SAN DIEGO, Nov. 13, 2013 /PRNewswire/ -- Mast Therapeutics, Inc. (NYSE MKT: MSTX) today announced that the U.S. Food and Drug Administration (FDA) has designated MST-188 for the treatment of acute limb ischemia as an orphan drug.
Brian M. Culley, Chief Executive Officer, said: "This designation represents further progress in our development of MST‑188 as an adjunct therapy for life-threatening conditions treated with existing thrombolytic agents, such as tPA. As we previously reported, we are on track to initiate a phase 2, clinical proof-of-concept study in acute limb ischemia in early 2014. If this study demonstrates that MST-188 improves the 'clot busting' activity of tPA in acute limb ischemia, we believe it would provide the data to design a registrational phase 3 study in that orphan disease, as well as generate data to support development in indications with even larger market opportunities, such as stroke."
