Eligibility Criteria

Age19 Years - 55 Years
Sexall
Healthy VolunteersYes
Age GroupsAdult (18-64)

You may qualify if:

  • Must be ≥ 19 and ≤ 55 years of age at Screening.
  • Must be willing and able to voluntarily give written informed consent by signing an Institutional Review Board (IRB)/Independent Ethics Committee (IEC)-approved informed consent form prior to any study-related procedures being performed.
  • Must have a body mass index ≥ 18.5 and ≤ 32 kilogram per square meter (kg/m2) and weigh ≥ 50 kg.
  • Participants of childbearing potential are eligible to participate if they are not pregnant or breastfeeding and agree to use one highly effective and one barrier method of contraception, if sexually active, for the duration of the study through 90 days after the last study drug administration. Participants must not donate eggs for the duration of study through 90 days after the last dose of study drug.
  • Participants capable of producing sperm must agree that they will use one barrier method of contraception and that their partners of childbearing potential will use one highly effective method of contraception for the duration of the study through 90 days after the last study drug administration. Participants must not donate sperm for the duration of study through 90 days after the last dose of study drug.

You may not qualify if:

  • Have a history of clinically significant hematologic, renal, neurologic, pancreatic, gastrointestinal, hepatic, cardiovascular, psychological, pulmonary, metabolic, endocrine, immunological, allergic disease, or other major disorders, as determined by the PI.
  • Have any surgical or medical condition that could possibly affect drug absorption (including inflammatory bowel disease, history of gastrectomy, cholecystectomy, or other gastrointestinal tract surgery except appendectomy).
  • Have a current significant medical or psychiatric condition, as determined by the PI.
  • Have a history of serious adverse reaction or serious hypersensitivity to any drug.
  • Have, in the opinion of the PI, evidence of clinically significant hepatic or renal impairment including alanine aminotransferase (ALT) or aspartate aminotransferase (AST) \> the upper limit of normal (ULN) or bilirubin \> 1.5 × ULN. Note: Participants with Gilbert syndrome without evidence of hepatic impairment may be enrolled.
  • Have a history or presence of an abnormal electrocardiogram (ECG), including, but not limited to, complete left bundle branch block, second- or third-degree heart block, evidence of prior myocardial infarction, or any other abnormality that is clinically significant in the PI's opinion or precludes accurate interpretation and calculations of cardiac intervals (e.g., QT, QRS).
  • Have clinically significant abnormalities, as assessed by the PI, in laboratory tests at the screening and admission visits. Note: Participants may be rescreened at the discretion of the PI with Sponsor approval.
  • Have abnormal blood pressure: supine systolic blood pressure \< 90 or \> 140 mmHg, supine diastolic blood pressure \< 50 or \> 90 mmHg, pulse rate \< 40 or \> 100 bpm, and body temperature \< 35.4 or \> 37.8 °C (\< 96 or \> 100.3 °F) at the screening and admission visits.
  • Have a prolonged corrected QT interval using Fridericia's formula (QTcF) during the 12- lead ECG at Screening or pre-dose on Day 1 \> 450 ms for participants assigned male at birth and \> 470 ms for participants assigned female at birth.
  • Have a hemoglobin level \< 12 g/dL (participants assigned male at birth) or \< 10.5 g/dL (participants assigned female at birth).
  • Have participated in any other investigational drug study within 30 days of dosing or within 7 half-lives of the investigational product, whichever is longer, or have previously participated in the current study.
  • Use any prescription medication within 7 days or 5 half-lives (whichever is longer) of the first dose administration and/or anticipated use through the follow-up visit.
  • Use any over-the-counter medication (including vitamin/mineral supplements and herbal medicines, such as St. John's wort and non-standard herbal teas) within 7 days of the first dose administration and/or anticipate using through study participation and the follow-up visit.
  • Receive a positive result in a SARS-CoV-2 test or a COVID-19 vaccine within 30 days prior to Screening.
  • Have poor peripheral venous access.
  • +12 more criteria
