Share: SAN FRANCISCO, Jan. 19, 2021 (GLOBE NEWSWIRE) -- InCarda Therapeutics, Inc. ("InCarda"), a privately-held biopharmaceutical company developing first-of-their-kind inhaled therapies for cardiovascular diseases, today announced dosing of the first U.S. patient in the company's multinational INSTANT Phase 2 clinical trial of InRhythm ™ (flecainide for inhalation) in patients with recent-onset paroxysmal atrial fibrillation (PAF). The trial is currently being conducted at centers in the U.S. and Europe to evaluate the optimal dose (120 mg) of InRhythm that was selected based on the positive results from the open-label, dose-ranging stage of the INSTANT study. The results from the dose-ranging stage of the trial were recently presented at the American Heart Association's (AHA) Scientific Sessions 2020. InCarda Therapeutics in collaboration with clinical investigators reported that oral inhaled flecainide can safely and rapidly convert recent-onset PAF to normal sinus rhythm (NSR). These data provided the first proof of concept for inhaled flecainide as a potentially safe and effective therapeutic option for rapidly converting PAF to NSR.
