Through this FOA, NIH wishes to stimulate research in 1) discovery and development of novel, small molecules for their potential use in studying disease treatment relevant to the missions of the participating NIH Institutes, and 2) generation of new insight into the biology of relevant diseases and processes that have yet to be validated as important drug targets.

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 FOA:

• 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, 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.
• A final area for improvement is the optimization of hits to yield high quality probes. Technological innovations in high throughput screening, chemical synthesis, and cheminformatics have allowed rapid discovery of novel, small-molecule probes for the study of disease related biological processes and mechanisms in academic environments (see Academic Screening Facilities Directory; Academic Drug Discovery Consortium). The Chemical Probes Portal, established in July 2015, provides a list of credentialed probes. It is noted that probes may be the predecessors of drugs, but drugs with known off-target effects are seldom useful as probes of specific biological activities. Importantly, identification of chemical probe(s) for a given target provides an unprecedented opportunity for investigators to translate knowledge about diseases into tangible tools for translational research and opens the door to validation of the target prior to clinical testing.

Projects for this FOA may span up to three stages of discovery research:

1) assay development;

2) primary screen implementation; and

3) hit validation.

For applications requesting support for more than one stage, demonstration of feasibility is needed, including strong justification and supporting preliminary data for the stages proposed. 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 FOA seeks to apply new knowledge and screening technologies to develop assays for novel targets and pathways. Projects for assay development should emphasize the design and validation of creative approaches to assay biological and disease processes that have potential to be used for chemical probe or drug discovery. Assays focusing on areas and approaches that have been extensively studied should be avoided unless a strong rationale is provided for additional studies in the projected area. Targets associated with rare and neglected diseases are encouraged.

Proposed primary screening assays should be relevant to the scope of the research within at least one of the participating NIH ICs focusing on specific diseases or on relevant basic physiology, cell biology, or developmental processes that provide insight into a disease.

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

• target-based biochemical or cellular assays that measure activities of enzymes, receptor-ligand binding, protein-protein interactions, ion channels, transporters, nuclear receptors and other transcription factors, and other new targets emerging from genetic and proteomic research in model systems and in human diseases;
• cell- or organism-based assays that detect phenotypic changes that may involve unidentified molecular targets; and
• non-traditional targets of interest such as nucleic acids, protein folding, polymorphic gene products, post-transcriptional editing or gene splicing factors, and protein or RNA stabilizers.

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);
• electrophysiological assays, and;
• biophysical assays.

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

Additional considerations 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

Applicants are encouraged to collaborate with an experienced screening facility, particularly if high throughput screening (HTS) is planned. The screening facility may provide advice such as identification and selection of commercial HTS assay reagents, and suitable HTS assay format and readout. In addition, the screening facility may be able to provide assistance 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 researchers might seek advice from the screening laboratory about orthogonal assays to validate the screening hits, and about chemical improvement of the initial hits via a structure-activity relationship (SAR) study following hit validation.

Projects focusing on screen implementation are encouraged 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.

Other technical resources about assay development and screening include the online comprehensive guidebook (Assay Guidance Manual), assay protocols deposited on the PubChem BioAssay data base, ASSAY and Drug Development Technologies, a peer-reviewed bimonthly journal, and the Journal of Biomolecular Screening.

3. Hit validation

Hits from a primary screen may be systematically assessed using a cascade of follow-up assays to efficiently and effectively remove false positives. 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:

• 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 and Western assay 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); and
• target identification assays. The assays farther downstream may also include cellular and tissue models pertaining to the relevant physiology or pathophysiology.
• assays farther downstream may include cellular and tissue models pertaining to relevant physiology or pathophysiology, or to mode and mechanism of action of the validated hits. In vivo assays (e.g. whole animal models) should only be proposed if they are needed to demonstrate the biological or physiological effects of lead compound(s).

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

Screening campaigns may yield validated hits that can be further optimized via medicinal chemistry. Extensive medicinal chemistry optimization is not appropriate for this FOA. Investigators of a successful screening project are encouraged to consider further funding opportunities to support medicinal chemistry optimization of the validated hits (e.g. see Institute Interests below).

Institute Interests

NCI: Assays and screens pertinent to the mission of NCI should be justified in the application as relevant to cancer.

Research Strategy: Applicants should address the following topics as they pertain to the research project proposed:

• Significance: Applicants should address why the chosen target or pathway is significant for the proposed chemical probe/drug discovery project, and whether the probe will provide new insight into important disease targets and processes. Preliminary data or published information demonstrating significance of the target or pathway should be included. Any existing modulators for the target should be mentioned, and a rationale for doing additional screening for small molecules that address the target should be delineated. Applications that propose interaction with existing research opportunities funded by one of the sponsoring NIH Institutes are encouraged.
• Innovation: Innovative aspects of studying the proposed target or pathway, and of the proposed assay(s) and screening scheme should be highlighted.
• Approach: Applicants are highly encouraged to define the scope of the proposed research project via the drug discovery stages outlined in Section I and to propose a timeline and budget in keeping with the scope. Preliminary data are required to substantiate the proposed scope. For instance, if a project for HTS through hit validation is proposed (Stages 2 and 3), preliminary data should address the topics mentioned below under Assay Development, as appropriate to the project.

