Brief summary

The primary objective of the study is to estimate the PK parameters of ribupatide in participants with severe renal impairment or end-stage kidney disease (ESKD) after a single dose of ribupatide subcutaneous (SC) injection compared with participants with normal renal function.

Inclusion criteria

* Have body mass index ≥18.5 at Screening. * Female Participants: Must not be breastfeeding or planning to breastfeed during the study and for at least 35 days after the study drug dose. * Female participants: Must have a negative serum pregnancy test at Screening. * Have suitable venous access for blood sampling.

Exclusion criteria

* Have history or presence of clinically significant cardiovascular, pulmonary, hepatic, renal, hematological, gastrointestinal, endocrine, immunologic, dermatologic, psychiatric, or neurological disease/disorder, including any acute illness, within the past 3 months determined by the Investigator (or delegate) to be clinically relevant. * Have abnormal thyroid-stimulating hormone at Screening. * Have any history of malignant disease including in situ cervical or prostate cancer within the last 5 years. * Have history of or positive test results at the Screening Visit for human immunodeficiency virus (HIV), hepatitis B surface antigen, or hepatitis C virus (HCV) antibody with HCV ribonucleic acid (RNA) confirmation if positive. * Have participated in another clinical study of a study drug or investigational device within 30 days or 5 half-lives of the study drug (whichever is longer) prior to Screening. * Have received treatment with semaglutide, tirzepatide, glucagon-like peptide-1 receptor (GLP-1R) agonist, GLP-1R/glucose-dependent insulinotropic polypeptide receptor (GIPR) agonist, or glucagon receptor agonist within 3 months prior to Screening. * Have known hypersensitivity to the study drug, glucagon-like peptide-1 (GLP-1) therapies, or any of the study drug ingredients. * Have had any vaccinations within 30 days prior to Screening. * Have current infection that requires systemically absorbed antibiotic, antifungal, antiparasitic, or antiviral medication within 10 days prior to the dose of study drug.
