Opexa Therapeutics Presents Tovaxin Phase I/II Data at the American Academy of Neurology 60th Annual Meeting
THE WOODLANDS, Texas — Opexa Therapeutics, Inc. (NASDAQ:OPXA), a company involved in the development and commercialization of cell therapies, today announced that Brian Loftus, M.D., of Bellaire Neurology and the Principal Investigator of the Tovaxin Phase I/II studies, presented data titled "Autologous Attenuated T-Cell Vaccine (Tovaxin(R)) Dose Escalation in Multiple Sclerosis Relapse-Remitting and Secondary Progressive Patients Nonresponsive to Approved Immunomodulatory Therapies" at the American Academy of Neurology meeting today. The AAN meeting is taking place at the McCormick Place West Convention Center in Chicago, IL.
The objective of the Tovaxin Phase I/II dose escalation study was to assess the safety and effectiveness of T cell vaccine (Tovaxin(R)) in MS patients non-responsive to approved immunomodulatory therapies. The trial results indicate statistically significant improvements from baseline observed using the annualized relapse rate and myelin-reactive T-cell count effectiveness measurements.
"The positive therapeutic effects of safety, early effectiveness and tolerability observed in this study suggest that depletion of myelin-reactive T-cells using Tovaxin, a trivalent T-cell vaccine, may be an appropriate treatment strategy for patients with MS and warrants further study," said Dr. Loftus.
About T-cell Vaccination
For a T-cell vaccine to be effective, it should be able to induce T-cell cytotoxic and/or regulatory immune responses against the pathogenic T-cells. Studies of T-cell vaccine have indicated that T-cell vaccination with peripheral blood-derived autologous myelin-peptide selected T-cells in multiple sclerosis patients resulted in the in vivo induction of CD8+ cytotoxic T-cells and CD4+CD25+FoxP3 Tregs specific for T-cell vaccine. The induction of anti-idiotypic cytotoxic CD8+ effector T-cells and anti-ergotypic CD4+CD25+FoxP3 positive Tregs is believed to provide a therapeutically effective dual mechanism of protection to patients treated with Tovaxin. The observed regulatory immune responses have been shown to collectively correlate with clinical improvement in some patients treated in earlier clinical studies.
