Gainers

Oncothyreon Inc (ONTY) stock jumped 10.74 percent to $4.95 in the pre-market trading. Loss for the first quarter widened to $7.1 million or $0.24 per share from $0.8 million or $0.03 per share last year. Results included a non-cash expense of $1.5 million as a result of an increase in fair value of warrant liability versus $4.6 million decrease in fair value of warrant liability in the year-ago quarter. Revenue grew to $145,000 from $5,000. Analysts had expected a loss of $0.18 per share on revenue of $2 million.

For the full year 2011, the company expects expenses to be higher when compared to 2010, primarily as a result of the more advanced clinical development of PX-866 and IND-enabling development activities for ONT-10. Oncothyreon currently sees cash used in operations in 2011 to be about $23 million. As a result, the company predicts that its existing cash will be sufficient to fund operations for at least the next 12 months.

Affymetrix Inc. (AFFX) stock climbed 7.23 percent to $6.60 in the pre-market trading. The company said the U.S. Food and Drug Administration has cleared the addition of new gene expression reagents as accessories to its GeneChip Microarray Instrument System for in vitro diagnostic use, making Affymetrix the first in the industry to provide a comprehensive microarray-based clinical toolkit for diagnostic test development, signature discovery for companion diagnostics, and translational initiatives.

According to the company, Affymetrix Gene Profiling Reagents offer unparalleled convenience by simplifying assay workflow, decreasing hands-on time, and reducing quality control testing compared to research-use-only-produced products. Use of the Gene Profiling Reagents for clinical diagnostic test development should lead to more consistent results and lower commercialization costs for clinical providers and other Affymetrix customers.

USA Technologies Inc. (USAT) stock grew 7.02 percent to $2.59 in the pre-market trading.

BroadSoft, Inc. (BSFT) stock gained 6.18 percent to $45.85 in the pre-market trading. The company expects second quarter adjusted earnings of $0.09 to $0.11 per share and revenue of $28 million to $29 million, while Street predicts profit of $0.09 per share on revenue of $27.21 million. For the full year 2011, the company raised its adjusted earnings guidance to range of $0.67 to $0.77 per share from previous forecast of $0.56 to $0.66 per share.

The company said the second quarter and full year guidance does not reflect the impact of a potential release of a tax valuation allowance relating to net deferred tax assets. The company currently expects this release could occur as early as the second quarter of 2011 and the release of the valuation allowance would be recorded as an income tax benefit, which would significantly increase the company's reported net income for the period in which the release occurs.

BroadSoft reported first quarter adjusted earnings of $5.04 million or $0.18 per share, compared to a loss of $2.11 million or $0.11 per share last year.

We are also excited about our Capesaris program. We have met with the FDA and confirmed that the primary endpoint required for approval for Capesaris for first line treatment of advanced prostate cancer will be maintenance of castrate levels of serum total testosterone. We plan to initiate a Phase IIb clinical trial comparing Capesaris to Lupron in advanced prostate cancer patients in the second quarter of 2011. We expect this study to enroll quickly and to have primary efficacy results from this open label study in the fourth quarter of this year, said Steiner.