Detailed guidelines for the three stages are as follows:

1) Assay development: To increase the overall likelihood of a successful assay development project, applicants are encouraged to include the following topics in the research plan:

• Explanation of the scale of the proposed assay campaign (i.e. low-, moderate- or high-throughput), in keeping with the selected target. If available, include preliminary data supporting the choice of the primary screening assay for the specific target.
• Reproducibility of the primary screening assay in a low-to-moderate throughput setting. If the goal is to perform a high-throughput screen, the research plan should include experiments to test whether the primary assay is sufficiently reproducible and robust for adaptation to an automated, high-throughput screening approach using a diverse and significant number of compounds (e.g. a collection of FDA-approved drugs or other bioactive molecules). Possible considerations when designing and characterizing a primary screening assay include effects of time, temperature and protein concentration; tolerance to the effect of DMSO at 0.1-1%; and reproducibility between plates and day-to-day experiments. Additional considerations for HTS are simplicity of the readout and ability for the primary assay to be miniaturized into formats such as 96-, 384-, or 1536-well automated screens.
• Predictability and reproducibility of responses to known compounds or other control conditions and of a clear threshold between positive and negative responses. In general, an acceptable lower limit of Z factor is 0.5 for a robust single-concentration HTS that corresponds to a combination of Signal-to-Basal Ratio (S/B) of 4 with a Coefficient of Variation (CV) of 10%. Assay robustness will improve if multiple compound test concentrations or kinetic recordings are used in HTS.
• Availability of reagents necessary to perform the screen, such as enzyme indicators, chemicals necessary for reagent readout, and the capacity to generate sufficient reaction substrates (DNA, RNA, protein, or enzyme substrates).
• If achievable, pilot screening for target validation from a small compound library (e.g. LOPAC1280), or other bioactive molecules should be performed as a highly desirable validation step for translation of the assay to HTS. Alternatively, dose-ranging studies for a limited set of agents having known interaction with the proposed target should be proposed. The intent of this characterization is to demonstrate the ability of the assay to pharmacologically distinguish structurally diverse compounds.

2) Primary Screen implementation: Applications to perform a screen of any scale are encouraged to include preliminary data to address the topics described above in the Assay Development section. In addition, the topics mentioned under Screen Implementation in Section I should be considered when writing the Approach section. Specifically, applications are expected to include:

• Preliminary data on the primary screening assay performance as tested in a small-scale pilot screen, including a scatter plot with a Z factor above 0.5 (see Assay Development section above).
• Discussion of the following parameters: anticipated number of hits; feasibility of assessing hits (particularly large numbers); test concentrations; cut-off concentration; reagent availability; equipment used in configuring the assay; strategy to characterize initial active compounds.
• A rationale for the size and selection of the library of compounds to be screened regardless of the scale of the screen. In certain cases, it may be advantageous to utilize focused libraries of compounds with specific consideration of assay targets, known bioactivities, privileged scaffolds, representative diversity sets, drug repurposing, and/or the ease of follow-up synthetic chemistry for SAR expansion. The compounds are expected to be maintained under strict storage conditions and meet a set of quality control restrictions on solubility, number of reactive groups, and compound size.

3) Hit validation: The Approach section of the grant application is expected to include the following:

• A clear 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. Preliminary data demonstrating feasibility of hit validation assays will strengthen the application.
• Definition of the specific criteria that a compound must meet to be considered a probe or pre-therapeutic lead for the project.
• A plan to conduct advanced cheminformatics analysis and medicinal chemistry inspection to prioritize the hit set.

Critical path: The application should include a flow diagram to outline all critical steps in sequential and/or parallel manners with appropriate benchmarks and timelines, including but not limited to the primary assay to be implemented or previously implemented, alternative assay or approach (e.g., computational docking) to ensure success of the screening, hit selection criteria, cheminformatic analysis, chemical tractability assessment, all follow-up assays to validate screening hits, study of structure-activity relationships, and assay responsibilities of each party involved in the project.

Future plans: The application should briefly describe existing and potential follow-up assays to develop chemical probes in the future.

