Description of intervention(s) / exposure
Treatment: Drugs - Cohort A
Treatment: Drugs - Placebo A
Treatment: Drugs - Cohort B
Treatment: Drugs - Placebo B

Experimental: Cohort A - Subcutaneously administer a single dose of XW003, ranging from 0.03mg to 1.0mg, every cohort by the body weight.

Placebo comparator: Placebo A - Subcutaneously administer a single dose of volume-matching placebo, ranging from 0.03mg to 1.0mg, every cohort by the body weight.

Experimental: Cohort B - Subcutaneously administer multiple SC doses of XW003, ranging from 0.2mg to 0.6mg, once weekly for 6 weeks.

Placebo comparator: Placebo B - Subcutaneously administer multiple SC doses of volume-matching placebo, ranging from 0.2mg to 0.6mg, once weekly for 6 weeks.


Treatment: Drugs: Cohort A
Participants in each cohort (A1 to A6) will be randomised to receive a SC dose of XW003 on Day 1 after overnight fasting by body weight range:

1. Proposed XW003 Dose Levels (50 kg-75 kg): 0.03mg, 0.1mg, 0.2mg, 0.4mg, 0.8mg and 0.6mg respectively for Cohorts A1 to A6.
2. Proposed XW003 Dose Levels (76 kg-90 kg): 0.03mg, 0.1mg, 0.25mg, 0.5mg, 1.0 mg and 0.6mg.

These doses are subject to change following SRC review of each cohort - XW003 dose level will not exceed 2.0 mg.

Treatment: Drugs: Placebo A
Participants in each cohort (A1 to A6) will be randomised to receive a SC dose of volume-matching placebo on Day 1 after overnight fasting by body weight range:

1. Proposed Placebo Dose Levels (50 kg-75 kg): 0.03mg, 0.1mg, 0.2mg, 0.4mg, 0.8mg, and 0.6mg respectively for Cohorts A1 to A6.
2. Proposed Placebo Dose Levels (76 kg-90 kg): 0.03mg, 0.1mg, 0.25mg, 0.5mg, 1.0 mg and 0.6mg.

These doses are subject to change following SRC review of each cohort - dose level will not exceed 2.0 mg.

Treatment: Drugs: Cohort B
Participants in cohorts B1 to B3 (n=10 per cohort) will receive multiple SC doses of XW003 (n=8) once weekly for 6 weeks following an overnight fast of at least 10 hours.

1. Subject to change following SRC review of each cohort.
2. Following 4 weeks of once weekly dosing, the SRC will review the safety data (and PK data for Cohort B1 only) to determine the treatment for the following cohort and whether dosing can commence in parallel.
3. At least 3 days prior to Cohort B3 Week 3 (i.e., 3 days prior to the third dose in Cohort B3), the SRC will review the safety and PK data for Cohorts B1 and B2 to determine whether Cohort 3 dosing for Weeks 3 to 6 may commence.

Treatment: Drugs: Placebo B
Participants in cohorts B1 to B3 (n=10 per cohort) will receive multiple SC doses of matching placebo (n=2) once weekly for 6 weeks following an overnight fast of at least 10 hours.

1. Subject to change following SRC review of each cohort.
2. Following 4 weeks of once weekly dosing, the SRC will review the safety data (and PK data for Cohort B1 only) to determine the treatment for the following cohort and whether dosing can commence in parallel.
3. At least 3 days prior to Cohort B3 Week 3 (i.e., 3 days prior to the third dose in Cohort B3), the SRC will review the safety and PK data for Cohorts B1 and B2 to determine whether Cohort 3 dosing for Weeks 3 to 6 may commence.
