This is a phase I study of LY3031207 in healthy subjects. The purposes of this study are to look at safety, how well the study drug is tolerated, and how much of the study drug gets into the blood stream and how long it takes the body to get rid of it when given to humans. Information about any side effects that may occur will also be collected. Subjects will participate in the study for approximately 3 months. This study is for research purposes only and is not intended to treat any medical condition.

Inclusion Criteria:

• Male subjects agree to use a reliable method of birth control during the study and for 3 months following the last dose of the investigational product
• Women not of child-bearing potential due to surgical sterilization (at least 6 weeks after surgical bilateral oophorectomy with or without hysterectomy or at least 6 weeks after tubal ligation) confirmed by medical history or menopause
• Menopausal women include women with either spontaneous amenorrhea for at least 12 months, not induced by a medical condition such as anorexia nervosa and not taking medications during the amenorrhea that induced the amenorrhea (eg., oral contraceptives, hormones, gonadotropin-releasing hormone, antiestrogens, selective estrogen receptor modulators, or chemotherapy) or spontaneous amenorrhea for 6 to 12 months and a follicle-stimulating hormone level greater than 40 mIU/mL

• Normotensive defined as supine systolic blood pressure (BP) <140 mmHg, and diastolic BP <90 mmHg, without the use of any antihypertensives, or results that are judged to be not clinically significant by the Investigator. Blood pressure may be retested up to 2 additional times, under well rested conditions
• Clinical laboratory test results within normal reference range for the population or investigator site, or results with acceptable deviations that are judged to be not clinically significant by the investigator

Exclusion Criteria:

• Are currently enrolled in, have completed or discontinued within the last 30 days from, a clinical trial involving an investigational product or unapproved use of a drug with a short half-life, or within 5 half-life of an investigational product with a half-life longer than 5 days, or concurrently enrolled in any other type of medical research judged not to be scientifically or medically compatible with this study

Electrocardiogram may be repeated after 5 minutes resting quietly, if the subject's heart rate is >75 beats per minute
