Key exclusion criteria
1. History of chronic or recurring dermatologic disease (other than scabies) that could interfere with the diagnosis and/or subsequent clinical assessment of scabies.
2. Diagnosis of crusted/Norwegian scabies or scabies that, in the opinion of the Investigator, would require treatment with more than one standard of care (e.g. scabies requiring concurrent topical and oral treatment).
3. Received any treatment for scabies within 7 days of Screening, including but not limited to permethrin, ivermectin, benzyl benzoate, lindane, crotamiton, malathion, and/or tea tree oil.
4. Presence of any other clinically relevant condition, including infection, immunological disorder, malignant disease, and/or other underlying condition or circumstance at Screening or Baseline that would put the subject at increased risk from participating in the study or confound study evaluations.
5. Poor venous access.
6. Received an investigational agent within 28 days of Screening (or 5 half-lives of the investigational agent, whichever is longer).
7. Body Mass Index over 35 kg/m2.
8. Clinically relevant abnormal findings in vital signs, 12-lead electrocardiogram (ECG), or physical examination at Screening and/or Baseline in the opinion of the Investigator.
9. Clinically relevant laboratory abnormalities at Screening, including:

1. alanine aminotransferase or aspartate aminotransferase > 2.5 x upper limit of reference range;
2. creatinine > 2.0 milligrams per deciliter (mg/dL);
3. hemoglobin < 9.5 g/dL (female) or <10.5 g/dL (male);
4. amylase > 2.0 x upper limit of reference range.
10. Known or suspected hypersensitivity to macrocyclic lactones or excipients used in the formulation of moxidectin.
11. Use of systemic steroids within 14 days of Screening, or history of prolonged use of systemic and/or high-dose inhaled corticosteroids, or use of topical steroids for 7 out of the 14 days prior to Screening.
12. Subjects with known or suspected Loa loa coinfection.
13. Difficulty swallowing tablets.
14. Pregnant or breastfeeding, or planning to become pregnant.
15. Known or suspected alcohol or illicit substance abuse.
