Despite living with multiple sclerosis since 1997 and taking a series of drugs to treat the neurodegenerative disease, Kimberley A. Yout of Hanover continued working for years at her full-time job as a money manager for a Boston bank while modeling in her spare time.
That changed on Aug. 28 of last year when Yout was diagnosed with PML, a rare brain infection that developed as a side effect of a drug, Tysabri, she had been taking for six years. Her speech became slurred and her gait unsteady. “I’ve lost my independence,” said the 45-year-old Yout.
Now she is suing the two companies that marketed Tysabri — Biogen Idec Inc. of Weston and Irish drug maker Elan Pharmaceuticals Inc. — in Middlesex Superior Court in Woburn.
