Who may be able to join
- 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:

What is being measured
The primary outcome is the main question the study is designed to answer.

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing LY3526318 in people with Healthy, run by Eli Lilly and Company at 1 site in Netherlands.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 12 inclusion and 12 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: stopped early, as of the sponsor's last update on 12 Sep 2025. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Netherlands. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Yes. Results are posted in the registry (first posted 12 Sep 2025). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Number of Participants With One or More Serious Adverse Event(s) (SAEs) Considered by the Investigator to be Related to Study Drug Administration (time frame: Baseline Up To 32 Days). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 12 Sep 2025.
