A Phase 1 Relative Bioavailability Study of UCB0022 Tablets in Healthy Participants

An Open-Label, Single-Center, Randomized, 2-Way Crossover Study to Evaluate the Relative Bioavailability and Safety of Two UCB0022 Tablet Formulations in Healthy Participants

The purpose of this study is to estimate the relative bioavailability of UCB0022 Formulation 2 (Test) versus Formulation 1 (Reference) in healthy participants following single oral administration.

Inclusion Criteria:

• Participant must be minimum 18 years and maximum 55 years of age inclusive at the time of signing the informed consent form (ICF).

• Participants who are overtly healthy as determined by medical evaluation including medical history, physical examination, laboratory tests, and cardiac monitoring.

• Participants have a blood pressure (BP) and heart rate (HR) during the Screening Period or before the first dose of study intervention, as determined by triplicate BP/HR measurements in a supine position, of mean systolic BP ranging between 90mmHg and 130mmHg, mean diastolic BP ranging between 50mmHg and 80mmHg, and mean HR between 45bpm and 90bpm.

• Body weight greater than or equal (≥)45 kilograms (kg) and body mass index within the range 18.0 kilograms per meter square (kg/m2) to 30.0 kg/m2 (inclusive).

• A male participant must agree to use contraception during both Periods and for at least 14 days after the final dose of study intervention, and refrain from donating sperm during this period.

• A female participant is eligible to participate if she is not pregnant, not breastfeeding, and at least 1 of the following conditions applies:

  • Not a woman of childbearing potential (WOCBP) OR
  • A WOCBP who agrees to follow the contraceptive guidance during both Periods and for at least 14 days after the final dose of study intervention.

• Capable of giving signed informed consent, which includes compliance with the requirements and restrictions listed in the ICF and in the protocol.

Exclusion Criteria:

• Participants have any medical or psychiatric condition that, in the opinion of the investigator, could jeopardize or would compromise the study participant's ability to participate in this study.
• History or presence of cardiovascular, respiratory, hepatic, renal, gastrointestinal, endocrinological, hematological, cerebrovascular, neurological, or other major disorders capable of significantly altering the absorption, metabolism, or elimination of drugs.
• History of hypertension, hypertensive crisis, hypertensive encephalopathy, or orthostatic hypotension
• History of ischemic stroke, transient ischemic attack, angina, myocardial infarction, any systemic embolism, any clinically significant arrythmia, or congestive heart failure.
• Participants have the following liver enzyme test results during the Screening Period or Day -1:

alanine aminotransferase (ALT), aspartate aminotransferase (AST), bilirubin, or alkaline phosphatase (ALP) >1.0×upper limit of normal (ULN) (isolated bilirubin <1.5×ULN is acceptable if fractionated and direct bilirubin <35%).

• Current or chronic history of liver disease or known hepatic or biliary abnormalities (with the exception of asymptomatic gallstones).
• Participants have 12-lead electrocardiogram (ECG) with changes considered to be clinically significant (eg, QTcF >450ms in males and >470ms in females , left bundle branch block, evidence of myocardial ischemia, or second-degree Type II atrioventricular block).
• Participants have a history of risk factors for torsades de pointes.
• Participants have had any malignancy within the past 5 years except for basal cell or squamous epithelial carcinomas of the skin that have been resected with no evidence of metastatic disease for 3 years.
• Participants have had breast cancer within the past 10 years.
• Participants have a history of severe allergic reaction that required medical intervention.
• Participants have a positive HBsAg, hepatitis C virus antibody, or human immunodeficiency virus 1 and 2 antibody result at the Screening Visit.
