A Phase I Randomized, Single-Blind, Placebo-Controlled Study to Assess the Safety, Tolerability, Pharmacokinetics, and Pharmacodynamics of AZD4248 Following Single and Multiple Ascending Dose Administration in Healthy Participants and Participants With Chronic Kidney Disease and Type 2 Diabetes and to Assess Home Measurements of Creatinine in a Prospective, Non-interventional Cohort Study
This study will evaluate safety, tolerability, pharmacokinetics (PK), and pharmacodynamics (PD) of single ascending doses (SAD) and multiple ascending doses (MAD) of AZD4248 administered as an oral solution and intravenous (IV) infusion. Additionally, the study investigates the non-interventional feasibility of home measurement of serum creatinine in participants with diabetic kidney disease (DKD).
⁃ \- Healthy participants with suitable veins for cannulation or repeated venipuncture.
⁃ Parts A and B:
• Have a body mass index (BMI) between 18 and 30 kilograms per millimeter (kg/m2), inclusive.
• For Chinese participants (Part A2): participants are to be Chinese, defined as having both parents and 4 grandparents who are Chinese. This includes second and third generation participants of Chinese descent whose parents or grandparents are living in a country other than China.
• For Japanese participants (Part B2): participants are to be Japanese, defined as having both parents and 4 grandparents who are Japanese. This includes second and third generation participants of Japanese descent whose parents or grandparents are living in a country other than Japan.
⁃ Part C:
• Have a BMI between 20 and 35 kg/m2, inclusive.
• Have a diagnosis of diabetic kidney disease (DKD).
• Hemoglobin A1C (HbA1c) of ≤ 10.5%.
• Participants are required to be on a stable dose of angiotensin converting enzyme inhibitor (ACEi) or angiotensin receptor blocker (ARB) for at least 6 weeks prior to Visit 1 and throughout the Screening Period. In addition, participants should be on stable doses of all other medication for ≥ 6 weeks before Screening.
⁃ Part D:
• Have a BMI between 20 and 35 kg/m2, inclusive.
• Have a diagnosis of DKD as defined by a) diagnosis of type 2 diabetes (T2D) b) eGFR values and c) urine albumin to creatinine ratio (UACR) values.
• HbA1c of ≤ 10.5%.
• Participants are required to be on a stable dose of ACEi or ARB for at least 6 weeks prior to Visit 1 and throughout the Screening Period. In addition, participants should be on stable doses of all other medication for ≥ 6 weeks before Screening.
• Participants must be able and motivated to use the home creatinine device and smartphone independently by successfully performing the test without assistance from site staff.
• Participants must be able to read and understand English sufficient to participate in site visits and home testing.
