Heart failure drug delivery tested in healthy volunteers

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * Male or female (sex at birth). * Age 18-55 years (both inclusive) at the time of signing the informed consent. * Body mass index 18.5-29.9 kilograms per square metre (kg/m\^2) (both inclusive) and body weight less than or equal to (≤) 120 kilograms (kg) at screening (visit 1). * Considered to be generally healthy based on the medical history, physical examination, and the results of vital signs, electrocardiogram and clinical laboratory tests performed during the screening visit (visit 1), as judged by the investigator. Exclusion Criteria: * Any laboratory safety parameters at screening (visit 1) outside the below laboratory ranges, see laboratory manual for specific values. * Alanine aminotransferase (ALT) greater than (\>) upper limit of normal (ULN) +10 percentage (%) * Aspartate aminotransferase (AST) \>ULN +20% * Bilirubin \>ULN +20% * Creatinine \>ULN +10% * Estimated glomerular filtration rate (eGFR) (Chronic Kidney Disease Epidemiology Collaboration \[CKD-EPI\]) less than (\<) 90 milliliters per minute/1.73square meter (mL/min/1.73m\^2) * Urine albumin-to-creatinine ratio (UACR) greater than or equal to (≥) 30 milligrams per gram (mg/g) * Second or third degree atrioventricular-block, prolongation of the QRS complex over 120 milliseconds (ms), or of the QT interval corrected using Fridericia's formula (QTcF) interval over 450 ms, or any other clinically significant abnormal electrocardiogram results as judged by the investigator at screening (visit 1). * Supine blood pressure at screening (visit 1) outside the range of 90-139 millimeters of mercury (mmHg) for systolic or 50-89 mmHg for diastolic. * Heart rate outside the range of 50-89 beats/minute at screening (visit 1). * Presence or history (as declared by the participant or reported in the medical records) of cardiovascular disease including stable and unstable angina pectoris, myocardial infarction, transient ischaemia, stroke, heart failure, cardiac decompensation, clinically significant arrhythmia and clinically significant conduction disorders. * Known history of severe symptomatic untreated anaemia in the 90 days prior to screening (visit 1) (e.g., haemoglobin \<90 grams per litre (g/L)) * Presence or history (as declared by the participant or reported in the medical records) of acute or chronic kidney disease or injury. * Presence of thrombocytopenia, defined as thrombocyte count \<150 x 10\^9 cells/L at screening (visit 1), or history (as declared by the participant or reported in the medical records) of bleeding disorder. * Presence or history (as declared by the participant or reported in the medical records) of conditions associated with disruption of blood-brain barrier (e.g. multiple sclerosis).
