Inclusion Criteria:

1. Informed consent form (ICF) understood and signed before initiating any study procedures
2. Healthy male or female, as assessed by the authorized site clinician (listed on FDA Form 1572)

6. In female subjects of childbearing potential, a negative serum pregnancy test at Screening Visit and on Day -1

   - Note: A woman is considered of childbearing potential unless post-menopausal (> / = 1 year without menses without other known or suspected cause and with a FSH level in the menopausal range), or surgically sterilized (hysterectomy, salpingectomy, oophorectomy or tubal ligation/occlusion)

7. If female, not pregnant, not breast feeding, and not planning on becoming pregnant during the trial and for 30 days after study participation

8. Females of childbearing potential and males agree to use acceptable contraception for the duration of the trial and for 30 days (females) or 90 days (males) after final study visit

   - Note: A highly effective method of birth control is defined as one with a low failure rate (i.e., less than 1 percent per year) according to the CDC criteria. These include progestin implants, intrauterine devices (IUDs), surgical (hysterectomy, salpingectomy, oophorectomy or tubal ligation/occlusion; vasectomy), or abstinence. Use of methods with higher failure rate (such as progestin injectables, combined oral hormonal contraceptives, condoms, and diaphragms) will not be acceptable when used alone, but they could be considered if used in combination with another method (e.g., a female using combined oral contraceptives if her male partner is sterile, or if she and her non-sterile male partner use a double-barrier method), after consultation with the DMID Medical Officer

9. Male subjects must agree to refrain from sperm donation for the duration of the trial and for 90 days after Final Visit
10. Laboratory tests are in the normal reference range with acceptable exceptions
11. Vital signs are within the acceptable range
12. Has adequate venous access for blood collection
13. Urine drug screen is negative for tested substances
14. Alcohol test (breathalyzer) is negative
15. Willing to abstain from alcohol consumption for 2 days before Day -1 and during the trial

Exclusion Criteria:

1) History of a chronic medical or surgical condition that would interfere with the accurate assessment of the trial's objectives or increase the subject's risk profile

  2) History of hypersensitivity or severe allergic reaction of any type to medications, bee stings, food, or environmental factors

• Note: Severe allergic reaction is defined as any of the following: anaphylaxis, urticaria, or angioedema 3) Active allergic symptoms to seasonal and animal allergens that require treatment 4) A marked baseline prolongation of ECG intervals, or HR < 45 bpm or > 100 bpm on ECG measurements

• Note: Clinically significant abnormal ECG results include: complete left or right bundle branch block; other ventricular conduction block; 2nd degree or 3rd degree atrioventricular (AV) block; sustained atrial or ventricular arrhythmia; two premature ventricular contractions in a row; pattern of ST elevation felt consistent with cardiac ischemia; evidence of a previous myocardial infarction (MI), left ventricular hypertrophy (LVH), or more than minor non-specific ST-T wave changes; or any condition deemed clinically significant by a study investigator 6) Abnormal renal function
• Note: Normal renal function is defined as normal creatinine and normal estimated glomerular filtration rate (eGFR) [i.e., > 80.0 mL/min] values according to Cockroft-Gault 7) Positive serology results for HIV, HBsAg, or HCV 8) Febrile illness with temperature > 37.6°C for < 7 days before dosing 9) Donated whole blood or blood products within 60 days before dosing, or plans to donate before Final Visit (Day 8 ± 2)
• Note: Blood products include RBCs, WBCs, platelets, and plasma 10) Known allergic reactions to any of the study drug components present in the formulation or in its processing, as listed in the IB 11) Treatment with another investigational product within 30 days of dosing or 5 half-lives or twice the duration of the biological effect of the study drug (whichever is longer)
• Note: Investigational products include a drug, vaccine, biologic, device or blood product 12) Active drug or alcohol use, abuse, or dependence within 12 months before Screening Visit that, in the opinion of the investigator, would interfere with adherence to study requirements 13) Use of any prescription medication within 30 days before dosing or planned use during the study period except as noted below and approved by the designated study clinician
• Note 1: Prohibited medications include moderate or strong CYP3A4 inducers; antibiotics; injectable or oral antidiabetic drugs; anti-lipid drugs; immunosuppressive agents; immune modulators; oral corticosteroids; anti-neoplastic agents; any vaccine (licensed or investigational) except licensed influenza vaccine during the flu season, which is allowed 7 days before or after dosing
