|Advanced Malignant Thyroid Tumors||Drug: rAd-p53 gene Procedure: surgery Drug: p53 gene therapy Radiation: p53 gene therapy with radioactive iodine||Phase 4|
Primary objectives of this study is to determine the efficacy profiles of rAd-p53 intra-tumor injection alone, with with concurrent radioactive iodine, or combination with surgery for treatment of advanced malignant thyroid tumors(stage III or IV) including target lesion complete response rate (LCR) and overall target lesion response rate (OLR), response duration (RD), and progress-free survival (PFS).
The secondary objectives of this study is to investigate overall response rate (OPCR) and overall complete response rate (OCR), overall survival (OS), ECOG, and safety of rAd-p53 monotherapy and combined with radioactive iodine,or surgery.
|Study Type :||Interventional (Clinical Trial)|
