SAN DIEGO, Calif., October 28, 2020Arena Pharmaceuticals, Inc. (Nasdaq: ARNA), and Longboard Pharmaceuticals, Inc., today announced the launch of Longboard Pharmaceuticals and the completion of a $56 million financing led by Farallon Capital Management, LLC, and other top tier healthcare investors, including Cormorant Asset Management, HBM Healthcare Investments, Highside Capital Management, and T. Rowe Price Associates, with participation from Arena. Longboard was previously a wholly-owned subsidiary of Arena and formerly known as Arena Neuroscience. Vincent Aurentz, Executive Vice President and Chief Business Officer of Arena, and Laurie Stelzer, Executive Vice President and Chief Financial Officer of Arena, will serve on Longboard’s Board of Directors.

Longboard is focused on developing novel central nervous system (CNS)-targeted assets discovered by Arena’s historical world-class G protein-coupled receptor (GPCR) research engine.  Proceeds from the financing will be used to support the development of LP352, a clinical stage program for treatment-resistant developmental and epileptic encephalopathies (DEE), and preclinical programs relating to LP143 and LP659 for the potential treatment of microglial neuroinflammatory diseases.

“When the new leadership team joined Arena in 2016, we realized the promise of the assets that were discovered and optimized over decades of world-class GPCR research. Our goal has been to maximize the value of the pipeline for shareholders, and more importantly to deliver potentially life-changing medicines to patients suffering from grievous illnesses. With the launch of Longboard, we believe these compounds will receive the focus they deserve, and Arena shareholders will continue to participate in the value of these assets via Arena’s equity position in the new company and future royalty streams,” said Amit D. Munshi, President & Chief Executive Officer of Arena.

“We are focused on advancing these compounds with the goal of helping underserved patients living with devastating neurological conditions,” stated Kevin R. Lind, President & Chief Executive Officer of Longboard. “I want to thank the Arena management team and Board of Directors for conceiving this idea, the broader Arena team for helping us execute on the strategy, and our new investors for supporting this endeavor. I look forward to leading Longboard as we strive to deliver multiple important medicines.”

LP352, LP143 and LP659 are investigational compounds that are not approved for any use in any country.
