3. Able (in the investigator's judgment) to comply with the study protocol
4. GOG/Eastern Cooperative Oncology Group (ECOG) performance status of 0-1
5. Life expectancy 3 and more months
6. Histologically- or cytologically-confirmed diagnosis of metastatic (stage IVB), persistent, or recurrent cervical cancer (histologies other than squamous cell, adenocarcinoma, or adenosquamous will be excluded) not amenable for curative treatment with surgery and/or radiation therapy. The inclusion of patients with adenocarcinoma histology will be capped to 20% of the whole study population.
7. No prior systemic anti-cancer therapy for metastatic or recurrent disease.
- Concurrent chemo-radiotherapy treatment with curative intent or adjuvant chemo-radiotherapy must have been completed 3 and more months (90 days) prior to enrollment
- Palliative radiation therapy (e.g., for pain or bleeding) 6 weeks prior enrollment is allowed as long as this does not affect measurable disease and patients are recovered from its symptoms.
8. Measureable disease by RECIST v1.1 criteria: Patients must have at least 1 target lesion to be used to assess response on this protocol as defined by RECIST v1.1. If the only target lesion is limited to the radiation field, a biopsy is required to confirm malignancy.
9. A tumor specimen is mandatory at study entry. This may be an archival biopsy or, in its absence, a tumor biopsy obtained within 3 months of randomization from a non-irradiated lesion. Paired recent biopsies at baseline (lesion not previously irradiated; within 3 months of randomization) and at progression disease will not be mandatory, nevertheless they are encouraged as long as these are feasible.

11. Adequate liver function:
- Serum albumin 2.5 g/dL and more
- Total serum bilirubin 1.5xULN and less
- AST and ALT 2.5xULN and less or 5xULN and more if tumor involvement (liver) is present
12. Adequate renal function:
- Patients with serum creatinine less than 1.5xULN
- Urine dipstick for proteinuria less than 2+. Patients discovered to have 2+ proteinuria on dipstick urinalysis at baseline should undergo a 24-hour urine collection and must demonstrate 1 and more g of protein in 24 hours or urine protein/creatinine (UPC) ratio of 1.0
13. Adequate coagulation:
- Blood coagulation parameters (PTT, PT/INR): PT such that international normalized ratio (INR) is 1.5 (or an in-range INR, usually between 2 and 3, if a patient is on a stable dose of therapeutic warfarin for management of venous thrombosis including pulmonary thromboembolus) and PTT less than 1.5xULN
14. Negative Test Results for Hepatitis
15. Toxicities related to previous treatments must be recovered to less than grade 2 (with the exception of alopecia).
16. Female participants must be postmenopausal (12 and more months of non-therapyinduced amenorrhoea) or surgically sterile (absence of ovaries and/or uterus, or who received therapeutic radiation to the pelvis) or otherwise have a negative serum pregnancy test within 7 days of the first study treatment and agree to abstain from heterosexual intercourse or use single or combined contraceptive methods that result in a failure rate of less than 1% per year during th

Exclusion Criteria

1.Disease that is suitable for local therapy administered with curative intent
2.Prior radiotherapy delivered using cobalt (rather than a linear accelerator)
3.Patients with Stage IVA not amenable to concurrent chemo-radiation as primary treatment will not be eligible.
4.Ongoing disease involving the bladder or rectum at screening/baseline:
- In patients with pelvic disease, absence of tumor in the bladder or rectal mucosa must be demonstrated by MRI (preferred method, or endoscopy/cystoscopy if MRI is not easily accessible) within 28 days before enrolment
5.Evidence of abdominal free air
6.Bilateral hydronephrosis, unless it can be alleviated by ureteral stent(s) or percutaneous drainage
7.Patients previously treated with chemotherapy except when used concurrently with radiation therapy. Patients who have received either concurrent paclitaxel with radiation therapy or carboplatin/paclitaxel as neoadjuvant or adjuvant therapy are ineligible for the study.
8.Prior treatment with any anti-VEGF drug, including bevacizumab, CD137 agonists or immune checkpoint blockade therapies, anti-PD1, or anti-PDL1 therapeutic antibodies or anti-CTLA 4.
9.Patients with a concomitant malignancy other than non-melanoma skin cancer. Patients with a prior invasive malignancy (except non-melanoma skin cancer) who have had any evidence of disease within the last 5 years or whose prior malignancy treatment contraindicates the current protocol therapy.
10.Known brain metastases or spinal cord compression. It is mandatory to perform a scan of the brain in cases of suspected brain metastases (CT or MRI) or spinal cord compression (MRI).
11.History or evidence, following a neurological examination, of central nervous system disorders, unless properly treated with standard medical treatment. History of cerebrovascular accident, transient ischemic attack or subarachnoid hemorrhage within six months of the first date of treatment on this study.
12.Patients with serious non-healing wound, ulcer, or bone fracture. This includes history of abdominal fistula, gastrointestinal perforation or intra-abdominal abscess for which an interval of 6 months must pass before study entry. In addition, the patient must have undergone correction (or spontaneous healing) of the perforation/fistula and/or the underlying process causing the fistula/perforation.

Study & Design

Study Type: Interventional

Study Design: Not specified

Primary Outcome Measures

Name	Time	Method
- Progression free survival (PFS) based on investigator assessment using the Response Evaluation Criteria in Solid Tumors version 1.1 (RECIST v1.1).<br>- Progression Free Survival (PFS) is the period from study entry (day of randomization) until disease progression, death or date of last contact. Progression will be based on tumor assessment made by the investigators according to the RECIST v1.1. criteria. Patients who had not experienced an event at the data cut-off date or patients who are withdrawn from the study without documented progression will be censored at the date of the last tumor assessment when the patient was known to be progression free. Patients without a known post baseline tumor assessments but known to be alive will be censored at the time of randomization date.<br>- Overall Survival (OS), defined as the observed length of life from entry into the study (day of randomization) to death or the date of last contact.

Secondary Outcome Measures

Name	Time	Method
- Objective Response Rate (ORR) as assessed by RECIST v1.1 <br>- Duration of response (DOR) by RECIST v1.1 <br>- Frequency and severity of adverse events as assessed by CTCAE version 5.0 for the regimens administered on this study. <br>- Time from randomization to first subsequent therapy or death (TFST) <br>- Time from randomization to second progression (PFS2) based on radiologic assessment, start of a new line of therapy, symptomatic deterioration or death. <br>- Mean and mean changes from baseline score in patient function (role, physical) and GHS/HRQoL, by assessment timepoint and between treatment arms, as assessed by the functional and GHS/HRQoL scales of EORTC QLQ-C30. <br>- Serum concentration (Cmin and Cmax) of atezolizumab at specified timepoints. Incidence of ATAs during the study relative to the prevalence of ATAs at baseline. <br>- Prevalence of ATAs to atezolizumab at baseline and incidence of ATAs to atezolizumab during the study.
