About this trial
Phase 1 of this study will consist of 2 parts
* Part 1 will evaluate the safety, tolerability, pharmacokinetics and immunogenicity of PRA-216 in healthy volunteers through single ascending dose administered by either intravenous (IV) or subcutaneous (SC). * Part 2 will evaluate the safety, tolerability, pharmacokinetics (PK) and immunogenicity of PRA-216 in healthy volunteers with repeat doses of multiple ascending dose administered subcutaneously.
Phase 2a of this study is a randomized, double-blind, placebo-controlled study to investigate the efficacy, safety and immunogenicity of PRA-216 in participants with mild to moderate asthma. The dose of PRA-216 for this phase was determined from Phase 1.

Trial outcomes
Primary outcomes
Phase 1: Incidence, nature, and severity of serious adverse events (SAEs) with a single dose of PRA-216 in healthy volunteers (SAD arm)
Incidence, nature, and severity of serious adverse events (SAEs)
Phase 1: Incidence, nature, and severity of serious adverse events (SAEs) of multiple doses of PRA-216 in healthy volunteers (MAD arm)
Incidence, nature, and severity of and serious adverse events (SAEs)
Phase 2a: To evaluate the effect of multiple doses of PRA-216 compared to placebo on exhaled nitric oxide (FeNO) in asthma participants
Fractional exhaled nitric oxide (FeNO) is a non-invasive biomarker of airway inflammation in asthma.
Secondary outcomes

Time to maximum concentration of drug in plasma following single or multiple doses of PRA-216
Phase 1: Pharmacokinetics of PRA-216: AUC in healthy volunteers
Area under the curve following single or multiple doses of PRA-216
Phase 1: Pharmacokinetics of PRA-216: Cmax in healthy volunteers
