A Study of LY3526318 in Healthy Participants

A Safety, Tolerability, Pharmacokinetic, and Pilot Food Effect Study of Single- and Multiple-Ascending Doses of LY3526318 in Healthy Participants

The main purpose of this study is to learn more about the safety and side effects of LY3526318 when given by mouth to healthy participants. The study will have two parts. Each participant will enroll in only one part. For each participant, Part A will last up to 28 days and Part B will last up to 51 days, including screening and follow-up.

Inclusion Criteria:

Part A Cohorts:

- Healthy male participants (including self-reported surgically sterile males) must agree to the following:

• When engaging in sex with Women of Child-Bearing Potential (WOCBP) both the male participant and his female partner must use highly effective contraception consisting of 2 forms of birth control (1 of which must be a male barrier method such as a latex or polyurethane condom) from start of dosing throughout the clinical study period, and for 90 days after the final study drug administration
• Nonsurgically sterile male participants must not donate sperm at any time from start of dosing until 90 days beyond the administration of study drug

All Part A and Part B Cohorts:

• Female participants must be nonpregnant and not lactating, or of nonchildbearing potential (either surgically sterilized [e.g. tubal occlusion, hysterectomy, bilateral salpingectomy] or physiologically incapable of becoming pregnant, or postmenopausal with amenorrhea for at least 12 consecutive months). Healthy female participants of child-bearing potential who have a fertile male sexual partner must be willing and able to practice effective contraception from admission to 30 days after the final visit. Sexually active participants must use a combination of 2 of the following methods of contraception, including at least 1 so-called 'barrier' method:

  • Hormonal contraceptive (oral, transdermal patches, vaginal or injectable)
  • Intrauterine device with or without hormones
  • Condom ('barrier' method)
  • Diaphragm or cervical cap
  • Sexual abstinence
