Section I. Notice of Funding Opportunity Description

Purpose & Background

Through this Notice of Funding Opportunity (NOFO), the National Cancer Institute (NCI) intends to support discovery research for the identification of small molecules that function to elucidate the biology of cancer as chemical probes or function as activators or inhibitors of cancer target(s) for therapy. The scientific rationale for target selection must be provided. Small molecule tools or therapeutics may target tumor cells themselves or immune cells regulating tumor growth. Stages of discovery research covered by this NOFO include: 1) development of the primary screen assay(s) and testing in an initial pilot screen. Assays may focus on specific biological targets or disease mechanisms relevant to cancer with the intent to screen for small molecule compounds to be used as probes for advancing knowledge about the known target(s), identifying new targets, or as pre-therapeutic leads; 2) screen implementation of high throughput target-focused approaches or moderate throughput phenotypic- and fragment-based approaches to identify initial screening hits; 3) hit validation, including implementation of secondary assays that are orthogonal to the primary assay, advanced cheminformatics analysis and initial medicinal chemistry inspection to prioritize the hit set, and follow-up assays to characterize mode and mechanism of action of the validated hits. It is anticipated that applications submitted in response to this NOFO will focus on one or two of the above stages, as each stage depends on success of the prior stage.

The small molecules for targets to be pursued must be relevant to understanding cancer biology, and/or for developing strategies for cancer prevention, diagnosis, treatment or clinical monitoring of treatment. In addition to targeting tumor cells themselves, applications targeting immune cells that regulate tumor development are appropriate for this NOFO. Small molecules that affect known immune checkpoint inhibitor pathways as well as small molecules that address emerging pathways involved in immune-mediated control of cancer are of interest. NCI also encourages projects focusing on small molecules that target pediatric fusion oncoproteins or that address novel targets in small cell lung cancer or pancreatic cancer. Applicants may find the NCI Developmental Therapeutics Program resources to be helpful. These include the NCI Program for Natural Product Discovery (NPNPD) Prefractionated Library which, as of March 2023, consisted of 500,000 natural product fractions that are available for screening.

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 is likely to be beneficial.

Although outside the scope of this NOFO, extensive chemical optimization of hit molecules to generate highly selective probes or drugs is a logical next step. Databases of small-molecule probes for the study of disease-related biological processes and mechanisms in academic environments may be found in the Academic Drug Discovery Consortium or the Chemical Probes Portal. 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 opens the door to validation of the target in appropriate cellular, tissue, or animal models prior to clinical testing. 

Research Scope

Projects for this NOFO may focus on one stage, or span several stages of discovery research:

1) development of the primary screen assay(s) and testing in an initial pilot screen

2) primary screen implementation

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. Development of primary screen assay(s) and testing in an initial pilot screen

Through this NOFO, NCI seeks to apply new knowledge and screening technologies to develop assays for novel cancer targets and pathways. Projects for assay development should emphasize the design and validation of creative approaches that have the 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 cancers are encouraged.

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 cancers;
• 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 the 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.

If achievable, pilot screening for target validation from a small compound library (e.g., LOPAC1280), should be proposed as a highly desirable validation step for translation of the assay to HTS. 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

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.

Virtual Screening (VS)

In addition to screens of chemical libraries, NCI, through 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;
• Similarity search methods; and
• Pharmacophore mapping methods.

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 aid in adapting assays to an HTS format (e.g., 1536-well or 384-well microplate). Further, the researchers might seek advice from the screening laboratory about orthogonal assays to validate the screening hits. Phenotypic screening should only be proposed if target deconvolution is included in the application or if there is a strong association between the mechanisms that drive the phenotypic assay, the preclinical disease model, and the human disease.

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 bi-monthly journal, and SLASDiscovery.

3. Hit validation

For the purposes of this NOFO, 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. 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);
• mode of action assays (e.g., allosteric vs. orthosteric; competitive vs. non-competitive or uncompetitive); and
• target identification assays. The assays farther downstream may also include cellular and tissue models pertaining to the 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.

Nonresponsive Applications

The following types of studies are beyond the scope of this NOFO. Applications proposing such studies will be considered non-responsive and will not be reviewed.

• Targets and associated screens and assays that are not relevant to cancer;
• Detailed structure-activity relationship (SAR) studies;
• In vitro or in vivo Absorption, Distribution, Metabolism, and Excretion (ADME) assays; and
• In vivo animal assays, unless justified as necessary for screening of hit molecule(s).

PHS 398 Research Plan

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

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

• Importance of the Research (Significance and Innovation): 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 cancer targets and processes. Preliminary data or published information demonstrating the significance of the target or pathway should be included. Any existing modulators for the target should be mentioned, and a rationale for doing additional development of small molecules that address the target should be delineated.

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

• Rigor and Feasibility (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. The application should include a flow diagram to outline all critical steps in sequential and/or parallel manners with appropriate benchmarks and timelines for whichever stage(s) of discovery are proposed.

