Robbins Umeda LLP has commenced an investigation into possible breaches of fiduciary duty and other violations of the law by certain officers and directors at XenoPort, Inc. XenoPort is a biopharmaceutical company that focuses on developing internally discovered product candidates that utilize the body's natural nutrient transport mechanisms to enhance the therapeutic benefits of drugs. The Company was founded in 1999 and is based in Santa Clara, California.

Robbins Umeda LLP's investigation concerns whether the Company's directors and officers caused the Company to make materially false and misleading representations regarding XenoPort's Phase 3 clinical program for an extended-release tablet and development stage drug called Horizant, also known as XP13512 ("512"). Specifically, Robbins Umeda LLP is investigating whether the Company's fiduciaries caused XenoPort to mislead investors about 512, a potential treatment for moderate-to-severe primary Restless Legs Syndrome, including misleading the public about 512's safety.

On February 17, 2010, the Company publicly disclosed that the U.S. Food and Drug Administration had declined to approve 512, with concerns about laboratory results showing pancreatic cell tumors in rats as a result of the use of the drug. Upon this news, XenoPort's stock fell $12.93 per share to close at $6.67 per share on February 18, 2010 -- a one-day decline of 66%.

If you are a shareholder of XenoPort, plan to continue to hold your shares, and would like more information about your rights as a shareholder, please contact attorney Gregory E. Del Gaizo at 800-350-6003 or by e-mail at info@robbinsumeda.com.

Goldfarb Branham LLP is still pursuing potential shareholder claims against the Board of Directors of Texas-based AmeriCredit due to an allegedly unfair buyout by General Motors for $24.40 per share. The Dallas-Fort Worth firm plans to file a stockholder class action lawsuit against the Board of Directors that seeks to make the deal fair for AmeriCredit shareholders. Any AmeriCredit stockholders interested in joining the lawsuit as a plaintiff are encouraged to contact shareholder lawyer Hamilton Lindley at 877-583-2855 or hlindley@goldfarbbranham.com.

"Because at least one analyst has a target price for AmeriCredit of $26.00 per share, and the stock has traded as high as $26.49 per share within the last year, this deal appears unfair for ACF shareholders," said Hamilton Lindley, a shareholder lawyer at Goldfarb Branham. "It is estimated that GM will increase its sales by 10-20 percent with this takeover, but AmeriCredit shareholders will be completely cashed out for a mere $24.40 per share."

Goldfarb Branham LLP firm has significant experience in Texas merger cases and provides nimble, creative, and effective counsel at all stages of litigation. If you own AmeriCredit stock or have information and wish to discuss this matter, contact attorney Hamilton Lindley at 877-583-2855 or hlindley@goldfarbbranham.com. All litigation related expenses are paid for by the firm. The firm only gets paid when it is successful in obtaining a benefit for the shareholders.
