[¹⁴C]-LY4515100 Oral Solution: \[¹⁴C\]-LY4515100 administered orally

LY4515100 Tablet: LY4515100 administered orally

[¹⁴C]-LY4515100 IV: \[¹⁴C\]-LY4515100 administered IV

Study summary

The main purpose of this study is to evaluate how the body handles \[¹⁴C\]-LY4515100. The study will investigate how much \[¹⁴C\]-LY4515100 enters the bloodstream from the stomach or intestines and is available to have an effect on the body, how the body changes \[¹⁴C\]-LY4515100 so that it can be used or removed, and how the body gets rid of \[¹⁴C\]-LY4515100. For each participant, the study will last about 9 weeks and will include a Clinical Research Unit (CRU) stay lasting between 10 and 30 days.

Exclusion Criteria: * Have significant previous or current history of cardiovascular, respiratory, hepatic, renal, gastrointestinal, endocrinal, hematological, neurological, thromboembolism, or bleeding disorder capable of significantly altering the absorption, metabolism, or elimination of drugs; of constituting a risk when taking the study intervention; or of interfering with the interpretation of data. * Have a significant history of or current psychiatric disorders. * Have history of stomach or intestinal surgery or resection that would potentially alter absorption or excretion of orally administered drugs. Uncomplicated appendectomy and hernia repair will be allowed. * Have a history of constipation or have had acute constipation within 3 weeks prior to check-in. * Have had exposure to significant diagnostic, therapeutic, or employment-related radiation within 12 months prior to dosing, for example, serial x-ray or computed tomography scans, barium meal, or current employment in a job requiring radiation exposure monitoring.
