Esperion Therapeutics

(ESPR) - Get Esperion Therapeutics, Inc. Report

fell almost 30% Monday, because some investors -- subscribers to a major medical journal -- had the first look at highly anticipated clinical data on the company's arterial plaque-reducing drug, ETC-216.

Evidently, these investors -- who had early access to a study published in this week's issue of the

Journal of the American Medical Association

-- weren't happy with the results. The heavy selling of Esperion shares on Monday erased about $200 million from the company's market value. The stock fell another 1% on Tuesday.

Why did these investors get a trading advantage over everyone else? Because rules enforced by


prohibit companies like Esperion from speaking publicly about journal articles until the official publication date. The same restrictions are applied to the media.

But no such rules apply to


subscribers, who typically get their issues by mail before the embargo is lifted. Lucky them, I guess. If they invest,


rules provide them with an easy way to trade before information is widely disseminated in the market -- yet another example of how medical research organizations and scientific journals facilitate the selective disclosure of material, market-moving medical research.

I called

editor-in-chief, Dr. Catherine DeAngelis, refused to talk to me, but a spokeswoman said the financial markets are not

I guess no one at

Esperion isn't entirely blameless. The company was fully aware that its clinical data were getting out into the market on Monday, but it remained silent. Like


editor-in-chief, Esperion management wouldn't discuss the issue. An Esperion spokesman would only say the company was bound by the journal's rules and wouldn't be able to discuss the ETC-216 data until a Tuesday afternoon conference call after the embargo lifts.

I'm sure frustrated Esperion shareholders are happy with this attitude. Apparently, rules set down by medical journal editors living in an ivory tower -- and not in the real world -- trump the financial interests of the company and its shareholders.

And you'd think Esperion management would be especially sensitive to the needs of their shareholders, given that the company was embroiled in the stock trading scandal involving hedge fund manager Scott Sacane and his Durus Capital Management.



article discussing results from the ETC-216 study was to be released publicly Tuesday night. Esperion is holding a conference call to discuss the results, and presumably, to defend the drug and the data. (I

discussed the results earlier today in the Columnist Conversation.)

At this point, I'm not as concerned over whether the ETC-216 data are positive or not, or whether investors who got an early peek interpreted the data correctly. What irks me is that medical journals like


(or as I've written previously, medical research groups like the American Society of Clinical Oncology), continue to ignore the serious financial ramifications caused by their practices.

Simply put, medical research moves stocks. How can journals like


ignore that fact?
