Palo Alto-based CV Therapeutics signed a lucrative deal earlier this week with New York-based TPG-Axon Capital in which TPG-Axon Capital, a New York hedge fund, agreed to pay up to $185 million in exchange for the payment of a royalty in the amount of fifty percent of its North American sales of Lexiscan, reported the San Jose Business Journal. 

According to the San Jose Business Journal, the U.S. Food and Drug Administration("FDA") recently approved CV Therapeutics’s Lexiscan injection, an A2A adenosine receptor agonist, for use as a pharmacologic stress agent for patients unable to undergo adequate exercise for stress tests.

The San Jose Business Journal reported on the terms of the deal as follows:

[T]he deal with. . . .TPG-Axon Capital includes $175 million on closing of the transaction and a potential future milestone payment of $10 million. . . .CV Therapeutics retains rights to the other 50 percent of royalty revenue from North American sales of the product [by its partner Astellas Pharma US, Inc., and also may receive a royalty on another Astellas product under the terms of the company’s collaboration agreement with Astellas Pharma US Inc.

The San Jose Mercury News further reported:

[I]nvestment bank Leerink Swann described the $175 million payment as "a surprisingly positive transaction," because other heart stressing agents already are on the market.

"The magnitude of this deal is much bigger than we would expect since physicians we have queried seem relatively uninterested in a novel cardiac stress agent," the report said.

It goes with out staying that a deal of this magnitude dramatically improves CV Therapeutics’ cash flow situation.  According the the San Jose Business Journal, CV Therapeutics plans to use the financing to meet a 2010 debt obligation and to also support its commercialization plans for Ranexa.
