Inclusion Criteria:

• Participants with advanced, metastatic, recurrent or unresectable pheochromocytoma or paraganglioma. Pathology report or pathology slides (H&E) confirming histological diagnosis must be available at the time of enrollment.
• Must have measurable disease by RECIST v1.1.
• ECOG performance status 0-2, life expectancy of at least 6 months
• Adequate organ and marrow function was required (hemoglobin >= 8.0 g/dL (5.6 mmol/L); absolute neutrophil count (ANC) >= 1500/mm^3; platelet count >= 80,000/mm^3; creatinine =< 1.5 x ULN or creatinine clearance rate (CCr) ≥60ml/min, blood urea nitrogen (BUN) ≤2.5 × upper limit of normal (ULN); total bilirubin (TB) =< 1.5 X ULN; aspartate transaminase (AST) and alanine aminotransferase (ALT) <= 2.5 x ULN (if there are liver metastases, <= 5 x ULN); albumin (ALB) ≥25 g/L; urine protein/creatinine ratio =< 1 OR 24-hour urine protein < 1.5 gram)
• Blood pressure (BP) < 150 mmHg (systolic) and < 90 mmHg (diastolic); initiation or adjustment of BP medication is permitted prior to registration provided that the average of three BP readings at a visit prior to registration is < 150/90 mmHg; NOTE: all patients with secretory pheochromocytoma or paraganglioma are REQUIRED to: 1) be evaluated in consultation by a hypertension specialist with specific experience in the management of hypertension in the setting of catecholamine-secreting tumors (usually an endocrinologist, nephrologist, or a cardiologist), and in the setting of hormone-associated hypertension) receive alpha- and beta-adrenergic blockade for at least 7-14 days prior to initiation of anlotinib; the hypertension specialist of record for each patient should be committed to closely following the patient during the clinical study with evaluation by said specialist required at cycle 1 and 2 and thereafter on an as needed basis.
• Age greater or equal to 18 years old
• Participants who give a written informed consent obtained according to institutional guidelines
• Ability to complete questionnaire(s) by themselves or with assistance

Exclusion Criteria:

• Participants who have received bevacizumab, sunitinib, sorafenib, or pazopanib less than or equal to 2 weeks prior to starting study drug, or who have not recovered (grade 1) from the side effects of these therapies.
• History of allergic reactions attributed to compounds of similar chemical or biologic composition to anlotinib.
• Participants who have many influence factors toward oral medications
• Participants receiving concurrent treatment with other anti-cancer therapy chemotherapy/systemic therapy, radiotherapy, or immunotherapy =< 28 days prior to registration) given for paraganglioma or pheochromocytoma or failure to recover from toxicities. NOTE: concurrent therapy with octreotide is allowed providing that tumor progression on this therapy has been demonstrated; concurrent therapy with bisphosphonates (e.g. zoledronic acid) or denosumab is also allowed; There is no limit to the number of prior chemotherapy or biotherapy
• Participants with known untreated brain metastases are excluded. Participants having a history of brain metastasis that have been previously irradiated or resected greater than 3 months prior to enrollment and are clinically and radiographically stable will be considered for enrollment.
• Participants with another primary malignancy within 2 years prior to starting study drug, with the exception of adequately treated in-situ carcinoma of the uterine cervix, or skin cancer (such as basal cell carcinoma, squamous cell carcinoma, or non-melanomatous skin cancer)，also with the exception of other primary malignancy caused by related genetic diseases, such as VHL.
• Participants who have undergone major surgery (e.g. intra-thoracic, intra-abdominal or intra-pelvic), open biopsy or significant traumatic injury less than or equal to 4 weeks prior to starting study drug, or participants who have had minor procedures, percutaneous biopsies or placement of vascular access device 1 week prior to starting study drug, or who have not recovered from side effects of such procedure or injury
• Participants with any of the following concurrent severe and/or uncontrolled medical conditions which could compromise participation in the study (i.e. suffering from myocardial ischemia or above grade I myocardial infarction, arrhythmias and Class I heart failure; activity or failure to control severe infections; liver disease such as cirrhosis, decompensated liver disease, chronic active hepatitis; poorly controlled diabetes (FBG)>10mmol/L); urine protein≥++, etc.)
• Participants with any of the following conditions =< 6 months prior to registration: Cerebrovascular accident (CVA) or transient ischemic attack (TIA) Serious or unstable cardiac arrhythmia Admission for unstable angina or myocardial infarction Cardiac angioplasty or stenting Coronary artery bypass graft surgery Pulmonary embolism, untreated deep venous thrombosis (DVT) or DVT which has been treated with therapeutic anticoagulation =< 30 days Arterial thrombosis Symptomatic peripheral vascular disease
• Participants failed to heal wounds or fractures for Long-term
• Participants have HIV-positive or organ transplantation
• Pregnant or breastfeeding women or any subjects who refuse to use protocol required contraception
• Participants unwilling or unable to comply with the protocol
• Investigators consider that there are any conditions that may cause the participants to fail to perform study requirements.
