THE WOODLANDS, Texas--(BUSINESS WIRE)--Opexa Therapeutics, Inc. (NASDAQ:OPXA), a company dedicated to the development of patient-specific cellular therapies for the treatment of autoimmune diseases such as multiple sclerosis (MS) and diabetes, today announced an update on corporate activities. Since providing additional data analysis for its TERMS Phase IIb clinical trial in October, Opexa has been actively engaged in discussions to partner Tovaxin®, its lead therapy and novel treatment for MS, as it positions itself for pivotal trials and future commercialization. Additionally, partnering discussions have been initiated and are advancing with Opexa’s stem cell therapy to treat Type 1 and Type 2 diabetes.

To further support the ongoing discussions and advance the clinical development of Tovaxin, Dawn McGuire, M.D., a member of Opexa’s Clinical Advisory Board, has agreed to increase her advisory role to the company and guide clinical development of Tovaxin. Dr. McGuire, a board-certified neurologist, has experience in all phases of drug and biologic development for multiple sclerosis. While Vice President of Clinical Research and Medical Affairs at Elan Pharmaceuticals, she was the development team leader for Tysabri.

"Tovaxin offers the potential for immunomodulatory treatment that is exquisitely individualized for a complex disease that manifests in a highly individual manner. Early results with Tovaxin suggest reduction not only in relapse rates but also in global neuronal loss among patients with the most active disease. I see great promise here,” commented Dr. McGuire.

In other management news, Opexa has promoted Donna Rill to Senior Vice President of Operations. She will continue to oversee the production and manufacturing of all cell therapy programs and will focus on the upcoming end of Phase II meeting with the FDA and the scale up of operations to support future Tovaxin trials in North America and Europe. Dr. Jim Williams, Chief Operating Officer, will retire from the company, effective February 13, 2009 after several years of overseeing the clinical development of Tovaxin. He will remain available in a consulting capacity to assist with any transition.

“With possibly the safest therapy for MS demonstrated to date and some very encouraging efficacy data in clinically relevant relapse rates and disability scores, we are pleased with the level of discussions we are having with potential partners,” commented Neil K. Warma, President and CEO of Opexa Therapeutics, Inc. “We are extremely fortunate to have someone of Dr. McGuire’s experience to further advise on our clinical development strategy and steward the clinical development of Tovaxin. Her substantial knowledge and experience in MS, having overseen the early development of Tysabri will certainly contribute very favorably to our development program and partnering discussions. We are grateful to Jim for having contributed immensely to the development of Tovaxin to date and for overseeing the management of the first-in-class TERMS IIb study and we are pleased he will remain a consultant to the company as we continue forward with our clinical strategy.”

As previously disclosed Opexa streamlined its operations in late November 2008 to better manage its current expenses, reduce its cash burn and extend its available runway. As partnership discussions continue to advance, the company will pursue a number of strategic alternatives including the raising of additional capital to allow it the time to further pursue and negotiate a partnership for Tovaxin in MS and/or its adult stem cell program in diabetes.

Data from the TERMS Phase IIb clinical study with Tovaxin in MS demonstrated the following:

* Promising Efficacy – The Annualized Relapse Rate (ARR) for the prospective group of patients with a greater level of disease burden was 0.28 relapses per patient per year. Remarkably, the ARR for this group dropped to 0.07 after the full course of treatment was administered. Additionally, this group showed a statistically significant improvement in disability (p=0.045) and a substantial improvement in brain atrophy when treated with Tovaxin.
* Excellent Safety - There were no serious adverse events (SAEs) associated with Tovaxin treatment in the TERMS study. This is consistent with the previous clinical trials with Tovaxin, all of which showed no SAEs associated with Tovaxin treatment. This is an especially critical finding given the recent serious side effect occurrences associated with certain marketed and developmental MS products and the ongoing regulatory focus on risk/benefit relationships.
* Ease of Administration - Patient compliance may be improved with Tovaxin’s treatment regimen of five subcutaneous injections per year.
* Epitope data - An analysis of the immunology data collected from several thousand patient samples is yielding valuable information on MS biomarkers and Tovaxin mechanism of action. Tovaxin appears to reduce myelin peptide reactivity and reduce the risk of relapse over time.

