Funding Opportunity Purpose

The goal of this Notice of Funding Opportunity(NOFO) is to identify, in animals, in vivo neurophysiological and behavioral measures for use as assays in the early screening phase of treatment development. This NOFO will support efforts to optimize and evaluate measures of neurophysiological and behavioral processes that may serve as pharmacokinetic/pharmacodynamic (PK/PD) markers of neural processes of clinical interest based on available knowledge of the neurobiology of mental illnesses. The screening assays developed from this NOFO are expected to build upon systems neurobiology and clinical neuroscience to enhance the scientific value of preclinical animal data contributing to a therapeutic development pipeline in which treatment candidates and therapeutic targets can be evaluated for their ability to impact neurobiological mechanisms of potential clinical relevance to mental illnesses.

The objectives of this NOFO will be accomplished by supporting basic neuroscience aimed at improving the efficiency and scientific value of the therapeutic development pipeline by advancing the discovery of in vivo physiological and behavioral measures reflecting circuit engagement as tools for early phase target validation and therapeutic screening for mental illness treatment development. The efforts supported by this initiative focus on measures in animals as a first step in generating translational assay measures that are adaptable across early therapeutic screens in animals to evaluation in humans. The NOFO may be considered a prequel to build a suite of assays that are evaluated in future projects for coherence of assay performance between the preclinical species and healthy humans. In summary, this NOFO will support efforts to improve the tool kit of assays available for early phase testing of novel therapeutic agents by incorporating measures proximal to neural systems that impact mental health.

Section I. Notice of Funding Opportunity Description

Background and Research Objectives

Despite large investments by pharmaceutical and biotech industries, the last 20 years have yielded few novel treatments to address unmet needs of individuals suffering with mental illnesses. Multiple factors have contributed to the low success rate, including insufficient understanding of disease pathophysiology and the basis for heterogeneity in presentation and treatment response of patients within categorical diagnoses. The NIMH supports efforts such as the Research Domains Criteria (RDoC) project to transform diagnostics by promoting research that extends beyond the current symptom-based diagnostic categories (i.e., Diagnostic and Statistical Manual, DSM) to identify functional domains whose disruption contributes significantly to disability across diagnoses. However, RDoC was designed to provide a context to examine functional domains and relevant neurobiology in humans, not in animals. While clinical neuroscience advances our understanding of circuit disruptions driving behavioral deficits in humans, the need for comparable efforts in basic neuroscience has become evident, particularly across the therapeutic development pipeline where behavioral screens in animals often contribute to the selection of lead candidates for the development of novel treatments for mental illnesses. The goal of this NOFO is to address this gap by supporting the initial development and testing of innovative neurophysiological and behavioral measures that have the potential to serve as translational screening assays in preclinical species.

The poor predictive value of current preclinical screening model systems in therapeutic development for neurological and mental disorders is well recognized by the pharmaceutical industry and was the topic of a high profile workshop (see National Academies of Sciences, Engineering and Medicine report, Therapeutic Development in the Absence of Predictive Animal Models of Nervous System Disorders: Proceedings of a Workshop). Commonly used batteries of behavioral assays in rodents such as the forced swim test, tail suspension test, elevated plus maze, novelty induced suppression of feeding, sucrose preference, open field activity test, and reversal of drug-induced hyperlocomotion or grooming are useful in some contexts, such as addressing effects of novel ligands on brain penetrance and dose response. However, these measures do not reflect specific neural processes or predict efficacy. Relationships between these measures in animals and behavioral deficits or neural activity irregularities in patients is unknown.

