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)
On Day 1 subjects will be assigned a unique number (randomization number) in ascending numerical order. The randomization number encodes the subject’s assignment to 1 of the study treatments, according to the randomization schedule generated prior to the study by the Statistics Department at Quintiles. Each subject will be dispensed blinded study treatment, labeled with his/her unique randomization number.
There will be limited access to the randomization code. The investigational treatment and placebo solutions will be similar in physical appearance, the unblinded site staff will conceal the treatment for administration. This process is outlined in the Pharmacy Manual. The treatment each subject will receive will not be disclosed to the Investigator, study center staff (excluding the site pharmacist and 1 unblinded Investigator), subject, or the SMC voting members.
A sealed envelope that contains the study treatment assignment for each subject will be provided to the Investigator. The sealed envelope will be retained by the Investigator (or representative) in a secured area. In case of an emergency, the Investigator has the sole responsibility for determining if unblinding of a subject’s treatment assignment is warranted. Subject safety must always be the first consideration in making such a determination. If the Investigator decides that unblinding is warranted, the Investigator should make every effort to contact the Sponsor prior to unblinding a subject’s treatment assignment unless this could delay emergency treatment of the subject. If a subject’s treatment assignment is unblinded, the Sponsor must be notified within 24 hours after breaking the blind. Once the study is complete, all envelopes (sealed and opened) must be inventoried and returned to the Sponsor.
Subjects will be randomly assigned to receive HL161BKN or placebo, except in Cohorts 1 and 2, and the sentinel subjects where all subjects will receive HL161BKN. Investigators will remain blinded (except for Cohorts 1and 2, and the sentinel subjects) to each subject’s assigned study treatment throughout the course of the study. In order to maintain this blind, an otherwise uninvolved third party (pharmacist) will be responsible for the reconstitution and dispensation of all study treatment.
In the event of a Quality Assurance audit, the auditor(s) will be allowed access to unblinded study treatment records at the study center(s) to verify that randomization/dispensing has been done accurately.

Statistical methods / analysis
Inferential statistical analysis is not planned for this study. The study is designed to identify safe, tolerated doses of HL161BKN administered as a SC dose to healthy adult subjects. The data will be used to select doses for further investigation of the safety, tolerability and efficacy of HL161BKN administered to patients.
The sample size is not based on statistical considerations but is typical for studies of this nature, and is considered adequate to characterize the distribution of the planned endpoints. Any statistical testing will be considered exploratory and descriptive.
