Overview
Brief Summary
The main purpose of this study is to assess the amount of study drug that reaches the bloodstream and the time it takes for the body to get rid of it when given to participants with renal (kidney) impairment compared to healthy participants. The study will last up to 9 days, excluding screening.

Eligibility Criteria
Inclusion Criteria
- •For all participants:
- •Body mass index (BMI) ≥ 18.0 and ≤ 40.0 kilograms per meter squared (kg/m²) and had a minimum weight of at least 50 kg at screening
- •Have normal blood pressure, pulse rate, electrocardiogram (ECG), and blood and urine laboratory test results that are acceptable for the study
- •Female of non childbearing potential: must have undergone sterilization procedures at least 6 months prior to the Screening
- •Males who are capable of fathering a child must agree to use contraception from the time of the dose administration through 6 months after the last dose
- •For renal participants:
- •Participant has stable renal disease status and function at least 1 month prior to LOXO-292 administration.
- •Participant is not currently or has not previously being on hemodialysis
- •Baseline estimated glomerular filtration rate (eGFR) based on the Modification of Diet in Renal Disease (MDRD) equation at screening as follows:
- •Severe Renal Impairment (RI): \< 30 milliliter per minute (mL/min)/1.73m²
Exclusion Criteria
- •For renal participants:
- •Has rapidly fluctuating renal function, as determined by historical measurements; or has demonstrated or suspected renal artery stenosis. Rapidly fluctuating renal function is defined as creatinine clearance or eGFR that differs by more than 20% within at least 3 months of the screening creatinine clearance or eGFR.
