Researchers have designed a new study medicine called enlicitide decanoate (MK-0616) as a new way to lower the amount of low-density lipoprotein cholesterol (LDL-C) in a person's blood. Enlicitide decanoate will be called "enlicitide" from this point forward. Lithium (also called lithium carbonate) is a medicine used in bipolar disorder.

Researchers want to learn about lithium when taken at the same time with enlicitide.

They want to:

• Measure a person's blood to find out if the amount of lithium in the blood is the same when lithium is taken alone or with enlicitide
• Learn about the safety of lithium when taken alone or with enlicitide and if people tolerate it
