The new plan allows plaintiffs who sued Purdue to opt in to receive their settlement or reserve their right to file a civil suit against the billionaire Sackler family.

Bankrupt opioid manufacturer Purdue and the Sackler family have agreed to a $7.4 billion settlement to resolve opioid claims by state and municipal governments and individuals.

Other drugmakers, distribution companies, pharmacy chains and others have already reached opioid lawsuit settlements worth about $50 billion, according to an Associated Press tally. Purdue's, which would also include about $900 million from company coffers, would be among the largest if finalized.
