Accepts Healthy Volunteers
Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms
An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes.
An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes.
Searching Both is inclusive of interventional and observational studies.
|Eligible Ages||18 Years - 70 Years|
This trial id was obtained from ClinicalTrials.gov, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries.
Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans.
Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data.
Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs.
Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.
The sponsor is the organization or person who oversees the clinical study and is responsible for analyzing the study data.

|Recurrent Atypical/Malignant Meningioma|
Vascular endothelial growth factor VEGF is related to the abnormal angiogenesis of meningioma and can also activate other growth factor pathways. Meningiomas are vascular tumors. Studies have shown that the expression of VEGF in atypical meningiomas is twice that of benign meningiomas, and VEGF in anaplastic meningiomas is 10 times that of benign meningiomas. Therefore, anti-angiogenesis therapy may be more effective for higher grade meningiomas. Previous clinical studies have confirmed that anti-angiogenic drugs such as bevacizumab, sunitinib and PTK 787 can slow down tumor growth and prolong progression-free survival for recurrent atypical/malignant meningioma. In summary, apatinib mesylate may be an effective treatment for recurrent atypical/malignant meningioma. This prospective clinical study is now planned to verify the effectiveness and safety of apatinib mesylate in the treatment of relapsed atypical/malignant meningioma.
Experimental: test group
Drug: - Apatinib Mesylate
Apatinib mesylate tablets: Orally, 500 mg, once a day, with warm water for half an hour after a meal (the time of taking the medicine every day should be the same as possible). Continue to use 28 days as a cycle, medication until disease progression (PD), intolerable toxicity occurs or the patient withdraws informed consent. However, the longest period does not exceed 24 cycles, and the treatment after 24 cycles is determined by the investigator.
