Study of Combretastatin and Paclitaxel/Carboplatin in the Treatment of Anaplastic Thyroid Cancer (FACT)

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details. Identifier: NCT00507429

Brief Summary:
The purpose of the study is to determine the safety and efficacy of combretastatin combined with paclitaxel and carboplatin in the treatment of anaplastic thyroid cancer (ATC).

Condition or disease Intervention/treatment Phase
Anaplastic Thyroid Cancer Drug: CA4P Drug: paclitaxel Drug: carboplatin Phase 2 Phase 3

Detailed Description:
Anaplastic thyroid carcinoma (ATC) is a high-grade neoplasm, characterized by an aggressive clinical course with brief survival, and refractoriness to currently available local and systemic modalities of treatment. There is no standard therapy for ATC, and no randomized comparative trials have been known to be conducted in this disease. One potential strategy is to combine the anti-tumor activity of the vascular disrupting agent combretastatin with conventional cytotoxic agents. This study will compare the overall survival of ATC patients treated with the triplet combination of combretastatin, paclitaxel, and carboplatin compared with the doublet treatment of paclitaxel and carboplatin.