Resource Sharing Plan: Individuals are required to comply with the instructions for the Resource Sharing Plans as provided in the SF424 (R&R) Application Guide, with the following modification:

• All applications, regardless of the amount of direct costs requested for any one year, should address a Data Sharing Plan.
• For this FOA, the following data generated or developed under this FOA are expected to be released to PubChem: (1) primary assay data from high throughput screening (HTS), (2) data generated in all post-HTS follow-up assays, (3) protocols for assays implemented, and (4) the chemical structure of compounds tested.
• Applications should include a statement of willingness to deposit the aforementioned data to PubChem within the Data Sharing section of the application, consistent with achieving the goals of this program.

Important Update: See NOT-OD-18-228 for updated review language for due dates on or after January 25, 2019.

Only the review criteria described below will be considered in the review process. As part of the NIH mission, all applications submitted to the NIH in support of biomedical and behavioral research are evaluated for scientific and technical merit through the NIH peer review system.

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 review criteria and additional review criteria (as applicable for the project proposed).

Reviewers will consider each of the review criteria below in the determination of scientific merit, and give a separate score for each. An application does not need to be strong in all categories to be judged likely to have major scientific impact. For example, a project that by its nature is not innovative may be essential to advance a field.

Does the project address an important problem or a critical barrier to progress in the field? Is there a strong scientific premise for the project? If the aims of the project are achieved, how will scientific knowledge, technical capability, and/or clinical practice be improved? How will successful completion of the aims change the concepts, methods, technologies, treatments, services, or preventative interventions that drive this field?

Specific for this FOA: Are there important and well-defined goals for the use of chemical probes, either as research tools or for therapeutics development? If the goal is to develop chemical probes as research tools, will the probes provide new insight into important disease targets and processes? If compounds exist for the proposed target, is a rationale provided for doing additional discovery research?

Are the PD(s)/PI(s), collaborators, and other researchers well suited to the project? If Early Stage Investigators or those in the early stages of independent careers, do they have appropriate experience and training? If established, have they demonstrated an ongoing record of accomplishments that have advanced their field(s)? If the project is collaborative or multi-PD/PI, do the investigators have complementary and integrated expertise; are their leadership approach, governance and organizational structure appropriate for the project?

Specific for this FOA: Are the investigators knowledgeable and experienced about the biological target, pathway, and disease area? Are the investigators knowledgeable and experienced about the process of screening compound libraries, at the scale and format proposed (e.g. moderate, high-throughput, high content)? Are the investigators knowledgeable and experienced to conduct the proposed follow-up assays to validate screening hits?

Assignment to a Scientific Review Group will be shown in the eRA Commons.

As part of the scientific peer review, all applications:

• May undergo a selection process in which only those applications deemed to have the highest scientific and technical merit (generally the top half of applications under review) will be discussed and assigned an overall impact score.
• Will receive a written critique.

Applications will be assigned on the basis of established PHS referral guidelines to the appropriate NIH Institute or Center. Applications will compete for available funds with all other recommended applications. Following initial peer review, recommended applications will receive a second level of review by the appropriate national Advisory Council or Board. The following will be considered in making funding decisions:

• Scientific and technical merit of the proposed project as determined by scientific peer review.
• Availability of funds.
• Relevance of the proposed project to program priorities.

After the peer review of the application is completed, the PD/PI will be able to access his or her Summary Statement (written critique) via the eRA Commons. Refer to Part 1 for dates for peer review, advisory council review, and earliest start date.

Information regarding the disposition of applications is available in the NIH Grants Policy Statement.

If the application is under consideration for funding, NIH will request "just-in-time" information from the applicant as described in the NIH Grants Policy Statement.

A formal notification in the form of a Notice of Award (NoA) will be provided to the applicant organization for successful applications. The NoA signed by the grants management officer is the authorizing document and will be sent via email to the grantee’s business official.

Awardees must comply with any funding restrictions described in Section IV.5. Funding Restrictions. Selection of an application for award is not an authorization to begin performance. Any costs incurred before receipt of the NoA are at the recipient's risk. These costs may be reimbursed only to the extent considered allowable pre-award costs.

Any application awarded in response to this FOA will be subject to terms and conditions found on the Award Conditions and Information for NIH Grants website. This includes any recent legislation and policy applicable to awards that is highlighted on this website.

All NIH grant and cooperative agreement awards include the NIH Grants Policy Statement as part of the NoA. For these terms of award, see the NIH Grants Policy Statement Part II: Terms and Conditions of NIH Grant Awards, Subpart A: General and Part II: Terms and Conditions of NIH Grant Awards, Subpart B: Terms and Conditions for Specific Types of Grants, Grantees, and Activities. More information is provided at Award Conditions and Information for NIH Grants.

