  • $240 million in potential milestone payments
  • Royalties ranging from the high single-digits to mid-teens on net sales
  • Beyond XOMA 358, XOMA adds three additional programs to its portfolio for which it is entitled to receive future royalties

EMERYVILLE, CA, USA I December 07, 2017 I XOMA Corporation (Nasdaq:XOMA), a pioneer in the discovery, development and licensing of therapeutic antibodies, today announced it has licensed the global development and commercialization rights for XOMA 358 to Rezolute, Inc. (OTCQB:ANTB), formerly AntriaBio, Inc., a biopharmaceutical company that specializes in developing therapies for metabolic and orphan diseases.

Under the license agreement, XOMA is entitled to receive up to approximately $240 million in exchange for the global XOMA 358 rights. The Company will receive payments as Rezolute achieves specific milestones associated with financing activities, clinical development success, regulatory milestones and commercial sales. The terms include an allocation of $5 million in shares of Rezolute common stock to XOMA and a further $13 million in cash and common stock to be paid as Rezolute completes certain financing milestones. In addition, XOMA is eligible to receive royalties ranging from the high single-digits to mid-teens on net sales. Rezolute is responsible for all development, regulatory, manufacturing and commercialization activities under the license. The Company is also entitled to receive low single-digit royalties on net sales of AB101 and other products developed from Rezolute’s extended release and oral plasma kallikrein inhibitor platforms.

“Out-licensing XOMA 358 is another milestone in executing our strategy to create long-term value for our shareholders. Rezolute’s focus on insulin-related conditions makes them an ideal company to continue XOMA 358’s clinical development,” stated Jim Neal, Chief Executive Officer of XOMA. “This license agreement further expands our portfolio of partner-funded programs that have the potential to generate substantial milestone and royalty payments. We welcome Rezolute to our broad portfolio of partners, including Novartis, Five Prime and Nanotherapeutics, who continue the development of our product candidates.” 

XOMA 358 is a first-in-class fully human antibody that inhibits the effects of elevated insulin (hyperinsulinemia) via allosteric modulation of the insulin receptor. XOMA 358’s novel mechanism of action makes it well-suited as a therapy for severe, persistent hypoglycemia caused by hyperinsulinemic conditions, such as congenial hyperinsulinism (CHI). XOMA demonstrated clinical proof-of-concept through Phase 2a studies, and Rezolute plans to advance XOMA 358’s clinical development in 2018. The compound has received designated orphan status in the U.S. and European Union.
