Ambroxol as a Novel Disease Modifying Treatment for Lewy Body Dementia
Sponsor: London Health Sciences Centre Research Institute OR Lawson Research Institute of St. Joseph's
Summary
This is a randomized, placebo-controlled, double-blind study investigating whether the medication Ambroxol is safe,effectiveness and well tolerated for the treatment of Lewy Body Dementia (LBD). Currently the main treatments for patients with LBD target symptom management. However, none of the medications treat the underlying cause of the disease, which includes the accumulation of protein in the brain. Therefore, even if patients respond well to symptomatic treatment, they continue to deteriorate. Therefore, the purpose of the current study is to make sure Ambroxol is safe to take long term and to test the effects of Ambroxol in treating the cognitive impairments associated with LBD by modifying the underlying causes of the disease. There will be a total of 15 people participating this this study, which will last 52 weeks. Over the study period patients will undergo clinical, neuropsychological and neuroimaging assessment to assess changes.

Ambroxol Hydrochloride
The treatment regimen consists of a titration phase and a maintenance phase. Participants begin the titration phase (Weeks 1 and 2) taking 6 capsules a day (450mg or 0 mg) divided BID (3 capsules in the morning and 3 capsules in the evening). The first medication dose will be taken at the end of Baseline visit and in the presence of the study Neurologist. Possible side effects will be observed for 30 minutes. Medication dose will increase bi-weekly to 12 capsules on Weeks 3 and 4, and 18 capsules on Weeks 5 and 6 divided BID. At the end of titration (Week 5) participants will have reached a maximum of 1350mg or 0mg per day, depending on group allocation. In the maintenance phase, participants will remain in their maximum dose (1350mg or 0mg) from Week 5 to Week 52 (End of Trial).
