Brief summary: This is a multicenter, open-label, single-arm study of efficacy, safety and pharmacokinetics of BCD-100 (JSC BIOCAD, Russia) in combination with platinum-based chemotherapy and bevacizumab as first-line treatment in patients with recurrent/persistent or metastatic cervical cancer.

Detailed description: The study will be conducted in two stages. At the first stage patients will receive up to 6 cycles of BCD-100 in combination with platinum-based chemotherapy and bevacizumab or until unacceptable toxicity or disease progression. Patients who have demonstrated a positive antitumor effect (stabilization of the disease, partial or complete response) and who have no signs of unacceptable toxicity could continue to receive up to 12 cycles of maintenance therapy of BCD-100 in combination with bevacizumab or until unacceptable toxicity or disease progression.

Eligibility criteria: Inclusion Criteria:

1. Signed Informed Consent Form and the subject's ability to follow the Protocol requirements;
2. Age: 18 years and older at the signing of the informed consent;
3. Histologically verified (documented) adenomatous, adenosquamous, or squamous cervical cancer;
4. Newly diagnosed metastatic cervical cancer or recurrent/persistent cervical cancer;
5. Availability of archival histological tumor material (paraffin blocks) or consent to biopsy;
6. ECOG performance status of 0 or 1;
7. At least one RESICT 1.1-defined measurable target lesion confirmed by an independent review;
8. Patients with reproductive potential must agree to practice acceptable methods of birth control throughout the entire trial period, starting from signing the informed consent and up to 24 weeks after the last dose of investigational product.

Exclusion Criteria:

1. Indications for radical therapy (surgical or radiotherapy);
2. Prior systemic treatment for recurrent, secondarily progressive or initially metastatic disease;
3. Chemotherapy, and / or radiation therapy, and / or chemo-radiation therapy for early stages of cervical cancer with disease progression / recurrence earlier than 6 months after the end of therapy;
4. Patients with severe concomitant factors or the effects of their treatment (hemorrhage, perforation, fistula);
5. Central nervous system (CNS) metastases;
6. Concomitant diseases or conditions which pose a risk of AE development during study treatment:

   6. severe respiratory failure;
   7. any other diseases which pose unacceptable risk of AE development during study treatment in Investigator's opinion;
7. Active or known or suspected autoimmune disease (subjects with Type 1 diabetes mellitus, hypothyroidism only requiring hormone replacement, or skin disorders (vitiligo, psoriasis, or alopecia) not requiring systemic treatment are permitted to enroll);
8. Condition requiring systemic treatment with either corticosteroids or other immunosuppressive medications within 14 days prior to randomization;
9. Established diagnosis of coagulopathy and / or clinically significant bleeding, including nasal bleeding;
10. The need for regular intake of anticoagulants, antiplatelet agents, platelet function inhibitors, or their course application less than 1 month before being included in the study;
11. Hematologic disorders: neutrophils \<1500/mcl or platelets \<100 000/mcl or hemoglobin \<90 g/l;
12. Renal disorders: creatinine ≥ 1.5 x UNL;
13. Hepatic disorders: bilirubin ≥ 1.5 x UNL (excluding Gilbert's syndrome if bilirubin \< 50 µmol/l) or AST/ALT ≥ 3 x UNL (excluding subjects with liver metastases if AST/ALT \< 5 x UNL) or alkaline phosphatase ≥ 5 x UNL;
14. Any anti-cancer therapy less than 28 days prior to randomization;
15. Previous use of PD-1/PD-L1/PD-L2/CTLA-4 agent;
16. Previous use of VEGF/VEGFR inhibitors, including bevacizumab, ramucirumab, aflibercept and tyrosine kinase inhibitors;
17. Concomitant cancer (except for cervical carcinoma in situ after radical surgery or basal cell/ squamous cell carcinoma after radical surgery);
18. Clinically significant (≥2 degree) peripheral neuropathy or hearing impairment;
19. Any condition that prevents a patient from following the Protocol procedures (dementia, neurological or mental disorders, drug/alcohol abuse, etc.);
20. Simultaneous participation in other clinical trials , participation in other clinical trials within 30 days prior to the first dose of the investigational product;
21. Acute infection or the acute phase of chronic infection within 28 days prior the first dose of the investigational product;
22. Active HBV/HCV/HIV infection, active syphilis;
23. Patients unable to receive an IV infusions;
24. Patients unable to receive an IV contrast agent;
25. Hypersensitivity to any of the components of BCD-100, bevacizumab, paclitaxel, cisplatin (or carboplatin);
26. Life expectancy less than 6 months;
27. Significant adverse events (AE) of previous therapy excluding chronic and/or irreversible events which cannot affect study drug safety evaluation (e.g. alopecia);
28. Pregnancy or breast-feeding.
