Protalex, Inc. To Present Phase 1b PRTX-100 Data At The 2012 American College of Rheumatology Annual Meeting

The Staphylococcal Protein A based PRTX-100 drug administered to patients with Active Rheumatoid Arthritis

SUMMIT, N.J., Oct. 18, 2012 /PRNewswire/ -- Protalex, Inc. (OTCBB: PRTX), a clinical stage biopharmaceutical company, today announced that its abstract on results from the recently completed PRTX-100 Phase 1b randomized, multiple-dose, dose-escalation study in South Africa of PRTX-100 has been accepted for oral presentation at the American College of Rheumatology (ACR) 2012 Annual Meeting to be held in Washington D.C. November 9-14. Protalex is focused on the development of a class of drugs designed to treat autoimmune and inflammatory diseases including rheumatoid arthritis (RA),

The abstract entitled "A Phase 1, Randomized, Double-Blind, Placebo-Controlled Multiple-Dose Study of Intravenous Staphylococcal Protein A in Patients with Active Rheumatoid Arthritis On Methotrexate: Safety, Pharmacokinetics and Efficacy" will be presented by Protalex's Chief Scientist and lead author Dr. Edward Bernton on Sunday, November 11th at 5:00 pm in Ballroom A of the Washington Convention Center.

The study of PRTX-100, a proprietary form of purified Staphylococcal protein A, was conducted in South Africa on 37 adult patients with active RA and demonstrated that the drug was generally safe and well-tolerated at all dose levels. More patients in the higher dose cohorts showed improvement in their CDAI (Clinical Disease Activity Index for RA) than did patients at the lower dose or placebo cohorts.

About Protalex, Inc.

Protalex, Inc. is a clinical stage biopharmaceutical company focused on the development of a class of biopharmaceutical drugs for treating autoimmune and inflammatory diseases, including but not limited to, rheumatoid arthritis. Protalex's lead product, PRTX-100, is formulated with a highly purified form of Staphylococcal protein A, and has completed a Phase 1b clinical trial on adult patients with active rheumatoid arthritis in South Africa. The study was designed to evaluate and assess, among other things, its safety and tolerability. PRTX-100 has the ability, at very low concentrations, to bind to and to regulate activation of human B-lymphocytes and macrophages, which mediate inflammation in certain autoimmune diseases.  Laboratory studies indicate that the mechanism involves interaction with specific intracellular signaling pathways.  Pre-clinical studies also demonstrate that very low doses of PRTX-100 have potent therapeutic effects in certain models of immune-mediated inflammatory diseases.

Protalex is planning to further study the safety and treatment effect of PRTX-100 at higher dose levels with a new clinical trial expected to commence in the U.S. by December 2012.