Detailed guidelines for the three stages to be addressed in the Approach Section are as follows:

1) Assay development: To increase the overall likelihood of a successful assay development project, applicants should 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.
• Experiments to test predictability and reproducibility of responses to known compounds or other control conditions and 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 proposed 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 proposing to perform a screen of any scale should 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 should be maintained under strict storage conditions and meet a set of quality control restrictions on solubility, the 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 expected 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.
• Investigators may propose to confirm hit compounds by testing powder samples and commercially available analog compounds. If commercial analogs are available, investigators may propose preliminary SAR studies. Investigators should verify the structure of hits using a combination of analytical methods and, if possible, perform re-synthesis of select hits.

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 for whichever stage(s) of discovery are proposed. The flow diagram may include but is 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; and assay responsibilities of each party involved in the project.

A timeline is strongly encouraged, either as a separate figure or as part of the flow diagram. 

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:

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.

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. 

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.

As applicable for the project proposed, reviewers will consider each of the following items, but will not give scores for these items, and should not consider them in providing an overall impact score.

2. Review and Selection Process

Applications will be evaluated for scientific and technical merit by (an) appropriate Scientific Review Group(s) convened by Center for Scientific Review, in accordance with NIH peer review policy and procedures, using the stated review criteria. Assignment to a Scientific Review Group will be shown in the eRA Commons.

As part of the scientific peer review, all applications will receive a written critique.

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.

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 submitted in response to this NOFO. 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.

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 Section 2.5.1. Just-in-Time Procedures. This request is not a Notice of Award nor should it be construed to be an indicator of possible funding.

Prior to making an award, NIH reviews an applicant’s federal award history in SAM.gov to ensure sound business practices. An applicant can review and comment on any information in the Responsibility/Qualification records available in SAM.gov. NIH will consider any comments by the applicant in the Responsibility/Qualification records in SAM.gov to ascertain the applicant’s integrity, business ethics, and performance record of managing Federal awards per 2 CFR Part 200.206 “Federal awarding agency review of risk posed by applicants.” This provision will apply to all NIH grants and cooperative agreements except fellowships.

3. Anticipated Announcement and Award Dates

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 Section 2.4.4 Disposition of Applications.

Section VI. Award Administration Information

1. Award Notices

A Notice of Award (NoA) is the official authorizing document notifying the applicant that an award has been made and that funds may be requested from the designated HHS payment system or office. The NoA is signed by the Grants Management Officer and emailed to the recipient’s business official.

In accepting the award, the recipient agrees that any activities under the award are subject to all provisions currently in effect or implemented during the period of the award, other Department regulations and policies in effect at the time of the award, and applicable statutory provisions.

Recipients must comply with any funding restrictions described in Section IV.6. Funding Restrictions. Any pre-award costs incurred before receipt of the NoA are at the applicant's own risk.  For more information on the Notice of Award, please refer to the NIH Grants Policy Statement Section 5. The Notice of Award and NIH Grants & Funding website, see Award Process.

Institutional Review Board or Independent Ethics Committee Approval: Recipient institutions must ensure that protocols are reviewed by their IRB or IEC. To help ensure the safety of participants enrolled in NIH-funded studies, the recipient must provide NIH copies of documents related to all major changes in the status of ongoing protocols.

2. Administrative and National Policy Requirements

The following Federal wide and HHS-specific policy requirements apply to awards funded through NIH:

• The rules listed at 2 CFR Part 200, Uniform Administrative Requirements, Cost Principles, and Audit Requirements for Federal Awards.
• All NIH grant and cooperative agreement awards include the NIH Grants Policy Statement as part of the terms and conditions in the Notice of Award (NoA). The NoA includes the requirements of this NOFO. 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, Recipients, and Activities.
• If a recipient receives an award, the recipient must follow all applicable nondiscrimination laws. The recipient agrees to this when registering in SAM.gov. The recipient must also submit an Assurance of Compliance (HHS-690). To learn more, see the Laws and Regulations Enforced by the HHS Office for Civil Rights website.
  • HHS recognizes that NIH 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 NOFO.

All federal statutes and regulations relevant to federal financial assistance, including those highlighted in NIH Grants Policy Statement Section 4 Public Policy Requirements, Objectives and Other Appropriation Mandates.

Recipients are responsible for ensuring that their activities comply with all applicable federal regulations.  NIH may terminate awards under certain circumstances.  See 2 CFR Part 200.340 Termination and NIH Grants Policy Statement Section 8.5.2 Remedies for Noncompliance or Enforcement Actions: Suspension, Termination, and Withholding of Support. 

Not Applicable

Consistent with the 2023 NIH Policy for Data Management and Sharing, when data management and sharing is applicable to the award, recipients will be required to adhere to the Data Management and Sharing requirements as outlined in the NIH Grants Policy Statement. Upon the approval of a Data Management and Sharing Plan, it is required for recipients to implement the plan as described.

4. Reporting

When multiple years are involved, recipients will be required to submit the Research Performance Progress Report (RPPR) annually and financial statements as required in the NIH Grants Policy Statement Section 8.4.1 Reporting. To learn more about post-award monitoring and reporting, see the NIH Grants & Funding website, see Post-Award Monitoring and Reporting.

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 Section 8.6 Closeout. NIH NOFOs outline intended research goals and objectives. Post award, NIH will review and measure performance based on the details and outcomes that are shared within the RPPR, as described at 2 CFR Part 200.301.
