AUSTIN, Texas, Oct. 1, 2015 (GLOBE NEWSWIRE) — XBiotech (NASDAQ:XBIT), the world’s leading developer of next-generation True Human™ therapeutic antibodies, announced today that the U.S. Food and Drug Administration (FDA) has granted Fast Track Designation for its novel True Human monoclonal antibody therapy intended to treat all forms of Staphylococcus aureus infections, including Methicillin-resistant S. aureus (MRSA).

XBiotech’s antibody therapy, known as 514G3, is currently being evaluated in a Phase 1/2 clinical study and was developed from a human donor with natural antibodies effective at neutralizing MRSA and non-MRSA forms of S. aureus. 514G3 knocks out the principle immune evasion mechanism of the bacteria, allowing white blood cells to detect and destroy the bacteria. 514G3 is expected to treat all strains of MRSA and can be used without consideration for strain-specific resistance to various antibiotics. As a True Human monoclonal antibody, 514G3 is expected to be well tolerated without the side effects or risks of antibiotics.

John Simard, the Company’s Chief Executive Officer, said, “Receiving FDA Fast Track Designation highlights the importance for this product candidate to treat life-threatening bacterial infections. We look forward to reporting on further developments as this important program continues to generate clinical findings.”

About XBiotech

XBiotech is pioneering the discovery and development of targeted antibodies based on its True Human™ technology. The company’s mission is to rethink the way antibody medicines are discovered and commercialized by advancing its robust pipeline of human antibodies for treating serious diseases such as cancer, inflammatory conditions and infectious diseases. XBiotech’s lead product, Xilonix™, is a potential breakthrough antibody therapy that is currently the subject of two pivotal clinical studies for treating patients with advanced colorectal cancer. Xilonix specifically targets and neutralizes interleukin-1 alpha (IL-1a), a molecule known to promote angiogenesis, growth and spread of tumors, as well as mediate symptoms such as metabolic dysregulation, fatigue and anxiety associated with advanced cancer. XBiotech’s True Human antibodies are cloned directly from individual donors who possess natural immunity against certain diseases. For more information, visit www.xbiotech.com.
