Part 2. Full Text of Announcement

Section I. Notice of Funding Opportunity Description

Purpose

This Notice of Funding Opportunity (NOFO) encourages the submission of research grant applications for the development of human positron emission tomography (PET) and single photon emission computed tomography (SPECT)tracers for molecular targets (e.g., receptors, intracellular messengers, disease-related proteins) that are implicated in mental disorders as tools to study disease pathophysiology and/or for assessing target engagement of potential therapeutic candidates. The objective of this NOFO is to stimulate research to advance the development and testing in humans of PET and SPECT probes for disorders of primary interest to the NIMH or NIA.

The use of radiotracers for imaging molecular events in preclinical and clinical studies is essential for understanding the circuitry that underlies normal brain function and the pathophysiology of brain disorders. The long-term goal of this NOFO is to facilitate the broad application of neuroimaging probes that are fit-for-purpose for their intended use in pathophysiological studies, drug discovery/development research, or biomarker development/qualification studies as quantifiable indicators of disease progression and treatment efficacy.

Background

Tremendous opportunities exist for the application of PET and SPECT imaging in human studies of the pathophysiology and treatment of brain disorders, but relatively few radioligands are currently available for functional imaging of target molecules implicated in normal brain function, and in brain and behavioral disorders. Increasing the availability of human PET and SPECT radiotracers will aid in: a) understanding the abnormal biological processes that underlie mood and cognitive disorders and other brain disorders; b) determining the interaction of a drug or drug candidate with a specified target; c) guiding initial dosing of new therapeutic agents; and d) identifying central biomarkers of the illness, with the potential to predict symptom onset, monitor the progression of the disease, and assess the efficacy of therapeutic compounds.

Research Scope

This NOFO is intended to stimulate the development of radioligands for molecular targets (e.g., receptors, cell adhesion molecules, intracellular messengers, and disease-related proteins) that are of broad interest to the brain sciences community. The widespread availability and use of these radioligands are expected to: 1) accelerate research on identifying and characterizing the neural circuits and pathways implicated in the pathophysiology of mental disorders, and 2) facilitate the identification of new therapeutic targets and the development of new compounds as potential therapeutic agents. Research partnerships among investigators in both academia and pharmaceutical and biotechnology industries are encouraged to more rapidly develop PET and SPECT radiotracers and apply neuroimaging in drug discovery, biomarker development/qualification, and pathophysiological studies.

The proposed development of a radioligands (agonist, antagonist, or allosteric modulator) for a molecular target or for a radioimaging probe to monitor changes in a cellular process should be well-justified and the resulting radiotracer fit for the intended purpose. There is limited interest, without compelling justification, in another tracer of the same class of targets listed in the CNS Radiotracer Table.

The preponderance of tracers for molecular targets developed and utilized to date fall into the pharmacologic class of orthosteric antagonists with the most notable exceptions being ligands for benzodiazepine and opiate receptors. Our understanding of the relationship between occupancy and downstream effects of agonists and allosteric modulators is still at an early stage such that ligands that would enable more in-depth exploration of such relationships would be of particular interest, especially for those neurotransmitter targets that represent opportunities for novel drug discovery.

In addition to PET tracers for potential therapeutic molecular targets, there is interest in tracers that bind to targets that can be used to monitor changes in cellular processes that are linked to brain plasticity or pathophysiology (e.g., neuroinflammation, neurogenesis, integrity of synapses, mitochondrial function). For instance, markers of microglial activation would fall into this class as would any binding site alteration that could be linked to neurodegenerative processes. Applications to develop these classes of tracers that are not amenable to validation with existing pharmacologic tool compounds should include a description of a feasible validation path (e.g., differences in binding as a function of the degree of brain pathology).

Prioritization of molecular targets for ligand development is an ongoing exercise and interested parties are encouraged to contact the appropriate NIH Program Officer listed in the NIH Scientific/Research Contacts to discuss the perceived level of need for a particular human PET tracer.

