Auxilium Pharmaceuticals, Inc. Announces Fourth Quarter and Full Year 2008 Financial Results, as Well as Guidance for 2009

Full Year 2008 Net Revenues Increase by 31% to a Record $125.4 Million; 2009 Net Revenues Expected to Be in the Range of $150 Million to $155 Million


MALVERN, PA--(Marketwire - February 18, 2009) - Auxilium Pharmaceuticals, Inc. (NASDAQ: AUXL), a specialty biopharmaceutical company, today announced financial results for the fourth quarter and the year ended December 31, 2008. The Company also highlighted important commercial and clinical development progress during the year 2008 and provided financial and operational guidance for 2009.

For the quarter ended December 31, 2008, Auxilium reported record net revenues of $34.8 million compared to net revenues of $27.7 million in the fourth quarter of 2007, an increase of 25%. For the full year 2008, net revenues totaled $125.4 million compared to net revenues of $95.7 million for the full year 2007, an increase of 31%.

For the quarter ended December 31, 2008, Auxilium reported a net loss of $(12.1) million compared to a net loss of $(11.9) million in the fourth quarter of 2007. For the full year 2008, Auxilium's net loss was $(46.3) million, compared to a net loss of $(40.7) million for the comparable period in 2007.

"We believe 2008 was a transformational year for Auxilium and a huge success. We achieved record revenues for Testim® in 2008, released compelling XIAFLEX Phase III clinical data in Dupuytren's contracture and signed an agreement with Pfizer to be our partner for XIAFLEX™ in Europe," commented Armando Anido, Chief Executive Officer and President of Auxilium. "We continue to believe that XIAFLEX represents a blockbuster opportunity that can provide sustainable long-term growth for the Company and that we are on track to file our U.S. XIAFLEX biologics license application for Dupuytren's contracture in early 2009."

2008 and Recent Highlights:

XIAFLEX:

--  In June 2008, the Company announced positive top-line efficacy and
    safety results from the CORD I and CORD II phase III clinical trials for
    XIAFLEX (clostridial collagenase for injection) in the treatment of
    Dupuytren's contracture. Each of the CORD I and II trials successfully met
    the primary endpoint, a reduction in the angle of a patient's joint
    contracture to less than or equal to 5 degrees of normal, as measured by
    digital goniometry, 30 days after the last injection. The Company also
    released results of a Pharmacokinetic (PK) Study that demonstrated the lack
    of systemic exposure of XIAFLEX in patients treated for Dupuytren's
    contracture.
--  In September 2008, Auxilium announced that the first patients had been
    dosed in the U.S. phase IIb trial of XIAFLEX for the treatment of
    Peyronie's disease.  In February 2009, the Company subsequently announced
    that trial enrollment had been completed and that top line results are
    expected to be released in the fourth quarter of 2009.
--  In December 2008, the Company and Pfizer, Inc. (NYSE: PFE) announced
    their strategic alliance for the development, commercialization and supply
    of XIAFLEX for the treatment of Dupuytren's contracture and Peyronie's
    disease in the 27 member states of the European Union (EU) and 19 other
    European and Eurasian countries. Under the Pfizer agreement, Pfizer made an
    up-front payment of $75 million to Auxilium and will make up to $410
    million in potential milestone payments, with $150 million tied to
    regulatory milestones and $260 million based on commercialization
    milestones. Auxilium will also receive significant increasing, double-
    digit, tiered royalties based on sales of XIAFLEX in Pfizer's territories.
    

TESTIM:

--  Testim revenues were up 31% over the prior year to $125.2 million.
--  Testim prescriptions grew by 26.5% in 2008 according to National
    Prescription Audit (NPA) data from IMS Health, Inc. (IMS), a leading market
    research firm.
--  Total prescriptions for the testosterone replacement gel market
    segment grew 15.2% in 2008 according to NPA data from IMS.
--  In December 2008, Testim's market share of the gel segment reached a
    record 22.3% versus 21.5% in December 2007, according to IMS.
--  In December 2008, Auxilium and Ferring International S.A. announced an
    exclusive agreement for the European distribution and license rights to
    Testim.  The Company and Ipsen Pharma GmbH agreed to mutually terminate
    their distribution agreement for Testim in Europe and other countries
    outside North America and Japan.
--  In December 2008, after receiving a notice of an Abbreviated New Drug
    Application (ANDA) filing by Upsher-Smith Laboratories, Inc. (Upsher-Smith)
    containing a Paragraph IV certification for testosterone gel in October
    2008, Auxilium and CPEX Pharmaceuticals, Inc. (CPEX) filed a lawsuit
    against Upsher-Smith for infringement of CPEX's U.S. Patent No. 7,320,968,
    which covers Testim, 1% testosterone gel.
    

