Newron Pharmaceuticals Phase Two Study Update

Milan, Italy – March 3, 2008 - Newron Pharmaceuticals S.p.A. (“Newron”, SWX: NWRN), a research and development company focused on novel CNS and pain therapies, and Hunter-Fleming Ltd., a private UK bio-pharmaceutical company developing new medicines to treat neurodegenerative and inflammatory disorders, today announced that Hunter-Fleming has received a recommendation from the independent Data Safety Monitoring Board (DSMB) to continue a Phase II safety and tolerability study with HF0220 in patients with Alzheimer’s disease (AD). The recommendation is based on the results of an interim review of the study being undertaken by Hunter-Fleming. On February 9, 2008, Newron signed an agreement to acquire 100% of the issued share capital of Hunter-Fleming.

The Phase IIa multi-centre, double blind placebo controlled, biomarker trial includes 40 patients in study centres in the UK and Sweden, who are treated for 28 days at different doses of HF0220.

An independent data monitoring committee has now completed their review of the data from the first phase of the trial. They have concluded that the data collected to date justify the initiation of a second one month treatment phase which will, in addition to safety and tolerability, assess the biological markers that may be used in future efficacy trials in AD.

Mike Capaldi, Hunter-Fleming’s CEO, commented: “We are very encouraged by the report of the data monitoring committee. The interim results confirm that HF0220 is safe and well tolerated. We look forward to gaining more information on the properties of HF0220 in patients with Alzheimer’s disease in the second part of the study.”

Luca Benatti, Newron’s CEO, added: “The results of this review support our belief in the Hunter-Fleming pipeline and in particular the potential of HF0220 to treat this major debilitating disease.”
