Brief Summary:
This is a multicentre, double-blind, placebo-controlled Phase III randomized clinical trial designed to evaluate the efficacy and safety of inhaled aprotinin in adult patients with moderate or severe acute respiratory distress syndrome (ARDS). A total of 156 critically ill patients admitted to intensive care units will be randomized to receive either inhaled aprotinin or placebo in addition to standard supportive care. The primary objective is to determine whether aprotinin improves clinical outcomes based on a composite endpoint of mortality and ventilator-free days at 28 days.
Detailed Description:
This study is a nation-wide, multicentre, double-blind, placebo-controlled, Phase III randomized clinical trial designed to investigate the efficacy and safety of inhaled aprotinin in adult patients diagnosed with moderate or severe acute respiratory distress syndrome (ARDS). ARDS is a heterogeneous acute inflammatory lung syndrome characterized by diffuse alveolar damage, increased vascular permeability, alveolar and interstitial edema, and severe hypoxemic respiratory failure. Despite advances in supportive care, no specific pharmacological therapy has demonstrated proven benefit.
Aprotinin is a broad-spectrum serine protease inhibitor that targets the kallikrein-kinin system and attenuates systemic inflammatory responses, including reductions in pro-inflammatory cytokines and matrix metalloproteinases (MMPs). Experimental and clinical data suggest that MMP overexpression contributes to tissue damage, coagulation abnormalities, and impaired lung repair, representing a potential therapeutic target in ARDS. Inhaled aprotinin has been used clinically in patients with respiratory conditions, including COVID-19 and chronic pulmonary disease, with no reported adverse events via this route of administration.
In this trial, 156 ICU patients with moderate or severe ARDS will be enrolled and randomized in a 1:1 ratio to receive either inhaled aprotinin or placebo, both administered alongside standard supportive care. The aprotinina dosing regimen will be four inhaled doses of 500 KIU every six hours (total 2,000 KIU/day), selected to achieve effective local pulmonary concentrations while minimizing systemic exposure. The primary endpoint is a composite of mortality and ventilator-free days at 28 days among survivors. Secondary outcomes include ICU and hospital mortality, duration of mechanical ventilation, and other clinically relevant respiratory and functional endpoints. Detailed study procedures, dosing, and administration are described in the study protocol.
All study procedures will be conducted under a double-blind design. Patients will be prospectively followed for clinical outcomes during their ICU and hospital stay according to prespecified assessment timepoints. A Data Monitoring Committee (DMC) composed of independent clinical experts will periodically review safety and efficacy data, ensuring the protection of participants and the scientific validity of the study. The estimated study duration is four years, from September 2025 to September 2029.
