OxyContin maker Purdue Pharma and its owners, the members of the Sackler family, have offered to settle more than 2,000 lawsuits against the company for between $10bn and $12bn, the NBC News network reported on Tuesday, citing two people familiar with the mediation.
Purdue is among several drugmakers and distributors facing lawsuits that seek to hold them responsible for fueling the United States opioid addiction crisis, which has claimed thousands of lives.
The Stamford, Connecticut-based company said it was actively working with state attorneys general and other plaintiffs to reach a resolution, without specifying a settlement amount.
But Paul Hanly, a lead attorney for the cities and counties in the opioid litigation, said in an email to the Reuters news agency that the settlement figure was "made up" and "ridiculous".
Attorney Mary Jo White, who represents one wing of the Sackler family in the opioid litigation, declined to comment on the reported settlement offer. A Sackler spokeswoman also declined to comment.
A representative for the state attorneys general did not immediately respond to a request for comment.
