Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

1. Informed consent understood and signed prior to screening procedures.
2. Assessed by the Investigator to be a healthy male or healthy, non-pregnant, non-lactating female between the ages of 18 and 65 inclusive on the day of dosing.
3. Able and willing to comply and be available for all protocol procedures and follow-up for the duration of the study.
4. Body Mass Index (BMI) of ≥18.5 and ≤35 kg/m2.
5. Females of child-bearing potential must have a negative serum pregnancy test at screening and negative urine pregnancy test on Day 1 prior to dosing.

\- A woman is considered of childbearing potential unless post-menopausal (≥ 1 year without menses) or surgically sterilized via bilateral oophorectomy, or hysterectomy or bilateral tubal ligation.
6. If the subject is female and of childbearing potential, she agrees to practice abstinence from sexual intercourse with men or use medically effective contraception (methods with a failure rate of \< 1% per year when used consistently and correctly) during participation in the study. Acceptable methods include:

* Hormonal contraception including implants, injections or oral
* Two barrier methods, e.g., condom and cervical cap (with spermicide) or diaphragm (with spermicide)
* Intrauterine device (IUD) or intrauterine system
7. Screening clinical laboratory results within normal ranges or are no greater than a Grade 1 and deemed not clinically significant by Medical Monitor (MM) and Principal Investigator (PI). Any subjects with results that are Grade 2 or above according to Appendix B will be excluded.

\- Laboratory values that are outside the range of eligibility but are thought to be due to an acute condition or due to laboratory error may be repeated once.
8. The urine drug screen is negative.

9. Breathalyzer test is negative.
10. Available for follow-up for the duration of the study.
11. Agrees not to participate in vigorous activity 2 days prior to dosing and 2 days post-dose Day 1 and Day 45 for Cohorts 1-3 and Day 1 for Cohort 4, per Investigator discretion.

Exclusion Criteria

1. History of a chronic medical condition that would either interfere with the accurate assessment of the objectives of the study or increase the risk profile of the subject.

\- Chronic medical conditions include but are not limited to diabetes; Asthma requiring use of medication in the year before screening; Autoimmune disorder such as lupus, Wegener's, rheumatoid arthritis, thyroid disease; coronary artery disease; chronic hypertension; History of malignancy except low-grade (squamous and basal cell) skin cancer thought to be cured; chronic renal, hepatic, pulmonary, or endocrine disease (except previous asthma which has required no treatment for the past year).
2. Known history of severe allergic reaction of any type to medications, bee stings, food, or environmental factors or hypersensitivity or reaction to immunoglobulins.

\- Severe allergic reactions are defined as any of the following: anaphylaxis, urticaria, or angioedema.
3. Known allergic reactions to any of the study product components present in the formulation or in the processing.
4. A marked baseline prolongation of QT/QTc interval (e.g., repeated demonstration of a QTc interval \>450 milliseconds).
5. Clinically significant abnormal electrocardiogram (ECG) at screening.

\- Clinically significant abnormal ECG results include but are not limited to: complete left or right bundle branch block; other ventricular conduction block except for incomplete RBB; 2nd degree or 3rd degree atrioventricular (AV) block; sustained ventricular arrhythmia; sustained atrial arrhythmia; two Premature Ventricular Contractions in a row; pattern of ST elevation felt consistent with cardiac ischemia; or any condition deemed clinically significant by a study investigator.
6. Positive serology results for human immunodeficiency virus (HIV), hepatitis B surface antigen (HBsAg), or hepatitis C virus (HCV) antibodies.
7. Febrile illness with temperature ≥38°C within 7 days of dosing. Subjects with acute febrile illness within 7 days of dosing may be rescreened no earlier than 7 days following resolution of symptoms.
8. Female subjects that are pregnant or breastfeeding or intending to become pregnant within the projected duration of the trial starting from the Screening visit until last dose.
9. Donation of blood or blood product within 56 days of enrollment.
10. Is currently participating or has participated in a study with an investigational product (IP) within 28 days preceding Day 1 (documented receipt of placebo in a previous trial would be permissible for trial eligibility)
11. Plans to enroll in another clinical trial that could interfere with safety assessment of the IP at any time during the study period.

\- Includes trials that have a study intervention such as a drug, biologic, or device only
12. Treatment with a mAB within 3 months of Day 1.
13. Receipt of antibody (e.g., tetanus immune globulin \[TIG\], varicella zoster immune globulin \[VZIG\], intravenous immunoglobulin \[IVIG\], IM gamma globulin) or blood transfusion within 6 months or within 5 half-lives of the specific product given.
14. Reported active drug or alcohol or substance abuse/independence or illicit drug use that, in the opinion of the Investigator, would interfere with adherence to study requirements.
15. Use of H1 antihistamines or beta-blockers within 5 days of dosing Day 1 and Day 45 for Cohorts 1-3 and Day 1 for Cohort 4 (PRN use could be allowed with MM approval).
16. Use of any prohibited medication within 28 days prior to study entry or planned use during the study period.

\- Note: Prohibited medications include immunosuppressives (except nonsteroidal anti-inflammatory drugs \[NSAIDs\]); immune modulators; oral corticosteroids (topical/intranasal steroids are acceptable); anti-neoplastic agents.
17. Previous exposure to botulinum toxin, receipt of antibodies against botulinum toxin, or previous treatment with equine antitoxin.
18. Any previous injection or any planned injection within 4 months after enrollment of botulinum toxin for cosmetic reasons, spastic dysphonia, torticollis, or any other reason.
19. Any illness or condition that in the judgment of the Investigator may affect the safety of the subject or the evaluation of any study endpoint.
20. Is a study site employee, staff, or close relative as defined.
