Neoadjuvant Chemotherapy Plus Camrelizumab for FIGO Stage IB1 Cervical Cancer

Neoadjuvant Chemotherapy Plus Camrelizumab (NACI Therapy) for Fertility Preservation in FIGO Stage IB1 Cervical Cancer

This multicenter, prospective clinical trial is designed to enroll PD-L1 expression-positive patients with stage IB1 cervical cancer who desire fertility preservation to undergo neoadjuvant chemotherapy in combination with a PD-1 inhibitor to evaluate the rate of complete pathologic remission, treatment-related adverse events, pregnancy rate, miscarriage rate, preterm birth rate, live birth rate, EFS and OS.

3. Transformation zone of TZ1 or TZ2 (IFCPC 2011);
4. Positive PD-L1 expression by preoperative pathology, i.e., Combined Positive Score (CPS) ≥1;
5. Patient age ≥18 years and ≤45 years;
6. ECOG score ≤1;
7. Laboratory tests: white blood cell (WBC) ≥3. 5×109/L, Neutrophil (NEU) ≥1. 5×109/L, platelet (PLT) ≥100×109/L, serum bilirubin ≤1.5 times the upper limit of normal, aminotransferase ≤1.5 times the upper limit of normal, and blood urea nitrogen （BUN) and Cr ≤normal;
8. Have a strong desire to give birth;
9. Willing to sign the informed consent form, including compliance with the requirements and restrictions listed in the informed consent form and program.

4. History of human immunodeficiency virus (HIV) infection or known active hepatitis B or C;
5. Use of immunosuppressive drugs or systemic corticosteroid therapy for immunosuppression (>10 mg/day prednisone or equivalent) within 2 weeks prior to study dosing;
6. History of primary malignancy or receipt of chemotherapy or pelvic radiation;
7. Concurrent participation in other clinical trials;
8. Pregnant or breastfeeding female patients; subjects must agree to use effective contraception during study treatment, within 5 months of last use of immune check inhibitors, within 6 months of last use of chemotherapeutic agents, and if there is no confirmation that the lesion has been removed or that the pathology is in remission;
9. Uncontrolled co-morbidities, including but not limited to New York Heart Association (NYHA) class 2 or higher, severe/unstable angina pectoris, myocardial infarction within ≤ 6 months prior to study drug administration, severe arrhythmias requiring medication or intervention; difficult-to-control hypertension; and cerebral vascular accidents or brain disorders within ≤ 6 months prior to study drug administration, or those with adjudicated abnormal behavioral skills; hematologic disorders: coagulation abnormalities (INR > 2. 0, Prothrombin time (PT) > 16s), bleeding tendency, or undergoing thrombolytic or anticoagulant therapy; abnormalities in hepatic or renal development or a history of surgery; and any active infection requiring systemic anti-infective therapy within 14 days prior to the first dose of study drug;
