with an investigational product during the last 4 weeks
- Concurrent enrolment in another clinical study, unless it is an observational (non-interventional) clinical study or during the follow-up period of an interventional study
- Any prior immune therapy (CTLA-4, PD1 (Programmed cell death )1 or PD-L1 inhibitor, including durvalumab)
- Current or prior use of immunosuppressive medication within 14 days before the first dose of durvalumab, with the exceptions of intranasal and inhaled corticosteroids or systemic corticosteroids at physiological doses, which are not to exceed 10 mg/day of prednisone, or an equivalent corticosteroid. The following are exceptions to this criterion:
-> Intranasal, inhaled, topical steroids, or local steroid injections (e.g., intra articular injection)
-> Systemic corticosteroids at physiologic doses not to exceed 10 mg/day of prednisone or its equivalent
-> Steroids as premedication for hypersensitivity reactions (e.g., CT scan premedication)
- Radiotherapy treatment to more than 30% of the bone marrow or with a wide field of radiation within 4 weeks of the first dose of study drug

The following are exceptions to this criterion:
-> Patients with vitiligo or alopecia
-> Patients with hypothyroidism (e.g., following Hashimoto syndrome) stable on hormone replacement
-> Any chronic skin condition that does not require systemic therapy
-> Patients without active disease in the last 5 years may be included but only after consultation with the study physician

Patients with a past or resolved HBV (hepatitis B virus) infection (defined as the presence of hepatitis B core antibody [anti-HBc (hepatitis B core antigen)] and absence of HBsAg) are eligible. Patients positive for hepatitis C (HCV) antibody are eligible only if polymerase chain reaction is negative for HCV RNA.
- Receipt of live attenuated vaccine within 30 days prior to the first dose of immunotherapy. Note: Patients, if enrolled, should not receive live vaccine whilst receiving immunotherapy and up to 30 days after the last dose of immunotherapy.
