First-line Treatment With Camrelizumab + Apatinib Versus Chemotherapy + Bevacizumab in Advanced Cervical Cancer

Study Overview
=================
Brief Summary
-----------------
Cervical cancer is the second-most common cancer in the world and is a leading cause of cancer death among women in developing countries. Cisplatin-based chemotherapy +/- bevacizumab have been recommended as the first-line treatment for patients who present with metastatic (e.g. stage IVB), persistent, or recurrent cervical cancer. However, patients in this setting are rarely curable. The immune checkpoint inhibitor (ICI) therapy, including cytotoxic T-lymphocyte antigen 4 (CTLA-4), programmed death-1 (PD-1), and programmed death-ligand 1 (PD-L1) inhibitors, has revolutionized the treatment of several cancers. The investigator previously reported the promising antitumor efficacy of camrelizumab (PD-1 inhibitor) combined with apatinib (VEGFR2 inhibitor) as second-line, or later, therapy in patients with advanced cervical cancer. This randomized study is to assess the efficacy and safety of first-line treatment with camrelizumab plus apatinib compared to the efficacy and safety of paclitaxel and cisplatin/carboplatin plus bevacizumab in patients with stage IVB, recurrent, or persistent cervical cancer.

Patients with a prior invasive malignancy who have had any evidence of disease within the last 5 years. Exceptions include basal cell carcinoma of the skin, squamous cell carcinoma of the skin, or in situ cervical cancer that has undergone potentially curative therapy. Clinically significant cardiovascular diseases, including but not limited to congestive heart failure (New York heart association (NYHA) class > 2), unstable or severe angina, severe acute myocardial infarction, or cardiac arrhythmia requiring medical intervention within 6 months before enrollment. Prior or concurrent diagnosis of idiopathic pulmonary fibrosis, interstitial pneumonia, pneumoconiosis, radiation pneumonitis, and active pneumonia detected by CT during the screening period. Hypertension that can not be well controlled through antihypertensive drugs (systolic pressure ≥ 140 mm Hg and/or diastolic pressure ≥ 90 mm Hg) Proteinuria ≥ (++) or 24 hours total urine protein > 1.0 g. Patients have coagulation abnormalities with a tendency to bleed or are receiving thrombolytic or anticoagulant therapy. Prophylactic use of aspirin (≤100mg/d), low-molecular-weight-heparin (≤40mg/d), and Rivaroxaban is permitted. Any hemorrhage or bleeding event ≥ CTCAE Grade 2 within 4 weeks prior to the first dose of study intervention; Arterial thrombus or phlebothrombosis within 6 months prior to randomization. Gastrointestinal fistula, bladder/ureteral fistula, or intestinal obstruction within 6 months prior to randomization Has radiation-induced enteritis within 12 months prior to randomization Has received anticancer treatment, including but not limited to radiotherapy, chemotherapy, and surgery within 4 weeks before the first dose of study intervention Any unresolved toxicities (i.e., ≤ Grade 1 or at baseline) from prior therapy, with exception of alopecia; Has an active infection requiring systemic therapy or baseline white blood cells >1.5 × 10 9 / L; Has known active hepatitis B disease (hepatitis B virus [HBV] DNA > 500 IU/ml 1000 copies/ml) or hepatitis C disease; Received prior therapy with an anti-PD-1, anti-PD-L1, or anti-CTLA-4 antibody, apatinib, and bevacizumab. Has a known history of human immunodeficiency virus (HIV) infection; Pregnant or breastfeeding. According to the judgement of the researchers, there are other factors that may lead to the termination of the study.
