Novexel Starts Phase II Clinical Trial With NXL103 in Adults With Acute Bacterial Skin and Skin Structure Infection...(nti-MRSA antibacterials when they wishto...),Health

NXL103, as a member of the Streptogramin class of antibiotics, has a unique mode of action, with its two components acting synergistically to inhibit the bacterial ribosome. Its spectrum of activity indicates its potential to be effective in the treatment of ABSSSI, including those caused by resistant pathogens such as MRSA.

In late 2008, Novexel announced positive results from a Phase II clinical trial evaluating NXL103 in the treatment of community acquired pneumonia (CAP).

Iain Buchanan, Novexel's CEO, said, "The start of this Phase II trial with NXL103 is another important step in the growth of the company. There is a clear need for products that can be used to manage the release of patients from hospital by allowing them to be switched from intravenous to oral therapy."

Notes to Editors

About NXL 103

NXL103 is a novel oral antibiotic made up of two streptogramin antibiotics, linopristin and flopristin, which act synergistically to inhibit the bacterial ribosome. NXL103 is a bactericidal antibiotic and in vivo studies have shown that this novel antibiotic is not affected by either beta-lactam or common macrolide resistance mechanisms. Positive results for a Phase II trial with NXL103 in the treatment of community acquired pneumonia (CAP) were reported towards the end of 2008. NXL103 is currently in a Phase II trial for the treatment of ABSSSI.

About ABSSSI

ABSSSI (Acute Bacterial Skin and Skin Structure Infections) are infections that involve deeper tissue or require surgical intervention (e.g. cellulitis, major cutaneous abscesses, and infected wounds) or are associated with a significant underlying disease that complicates response to therapy. A variety of pathogens may