Technical advances in neuroscience, including those generated through the Brain Research Through Advancing Innovative Neurotechnologies (BRAIN) Initiative, now provide tremendous opportunities to understand the functional impact of cell and circuit diversity and identify novel therapeutic targets. Still, while the neurobiology underlying target identification has advanced, neuroscience-based approaches to screen potential targets and treatment candidates in the therapeutic development pipeline have not kept pace. The current NOFO is built on the premise that it is possible to develop neurophysiological and behavioral measures in animals that mirror a subset of brain activities and functional domains suggested by clinical neuroscience to impact mental health and disability, here defined as potentially “clinically relevant”. To advance such measures as assays for treatment development, this NOFO encourages applications aimed at addressing three specific goals; 1) identification and optimization of measures that reflect clinically relevant brain processes that are potentially conserved between preclinical species and humans, 2) evaluation of the sensitivity and selectivity of the potential measures as screening assays by examining their performance in response to perturbations such as drugs, and 3) testing the role of the brain pathways hypothesized to underlie the physiological and/or behavioral assay measure. Completion of these goals is expected to unveil novel, research-based physiological and/or behavioral assays that are poised for cross validation against results of similar measures in humans and then potential use as preclinical assay measures in a treatment development pipeline for mental illnesses. Thus, while human testing is not a component of this NOFO, the measures to be developed in animals through this NOFO should be designed so the coherence, or lack of concurrence, of the assay performance across species to humans can be assessed in future projects. In this way, assays developed here may be considered the preclinical prequel to subsequent projects aimed at evaluating the assays for coherence of performance between the preclinical species and healthy humans.

Research Scope

The NOFO supports the initial stages in the development, optimization, and evaluation of novel in vivo measures as potential assays in early (pre-first in human) screening of therapeutic candidates. Assays may include neurophysiological measures and may include behavioral measures. Key considerations are listed below but at a minimum, measures should be amenable to study in live animals and in future studies in humans, and they must be innovative.

Priority will be given to applications that include all three of the following phases:

  1. Optimization, in animals, of novel, predominantly non-invasive neurophysiological or behavioral measures reflecting activity of clinically relevant brain processes or functional domains that are disrupted within or across mental illnesses. Optimization should focus on mirroring testing parameters or measures used in human experiments where human assays exist or developing tests that have potential value for future translation to humans.
  2. Evaluation of the performance of the physiological or behavioral measures using FDA-approved drugs or other interventions with demonstrated effects on the targets, in a dose ranging study that includes pharmacokinetic/pharmacodynamic (PK/PD) readouts.
  3. Mechanistic testing of brain processes and/or circuits proposed as key drivers of the neurophysiological or behavioral assay measures. For example, a study might include optogenetic or chemogenetic approaches to manipulate specific circuits in combination with in vivo electrophysiological measures to verify circuits contributing to specific EEG power spectral changes elicited by a cognitive challenge. Studies are expected to include a subset of studies that address the relationship between brain activity measures and changes in the physiological or behavioral assay measures in response to the same drugs or perturbations evaluated in the assay optimization stage.

This NOFO aims to stimulate the development of in vivo assays to address translational gaps in treatment development for mental illnesses. Support will be provided for assay development efforts in animals that propose quantitative measures of neurophysiological and/or behavioral processes where there is reasonable evidence to suggest that measure is a potential contributor to functional deficits of individuals with mental illnesses (e.g., cognitive function, impulsivity, motivation, etc.).

Examples of relevant neurophysiological and/or behavioral measures for development and evaluation as assays include, but are not limited to:

  • Spectral EEG or MEG to assess brain rhythms within different frequencies.
  • Measures that tap into fundamental processes that are disrupted within or across mental illnesses such as aspects of vigilance, attention, neurophysiological measures of neural plasticity, or affect regulation.
  • Measures relevant to anhedonia that can be assessed in animals and humans such as reward learning, cognitive effort during learning, measures of wanting versus liking, etc.
  • Measures relevant to impulsivity such as delay discounting, behavioral inhibition.
  • Measures that tap into neural circuit activity linked to specific cognitive domains. For example, the CNTRICS program identified constructs across six cognitive systems relevant to schizophrenia and selected tasks from cognitive neuroscience that measure the constructs and the CNTRACS initiative extended those measures (goal maintenance, relational encoding, gain control, visual integration).
  • Prefrontal cortical top-down inhibitory control over subcortical and brainstem systems that regulate autonomic function (brain noradrenergic hyperfunction, electrodermal response, pupillometry).
  • Measures of sleep physiology (sleep spindle characteristics, sleep microstructure) relevant to mood and cognitive function. Note that studies of circadian rhythmicity mechanisms per se are not appropriate for this NOFO.
  • Measures in awake behaving animals relevant to human functional or molecular imaging (fMRI or MRS).
  • Additional innovative measures are encouraged including the use of novel tools or methods arising from the BRAIN Initiative®.
  • Computational approaches connecting behaviors with circuit functions are encouraged. NIMH is particularly interested in new computational theories of complex behaviors able to link multiple behavioral (and circuit) parameters, tracked over time to make predictions on potentially back-translatable (animal-to-humans) behavioral outcomes.

