Brief summary

This is a Phase 1, Open-label study performed to determine the pharmacokinetics (PK), safety and tolerability and pharmacodynamics (PD) of the study drug, VIS649 solution when administered subcutaneously in healthy non-Japanese and Japanese males and females aged between 18 and 55 years. The assessment will be done in up to 3 dose cohorts. The results will facilitate the treatment of immunoglobulin (Ig) A nephropathy. The study comprises of a screening period up to 30 days before dosing, an in-house stay for approximately 3 days (in which dosing will be done on first day and discharge on second day), followed by a post-administration period of 16 weeks with follow-up visits. The total duration of the clinical study per participant will be up to approximately 20 weeks (5 months), including the screening period. A total of 36 participants (12 in each cohort) will be enrolled with 9 Non-Japanese and 3 Japanese in each cohort. A Safety Monitoring Committee will be used for reviewing safety and tolerability data of the study.

Interventions

Participants will receive a single dose of VIS649 administered via subcutaneous injection by the investigator. Group 1 will receive 200 mg VIS649, Group 2 will receive 400 mg VIS649, Group 3 will receive 400 mg VIS649 and Group 4 will receive 600 mg VIS649.
