  2. Any significant arrhythmia,
  3. Conduction abnormalities,
  4. Clinically significant PR(PQ) interval prolongation (> 240 ms); intermittent second or third degree atrioventricular (AV) block, or AV dissociation,
  5. Complete bundle branch block and/or QRS duration > 120 ms.
• Any positive result at Screening Visit for serum hepatitis B surface antigen or anti-hepatitis B core antibody, hepatitis C antibody, and human immunodeficiency virus antibody.
• Suspicion or known Gilbert's and/or Lesch-Nyhan syndrome
• History of hypersensitivity to drugs with a similar chemical structure or class to verinurad, allopurinol, cyclosporine or rifampicin or excipients.
• Subjects who wear soft contact lenses (due to possible staining from rifampicin), unless the subject is prepared to refrain from wearing soft lenses throughout Treatment Period 3 until after the last PK sample collection.
• Women of childbearing potential.
• Carrier of the Human leukocyte antigen B*58:01 allele.
• Has received another new chemical or biological entity (defined as a compound which has not been approved for marketing in the US or EU) within 30 days or within 5 half-lives (whichever is longer) of the first administration of verinurad in this study.
• Plasma donation within 1 month of screening or any blood donation/loss more than 500 mL during the 3 months prior to screening.
• History of severe allergy/hypersensitivity or ongoing allergy/hypersensitivity, as judged by the Investigator or history of hypersensitivity to drugs with a similar chemical structure or class to Novel uric acid transporter 1 transporter inhibitor & xanthine oxidase inhibitor.
• Current smokers or those who have smoked or used nicotine products within the 3 months prior to screening.
• Positive screen for drugs of abuse, cotinine or alcohol at Screening or on each admission to the Clinical Unit.
• Use of drugs with enzyme-inducing properties such as St John's Wort within 3 weeks prior to the first administration of verinurad.
• 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 prior to the first administration of IMP or longer if the medication has a long half-life.
