Inclusion criteria

* Male and/or female participant, between 18 and 55 years of age, inclusive, at the time of signing the informed consent form (ICF). * Certified as healthy by a comprehensive clinical assessment \[detailed medical history and complete physical examination including neurological exam (at screening and D1), skin, and mucous membranes\]. * Body weight between 50.0 and 100.0 kg, inclusive, if male, and between 40.0 and 90.0 kg, inclusive, if female, body mass index between 18.0 and 30.0 kg/m2, inclusive.

Exclusion criteria

* Any history or presence of clinically relevant cardiovascular, pulmonary, gastrointestinal, dermatologic, hepatic, renal, metabolic, hematological, neurological, osteomuscular, articular, psychiatric, systemic, ocular, gynecologic (if female), or infectious disease, or signs of acute illness. * Known history of significant immunosuppression or suspected current significant immunosuppression, including history of invasive opportunistic or helminthic infections despite infection resolution or otherwise recurrent infections of abnormal frequency or prolonged duration. * Any malignancies or history of malignancies prior to baseline (except for non-melanoma skin cancer that has been excised and cured for more than 5 years prior to baseline). * History of solid organ (including corneal transplant) or stem cell transplant. * Any pre-planned major elective surgery known about at baseline visit that in the Investigator's opinion would impede participation in the study. * Frequent headaches and/or migraine, recurrent nausea and/or vomiting (for vomiting only: more than twice a month). * Blood donation, any volume, within 2 months before inclusion. * Any nicotine use within 4 weeks before study inclusion. Regular smoking more than 5 cigarettes or equivalent in nicotine per week, unable to stop smoking or using nicotine for duration of the study. * If female, pregnancy (defined as positive beta human chorionic gonadotropin \[β-HCG\] blood test), breast feeding.

Primary

MeasureTime frameDescription
PK parameter: CmaxFrom Day 1 up to End of study (approximately 24 weeks)Maximum serum concentration observed.
Pharmacokinetic (PK) profile: AUC lastFrom Day 1 up to End of study (approximately 24 weeks)Area under the serum concentration versus time curve calculated using the trapezoidal method from time zero to the real time.
Pharmacokinetic (PK) profile: AUCFrom Day 1 up to End of study (approximately 24 weeks)Area under the serum concentration versus time curve extrapolated to infinity.

Secondary

MeasureTime frameDescription
PK parameter: TmaxFrom Day 1 up to End of study (approximately 24 weeks)Time to reach Cmax.
PK parameter: t1/2zFrom Day 1 up to End of study (approximately 24 weeks)Terminal half-life associated with the terminal slope (λz) determined
PK parameter: CL/FFrom Day 1 up to End of study (approximately 24 weeks)Apparent total body clearance after a single subcutaneous administration of a drug from the serum.
PK parameter: Vz/FFrom Day 1 up to End of study (approximately 24 weeks)Apparent volume of distribution during the terminal (λz) phase.
Pharmacokinetic (PK) profile: AUCextFrom Day 1 up to End of study (approximately 24 weeks)Percentage of extrapolated part of AUC.
Percentage of participants who experienced TEAEs including ISRs, TESAEs, and/or TEAESIsUp to end of study (approximately 24 weeks)TEAEs (Treatment-Emergent Adverse Events) including ISRs (local tolerability assessment), TESAEs (Treatment-Emergent Serious Adverse Events), and/or TEAESIs (Treatment Emergent Adverse Event of Special Interest).
Percentage of participants with potentially clinically significant abnormalitiesUp to end of study (approximately 24 weeks)Clinically significant abnormalities including Clinical laboratory evaluations, Vital signs, electrocardiogram (ECG).
Visual analog scale score for pain with subcutaneous administrationDay 1VAS (visual analog scale) is used to evaluate pain at the treatment injection site. In a range between 0 to 10 where 10 is the worst pain.
