Protalex, Inc. (OTCQB: PRTX) is a clinical-stage biopharmaceutical company focused on the development of a class of drugs for treating a wide array of autoimmune and inflammatory diseases, including rheumatoid arthritis. Protalex’s lead product, PRTX-100, is derived from bacteria that are known to circumvent aspects of the human immune system. PRTX-100 is a formulation of a proprietary, highly purified form of the Staphylococcal Protein A, which is an immunomodulatory protein produced by Staphylococcus aureus bacteria. PRTX-100 has the ability, at very low concentrations, to bind to human B-lymphocytes and macrophages and to modulate immune processes that mediate inflammation in certain autoimmune diseases. Laboratory studies indicate that the mechanism involves interaction with specific immunologic signaling pathways. Pre-clinical animal studies also demonstrate that very low doses of PRTX-100 have potent therapeutic effects in certain models of immune mediated inflammatory diseases. To date, human clinical studies indicate that PRTX-100 is generally safe and well tolerated at all dose levels evaluated.
