While Lead Case Managers (LCMs) are available to answer your questions about SPINRAZA and the support services Biogen provides, your healthcare provider is always your primary source of information for spinal muscular atrophy (SMA) and individual treatment decisions.

LCMs are available during extended hours from 8:30 AM to 8:00 PM ET, Monday through Friday, which means you can contact them from the privacy of your home. The toll-free call and the services are confidential and completely free.
