Exclusion Criteria:

• Other malignant tumors that have appeared or are currently present within 5 years, except for cured cervical carcinoma in situ, non-melanoma skin cancer and superficial bladder tumors;

• Has received prior therapy with an anti-PD-1, anti-PD-L1, or anti PD-L2 agent or with an agent directed to another stimulatory or co-inhibitory T-cell receptor (e.g. cytotoxic T-lymphocyte-associated protein 4 [CTLA-4], OX 40, CD137);

• Has received prior therapy with tyrosine kinase inhibitors that target VEGFR, such as pazopanib, sorafenib, regorafenib, apatinib and other drugs; but previous bevacizumab treatment is allowed (only for ovarian cancer cohorts), provided that the treatment is stopped for more than 4 weeks before enrollment;

• Has received prior radiotherapy within 4 weeks prior to enrollment (participants must have recovered from all radiation-related toxicities, not require corticosteroids, and not have had radiation pneumonitis - a 2-week washout is permitted for palliative radiation to non-CNS disease and vaginal brachytherapy);

• Has received prior hormonal therapy for the treatment of endometrial carcinoma within 1 week before enrollment;

• Expect to use any active vaccine against infectious diseases (such as influenza vaccine, chickenpox vaccine, etc.) within 28 days before the first dose or during the study period;

• Patients received systemic glucocorticoid therapy or other immunosuppressive therapy (dose> 10mg / day prednisone or other effective hormones) within 14 days before the first dose;

• Active autoimmune diseases that require systemic treatment have occurred within 2 years before the first dose;

• Subjects known to be allergic to the study drug or any of its excipients or have experienced a severe allergic reaction to other monoclonal antibodies;

• Has uncontrollable symptoms of brain metastases, spinal cord compression, cancerous meningitis;

• Has any bleeding or bleeding event = CTC AE Grade 3 or unhealed wounds, ulcers or fractures within 4 weeks before enrollment;

• Patients with a clear tendency to gastrointestinal bleeding;

• Suspected or definite presence of symptoms or signs of radiation enteritis, and recurrence within 1 year from the end of radiotherapy;

• Patients whose tumors have invaded large blood vessels or poorly demarcated from the blood vessels according to imaging findings (CT/MRI);

• Prophylactic use of low dose aspirin (=100mg/d) and low molecular weight heparin (=40mg/d) is permitted in patients undergoing thrombolysis or anticoagulant therapy;

• Has clinically significant thyroid dysfunction before enrollment;

• Has multiple factors affecting oral medication (such as inability to swallow, chronic diarrhea and intestinal obstruction);

• Has any severe acute complications before enrollment:

1. Blood pressure control is not ideal (systolic pressure >= 150 mmHg, diastolic pressure >= 100 mmHg);

2. Patients had Unstable angina pectoris, myocardial infarction, =grade 2 congestive heart failure, or arrhythmia requiring treatment (including QTc =480 ms) within 6 months before enrollment;

3. Active or uncontrolled serious infection (=CTC AE grade 2 infection);

4. Epidemiological test results during the screening period showed that any of the following is met: * HBsAg positive and HBV DNA exceeds the upper limit of normal value (those who fall within the normal range after antiviral treatment can be included); * Anti-HCV positive and HCV RNA positive; * HIV positive;

5. Poorly controlled diabetes (fasting blood glucose = grade 2);

6. Had an arterio / venous thrombotic / carcinothrombotic event within 6 months, such as cerebrovascular accident (including transient ischemic attack, intracerebral hemorrhage, cerebral infarction), deep vein thrombosis, pulmonary embolism, and Hypertensive crisis or hypertensive encephalopathy;

7. Exacerbated chronic obstructive pulmonary disease (COPD) or other respiratory diseases that require hospitalization, or have active lung infections and/or acute bacterial or fungal infections that require intravenous antibiotic treatment within 28 days before the first dose.

• Has participated in other anti-tumor intervention clinical trials within 4 weeks before the first medication;

• According to the judgement of the researchers, there are other factors that may lead to the termination of the study. For example, other serious diseases including mental disorders need to be treated together, serious laboratory abnormalities, accompanied by family or social factors, which will affect the safety of the subjects, or the collection of data and samples.

Related Conditions & MeSH terms

• Gynecological Cancer

Intervention

Drug:
• Penpulimab
Penpulimab is a humanized monoclonal antibody targeting programmed cell death-1 (PD-1), which prevents PD-1 from binding to PD-L1 and PD-L2 receptors on tumor cell surface, restores T cell activity, thus enhancing immune response and has potential to treat various types of tumors.
• Anlotinib
A multi-target receptor tyrosine kinase inhibitor