Recipients of federal financial assistance (FFA) from HHS must administer their programs in compliance with federal civil rights law. This means that recipients of HHS funds must ensure equal access to their programs without regard to a person’s race, color, national origin, disability, age and, in some circumstances, sex and religion. This includes ensuring your programs are accessible to persons with limited English proficiency. HHS recognizes that research projects are often limited in scope for many reasons that are nondiscriminatory, such as the principal investigator’s scientific interest, funding limitations, recruitment requirements, and other considerations. Thus, criteria in research protocols that target or exclude certain populations are warranted where nondiscriminatory justifications establish that such criteria are appropriate with respect to the health or safety of the subjects, the scientific study design, or the purpose of the research.

For additional guidance regarding how the provisions apply to NIH grant programs, please contact the Scientific/Research Contact that is identified in Section VII under Agency Contacts of this FOA. HHS provides general guidance to recipients of FFA on meeting their legal obligation to take reasonable steps to provide meaningful access to their programs by persons with limited English proficiency. Please see https://www.hhs.gov/civil-rights/for-individuals/special-topics/limited-english-proficiency/index.html. The HHS Office for Civil Rights also provides guidance on complying with civil rights laws enforced by HHS. Please see http://www.hhs.gov/ocr/civilrights/understanding/section1557/index.html; and https://www.hhs.gov/civil-rights/for-providers/laws-regulations-guidance/index.html. Recipients of FFA also have specific legal obligations for serving qualified individuals with disabilities. Please see http://www.hhs.gov/ocr/civilrights/understanding/disability/index.html. Please contact the HHS Office for Civil Rights for more information about obligations and prohibitions under federal civil rights laws at https://www.hhs.gov/ocr/about-us/contact-us/index.html or call 1-800-368-1019 or TDD 1-800-537-7697. Also note it is an HHS Departmental goal to ensure access to quality, culturally competent care, including long-term services and supports, for vulnerable populations. For further guidance on providing culturally and linguistically appropriate services, recipients should review the National Standards for Culturally and Linguistically Appropriate Services in Health and Health Care at http://minorityhealth.hhs.gov/omh/browse.aspx?lvl=2&lvlid=53.

In accordance with the statutory provisions contained in Section 872 of the Duncan Hunter National Defense Authorization Act of Fiscal Year 2009 (Public Law 110-417), NIH awards will be subject to the Federal Awardee Performance and Integrity Information System (FAPIIS) requirements. FAPIIS requires Federal award making officials to review and consider information about an applicant in the designated integrity and performance system (currently FAPIIS) prior to making an award. An applicant, at its option, may review information in the designated integrity and performance systems accessible through FAPIIS and comment on any information about itself that a Federal agency previously entered and is currently in FAPIIS. The Federal awarding agency will consider any comments by the applicant, in addition to other information in FAPIIS, in making a judgement about the applicant’s integrity, business ethics, and record of performance under Federal awards when completing the review of risk posed by applicants as described in 45 CFR Part 75.205 Federal awarding agency review of risk posed by applicants. This provision will apply to all NIH grants and cooperative agreements except fellowships.

Cooperative Agreement Terms and Conditions of Award

Not Applicable

When multiple years are involved, awardees will be required to submit the Research Performance Progress Report (RPPR) annually and financial statements as required in the NIH Grants Policy Statement.

A final RPPR, invention statement, and the expenditure data portion of the Federal Financial Report are required for closeout of an award, as described in the NIH Grants Policy Statement.

The Federal Funding Accountability and Transparency Act of 2006 (Transparency Act), includes a requirement for awardees of Federal grants to report information about first-tier subawards and executive compensation under Federal assistance awards issued in FY2011 or later. All awardees of applicable NIH grants and cooperative agreements are required to report to the Federal Subaward Reporting System (FSRS) available at www.fsrs.gov on all subawards over $25,000. See the NIH Grants Policy Statement for additional information on this reporting requirement.

In accordance with the regulatory requirements provided at 45 CFR 75.113 and Appendix XII to 45 CFR Part 75, recipients that have currently active Federal grants, cooperative agreements, and procurement contracts from all Federal awarding agencies with a cumulative total value greater than $10,000,000 for any period of time during the period of performance of a Federal award, must report and maintain the currency of information reported in the System for Award Management (SAM) about civil, criminal, and administrative proceedings in connection with the award or performance of a Federal award that reached final disposition within the most recent five-year period. The recipient must also make semiannual disclosures regarding such proceedings. Proceedings information will be made publicly available in the designated integrity and performance system (currently FAPIIS). This is a statutory requirement under section 872 of Public Law 110-417, as amended (41 U.S.C. 2313). As required by section 3010 of Public Law 111-212, all information posted in the designated integrity and performance system on or after April 15, 2011, except past performance reviews required for Federal procurement contracts, will be publicly available. Full reporting requirements and procedures are found in Appendix XII to 45 CFR Part 75 Award Term and Conditions for Recipient Integrity and Performance Matters.
