BERKELEY, Calif., March 14, 2012 (GLOBE NEWSWIRE) -- XOMA Corporation (Nasdaq:XOMA), a leader in the discovery and development of therapeutic antibodies, today announced its financial results and operational highlights for the fourth quarter and year ended December 31, 2011.

"While the first half of 2011 included some disappointments, we had a crucial success in attracting a world-class pharmaceutical company, Les Laboratoires Servier, to become our partner for our lead asset gevokizumab. In mid 2011, we were able to recruit Paul Rubin, MD, as our Chief Medical Officer," stated John Varian, XOMA's Chief Executive Officer. Mr. Varian added, "After joining XOMA as Interim CEO in September 2011, I worked with Paul and the rest of the management team to take significant actions to make XOMA a stronger company. These actions were two-fold. First, we significantly expanded the gevokizumab development program. Second, to fund this investment, we streamlined XOMA and moved the Company away from non-differentiating activities. The expanded clinical approach for gevokizumab was announced in November 2011, and the streamlining, which resulted in a $14 million reduction in recurring costs, was announced on January 5, 2012.

"As you have seen from us in the early months of 2012, we remain focused on investing in value-creating activities. We believe XOMA will conclude 2012 with the gevokizumab global Phase 3 program ongoing, results in hand from our Phase 2 proof-of-concept study in moderate to severe inflammatory acne, and our second and third proof-of-concept Phase 2 studies underway," Mr. Varian continued. "I have confidence we have the ability to achieve these milestones and the depth of knowledge and creativity of our team will lead to additional avenues upon which we can build value for XOMA and its shareholders."

XOMA had total revenues of $58.2 million in 2011, compared with $33.6 million in 2010. The increase in revenues in 2011 compared with 2010 was due primarily to payments made by Les Laboratoires Servier (Servier) throughout 2011 for gevokizumab development.

XOMA had a net loss of $32.7 million, or $1.04 per share, for the year ended December 31, 2011, compared with net loss of $68.8 million, or $3.69 per share, for the year ended December 31, 2010. Research and development expenses in 2011 decreased to $68.1 million compared with $77.4 million in 2010, primarily reflecting decreased spending on gevokizumab-related clinical trials during the third and fourth quarters of 2011. General and administrative expenses were $24.0 million in 2011 and $23.3 million in 2010.

For the fourth quarter ended December 31, 2011, XOMA had total revenues of $9.8 million and a net loss of $11.7 million, or $0.34 per share, compared with total revenues of $9.6 million and net loss of $17.8 million, or $0.84 per share, for the quarter ended December 31, 2010.

At December 31, 2011, XOMA had cash and cash equivalents of $48.3 million, compared with $37.3 million at December 31, 2010. XOMA received from Servier approximately $35 million in cash related to the companies' Collaboration and License Agreement for gevokizumab, including an upfront payment of $15 million and a EUR15 million loan, in January 2011. In December 2011, XOMA secured a $10 million loan from GE Capital.

2012 Organizational Changes to Focus on Value-Creating Activities and Fourth Quarter 2011 Operational Highlights

• On January 5, 2012, XOMA announced the appointment of John Varian as Chief Executive Officer, in addition to his continued position as a member of the Board of Directors. Concurrently, Mr. Varian announced the streamlining of XOMA's operations to focus on value-creating activities, primarily the expansion of gevokizumab's clinical development program. The streamlining resulted in

• a personnel reduction of 84 positions
• the decision to outsource Phase 3 and commercial-scale manufacturing
• the elimination of internal research functions that were non-differentiated or obtainable cost-effectively through contract service providers
• a reduction in G&A spending of 20% to support the leaner organization
• the decision to complete the biodefense contracts XOMA has in place but not actively pursue future contracts.

• In November 2011, the Company announced the expansion of XOMA's Phase 3 program for gevokizumab to the broader indication of non-infectious uveitis (NIU). NIU is a broad-spectrum ocular disorder, which includes Behcet's uveitis, affecting an estimated 150,000 people in the United States. The Company expects to begin its global Phase 3 program in the second quarter of 2012.
• In December 2011, XOMA launched a Phase 2 proof-of-concept trial to determine gevokizumab's efficacy in treating moderate to severe inflammatory acne. This study is the first in a series of three proof-of-concept Phase 2 studies that XOMA is conducting to expand the value of gevokizumab. 
• In December 2011, the Company secured a $10 million term loan from GE Capital.
• In October 2011, the Company was awarded a new U.S. government contract for up to $28 million over five years to develop broad-spectrum antitoxins for the treatment of human botulism poisoning.
• In December 2011, XOMA changed its jurisdiction of incorporation from Bermuda to Delaware.

