Criteria

Inclusion Criteria:

• Healthy, adult, males and females between the ages of 18 and 55 years, inclusive, at Screening.

• Body weight between 50-109 kg (inclusive) and body mass index (BMI) within 18.0-29.99 kg/m2 (inclusive) at Screening.

• Medically healthy with no clinically significant medical history, physical examination, laboratory profiles, vital signs or ECGs, as deemed by the PI or designee.

• Current non-smokers who have not used any nicotine-containing products (chewed or smoked) or replacement products including electronic cigarettes for at least 3 months prior to first dosing.

• Women must meet one of the following criteria: a) postmenopausal; b) surgically sterile; c) of childbearing potential and practicing contraception, as described below:

• Postmenopausal (postmenopausal women must have no menstrual bleeding for at least 1 year prior to first dosing and menopause is confirmed by FSH levels consistent with postmenopausal status), or

• Surgically sterile (e.g., hysterectomy, bilateral oophorectomy, hysteroscopic sterilization) for at least 6 months prior to first dosing, or

• Women of childbearing potential must be non-lactating and agree to either using a highly effective acceptable form of birth control (e.g., non-hormonal intrauterine device plus condom and spermicide).

• A non-vasectomized, male subject must agree to use a condom with spermicide or abstain from sexual intercourse during the study until 90 days after the last dosing. (No restrictions are required for a vasectomized male provided his vasectomy has been performed 4 months or more prior to the first dosing. A male who has been vasectomized less than 4 months prior to study first dosing must follow the same restrictions as a non-vasectomized male.)

• If male, must agree not to donate sperm from the first dosing until 90 days after the last dosing.

• Understands the study procedures in the informed consent form (ICF), and is willing and able to comply with the protocol.

Exclusion Criteria:

• Past or present diseases, which, as judged by the PI or designee, may affect the outcome of this study or pose an additional risk to the subject by their participation in the study, including, but not limited to, significant medical abnormality including: psychiatric, neurologic, pulmonary, cardiac, gastrointestinal, genitourinary, renal, metabolic, endocrinologic, or autoimmune disorder.

• Is mentally or legally incapacitated or has significant emotional problems at the time of the Screening visit or expected during the conduct of the study.

• Positive result for human immunodeficiency virus (HIV), hepatitis B surface antigen (HBsAg), or hepatitis C virus (HCV) antibody at Screening.

• Family history of QTc prolongation or of unexplainable sudden death at <50 years of age.

• History or presence of any of the following:

• sick sinus syndrome, second or third degree atrioventricular block, myocardial infarction, pulmonary congestion, symptomatic or significant cardiac arrhythmia, prolonged QTcF interval, or conduction abnormalities;

• ischemic heart disease, symptomatic arrhythmias, or poorly controlled hypertension.

• Knowledge of any kind of cardiovascular disorder/condition known to increase the possibility of QT prolongation or history of additional risk factors for torsade de pointes (e.g., heart failure, clinically significant hypokalemia, family history of Long QT Syndrome or Brugada Syndrome) or cardiac conduction disorders.

• Any condition that may interfere with the absorption, metabolism, or elimination of the study drug.

• History of, or active, alcohol or illicit drug abuse as defined by the Diagnostic and Statistical Manual of Mental Disorders, fourth edition, manual, within 2 years prior to the first dosing. Alcohol abuse is defined as an average intake of two or more drinks (12 oz beer, 1.5 oz of hard liquor, or equivalent) per day.

• Laboratory safety test results that are outside of the normal reference ranges (unless clinically acceptable to the PI or designee) at Screening.

• Resting supine HR <50 bpm or >100 bpm at Screening or check-in (Day -2). Minor deviations will be acceptable if considered to be of no clinical significance by the PI or designee.

• Resting supine systolic blood pressure <90 mmHg or >140 mmHg; resting supine diastolic blood pressure <50 mmHg or >90 mmHg at Screening or check-in.

• Significant history or presence of ECG findings at Screening or check-in (Day -2), including:

• QTcF >450 msec

• QRS >110 msec, if >110 msec, result will be confirmed by a manual over read

• PR >200 msec

• Second or third-degree atrioventricular (AV) block.

• Significant history or presence of ECG findings as judged by the PI or designee at

Screening or check-in (Day -2), including:

• ECG abnormalities which interfere with accurate QT measurement

• T wave flattening or other abnormalities which in the opinion of the PI (or designee) may interfere with the analysis of QT intervals

• Any rhythm other than sinus rhythm, which is interpreted by the PI (or designee) to be clinically significant.

• Significant safety laboratory abnormalities that would place the subject at undue risk in the PI or designee's opinion, including but not limited to serum alanine aminotransferase (ALT) or serum aspartate aminotransferase (AST) >1.2 x upper limit of normal at Screening or check-in.

• Positive urine cotinine at Screening.

• Unable to refrain from or anticipates the use of:

• Any drug, including prescription and non-prescription medications, herbal remedies, or vitamin supplements beginning 14 days or 5 half-lives (whichever is longer) prior to the first dosing or likelihood that such treatment will be needed at any time during the study (unless approved in advance by the Sponsor). Medications listed in Section 11.4.2 will be allowed.

• Participation in another clinical study within 30 days prior to the first dosing. The 30-day window will be derived from the date of the last blood collection or dosing, whichever is later, in the previous study to Day 1 of Period 1 of the current study.

• Donation of blood or blood loss >500 mL within the 56 days prior to the first dosing.

• Plasma donation within 7 days prior to the first dosing.

• Any condition or situation that, in the opinion of the PI or designee, would prevent proper evaluation of the safety, PK, and/or PD of the study drug according to the study protocol (e.g., poorly compliant subject, poor venous access, allergies to medical plastics/latex/adhesive dressing/medical tape).

• History of hypersensitivity or allergy to moxifloxacin or any study medication.

• History of tendonitis or tendon rupture with moxifloxacin or any other quinolone type drug.

• History of unexplained loss of consciousness, unexplained syncope, near drowning with hospital admission.

• Use of any marijuana product within 6 months prior to the first dosing.

• Use of illicit drugs or tetrahydrocannabinol-containing medicines within 6 months prior to the first dosing.

• Female subjects with a positive pregnancy test at Screening or check-in or lactating.

• Positive urine drug or alcohol results at Screening or check-in.

• Has tattoo(s) or scarring at or near the site of injection or any other condition which may interfere with injection site examination, in the opinion of the PI or designee.

• Subjects intending to lose weight during the study.
