Viozan, (Sibenadet @entity5828 , @entity62343 ) is a dual D2 @entity935 receptor, @entity2162 agonist that combines bronchodilator activity with the sensory afferent modulating effects associated with D2-receptor agonism. Investigation in animal models of key @entity1030 ( @entity1030 ) symptoms has demonstrated that sibenadet effectively inhibits sensory nerve activity, thereby reducing reflex cough, mucus production and tachypnoea. The results of the early clinical evaluation of this novel agent are reported. An initial proof of concept study (Study 1) aimed to determine the clinical potential of this novel agent by assessing the effects of three doses of sibenadet therapy relative to placebo, with two commonly used bronchodilators, intended to provide a benchmark against which sibenadet activity could be judged. In all, 701 @entity1 were randomized to one of three sibenadet dose groups (400, 600 or 1000 microg ex valve), @entity3045 200 microg, @entity13265 (IB) 40 microg or placebo, all three times daily via pressurized metered dose inhaler (pMDI) for 4 weeks. Once the results of Study 1 had been evaluated, a dose-ranging, study (Study 2) involving 872 @entity1 randomized to receive sibenadet (45, 270, or 495 microg ex actuator), or placebo all three times daily via pMDI, for 6 weeks commenced. Both studies were preceded by a 2-week baseline phase and followed by a 2-week follow up period.The primary efficacy variable identified changes in key @entity1030 symptoms over the treatment period (compared with baseline data) as determined by the novel Breathlessness, Cough and Sputum Scale (BCSS). In addition, data on lung function, health-related quality of life and adverse events were collected. @entity1 receiving sibenadet therapy three times daily exhibited statistically significantly greater improvements in BCSS total score than those receiving placebo or bronchodilator therapy alone. A clear dose-response was evident in Study 2. Symptom improvement in this study was also accompanied by improved lung function and health-related quality of life. Sibenadet therapy was well tolerated with an adverse events profile comparable to current bronchodilator therapy. These data were viewed as extremely encouraging, warranting further, large-scale clinical investigation.
