Section I. Notice of Funding Opportunity Description

Purpose and Background

Through this Notice of Funding Opportunity, (NOFO), NIMH wishes to stimulate research in the discovery and development of novel screening assays for the discovery of validated hits that can be used in future drug discovery/development efforts for identifying potential drug candidates for the treatment of mental illness. For purposes of this initiative, a “hit” is defined as a compound that has the desired activity in a compound screen and whose activity is confirmed upon retesting in orthogonal assays.

Stages of discovery research covered by this NOFO include 1) assay development; 2) primary screen implementation to identify initial screening hits (high throughput target-focused screens, or moderate throughput screens); and 3) hit validation using a series of assays and initial medicinal chemistry inspection to prioritize the hit set.

Assessment of the reasons for failures of small molecule therapeutic agents in the clinic points to several areas for improvement of the drug discovery and development process that are pertinent to this NOFO:

  • First, increased rigor in target identification is necessary. For instance, whether prior studies of the selected target were adequately controlled and powered are important considerations. Were cell lines verified, plasmids sequenced, and protein reagents tested for contaminants?
  • Second, reproducibility of the proposed primary assay should be carefully considered because this assay is often the basis for assessing not only initial hits but also for iteratively assessing optimized hits during structure-activity relationship (SAR) studies. Development of primary screening assays that test a key biological function of the target of interest are likely to yield hits of increased relevance. In this respect, phenotypic screens have had a resurgence.
  • Third, a hit validation scheme or “critical path” that includes orthogonal assay(s) to eliminate false positives, as well as a series of assays in diverse biological systems with diverse read-outs, particularly including assays that model human disease, is likely to yield hits of increased relevance.
  • Fourth, the inclusion of skilled synthetic and/or medicinal chemists to assess the validity of the hit chemotypes to eliminate PAINS (pan-assay interference compounds) or other undesirable chemotypes. 

Research Scope

Projects covered by the NOFO should focus on the following stages of the discovery research:

1) Assay development

2) Primary screen implementation

3) Hit validation

Areas to be considered for each stage are described below and given in greater detail in Section IV (Application and Submission Information, PHS 398 Research Plan).

1. Assay Development

This NOFO supports implementation of innovative biological, biophysical or cell-based assays for novel biological targets or processes relevant to mental disorders.Projects for assay development should emphasize the design and validation of creative approaches to assess biological and disease processes that have the potential to be used as starting points for chemical probes or drug development.

Proposed primary screening assays must be relevant to neuroscience research aimed at discovering pathological processes of psychiatric disorders and developing safer and more effective treatments. The NIMH is interested in applications proposing the development of therapies aimed at novel molecular targets for the treatment of psychiatric disorders, such as treatment-resistant depression, bipolar disorder, schizophrenia, post-traumatic stress disorder (PTSD), panic disorder, and autism spectrum disorders.

Primary screening assays may be target-, pathway-, or phenotype-based. Some examples include:

  • Target-based biochemical or cellular assays that measure receptor-ligand binding, protein-protein interactions, activities of enzymes, ion channels, transporters, nuclear receptors, and other transcription factors, and other novel targets emerging from genetic, epigenomic, transcriptomic, proteomic, and metabolomic research in model systems and in human diseases
  • Cell- or organism-based assays that detect phenotypic changes linked to the biological or disease process of interest

Assays may utilize any preparation which enables high throughput screening (HTS) or moderate throughput screening (MTS), including cell-free systems, cultured cells, induced pluripotent stem cells (iPSCs), organoids, organotypic brain slices, or model organisms (e.g., zebrafish, Caenorhabditis elegans (C. elegans) and Drosophila melanogaster), which adequately recapitulate important aspects of neuronal or glial function.

Phenotypes of interest may include, but are not limited to, dendritic morphology; axonal outgrowth; neuronal activity and plasticity; synaptic maturation or synaptic function; neuronal and/or glial signaling pathways; receptor function, trafficking, and/or localization; protein synthesis, sorting, interactions, and turnover; cell fate specification; or chromatin remodeling.

Assay detection methods may include, but are not limited to:

  • Fluorescence, luminescence, absorbance
  • Fluorescence resonance energy transfer (FRET)
  • Time-resolved fluorescence resonance energy transfer (TR-FRET)
  • Fluorescence polarization
  • Flow cytometric measurements
  • Fluorescence imaging
  • Bioluminescence resonance energy transfer (BRET)
  • AlphaScreen, scintillation proximity assay (SPA)
  • Electrophysiology
  • Biophysical measures

In general, assays should adopt an adequate detection principle that results in the sensitive detection of even weak binders with expected low rates of false positives and false negatives. Complementary research, for example virtual screening, may also be conducted to improve the likelihood of success and cost-effectiveness.

