Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Subjects in Cohort 1 were randomly assigned to treatment with APL-2 360 mg (4 subjects) or matching placebo (1 subject) by subcutaneous injection (SC) once daily for 28 days. Subjects in Cohort 2 were randomly assigned to treatment with APL-2 1,300 mg (4 subjects) or matching placebo (1 subject) SC twice weekly for 28 days. Subjects in Cohort 3 were randomly assigned to treatment with APL-2 2,600 mg (4 subjects) or matching placebo (2 subjects) SC once per week for 28 days. All subjects in Cohort 4 were assigned treatment with APL-2 1080 mg (16 subjects) SC twice weekly for 28 days. All subjects in Cohort 5 were assigned treatment with APL-2 1080 mg (8 subjects) SC twice weekly for 28 days. The Subjects will participate in one cohort only. Cohort1 and Cohort 2 were conducted in parallel. Cohort 3 was enrolled after completion of Cohort 1 and Cohort 2; Cohort 4 was enrolled after completion of Cohort 3, and Cohort 5 was enrolled after completion of Cohort 4.
Doses were administered by healthcare professionals at the study site.
Subjects attended a Screening visit (Day -28 to Day -14), resided in the clinic for 35 days from Day -1 (the day before the first dose) until Day 35, and returned to the clinic for 3 follow-up visits on Day 42, 56, and 70, and for a final exit visit on Day 84.

Primary outcome [1] 302651 0
The pharmacokinetics of daily, twice a week and once a week regimens of SC APL-2 in healthy volunteers. Noncompartmental PK parameters of AUC0-24, Cmax, Cmin, and Cav will be calculated from serum concentrations of APL-2 for Day 1 and/or for Day 22 to 29.
Timepoint [1] 302651 0
Throughout the study, blood samples will be collected for pharmacokinetic (PK) testing, including a blood sample before dosing and at 1, 2, 4, 8, and 12 hours post-dosing on Day 1, and then once per day on Day 2, 3, 4, 5, 6, 8, 15, 22, 23, 24, 25, 26, 27, 28, 29, 35, 42, 56, 79, and 84.
Primary outcome [2] 302669 0
The safety and tolerability of daily, twice a week and once a week regimens of SC APL-2 in healthy volunteers.
Timepoint [2] 302669 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, and on Day 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 42, 56, 79, and 84. ECGs will be recorded at screening, and on Day 1, 8, 15, 22, 25, 29, 35, 42, 56, 79, and 84. Blood samples will be collected for safety testing at screening, at check-in on the day before dosing, and on Day 7, 14, 21, 28, 35, 56, and 84. Urine samples will be collected for safety testing at screening, at check-in on the day before dosing, and on Day 7, 14, 21, 28, 35, and 84.
Secondary outcome [1] 336663 0
The pharmacodynamics (PD) of daily, twice a week and once a week regimens of SC APL-2 in healthy volunteers. PD assessments include the serum complement activation markers CH50, AP50, C3, and C3a.
Timepoint [1] 336663 0
Throughout the study, blood samples will be collected to measure serum complement activation markers (CH50, AP50, C3, and C3a), including blood samples at screening and on Day1, 8, 15, 22, 25, 29, 35, 42, 56, 79, and 84.

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 Clinical Trial Pharmacist. The Pharmacist will fill dosing syringes with either APL-2 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 the clinical trial team except for the Pharmacists.
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 ‘Rprnn’, where p denotes the cohort number (i.e. for Cohort 1, p=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 to the subject with the corresponding Randomisation Number and the injections will be administered by blinded study 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.

Other design features
There will be up to 5 cohorts with a total of 40 subjects. Cohort 1 and Cohort 2 were enrolled in parallel and each included 4 subjects randomised to receive APL-2 and 1 subject randomised to receive placebo. Cohort 3 was enrolled after completion of Cohort 1 and Cohort 2 and included 2 Sentinel subjects with 1 randomised to receive APL-2 and 1 randomised to receive placebo, followed by 4 more subjects one week later, with 3 randomised to received APL-2 and 1 randomised to receive placebo. Cohort 4 was enrolled after completion of treatment by Cohort 3 and was comprised of 16 subjects receiving APL-2. Cohort 5 was enrolled after completion of treatment by Cohort 4 and was comprised of 8 subjects who received APL-2.
Subjects will participate in one cohort only.
Phase
Phase 1
Type of endpoint/s
Pharmacokinetics / pharmacodynamics
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).
PK parameters for APL-2 will be computed from the individual serum concentrations-time data, using actual sample times and a non-compartmental approach.
