J&J in talks to reduce $1.5 bln Elan deal price: source

BOSTON/NEW YORK (Reuters) - U.S. health-care firm Johnson & Johnson (JNJ.N) is in talks to cut the price of a $1.5 billion deal with Irish drugmaker Elan Corp (ELN.I), a source familiar with the negotiations said on Sunday.

J&J agreed in July to pay $1 billion for an 18.4 percent stake in Elan and $500 million for a majority stake in its pipeline of experimental Alzheimer's drugs.

However, Elan and J&J had been widely expected to renegotiate the deal after a court ruled the agreement breached a partnership between Elan and Biogen Idec Inc (BIIB.O).

A U.S. judge earlier in September ruled that the deal -- which has not yet closed -- breaches Elan's 50-50 partnership to sell multiple sclerosis drug Tysabri with Biogen, a Cambridge, Massachusetts-based biotech company whose shareholders include billionaire investor Carl Icahn.

The Wall Street Journal reported on Sunday that J&J is attempting to cut at least $100 million off the $1 billion in cash it agreed to pay as part of the deal and that the new terms could be announced in the coming days.

J&J was not immediately available for comment. Elan declined comment.
