Lemtrada, a pharmaceutical drug approved to treat multiple sclerosis, has been linked to serious side effects that can result in permanent damage and death. Lemtrada causes arterial dissection (tears in the arterial lining of the head and neck) and stroke, caused by brain bleeding or lack of blood supply to the brain. Lemtrada stroke and artery tears are life-threatening events that kill brain cells and cause permanent brain damage. Lemtrada is already viewed as a risky treatment that should be used only after other drugs fail; today, some safety experts believe the Lemtrada stroke risk tips the scales, such that Lemtrada side effects outweigh the drug's potential benefits.
A product of Genzyme, a subsidiary of the French pharmaceutical giant Sanofi, Lemtrada was approved in 2014 to treat relapsing forms of multiple sclerosis (MS) because it was found to offer better treatment outcomes over comparable drugs. At the same time, FDA safety experts were cautious about the risks posed by Lemtrada, ordering a comprehensive risk evaluation and mitigation strategy (REMS) to ensure serious Lemtrada risks be managed. Initial Lemtrada problems included anaphylactic responses and cancer; the danger of stroke from Lemtrada was only announced as a result of post-market adverse event reports to the FDA. In other words, MS patients who have taken the drug since its release in 2014 were not warned about the Lemtrada stroke risk and were thus unknowingly exposed to a life-threatening complication. Annual sales of Lemtrada in the United States exceeded $275 million in 2017.
Now Sanofi Genzyme (the American division of the French pharmaceutical giant Sanofi) faces serious questions regarding Lemtrada side effects and early safety testing. Persons and the family members of persons who suffered from Lemtrada stroke or arterial dissection are filing Lemtrada lawsuits against Genzyme. Filing a Lemtrada stroke lawsuit is the only means individuals and families have to obtain the compensation they deserve for suffering, damage, medical expenses and loss related to Lemtrada stroke or arterial dissection. In addition, filing a Lemtrada lawsuit claim is the best method for individual consumers to hold Sanofi Genzyme executives accountable for the safety of this popular drug.
