Study on the Treatment of Differentiated Thyroid Carcinoma With Anlotinib

Study Overview
=================
Brief Summary
-----------------
The purpose of this study is to evaluate the efficacy of anlotinib in patients with locally advanced or metastatic differentiated thyroid cancer resistant to iodine therapy.

Official Title
-----------------
An Exploratory Study on Efficacy of Anlotinib Hydrochloride in the Treatment of Locally Advanced or Metastatic Differentiated Thyroid Cancer

Conditions
-----------------
DTC - Differentiated Thyroid Cancer

Intervention / Treatment
-----------------
* Drug: Anlotinib hydrochloride


Participation Criteria

Eligibility Criteria
-----------------
Inclusion Criteria: locally advanced or metastatic RAIR-DTC (papillary, follicular [including Hürthle cell], and poorly differentiated) progressed within 18 months after the last treatment according to the Response Evaluation Criteria in Solid Tumors, version 1.1 Patients with RAIR-DTC should meet at least 1 of the following conditions: (a) the tumor invaded vital organs, cannot be completely removed nor suitable for further iodine treatment, or (b) lesions do not demonstrate iodine uptake on any radioactive iodine scan, or (c) received cumulative RAI activity ≥22.3 GBq (≥600 mCi), or (d) tumors retained iodine uptake but demonstrated radiological examination confirmed disease progression within 18 months after RAI treatment. at least one measurable lesion on computed tomography (CT) or magnetic resonance imaging (MRI) according to RECIST 1.1 Eastern Cooperative Oncology Group (ECOG) performance status (PS) 0-2 life expectancy of at least 6 months adequate main organ function ((a) Hemoglobin (HBG) ≥ 90g/L, (b) neutrophil count (ANC) ≥ 1.5×109/L, (c) platelet count (PLT) ≥ 80×109/L, (d) total bilirubin < 1.5×ULN (upper limit of normal), (e) alanine aminotransferase (ALT) and aspartate aminotransferase AST ≤ 2.5×ULN, if accompanied by liver metastases, then ALT and AST ≤ 5 × ULN; (f) serum creatinine (Cr) ≤ 1.5 × ULN or creatinine clearance rate (CCr) ≥ 60 ml/min; (g) left ventricular ejection fraction ≥ 50% of the normal level Negative pregnancy test (serum or urine) within 7 days prior to enrollment for women of childbearing potential (subjects should use appropriate contraception until 6 months after the last dose) Exclusion Criteria: Patients who have received external radiotherapy or iodine-131 therapy in recent 3 months, or plan to receive other systemic anti-tumor therapy or anti-tumor therapy with traditional Chinese medicine during the study period. Patients with other malignant tumors within 5 years or currently. Except primary cervical cancer, non-melanoma skin cancer and superficial bladder tumor. The toxicity of CTCAE (4.0) above grade 1 was not alleviated, excluding patients with neurotoxicity (≤ grade 2) and alopecia caused by oxaliplatin. With factors affecting oral administration (such as swallow, chronic diarrhea, etc.). Patients with pleural effusion or ascites causing respiratory syndrome (CTCAE2 level above). Patients who underwent major surgery, open biopsy or significant traumatic injury within 4 weeks. Regardless of the severity, patients with any physical signs or history of bleeding, patients with bleeding or bleeding events greater than or equal to CTCAE 3 within four weeks prior to the first administration, or patients with unhealed wounds, fractures, ulcers. Patients with arterial or venous thromboembolic events occurred within 6 months, such as cerebrovascular accident (including transient ischemic attack), deep vein thrombosis and pulmonary embolism.
