PromactaTreatment for Idiopathic (Immune) Thrombocytopenic Purpura
Update: Promacta Now FDA Approved - November 20, 2008
Ligand Earns $1 Million Milestone Payment as GlaxoSmithKline Submits New Drug Application for Promacta (eltrombopag)
SAN DIEGO--(BUSINESS WIRE)--Dec 20, 2007 - Ligand Pharmaceuticals Incorporated (the Company or Ligand) today announced that it has earned from GlaxoSmithKline (GSK) a milestone payment of $1 million as a result of GSK's submission of a New Drug Application (NDA) for Promacta (eltrombopag). If approved, Promacta would be the first oral platelet growth factor therapy for the short-term treatment of previously treated patients with chronic idiopathic thrombocytopenic purpura (ITP) to increase platelet counts and reduce or prevent bleeding. Chronic ITP is a disorder marked by increased platelet destruction and/or inadequate platelet production in the blood, which causes an increased risk of bruising and bleeding. Promacta is an investigational, once-daily oral treatment that induces the proliferation and differentiation of cells in the bone marrow to produce platelets.
The milestone payment arises from a drug discovery alliance with GSK to focus on the discovery of small-molecule TPO mimetics. Under the terms of the collaboration, Ligand is eligible to receive an additional milestone payment of $2 million upon approval of Promacta by the U.S. Food and Drug Administration (FDA), as well as royalty payments on any future sales of the drug.
"We are very pleased with GSK's progress with Promacta. Their team has done an excellent job executing its clinical activities, and they have obtained encouraging results. This milestone reinforces our belief in Ligand's science and technology that has yielded the first oral TPO receptor agonist," said John L. Higgins, President and Chief Executive Officer of Ligand Pharmaceuticals. "Our collaborations with pharmaceutical industry leaders such as GSK are representative of Ligand's commitment to leverage its technology and research capabilities to create value for shareholders."
Ligand and GlaxoSmithKline Collaboration
The GSK-Ligand collaboration began in 1997 to utilize Ligand's expertise and technology to discover small-molecule drugs to control hematopoieses and treat patients with cancer, anemia or platelet deficiencies. The research phase of the collaboration ended in 2001. GSK is responsible for the registration and worldwide marketing of Promacta.
