A Study of Tersolisib (LY4064809) in Participants With Kidney Impairment Compared With Participants With Normal Kidney Function

November 4, 2026 updated by: Scorpion Therapeutics, a wholly owned subsidiary of Eli Lilly and Company

A Phase 1, Multicenter, Parallel-Design, Single-Dose, Open-Label Study to Investigate the Pharmacokinetics and Safety of Tersolisib in Participants With Renal Impairment Compared With Participants With Normal Renal Function

The main purpose of this study is to measure how much tersolisib gets into the bloodstream and how long it takes the body to eliminate it in participants with kidney impairment compared to those with normal kidney function. The safety of tersolisib will also be evaluated.

For each participant, the study will last about 7 weeks including a 14-night stay in the clinical research unit (CRU) and one follow-up telephone call.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

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.

Ages Eligible for Study

18 years to 85 years (Adult, Older Adult)

Accepts Healthy Volunteers

Yes

Genders Eligible for Study
