Body mass index (BMI) between 18 and 32 kg/m2, inclusive, at the Screening Visit.~9. Healthy, determined by pre-study medical evaluation (medical history, physical examination, vital signs, 12-lead ECG, and clinical laboratory evaluations), as judged by the Investigator.~10. Is willing and able to comply with study restrictions and to remain at the central processing unit (CPU) for the in-patient duration of the study and return for all follow-up outpatient visits.~11. QTcF or QTcB \< 450 msec at Screening (may be repeated once).~Exclusion Criteria:~1. Is participating in another clinical study of any investigational drug, device, or intervention or has received any investigational medication during the last 30 days or five half-lives, whichever is longer, before Baseline (Day -1).~2. Subject is judged by the Investigator or the Medical Monitor to be inappropriate for the study.~3. Subject has a history or current evidence of a serious and/or unstable cardiovascular, respiratory, gastrointestinal, hematologic, autoimmune, blood dyscrasias or other medical disorder, including psychiatric disorders, cirrhosis or malignancy. History of minor skin cancers (not including melanoma) or surgically treated, limited cervical carcinomas (i.e., carcinoma in situ) are not exclusionary.~4. Subject has a history or presence of proteinuria, chronic kidney disease, disease requiring immunosuppressive therapy (including systemic steroids), or is considered to be immunosuppressed for any other reason.~5. Previous receipt of antibody or biologic therapy whether licensed or investigational (immunoglobulin products, monoclonal antibodies or antibody fragments) within 30 days prior to dosing or 5 half-lives within the dose of Investigational medicinal products (IMP), whichever is longer.~6. History of a previous severe allergic reaction with generalized urticaria; angioedema or anaphylaxis.~7. Blood pressure \>160/100 mmHg or \<90/50 mmHg (may be repeated once if abnormal), at the Screening visit and Day 1.~8.

History of pre-existing latent infections (e.g., tuberculosis) or any infection requiring hospitalization or treatment with antivirals or antibiotics, or vaccination within 30 days prior to administration of study medication.~10. Concomitant use of marketed or investigational systemic immunosuppressive or immunomodulatory medications (e.g., corticosteroids, methotrexate, azathioprine, etc. and/or biologics) is prohibited and require a washout period prior to Screening (30 days or 5 half lives, whichever is longer).~11.

Subjects with a positive urine drug (inclusive of marijuana) or alcohol Screening test result at Screening and Day -1.~17. Subjects with a positive hepatitis B surface antigen test or evidence of chronic hepatitis C virus (HCV) infection at Screening (a negative HCV antibody assay at screening is sufficient to rule-out chronic HCV infection for this study).~18. Subjects with a known history of a positive Human Immunodeficiency Virus (HIV) or a positive test result at Screening.~19. Subjects who have donated \>500 mL or blood within 60 days prior to start of Screening.~20. The subject has donated any plasma within 7 days prior to Baseline (Day -1).~21.
