Esperion Gets $33M To Continue Work On Cholesterol Buster

ANN ARBOR -- Esperion Therapeutics Inc. announced that it has completed a $33 million preferred stock financing led by new investor Longitude Capital.

Esperion is developing and commercializing new therapies to treat high cholesterol that can be taken in pill form, and which don't cause some of the side effects of current statin drugs.

Existing investors Aisling Capital, Alta Partners, Domain Associates, Arboretum Ventures and Asset Management also participated in the financing. In connection with this financing, Longitude's Patrick Enright will join Esperion's board of directors.

"This financing allows us to continue to advance our novel lead product candidate, ETC-1002, for which we have 100 percent worldwide rights, in multiple ongoing and planned Phase 2 clinical trials," said Tim Mayleben, Esperion's president and CEO.

Esperion says ETC-1002 lowers low-density cholesterol, the so-called bad cholesterol. It can be taken by mouth just once a day. It's the first such therapy to target known lipid and carbohydrate metabolic pathways to lower levels of LDL-C while avoiding many of the side effects fo current LDL-C lowering medications.

Phase 2a clinical trials of ETC-1002 conducted so far have demonstrated significant average LDL-C reductions -- as high as 43 percent -- and reductions about equal to statins in levels of high sensitivity C-reactive protein, or hsCRP, a key marker of inflammation associated with cardiovascular disease.

ETC-1002 has been well tolerated and is not associated with serious side effects, and there have been no serious adverse events in over 230 ETC-1002 treated patients. And its one-pill-a-day administration is a major advantage over other therapies currently in development that, if approved, will require regular injections.

It is estimated that more than two million U.S. adults have discontinued statin therapy because of muscle pain or weakness. Because symptoms of muscle pain or weakness occur in up to 20 percent of patients on statin therapy in clinical practice, Esperion believes the size of the statin-intolerant market is poised to grow if a novel non-statin therapy becomes available.

"To date, we have used our resources efficiently to get us to this critical stage of development with what I believe is an LDL-C lowering therapy with differentiated non-statin mechanisms," added Roger Newton, Esperion's executive chairman and chief scientific officer. "We intend to use this financing to advance ETC-1002 through the next important phase of development."

Said Patrick Enright of Longitude: "I look forward to working with Roger, Tim and the entire Esperion team to realize the full potential of ETC-1002 in patients with elevated LDL-C who cannot tolerate statin therapy."
