Ligand Partner GlaxoSmithKline Gains FDA Breakthrough Therapy Designation for Promacta®/Revolade® for Severe Aplastic Anemia

Ligand Partner GlaxoSmithKline Gains FDA Breakthrough Therapy Designation for Promacta®/Revolade® for Severe Aplastic Anemia Download as PDF February 03, 2014 SAN DIEGO-- Ligand Pharmaceuticals Incorporated (NASDAQ:LGND) today announced that the U.S. Food and Drug Administration (FDA) has granted its partner GlaxoSmithKline plc (LSE:GSK) Breakthrough Therapy designation for Promacta®/Revolade® (eltrombopag) for the treatment of cytopenias in patients with severe aplastic anemia (SAA) who have had insufficient response to immunosuppressive therapy. “Promacta continues to be the basis of ground breaking and promising science in important areas with significant unmet medical needs” said John Higgins, President and CEO of Ligand. “We congratulate the global Promacta/Revolade development team at GSK, and commend them for their continued scientific and regulatory progress.” SAA is a rare disorder in which the bone marrow fails to make enough new blood cells. There are no approved therapies available for SAA patients who are unresponsive to initial immunosuppressive therapy (IST). Of those patients unresponsive to initial IST, approximately 40% die from infection or bleeding within five years of their diagnosis.i The Breakthrough Therapy designation was based on the results from an open-label, Phase II National Institute of Health (NIH) study (09-H-0154) of eltrombopag in 43 heavily pre-treated SAA patients with an insufficient response to IST. About Breakthrough Therapy Designation The Breakthrough Therapy designation was enacted as part of the 2012 FDA Safety and Innovation Act (FDASIA) and is intended to expedite development and review of drugs to treat serious or life-threatening medical conditions when preliminary clinical evidence demonstrates that the drug may have substantial improvement on at least one clinically significant endpoint over available therapies. Breakthrough Therapy designation includes all the features of the Fast Track designation, as well as more intensive guidance from the FDA on a drug’s clinical development program.ii About Promacta For full U.S. Prescribing Information and Medication Guide and EU Patient Information Leaflet or Summary of Product Characteristics (SPC) for eltrombopag please visit http://www.gsk.com/products.html.
