About NeurogesX, Inc.

NeurogesX, Inc. (Nasdaq: NGSX) is a San Francisco Bay Area-based biopharmaceutical company focused on developing and commercializing novel pain management therapies. NeurogesX was founded on the concept that use of prescription-strength capsaicin could help manage the pain associated with neuropathic pain conditions. Since its inception, NeurogesX has leveraged its passion to help people with pain to efficiently develop this concept and is now poised to bring its lead product to patients and physicians. In addition, we continue to apply our knowledge and expertise in the development of other novel treatments for pain.

The Company's lead product, Qutenza® (capsaicin) 8% patch, is a localized dermal delivery system containing a prescription strength of capsaicin that is currently approved in the United States and the European Union. Qutenza is now available in the United States for patients with postherpetic neuralgia (PHN). In Europe, Qutenza will be marketed by Astellas Pharma Europe Ltd. (Astellas), the European subsidiary of Tokyo-based Astellas Pharma Inc.

The Company's most advanced product candidate, NGX-1998, is a topically applied liquid formulation containing a high concentration of capsaicin designed to treat pain associated with neuropathic pain conditions such as PHN. NGX-1998 has completed three Phase 1 studies.

The Company's early-stage product pipeline includes pre-clinical compounds which are prodrugs of acetaminophen and various opioids. The Company has evaluated these compounds in vitro and in vivo.
