Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Subjects will be randomly assigned to treatment with either a single intravenous (IV) infusion of APL-9 or a single IV infusion of placebo. Doses will be administered by healthcare professionals at the study site and are expected to take approximately 30 min for subjects in the first 4 cohorts; 12 hours for subjects in the 5th cohort, and 24 hours for subjects in the 6th cohort.
This study will be conducted in 5 sequential cohorts.
The first cohort received 30 mg of APL-9 (4 subjects) or placebo (2 subjects).
The second cohort received 90 mg of APL-9 (4 subjects) or placebo (2 subjects).
The third cohort received 270 mg of APL-9 (4 subjects) or placebo (2 subjects).
The fourth cohort received 540 mg of APL-9 (4 subjects) or placebo (2 subjects).
The fifth cohort received 540 mg of APL-9 (4 subjects) or placebo (2 subjects).
The sixth cohort received 600 mg of APL-9 (4 subjects) or placebo (1 subject).

Outcomes
Primary outcome [1] 303294 0
The safety and tolerability of single intraveneous doses of APL-9 when administered to healthy adults.
Timepoint [1] 303294 0
Throughout the study, routine clinical tests will be conducted, including vital signs, ECGs, and blood and urine tests.
Vital signs will be recorded at screening, upon check-in to the clinic on the day before dosing; during dosing on Day 1; at 1, 2, 4, 8 and 12 hours after dosing on Day 1, and then once per day on Day 2, 3, 4, 5, 6, 7, 8, 11, 15, 29, and 43. ECGs will be recorded at screening, upon check-in to the clinic on the day before dosing on Day 1; before dosing; at 1, 2, 4, 8 and 12 hours after dosing on Day 1, and then once per day on Day 2, 3, 4, 5, 6, 7, 8, 11, 15, 29, and 43.
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.
Secondary outcome [1] 338546 0
Serum pharmacokinetics of single subcutaneous doses of APL-9 when administered to healthy adults. AUC, Cmax, tmax, CL/F, VZ/F and t1/2 will be determined.
Timepoint [1] 338546 0
Blood will be collected for serum APL-9 measurements before dosing; at 15 and 30 minutes and 1, 1.5, 2, 3, 4, 8 and 12 hours post-dosing on Day 1, and then once per day on Day 2, 3, 4, 5, 6, 7, 8, 11 and 15.
Secondary outcome [2] 338547 0
Serum pharmacodynamics of single subcutaneous doses of APL-9 when administered to healthy adults, AH50, CH50, C3 and C3a will be measured.
Timepoint [2] 338547 0
Blood will be collected for serum complement activation marker measurements at screening; before dosing; at 1, 2, 4, 8 and 12 hours after dosing on Day 1, and then once per day on Day 2, 3, 4, 5, 6, 7, 8, 11, 15, 18, 22,25, 29, and 43.

Study design
Purpose of the study
Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
A statistician will prepare a Randomization Schedule and send a copy to the study pharmacist. The pharmacist will fill dosing syringes with either APL-9 or placebo, and will label the syringes in a blinded fashion in accordance with the Randomization Schedule (i.e. the label for each syringe will include the Randomization Number but will not include the identity of the treatment). The Randomization Schedule will not be made available to clinic personnel.
Subjects who complete the screening assessments and meet all of the eligibility criteria will be enrolled into the study and will be assigned a unique Randomisation Number.
Randomisation Numbers will be comprised of the letter R followed by a four-digit number of the format ‘Rcrnn’, where c denotes the cohort number (i.e. for Cohort 1, c=1), r is a replacement indicator and nn is a sequential randomisation number, i.e. R1001, R1002, etc. If a subject is replaced, the digit represented by r will be sequentially increased by one, e.g. R2003 would be replaced by R2103. The replacement subject will be administered the same treatment allocated to the original participant, as indicated by the last two digits of the randomisation number (i.e. 03 for participant R2003 and R2103).
Dosing syringes will be dispensed for the subject with the corresponding Randomisation Number and the injections will be administered by blinded clinic personnel or by personnel who will not be involved in the study assessments.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
A computerised randomisation schedule will be created by a statistician who is not otherwise involved in the study.

Safety
Statistical methods / analysis
Given the exploratory nature of the study no formal statistical hypothesis testing will be performed. As no formal hypothesis testing will be conducted, the study sample sizes were not based on statistical power calculations.
Data will be presented by cohort/dose (including placebo where applicable), study day and nominal time post-dose (if appropriate). Subjects receiving placebo will be pooled across dosing cohorts for summaries. All data will be listed by cohort and dose (including placebo where applicable).
For continuous variables, the number of available observations (n), mean, standard deviation (SD), median, minimum, and maximum will be provided. For categorical variables, the frequency and percentage in each category will be displayed. Unless otherwise specified percentages of subjects will be based on the number of subjects randomized (Safety Analysis Set).