Instructions for the design and testing of a primary assay may be found in Section IV (Application and Submission Information, PHS 398 Research Plan).

2. Primary Screen Implementation

Virtual Screening (VS)

This NOFO seeks to make use of large, publicly available databases of 3D protein structures, genomic, metabolomic, and proteomic data, and virtual small molecule libraries, combined with computational approaches to accelerate the discovery of novel and potential drug candidates based on specific molecular targets. Projects proposing the use of VS, either ligand-based screening or receptor-based screening, must collaborate with hit assay validation and medicinal chemistry experts for experimental testing of the proposed in silico hits.

VS techniques may involve computational approaches that include, but are not limited to:

  • Machine learning based QSAR (particularly deep learning methods)
  • Innovative protein-ligand docking algorithms (e.g., evolutionary search methods)
  • Similarity search methods
  • Pharmacophore mapping methods

Moderate throughput screening (MTS) and high throughput screening (HTS)

Applicants are encouraged to collaborate with an experienced MTS or HTS facility. The screening facility may provide advice such as identification and selection of commercial MTS/HTS assay reagents, and suitable MTH/HTS assay format and readout. In addition, the screening facility may be able to aid in adapting assays to an HTS format (e.g.,1536-well or 384-well microplate) and performing a pilot screen of a small library of compounds. Further, the applicants  are expected to seek advice from the screening laboratory about orthogonal assays to validate the screening hits.

Projects focusing on screen implementation are required to provide preliminary data demonstrating that a primary screen has been developed, fully characterized, and tested in a pilot format. See Section IV for further details on expected information prior to the Primary Screen Implementation stage.

Phenotypic and model organisms screening

In vivo whole organism assays (e.g., zebrafish, Caenorhabditis elegans (C. elegans) and Drosophila melanogaster) should only be proposed if they adequately recapitulate important aspects of neuronal or glial function and are needed to demonstrate the biological or physiological effects of validated hit compound(s).

Phenotypic screening should only be proposed if a target deconvolution is included in the application or there is a strong association between the mechanisms that drive the phenotypic assay, the preclinical disease model and the human disease.

3. Hit Validation

For purposes of this initiative, a “hit” is defined as a compound that has the desired activity in a compound screen and whose activity is confirmed upon retesting in orthogonal assays.

Hits from a primary screen may be systematically assessed using a cascade of follow-up assays to remove false positives efficiently and effectively. Primary HTS assays typically generate hundreds to thousands of hits, many of which are false positives or are chemically intractable. Hits from smaller scale primary screens are also likely to generate false positives or chemically intractable molecules that require additional screens. Post-primary screening assays may include, but are not limited to:

  • An assay that is essentially identical to the primary assay but with an orthogonal detection scheme (e.g., switching light detection mode or wavelength to avoid intrinsic compound interference);
  • A target-minus assay (e.g., coupling enzymes in the absence of the assay target enzyme, parental cell line without the assay target protein, etc.);
  • An assay that is different in biological context and process (e.g., protein functional assay vs. protein binding assay; RT-PCR or Western blot vs. reporter gene assay; cell-based assay vs. biochemical assay);
  • Cytotoxicity assay;
  • Target selectivity assay(s);
  • Specificity assays to distinguish biological activities of chemical entities among orthologous targets across organism species through kingdoms (e.g., yeast vs. mammalian cell targets; parasite vs. host targets);
  • Mode of action assays (e.g., allosteric vs. orthosteric; competitive vs. noncompetitive or uncompetitive); or 
  • Target identification assays.

Downstream assays may also include cellular and/or tissue models pertaining to the relevant physiology or pathophysiology, or to the mode and mechanism of action of the validated hits. In vivo whole organism assays (e.g., zebrafish, Caenorhabditis elegans (C. elegans) and Drosophila melanogaster) should only be proposed if they are needed to demonstrate the biological or physiological effects of validated hit compound(s).

In addition, applicants are expected to conduct advanced cheminformatics analysis and medicinal chemistry inspection to prioritize the hit set. It is expected that the applicants will test powder samples of hit compounds and commercially available analog compounds during the hit validation stage. Applicants must verify the chemical structures of hit compounds using a combination of analytical methods and, if possible, re-synthesis of select hits.

