HM-002-1005

The purposes of this study are to:
* Evaluate the safety and tolerability of the study drug.
* Measure how much of the study drug (HM-002-1005) and its breakdown product get into the bloodstream, and how long it takes the body to get rid of them.
* Measure the amount of glucose (blood sugar) and a substance called C-peptide in the bloodstream after receiving the study drug.
Researchers will compare the study drug to a placebo (a look-alike substance that contains no drug).
Participants will:
* Stay 5 days and 4 nights or 6 days and 5 nights at the research site, and have a follow-up phone call 7 days after leaving the research site.
* Take one (1) dose of the study drug or placebo
* Have blood taken to measure the amount of study drug and its breakdown product and the levels of glucose and C-peptide
* Have safety tests such as vital sign, ECGs, and glucose measurements
