NeurogesX, Inc. Reports Third Quarter 2007 Financial Results

SAN MATEO, Calif., Nov. 14 /PRNewswire-FirstCall/ -- NeurogesX, Inc. , a biopharmaceutical company focused on developing and commercializing novel pain management therapies, today reported financial results for the third quarter ended September 30, 2007 and provided an update on recent clinical developments.

Anthony DiTonno, President and CEO, commented, “The third quarter was an exceptional period for NeurogesX and we are pleased with the progress of our clinical development program for our lead product candidate, NGX-4010. During the quarter, we reported positive results from our second successful pivotal study of NGX-4010 in postherpetic neuralgia (PHN) and received confirmation that our Marketing Authorization Application (MAA) for the product was accepted for review by the European Medicines Agency (EMEA). With enrollment completed in our ongoing study of NGX-4010 in painful HIV-distal sensory polyneuropathy (HIV-DSP), we remain on schedule to report top line data near the end of the first quarter of 2008. We are also on track for a New Drug Application (NDA) submission, anticipated in the second half of next year.”

Mr. DiTonno continued, “We also recently announced the expansion of our senior management team and board of directors, reflecting our ongoing, strategic efforts to strengthen and broaden our resources in support of the continuing development and potential commercialization of NGX-4010. We continue to evaluate the development program for NGX-4010 in painful diabetic neuropathy and we are preparing for an investigational new drug application (IND) submission for our product candidate NGX-1998 in the first half of 2008.”

Recent Developments

Positive top-line results were reported from a second successful pivotal study of NGX-4010 for the treatment of PHN. The multi-center, double-blind, controlled Phase 3 study met its pre-specified primary endpoint: the reduction in pain from baseline to study weeks 2-8 (p=0.01). Additionally, significant results were achieved for study weeks 2-12 (p<0.02), a secondary endpoint. All other secondary endpoints, including 30% and 50% responder analyses, were also met. The study evaluated 416 patients enrolled at study sites in both the United States and Canada.

The MAA submitted for NGX-4010, NeurogesX’ lead product candidate for the treatment of peripheral neuropathic pain, was accepted for review by the EMEA. Completion of the acceptance period (or validation) signified that the EMEA had begun the review of NeurogesX’ MAA. The Company’s submission is based upon existing clinical trial data, which as of the date of the filing included its first two successful Phase 3 studies, one each in PHN and HIV-DSP. The review process is being coordinated by the EMEA under the centralized procedure, which, if resulting in approval, may provide one marketing authorization for all European Union member states, as well as Iceland, Liechtenstein and Norway.

Enrollment reached completion in clinical study C119, a second Phase 3 clinical study of NGX-4010 for the treatment of painful HIV-DSP. C119 is a randomized, double-blind, controlled study that has enrolled over 480 patients at study sites in the United States, the United Kingdom, Australia and Canada.

NeurogesX expanded its board of directors and senior management team. Bruce A. Peacock, a seasoned pharmaceutical and biotechnology industry executive, joined the NeurogesX board of directors. Susan Rinne and Russell Kawahata, Ph.D, joined NeurogesX as Vice President of Regulatory Affairs and Vice President of Pharmaceutical Science, respectively.

Third Quarter 2007 Financial Results

For the quarter ended September 30, 2007, total operating expenses were approximately $9.5 million, including $0.4 million of non-cash stock-based compensation expense, compared to total operating expenses of approximately $5.9 million, including $0.4 million of non-cash stock-based compensation, in the third quarter of 2006. The increase in operating expenses on a year-over- year basis was attributable to expenses related to increased clinical study activity associated with the Phase 3 trial in painful HIV-DSP, regulatory expenses and filing fees for the MAA submission in Europe, higher general and administrative expenses due to increased infrastructure in support of NeurogesX’ growth, and higher expenses associated with being a public company and increased marketing related expenses in connection with pre- commercialization market research and other pre-launch activities.

For the third quarter of 2007, net loss was approximately $9.2 million compared to a net loss of $5.6 million in the third quarter of 2006. Net loss per share attributable to common stockholders, which includes the non-cash charges for accretion of preferred stock to redemption value, was a loss of $0.68 per share and $23.20 per share for the three months ended September 30, 2007 and 2006, respectively, based on weighted average shares of 13,429,471 and 375,015, respectively. The weighted average shares used in computing loss per share attributable to common stockholders exclude anti-dilutive securities such as stock options and warrants and also redeemable preferred stock in periods prior to their conversion to common stock upon completion of NeurogesX’ initial public offering.

Cash, cash equivalents and short-term investments were $39.3 million as of September 30, 2007.
