Revenues for the second quarter ended June 30, 2018 were $21.4 million, compared to $8.3 million for the same period in 2017. The increase in revenues was primarily related to the collaborations and licensing agreements with Pfizer, for hemophilia A, and Kite, a Gilead company, for gene-edited cell therapies for oncology. Second quarter 2018 revenues were primarily generated from Sangamo's collaboration agreements with Kite, Pfizer and Bioverativ, a Sanofi company.

Research and development expenses were $29.3 million for the second quarter ended June 30, 2018, compared to $15.0 million for the same period in 2017. The increase was primarily due to clinical and manufacturing expenses in support of current clinical studies and investment in dedicated manufacturing capacity. General and administrative expenses were $11.3 million for the second quarter ended June 30, 2018, compared to $6.0 million for the same period in 2017.

Forward-Looking Statements
This press release contains forward-looking statements regarding Sangamo's current expectations. These forward-looking statements include, without limitation, the expectation of the acquisition by Sangamo of TxCell, the anticipated timing and benefits thereof; Sangamo's belief of the potential of CAR-Treg therapies to treat immunological diseases; the planned September 5th SSIEM presentation of preliminary data from the CHAMPIONS Study evaluating SB-913, our in vivo genome editing candidate for MPS II, and the year-end financial guidance provided related to cash, cash equivalents, marketable securities and interest receivable. These statements are not guarantees of future performance and are subject to certain risks, uncertainties and assumptions that are difficult to predict. Factors that could cause actual results to differ include, but are not limited to, the dependence on the success of clinical trials of lead programs, the lengthy and uncertain regulatory approval process, uncertainties related to the initiation and completion of clinical trials, including the Alta study, the fact that the preliminary observations from the Alta study are based on preliminary data from only the first five patients in the study and that these preliminary data may not be representative of final results after all patients are treated in the study and all data are collected and analyzed; whether the final results from the Alta study will validate and support the safety and efficacy of SB-525, Sangamo's reliance on partners and other third-parties to meet their clinical and manufacturing obligations, and the ability to maintain strategic partnerships. Further, there can be no assurance that the necessary regulatory approvals will be obtained or that Sangamo and its partners will be able to develop commercially viable product candidates. Actual results may differ from those projected in forward-looking statements due to risks and uncertainties that exist in Sangamo's operations and business environments. These risks and uncertainties are described more fully in Sangamo's Quarterly Report on Form 10-Q for the quarter ended March 31, 2018 as filed with the Securities and Exchange Commission. Forward-looking statements contained in this announcement are made as of this date, and Sangamo undertakes no duty to update such information except as required under applicable law.