Mechanistic testing of underlying brain pathways will be tailored to the proposed assay measure. For example, studies might examine whether specific changes in dopamine signaling to striatum or prefrontal cortex reliably predict speed or accuracy of reward contingency learning. These studies are critical for advancing a new generation of in vivo assays for therapeutic development that are grounded in a clinically-meaningful neurobiological context.

The main emphasis must be on developing novel, clinically relevant measures as assays. While the neurophysiological or behavioral measures may not be innovative by themselves, their inclusion in a therapeutic development pipeline must be novel.

Since this work is expected to identify and optimize novel assay measures that can subsequently be compared with measures in healthy humans, proposed neurophysiological and behavioral assay measures should have analogs that can be performed in healthy humans.

While neurophysiological measures such as event-related potential (ERP) may be useful for refining critical temporal parameters of an assay, they have insufficient specificity to assess effects across trials. Studies proposing EEG measures as assays should focus on frequency band measures for this NOFO.

Measures should be innovative in relation to published relevant literature. For example, assays of plasticity mechanisms could focus on novel neurophysiological measures. Many behavioral readouts of learning and memory are well established and already sufficiently represented in the NIMH portfolio, particularly for contextual versus cued fear learning.

Applications Not Responsive to this NOFO

The following will be considered not responsive and will not be reviewed:

  • Studies involving human subjects.
  • Development or inclusion of animal models "of" mental disorders. Projects should adhere to the recommendations in NOT-MH-19-053 Notice of NIMH’s Considerations Regarding the Use of Animal Neurobehavioral Approaches in Basic and Pre-clinical Studies, as well as the Recommendations of the NAMHC Workgroup on Genomics.
  • Broad batteries of behavioral tests or clinical battery testing.
  • Behavioral assays without inclusion of measures of associated brain processes and/or neural circuits.
  • Studies aimed solely at developing measures of circadian rhythmicity or clock regulatory mechanisms as assays.
  • Cell culture or in vitro assay measures.
  • Hypothesis testing beyond evaluation of the relationship of the neurophysiological or behavioral measures to specific circuits. For example, studies focused primarily on testing brain systems underlying functional domains, pathophysiology of disease, or treatment response are not appropriate.
  • Studies aimed primarily at evaluating novel therapeutic targets or treatment candidates.

Milestones

All projects must propose a timeline for completion of the required components of assay development, including (1) assay measure optimization, (2) evaluation of assay performance, and (3) mechanistic testing. If more than one measure is proposed for optimization, the timeline must include plans for optimization of each measure. An additional milestone should outline plans and a timeline for dissemination of results, regardless of outcome.

Specific Aims: Provide the overall goals for the entire application. The Specific Aims section should include distinct Aims for each of the three phases (assay optimization, performance evaluation, and mechanistic testing).

Research Strategy: Organize the Research Strategy in the subsections identified below.

Applicants should describe the three phases within these subsections as described, including milestones for each phase.

Factor 1. Importance of the Research

Significance:

  • Discuss how the proposed measure(s) of neurophysiological or behavioral processes address a translational gap including how they relate to brain activities and functional domains suggested by clinical neuroscience to impact mental health and disability.
  • Detail how do the proposed measures relate to currently available measures used to assess functional domains in humans.
  • Describe how the results will add value to a therapeutic development pipeline regardless of outcome.

Innovation:

  • Explain how the project offers a novel approach to evaluating potential new treatments for mental illnesses.
  • If similar types of measures are already in common practice in a preclinical treatment development pathway, explain why the proposed approach would be expected to provide important new information or a benefit over existing measures.

Factor 2. Rigor and Feasibility

Approach: This section should cover the application as a whole as well as the three phases with the appropriate headers within the text.

Overall Approach:

  • Justify the choice of measure(s), including a brief description of evidence that the measures have potential to either directly or indirectly assess activity or function within the same targeted circuits or physiological processes in both the preclinical species and humans.
  • Explain the rationale behind the choice of preclinical species, assays, and endpoints for all studies.
  • Provide evidence of feasibility to perform the measurements and manipulations in both preclinical species and humans (the latter in future studies).
  • Include discussion of evidence indicating how the planned measures/manipulations are relevant to key neural circuits/processes that are disrupted in mental disorders and with potential clinical benefit if corrected.
  • Describe the research team's approach toward selecting, optimizing and evaluating the assays.
  • Describe goals for each of the three phases:
    • For phase 1, optimization: clearly describe studies aimed at measure optimization to approximate measures that are, or could be, performed in humans. Include strategies for addressing barriers that may arise in the course of optimization to facilitate future head to head comparisons with comparable measures in humans. For example, if the goal is to advance task driven EEG measures in rodents, describe studies aimed at improving signal to noise or determining optimum electrode placement.
    • For phase 2, performance evaluation: detail how performance of the physiological or behavioral measure(s) will be evaluated as potential assay(s) using FDA approved drug(s) or other intervention with demonstrated actions on the CNS target, in a dose ranging PK/PD study. Describe the rationale for the study design, including dose range, PK sampling, route, and timing of the drug in relation to testing. For example, detail if dose selection is based on brain target occupancy, how measurements are timed for known Cmax, etc.
    • For phase 3, mechanistic testing: detail methods to be used to test the involvement of hypothesized circuits, including procedures for both directly modifying the circuits and recording effects on circuit activity during simultaneous measurement of the physiological or behavioral measure. For example, a study might include optogenetic or chemogenetic approaches to manipulate specific circuits in combination with in vivo electrophysiological measures to verify circuits contributing to specific EEG power spectral changes elicited by a cognitive challenge.
  • Applications must also include a subset of experiments evaluating the relationship between brain activity changes and physiological/behavioral assay measures in response to the same intervention evaluated in the performance evaluation stage.
  • Applications are strongly advised to provide alternate strategies should results suggest the tested circuit is not critical for the measure.
  • Include enough details to allow reviewers to evaluate the rigor of the experimental design. Describe the study design in detail, including the strain, age, and sex of animals, power analyses and associated assumptions for the determination of sample size, statistical handling of the data, procedures used for addressing sex as a biological variable, blinding and randomization.
  • Describe plans for data analysis and interpretation including the PK/PD relationship and what would constitute a go/no-go decision for further measure development, including later tests for cross-species conservation of the measure, and implementation in a therapeutic discovery pipeline.
  • Include a detailed Results and Interpretation section that outlines how results will be evaluated and a timeline for dissemination of results to the broader research community.

Milestones:

Specific goals and feasibility milestones must be clear and linked to the timeline for completing the studies in no more than 5 years. Separate milestones should be proposed for each of the 3 study components for assay optimization and testing. The milestones should be quantifiable and scientifically justified. If more than one measure is proposed, separate milestones should be provided for each. Required milestones are expected to address assay measure optimization (1), evaluation of assay performance (2), and mechanistic testing (3). An additional milestone should outline plans and a timeline for dissemination of results, regardless of outcome.

Resource Sharing Plan: Individuals are required to comply with the instructions for the Resource Sharing Plans as provided in the How to Apply- Application Guide.

Other Plan(s): 

All instructions in the How to Apply-Application Guide must be followed, with the following additional instructions:

  • All applicants planning research (funded or conducted in whole or in part by NIH) that results in the generation of scientific data are required to comply with the instructions for the Data Management and Sharing Plan. All applications, regardless of the amount of direct costs requested for any one year, must address a Data Management and Sharing Plan.

While it is understood that many of the approaches and early data generated through this NOFO will be at an early proof-of-concept stage, a central goal is to contribute a toolset that facilitates the adoption of robust, experimentally based measures in the early phases of a therapeutic development pipeline for mental illnesses. Regardless of study outcomes or publication status, the experimental protocols and data generated through this NOFO will be valuable to the research community by indicating assay measures with ambiguous relationships to brain circuits as well as those poised for assessment of potential predictive value in future cross species comparisons.

Accordingly, all applications are expected to include a detailed Data and Experimental Protocol sharing plan that specifies how data will be shared and who will be responsible for managing sharing of all protocols and data, consistent with achieving the goals of this program.

Applicants must include the following key elements:

  • Description of how protocols and data will be shared as well as schedule/timeline for sharing data.
  • Detailed plans on how data will be made broadly available.

Section V. Application Review Information

1. Criteria

Only the review criteria described below will be considered in the review process. Applications submitted to the NIH in support of the NIH mission are evaluated for scientific and technical merit through the NIH peer review system.

Overall Impact

Reviewers will provide an overall impact score to reflect their assessment of the likelihood for the project to exert a sustained, powerful influence on the research field(s) involved, in consideration of the following scored review criteria and additional review criteria (as applicable for the project proposed). An application does not need to be strong in all categories to be judged likely to have a major scientific impact.

Scored Review Criteria

Reviewers will evaluate Factors 1, 2 and 3 in the determination of scientific merit, and in providing an overall impact score. In addition, Factors 1 and 2 will each receive a separate criterion score. 

 

Significance

  • Evaluate the importance of the proposed research in the context of current scientific challenges and opportunities, either for advancing knowledge within the field, or more broadly. Assess whether the application addresses an important gap in knowledge in the field, would solve a critical problem, or create a valuable conceptual or technical advance.
  • Evaluate the rationale for undertaking the study, the rigor of the scientific background for the work (e.g., prior literature and/or preliminary data) and whether the scientific background justifies the proposed study.

Innovation

  • Evaluate the extent to which innovation influences the importance of undertaking the proposed research. Note that while technical or conceptual innovation can influence the importance of the proposed research, a project that is not applying novel concepts or approaches may be of critical importance for the field.
  • Evaluate whether the proposed work applies novel concepts, methods or technologies or uses existing concepts, methods, technologies in novel ways, to enhance the overall impact of the project.

Specific to this NOFO

  • Evaluate whether the proposed assay measure taps into a brain process of relevance to mental illnesses, i.e., whether there is a reasonable chance that they assay measure could show a difference in patients with mental illnesses. 
  • Evaluate the likelihood that completion of the research objectives could lead to a novel assay that enables more biologically linked predictions of effects of novel treatment candidates from preclinical species to humans.
  • Evaluate the strength of the rationale to support the choice of manipulation(s) for evaluating performance of the assay measure(s). 
  • Evaluate the novelty of the proposed approach for screening new treatments in a preclinical therapeutic development pipeline. 
 

 

Approach

  • Evaluate the scientific quality of the proposed work. Evaluate the likelihood that compelling, reproducible findings will result (rigor) and assess whether the proposed studies can be done well and within the timeframes proposed (feasibility).

Rigor:

  • Evaluate the potential to produce unbiased, reproducible, robust data.
  • Evaluate the rigor of experimental design and whether appropriate controls are in place.
  • Evaluate whether the sample size is sufficient and well-justified.
  • Assess the quality of the plans for analysis, interpretation, and reporting of results.
  • Evaluate whether the investigators presented adequate plans to address relevant biological variables, such as sex or age, in the design, analysis, and reporting.
  • For applications involving human subjects or vertebrate animals, also evaluate:
    • the rigor of the intervention or study manipulation (if applicable to the study design).
    • whether outcome variables are justified.
    • whether the results will be generalizable or, in the case of a rare disease/special group, relevant to the particular subgroup.
    • whether the sample is appropriate and sufficiently diverse to address the proposed question(s).
  • For applications involving human subjects, including clinical trials, assess the adequacy of inclusion plans as appropriate for the scientific goals of the research. Considerations of appropriateness may include disease/condition/behavior incidence, prevalence, or population burden, population representation, and/or current state of the science.

Feasibility:

  • Evaluate whether the proposed approach is sound and achievable, including plans to address problems or new challenges that emerge in the work. For proposed studies in which feasibility may be less certain, evaluate whether the uncertainty is balanced by the potential for major advances.
  • For applications involving human subjects, including clinical trials, evaluate the adequacy and feasibility of the plan to recruit and retain an appropriately diverse population of participants. Additionally, evaluate the likelihood of successfully achieving the proposed enrollment based on age, racial, ethnic, and sex/gender categories.
  • For clinical trial applications, evaluate whether the study timeline and milestones are feasible.

Specific to this NOFO

  • Evaluate the extent to which the proposed experiments will build innovative and useful preclinical assays and approaches in a therapeutic development pipeline. 
  • Evaluate how effectively the proposed studies will evaluate relationships between brain activity changes and physiological/behavioral assay measures. 
  • Evaluate the justification for the choice of neurophysiological and/or behavioral measures in terms of 1) relevance to functional deficits in humans with mental illnesses and 2) feasibility to perform the measure in animals in the current project and in humans in future studies. 
  • Evaluate the strength of the rationale that supports conservation of the proposed brain processes under investigation across humans and the preclinical species. Evaluate whether the project will generate the data necessary to determine whether the brain processes being studied can be directly compared with measures in humans in the future.
  • Evaluate how clear and justified the go/no-go decisions are for enabling further measure development and implementation in a therapeutic discovery pipeline.
  • For phase 2 evaluation studies: 1) evaluate how effectively the proposed experiments will test the involvement of hypothesized circuits in driving the physiological/behavioral assay measures; 2) evaluate the appropriateness of the proposed drug/intervention, including dose range, route, PK sampling, and timing of intervention relative to testing; 3) evaluate whether dose selection is based on brain target engagement measures such as receptor occupancy; and 4) evaluate whether the measurements are based on known drug Cmax.
 

 

Investigator(s)

Evaluate whether the investigator(s) have demonstrated background, training, and expertise, as appropriate for their career stage, to conduct the proposed work. For Multiple Principal Investigator (MPI) applications, assess the quality of the leadership plan to facilitate coordination and collaboration.

Environment

Evaluate whether the institutional resources are appropriate to ensure the successful execution of the proposed work.

Additional Review Criteria

As applicable for the project proposed, reviewers will consider the following additional items while determining scientific and technical merit, but will not give criterion scores for these items, and should consider them in providing an overall impact score.

 

For research that involves human subjects but does not involve one of the categories of research that are exempt under 45 CFR Part 46, evaluate the justification for involvement of human subjects and the proposed protections from research risk relating to their participation according to the following five review criteria: 1) risk to subjects; 2) adequacy of protection against risks; 3) potential benefits to the subjects and others; 4) importance of the knowledge to be gained; and 5) data and safety monitoring for clinical trials.

For research that involves human subjects and meets the criteria for one or more of the categories of research that are exempt under 45 CFR Part 46, evaluate: 1) the justification for the exemption; 2) human subjects involvement and characteristics; and 3) sources of materials. For additional information on review of the Human Subjects section, please refer to the Guidelines for the Review of Human Subjects.

 

When the proposed research includes Vertebrate Animals, evaluate the involvement of live vertebrate animals according to the following criteria: (1) description of proposed procedures involving animals, including species, strains, ages, sex, and total number to be used; (2) justifications for the use of animals versus alternative models and for the appropriateness of the species proposed; (3) interventions to minimize discomfort, distress, pain and injury; and (4) justification for euthanasia method if NOT consistent with the AVMA Guidelines for the Euthanasia of Animals. For additional information on review of the Vertebrate Animals section, please refer to the Worksheet for Review of the Vertebrate Animals Section.
