Exact Sciences revises distribution deal

Exact Sciences Corp., a Marlborough developer of cancer tests, said it has revised an agreement with Laboratory Corp. to extend how long the company can exclusively distribute a colon cancer test.

Laboratory Corp. will be the sole distributor through 2010.

In exchange for the extended exclusivity, Labcorp gave up rights to $3 million in royalty payments. And milestone payments available to Exact Sciences decrease to $40 million, from $45 million.
