Primary Outcome Measures
NameTimeMethod
The safety and tolerability of single subcutaneous doses of APL-9 when administered to healthy adults.[Throughout the study, routine clinical tests will be conducted, including vital signs, ECGs, and blood and urine tests.<br>Vital signs and ECGs will be recorded at screening, upon check-in to the clinic on the day before dosing, before dosing; at 1 and 4 hours post-dosing on Day 1, and then once per day on Day 2, 3, 4, 5, 6, 7, 8, 15, 22, 29, and 43.<br>Blood and urine samples will be collected for testing at screening, upon check-in to the clinic on the day before dosing. then on Day 2, 4, 8, 15, 29, and 43.<br>]
Secondary Outcome Measures
NameTimeMethod
Serum pharmacokinetics of single subcutaneous doses of APL-9 when administered to healthy adults. AUC, Cmax, tmax, Kel and t1/2 will be determined.[Blood will be collected for serum APL-9 measurements before dosing; at 15 and 30 minutes and 1, 4, 8 and 12 hours post-dosing on Day 1, and then once per day on Day 2, 3, 4, 5, 6, 7, 8, 15, 22, 29, and 43.];Serum pharmacodynamics of single subcutaneous doses of APL-9 when administered to healthy adults, AH50, CH50, C3 and C3a will be measured.[Blood will be collected for serum complement activation marker measurements before dosing; at 1, 4 and 12 hours post-dosing on Day 1, and then once per day on Day 2, 3, 4, 5, 6, 7, 8, 15, 22, 29, and 43.]