The NIMH encourages applications proposing novel, clinically relevant targets with the goal of transforming target discovery into the therapeutic treatment of psychiatric disorders such as depression, bipolar disorder, schizophrenia, anxiety, panic disorder, autism spectrum disorders, etc. (see From Discovery to Cure: Accelerating the Development of New and Personalized Interventions for Mental Illnesses). Proposed projects should be relevant to NIMH's mission of supporting basic science discoveries and translating these discoveries into new therapeutic interventions that will relieve the suffering of people with psychiatric disorders. Projects aimed at the discovery of in vivo chemical probes should consider applying to PAR-21-029. Projects aimed at the discovery of cell-based chemical probes should consider applying to PAR-21-028. Projects aimed at early stages of drug discovery and development should consider the Drug Discovery for Nervous System Disorders PAR-22-031 (R01) and PAR-22-032 (R21) or the National Cooperative Drug Discovery/Development Groups (NCDDG) for the Treatment of Mental Disorders, Drug or Alcohol Addiction PAR-22-144 (U19) and PAR-22-143 (U01)

Small businesses should consider applications through the Small Business Innovation Research Program.

Details on these and additional funding opportunity announcements and therapeutic discovery resources are listed on the NIH/NIMH Therapeutics Discovery Research webpage. Further information on NIMH research priorities can be found in the NIMH Strategic Plan, Strategic Research Priorities, and Interventions Workgroup Report. Applicants are strongly encouraged to discuss potential applications with NIMH staff listed in Section VII - Agency Contact(s), Scientific/Research Contacts prior to submission to determine the alignment of the planned studies with NIMH priorities and to assess whether this or other NIMH funding opportunities are most appropriate.

Research Strategy:  

Address the following topics as they pertain to the research project proposed:

Factor 1. Importance of the Research

Significance: Address whether the hit(s) will provide new insight into important disease targets and processes. Any existing modulators for the target should be mentioned, and a rationale for additional discovery and/or development of small molecules that address the target should be delineated.

Innovation: Innovative aspects of studying the proposed target or pathway and of the proposed assay(s) and screening scheme should be highlighted.

Factor 2. Rigor and Feasibility

Approach: Define the scope of the proposed research project via the three drug discovery research stages outlined in Section I. Include a flow diagram outlining all critical steps in sequential and/or parallel manners with appropriate benchmarks and timelines for the stage(s) of discovery research proposed. The application should include the following topics in the research plan:

1) Assay Development: An explanation of the scale of the proposed assay campaign (i.e., low-, moderate- or high-throughput), reproducibility of the primary screening assay, and reproducibility and robustness of the primary screening assay in a low-to-moderate throughput setting.

2) Primary Screen Implementation: A discussion of the following parameters: anticipated number of hits; feasibility of assessing hits (particularly in large numbers); test concentrations; cut-off concentration; reagent availability; equipment used in configuring the assay; a strategy to characterize initial active compounds, and a rationale for the size and selection of the library of compounds to be screened regardless of the scale of the screen.

3) Hit Validation: a rationale for the chosen hit validation scheme, considering the number of hits from the primary screen, anticipated false positives inherent in the primary assay format, and/or necessary assays to test the biology or physiology of the target, availability and suitability of secondary and counter-screen assays as appropriate for the scale of the screening campaign or plans to develop and characterize them, a definition of the specific criteria that a compound must meet to be considered a validated hit, a plan to conduct advanced cheminformatic analysis and medicinal chemistry inspection to prioritize the hit set, confirmation of hit compound structures by testing powder samples and commercially available analog compounds and resynthesis of selected hits.

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.

To advance the goal of advancing research through widespread data sharing among researchers, investigators funded under this Notice of Funding Opportunity (NOFO) are expected to share those data via the National Institute of Mental Health Data Archive (NDA; see NOT-MH-23-100). Established by the NIH, NDA is a secure informatics platform for scientific collaboration and data-sharing that enables the effective communication of detailed research data, tools, and supporting documentation. NDA links data across research projects through its Global Unique Identifier (GUID) and Data Dictionary technology. Investigators funded under this NOFO are expected to use these technologies to submit data to NDA.

To accomplish this objective, it will be important to formulate a) an enrollment strategy that will obtain the information necessary to generate a GUID for each participant, and b) a budget strategy that will cover the costs of data submission. The NDA website provides two tools to help investigators develop appropriate strategies: 1) the NDA Data Submission Cost Model which offers a customizable Excel worksheet that includes tasks and hours for the Program Director/Principal Investigator and Data Manager to budget for data sharing; and 2) plain language text to be considered in your informed consent available from the NDA's Data Contribution page. Investigators are expected to certify the quality of all data generated by grants funded under this NOFO prior to submission to NDA and review their data for accuracy after submission. Submission of descriptive/raw data is expected semi-annually (every January 15 and July 15); submission of all other data is expected at the time of publication, or prior to the end of the grant, whichever occurs first (see NDA Sharing Regimen for more information); Investigators are expected to share results, positive and negative, specific to the cohorts and outcome measures studied. For more guidance on submitting data to NDA, refer to the NDA Data Sharing Plan on the NDA website. NDA staff will work with investigators to help them submit data types not yet defined in the NDA Data Dictionary.

Appendix: Only limited Appendix materials are allowed. Follow all instructions for the Appendix as described in the How to Apply- Application Guide.

  • No publications or other material, with the exception of blank questionnaires or blank surveys, may be included in the Appendix.

5. Intergovernmental Review (E.O. 12372)

This initiative is not subject to intergovernmental review.

Use of Common Data Elements in NIH-funded Research

Many NIH ICs encourage the use of common data elements (CDEs) in basic, clinical, and applied research, patient registries, and other human subject research to facilitate broader and more effective use of data and advance research across studies. CDEs are data elements that have been identified and defined for use in multiple data sets across different studies. Use of CDEs can facilitate data sharing and standardization to improve data quality and enable data integration from multiple studies and sources, including electronic health records. NIH ICs have identified CDEs for many clinical domains (e.g., neurological disease), types of studies (e.g. genome-wide association studies (GWAS)), types of outcomes (e.g., patient-reported outcomes), and patient registries (e.g., the Global Rare Diseases Patient Registry and Data Repository). NIH has established a “Common Data Element (CDE) Resource Portal" (http://cde.nih.gov/) to assist investigators in identifying NIH-supported CDEs when developing protocols, case report forms, and other instruments for data collection. The Portal provides guidance about and access to NIH-supported CDE initiatives and other tools and resources for the appropriate use of CDEs and data standards in NIH-funded research. Investigators are encouraged to consult the Portal and describe in their applications any use they will make of NIH-supported CDEs in their projects.

NIMH expects investigators for this funding announcement to collect Common Data Elements (CDEs) for mental health human subjects research. Unless NIMH stipulates otherwise during the negotiation of the terms and conditions of a grant award, this Notice applies to all grant applications involving human research participants. The necessary funds for collecting and submitting these CDE data from all research participants to the NIMH Data Archive (NDA) should be included in the requested budget.

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:

Significance:

  • If the goal is to develop hit compounds as research tools, assess whether the application describe the potential of the hits to provide new insight into important disease targets and processes. If compounds exist for the proposed target, Evaluate the extent to which the rationale is convincing for additional discovery research.

Innovation:

  • Assess the novelty of the proposed assay design, compound screening scheme, and/or hit structures.
  • Evaluate the extent that the application describes the novelty of the biological target or pathway for the proposed disease being studied.
 

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 that the application describes the proposed timeline consistency with the scale and stages of discovery research proposed in the Aims.
  • Evaluate the extent that the application delineates the flow diagram outlining all critical steps in sequential and/or parallel manners with appropriate benchmarks and timelines for whichever stage(s) of discovery are proposed.

Specifically for each stage:

1) Assay Development:

  • Evaluate the extent that the scale is appropriate for the proposed assay campaign (i.e., low-, moderate- or high-throughput) for the selected target.
  • Assess whether the application addresses the reproducibility of the primary screening assay, the reproducibility and robustness of the primary assay in an automated, MHT or HTS approach, and the predictability and reproducibility of known compounds responses.

2) Primary screen implementation:

  • Assess whether the application addresses the discussion on the anticipated number of hits; feasibility of assessing hits (particularly in large numbers): test concentrations; cut-off concentration; reagent availability; equipment used in configuring the assay; and strategy to characterize initial active compounds.
  • Assess whether the application describes and sufficiently justifies the rationale for the size and selection of the library of compounds to be screened, regardless of the scale of the screen.

3) Hit validation:

  • Assess whether the application describes the rationale for the chosen hit validation scheme, considering the number of hits from the primary screen, anticipated false positives inherent in the primary assay format, and/or necessary assays to test the biology or physiology of the target.
  • Asses whether the application describes the availability and suitability of the secondary and counter-screen assays.
  • Asses whether the application describes the definition of the specific criteria that a compound must meet to be considered a validated hit.
  • Evaluate the extent that the application provides an adequate plan to conduct advanced cheminformatic analysis and medicinal chemistry inspection to prioritize the hit set.
  • Assess whether the application justifies the hit compound’s structure confirmation by testing powder samples and/or commercially available analog compounds and by re-synthesis of select hits.
  • Evaluate the extent that the application presents a description of the desired properties of validated hit series.
 

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.
