Why Achillion Pharmaceuticals Inc. Shares Soared

Although we don't believe in timing the market or panicking over market movements, we do like to keep an eye on big changes -- just in case they're material to our investing thesis.

What: Shares of Achillion Pharmaceuticals (NASDAQ: ACHN  ) , a clinical-stage biopharmaceutical company focused on researching therapies to treat hepatitis C, climbed as much as 44% on speculation that it could be a buyout target.

So what: The primary impetus for Achillion's spike is Merck's (NYSE: MRK  ) $3.85 billion purchase of Idenix Pharmaceuticals (NASDAQ: IDIX  ) , which was announced before the opening bell today. According to CNBC reporter David Faber, the 239% premium paid for Idenix resulted from a bidding war between Merck, Johnson & Johnson, and surprisingly AbbVie, which has its own direct-acting antiviral combo drug under review by the Food and Drug Administration. The thought here is that J&J, AbbVie, or some other suitor could be interested in Achillion's pipeline considering its focus on hepatitis C. The Centers for Disease Control and Prevention says more than 3 million people in the U.S. have hepatitis C (although most people are unaware they have the disease), with some 180 million people worldwide carrying the disease, per the World Health Organization.

Now what: The rumor mill is certainly working overtime today considering what I believe to be the insane price Merck paid to acquire a company that had four investigational therapies placed on clinical hold over the past four years.

Achillion is, unfortunately, in a somewhat similar boat. Although it has four investigational products in trials, its lead drug, sovaprevir, has been on clinical hold since last summer after investigators found elevated ALT liver enzyme levels in patients following a phase 1 study. Its future is as cloudy as ever with management expecting the clinical hold to have been lifted last year. Even with additional phase 1 and 2 studies under way, what value is there if Achillion, like Idenix, can't get any of its therapies safely past midstage studies? In addition, with hepatitis C patients already welcoming Gilead Sciences' Sovaldi with open arms, and maybe AbbVie's direct-acting antiviral combo later this year, what market share would Achillion be looking at when its drugs hit pharmacy shelves in two or three years? I would suggest investors ignore their urge to trade on emotion and stick to the sidelines here.
