Fasudil fOr redUcing elopemeNt and Spatial Disorientation

The study population will consist of subjects with dementia and wandering behaviors of elopement and/or getting lost. While it is anticipated that most participants will be residing at home (with caregiver support), subjects may live in another setting such as a group home, an assisted living unit, or in a long-term care facility, provided that a caregiver, formal or informal, has sufficient contact with the subject to permit accurate completion of the necessary assessments. Enrolled subjects will enter the Open-Label Phase and receive treatment with fasudil 90 mg/day (30 mg three times daily \[tid\]) for 6 weeks in Open-Label Period 1. Responders (i.e., subjects who improve 2 points or more on the GIW) will proceed to the Double-Blind Phase. Subjects in whom fasudil is well-tolerated (i.e. subjects with ≤ 2 drug-related AEs of mild intensity, no drug-related AEs of greater than mild intensity, and creatinine level of \< 1.5 mg/dL at all times during the period) and who do not respond will enter Open-Label Period 2, and be dosed with fasudil 180 mg/day (60 mg tid) for 6 weeks. Responders will proceed to the Double-Blind Phase and non-responders will move to the final post-treatment visit. In the Double-Blind Phase, subjects will receive treatment with either placebo or the dose they responded to in the Open-Label Phase (90 mg/day or 180 mg/day) for 6 weeks (Double-Blind Period 1), following which treatment assignment will be crossed over for 6 weeks (Double-Blind Period 2). A final post-treatment visit will occur 14 days after the last dose of study drug. Visits may be performed by qualified healthcare professionals at home or other care setting, or at a doctor's office/clinic. Interviews may be performed by telephone and/or telemedicine as appropriate.
