A Randomized, Double-Blind, Two-Part, Placebo-Controlled, Multicenter, Phase 2a Study to Evaluate Safety, Tolerability, and Efficacy of INNA-051 as Prophylaxis for Respiratory Tract Illness in Healthy Adults 18 to 45 Years of Age Who Are at Risk for Viral Respiratory Infections
ENA Respiratory Pty Ltd
Summary
Acute upper and lower respiratory infections are a major public health problem and a leading cause of morbidity and mortality worldwide. The purpose of this trial is to assess the safety of the investigational agent INNA-051, given intranasally, and its potential effectiveness in reducing the occurrence, severity, and/or the duration of illness resulting from respiratory virus infections. The trial will enroll generally healthy adults (age 18 - 45 years) who are at risk for exposure to viral respiratory infection, for example, due to living conditions or occupation. Participants will be treated with INNA-051 or placebo once weekly for 4 weeks (Part A) or 12 weeks (Part B) during the respiratory virus season.
Description
Viral respiratory infections are associated with significant morbidity and mortality. The diversity of viruses, along with their propensity for mutation, ignited an interest in host-directed therapies that are effective across a wide range of viral pathogens. Toll-like receptors (TLRs) are potential targets for the development of such agents given their central role in host immune defenses. INNA-051, a TLR2/6 agonist, is being developed as an intranasal innate immune-boosting prophylactic approach for individuals at risk for symptoms and/or complications resulting from respiratory viral infec…
