Initial staging procedures performed no more than 56 days prior to the first dose of CCRT. 6. Provision of FFPE tumor sample to assess the PD-L1 expression. 7.

Diagnosis of small cell (neuroendocrine) or mucinous adenocarcinoma of cervical cancer. 2. Evidence of metastatic disease. 3. Intent to administer a fertility-sparing treatment regimen. 4. History of organ transplant or allogenic stem cell transplant. 5. History of active primary immunodeficiency or active or prior documented autoimmune or inflammatory disorders. 6. Uncontrolled intercurrent illness. 7. History of another primary malignancy except for a) Malignancy treated with curative intent with no known active disease ≥2 years before the first dose of study intervention; b) Adequately treated nonmelanoma skin cancer or lentigo maligna, or carcinoma in situ without evidence of disease. 8. Unresolved toxicities from previous CCRT except for irreversible toxicity that is not reasonably expected to be exacerbated. 9. Prior history or presence of vesicovaginal, colovaginal, or rectovaginal fistula. 10. History of anaphylaxis to any biologic therapy or vaccine. 11.

Patients who have undergone a previous hysterectomy, including a supracervical hysterectomy, or will have a hysterectomy as part of their initial cervical cancer therapy. 13. Any prior (besides prior CCRT) or concurrent treatment for cervical cancer. 14. Major surgical procedures within 4 weeks prior to the first dose of the study intervention or still recovering from prior surgery. 15. Exposure to immune mediated therapy prior to the study for any indication. 16. Receipt of live attenuated vaccine within 30 days prior to the first dose of the study intervention. 17. Participants with a known allergy or hypersensitivity to the study intervention, or any excipients of the study intervention.
