Ligand Pharmaceuticals acquires Metabasis Therapeutics

Jan 28 2010

Ligand Pharmaceuticals Incorporated (NASDAQ:LGND) announced that it has completed the acquisition of Metabasis Therapeutics, Inc. (NASDAQ:MBRX), following approval of the transaction by Metabasis stockholders yesterday. As a result, Ligand gains a fully funded partnership with Roche, additional pipeline assets and drug discovery technologies and resources. The transaction was first announced on October 27, 2009.

“We are excited about this acquisition and the opportunities it presents for our shareholders”

“We are excited about this acquisition and the opportunities it presents for our shareholders,” said John L. Higgins, President and Chief Executive Officer of Ligand. “The acquisition of Metabasis builds on our strategy to cultivate a robust pipeline with a broad array of royalty bearing assets and early stage pipeline programs.”

In the acquisition, Ligand paid $1.6 million in cash or about $0.046 per Metabasis share to Metabasis' stockholders. In addition, Metabasis stockholders received four tradable Contingent Value Rights (CVRs), one CVR from each of four respective series of CVRs, for each Metabasis share. The CVRs will entitle Metabasis stockholders to cash payments as frequently as every six months as cash is received by Ligand from proceeds from Metabasis’ partnership with Roche or the sale or partnering of any of the Metabasis drug development programs, among other triggering events.

Primary Acquired Assets

• Fully funded partnership with Roche to develop new treatments for hepatitis C viral infection utilizing the proprietary HepDirect® liver-targeting technology. The lead HepDirect nucleoside, MB11362, was declared a clinical candidate in the second quarter of 2009. Roche will fund 100% of program costs and will make milestone and royalty payments upon the achievement of certain development events and commercialization of MB11362 and/or other applicable HepDirect compounds covered under the agreement.
• Glucagon Receptor Antagonist Program – Metabasis has developed chemically novel, potent, orally bioavailable glucagon antagonists for treating type 2 diabetes. The lead compound, MB11262, has shown significant and consistent lowering of blood glucose when dosed orally in numerous diabetic animal models and is currently in pre-clinical development.
• Thyroid Receptor Beta Agonist Program – Metabasis has developed and evaluated in clinical trials a liver-targeted TR Beta agonist, MB07811, using HepDirect prodrug technology and other structural characteristics for the treatment of hyperlipidemia. In addition, there is an advanced discovery program to identify second-generation TR Beta agonists with potential improvements in the therapeutic index for lowering cholesterol and other lipids associated with cardiovascular risks.
• PeriCor Therapeutics – Metabasis has a common stock ownership position in privately-held PeriCor Therapeutics, Inc. PeriCor sublicensed rights from Metabasis to acadesine and three additional Adenosine Regulating Agents in 2005. PeriCor licensed acadesine to Schering-Plough Corporation (now Merck & Co.) and the compound is in a Phase III clinical trial for the prevention of adverse cardiovascular and cerebrovascular outcomes in patients undergoing coronary artery bypass graft surgery.
• HepDirect Technology – HepDirect technology supplements Ligand’s core drug discovery technology platform of ligand-dependent gene expression and ultra-high throughput combinatorial chemistry screening. HepDirect is a prodrug technology that targets delivery of certain drugs to the liver by using a proprietary chemical modification that renders a drug biologically inactive until cleaved by a liver-specific enzyme.
• Other Product Candidates and R&D Programs – Metabasis has other product candidates, including MB07803 for diabetes and pradefovir for hepatitis B, which have been evaluated in clinical trials and early stage R&D programs including glucokinase activators for diabetes and DGAT-1 inhibitors for obesity.
