A Phase 1, Single Centre, Double-blind, Randomized, Placebo-controlled Parallel-group Study to Evaluate the Pharmacokinetics, Safety, Tolerability and Immunogenicity of Tezepelumab After Single-Dose Subcutaneous Administration in Healthy Chinese Subjects (DIRECTION-CK)
A Phase 1, Single Centre, Double-blind, Randomized, Placebo-controlled Parallel-group Study to Evaluate the Pharmacokinetics, Safety, Tolerability and Immunogenicity of Tezepelumab After Single-Dose Subcutaneous Administration in Healthy Chinese Subjects (DIRECTION-CK)
This is a Phase 1, Single Centre, Double-blind, Randomized, Placebo-controlled Parallel-group Study to Evaluate the Pharmacokinetics, Safety, Tolerability and Immunogenicity of Tezepelumab after Single-Dose Subcutaneous Administration in Healthy Chinese Subjects.
This is a Phase 1, single centre, randomized, double-blind, placebo-controlled, single dose, parallel group study in healthy Chinese male or female subjects. 48 healthy subjects will be randomly assigned to one of the three treatment cohorts (i.e. 1:1:1 to Low dose, Medium dose and High dose) to receive a single dose of tezepelumab or placebo in a 3:1 ratio. Each subject will only participate in one cohort. Dose level is unblinded and treatment (tezepelumab or placebo) will be double-blinded within each treatment cohort. Following a screening period of a maximum of 28 days, subjects will stay at the study facility for two nights starting from the day before dosing (Day -1) to Day 2. Subjects will receive a single dose of tezepelumab or placebo subcutaneously on Day 1 and safety monitoring and serial collection of blood samples for PK evaluation will be followed throughout the study period. The follow up period after the dosing will be 112 days.
