Summary

This study is designed to characterize the excretion of bempedoic acid or bempedoic acid and ezetimibe into mature breast milk of healthy lactating women and assess the exposure to the breast fed infant by estimating the daily infant dosage and the relative infant dose (RID) of bempedoic acid or bempedoic acid and ezetimibe in breast milk after 6 consecutive daily doses of bempedoic acid or bempedoic acid/ezetimibe FCDP.

Eligibility Criteria

Inclusion Criteria

  • The subject must be a lactating female who had a normal full-term pregnancy and has been actively breastfeeding or pumping for at least 4 weeks; lactation must be well established per Investigator discretion.
  • The subject must be willing to pump regularly during the study to maintain milk supply and discontinue breastfeeding for the entire 13-day Treatment and Washout Periods.
  • The subject must not be pregnant.
  • The subject must be surgically sterile or willing to use 1 acceptable method of birth control.

Exclusion Criteria

  • Has clinically significant infection (e.g., pneumonia, pyelonephritis) or chronic infection within 30 days prior to enrollment.
  • Has evidence of unstable or uncontrolled, clinically significant cardiovascular, central nervous system, pulmonary, hepatic, renal, gastrointestinal, genitourinary, hematological, coagulation, immunological, endocrine/metabolic, or other medical disorder, including serious allergy, asthma, hypoxemia, hypertension, seizures, or allergic skin rash, that, in the opinion of the Investigator, would confound the study results or compromise subject safety.
  • Has estimated glomerular filtration rate (eGFR) 5 years).
  • History within the last 2 years of drug, alcohol, amphetamine and derivatives, or cocaine abuse.
  • Current smoker.
  • Blood donation, participation in a multiple blood draw clinical study, major trauma, or surgery with or without blood loss within 30 days prior to enrollment.
  • Blood transfusion for any reason within 90 days prior to enrollment.
  • Use of any 3-hydroxy-3-methylglutaryl coenzyme A (HMG CoA) reductase inhibitor (statin) concurrently or within 30 days prior to randomization.
  • Use of cyclosporine, cholestyramine, probenecid, fibrate drugs, or medications contraindicated during lactation concurrently or within 30 days prior to randomization.
  • Concomitant use or use within 30 days prior to randomization of drugs that decrease breast milk production, such as pseudoephedrine.
  • Concomitant use or use within 30 days prior to randomization of drugs that increase breast milk production, such as domperidone.
  • Use of any experimental or investigational drugs/vaccines concurrently or within 30 days or 5 half-lives of the drug, whichever is longer, prior to screening.
