Gainers

Sangamo Biosciences Inc. (SGMO) stock gained 5 percent to $6.30 in the pre-market trading. The company said data from its Phase 1 clinical programs to develop SB-728-T, a novel therapeutic approach for the treatment of HIV/AIDS, were discussed in two presentations. The company said in an oral presentation made on Sept. 17 that data were presented from all dosing cohorts of Sangamo's Phase 1 dose escalation study SB-728-902 in subjects on highly active antiretroviral therapy or HAART who entered the study with CD4+ T-cells counts of <500 cells/mm3 after several years of therapy.

A presentation made on Sept. 18 described data from the second cohort of a Phase 1 clinical study of the same drug, conducted at the University of Pennsylvania and Albert Einstein College of Medicine, in subjects who entered the study with CD4+ T-cell counts of >450 cells/mm3 and underwent a treatment interruption or TI of HAART following treatment with SB-728-T. The company said SB-728-T is generated by ZFN-mediated modification of the gene encoding the CCR5 receptor in a patient's own T-cells. ZFN modification disrupts the expression of this key co-receptor for HIV entry and renders cells resistant to HIV infection.

Identive Group, Inc. (INVE) stock increased 3.54 percent to $2.05 in the pre-market trading. The company said it will be demonstrating the market's first NFC tag based on NXP Semiconductor's new NTAG203 chip at the NFC World Congress exhibition in France this week. Identive's new Smartag NFC product is available in poster label, pairing tag or tag-in-box form factors and offers an ideal combination of memory size and read range to enable NFC applications through glass windows, display cases and the like.

Advanced Analogic Technologies, Inc. (AATI) stock rose 1.71 percent to $4.75 in the pre-market trading. The company announced developments relating to its pending acquisition by Skyworks Solutions Inc. As detailed in the S-4 filing made by Skyworks on Sept. 9, two meetings were scheduled in an effort to resolve the matters in dispute between the two companies relating to requested business and financial information, and access to an AnalogicTech officer. These meetings took place on Sept. 13 and Sept. 15, respectively. While AnalogicTech believes it had never been in breach of any of its obligations under the merger agreement, to the extent Skyworks asserted there was a breach of the merger agreement, the company believes any such claimed breach was cured by its actions in conjunction with these meetings. The company said it cannot provide further commentary beyond the information that is in the SEC filings and will continue to keep investors updated through appropriate disclosures.
