Official title

A Clinical Study to Evaluate the Effect of MK-0616 on the Pharmacokinetics of Levothyroxine in Healthy Adult Participants

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

Levothyroxine (T4) is a man-made thyroid hormone used to treat certain thyroid conditions. After taking levothyroxine, a person's body changes it to triiodothyronine (T3). The amount of levothyroxine in a person's blood must be carefully controlled to maintain proper function. Enlicitide decanoate was designed to lower the amount of cholesterol in a person's blood. Researchers want to learn about levothyroxine when taken at the same time with enlicitide decanoate. They want to: * Measure a person's blood to find out if the amount of levothyroxine in the blood is the same when levothyroxine is taken alone or with enlicitide decanoate * Learn about the safety of levothyroxine when taken alone or with enlicitide decanoate and if people tolerate it
