简要总结
The purpose of this trial is to investigate the safety and efficacy of LY2623091 in males and females with chronic kidney disease.
详细描述
This trial consists of 4 treatment arms: 3 LY2623091 dose levels and eplerenone. Each participant will participate in 2 treatment periods, with a minimum wash-out period of 28 days between dosing in the 2 treatment periods. Dosing days will be numbered 1-21 in each of the 2 treatment periods. Participants will receive different treatments in periods 1 and 2. Participants will be housed as inpatients during the days of the controlled diet administration and the oral potassium challenge and until at least 24 hours after its completion (Days -3 to 1; Days 19 to 22, in each treatment period). Otherwise the study will be done on an outpatient basis, with participants returning to the clinic for evaluations during each treatment period (Days 3 or 4, 7, and 14).

- •While receiving stable doses of any other applicable BP medication (including diuretic therapy) for ≥3 weeks prior to screening
- •Have seated cuff systolic BP less than or equal to (≤) 160 millimeters of mercury (mm Hg) and diastolic BP ≤100 mm Hg
- •Have serum potassium (K+)≤5.0 milliequivalents/liter (mEq/L) at Screening, and no more that 1 hospitalization due to hyperkalemia within 1 year
- •Are reliable and willing to make themselves available for the duration of the study and are willing to follow specific study procedures
- •Have venous access sufficient to allow blood sampling
- •Have lab values and other safety parameters that are, in the opinion of the investigator, acceptable for participation in the study
排除标准
- •Participants who are currently enrolled in, or have discontinued within the last 30 days of the investigational drug from, a clinical trial involving an investigational drug or device or an off-label use of an approved drug (other than the study drug used in this study), or are concurrently enrolled in any other type of medical research judged not to be scientifically or medically compatible with this study. Participants may be enrolled in this study and dosed on day 31 or greater following the last day of previous investigational drug administration
- •Have previously completed or withdrawn from this study or any other study investigating LY2623091
- •Participants who are taking any diuretic drug and not receiving a stable dose for 3 weeks prior to the screening/qualification visit and through end of treatment
- •Participants receiving a renin inhibitor, or an mineralocorticoid receptor (MR) antagonist must have a wash-out period of at least 1 month prior to randomization
- •Participants in whom dialysis or renal transplantation is anticipated by their physician within 6 months after the Screening
- •Participants with a history of acute kidney injury within 3 months before Screening
- •Participants who have or are expected to require systemic immunosuppression therapy within 30 days of Screening(except for inhalant steroids)
- •Use of oral or parenteral corticosteroids within 30 days of the Screening
- •Participants with a diagnosis of Class three (III) or four (IV) congestive heart failure (CHF) [as defined by the New York Heart Association (NYHA)]
- •Participants with evidence of human immunodeficiency virus (HIV) and/or positive human HIV antibodies; participants with a history of cirrhosis or hepatitis C or are positive for hepatitis C antibody at Screening; participants who are known to be hepatitis B surface antigen-positive or are positive for hepatitis B surface antigen at Screening
