A Phase 3, multicenter, randomized, double-blind, placebo-controlled, parallel-design study to assess the efficacy, safety, and tolerability of AVP-786 (deudextromethorphan hydrobromide [d6-DM]/quinidine sulfate [Q]) for the treatment of agitation in patients with dementia of the Alzheimer’s type
Information about the drug that will be tested in the study
A capsule taken orally twice a day
Is the drug already on the market for another medical condition?
Will all participants receive the same drug?
Participants will be selected at random to either receive one of the following options:
- A capsule of AVP-786 administered twice daily (dose 1)
- A capsule of AVP-786 administered twice daily (dose 2)
- One placebo capsule (also called a dummy treatment which is an inactive substance identical in appearance to the drug being tested with no active therapeutic effect) administered twice daily.
Neither the participant nor his/her doctor will know if the person is receiving the investigational drug or the placebo.
Information about participating in the trial
What are the researchers trying to find out?
The purpose of this study is to evaluate the safety and efficacy of AVP-786 for the treatment of agitation in people with dementia of the Alzheimer's type
How long will the treatment last?
What your involvement will entail?
During the study, participants (and/or their caregivers) will be asked to complete different tests that will assess the participants’ behaviour, functioning, quality of life, cognition and the level of burden on the caregiver.
Further information on the procedures, tests and number of visits can be obtained from the study team.
