Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Allocation involves contacting the holder of the allocation schedule (unblinded pharmacist) who is at central administration site.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Simple randomisation using a randomisation table created by computer software (i.e. computerised sequence generation).
Masking / blinding
Blinded (masking used)
Who is / are masked / blinded?

Other design features
Participants will be assigned to different dosages or placebo depending on which cohort they are enrolled into. This study will be performed in adult healthy volunteers (up to 36 subjects in 6 cohorts). The study will commence with Cohort 1 and progression to subsequent cohorts will be subject to review of safety and tolerability data generated from the previous cohorts. In general, each cohort consists of an eligibility/screening period of up to 3 weeks, a treatment period involving administration of a single dose of ATYR1923 (study drug) or placebo and a 4-week follow-up period.
