What You Need to Know Before You Apply

What is the purpose of this trial?

This trial is testing a medication called AVP-786 on individuals who have taken part in previous studies. The goal is to see if this medication can help with their conditions over time.

Will I have to stop taking my current medications?

The trial does not specify if you need to stop taking your current medications, but you cannot have used NUEDEXTA® in the 2 weeks before starting the trial.

Is AVP-786 safe for humans?

AVP-786, which is similar to AVP-923 (Nuedexta®), was well tolerated in a study with over 200 patients with Alzheimer's disease, showing it is generally safe for humans.12345

How is the drug AVP-786 different from other treatments for agitation in Alzheimer's disease?

AVP-786 is unique because it combines deuterated dextromethorphan with quinidine, which helps the drug stay in the body longer and penetrate the brain more effectively. Unlike other treatments, it has been granted fast-track designation by the FDA, indicating its potential as a promising new option for managing agitation in Alzheimer's disease.12367

What data supports the effectiveness of the drug AVP-786 for agitation in Alzheimer's disease?

AVP-786 is similar to AVP-923, which reduced agitation in Alzheimer's patients and was well tolerated in a study with over 200 participants. The FDA has also fast-tracked AVP-786, indicating its potential based on existing data.12458

Are You a Good Fit for This Trial?

This trial is for patients with Alzheimer's-related dementia who've completed certain earlier studies (15-AVP-786-301, 302, 12-AVR-131, or 17-AVP-786-305). They should be experiencing moderate to severe agitation and have a specific level of cognitive function. It's open to out-patients or those in assisted living/nursing homes but not for individuals at high risk of falls or with other serious health issues that could affect safety results.

Inclusion Criteria

Participant has successfully completed Studies 15-AVP-786-301, 15-AVP-786-302, 12-AVR-131, or 17-AVP-786-305. (Note: A delay in enrollment may include delays associated with COVID-19 restrictions.)
If you sign up late, you must have a specific score on a test that checks your memory and thinking abilities.

Published Research Related to This Trial

AVP-786, a new investigational drug combining deuterated dextromethorphan and quinidine, shows promise for treating agitation in Alzheimer-type dementia, with a favorable pharmacokinetic profile that enhances its effectiveness and safety.
Previous studies, including a phase II trial with over 200 patients, indicated that AVP-923 (a related compound) effectively reduced agitation and was well tolerated, supporting the potential of AVP-786 in ongoing phase III trials.
AVP-786 for the treatment of agitation in dementia of the Alzheimer's type.Garay, RP., Grossberg, GT.[2017]
In two 12-week studies involving a total of 703 patients with agitation in Alzheimer's dementia, brexpiprazole at a dose of 2 mg/day showed significant improvement in agitation symptoms compared to placebo, indicating its efficacy in this patient population.
Brexpiprazole was generally well tolerated, with most treatment-emergent adverse events being mild to moderate, although headaches and insomnia were reported more frequently than with placebo.
Efficacy and Safety of Brexpiprazole for the Treatment of Agitation in Alzheimer's Dementia: Two 12-Week, Randomized, Double-Blind, Placebo-Controlled Trials.Grossberg, GT., Kohegyi, E., Mergel, V., et al.[2021]
In a case series involving 20 patients with agitation due to Alzheimer's disease, 65% responded positively to low-dose divalproex treatment, indicating its potential efficacy in managing behavioral disturbances.
The study also found that 25% of patients experienced adverse events, suggesting that while low-dose divalproex can improve behavior, there is still a risk of side effects that needs to be monitored.
