NEA Participates in $40M Investment in Hyperion Therapeutics

Demonstrates Continued Commitment to Outstanding Teams and Products

MENLO PARK, Calif.--(BUSINESS WIRE)--New Enterprise Associates (NEA) has invested in South San Francisco, CA-based Hyperion Therapeutics, a biopharmaceutical company focused on the development and commercialization of gastrointestinal and hepatology therapies for the treatment of Urea Cycle Disorders (UCD) and Hepatic Encephalopathy (HE). NEA joins Sofinnova Ventures, Highland Capital Partners, and WRF Capital in this $40 million Series B financing.

“NEA is thrilled to be part of this investment, as we have great confidence in Hyperion’s innovative leadership team”

“NEA is thrilled to be part of this investment, as we have great confidence in Hyperion’s innovative leadership team,” said Michael Raab, NEA Partner and newly appointed Hyperion Board of Director. “The therapies being commercialized and developed by Hyperion are critical to extending and improving the lives of those suffering with UCD, as the company holds the only two FDA approved drugs for this condition. We are pleased to partner with this extraordinary company and look forward to the profound impact their therapies will have on those affected by UCD and HE.”

Proceeds from this $40 million financing will be used to complete the company’s licensing agreement with Medicis Pharmaceutical Corporation, build out the management team, advance clinical trials and begin US promotion of the only two FDA approved compounds for the treatment of UCD, AMMONUL^® (sodium phenylacetate and sodium benzoate) Injection 10%/10% and BUPHENYL^® (sodium phenylbutyrate). An urea cycle disorder is an inherited, inborn error of the metabolism. Patients with UCD lack or are deficient in one of the key enzymes that comprise the urea cycle, the body’s primary vehicle for removing ammonia from the bloodstream, which, left untreated, can result in brain damage, coma or death.

"NEA and this group of investors will make it possible for Hyperion to have immediate and significant impact on patient lives,” said Chris Rivera, President and CEO of Hyperion. "We searched for investment partners that saw the critical need for the solution to the problems we solved, and are thrilled with this investment consortium. We welcome NEA, Mike and their experience and guidance to the Board. This along with our other investors and Board members will aide Hyperion in achieving its corporate objectives.”