Guidance

The Company reaffirmed the anticipated cash used in ongoing operating activities during 2012 to be approximately $35 million, as announced on January 5, 2012.

About Gevokizumab

Gevokizumab (XOMA 052) is a potent monoclonal antibody with the potential to treat patients with a wide variety of inflammatory diseases and other diseases. Gevokizumab binds strongly to interleukin-1 beta (IL-1 beta), a pro-inflammatory cytokine that has been shown to be involved in Behcet's and other forms of non-infectious uveitis, cardiovascular disease, and other auto-inflammatory diseases. By binding to IL-1 beta, gevokizumab inhibits the activation of the IL-1 receptor, thereby modulating the cellular signaling events that produce inflammation.

Les Laboratoires Servier is XOMA's development and commercialization partner for gevokizumab. XOMA holds rights to gevokizumab in the U.S. and Japan for non-cardiovascular indications, including non-infectious uveitis and acne for which clinical studies are ongoing.

About Non-infectious Uveitis

The term uveitis broadly refers to the inflammatory diseases that affect the portion of the eye known as the uvea, which is the middle of three layers that surround the eye. People with uveitis may experience decreased vision, pain, light sensitivity, and floaters. Uveitis may be caused by an infection that is commonly treated with an antimicrobial agent, or by an unknown pathogen triggering inflammation, called non-infectious uveitis.

The most common form of uveitis affects the front of the eye and is known as anterior uveitis. Other forms include intermediate uveitis, posterior uveitis, and pan uveitis. These types differ in that they all include involvement of the back portions of the eye. Posterior uveitis refers to inflammation in the retina and the choroid, and it may result from a different immune response trigger. Pan-uveitis refers to inflammation of all three major parts of the eye. Behcet's uveitis is a well-known form of pan-uveitis. Due to the swelling of tissues critical to vision, intermediate, posterior, and pan-uveitis (which collectively make up NIU) can lead to blindness if not treated.

The only FDA-approved treatment regimen for intermediate, posterior, and pan-uveitis is corticosteroid therapy. These may be given orally or systemically, injected directly into the eye or surrounding areas, or delivered via slow-release polymers that are inserted into the eye. The fact that physicians use other non-FDA approved drugs in addition to corticosteroids to treat non-infectious uveitis underscores the need for new treatment options.

About XOMA

XOMA discovers and develops innovative antibody therapeutics. XOMA's lead antibody drug candidate is gevokizumab (XOMA 052), a humanized antibody that modulates the inflammatory cytokine interleukin-1 beta, or IL-1 beta. In collaboration with the Company's partner, Les Laboratoires Servier (Servier), XOMA expects to initiate global Phase 3 clinical development of gevokizumab to treat non-infectious uveitis, including the subset of patients with Behcet's uveitis, in 2012. Separately, XOMA has launched a Phase 2 proof-of-concept program for gevokizumab to evaluate additional indications for further development, including moderate-to-severe inflammatory acne.

In order to retain the value of XOMA's discoveries and its future revenue potential, XOMA made a strategic decision to establish a commercial capability. To implement this strategy, the Company established its U.S. commercial operations through the acquisition of U.S. rights to Servier's ACEON® (perindopril erbumine), a marketed angiotensin converting enzyme (ACE) inhibitor. The agreement with Servier includes a portfolio of fixed-dose combination product candidates where perindopril is combined with other active ingredients to treat hypertension. XOMA has the right to develop and commercialize one of these product candidates for the U.S. market and options to develop and commercialize two more.

Through its unique discovery platform, the Company is focused on discovering and developing allosteric modulating antibodies that combine the beneficial pharmacology of small molecule drugs with the target specificity of antibodies. Among these novel discoveries are two new classes of fully human antibodies: XMetA partially activates the insulin receptor, and XMetS sensitizes the insulin receptor. These two programs represent distinct and potentially breakthrough therapeutic approaches to the treatment of patients with diabetes. XOMA is headquartered in Berkeley, California.
