Second-Quarter and First-Half 2010 Financial Results

Revenue for the second quarter and six months ended June 30, 2010, increased to $5.7 million and $11.2 million, respectively, compared with $4.1 million and $8.3 million, respectively, in 2009. Revenue was primarily earned through the company's strategic collaborations with Pfizer, for the development of CD20-directed candidates, including SBI-087, and Abbott, for the development of CD37-directed targets, including TRU-016.

During the second quarter and first half of 2010, Trubion recognized $3.8 million in revenue from its Abbott collaboration. The $3.8 million includes recognition of $1.1 million from the $20 million upfront fee and $1.4 million equity premium received from Abbott, as well as $2.7 million earned through collaborative research.

The increase in revenue from the Abbott partnership was partially offset by lower revenue generated by Trubion's collaboration with Pfizer. The decrease in revenue was attributed to lower costs related to the retreatment studies of TRU-015 for rheumatoid arthritis (RA) as well as a decrease in the amount of reimbursable legal fees. Revenue earned from Trubion's partnership with Pfizer during the first half of the year was $7.4 million, which included $2.4 million for recognition of the $40 million upfront fee received in January 2006 and $5.0 million earned through collaborative research. This is compared with $8.3 million earned in revenue during the first half of 2009, which was composed of $2.4 million for the recognition of the $40 million upfront fee and $5.9 million in revenue earned through collaborative research.

Total operating expenses for the second quarter and first half of 2010 were $11.3 million and $22.8 million, respectively, compared with $10.7 million and $25.9 million in 2009. The increase in operating expenses during the second quarter was due to increased clinical development costs related to the initiation of the Phase 1/2 clinical trial of TRU-016 (16201) and increased TRU-016 manufacturing costs. These increases were partially offset by lower personnel costs.

Net loss for the second quarter and six months ended June 30, 2010, decreased to $5.7 million, or $0.28 per diluted common share, and $11.8 million, or $0.58 per diluted common share, respectively. This is compared with a net loss of $6.7 million, or $0.37 per diluted common share, and $17.7 million, or $0.99 per diluted common share, in 2009.

Trubion had $42.1 million in cash, cash equivalents and investments as of June 30, 2010, compared with $54.8 million as of Dec. 31, 2009.

"During the course of the past year we've trimmed expenses and have worked with our partners to prioritize product candidates that demonstrate the potential for safer, more effective and more convenient treatments," said Steve Gillis, Ph.D., executive chairman and acting president of Trubion. "In the coming months, we will work diligently with Emergent in an effort to finalize our recently announced merger in a timely manner, and we will continue to pursue our corporate objectives and product and collaboration milestones."

Recent milestones

    --  On Aug. 12, 2010, Trubion announced the signing of a definitive merger
        agreement with Emergent BioSolutions Inc. (NYSE: EBS), in which Emergent
        has agreed to acquire Trubion. Under the terms of the agreement, each
        share of Trubion common stock will be converted into the right to
        receive an upfront payment of $1.365 per share in cash and 0.1641 shares
        of Emergent BioSolutions common stock. The upfront payment represents a
        value of $4.55 per share, or approximately $96.8 million, based on
        Trubion's total common shares outstanding, the net value of dilutive
        stock options, and the trading average of Emergent BioSolutions common
        stock for the five days prior to the signing of the definitive
        agreement. Trubion Pharmaceuticals stockholders will also receive one
        Contingent Value Right (CVR) per share, which will entitle the holder to
        receive cash payments based upon achievement of predefined milestones.
        The total potential aggregate value of the CVRs is $38.7 million over a
        36-month period, post-closing. The transaction has been approved by the
        boards of directors of both companies and is subject to customary
        closing conditions, including the approval of the acquisition by
        stockholders of Trubion, and the expiration or termination of the
        applicable waiting period under the Hart-Scott-Rodino Antitrust
        Improvements Act of 1976. The acquisition is expected to close in the
        fourth quarter of 2010.
    --  In June, the Board of Appeal for the European Patent Office (EPO) ruled
        in Trubion's favor to uphold an earlier ruling to revoke European Patent
        1176981. This patent is owned by Genentech and Biogen Idec and is
        generally directed to the use of an anti-CD20 antibody for the treatment
        of RA. Trubion filed its opposition to the patent in August 2006 and
        subsequently announced in September 2008 that the Opposition Division of
        the EPO had revoked the European patent in its entirety. Genentech and
        Biogen Idec appealed the decision in February 2009. With the EPO's June
        2010 ruling, no further appeals can be made with regard to revoked
        claims, but Genentech and Biogen Idec can pursue a claim limited to the
        use of rituximab in combination with methotrexate to treat RA. The EPO's
        decision opens the door for the development of safer, more effective and
        more convenient treatment options for patients.
    --  Also in June, Trubion presented positive data from a Phase 1 study of
        SBI-087 for RA and a Phase 1 study of SBI-087 for systemic lupus
        erythematosus (SLE) at the 2010 annual congress of the European League
        Against Rheumatism (EULAR). Data from both studies demonstrated that
        SBI-087 is generally well-tolerated and results in potent B-cell
        depletion when given as a subcutaneous dose and with a day-of-treatment
        oral steroid regimen. SBI-087 is being developed in collaboration with
        Pfizer. Studies are ongoing and data will be submitted for presentation
        at future medical congresses.
    --  Lastly, Trubion announced Pfizer's decision to discontinue development
        of TRU-015 (PF-05212374), an investigational drug in Phase 2 evaluation
        for the treatment of rheumatoid arthritis (RA) developed under the
        companies' CD20 collaboration. However, Pfizer also confirmed that it
        will continue to develop SBI-087 (PF-05230895), Trubion's
        next-generation, humanized, subcutaneous CD20 RA product candidate also
        in Phase 2 clinical evaluation.

2010 Outlook

Trubion has revised its 2010 guidance based on a change in timing of the anticipated milestone of $6 million from Abbott for the initiation of the Phase 2 portion of the TRU-016 study in chronic lymphocytic leukemia (CLL) patients, as well as changes to its CD20 partnership with Pfizer.

Achievement of the Abbott milestone is now expected during the first half of 2011 as a result of protocol modifications that are designed to optimize the dose level and regimen. The maximum tolerated dose has not been reached.

In addition, Trubion has decreased its anticipated annual operating cash requirements from $33 million-$38 million to $29 million-$34 million. The revised guidance, which does not include any additional cash receipts associated with potential new partnerships, is as follows:

    --  Trubion anticipates 2010 revenues to be approximately $19 million to $24
        million earned through the company's Pfizer and Abbott collaborations.
    --  Operating cash requirements in 2010 are expected to be approximately $29
        million to $34 million.

Based on its current forecast, and excluding any proceeds from potential new partnerships or financings, Trubion expects that its existing capital resources will support the company's operations into the second half of 2011.
