NEW YORK (Dow Jones)--Savient Pharmaceuticals Inc. (SVNT) shares lost nearly half their value Monday after the drug company said it hasn't yet had success in its attempt to sell itself.
A big takeover premium had been built into the stock after its gout treatment, Krystexxa, was approved by the U.S. Food and Drug Administration last month. After the approval, the company made the unusual move of trying to launch the drug and sell itself at the same time, all without raising cash.
But on Monday, Savient said its process to identify a "strategic transaction for the sale of the company" didn't result in a sale at this time. Savient said it is still working toward the commercial launch of Krystexxa, which it expects to be available by prescription in the U.S. later this year.
In recent trading, shares plunged 43% to $12.32 on heavy volume, a loss in market capitalization of about $634 million from Friday's close, and earlier fell as low as $10.43. The stock is now below the $14 range where it had traded before Krystexxa was approved last month.
The company, which couldn't be immediately reached for comment, didn't provide details on why it hasn't been able to secure a buyer, but analysts said the difficulties likely stemmed from uncertainty surrounding the market size for Krystexxa.
Krystexxa targets a hard-to-treat form of gout, a painful form of arthritis. The company has put the potential U.S. market size at 170,000 patients, but several analysts' estimates were much lower.
Summer Street Research Partners analyst Carol Werther estimated the U.S. market size for the drug was closer to 10,000 to 25,000 patients, in part because of the drug's side effects. She said large pharmaceutical companies likely want to wait to see how the launch goes before they consider buying the company.
Companies that had been seen as potential acquirers of Savient included those that already sell drugs to rheumatologists for diseases like arthritis, such as Johnson & Johnson (JNJ), Abbott Laboratories (ABT), Pfizer Inc. (PFE) and Amgen Inc. (AMGN).
Savient hasn't yet determined the price of the drug, but company executives said on a conference call last month that it would have a "significant premium or a multiple" above the anti-inflammatory biologics that command more than $20,000 a year.
Roth Capital Partners analyst Andrew Vaino, who estimated the potential U.S. market size for the drug is about 40,000 to 45,000 patients, said he doesn't think an acquisition is off the table for Savient.
"Just because they're not selling themselves today doesn't mean that in six months, if things are going well with the Krystexxa launch, that they won't be able to sell themselves at that point," Vaino said.
With expectations of a takeover getting pushed out, market observers think Savient may soon need to tap the capital markets. Roth's Vaino said Savient will likely want to do a capital raise sooner rather than later, before the balance sheet deteriorates.
