Brief summary

This is a Phase 1, multicenter, randomized, double-blind, placebo-controlled, sequential single-ascending-dose (SAD) followed by multiple-dose (MD) trial in healthy adult participants aged between 18 and 65 years old. Participants will be enrolled into 1 of 3 cohorts – each cohort testing a different dose of the study drug WIN027. Participants will be dosed as in-patients at the study site and then will be followed up with multiple follow-up visits over a period of 36 weeks. The study drug WIN027 is being developed for the treatment of moderate-to-severe uncontrolled asthma and chronic obstructive pulmonary disease.

Interventions

The study drug WIN027 is given as a subcutaneous (SC) injection either as a single dose or once weekly for 4 doses. The study has 3 sequential cohorts, with participants receiving either WIN027 or placebo. Cohort 1: 450 mg (single dose on Day 1). Cohort 2: (single dose on Day 1) specific dose to be determined after review of Cohort 1 by the Safety review committee (SRC) but maximum dose to not exceed 900mg per day. Cohort 3: specific dose to be determined after review of Cohort 2 by the Safet
