Eligibility Criteria

Age20 Years - 45 Years
Sexmale
Healthy VolunteersYes
Age GroupsAdult (18-64)

You may qualify if:

  • The participant has a body mass index (BMI) ≥18.5 and ≤30.0 kilograms (kg)/square meter (m\^2) at the Screening Visit.
  • The participant is, in the opinion of the investigator, generally healthy based on medical history; a physical examination; vital signs; an electrocardiogram (ECG); and the results of the clinical chemistry, hematology, urinalysis, serology, and other laboratory tests.

You may not qualify if:

  • The participant has taken disallowed medication \<1 week prior to the first dose of study drug or \<5 half-lives prior to the Screening Visit for any medication taken.
  • The participant has or has had any clinically significant immunological, cardiovascular, respiratory, metabolic, renal, hepatic, gastrointestinal, endocrinological, hematological, dermatological, venereal, neurological, or psychiatric disease or other major disorder.
  • The participant has had surgery or trauma with significant blood loss \<3 months prior to the first dose of study drug.
