Auxilium Pharmaceuticals, Inc. Announces First Quarter 2009 Financial Results and Operational Highlights

XIAFLEX(TM) BLA Receives Priority Review; XIAFLEX Commercial Organization Preparing for Potential August FDA Approval; Total Revenues of $34.7 MM, up 28% Versus Q1 of 2008


MALVERN, PA--(Marketwire - May 6, 2009) - Auxilium Pharmaceuticals, Inc. (NASDAQ: AUXL), a specialty biopharmaceutical company, today announced financial results and operational highlights for the quarter ended March 31, 2009. For the first quarter of 2009, Auxilium reported net revenues of $34.7 million compared to net revenues of $27.1 million in the first quarter of 2008. The net loss for the first quarter of 2009 was $(13.2) million, or $(0.31) per share, compared to a net loss of $(12.3) million, or $(0.30) per share, reported for the first quarter of 2008.

On April 28, 2009, the U.S. Food and Drug Administration (FDA) accepted for Priority review the Company's Biologics License Application (BLA) for XIAFLEX™ (clostridial collagenase for injection) for the treatment of Dupuytren's contracture filed on February 27, 2009. The FDA has provided a Prescription Drug User Fee Act (PDUFA) goal date of August 28, 2009 for completion of its review of the XIAFLEX BLA. If approved by the FDA, Auxilium expects to launch XIAFLEX for Dupuytren's contracture in the U.S. within 60 days of FDA approval.

"Receiving Priority review from the FDA is a significant achievement in the development pathway of XIAFLEX. We are preparing our commercial organization for a potential U.S. XIAFLEX launch in the second half of 2009 and believe that we have a comprehensive plan in place to launch approximately 60 days after approval," said Armando Anido, Chief Executive Officer and President of Auxilium. "As for Testim®, our total U.S. prescriptions for the first quarter kept pace with the testosterone replacement gel market and increased 14.1% from the first quarter of 2008, according to National Prescription Audit (NPA) data from IMS Health, Inc. (IMS)."

First Quarter Operational Highlights:

XIAFLEX:

--  On February 27, the Company filed its BLA for Dupuytren's contracture
    with FDA.  The filing included data from 1,082 subjects and over 2,600
    injections of XIAFLEX. FDA accepted the Company's BLA and granted Priority
    review on April 28, 2009.
--  Key Commercial and Medical personnel have been added in anticipation
    of a potential launch in the second half of 2009.
--  The Company enrolled over 120 patients in its phase IIb study of
    XIAFLEX for Peyronie's disease on January 30, completed all dosing on April
    30, and expects to announce top-line results in the fourth quarter of 2009.
    

TESTIM:

--  According to IMS, 138,164 total prescriptions for Testim were
    dispensed in the first quarter of 2009, a growth of 14.1% over the first
    quarter of 2008.
--  Total prescriptions within the gel segment of the testosterone
    replacement therapy market in the U.S. grew 14.9% versus the first quarter
    of 2008, according to IMS.
--  Testim ended the month of March with a 21.6% share of total
    prescriptions for testosterone gels in the U.S., down from 21.9% at the end
    of March 2008, according to IMS.
    

MANAGEMENT TEAM ADDITIONS:

--  In the first quarter of 2009, the Company continued to build out its
    management team.  Dr. Jim Tursi joined Auxilium as Vice President, Clinical
    Affairs.  Dr. Tursi was previously at GlaxoSmithKline Biologicals (GSK)
    where he directed the cross-functional team preparing their cervical cancer
    vaccine for launch in North America.  Prior to GSK, he was Senior Medical
    Director of Medical Affairs/Clinical Development at Procter and Gamble
    Pharmaceuticals and had responsibility for Women's Health, Urology, and
    Gastroenterology products.  Dr. Tursi received his MD from the Medical
    College of Pennsylvania and completed residency training in obstetrics and
    gynecology at The Johns Hopkins Hospital.
    

Updated 2009 Financial and Operational Guidance

Based on the FDA's acceptance of the XIAFLEX BLA for Priority review, Auxilium has updated its 2009 guidance. The Company is not including any sales of XIAFLEX or the costs of the 75 to 100 person XIAFLEX sales force that it anticipates hiring (including certain training and marketing costs) in its updated guidance because the amount of such sales and costs that may be realized in 2009, if any, are dependent upon the launch date of XIAFLEX which is not yet known. The Company anticipates:

--  net revenues remain unchanged at $150 million to $155 million for
    2009;
--  research and development investment will be in the range of $45
    million to $50 million, which includes $4 million to $5 million of stock-
    based compensation cost.  This is down from previous guidance of $49
    million to $53 million;
--  selling, general and administrative expenses will be in the range of
    $120 million to $130 million up from previous guidance of $116 million to
    $121 million, which does not include the costs of hiring and training the
    sales force, and includes $12 million to $14 million of stock-based
    compensation cost;
--  net loss will be in the range of $55 million to $60 million compared
    to the previous guidance of $50 million to $55 million; and
--  total stock-based compensation expense will remain in the range of $16
    million to $19 million.
    

With respect to the clinical and commercialization program for XIAFLEX, Auxilium expects to:

--  prepare the Company's commercial organization to execute a successful
    U.S. XIAFLEX launch within 60 days of the FDA's action date; and
--  release top-line results from the double-blind phase IIb clinical
    trial for XIAFLEX for the treatment of Peyronie's in the fourth quarter of
    2009.
    

Information concerning select assumptions will be discussed during the conference call today, May 6, 2009 at 10:00 a.m. EDT.

First Quarter 2009 Financial Details

For the quarter ended March 31, 2009, Auxilium reported net revenues of $34.7 million compared to net revenues of $27.1 million in the first quarter of 2008. There was $1.3 million of ex-U.S. partner milestone revenue recognition and shipments of Testim in the first quarter of 2009, compared to $0.2 million of ex-U.S. partner milestone revenue recognition in the first quarter of 2008. The Company also recognized $0.9 million in revenues related to the amortization of upfront payments related to XIAFLEX. The net loss for the first quarter of 2009 was $(13.2) million, or $(0.31) per share, compared to a net loss of $(12.3) million, or $(0.30) per share, reported for the first quarter of 2008. Net loss for the first quarter of 2009 includes total stock-based compensation expense of $4.5 million, compared to $2.1 million for the first quarter of 2008.

Gross margin on net revenues was 77.3% for the quarter ended March 31, 2009 compared to 77.9% for the comparable period in 2008. Gross margin reflects the cost of product sold as well as royalty payments made to the Company's licensor on the sales of Testim. The decrease in the gross margin rate is the result of a 2008 one-time manufacturing fee rebate and higher coupon usage in 2009, partially offset by the impact of year-over-year price increases on U.S. Testim revenues and the increase in amortization of upfront and milestone payments.

Research and development spending for the quarter ended March 31, 2009 was $13.5 million, compared to $13.2 million for 2008. Although the overall spending was comparable year over year, there was a significant reduction in clinical development costs primarily related to fewer XIAFLEX related clinical trials being conducted in 2009, offset by increases in regulatory costs and manufacturing costs at our Horsham manufacturing facility.

Selling, general and administrative expenses totaled $26.4 million for the quarter ended March 31, 2009 compared with $21.0 million for the year-ago quarter. The increase was primarily due to higher compensation costs associated with FAS 123R, costs incurred in defense of our Testim intellectual property and investments in preparing for the potential U.S. launch of XIAFLEX.

As of March 31, 2009, Auxilium had $90.2 million in cash and cash equivalents compared to $113.9 million on December 31, 2008.