COMPANY HIGHLIGHTS:

--  In 2008, the Company continued to build out its management team with
    seasoned executives:
    --  Dr. Anthony DelConte assumed the newly created position of Chief
        Medical Officer;
    --  Mr. Will Sargent assumed the newly created position of Vice
        President, Investor Relations and Corporate Communications;
    --  Dr. Laura Offutt joined as Vice President, Medical Affairs;
    --  Dr. Wayne Herber assumed the newly created position of Vice
        President, Process Development;
    --  Mr. Michael Cowan was promoted to Senior Vice President,
        Manufacturing; and
    --  Mr. Scott Wilhoit was promoted to Vice President, XIAFLEX Marketing
        and Managed Markets.

2009 Financial and Operational Guidance

For 2009, Auxilium anticipates that:

--  net revenues will be in the range of $150 million to $155 million;
--  research and development spending will be in the range of $49 million
    to $53 million, which includes $4 million to $5 million of stock-based
    compensation cost;
--  selling, general and administrative expenses will be in the range of
    $116 million to $121 million, which includes $12 million to $14 million of
    stock-based compensation cost;
--  net loss will be in the range of $50 million to $55 million; and
--  total stock-based compensation expense will be in the range of $16
    million to $19 million.
    

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

--  file the Biologics License Application (BLA) for approval of XIAFLEX
    for the treatment of Dupuytren's contracture with the U.S. Food and Drug
    Administration (FDA) in early 2009;
--  prepare the Company's commercial organization for a potential priority
    review of the XIAFLEX BLA from the FDA; 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, February 18, 2009 at 10:00 a.m. EST.

Fourth Quarter 2008 Financial Detail

For the quarter ended December 31, 2008, Auxilium reported net revenues of $34.8 million compared to net revenues of $27.7 million in the fourth quarter of 2007, an increase of 25%.

The net loss for the fourth quarter of 2008 was $(12.1) million, or $(0.29) per share, compared to a net loss of $(11.9) million, or $(0.29) per share, reported for the fourth quarter of 2007. Net loss for the fourth quarter of 2008 includes total stock-based compensation expense of $3.7 million, compared to $1.8 million for the fourth quarter of 2007.

Gross margin on net revenues was 76.3% for the quarter ended December 31, 2008 compared to 73.9% for the comparable period in 2007. 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 improvement in gross margin reflects the impact of year-over-year price increases and the decline in low margin international shipments, partially offset by an increase in coupon usage.

Research and development spending for the quarter ended December 31, 2008 was $14.6 million, compared to $14.5 million for 2007. Although the overall spending was comparable year over year, there was a significant reduction in clinical development costs, offset by increases in regulatory costs and manufacturing costs at Horsham.

Selling, general and administrative costs for the quarter ended December 31, 2008 were $24.4 million, compared to $18.9 million in the comparable 2007 period. 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 launch of XIAFLEX.

As of December 31, 2008, Auxilium had $113.9 million in cash, cash equivalents and short-term investments, compared to $46.4 million at September 30, 2008.

Full Year 2008 Financial Detail

For the full year 2008, net revenues totaled $125.4 million, compared to net revenues of $95.7 million for the year 2007, an increase of 31%.

Auxilium reported a net loss of $(46.3) million, or $(1.12) per share, for the full year 2008, compared to a net loss of $(40.7) million, or $(1.07) per share, for the full year 2007. Net loss for 2008 includes total stock-based compensation expense of $11.7 million, compared to $6.0 million for the full year 2007.

Gross margin on net revenues was 76.5% for the full year 2008, compared to 74.3 % for the full year 2007.

Research and development costs for the full year 2008 were $54.5 million compared with $42.8 million for the full year 2007.

Selling, general and administrative expenses totaled $89.5 million for the year ended December 31, 2008, compared with $72.8 million for the year-ago period.
