a study of camrelizumab in combination with anlotinib in subjects advanced ovarian clear cell carcinoma

Conditions: Ovarian Clear Cell Carcinoma

Summary: this study is prospective ,open-label, single-center phase ii clinical study. target population is patients with advanced (stage iii-iv) ovarian clear cell carcinoma. study objective is to evaluate effectiveness response of camrelizumab + anlotinib in subjects with advanced ovarian clear cell carcinoma camrelizumab is a humanized anti-pd1 igg4 monoclonal antibody.

in this study, eligible subjects were given a combination of carrelizumab and alozantinib at the same time, repeated every 21 days, during treatment based on imaging evaluation of the patient if disease progression, toxicity intolerance, or other reasons specified by the regimen could be terminated.

2. previous exposure to other anti-angiogenic small molecule tki drugs, such as apatinib, alotinib, sorafinil, regofinib, etc.; 3. patients with active brain metastases (for patients with stable symptoms after treatment of brain metastases, they can be selected if they remain in a stable state for at least 4 weeks); 4. immunosuppressive drugs have been used within 28 days before the first use of carirelizumab, excluding nasal and inhaled corticosteroids or systemic steroid hormones in physiological doses (i.e., prednisolone or other corticosteroids of equivalent pharmacophysiological doses not exceeding 10 mg / day); 5. received systematic systemic therapy with anti-tumor indications of chinese herbal medicine or immunomodulatory effect (including thymus peptide, interferon, interleukin, except for the control of pleural effusion topical use) within 2 weeks before the first administration; 6. suffering from serious cardiovascular diseases: myocardial ischemia or myocardial infarction above grade ii, poorly controlled arrhythmias (including qtc interval men ≥ 450 ms, women ≥ 470 ms); grade iii. to iv. cardiac insufficiency (see annex 3 according to the nyha grade of the new york cardiology society), or if the left ventricular ejection fraction (lvef) \< 50% on cardiac color ultrasound; 7. complicated by severe infection within 4 weeks before the first medication (eg, intravenous infusion of antibiotics, antifungal or antiviral drugs), or unexplained fever \> during screening / before the first administration 38.5°c； or major surgical treatment within 3 weeks prior to the first medication; 8. the presence of active autoimmune diseases or immunodeficiency, or the history of the above, including but not limited to: autoimmune hepatitis, interstitial pneumonia, uveitis, rheumatoid arthritis, inflammatory bowel disease, pituititis, vasculitis, nephritis, etc.) shall not be included. the following exceptions are those with a history of autoimmune hypothyroidism but receiving thyroid hormone replacement therapy. after treatment with an insulin dosing regimen, patients with type 1 diabetes whose blood glucose is controlled may participate in this study. 9. subjects undergo systematic treatment such as bronchodilators, asthma control is not satisfactory, can not be included (asthma in childhood has been completely resolved, adults do not need any intervention can be included). 10. human immunodeficiency virus (hiv) infection or known to have acquired immunodeficiency syndrome (aids), untreated active hepatitis b, hepatitis c (hepatitis c antibody positive, and hcv-rna is higher than the lower limit of detection of analytical methods) or co-infection with hepatitis b and c; 11. the subject has received or plans to receive a transplant of a solid organ or blood system during the study (except for corneal transplantation); 12. are currently participating in interventional clinical research or has been treated with other experimental drugs or research devices within 4 weeks prior to the first dose; adequate recovery from toxicity and/or complications caused by any intervention before the first dose (i.e., ≦ grade 1 or at baseline, excluding fatigue or hair loss); 13. have a clear history of allergies, may be potentially allergic or intolerant to the test drug and its similar biological agents; 14. those with a history of psychotropic drug abuse and who cannot be withdrawn or have mental disorders; 15. people with a history of hereditary or acquired bleeding or coagulation dysfunction (it is up to the investigator to determine whether they can be selected) 16. uncontrolled hypertension (systolic blood pressure ≥ 140 mmhg or diastolic blood pressure ≥90 mmhg, despite optimal drug therapy); 17. those who have had significant coughing up blood 2 months prior to entry into the study, or who have had a daily hemoptysis volume of half a teaspoon (2.5 ml) or more; or have had clinically significant bleeding symptoms or a clear tendency to bleed within 3 months prior to the study, such as gastrointestinal bleeding, hemorrhagic gastric ulcer, or vasculitis; or arteriovenous thrombosis events that occurred within 6 months prior to the study, such as cerebrovascular accidents (including temporary ischemic attacks, cerebral hemorrhage, cerebral infarction), deep vein thrombosis, and pulmonary embolism; 18. abnormal coagulation function (inr\>1.5 or prothrombin time (pt)\>uln+4 seconds or aptt \>1.5uln), with bleeding tendencies or being undergoing thrombolytic or anticoagulant therapy; 19. urine routine suggests that urine protein ≥++, or confirm that the amount of urine protein ≥ 1.0g in 24 hours; 20. increases the risk associated with participating in a study or trial drug and, according to the investigator's judgment, can lead to other circumstances in which the patient is unsuitable for the study to be selected.
