VistaGen Therapeutics, Inc. (“VistaGen” or the “Company”), a biotechnology company focused on using proprietary pluripotent stem cell technology for drug rescue and cell therapy, was incorporated in California on May 26, 1998 (inception date).  Excaliber Enterprises, Ltd. (“Excaliber”) was organized as a Nevada corporation on October 6, 2005. On May 11, 2011, Excaliber acquired all outstanding shares of VistaGen for 6,836,452 shares of Excaliber’s common stock (“Merger”), and assumed VistaGen’s pre-Merger obligations to contingently issue common shares in accordance with stock option agreements, warrant agreements, and a convertible promissory note.  As part of the Merger, Excaliber repurchased 5,064,207 shares of its common stock from two stockholders for a nominal amount, leaving 784,500 shares of common stock outstanding at the date of the Merger.  The 6,836,452 shares issued to VistaGen stockholders in connection with the Merger represented approximately 90% of the outstanding shares of Excaliber’s common stock after the Merger.  As a result of the Merger, the business of VistaGen became the business of Excaliber. After the Merger:
VistaGen, as the accounting acquirer in the Merger, recorded the Merger as the issuance of stock for the net monetary assets of Excaliber, accompanied by a recapitalization.  This accounting for the transaction was identical to that resulting from a reverse acquisition, except that no goodwill or other intangible assets were recorded.  A total of 784,500 shares of common stock, representing the shares held by stockholders of Excaliber immediately prior to the Merger, have been retroactively reflected as outstanding for all periods presented in the accompanying Condensed Consolidated Financial Statements.  Additionally, the accompanying Condensed Consolidated Financial Statements retroactively reflect the authorized capital stock and $0.001 par value of Excaliber’s common stock, and the 2 for 1 forward stock split after the Merger.
Description of VistaGen’s Business
VistaGen is a biotechnology company applying human pluripotent stem cell technology for drug rescue and cell therapy. Drug rescue involves the combination of human pluripotent stem cell technology with modern medicinal chemistry to generate new chemical variants of once promising small molecule drug candidates that pharmaceutical companies have discontinued during preclinical or early clinical development due to heart or liver toxicity, despite positive efficacy data demonstrating their potential therapeutic and commercial benefits. VistaGen plans to use its pluripotent stem cell technology to generate early indications, or predictions, of how humans will ultimately respond to new drug candidates before they are ever tested in humans.  In parallel with its drug rescue activities, VistaGen is funding early-stage nonclinical studies focused on potential cell therapy applications of its Human Clinical Trials in a Test Tube ™ platform.
Early in the first quarter of calendar 2012, VistaGen began a Phase 1b clinical study of AV-101, a small molecule drug candidate for treatment of neuropathic pain. This study includes testing AV-101 in healthy volunteers using the intradermal capsaicin model of neuropathic pain.  This often-used induced neuropathic pain model will test whether AV-101 will reduce the increased pain sensitivity associated with a small injection under the skin of capsaicin, the material found in chili peppers. Neuropathic pain, a serious and chronic condition causing pain after an injury or disease of the peripheral or central nervous system, affects approximately 1.8 million people in the U.S. alone. To date, VistaGen has been awarded over $8.9 million from the U.S. National Institutes of Health (NIH) for development of AV-101. VistaGen plans to initiate Phase 2 clinical studies of AV-101 in the fourth quarter of 2012, subject to receiving additional government or private foundation grant funding and FDA approval.
The Company is in the development stage and, since inception, has devoted substantially all of its time and efforts to stem cell research and stem-cell based bioassay development, small molecule drug development, creating, protecting and patenting intellectual property, recruiting personnel and raising sufficient working capital.
