Summary

This trial compares two treatments for patients who have had their thyroid gland removed. One treatment uses Levothyroxine alone, and the other uses a combination of Levothyroxine and Liothyronine. These treatments replace essential hormones to help the body function normally. Some patients prefer the combination therapy despite mixed results.

Trial Design

2Treatment groups
Experimental Treatment
Active Control
Group I: Combination therapyExperimental Treatment2 Interventions
Liothyronine/levothyroxine (LT3/LT4) combination therapy. LT4/LT3 group will have 25 mcg of LT4 substituted with 5 mcg LT3 twice daily, to mimic the average daily T3 production form the thyroid The VCU Investigational Pharmacy will over-encapsulate LT4 plus 5 mcg LT3 in "AM" and "PM" color coded capsules. Patients will be instructed to take the AM drug first thing in the morning with water only, and to wait at least 30 minutes before taking other medications coffee or breakfast. The PM dose will be taken at least 30 minutes before dinner. Dose adjustments will be performed at the 6-week and 3-month follow up visits by an unblinded endocrinologist (Dr. Yavuz) aiming to achieve and maintain a target TSH within the normal range and within ± 0.5 mcIU/ml from the baseline (pre-surgery) TSH, Doses will be rounded to the nearest available formulation. No changes will be made in LT3.
Group II: Single therapyActive Control2 Interventions
Levothyroxine (LT4) and placebo (a look-alike inactive substance, a "sugar pill") Patients in the LT4 group will be started at a dose of 1.6 mcg/Kg (52 The VCU Investigational Pharmacy will over-encapsulate LT4 plus placebo, in "AM" and "PM" color coded capsules. Patients will be instructed to take the AM drug first thing in the morning with water only, and to wait at least 30 minutes before taking other medications coffee or breakfast. The PM dose will be taken at least 30 minutes before dinner. Dose adjustments will be performed at the 6-week and 3-month follow up visits by an unblinded endocrinologist (Dr. Yavuz) aiming to achieve and maintain a target TSH within the normal range and within ± 0.5 mcIU/ml from the baseline (pre-surgery) TSH, Doses will be rounded to the nearest available formulation.