About Tovaxin for MS

Tovaxin is an individualized T-cell therapeutic vaccine that consists of attenuated patient-specific myelin-reactive T-cells against peptides of proteins from Myelin basic protein (MBP), Myelin oligodendrocyte glycoprotein (MOG) and Proteolipid protein (PLP) or combinations thereof. Tovaxin’s dual mechanism of action combats the demyelination of the nerve fibers in the central nervous system, the underlying cause of MS. Clinical results have demonstrated that Tovaxin produces the following therapeutic effects:

* Anti-idiotypic effect - Induces an immune response that depletes and regulates the circulating pathogenic myelin-reactive T-cells that attack the myelin sheath of nerve fibers.
* Anti-ergotypic effect - Rebalances the overall immune system by causing a shift from pathogenic inflammatory T-cells to anti-inflammatory T-cells.

Tovaxin is manufactured in Opexa’s in-house cGMP facility.

About the TERMS Study

The TERMS study was a Phase IIb multi-center, randomized, double blind, placebo-controlled trial in 150 patients with Relapsing-Remitting Multiple Sclerosis or high risk Clinically Isolated Syndrome. The study involved 2:1 randomization with 100 patients receiving Tovaxin and 50 receiving placebo. According to the study protocol, patients received a total of five subcutaneous injections at weeks 0, 4, 8, 12 and 24. The primary efficacy endpoint of the TERMS trial was the cumulative number of gadolinium-enhanced brain lesions (CELs) using MRI scans summed over weeks 28, 36, 44 and 52. The trial’s secondary efficacy endpoints included annualized relapse rate (ARR), new CELs at weeks 28 through 52 and T2-weighted lesion volume compared to baseline.

About Opexa’s Stem Cell program for diabetes

The autologous adult stem cell research platform at Opexa Therapeutics has been focused on the development of monocyte derived stem cells (MDSC) which are converted to monocyte derived pancreatic-like islets (MDI) as a potential therapeutic transplantation product for the treatment of Type 1 and Type 2 diabetes. A proprietary in vitro process has been developed to derive MDSC from blood monocytes, expand them ex vivo, and then convert them to MDI for transplantation into the hepatic main portal vein of diabetic patients. Opexa has demonstrated that the MDSC are multipotent stem cells that may be cultured under defined conditions to convert them into several cellular lineages. The MDSCs have specific time-dependent expression of markers that distinguish them from other stem cells. MDSCs have the capacity to differentiate towards hematopoietic, epithelial, endothelial, endocrine and neuronal cells. Currently, Opexa’s main focus is the development of MDSC technology as a platform for the ex vivo generation of MDI for potential application in autologous transplantation cell therapy for diabetes mellitus patients.

Now if I can just get someone to answer the * phone in TX, I could inform them about what's going on here with Cheryl and me and kindly suggest they get THE PATIENTS informed and involved in this loop, too.

It's not going to do anyone any good if one of us lab rats, who would gladly jump into the program again, opts for something else and gets him/herself disqualified in the process!

At least a "try to hold on and we'll put you on speed dial to let you know when we're revving up again."

Looks from that report that they're just about ready to jump into the vaccine program for diabetes, too, doesn't it?

Note to Gang: please forward me the name of your coordinators so I can more finely tune the mail I'm prepping. So far, I've only heard from Cheryl... and I kinda think there are more than just TWO of us interested in cracking the whip around here... 8O

I read this as a press release that's fishing for investors more than a sign that they have anything at all concrete on the way. If they did, my hunch is they would have kept quiet until it finalized.

Hope I'm wrong.

You are right, thanks Jane.

A couple of weeks ago I got the bright idea of getting rid of a few files I don't use and in the process got my computer to the point that it wouldn't boot up and had to re-load windows. I don't think I lost everything from the last 3 or 4 years but I do have to figure out how to access it all from "windows.old"

In the meantime I'll try to find the contact info from the trial paperwork.

I've been ready to commit Window-cide, too. I thought I had a bad mouse but it turned out to be a major system problem. I canNOT afford to lose files--and e-mail; this is what happens when the beasts take over our lives! (Heretical Note: I'm beginning to think that gobbledeegoop in the Book of Revelation about "mark of the beast" is that thrice-damned Windows logo...) :wink:

My two geeks (hubbie and nephew) murdered my machine this past weekend and blew out its brains--purged the hard drive and the software system and re-installed everything. So far, everything's running smoothly but I still have to dowload AIM and Yahoo Messenger and something audio. Too much YouTube to do without sound!

Somewhere in my heretical and blasphemous files, I have this cute little cartoon of the Lord sitting at a computer console, smiling. After all, "Jesus Saves," you know. :lol:
