Trubion Pharmaceuticals, Inc. Reports First-Quarter 2010 Financial Results

SEATTLE, May 6, 2010—Trubion Pharmaceuticals, Inc. (NASDAQ: TRBN) today announced financial results for its first-quarter ended March 31, 2010.

First-Quarter 2010 Financial Results

Revenue for the first quarter of 2010 was $5.5 million compared with $4.2 million for the first quarter of 2009. Revenue was primarily earned through Trubion’s strategic collaborations with Pfizer for the development of CD20-directed candidates, including TRU-015 and SBI-087 and Facet Biotech, for the development of CD37-directed targets, including TRU-016.

During the first quarter of 2010, Trubion recognized $1.8 million in revenue from its Facet collaboration. The $1.8 million is comprised of $0.6 million for recognition of the $20 million upfront fee and $1.4 million equity premium and $1.2 million for collaborative research funding.

The increase in revenue related to the Facet collaboration was partially offset by lower revenue recognized from Trubion’s collaboration with Pfizer. The decrease in revenue was related to the amount of reimbursable legal fees. Revenue from the Pfizer collaboration for the three months ended March 31, 2010 was comprised of $2.6 million for collaborative research funding and $1.2 million for recognition of the $40 million upfront fee compared to $3.0 million for collaborative research funding and $1.2 million for recognition of the $40 million upfront fee in Q1 2009.

Total operating expenses for the first quarter of 2010 were $11.5 million compared with $15.2 million for the first quarter of 2009. The decrease in operating expenses was primarily due to lower outside manufacturing costs related to TRU-016, and lower personnel and non-cash stock-based compensation expenses due to the restructuring in 2009 and the resignation of Trubion’s chief executive officer in November 2009.

Net loss for the first quarter of 2010 was $6.1 million, or $0.30 per diluted common share, compared with a net loss of $11.0 million, or $0.61 per diluted common share, for the first quarter of 2009.

Trubion had $46.3 million in cash, cash equivalents and investments as of March 31, 2010, compared with $54.8 million as of Dec. 31, 2009.

“In the first quarter, we continued to advance the development of our product candidates which included Pfizer’s initiation of a Phase 2 clinical trial of SBI-087 in rheumatoid arthritis,” said Steven Gillis, executive chairman, acting president, and chairman of the board of directors at Trubion. “We look forward to sustained momentum in the second quarter as we partner with Facet, now a wholly owned subsidiary of Abbott Laboratories, to execute on a robust clinical development plan for TRU-016 and we present clinical data updates on several of our product candidates at scientific congresses.”

Recent Milestones

• In January 2010, Trubion’s partner, Pfizer, initiated a Phase 2 clinical trial of SBI-087 (PF-05230895) for the treatment of RA. SBI-087 is a next-generation, humanized Small Modular ImmunoPharmaceutical (SMIP^TM) protein therapeutic directed against the CD20 antigen. SBI-087 is also being evaluated in a Phase 1 clinical trial for systemic lupus erythematosus (SLE).

• In April, Abbott announced it completed its acquisition of Facet, which will now operate as a wholly owned subsidiary of Abbott. Abbott has informed Trubion that it remains interested in TRU-016 and intends to proceed with its development.

2010 Outlook

Trubion has revised its 2010 guidance based on a change in timing of the anticipated milestone of $6 million from Facet for the initiation of the Phase 2 portion of the TRU-016 study in CLL patients. This milestone is now currently expected to be achieved in 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. As a result, Trubion has increased its anticipated annual operating cash requirements from $27-$32 million to $33-$38 million and lowered its anticipated revenues from $25-$30 million to $19-$24 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-$24 million earned through the company’s Pfizer and Facet collaborations.

• Operating cash requirements in 2010 are expected to be approximately $33 million-$38 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.
