A U.S. judge said on Sept. 1 he would approve OxyContin maker Purdue Pharma LP’s bankruptcy reorganization plan, clearing a path to resolve thousands of opioid lawsuits and shielding the company’s wealthy Sackler family owners from future opioid litigation.

Endo International Plc agreed to pay $35 million to settle a lawsuit by Tennessee local governments and on behalf of a child allegedly born addicted to painkillers accusing the drugmaker of fueling the opioid epidemic, the company announced July 22.

Fifteen more states reached an agreement with Purdue Pharma LP and members of its wealthy Sackler family owners that moved the OxyContin maker a step closer to resolving widespread opioid litigation and exiting bankruptcy protection.

Four drugmakers, including Johnson & Johnson and Teva Pharmaceutical Industries Ltd., will go to trial on April 19 over claims they helped fuel an opioid crisis that has resulted in nearly 500,000 overdose deaths in the United States.

U.S. states are seeking a combined $26.4 billion from three major drug distributors and Johnson & Johnson to settle opioid litigation against the companies, the Wall Street Journal reported, citing people familiar with the matter.

Mallinckrodt Plc received a subpoena from the U.S. Securities and Exchange Commission for documents related to the drugmaker’s lawsuit against the U.S. Department of Health and Human Services (HHS).
