Effect of Perflubron-Induced Lung Growth on Pulmonary Vascular Remodeling in Congenital Diaphragmatic Hernia Congenital diaphragmatic hernia (CDH) involves lung hypoplasia and pulmonary hypertension (PH). Post-natal Perflubron ventilation induces lung growth. This phenomenon is called Perflubon-induced lung growth (PILG). However, it does not appear to ameliorate PH in CDH. We aim to determine
Safety and efficacy of perflubron-induced lung growth in neonates with congenital diaphragmatic hernia: Results of a prospective randomized trial. Mechanical transduction has been shown to promote fetal lung growth. We examined the safety and efficacy of perflubron-induced lung growth (PILG) in neonates with congenital diaphragmatic hernia (CDH) requiring extracorporeal membrane oxygenation (ECMO). Infants with left-sided CDH requiring ECMO were eligible. Exclusion criteria included active air leak, intracranial hemorrhage, major congenital anomalies, and oxygenation index >25 for 24hours. Perflubron was instilled endotracheally and continuous positive airway pressure was applied without ventilation. Survival to discharge was the primary outcome. Daily chest radiographs were used
Nebulized perflubron and carbon dioxide rapidly dilate constricted airways in an ovine model of allergic asthma. The low toxicity of perfluorocarbons (PFCs), their high affinity for respiratory gases and their compatibility with lung surfactant have made them useful candidates for treating respiratory diseases such as adult respiratory distress syndrome. We report results for treating acute allergic and non-allergic bronchoconstriction in sheep using S-1226 (a gas mixture containing carbon dioxide and small volumes of nebulized perflubron). The carbon dioxide, which is highly soluble in perflubron, was used to relax airway smooth muscle. Sheep previously sensitized to house dust mite (HDM) were challenged with HDM aerosols to induce early asthmatic responses. At the maximal responses
Conventional vs high-frequency ventilation for weaning from total liquid ventilation in lambs. To compare conventional gas ventilation (GV) and high-frequency oscillatory ventilation (HFOV) for weaning from total liquid ventilation (TLV). Sixteen lambs were anesthetized. After 1 h of TLV with perflubron (PFOB), they were assigned to either GV or HFOV for 2 h. Oxygen requirements, electrical
combining pharmacological and biophysical principles for a novel mode of action. It contains a potent bronchodilator gas (carbon dioxide or CO) and nebulized perflubron (a synthetic surfactant possessing mucolytic properties). It has demonstrated rapid reversal of allergen-induced bronchoconstriction in an ovine study model. This was a phase IIa proof-of-concept, placebo-controlled, randomized, double
of conventional medication to diseased airways. The solution requires a new approach that considers both biophysical and pharmacological aspects of treatments used in acute asthma. The result of testing several formulations was S-1226: carbon dioxide-enriched air delivered in nebulized perflubron, a synthetic surfactant. These agents act synergistically to rapidly reopen closed airways within seconds , double-blind, placebo-controlled, sequential, single-ascending-dose study conducted in Canada. Thirty-six subjects were distributed into three cohorts. Within each cohort, subjects were randomized to receive a single dose of S-1226 or a matching placebo administered over a 2-minute nebulization period. S-1226 was formulated with perflubron and 4 %, 8 %, or 12 % CO2. The dose of CO2 was sequentially

Bronchiolitis/Pneumonia.S-1226 contains a potent, safe and well-tolerated bronchodilator gas (extrinsic carbon dioxide or CO2) and perflubron (PFOB), a synthetic surfactant that facilitates restoration of surfactant function and mucus clearance. The inhaled S-1226 combination of gas, vapour and liquid aerosol penetrates obstructed airways, resulting in rapid bronchodilation, enhanced blood oxygenation , improved mucus clearance and reduction of work of breathingThe primary objective of this study is to evaluate the safety and tolerability of S-1226 composed of perflubron (PFOB) with ascending doses of carbon dioxide (4%, 8% and 12% CO2) in hospitalized subjects with moderate severity COVID-19 bronchiolitis/pneumonia. The secondary objective is to establish proof of concept that S-1226 is effective
