Intervention/exposure
Study type
Interventional
Description of the intervention or exposure
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 Safety review committee (SRC) but maximum dose to not exceed 900mg per day, administered once weekly for 4 doses (on Days 1, 8, 15 and 22).
Participants will be dosed as in-patients and adherence will be monitored by site staff.

Description of the comparator or control
Placebo - SC injections, matching in appearance to WIN027 without any active study drug.
Control group
Placebo

Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
An authorised, trained staff member from the site pharmacy will dispense the study drugs according to pre-defined drug dispensing requirements. Study drug will be dispensed according to assigned randomisation number, and Study drug vial dispensed should match the randomisation number. As the study is double-blinded, sealed participant-specific code break envelopes will be produced by the unblinded statistician(s) and will be retained at the study site in a secure, accessible location.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Participants will be randomly assigned in a 3:1 ratio (Cohort 1 & 2) or 4:1 (Cohort 3) to receive WIN027 or placebo and will be documented in the study randomisation schedule. Sequence will be generated using permuted block randomisation.
