Recruitment & Eligibility

• Status: COMPLETED
• Sex: All
• Target Recruitment: 36

Inclusion Criteria

• The subject has a body weight of at least 45 kg and a body mass index of 18 to 32 kg/m2, inclusive.
• QTcF must be 430 msec or less for males and 450 msec or less for females. If the mean QTcF exceeds 430 msec for males or 450 msec for females, 1 additional triplicate measurement may be taken. If this triplicate measurement also gives an abnormal QTcF result, the subject should be excluded.
• Aspartate aminotransferase (AST), alanine aminotransferase (ALT) and total bilirubin (TBil) must not be above the normal range. If the Screening test result for AST, ALT, or TBil is > 1 x ULN, but < 1.5 x ULN the assessment may be repeated once during the screening period and on day -1. If the repeat assessment is above the ULN, the subject is not eligible. If the AST, ALT, or TBil test result at Screening is > 1.5 x ULN, it cannot be repeated, and the subject is not eligible.
• Female subject is of non-childbearing potential or if of childbearing potential must use highly effective birth control from Screening through 28 days after the end of the study. Females must not be breastfeeding or donate ova from Screening through 20 days after the end of the study.
• Male subject must be using highly effective contraception from Screening through 90 days after final study drug administration. Male subject must not donate sperm starting at Screening through 90 days after final study drug administration.

• The subject has participated in any interventional clinical study or has received any investigational drugs within 30 days or 5 half-lives, whichever is longer, prior to Screening.
• The subject has participated in a prior study with regadenoson.
• The subject has history of consuming more than 14 units of alcoholic beverages per week within 6 months prior to screening or has a history of alcoholism or drug/chemical/substance abuse within past 2 years prior to screening or the subject tests positive at screening or Day -1 for alcohol or drugs of abuse.
