Study design
Purpose of the study
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
A computerised randomisation schedule will be made available to the pharmacy staff. The schedule will list randomisation numbers and treatment names. The pharmacist will refer to the schedule and label syringes with the randomisation number and then fill the syringes with either APL-2 or placebo as per the randomisation schedule. The name of the treatment will not be entered onto the syringe. A study nurse will administer the treatments to the study subjects. Neither the pharmacist nor the nurse administering the drug will be involved in subsequent study procedures.
Subjects who complete the study screening assessments and meet all the eligibility criteria will be assigned a randomization number according to a randomization schedule and will receive the corresponding treatment.
Subjects will be randomized to receive either APL-2 or placebo, maintaining a 1:1 ratio for the sentinels in Cohort 1 and a 3:1 for the remainder of the cohort, and 4:1 ratio in each subsequent cohort.
The planned randomization numbers are:
R1001-R1006 for Cohort 1
R2001-R2005 for Cohort 2
R3001-R3005 for Cohort 3
R4001-R4005 for Cohort 4
R5001-5005 for Cohort 5
R6001-R6005 for Cohort 6.
If a subject needs to be replaced, the replacement randomisation number will be increased by 100, e.g. R2005 will be replaced by R2105. The same treatment will be allocated to the replacement subject.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
A computerised randomisation scheme will be created by a statistician who is not otherwise involved in the study.

Statistical methods / analysis
No formal sample size estimate was performed and the sample size chosen for this study has been determined as adequate to meet the study objectives
The placebo subjects from all cohorts will be pooled into a single placebo group for all summaries and presentations.
Descriptive statistics (arithmetic mean, standard deviation [SD], sample size [N], median, minimum, and maximum) will be calculated for quantitative safety data and frequency counts will be compiled for classification of qualitative safety data.
No formal inferential statistics will be applied to safety assessments.
PK parameters for APL-2 will be computed from the individual serum concentrations-time data, using actual sample times using a non-compartmental approach. PK parameters will be summarized by cohort using descriptive statistics.
Pharmacodynamic data will be summarized using descriptive statistics.

Brief summary
APL-2 is an experimental drug being developed by Apellis Pharmaceuticals Inc for the potential use as a treatment for people with a broad range of blood disorders (including paroxysmal nocturnal hemoglobinuria (PNH)) and certain types of auto-immune diseases). PNH is caused by a small change to the individual’s genes, which results in red blood cells being broken down prematurely. People with PNH typically feel tired and often see some blood in their urine. The condition is unfortunately progressive with sufferers needing increasing medical care, with an average life expectancy of only 10 years after diagnosis. The currently available treatments are insufficient to deal with this complex disease with most patients not fully responding to the treatments. APL-2 works in a different way to the drugs that are currently approved, and has been shown in laboratory studies to prevent the breakdown of red blood cells and keep them healthy. It is hoped that APL-2 will help improve the quality of life and reduce the severity of the condition for PNH sufferers.
This study will be first study of APL-2 in humans. The assessments of the safety, tolerability, pharmacokinetics, and pharmacodynamics following administration of single doses of APL-2 will guide decisions to further develop the drug.
