Tysabri patients who have developed Progressive Multifocal Leukoencephalopathy  (PML) and the families of those who have died from the disease have the right to seek compensation for their injuries. Our firm of national pharmaceutical attorneys can help you file a Tysabri lawsuit.


Tysabri, developed as Natalizumab, is a medication intended to treat those with multiple sclerosis or Crohn’s disease. While the drug is effective at treating the symptoms of both diseases, some consumers have developed a rare and often fatal neurological condition called progressive multifocal leukoencephalopathy (PML). This condition includes symptoms of weakness, impaired speech, paralysis, vision loss, and cognitive degeneration that usually proves fatal to victims.

While Tysabri was intended to help those with multiple sclerosis or Crohn’s disease, the effects of PML are so devastating that Tysabri can end up destroying or even ending the lives of those it was intended to help. If Tysabri has harmed you, you and your loved ones have the right to file a lawsuit to seek compensation for damages. Our firm has extensive experience in pharmaceutical law, and for over 30 years we have helped those who have been harmed by dangerous drugs and pharmaceutical companies seek compensation for their injuries.
