| NCT00311987 | Study of 3,5-Diiodothyropropionic Acid (DITPA) in Hypercholesterolemic Patients | Terminated | Johns Hopkins University | Phase 1/Phase 2 | 2006-04-01 | The natural thyroid hormones, thyroxine (T4) and triiodothyronine (T3), are known to have a cholesterol-lowering effect. Their pharmacologic use for this purpose is limited, however, by their actions on other organs, including the heart, bone, and brain, where there can be side effects of excessive thyroid hormone action. 3,5-diiodothyropropionic acid (DITPA) is a thyroid hormone analog with relative selectivity for a form of the thyroid hormone receptor expressed in the liver, where it regulates several aspects of lipid metabolism, including the clearance of low-density lipoprotein (LDL) cholesterol. This study is designed to determine whether DITPA is safe and effective in achieving LDL cholesterol levels that are consistent with the National Cholesterol Education Program Adult Treatment Panel III (NCEP ATP III) guidelines in patients who have not achieved those levels on conventional therapy, due to drug-resistant disease, drug intolerance, or both. This is a single-center, randomized, double-blind, placebo-controlled study. Following a 4-week Pre-Randomization Phase with dietary counseling and a 2-week placebo run-in, eligible patients will be randomized (1:1:1) to receive DITPA (90 mg/day, 180 mg/day), or placebo for a total treatment duration of 12 weeks. Sixty (60) patients will be randomized to 1 of 3 treatment groups in a 1:1:1 ratio (i.e., 20 patients per treatment group): - DITPA at 90 mg/day (45 mg twice a day [BID] taken orally) - DITPA at 180 mg/day (90 mg BID taken orally) - Placebo (BID taken orally) Those patients randomized to receive DITPA at 90 mg/day will receive 45 mg/day for the first 2 weeks, followed by 90 mg/day for 10 weeks. Those patients randomized to receive DITPA at 180 mg/day will receive 45 mg/day for the first 2 weeks, followed by 90 mg/day for the next 2 weeks, and then 180 mg/day for 8 weeks. |
| NCT00403390 | Generic vs. Name-Brand Levothyroxine | Completed | Boston Children’s Hospital | Phase 3 | 2006-11-01 | This study compares two different brands of thyroxine (thyroid hormone). Currently, pharmacists may be substituting generic formulations of thyroid hormone without your doctor knowing about this. Although a small difference in thyroid function is not significant in most healthy children, adolescents and adults, in infants and toddlers even a small difference in thyroid function can have important harmful consequences on brain development. The purpose of the present study is to learn whether the difference between brands of thyroid hormone that are currently being substituted is sufficient to cause a difference in thyroid function. |
| NCT00488644 | Combined Levothyroxine/Liothyronine Supplementation in Hypothyroid Patients With Brain Tumors | Terminated | M.D. Anderson Cancer Center | N/A | 2006-02-01 | Primary Objectives: 1. Assess whether combined treatment with Levothyroxine and Liothyronine improves learning and memory. 2. Explore the relationship between T3 treatment and other domains of cognitive function, quality of life, and mood. |
| NCT00647855 | Fasting Study of Levothyroxine Sodium Tablets 300 μg to Synthroid® Tablets 300 μg | Completed | Mylan Pharmaceuticals | Phase 1 | 2003-05-01 | The objective of this study was to investigate the bioequivalence of Mylan's levothyroxine sodium 300 μg tablets to Abbott's Synthroid® 300 μg tablets following a single 600 μg (2 x 300 μg) dose administered in healthy volunteers under fasting conditions. Single-dose pharmacokinetic parameters for baseline corrected total L-thyroxine and non-baseline corrected total L-triiodothyronine were calculated using noncompartmental techniques. |
