NCT07245368

Brief Summary

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.

Outcome Measures

Primary Outcomes (3)

  • 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)

    Up to Study Day 169

  • 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)

    up to Study Day 169

  • 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.

    Up to Study Day 57

Secondary Outcomes (9)

  • Phase 1: Immunogenicity of PRA-216: ADA in healthy volunteers

    Up to Study Day 169

  • Phase 1: Pharmacokinetics of PRA-216: Tmax in healthy volunteers

    Up to Study Day 169

  • Phase 1: Pharmacokinetics of PRA-216: AUC in healthy volunteers

    Up to Study Day 169

  • Phase 1: Pharmacokinetics of PRA-216: Cmax in healthy volunteers

    Up to Study Day 169

  • Phase 2a: Incidence, nature, and severity of serious adverse events (SAEs) of PRA-216 in patients with asthma

    Up to Study Day 197

  • +4 more secondary outcomes
