Outcomes
Primary outcome [1] 325376 0
Pharmacokinetic (PK) profile of a single subcutaneous (SC) dose of VIS649 including Cmax, AUC0-inf, and AUC0-last as determined through measurement of circulating serum VIS649 levels.
Timepoint [1] 325376 0
PK samples will be collected at 4 and 8 hours after receiving a single dose and then on days 2, 3, 5, 7, 9, 14, 28, 42, 56, 70, 84, 112 (End of study visit) post-dose.
Primary outcome [2] 325377 0
Characterize the safety and tolerability of VIS649 administered as a single SC dose as assessed by physical examination; recording vital signs (blood pressure, pulse, respiratory rate and oral temperature); clinical laboratory tests (serum chemistry, hematology and urinalysis); assessment of injection site pain from the Visual Analog Scale; and adverse events self-reported by the participant.
Timepoint [2] 325377 0
16 weeks post VIS649 administration
Secondary outcome [1] 387713 0
Pharmacokinetic (PK) profile of a single subcutaneous (SC) dose of VIS649 as determined through measurement of circulating serum VIS649 levels. The parameters measured will be:
Clast (time of last serum concentration),
tmax (time of maximum serum concentration),
tlast (time of last quantifiable observed concentration)
t1/2 (apparent terminal elimination half-life),
AUC0-28d (area under the concentration-time curve from day 0 to day 28),
AUC0-112d (area under the concentration-time curve from day 0 to day 112),
%AUCex (Percentage of AUC0-inf obtained by extrapolation);
Vd/F (apparent volume of distribution),
CL/F (apparent clearance).
Timepoint [1] 387713 0
PK samples will be collected at 4 and 8 hours after receiving a single dose and then on days 2, 3, 5, 7, 9, 14, 28, 42, 56, 70, 84, 112 (End of study visit) post-dose.

Summary
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.

Data sharing statement
Will individual participant data (IPD) for this trial be available (including data dictionaries)?
No
No/undecided IPD sharing reason/comment
With a single site and limited participants data sharing is not recommended for reasons of patient confidentiality. Also as a small PK study for a specific drug applicability of data is limited.
