RICHMOND, Calif., April 26, 2011 /PRNewswire/ -- Sangamo BioSciences, Inc. (Nasdaq: SGMO) today reported first quarter 2011 financial results and accomplishments.

For the first quarter ended March 31, 2011, Sangamo reported a consolidated net loss of $9.6 million, or $0.21 per share, compared to a net loss of $4.0 million, or $0.09 per share, for the same period in 2010. As of March 31, 2011, the company had cash, cash equivalents and marketable securities of $49.2 million.

Revenues for the first quarter of 2011 were $2.2 million, compared to $6.6 million for the same period in 2010. First quarter 2011 revenues were from the company's collaboration agreements with Sigma-Aldrich Corporation and Dow AgroSciences, enabling technology agreements and research grants. The revenue recognized for the first quarter of 2011 consisted of $1.5 million in collaboration and enabling technology agreements and $713,000 in research grants.

The increase in the net loss and decrease in collaboration agreement revenues were primarily due to the completion in July 2010 of the amortization period of revenues related to the commercial license fee received from Sigma under the expanded agreement of October 2009.

Research and development expenses were $8.3 million for the first quarter of 2011, compared to $7.4 million for the same period in 2010. The increase in research and development expenses was primarily due to increased expenses related to our clinical trials of SB-509 for diabetic neuropathy and SB-728-T for HIV/AIDS. General and administrative expenses were $3.5 million for the first quarter of 2011, compared to $3.3 million for the same period in 2010.

Total operating expenses for the first quarter of 2011 were $11.8 million, compared to $10.7 million for the same period in 2010.

Updated Financial Guidance

On April 13, 2011, Sangamo completed an underwritten public offering of 6.7 million shares of its common stock, which resulted in net proceeds of $50.2 million to the company. As a result of this financing, Sangamo is updating its year-end cash guidance and now expects to have cash, cash equivalents and marketable securities in the range of $85 to $90 million at the end of 2011, exclusive of new funding from potential future partnerships.

The company reiterates its earlier guidance relating to operating expenses for 2011, which it expects to be relatively flat compared to 2010, in the range of $43 to $47 million. In addition, under its existing agreements, Sangamo expects revenues, and related cash proceeds, in the range of $10 to $12 million in 2011.

Recent Highlights

• Completion of Enrollment of Sangamo's Phase 2b Clinical Trial in Diabetic Neuropathy. In January 2011, the company announced that enrollment of its Phase 2b double-blind, placebo-controlled clinical trial (SB-509-901) in subjects with diabetic neuropathy (DN) was complete.  Sangamo expects to have top-line efficacy data from this study in the second half of 2011.
• Presentation of Positive Clinical Data from Sangamo's Novel ZFN Therapeutic® Approach for the Treatment of HIV/AIDs at the Conference for Retroviral and Opportunistic Infections (CROI). Positive preliminary clinical data from Phase 1 trials of the company's HIV program were presented at CROI.  The study is designed to evaluate safety and clinical outcomes of Sangamo's zinc finger nuclease (ZFN)-generated CCR5-modified, autologous T-cell product (SB-728-T) for the treatment of HIV/AIDS. CCR5 is the major co-receptor used by HIV to infect cells of the immune system. Data from Sangamo's preclinical programs in HIV/AIDS were also presented at the conference.
• Collaboration with the CHDI Foundation, Inc. (CHDI) to Develop a Novel ZFP Therapeutic for Huntington's Disease (HD). CHDI, a not-for-profit, scientific research organization dedicated to discovering and developing therapies that slow the progression of HD, is providing $1.2 million of funding for the project which uses Sangamo's proprietary zinc finger DNA-binding protein (ZFP) technology.  The novel therapeutic approach will target the huntingtin gene that causes HD, an inherited neurodegenerative disease for which there are currently no therapies available to slow disease progression.
• Completion of an Underwritten Public Offering. On April 13, 2011, Sangamo closed an underwritten public offering of 6.7 million shares of its common stock, resulting in net proceeds of approximately $50.2 million to the company.

About Sangamo

Sangamo BioSciences, Inc. is focused on research and development of novel DNA-binding proteins for therapeutic gene regulation and modification. The most advanced ZFP Therapeutic® development program is currently in a Phase 2b clinical trial for evaluation of safety and clinical effect in patients with diabetic neuropathy. Sangamo also has a Phase 1/2 clinical trial and two ongoing Phase 1 clinical trials to evaluate safety and clinical effect of a treatment for HIV/AIDS as well as a Phase 1 trial of a treatment for recurrent glioblastoma multiforme. Other therapeutic development programs are focused on Parkinson's disease, monogenic diseases, neuropathic pain and nerve regeneration. Sangamo's core competencies enable the engineering of a class of DNA-binding proteins called zinc finger DNA-binding proteins (ZFPs). By engineering ZFPs that recognize a specific DNA sequence Sangamo has created ZFP transcription factors (ZFP TFs) that can control gene expression and, consequently, cell function. Sangamo is also developing sequence-specific ZFP Nucleases (ZFNs) for gene modification. Sangamo has established strategic partnerships with companies in non-therapeutic applications of its technology including Dow AgroSciences and Sigma-Aldrich Corporation.
