FDA Grants Orphan Drug Designation for Bayer's Investigational Ciprofloxacin DPI (Dry Powder for Inhalation) for Treatment of Non-Cystic Fibrosis Bronchiectasis

WHIPPANY, N.J., April 22, 2014 /PRNewswire/ -- Bayer HealthCare today announced that the U.S. Food and Drug Administration's (FDA) Office of Orphan Products Development has granted orphan drug designation for its investigational Ciprofloxacin Dry Powder for Inhalation (Ciprofloxacin DPI) for the treatment of non-cystic fibrosis bronchiectasis (NCFB). Patients with NCFB suffer from frequent severe acute pulmonary bacterial exacerbations which lead to further inflammation, airway and lung parenchyma damage.

The Orphan Drug Designation program provides orphan status to drugs and biologics that are intended for the safe and effective treatment, diagnosis or prevention of rare diseases and disorders that affect fewer than 200,000 people in the U.S, or that affect more than 200,000 but are not expected to recover the costs of developing and marketing a treatment drug.

About Ciprofloxacin DPI
Ciprofloxacin DPI is in development by Bayer HealthCare as chronic intermittent therapy for reducing the frequency of acute exacerbations in NCFB patients with bacterial respiratory pathogens. It comprises ciprofloxacin, a fluoroquinolone antibiotic, formulated into dry powder for inhalation using Novartis' PulmoSphere™ technology and is administered with the T-326 Dry Powder inhaler.  Ciprofloxacin DPI therapy in NCFB is currently being investigated in a global Phase III clinical trial program (RESPIRE; NCT01764841).   

About Non-Cystic Fibrosis Bronchiectasis
NCFB is a chronic respiratory disease of which up to 50 to 80 percent of cases may be idiopathic.1  A vicious cycle of recurrent microbial infections and persistent inflammation leads to further damage of airway walls and predisposes the lung to new infections.2,3  Bacterial colonization of the airways, most commonly with Haemophilus influenzae and Pseudomonas aeruginosa, is found in more than 60 percent of adult patients with stable bronchiectatic disease.2  In particular, presence of Pseudomonas aeruginosa has been associated with accelerated decline in lung function.1

The Internet of Things (IoT), in all its myriad manifestations, has great potential. Much of that potential comes from the evolving data management and analytic (DMA) technologies and processes that allow us to gain insight from all of the IoT data that can be generated and gathered. This potential may never be met as those data sets are tied to specific industry verticals and single markets, with no clear way to use IoT data and sensor analytics to fulfill the hype being given the IoT today.
Ask someone to architect an Internet of Things (IoT) solution and you are guaranteed to see a reference to the cloud. This would lead you to believe that IoT requires the cloud to exist. However, there are many IoT use cases where the cloud is not feasible or desirable. In his session at @ThingsExpo, Dave McCarthy, Director of Products at Bsquare Corporation, will discuss the strategies that exist to extend intelligence directly to IoT devices and sensors, freeing them from the constraints of ...

A completely new computing platform is on the horizon. They’re called Microservers by some, ARM Servers by others, and sometimes even ARM-based Servers. No matter what you call them, Microservers will have a huge impact on the data center and on server computing in general. Although few people are familiar with Microservers today, their impact will be felt very soon. This is a new category of computing platform that is available today and is predicted to have triple-digit growth rates for some ...
The Internet of Things will challenge the status quo of how IT and development organizations operate. Or will it? Certainly the fog layer of IoT requires special insights about data ontology, security and transactional integrity. But the developmental challenges are the same: People, Process and Platform and how we integrate our thinking to solve complicated problems. In his session at 19th Cloud Expo, Craig Sproule, CEO of Metavine, will demonstrate how to move beyond today's coding paradigm ...
Fifty billion connected devices and still no winning protocols standards. HTTP, WebSockets, MQTT, and CoAP seem to be leading in the IoT protocol race at the moment but many more protocols are getting introduced on a regular basis. Each protocol has its pros and cons depending on the nature of the communications. Does there really need to be only one protocol to rule them all? Of course not. In his session at @ThingsExpo, Chris Matthieu, co-founder and CTO of Octoblu, walk you through how Oct...
