Clinical Trial Readiness for SCA1 and SCA3 (READISCA)


The investigators plan to fill the gap between the current state of clinical trial readiness and the optimal one for SCA1 and SCA3, which are fatal rare diseases with no treatments. Through US-European collaborations, the investigators will establish the world's largest cohorts of subjects at the earliest disease stages, who will benefit most from treatments, validate an ability to detect disease onset and early progression by imaging markers, even prior to ataxia onset, and identify clinical trial designs that will generate the most conclusive results on treatment efficacy with small populations of patients.


  • Blood and cerebrospinal fluid samples
  • Imaging
  • Patient health questionnaires

For study details, please contact Stephen Gullet:


  • Signed informed consent (no study-related procedures may be performed before the subject has signed the consent form)
  • Subjects of either sex aged 18 to 65 with presence of symptomatic ataxic disease or asymptomatic mutation carrier or
  • Subjects with definite molecular diagnosis of SCA1 or SCA3 or another affected family member
  • Subjects of any age with previous diagnosis of Early stage SCA1 and SCA3
  • Subjects capable of understanding and complying with protocol requirements
  • No changes in physical/occupational therapy status within two months prior to enrollment

Additional criteria apply, please contact Stephen Gullet for more information:
