Study 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 0.1 mg versus a modified release formulation of recombinant human thyroid stimulating hormone (rhTSH) dosed at 0.1 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 1:1 ratio to receive either a single administration of 0.1 mg of Thyrogen (THYR) or 0.1 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.
