Brief Summary: Forty-six 46 eligible healthy subjects who provide written informed consent will be enrolled to participate in a 2 arm parallel group study to assess and compare the pharmacokinetics and safety profile of Thyrogen dosed at 01 mg versus a modified release formulation of recombinant human thyroid stimulating hormone rhTSH dosed at 01 mg Ten 10 of these subjects will have the thyroid uptake of radioiodine 123I measured at baseline and following their single dose of study medication All doses will be administered via intramuscular IM injection

Following confirmation of study eligibility subjects will be randomized in a 11 ratio to receive either a single administration of 01 mg of Thyrogen THYR or 01 mg of the modified release

Randomization will be stratified by whether or not patients will have the thyroid uptake of radioiodine 123I measured following their single dose of study medication Five 5 patients in each treatment arm will have uptake measured while 18 in each arm will not

Each subject will have blood samples taken to determine the pharmacokinetics of serum TSH at -12 hours and just prior to dosing and at various hours up to 14 days following the administration of Thyrogen or the modified release formulation In addition for the evaluation of pharmacodynamics each subject will have samples of blood taken to determine serum free T4 total T4 free T3 and total T3 at -12 hours and just prior to dosing and at various hours up to 14 days following the administration of study treatments

All subjects will undergo a 12-lead electrocardiogram ECG just prior to dose administration and 1 2 3 4 5 7 10 and 14 days following study treatment administration In addition subjects will undergo 24 hours of Holter monitoring at baseline and four 4 consecutive 24-hour Holter monitoring sessions post treatment to yield a total of 96 hours of continuous monitoring of cardiac function following treatment administration All subjects will undergo ultrasound evaluations to determine thyroid volume at baseline and 48 hours following treatment administration

Twenty-four hours following the administration of Thyrogen or the modified release formulation a subset of five 5 subjects in each treatment arm will receive a dose of 123I prepared to be 400µCi on the day of radioiodine administration based on the utilized nuclear pharmacys calibration schedule Thyroid gland uptake will be measured via a probe in these 10 subjects at 6 24 and 48 hours following radioiodine administration

Blood chemistry complete blood count CBC urinalysis and a physical exam will be conducted 14 days after treatment administration or at the time of early termination as a final safety assessment

Each subjects duration of study participation will be approximately 4 weeks
