Description of intervention(s) / exposure
Treatment: Other - Dengushield 1 mg/kg (Cohort 1) intravenous
Treatment: Other - Dengushield 3 mg/kg (Cohort 2) intravenous
Treatment: Other - Placebo 3 mg/kg (Cohort 2) intravenous
Treatment: Other - Dengushield 7 mg/kg (Cohort 3) intravenous
Treatment: Other - Placebo 7 mg/kg (Cohort 3) intravenous
Treatment: Other - Dengushield 12 mg/kg (Cohort 4) intravenous
Treatment: Other - Placebo 12 mg/kg (Cohort 4) intravenous

Experimental: Cohort 1 (Initial Safety Cohort) 1 mg/kg - 4 participants will be administered Dengushield at 1 mg/kg body weight as Intravenous injection.

Experimental: Cohort 2 Experimental 3mg/kg - Initially two participants will be randomized in 1:1 ratio to Dengushield or placebo as a sentinel cohort. If there are no causally related serious safety findings, remaining 10 participants for that cohort will be randomized in 9:1 ratio to Dengushield or placebo.

Placebo comparator: Cohort 2 Placebo 3 mg/kg - Initially two participants will be randomized in 1:1 ratio to Dengushield or placebo as a sentinel cohort. If there are no causally related serious safety findings, remaining 10 participants for that cohort will be randomized in 9:1 ratio to Dengushield or placebo and enrolled.

Experimental: Cohort 3 Experimental 7 mg/kg - Initially two participants will be randomized in 1:1 ratio to Dengushield or placebo as a sentinel cohort. If there are no causally related serious safety findings, remaining 10 participants for that cohort will be randomized in 9:1 ratio to Dengushield or placebo.

Placebo comparator: Cohort 3 Placebo 7 mg/kg - Initially two participants will be randomized in 1:1 ratio to Dengushield or placebo as a sentinel cohort. If there are no causally related serious safety findings, remaining 10 participants for that cohort will be randomized in 9:1 ratio to Dengushield or placebo.

Experimental: Cohort 4 Experimental 12 mg/kg - Initially two participants will be randomized in 1:1 ratio to Dengushield or placebo as a sentinel cohort. If there are no causally related serious safety findings, remaining 10 participants for that cohort will be randomized in 9:1 ratio to Dengushield or placebo.

Placebo comparator: Cohort 4 Placebo 12 mg/kg - Initially two participants will be randomized in 1:1 ratio to Dengushield or placebo as a sentinel cohort. If there are no causally related serious safety findings, remaining 10 participants for that cohort will be randomized in 9:1 ratio to Dengushield or placebo.
