Paris, France, 13 November 2007 – Novexel, the pharmaceutical company focused on the discovery and development of novel antibiotics and anti-fungals, announced today that its oral steptogramin-class antibiotic, NXL103 (PI + PII), has advanced into Phase II clinical testing.
The double blind, randomized, multi-center, multi-national (Bulgaria, Chile, Croatia, Estonia, Germany, Peru, Poland, Romania, South Africa, Ukraine) trial will investigate the efficacy, safety and tolerance of two doses of NXL103 vs. comparator in a three arm study with 100 patients in each arm, for the treatment of community-acquired pneumonia (CAP) in adults.
Sanofi-aventis holds an option on NXL103 until the end of Phase IIa. Under this agreement, initiation of this clinical trial triggers the payment of a quarterly option fee from sanofi-aventis to Novexel.
Attributes of NXL103 include bactericidal activity against multi-resistant S. pneumoniae, H. influenzae, and S. aureus, including MRSA, and a lack of cross-resistance with other antibiotics. It is further anticipated that NXL103 will have a low propensity to select for or induce resistance.
CAP is one of the most common infectious diseases treated in the ambulatory and hospital setting. Prospective population studies from the UK, Finland, and North America have reported an annual incidence of CAP of between 5 and 11 per 1000 in the adult population [1]. Most cases are mild but mortality among hospitalised patients is high varying from 4-15% [1]. The direct healthcare cost of CAP in the USA has been estimated at $8.4 billion, 92% of the costs being for the inpatient care of 1.1 million patients and the remaining costs for the 4.4 million outpatient consultations [2].
