Opexa Therapeutics, Inc. has completed an internal assessment of data from its Phase I/II two year extension study with Tovaxin in patients with MS. While confirming the favorable safety and efficacy profile of Tovaxin, further analysis also confirms both the benefit of consecutive annual treatments with Tovaxin and the advantage of tailoring each vaccination to the patient's changing disease profile. The extension study evaluated 22 intent-to-treat patients that had enrolled in two Phase I/II open-label clinical studies with Tovaxin. 13 patients were enrolled with Relapse Remitting Multiple Sclerosis (RRMS) and 9 with Secondary Progressive Multiple Sclerosis (SPMS). After the first annual course of treatment the company conducted an analysis of each patient's specific disease profile and myelin peptide epitope profile using Opexa's proprietary Epitope Analysis Assay (EAA). The analysis showed that 19 of the 22 patients (86%) had undergone an epitope shift, or change in disease pattern since the original course of treatment. Based on the epitope analysis, Opexa manufactured a new and specific vaccine for each of these patients for their second course of treatment. This enabled Opexa to tailor each vaccine to the individual's current disease profile, thereby maximizing the effect................
