A Study of Selpercatinib (LY3527723) in Healthy Participants

May 2, 2025 updated by: Eli Lilly and Company

A Phase I, Single-Ascending Dose Study to Evaluate the Safety, Tolerability, and Pharmacokinetics of LOXO-292 in Healthy Adult Subjects

The main purpose of this study is to determine how safe and how well tolerated selpercatinib is when given as oral doses to healthy participants. The study will also assess how fast selpercatinib gets into the blood stream and how long it takes the body to remove it. The study will last up to about 6 weeks, inclusive of screening period.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
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 Day 8
Data presented are the number of participants who experienced SAEs considered by the investigator to be related to study drug administration. A summary of SAEs and all other non-serious Adverse Event(s) (AEs), regardless of causality, is located in the Reported Adverse Event module.
Baseline up to Day 8

Secondary Outcome Measures
