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.

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. - For Cohorts 1-3, if a subject has a positive urine drug screen that the PI believes is caused by a currently prescribed medication, (except for THC), the PI may enroll the subject if they meet all inclusion criteria, and none of the exclusion criteria. - For Cohort 4, if a subject has a positive urine drug screen that the PI believes is caused by a currently prescribed medication or positive for THC, the PI may enroll the subject if they meet all other inclusion criteria and none of the exclusion criteria. 9. Breathalyzer test is negative. 10. Available for follow-up for the duration of the study. 11.

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.

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.
