Opexa Therapeutics Reports First Quarter 2011 Financial Results

THE WOODLANDS, Texas--(BUSINESS WIRE)--May 6, 2011--Opexa Therapeutics, Inc. (NASDAQ: OPXA), a company developing Tovaxin®, a novel T-cell therapy for multiple sclerosis (MS), today reported financial results for the quarter ended March 31, 2011 and provided an update on its corporate developments.

Recent highlights include:

• Closing an underwritten public offering of $8.5 million gross proceeds, providing necessary funding to continue preparations for a planned Phase III clinical trial;
• Presenting clinical data on Tovaxin during a poster session at the 63^rd annual American Academy of Neurology (AAN) conference, highlighting important efficacy data in a subpopulation of patients that had previously not been exposed to or taken any drugs for the treatment of their MS; and
• Presenting Opexa’s progress in the ongoing clinical development program for Tovaxin at the 13^th annual BIO CEO & Investor Conference in New York and the 6^th annual Cell Therapy Conference in Beijing.

“We have maintained an active pace over the past several months in preparation for our Phase III clinical trial and are making good progress on a number of fronts,” commented Neil K. Warma, President and Chief Executive Officer of Opexa. “We are using the proceeds from our recent financing to ramp up our efforts in preparation for the trial. The funds will be directed, in part, over the next several months to increasing our headcount to an appropriate level to manage future studies and executing necessary manufacturing and clinical steps in advance of initiating the trial. The presentation of the efficacy data was well received at AAN, and after reviewing recent data from other MS developmental drugs, we continue to believe Tovaxin is very well positioned to be a leading therapy in the treatment of MS. Tovaxin’s potent efficacy and excellent safety profile, coupled with the fact that Tovaxin is newly manufactured each year to match each patient’s evolving disease profile, is generating strong interest among patients and physicians.”

“As of the end of the first quarter, March 31, 2011, our cash and cash equivalents totaled approximately $11.4 million and our monthly burn rate for the quarter was approximately $425,000. At the current burn rate, we should have sufficient capital beyond 2011, and we are focused on raising the necessary funds to commence our planned Phase III clinical trial either through a potential Tovaxin partnership or additional capital raise,” commented Mr. Warma.

First Quarter Financial Results

Opexa reported no commercial revenues in the three months ended March 31, 2011 or in the comparable prior-year period.

Research and development expenses were $685,161 for the three months ended March 31, 2011, compared with $783,534 for the three months ended March 31, 2010. The decrease in expenses was primarily related to a decrease in the engagement of consultants, a decrease in the procurement and use of supplies in our laboratory, a reduction of stock compensation expense, and the reduction of employee recruitment expenses, and was partially offset by an increase in headcount in preparation for increased development activities.

General and administrative expenses for the three months ended March 31, 2011 were $592,058 compared with $484,425 for the three months ended March 31, 2010. The increase in expenses is due to an increase in stock compensation expense to employees and an increase in business development activities, and was partially offset by a decrease in legal expenses.

Opexa reported a net loss for the three months ended March 31, 2011 of $1,307,777, or ($0.06) per share, compared with a net loss for the three months ended March 31, 2010 of $1,422,495, or ($0.09) per share.

Cash, cash equivalents and investments in marketable securities were $11,427,985 as of March 31, 2011 compared to $7,092,036 as of March 31, 2010.

About Opexa

Opexa Therapeutics, Inc. is dedicated to the development of patient-specific cellular therapies for the treatment of autoimmune diseases. The Company’s leading therapy, Tovaxin®, is a personalized cellular immunotherapy treatment that is in late stage clinical development for MS. Tovaxin is derived from T-cells isolated from peripheral blood, expanded ex vivo, and reintroduced into the patients via subcutaneous injections. This process triggers a potent immune response against specific subsets of autoreactive T-cells known to attack myelin and, thereby, reduces the risk of relapse over time.

Opexa is preparing for Phase III clinical trials with Tovaxin following the completion of a Phase IIb clinical study in 150 patients with MS. Data from this clinical study show evidence that relapsing-remitting MS patients treated with Tovaxin saw overall clinical and disability benefits over the placebo group, including a clinically relevant decrease in the Annualized Relapse Rate (ARR), and improvement in disability score (EDSS), as well as an excellent safety profile with no serious adverse events related to Tovaxin treatment.
