Safety and Efficacy of Galantamine in Patients With Dementia With Lewy Bodies

Summary

TRIAL SUMMARY: This is an open-label, 24-week, investigator initiated study to evaluate the safety and efficacy of galantamine (16 8 to 24 mg/day; flexible dosing) in the treatment of Dementia with Lewy bodies. The primary efficacy variables will be the NPI -12, the COGDRAS tests of attention and visuospatial orientation, and the ADCS-CGIC. The secondary efficacy variables will be the MMSE, ADCS-ADL-Inventory, ADAS-Cog, PSQI, and the use of concomitant rescue antipsychotic medication. PET scanning will be obtained on 10 patients at one site. An interim analysis will also be performed. Safety outcome measures will be adverse event reports, vital signs, physical examinations, ECG, laboratory parameters and the UPDRS (motor subscale).
