Safety, Tolerability and Pharmacokinetics of AZD1613 in Adults With Autosomal Dominant Polycystic Kidney Disease

Inclusion Criteria

• Patients with ADPKD Mayo Class (IB-IE), as per clinical diagnosis (MIC) assessed centrally. Genetic testing results will not be used for eligibility purposes
• eGFR = 45 to 90 mL/min /1.73m2
• Body weight ≥ 45 kg and body mass index within the range 18 to 35 kg/m2 (inclusive).
• Females are to be of non-childbearing potential

Exclusion Criteria

• As judged by the investigator, any evidence of cardiac, vascular, and other renal conditions which in the investigator's opinion makes it undesirable for the participant to participate in the study.
• Positive hepatitis C antibody, hepatitis B virus surface antigen, or human immunodeficiency virus test, at screening.
• History of QT prolongation associated with other medications that required discontinuation of that medication.
• Congenital long QT syndrome.
• History of ventricular arrhythmia requiring treatment. Patients with atrial fibrillation/flutter and controlled ventricular rate HR \< 100 bpm can be eligible as judged by the investigator.
• Haemoglobin below the lower limit of the normal range or any other clinically significant haematological abnormality as judged by the investigator.
• Any clinically important abnormalities in clinical chemistry, haematology, coagulation, or urinalysis results other than those specifically described as exclusion criteria herein, as judged by the investigator.
• Systolic BP > 160 mmHg or diastolic BP > 100mmHg or HR \< 50 bpm or > 100 bpm at screening. Patients taking anti-hypertensive medication should be on a stable treatment regimen of antihypertensive therapy for at least 30 days prior to the screening visit.
• Any clinically important abnormalities in rhythm, conduction, or morphology of the resting ECG and any abnormalities in the 12-lead ECG that, as considered by the investigator, may interfere with the interpretation of QTc interval changes, including abnormal ST-T-wave morphology or left ventricular hypertrophy.
• Kidney cyst interventions such as cyst aspiration or cyst fenestration within 12 weeks prior to screening and during the screening period, or such interventions planned or anticipated within the follow-up period.
