Safety and Tolerability of the Chymase Inhibitor Fulacimstat in Patients With Left Ventricular Dysfunction After Myocardial Infarction-Results of the CHIARA MIA 1 Trial.

The chymase inhibitor fulacimstat is developed as a first-in-class treatment option for the inhibition of adverse cardiac remodeling in patients with left ventricular dysfunction (LVD) after acute myocardial infarction (MI). The aim of the study was to examine the safety and tolerability of fulacimstat in patients with LVD after remote MI. A multicenter, multinational randomized, placebo-controlled study was performed in clinically stable patients (40-79 years of age, left ventricular ejection fraction ≤ 45% because of MI in medical history) who were on stable evidence-based standard-of-care therapies for LVD post-MI including an angiotensin converting enzyme inhibitor or angiotensin receptor blocker at doses of at least half the recommended target dose.

Demonstration of the analgesic efficacy and dose-response of acetylsalicylic acid with pseudoephedrine.

To determine acute analgesia by acetylsalicylic acid (ASA) when combined with pseudoephedrine (PSE) in patients with upper respiratory tract infection (URTI), we used the sore throat pain model to measure single-dose effects of ASA 500 mg/PSE 30 mg, ASA 1000 mg/PSE 60 mg, and acetaminophen (APAP) 1000 mg/PSE 60 mg (serving as a positive control). Under double-blind, randomized, placebo-controlled conditions, 640 adult patients with confirmed acute pharyngitis and rhinosinusitis associated with URTI rated throat pain intensity and relief at intervals over 6 hours. Efficacy was demonstrated for both doses of ASA/PSE compared with placebo for all end points, including total pain relief and summed pain intensity differences, beginning at 20 minutes on both scales (all P < .

Randomized, double-blind, crossover study to investigate the effect of rivaroxaban on QT-interval prolongation.

Background: Rivaroxaban (BAY 59-7939) is a novel, oral, direct Factor Xa inhibitor in advanced clinical development for the prevention and treatment of thromboembolic disorders. Unwanted pro-arrhythmic effects are a common reason for drugs failing to gain regulatory approval; these properties can be detected by assessing the effect of the drug on the QT interval.

Objective: This study was performed, in accordance with International Conference on Harmonisation (ICH) E14 guidance, to assess whether rivaroxaban prolongs the QT interval.
