Item 8.01    Other Information.

On July 9, 2018, Ligand’s wholly-owned subsidiary Crystal Bioscience, Inc. entered into a Research & Development Agreement with Janssen Research & Development, LLC , one of the Janssen Pharmaceutical Companies of Johnson & Johnson, for the development by Ligand of a heavy-chain-only (“HCO”) version of the OmniChicken™ transgenic chicken platform.  Following successful development of the HCO OmniChicken, Janssen may request that Ligand conduct one or more HCO OmniChicken immunization campaigns with novel antigens designated by Janssen Research & Development, LLC, for discovery of fully-human antibodies to be further developed and commercialized by Johnson & Johnson. 
 
Ligand is eligible to earn defined milestone payments upon achievement of pre-determined deliverables.  Upon completion of development of the HCO OmniChicken Ligand may make the HCO OmniChicken platform available to other commercial partners. 
 
Ligand’s HCO OmniChicken platform will have two multi-specific applications: the generation and discovery of domain antibodies and the generation and discovery of polyclonal HCO antibodies.
 
Ligand's OmniAb® therapeutic antibody platforms, OmniRat®, OmniFlic®, OmniMouse® and OmniChicken™, produce highly diversified, fully human antibody repertoires optimized in vivo for manufacturability, therapeutic efficacy and reduced immunogenicity.  OmniChicken™ chickens have been genetically modified to have the immunoglobulin genes replaced with corresponding human genes.
