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).

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

• 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 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.
• 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. 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.

Does the project address an important problem or a critical barrier to progress in the field? Is the prior research that serves as the key support for the proposed project rigorous? 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 NOFO: How well is the target selection justified? How well does the application justify the 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, how well does the application describe the potential of the hits to provide new insight into important cancer targets and processes? If compounds exist for the proposed target, how convincing is the rationale provided for doing additional discovery research?

Investigator(s)

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 NOFO: How knowledgeable and experienced are the investigators about the biological target, pathway, and disease area? How adequate are the investigators’ knowledge and experience to perform the proposed discovery research stages? 

Innovation

Does the application challenge and seek to shift current research or clinical practice paradigms by utilizing novel theoretical concepts, approaches or methodologies, instrumentation, or interventions? Are the concepts, approaches or methodologies, instrumentation, or interventions novel to one field of research or novel in a broad sense? Is a refinement, improvement, or new application of theoretical concepts, approaches or methodologies, instrumentation, or interventions proposed?

Specific for this NOFO: How well does the application describe the novelty of the biological target or pathway for cancer? How well does the application assess the novelty of the proposed assay design and compound screening scheme?

Approach

Are the overall strategy, methodology, and analyses well-reasoned and appropriate to accomplish the specific aims of the project? Have the investigators included plans to address weaknesses in the rigor of prior research that serves as the key support for the proposed project? Have the investigators presented strategies to ensure a robust and unbiased approach, as appropriate for the work proposed? Are potential problems, alternative strategies, and benchmarks for success presented? If the project is in the early stages of development, will the strategy establish feasibility and will particularly risky aspects be managed? Have the investigators presented adequate plans to address relevant biological variables, such as sex, for studies in vertebrate animals or human subjects?

If the project involves human subjects and/or NIH-defined clinical research, are the plans to address 1) the protection of human subjects from research risks, and 2) inclusion (or exclusion) of individuals on the basis of sex/gender, race, and ethnicity, as well as the inclusion or exclusion of individuals of all ages (including children and older adults), justified in terms of the scientific goals and research strategy proposed?

Specific for this NOFO: How well does the critical path diagram outline critical steps in sequential and/or parallel manners with appropriate benchmarks and timelines for whichever stage(s) of discovery are proposed? How well does the proposed timeline reflect the scale and stage(s) of discovery research proposed in the Aims? How well do the preliminary data support the stage(s) of discovery research proposed in the Aims? Rarely, animal studies may be appropriate for the early stages of drug discovery in this NOFO. If animal studies are included, how well-justified and appropriate are they?

Stage-specific questions:

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

• How appropriate is the design and scale of the proposed assay campaign for the selected target?
• How sufficient are the reproducibility and robustness of the primary assay addressed?
• If a small-scale, pilot screen is proposed, is the scale of the screen and proposed library appropriate for the target?

2.         Primary screen implementation:

• How well do preliminary data, such as a small-scale pilot screen, support a proposed larger-scale screen?
• How well are the following aspects addressed in the application: anticipated number of hits and feasibility of assessing them; reagent availability; and strategy to characterize the initial active compounds?
• How well justified is the size and selection of the library?

3.         Hit validation:

• How well justified is the hit validation scheme, considering the number of hits from the primary screen, anticipated false positives inherent in the primary assay format, and/or assays to test the biology or physiology of the target?
• How well does the application address specific criteria that a compound must meet to be considered a validated hit, and how well rationalized are the criteria?
• How well justified is the plan to conduct advanced cheminformatic analysis, to do medicinal chemistry inspection to prioritize the hit set, and to disqualify a hit series? 

Environment

Will the scientific environment in which the work will be done contribute to the probability of success? Are the institutional support, equipment, and other physical resources available to the investigators adequate for the project proposed? Will the project benefit from unique features of the scientific environment, subject populations, or collaborative arrangements?

Section VI. Award Administration Information

1. Award Notices

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 recipient's business official.

Recipients must comply with any funding restrictions described in Section IV.6. 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 NOFO 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.

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

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, Recipients, and Activities, including of note, but not limited to:

• Federal-wide Standard Terms and Conditions for Research Grants
• Prohibition on Certain Telecommunications and Video Surveillance Services or Equipment
• Acknowledgment of Federal Funding

If a recipient is successful and receives a Notice of Award, 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.

Should the applicant organization successfully compete for an award, recipients of federal financial assistance (FFA) from HHS will be required to complete an HHS Assurance of Compliance form (HHS Assurance of Compliance form (HHS 690) in which the recipient agrees, as a condition of receiving the grant, to administer programs in compliance with federal civil rights laws that prohibit discrimination on the basis of race, color, national origin, age, sex and disability, and agreeing to comply with federal conscience laws, where applicable. This includes ensuring that entities take meaningful steps to provide meaningful access to persons with limited English proficiency; and ensuring effective communication with persons with disabilities. Where applicable, Title XI and Section 1557 prohibit discrimination on the basis of sexual orientation, and gender identity, The HHS Office for Civil Rights provides guidance on complying with civil rights laws enforced by HHS. See https://www.hhs.gov/civil-rights/for-providers/provider-obligations/index.html and https://www.hhs.gov/civil-rights/for-individuals/nondiscrimination/index.html.

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 NOFO.
