CAMBRIDGE, Mass.--(BUSINESS WIRE)--Genzyme, a Sanofi company (EURONEXT: SAN and NYSE: SNY), today announced it has received European Commission approval of a product label expansion for the use of Thyrogen® (thyrotropin alfa) with a wider irradiation dose range for postoperative thyroid remnant ablation. Thyrogen is used before radioiodine treatment to avoid temporarily discontinuing thyroid replacement therapy for postoperative thyroid remnant ablation. The revised indication in remnant ablation provides physicians with the option to administer a reduced dose of radioiodine (131-I). Previously the amount of radioiodine was specified at 100 mCi, whereas physicians may now select a dose from the range of 30 to 100 mCi.
