BPSD WORKING GROUP PROPOSAL ABSTRACT

Objectives: This working group is being convened to focus on the methodological challenges

facing the development of treatments for the Behavioral and Psychiatric Symptoms of Dementia

(BPSD). This group was in part stimulated by the EMA Alzheimers Disease Workshop.

Convey critical importance of treating BPSD, i.e., Apathy as a means to improve patient QOL,

extend patients stay in their home environment; improve overall

Review of lessons learned from ongoing and prior clinical trials for BPSD.

Proposing innovative trials designs and regulatory acceptance;

Managing intrinsic variability of symptoms;

Evolving AD diagnostic and biomarker approaches

Staging of illness and impact on symptoms, response, study design;

Regulatory perspectives

Workshop Deliverables and Action items/Steps to move the field forward

Extend collaboration with ISTAART PIA; review activities of PIA and FRS for AAIC;

Finalize program for 2017 Autumn meeting in Paris

Consider establishing WG team to:

look at challenges and lessons learned from past/current clin trials to treat BPSD; create

review article, road map, and/or report for presentation at ISCTM or other meetings

Session 4: Addressing challenges in the drug development of

behavioral and psychological symptoms in dementia

The constellation of symptoms/syndromes comprising BPSD (NPS) present

a challenge at all levels of health care, from unmet patient and caregiver

needs, to drug discovery, to clinical trials, as well as to regulatory pathways.

A review of the lessons learned from recent efforts to develop drug

treatments for Agitation or Psychosis in neurodegenerative disorders will be

applied to enable methodological discussions on the development of

treatments for Apathy in Alzheimers Disease (AD). We will explore how

Apathy symptoms and potential biomarkers evolve across the spectrum

from Mild Brain Impairment (MBI) to Mild Cognitive Impairment (MCI) to AD.

What are accepted diagnostic criteria for Apathy in AD and will disease

progression affect treatment targets and assessment tools? How should

pseudo-specificity be addressed in identifying and assessing apathy?

Differentiation from depression and relationship with changes in cognition

will be discussed. What are the challenges of conducting translational and

proof of concept work in patients with Apathy in MBI/MCI? The application of

neurocircuitry strategies and other biomarker approaches in early drug

development could de-risk POC. Regulatory considerations of approaches

and methodologies to improve the likelihood of meaningful signal detection

and acceptable registration trials will be discussed.

STRATEGIES FOR FDA ENGAGEMENT AND

COMMENTARY IN PARIS SYMPOSIUM

SC/EC suggested a few strategies:

Pre-recorded comments from a key FDA Regulator on the path forward for Apathy

Question/Answer interview, also pre-recorded with symposium leader, incorporating

content from the presentations (will require advance input from presenters)

Less likely, more complex, live videoconferencing. Session on Saturday, runs

afternoon to evening EST

Available by phone to provide comments or Q/A

Would also ask Valentina, Luca, and/or Karl to highlight in their comments that describe

areas of communication and engagement between EMA and FDA

Background: The Need for BPSD

medicines

No approved treatments for BPSD

Lack of required studies to support efficacy of antipsychotics for BPSD or psychosis of dementia

Many negative and some positive registrational studies what can we learn?

Non-approved use of existing antipsychotics (20-50%1) and other sedative medications have serious safety concerns (increased mortality, CVAs, drowsiness, falls, increased morbidity)

Class labelling for atypical antipsychotics (weight, type 2 diabetes, metabolic syndrome and hyperlipidemia)

BPSD are highly prevalent and a leading cause of institutionalization

Clinicians and regulators recognize the need for newer safer and effective treatments for BPSD
