Ligand Enters Into Commercial License and Supply Agreement with Amgen for Rights to Use Captisol in the Formulation of AMG 330

SAN DIEGO--()--Ligand Pharmaceuticals Incorporated (NASDAQ: LGND) today announced that it has entered into a commercial license and supply agreement with Amgen, granting rights to use Ligand’s Captisol technology in the formulation of AMG 330. Captisol is a patent protected, chemically modified cyclodextrin with a structure designed to optimize the solubility and stability of drugs. AMG 330 is an anti-CD33 x anti-CD3 (BiTE®) bispecific antibody construct. It is being investigated as a treatment for acute myeloid leukemia by Amgen.

This license agreement replaces the prior research agreement which allowed Amgen to evaluate AMG 330 with Captisol in preclinical and early clinical studies. Under this new commercial license agreement, Amgen receives exclusive worldwide rights to combine Captisol with AMG 330 for use in humans for a wide variety of therapeutic indications. In addition to an upfront payment, Ligand is entitled to potential milestone payments, royalties and revenue from future sales of AMG 330 formulated using Captisol.

“This agreement expands our license relationship with Amgen on AMG 330,” said John Higgins, Chief Executive Officer of Ligand Pharmaceuticals. “Ligand’s portfolio of fully-funded shots on goal continues to grow and contains a large number of Captisol-enabled drugs targeted to a number of serious diseases with unmet medical needs.”
