Vernalis PLC: Promising Results of Ph Ib/II POC Study in ADHD

WINNERSH, UNITED KINGDOM -- (Marketwired) -- 04/24/14 --

Promising Results of Phase Ib/II Proof-of-Concept Study in Attention Deficit Hyperactivity Disorder (ADHD) with V81444

Vernalis plc today announces the results from a Phase Ib/II proof-of-concept (POC) study of V81444, an A2A antagonist which has potential applications for the treatment of Parkinson's disease, attention deficit hyperactivity disorder (ADHD) and other disorders of the central nervous system (CNS).

The randomised, double-blind, placebo controlled, two-period cross-over study was designed to evaluate the safety, tolerability and pharmacokinetics of V81444 dosed twice daily for 14 days and was conducted in adult patients with a confirmed diagnosis of ADHD. The study enrolled 31 patients (safety population) and, in addition to evaluating safety, tolerability and pharmacokinetics, measured the efficacy of V81444 using the ADHD Rating Scale (primary measure), PERMP-P and Clinical Global Impression (CGI) assessments (secondary measures). The efficacy assessments were conducted using the Adult Workplace Environment (AWE) model.

V81444 achieved a statistically significant improvement in the number of correct scores in PERMP-P measure (p=0.019) compared to placebo. Although not statistically significant, V81444 also showed improvements in both the ADHD Rating Scale and CGI. There were no drug-related serious adverse events and no other new or significant safety findings. The full study results will be published at a future conference.

Ian Garland, CEO of Vernalis commented "The goal of this study was to increase our understanding of V81444's safety, tolerability and pharmacokinetics and to explore its commercial potential outside of the core Parkinson's disease indication. We are pleased with the promising efficacy results, particularly achieving a statistically significant improvement in the PERMP-P measure of efficacy in just 29 patients (ITT population), which for the first time indicate potential utility of an A2A antagonist in a non-Parkinson's CNS disorder. These study results significantly enhance V81444's data package and our goal is now to partner this programme".

DevOps has often been described in terms of CAMS: Culture, Automation, Measuring, Sharing. While we’ve seen a lot of focus on the “A” and even on the “M”, there are very few examples of why the “C" is equally important in the DevOps equation. In her session at @DevOps Summit, Lori MacVittie, of F5 Networks, will explore HTTP/1 and HTTP/2 along with Microservices to illustrate why a collaborative culture between Dev, Ops, and the Network is critical to ensuring success.
In his session at @ThingsExpo, Tony Shan, Chief Architect at CTS, will explore the synergy of Big Data and IoT. First he will take a closer look at the Internet of Things and Big Data individually, in terms of what, which, why, where, when, who, how and how much. Then he will explore the relationship between IoT and Big Data. Specifically, he will drill down to how the 4Vs aspects intersect with IoT: Volume, Variety, Velocity and Value. In turn, Tony will analyze how the key components of IoT ...
When it comes to IoT in the enterprise, namely the commercial building and hospitality markets, a benefit not getting the attention it deserves is energy efficiency, and IoT’s direct impact on a cleaner, greener environment when installed in smart buildings.

There didn't exist a 'top down' approach that can manage and monitor the way a Smart Buildi...

DevOps delivers remarkable results. But does it help all of IT? Can traditional ‘mode 1’ IT benefit as much as innovative ‘mode 2’? How about the rest of your business? Or have you just shifted your bottleneck? And if so, what can you do about it? Improving dev and ops is necessary, but not sufficient. It often just shifts the burden sideways (e.g., to PMs, SQA, InfoSec, DBAs, NOC, etc.), upstream (to the PMO, Controller, Business Liaison, etc.), or downstream (to TechPubs, Service Desk, Traini...

Mobile messaging has been a popular communication channel for more than 20 years. Finnish engineer Matti Makkonen invented the idea for SMS (Short Message Service) in 1984, making his vision a reality on December 3, 1992 by sending the first message ("Happy Christmas") from a PC to a cell phone. Since then, the technology has evolved immensely, from both a technology standpoint, and in our everyday uses for it. Originally used for person-to-person (P2P) communication, i.e., Sally sends a text...

Organizations already struggle with the simple collection of data resulting from the proliferation of IoT, lacking the right infrastructure to manage it. They can't only rely on the cloud to collect and utilize this data because many applications still require dedicated infrastructure for security, redundancy, performance, etc. In his session at 17th Cloud Expo, Emil Sayegh, CEO of Codero Hosting, will discuss how in order to resolve the inherent issues, companies need to combine dedicated a...
You have your devices and your data, but what about the rest of your Internet of Things story? Two popular classes of technologies that nicely handle the Big Data analytics for Internet of Things are Apache Hadoop and NoSQL. Hadoop is designed for parallelizing analytical work across many servers and is ideal for the massive data volumes you create with IoT devices. NoSQL databases such as Apache HBase are ideal for storing and retrieving IoT data as “time series data.”
Clearly the way forward is to move to cloud be it bare metal, VMs or containers. One aspect of the current public clouds that is slowing this cloud migration is cloud lock-in. Every cloud vendor is trying to make it very difficult to move out once a customer has chosen their cloud. In his session at 17th Cloud Expo, Naveen Nimmu, CEO of Clouber, Inc., will advocate that making the inter-cloud migration as simple as changing airlines would help the entire industry to quickly adopt the cloud wit...
