SAN DIEGO--(BUSINESS WIRE)--

Ligand Pharmaceuticals Incorporated (NASDAQ: LGND) announces that its partner HanAll Biopharma successfully out-licensed antibody projects that were discovered by HanAll using Ligand’s OmniAb^® antibody discovery platform. The licensing events triggered $6 million of payments to Ligand. HanAll has had access to the OmniAb platform since December 2014 and is developing multiple antibody projects in the immunno-oncology and autoimmune areas using this platform. Under the license agreements with HanAll, Ligand is eligible to receive milestones and royalties on the successful development of antibodies and to share sub-license revenue on out-licensed antibodies.

“These are excellent licensing transactions for HanAll and for Ligand, putting a clinical-stage antibody into the hands of two partners to advance the development of the program in markets around the world. The licenses illustrate the value and potential of the OmniAb platform for delivering novel antibodies that succeed through the intense discovery selection process,” said John Higgins, Chief Executive Officer of Ligand. “We are very pleased with HanAll's success in quickly moving one of its novel antibodies into human trials in 2017 and in subsequently securing two license agreements for the antibody. Ligand has a best-in-class antibody discovery technology with its OmniAb platform offering three distinct species for drug discovery. Since acquiring the technology less than two years ago, Ligand has expanded its portfolio of OmniAb partners and has secured substantial partnering payments as the programs advance.”

Including these payments, Ligand now anticipates total revenue for full year 2017 to be approximately $140 million with adjusted EPS to be between $3.13 and $3.16. Previous guidance was for revenue to be between $134 and $136 million and for adjusted earnings per share to be between $2.95 and $3.00.
