Long term, extension study of the safety and efficacy of AVP-786 for the treatment of agitation in patients with dementia of the Alzheimer's type
This is an Phase III - Extension study.
Only participants who have successfully completed previous Phase III studies with AVP-786 can be enrolled (15-AVP-786-301, 15-AVP-786-302, 12-AVR-131, or 17-AVP-786-305).
Information about the drug that will be tested in the study
Oral capsules twice daily
Is the drug already on the market for another medical condition?
Will all participants receive the same drug?
Participants will be selected by chance to receive one of the following options:
- An oral capsule of AVP-786 twice daily (dose 1)
- An oral capsule of AVP-786 twice daily (dose 2)
- An oral capsule of AVP-786 twice daily (dose 3)
Neither the participant nor their 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 the study is to evaluate the efficacy and safety, and tolerability 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 will be asked to complete some laboratory tests (e.g. blood test, ECG) to evaluate the side effects (it refers to unfavourable signs, symptoms or diseases temporally associated with the use of the drug tested in the study)
- Participants will also need to complete some other tests to evaluate their cognition, thinking skills, behaviour, agitation and quality of life (e.g. MMSE, CMAI, NPI, DEMQOL)
- Complete questionnaires to measure the general level of daytime sleepiness (ESS) and access/monitor over time the core phenomena of suicidality (S-STS).
Further information on the procedures, tests and number of visits can be obtained from the study team.
