Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Treatment: Drugs - UDP-003
Other interventions - Placebo

Experimental: UDP-003 - UDP-003 will be administered to the participants randomised to this arm. UDP-003 is a formulated as a sterile solution for injection, 300 mg/mL. Volume of administration is weight dependent and target doses are 1-25 mg/kg.

Placebo comparator: Placebo - Placebo will be administered to the participants randomised to this arm. Placebo formulated as sterile solution for injection. Volume injected will match the volumes of UDP-003 for each panel and each participant.


Treatment: Drugs: UDP-003
The UDP-003 finished product is clear, colourless to yellow liquid that is intended to be a sterile solution for IV bolus push administration in sterile water at a concentration of 300 mg/mL.

Other interventions: Placebo
Placebo will be provided as a sterile clear, colourless solution formulated to match viscosity of the UDP-003 solution.
