CRANBURY, NJ -- (MARKET WIRE) -- 02/22/07 -- Valera Pharmaceuticals (NASDAQ: VLRX), a specialty pharmaceutical company focused on the development, acquisition and commercialization of products for the urology and endocrinology markets, today announced financial results for the three months and full year ended December 31, 2006.

Valera also noted product milestones and other key events which occurred since the Company's last earnings report, including:

--  Initiation of Phase I/II studies for its naltrexone implant for drug
    addiction

--  The start of an expanded study for its biodegradable ureteral stent

--  Partnership with Indevus Pharmaceuticals for the co-promotion of
    VANTAS®, Valera's twelve month LHRH implant for prostate cancer

--  Proposed acquisition of Valera by Indevus in a tax-free stock-for-
    stock merger transaction, anticipated to close in April 2007
    

Fourth Quarter and Full Year 2006 Financial Results

Net product sales of VANTAS during the fourth quarter of 2006 were approximately $3.2 million, primarily representing 2,324 units sold in the United States at an average net selling price of $1,370. This compares to fourth quarter 2005 net sales of approximately $5.2 million, based on 2,868 units sold at an average net selling price of $1,801. This decline in product sales in the fourth quarter of 2006 compared to the fourth quarter of 2005 reflects, in part, pricing pressure for the class of LHRH drugs, exacerbated by changes in Medicare reimbursement rates, including certain Medicare carriers adopting a policy that segregates twelve-month products from other dosages, including one, three, four and six month injectable products, and reimbursing the injectables at higher annual rates.

Valera noted that fourth-quarter 2006 net product sales of approximately $3.2 million represented a sequential improvement of 10% from approximately $2.9 million in the third quarter of 2006. Correspondingly, U.S. VANTAS sales of 2,324 units in the fourth quarter of 2006 were up 18% from 1,968 units sold in the third quarter of 2006, offset by a 7% decline in average unit selling price, respectively, to $1,370 from $1,478. As previously reported, Valera believes that units shipped in the third quarter of 2006 had been adversely impacted by a loss in re-implantation procedures in that quarter due to the interruption in VANTAS shipments in the third quarter of 2005.

Also, in keeping with Valera's previously noted commitment to pursue options to mitigate the impact of the Medicare pricing environment, during the fourth quarter of 2006 the Company continued to shift more of its sales resources to attempt to capture non-Medicare market share. While still in its early stages, Valera believes that this strategy will open greater opportunities to leverage the advantages of its twelve month VANTAS implant, including the convenience and efficiency for physicians in administering to the needs of their patients. In order to broaden the market penetration of VANTAS, on December 12, 2006 Valera entered into a co-promotion agreement with Indevus Pharmaceuticals (NASDAQ: IDEV) under which Indevus' sales force began co-promoting VANTAS in the United States in mid-January 2007. Indevus and Valera also agreed to the acquisition of Valera by Indevus in a tax-free stock-for-stock merger, subject to approval of each company's shareholders and other customary closing conditions. Correspondingly, 2006 financial results reported by Valera include approximately $0.8 million in merger related costs, primarily reflected in fourth quarter G&A expenses.

Net product sales for the years ended December 31, 2006 and 2005 were approximately $17.8 million and $26.8 million, respectively. The 33% decrease in net product sales was primarily due to lower net average selling prices due to decreased Medicare reimbursement rates of VANTAS as well as increased competition around pricing in the class of LHRH drugs. For the year ended December 31, 2006, Valera sold 11,663 units of VANTAS in the United States at a net average selling price of $1,526 per unit as compared to 11,514 units at a net average selling price of $2,327 for the year ended December 31, 2005. Also, in 2006, as a result of pre-launch shipments of VANTAS for Canada, Valera sold a total 169 units to Paladin Labs, its marketing partner in Canada. Thus, worldwide unit sales of VANTAS increased by 3%, or 318 units, for the year ended December 31, 2006, as compared to the year ended December 31, 2005.

As of December 31, 2006, cash and cash equivalents were approximately $14.1 million, as compared to $2.3 million at December 31, 2005. The net increase was primarily due to the proceeds Valera received from the initial public offering of common stock in February 2006.

Milestones and Key Events

Naltrexone Implant: During the fourth quarter of 2006, the Food and Drug Administration (FDA) accepted Valera's Investigational New Drug Application and Valera finalized all administrative arrangements with Johns Hopkins necessary to begin clinical studies for VP004, a subcutaneous implant utilizing Valera's Hydron technology to deliver naltrexone, over an extended period of time, for the treatment of opioid addiction. This Phase I/II clinical trial involves an open label study of the naltrexone implant in approximately a dozen healthy volunteers with a history of opioid abuse. The primary objective of the study is to investigate the extent of opiate blockade following morphine challenges. The lead investigator is the pioneering addiction researcher and renowned authority on naltrexone, Donald Jasinski, M.D., Professor of Medicine, Chief Center for Chemical Dependence, Johns Hopkins Bayview Medical Center.

Ureteral Stent: On November 8, 2006, Valera announced that it completed proof-of-concept studies on a flexible, biodegradable polymer-based ureteral stent. The Company has since advanced this development program in a large porcine model study to establish safety and effectiveness necessary to support the submission of a 510k device application with the FDA. Valera believes that the successful development a pliable, biodegradable ureteral stent, which could be voided naturally from the body with the discharge of urine, potentially represents a significant advance over existing plastic and metallic ureteral stents which are non-degradable and require physician intervention to extract from the body. Valera further noted that, pending the outcome of the study, the 510k submission could occur by the end of 2007.

Indevus Pharmaceuticals: In December 2006, Indevus and Valera entered into to a co-promotion agreement for VANTAS in the United States. Effective January 15, 2007 the number of sales professionals essentially quadrupled to approximately 105 representatives to promote and support future growth opportunities for VANTAS. Additionally, the co-promotion agreement provides Valera with the option to elect to enter into negotiations with Indevus to grant Indevus a co-exclusive right to co-promote SUPPRELIN®-LA. Separately, Valera announced in December 2006 that it entered into a merger agreement with Indevus pursuant to which Indevus will acquire Valera in a tax-free stock-for-stock merger transaction. In a joint press release on December 12, 2006, David S. Tierney, M.D., President and CEO of Valera, commented on the merger agreement, noting, "As we entered into discussion for a co-promotional arrangement with Indevus, it became apparent that our product offerings, the patient and physician benefits, and the potential for shareholder returns would be enhanced by leveraging the strengths of the combined companies." Additional information on the proposed merger of Indevus and Valera is provided below.
