BioDelivery fight escalates - Investor wants to eject management, could win rights to experimental treatment

BioDelivery Sciences International of Morrisville could lose the rights to its most promising product, an experimental pain patch for cancer patients, if it doesn't resolve a dispute with one of its largest investors.

A fund controlled by New York investment firm Elliott Associates claims that BioDelivery is wasting money and compromising the regulatory approval of the patch. The fund wants to oust BioDelivery's management and could win rights to the patch.

The dispute started in June and continues to escalate, according to filings submitted Thursday with the Securities and Exchange Commission.

BioDelivery and Elliott accuse each other of breaching a collaboration agreement to develop and market the patch, SEC filings show.

Elliott claims BioDelivery is spending too much time and money on other projects and is in danger of running out of cash. The investor is upset that it wasn't consulted before BioDelivery tinkered with the way the patch is being tested and notified regulators about the changes.

Also, Elliott claims that BioDelivery included California patients in the tests without asking the patients for permission.

According to the filings: BioDelivery acknowledged that the Elliott fund could gain certain rights to the patch and that it is trying to address some of the problems fueling the dispute. But Elliott doubted they can be fixed and terminated its agreement with the company.

Mark Sirgo, BioDelivery's chief executive, and Frank O'Donnell, chairman of BioDelivery, did not return calls for comment.

O'Donnell is also general manager of Hopkins Capital Group, a Baltimore venture capital firm and BioDelivery's largest investor. Hopkins would have to pump more money into BioDelivery to pursue the fight with Elliott.

Settling the dispute could cost millions, said Jim Verdonik, a Durham securities lawyer.

"This mess is a litigator's dream," Verdonik said. "The legal fees will be enormous; that's about the only thing you can bet on."

The patch is BioDelivery's best chance to generate product revenue.

A more advanced treatment for nausea failed regulatory review in February. Three other experimental drugs have yet to be tested in people. The company reported $5.2 million in cash reserves at the end of June, enough to finance operations for about six months.

Called Bema Fentanyl, the patch attaches to the inside of the mouth and delivers a narcotic already available as a pill or in an injection. Bema Fentanyl is designed for patients who receive chemotherapy or treatment in the emergency room, or who are coming out of surgery.

The patch is in the final stages of testing and is projected to come to market in the first half of 2008.

BioDelivery estimates that Bema Fentanyl could generate up to $250 million in annual sales.

Elliott funded part of the work that BioDelivery did to develop and test Bema Fentanyl through a fund called Clinical Development Capital IV. About a month ago, the fund also helped BioDelivery buy the technology behind the patch.

Clinical Development has pumped about $7 million into BioDelivery since the collaboration agreement took effect July 14, 2005.

In return, the investor was to receive a portion of the sales and also gained a 22 percent stake in BioDelivery.

BioDelivery shares fell 5 cents to $2.28 Thursday.
