There are currently no FDA approved disease-modifying treatments available for frontotemporal dementia (FTD), and symptomatic treatments only provide limited benefit for patients. Recent scientific advances have provided an increased understanding of pathogenic mechanisms underlying FTD and are driving the development of potential disease-modifying therapies. The Alzheimer’s Drug Discovery Foundation (ADDF) and The Association for Frontotemporal Degeneration (AFTD) seek to accelerate this progress by supporting innovative small molecule and biologic (antibodies, oligonucleotides, peptides, gene therapy etc.) drug development programs for FTD through this request for proposals (RFP).

Association for Frontotemporal Degeneration

Deadlines

Must be received by 5:00 pm ET on the deadline date.

Letter of Intent: May 13th, 2024
Invited Full Proposal: July 22nd, 2024

Average Duration

One year with potential for follow-on funding.

Average Award

$300,000-$350,000 based on stage and scope of research. Slightly higher budgets can be considered. Please contact us for review and approval.

 

Eligibility

Funding is open to researchers and clinicians in the U.S. and worldwide working in:

  • Academic medical centers and universities or nonprofits. Industry partnerships are encouraged.
  • Biotechnology companies that demonstrate a clear need for nonprofit funding. Existing companies and new spinouts are both eligible.

Because of our Venture Philanthropy model, all funding provided by the ADDF is through mission-related investments (MRIs) that require return on investment based upon scientific and/or business milestones. Return on investment can include equity, convertible notes or royalties and are determined on a case-by-case basis.

Please review our Funding Policies before applying.


Funding Priorities

The RFP supports:

  • Lead optimization of novel disease-modifying compounds, including medicinal chemistry refinement and in vitro ADME.
  • In vivo testing of novel lead compounds, biologics, vaccines, or repurposed drug candidates in relevant animal models for pharmacokinetics, dose-range finding, target engagement, in vivo efficacy, and/or preliminary rodent tolerability studies.

This RFP does NOT support target identification, target validation, assay development, high-throughput and high-content screening. IND-enabling work is supported through ADDF’s Drug Development RFP.


Drug Targets

Current target areas of interest include, but are not limited to:

  • Inflammation
  • Proteostasis
  • Autophagy
  • Epigenetics
  • Genetic Causes of Disease (C9ORF72, MAPT, GRN, etc.)
  • Misfolded proteins (TDP-43, tau, FUS etc.)
  • Mitochondria & Metabolic Function
  • Neuroprotection
  • Synaptic Activity & Neurotransmitters
  • RNA metabolism and splicing
  • Stress granule formation and liquid-liquid phase separation

Other novel targets or pathways that are supported by compelling evidence that demonstrate a rational biological connection to FTD are encouraged.


Expectations

Novel Drugs

The strongest applications will test a compound that has met many or all of the following criteria:

  • Chemical structures of hits and leads have been assessed for structural liabilities
  • Novel composition of matter patents have been filed or plans to generate novel composition of matter intellectual property (IP) have been developed

Repurposed/Repositioned Drugs

The strongest applications will test a repurposed or repositioned drug that has met many or all of the following criteria:

  • The known side effects of the drug and how well they would be tolerated by the intended FTD population have been evaluated
  • A supplier has been identified that will provide sufficient quantities of the drug or compound to complete the study aims
  • Plans to develop novel IP around the repurposing/repositioning strategy have been considered

Preclinical Efficacy Studies

Applications that include preclinical efficacy studies should:

  • Provide data demonstrating blood-brain barrier penetration (if the intended target is in the CNS)
  • Justify dose, route of administration, and regimen with in vivo PK/PD data. If this data is not yet available, a PK/PD study aim should be included in the proposal
  • Include measures of target engagement in the proposed animal study design
  • Include measures to assess off-target effects with the potential to interfere with behavioral outcome measures (e.g., sedation)

Applicants are encouraged to follow the recommendations outlined in Shineman (2011), Roberson (2012), Vernay (2015), Snyder (2016), Wong (2018), Soloman (2018), and Giong (2021) when developing the animal study design.


Evaluation

All proposals will be evaluated for:

  • Rational biological connection of the target to the disease pathophysiology
  • Strength of the scientific approach and supporting preliminary data
  • Feasibility of specific aims and strength of the research design and methodology, including justification of the proposed model for efficacy studies, particularly its relevance to FTD clinical phenotypes
  • Appropriate data analysis strategy
  • Qualifications and experience of the Investigative team including adequacy of resources and environment
  • Appropriateness of the project budget

Targets

The following criteria will be used to assess the proposed drug target(s):

  • Is there human genetic evidence linking the target to FTD disorders? Targets without a defined genetic link will also be considered.
  • Is the target expressed in disease-relevant regions of the brain (or where applicable, in the periphery) in humans and/or animal models?
  • Are there changes in target mRNA/protein expression or activity in human disease specimens from FTD disorders, and do they correlate with disease severity and cognitive or behavioral functions?
  • Does genetic and/or pharmacological manipulation of the target in disease-relevant in vitro (e.g., primary cultured neurons/glia or cells derived from patient iPSCs) or in vivo models alter disease phenotypes?
  • Are there direct measures of target engagement that can be used experimentally and eventually in humans?
  • Is there a rational biomarker strategy?
  • How is the target more compelling than other related targets that have been tested for FTD disorders?

If the molecular target is unknown, the strength of the evidence for the mode of action and its link to disease pathophysiology will be evaluated. The applicant should summarize the existing evidence in the proposal.


Animal Models

There are numerous available models of dementia, including transgenic models with a host of different transgenes expressed alone or in combination. Each of these models reflect different aspects of disease, which vary from the number and types of phenotypes observed to their onset and severity; however, none of these models recapitulate all aspects of human disease. Instead, the appropriate model can provide valuable information on how the therapeutic engages with its target and its ability to modify phenotypes related to its mode of action.

Reviewers will evaluate the rationale for the proposed animal model using the following criteria:

  • How well characterized is the animal model? Has it been characterized in the applicant's or collaborator's lab, or is there historical control data available from the contract research organization (CRO) that will run the study?
  • Does the model mimic FTD-relevant pathology and FTD cognitive/behavioral symptoms (e.g., apathy, disinhibition, social disinterest, perseverative behavior, overeating/carbohydrate craving) or motor deficits (instability, gait changes, maintain balance, strength, reflexes, coordination, unilateral motor changes, decline in overall mobility)?
  • Does the model exhibit the appropriate phenotype(s) to measure target engagement (e.g. a drug intended to reduce pro-inflammatory cytokines in the brain should be tested in a model shown to exhibit elevated pro-inflammatory cytokine levels)?
  • Does the model exhibit other phenotypes relevant to the mode of action that can be measured as secondary outcomes (e.g. abnormal protein accumulation, synaptic changes, neuronal loss, cognitive defects, etc.)?
