Schéma : Brief Summary
The primary objective of this randomized phase II trial is to evaluate the clinical benefits of the addition of atezolizumab to standard chemoradiotherapy (CRT) (first given concurrently with CRT, then continued as adjuvant treatment), compared with CRT alone, on investigator-assessed progression-free survival (PFS), as per Response Evaluation Criteria in Solid Tumors version 1.1 (RECIST v1.1).

Active Comparator: Standard Treatment Arm
Radiotherapy (RT):
Pelvic +/- para-aortic EBRT (IMRT): 45 Gy in 25 fractions over 5 weeks (Weeks 1-5, with simultaneously integrated boosts to macroscopically involved lymph nodes, if any, in order to deliver a total dose of 60 Gy to macroscopic lymph nodes (including the dose delivered by brachytherapy).
Uterovaginal brachytherapy (Week 7; maximum interval between EBRT and brachytherapy: 14 days). If appropriate and feasible, dose escalation will be assumed, particularly for advanced disease, with the objective to deliver a total dose of 85 Gy (equivalent dose in 2-Gy fractions with α/β=10 Gy) to 80% of the High Risk-Clinical Target Volume (HR-CTV), including 45 Gy through EBRT. The total dose might be lower in case of close proximity to organs at risk (OARs).
Total duration of RT (including brachytherapy) should be ≤ 55 days.
Chemotherapy:
- Cisplatin infused 40 mg/m2 (maximum 70 mg) weekly IV during EBRT (Weeks 1-5).

Experimental: Experimental Treatment Arm
Same treatment as described above (CRT, followed by uterovaginal brachytherapy), plus
atezolizumab administered IV 1200 mg Q3W, starting one week before EBRT (Week -1) and continued as an adjuvant for a total maximum of 20 cycles.

Critères d'inclusion et de non-inclusion
Critères d'inclusion : gned informed consent (after informing the patient).
Age between 18 and 70 years.
Histologically confirmed cancer of the uterine cervix: squamous cell carcinoma (SCC), adenocarcinoma, or adenosquamous carcinoma.
At least one evaluable lesion according to RECIST v1.1 criteria for the assessment of the principal judgment criteria.
International Federation of Gynecology and Obstetrics (FIGO) classification (confirmed by both clinical staging and imaging):

(i) stage IB2-IIA tumour with positive pelvic nodal status, as assessed by magnetic resonance imaging (MRI) and/or fluorine-18 fluorodeoxyglucose positron emission tomography (18-FDG PET)/computerised tomography (CT); (ii) stage IIB-IVA tumour, regardless of pelvic lymph node involvement; (iii) stage IVB tumours only if the metastases are limited to the paraaortic lymph nodes.

No evidence of metastatic disease outside the para-aortic area by primary staging (including clinical examination, pelvic MRI, 18-FDG PET, +/- laparoscopic para-aortic lymph node staging).

Eastern Cooperative Oncology Group (ECOG) performance status (PS) of 0 or 1.
Adequate haematologic and end-organ function, defined by the following laboratory results obtained within 15 calendar days prior to the first study treatment:

Absolute neutrophil count (ANC) ≥1,500/mm3 (≥1.5 x 109/L) without granulocyte colony-stimulating factor (G-CSF) support.
Polymorphonuclear neutrophils (PMN) >2,000/mm3 (>2.0 x 109/L).
Lymphocyte count ≥500/mm3 (≥ 0.5 x 109/L)
Platelet count ≥ 100,000/mm3 (≥ 100 x 109/L) without transfusion.
Haemoglobin ≥ 9.0 g/dL (90 g/L; patients may be transfused to meet this criterion).
International Normalized Ratio (INR) and activated partial thromboplastin time (aPTT) ≤ 1.5 × upper limit of normal (ULN) for patients not receiving therapeutic anticoagulation.

Patients receiving therapeutic anticoagulation should be on a stable dose.

Creatinine <1.5 ULN or calculated creatinine clearance (CrCL) ≥ 55 mL/min (calculated using the Cockcroft-Gault formula).
Aspartate transaminase (AST), alanine transaminase (ALT), and alkaline phosphatase <2.5 x ULN.
Serum bilirubin <1.5 x ULN.
Proteinuria < 200 mg/dL (2 g/L).
Ability to comply with the study protocol.
Geographical, social and psychological ability to undergo the followup required by the study.
Women who are not postmenopausal (≥ 12 months of non-therapy induced amenorrhoea) and not surgically sterile:

Must agree to either use an acceptable contraceptive method* or to remain abstinent** (refrain from heterosexual intercourse) during the treatment period and for at least 5 months after the last dose of atezolizumab in arm B and at least 6 months after the last cisplatine dose in arm A.

* Acceptable contraceptive methods include single or combined contraceptive methods that result in a failure rate of < 1% per year, such as: tubal ligation, male sterilization, hormonal implants, established, proper use of combined oral or injected hormonal contraceptives, and certain intrauterine devices. Alternatively, two methods (e.g., two barrier methods such as a condom and a cervical cap) may be combined to achieve a failure rate of < 1% per year. Barrier methods must always be supplemented with the use of a spermicide.

** Abstinence is acceptable only if it is in line with the preferred and usual lifestyle of the patient. Periodic abstinence (e.g., calendar, ovulation, symptothermal, or postovulation methods) and withdrawal are not acceptable methods of contraception.

Must have a negative serum pregnancy test result within 7 days prior to initiation of study drug.
Patients must be affiliated to a social security system or beneficiary of the same, as per local regulatory requirements
