NCT04022447
Dupilumab is a monoclonal anti-IL-4/13Rα antibody developed for severe asthma (SA). In France, mepolizumab was commercialized in February 2018. Before this date, many SA patients had reached a therapeutic dead end, with uncontrolled disease despite maximal available treatment. Upon the request of lung specialists involved in SA, French health authorities approved an early access program (temporary Use Authorization) allowing early access to dupilumab (before EMA's decision) from September 2017 to January 2018, for SA patients demonstrating unacceptable steroids side effects and/or life-threatening exacerbations, irrespective of their T2 status.The aim of this retrospective study was to describe the characteristics of SA patients included in the early access program and to assess changes in asthma control after a 12 months treatment.
NCT02389166
Background : Patient with hypoxemic respiratory failure treated with NIV receive between NIV session oxygen therapy. Gaz exchange disorder with a decrease of the ratio between Partial Pressure of Arterial Oxygen (PaO2) and Inspired Fraction of Oxygen (FIO2) are noticed when NIV is stopped at the end of the session du to alveolar derecruitment Optiflow is a high flow oxygen delivery system used a heated humidifier and heated breathing circuit. In observational studies, Optiflow increase oxygenation of patients with hypoxemic respiratory failure. Oxygenation is better than under high-concentration mask and work of breathing is reduced. The aim of the study is to compare in acute hypoxemic respiratory failure, optiflow to oxygen therapy under high-concentration mask, on patients oxygenation between NIV sessions (measured as the difference between PaO2/FiO2 ratio at the beginning and at the end of the session), during the first two NIV sessions Study design : Prospective, randomized, controlled, multicentric, open clinical trial with two groups: * control group with conventional clinical management, oxygen therapy and sequential used of NIV * Optiflow group with high flow oxygen delivery system, conventional clinical management and sequential used of NIV for a period of 36 hours at least. Number of subjects: 100 (50 patients per group) patients admitted in intensive Care Unit for hypoxemic respiratory failure.
