* Male participants must be surgically sterile or agree to use effective contraception. Male participants must also agree not to donate sperm from the signing of the informed consent to 6 months after the last scheduled dose of the study drug.
* Willing and able to understand the characteristics and purposes of the study, including possible risks involved, and willing to comply with all the study requirements and provide written informed consent for the study.
Minimum age
18 Years
Maximum age
55 Years

Can healthy volunteers participate?
Yes
Key exclusion criteria
* Surgery within 4 weeks before Screening or planned surgery during the clinical study.
* Use of prescription medications, biological products, or other medicines within 2 weeks before Study Day 1 or 5 half-lives of the product, whichever is greater. Use of over-the-counter medications or vitamins/dietary supplements within 7 days of dosing unless considered by the Investigator to not pose a risk or impact the study results.
* Clinically significant ECG abnormality.
* Positive for HIV, active hepatitis C or B, Covid-19 virus, tuberculosis.
* Bacteria, viruses, systemic fungi, parasites, or other opportunistic infections within 30 days before Study Day 1.
* History of drug abuse in the previous 12 months before Screening, or positive for urine drug Screening (Day -28 to Day -1).
* Donated blood (including component blood) or lost > 400 mL within 3 months before Screening or received a transfusion within 3 months of Screening.
* History of relevant allergies (including allergy to any murine or human-derived protein or immunoglobulin products, rubber or latex, or other allergies that in the opinion of the Investigator make inclusion in the study inappropriate).
* Average daily smoking > 10 cigarettes/day (or equivalent) within 6 months of Screening.
* Consume > 14 standard units of alcohol per week (1 standard unit is equivalent to approximately 360 mL of beer, 45 mL of spirits with 40% alcohol, or 150 mL of wine) or a positive alcohol breath test on Day -1.
* Any disease that might interfere with the safety evaluation of the investigational product.
