Actos, known generically as pioglitazone, is a medication used to treat patients with Type 2 diabetes. Takeda Pharmaceutical and Eli Lilly gained approval to sell the drug in the United States in 1999, although the drug is now solely manufactured by Takeda in the US. Actos is part of the thiazolidinedione drug class, which also includes the medication Avandia (rosiglitazone). Actos gained more popularity when Avandia was linked to heart attacks, but research linking it to bladder cancer has sparked safety concerns as well as thousands of lawsuits.
There is an ever-growing body of research showing that Actos is associated with an increased risk of bladder cancer. In fact, the drug was suspended in France and Germany at the request of those countries regulators because of its cancer risks. The U.S. Food and Drug Administration (FDA) has also addressed the potential dangers of Actos by updating its safety label to warn that it may increase the risk of bladder cancer after only one year of use.
Amidst mounting safety concerns, thousands of Actos lawsuits have been filed around the country. Some have been filed in state court but most have been filed in federal court as part of the multidistrict litigation entitled In Re: Actos (Pioglitazone) Products Liability Litigation. The MDL is centralized to the U.S. District Court for the Western District of Louisiana. Jerrold S. Parker, founding partner of Parker Waichman LLP, serves on the Plaintiffs’ Steering Committee in the litigation.
See below for a comprehensive timeline that includes the history of Actos, dates of label changes and updates on lawsuits and potential settlements.
