Arm Description

4 participants will be administered Dengushield at 1 mg/kg body weight as Intravenous injection.

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.

5. Study Description

Brief Summary
This Phase 1 study to evaluate the safety of a single dose of Dengushield (dengue monoclonal antibody) in healthy adults.
Detailed Description
This Phase 1 study will evaluate the safety and tolerability of a single dose of Dengushield (dengue monoclonal antibody) in healthy adults in a dose-escalating study design. In addition, pharmacokinetics will also be studied.

Interventional Study Model
Parallel Assignment
Model Description
This is a Phase 1, randomized, partially-blind (observer-blind), placebo controlled, single dose ascending study in healthy adults. For the Cohort 1 (Initial Safety Cohort), no placebo control will be used and hence, blinding is not applicable. There will be 4 dose levels. The proposed doses to be studied are; 1 mg/kg, 3 mg/kg, 12 mg/kg and 25 mg/kg. Total of 40 participants will be dosed and followed till Day 84 from dosing.
Masking
ParticipantInvestigatorOutcomes Assessor
Masking Description
For the Cohort 1 (Initial Safety Cohort), no placebo control will be used and hence, blinding is not applicable.For remaining cohorts, both participant and investigator will be unaware of treatment allocation as well as the laboratories analyzing the biochemistry and hematology parameters, pharmacokinetic and immunogenicity (ADA) samples will be blinded to treatment allocation. The drug administrator will be unblinded who will prepare and administer the study drugs. The 7 day safety data for each cohort will be reviewed by group-wise unblinding. Individual level unblinding will be done only in cases of suspected serious adverse reactions as per the judgement of investigator or medical monitor / sponsor representative.
