Detailed Description

This is a Phase I, FIH, randomized, single-blind, placebo-controlled study to assess the safety, tolerability, pharmacokinetics (PK) and Pharmacodynamics (PD) of AZD4831 after single (Part 1) and multiple (Part 2) ascending doses in healthy male subjects.

Exclusion Criteria
  • History of any clinically significant disease or disorder which, in the opinion of the Investigator, may either put the subject at risk because of participation in the study, or influence the results or the subject's ability to participate in the study.
  • History or presence of gastrointestinal (GI), hepatic or renal disease, or any other condition known to interfere with absorption, distribution, metabolism, or excretion of drugs.
  • Presence of infection(s) (particularly fungal infection), as judged by the investigator.
  • History or current thyroid disease.
  • Any clinically significant illness, medical/surgical procedure, or trauma within 4 weeks of the first administration of investigational medicinal product (IMP).
  • Any clinically significant abnormalities in clinical chemistry, haematology, or urinalysis results, as judged by the investigator.
  • Any positive result on screening for serum hepatitis B surface antigen (HBsAg), anti-hepatitis B core (anti-HBc) antibodies, hepatitis C antibody and human immunodeficiency virus (HIV).
  • Abnormal vital signs
  • Any clinically significant abnormalities in rhythm, conduction or morphology of the resting ECG and any clinically significant abnormalities in the 12-lead ECG, as considered by the investigator that may interfere with the interpretation of QTc interval changes, including abnormal ST-T-wave morphology, particularly in the protocol defined primary lead or LV hypertrophy.
  • Prolonged QTcF > 450 ms or shortened QTcF < 340 ms or family history of long QT syndrome.
  • PR(PQ) interval shortening < 120 ms (PR > 110 ms but < 120 ms is acceptable if there is no evidence of ventricular pre-excitation)
  • PR (PQ) interval prolongation (> 200 ms) intermittent second (Wenckebach block while asleep is not exclusive) or third degree AV block, or AV dissociation
  • Persistent or intermittent complete bundle branch block, incomplete bundle branch block, or intraventricular conduction delay with QRS > 110 ms. Subjects with QRS > 110 ms but < 115 ms are acceptable if there is no evidence of, for example, ventricular hypertrophy or pre-excitation.
  • ECG findings suggesting a metabolic or other non-cardiac condition that may confound interpretation of serial changes (such as hypokalemia).
  • Known or suspected history of drug abuse, as judged by the investigator.
  • Current smokers or those who have smoked or used nicotine products within the previous 3 months.
  • History of alcohol abuse or excessive intake of alcohol, as judged by the investigator.
  • Positive screen for drugs of abuse, cotinine (nicotine) or alcohol at screening or admission to the unit before the first administration of IMP.
  • History of severe allergy/hypersensitivity or ongoing clinically significant allergy/hypersensitivity, as judged by the investigator or history of hypersensitivity to drugs with a similar chemical structure or class to AZD4831.
  • Excessive intake of caffeine containing drinks or food (e.g., coffee, tea, chocolate), as judged by the investigator.
  • Use of drugs with enzyme inducing properties such as St John's Wort within 3 weeks before the first administration of IMP.
  • Use of any prescribed or non-prescribed medication including antacids, analgesics (other than paracetamol/acetaminophen), herbal remedies, megadose vitamins (intake of 20 to 600 times the recommended daily dose) and minerals during the 2 weeks before the first administration of IMP or longer if the medication has a long half-life.
  • Plasma donation within 1 month of screening or any blood donation/blood loss > 500 mL during the 3 months before screening.
  • Has received another new chemical entity (defined as a compound which has not been approved for marketing) within 3 months of the first administration of IMP in this study. The period of exclusion begins 3 months after the final dose or 1 month after the last visit whichever is the longest.
  • Vulnerable subjects, e.g., kept in detention, protected adults under guardianship, trusteeship, or committed to an institution by governmental or juridical order.
  • Involvement of any Astra Zeneca, PAREXEL or study site employee or their close relatives.
  • Judgment by the investigator that the subject should not participate in the study if they have any ongoing or recent (i.e., during the screening period) minor medical complaints that may interfere with the interpretation of study data or are considered unlikely to comply with study procedures, restrictions and requirements.
  • Subjects who are vegans or have medical dietary restrictions.
  • Subjects who cannot communicate reliably with the investigator.

Exclusion from the genetic research:

  • Previous bone marrow transplant.
  • Non-leukocyte depleted whole blood transfusion within 120 days of the date of the genetic sample collection.
