Press Release: Renovis Announces Achievement of Milestones in VR1 Collaboration with Pfizer

Renovis Announces Achievement of Milestones in VR1 Collaboration with Pfizer SOUTH SAN FRANCISCO, June 8 -- Renovis, Inc. , a biopharmaceutical company focused on the discovery and development of drugs for major medical needs in the areas of neurological and inflammatory diseases, today announced the achievement of two milestones in its research collaboration with Pfizer Inc. to discover and develop VR1 antagonists for the potential treatment of pain and other indications. The milestones include the placement of a second product candidate from the VR1 program into IND-enabling studies as well as completion of certain studies with a previously nominated compound. In addition to triggering aggregate payments of $4.5 million from Pfizer to Renovis, these milestones illustrate the continued productivity of the Company's joint effort with Pfizer. "VR1 antagonists have the potential to become breakthrough treatments for chronic pain and several other important indications," said Corey S. Goodman, Ph.D., President and Chief Executive Officer. "Our goal for the VR1 program with Pfizer has been to discover and develop multiple product candidates to address the needs of patients in these areas. With the recent nomination of a second candidate for IND-enabling studies we believe we are making excellent progress toward this goal." "The joint project team has made significant progress since the companies began working together on the VR1 program in the middle of 2005," said Michael G. Kelly, Ph.D., Senior Vice President of Research and Development. "The program has already identified clinical candidates and we now look to be in the clinic during the first half of next year." 2007 Financial Guidance Financial projections involve a high level of uncertainty due, among many factors, to the variability involved in predicting requirements of drug discovery and clinical development activities and the potential for Renovis to enter into new licensing agreements or strategic collaborations. We plan to update financial guidance for 2007, as necessary, when we release results for each quarter or upon the announcement of material corporate events. For the year ending December 31, 2007, the Company has updated its previously announced revenue guidance and now anticipates: -- total contract revenue from existing agreements of $9.0 million to $10.0 million; and -- total operating expenses of $28.0 million to $32.0 million, excluding non-cash, stock-based compensation to be recognized in accordance with SFAS No. 123R and $1.1 million in restructuring expense.