Note: A feasibility assessment (e.g., density and affinity of the tracer target in brain region(s) of interest in post-mortem human brain) must be conducted, or reference to such information in the published literature, before submission of a tracer discovery project.

Proposed studies may include one or more of the following:

  • Lead compound identification/development and syntheses of chemicals with suitable binding affinity and selectivity, biodistribution, pharmacokinetics, and physiochemical properties allowing radiochemical synthesis.
  • Pre-clinical studies, including initial pharmacology and toxicology to screen out compounds that are unlikely to be promising candidates for PET or SPECT imaging; radiolabeling procedures; in vitro and ex vivo autoradiography; in vivo imaging including micro-PET; and studies of pharmacological specificity, biodistribution, and pharmacokinetics.
  • Establishment of appropriate compartmental models and/or graphical plots to quantify kinetic profiles, including binding potential, volume of distribution and test-re-test consistency for target engagement studies.

The development and strengthening of partnerships between scientists from academia and the pharmaceutical industry are highly desirable outcomes of this NOFO and are strongly encouraged. Pharmaceutical scientists are encouraged to actively participate as PDs/PIs or key personnel/collaborators.

Researchers uncertain as to whether their intended project meets the overall focus of this NOFO are encouraged to contact the appropriate NIH Program Officer listed in the NIH Scientific/Research Contacts to discuss the perceived level of need for a particular PET or SPECT tracer.

Specific Areas of Interest

National Institute of Mental Health

Areas of interest include, but are not limited to:

NIMH supports neuroscience research to discover the causes of mental illness and to develop more effective and safer treatments. Specifically, the NIMH is interested in the discovery of innovative treatment development targets for mental disorders and for advancing our understanding of the pathological processes contributing to disorders.

NIMH is particularly interested in developing probes that can be used to assess the adequacy of target engagement in clinical trials that employ an experimental medicine approach http://www.nimh.nih.gov/funding/opportunities-announcements/clinical-trials-foas/index.shtml

Further information on NIMH research priorities can be found in the NIMH Strategic Plan, Strategic Research Priorities, and Interventions Workgroup Report.

The NIMH has published updated policies and guidance for investigators regarding human research protection and clinical research data and safety monitoring (NOT-MH-19-027). The application’s PHS Human Subjects and Clinical Trials Information, including the Data and Safety Monitoring Plan, should reflect the policies and guidance in this notice. Plans for the protection of research participants and data and safety monitoring will be reviewed by the NIMH for consistency with NIMH and NIH policies and federal regulations.

National Institute on Aging

Under this PAR, NIA invites applications that propose to develop PET Radiotracers suitable for use in AD and ADRD research in human subjects as biomarkers or in drug development. The research should focus on new and/or emerging targets associated with biological processes and/or molecular pathways relevant in the etiology and pathophysiology of neurodegeneration. Approaches may include both novel tracers, as well as, the repurposing/pharmacodynamic and/or emission improvement of existing tracers for use in AD/ADRD research in humans. Leveraging multi-omic datasets, such as Agora's targets database or other publicly accessible resources, for the prioritization of candidate targets for ligand development is encouraged, but not required. For further information refer to: NOT-AG-22-032.

Institute Interests Areas of Lower Priority

Projects proposing to develop probes where PET or SPECT ligands already exist may be of lower programmatic interest to participating NIH Institutes, unless applicants provide a compelling case that there are significant advantages to their approach.

Research Strategy: Applicants must include the following information as part of the Research Strategy:

1. Provide a justification for why a radiotracer is needed for the target. Include the intended uses of the tracer and examples of questions that the tracer will enable to be addressed. The involvement of a biological advisor or collaborator, who would use the radiotracer to address clinical questions, or feedback from the field, is encouraged in the selection of the tracer target and in the design of the validation studies in animal models or human biological specimen. The emphasis should be on advancing novel tracers that are not redundant with currently available PET ligands. There is limited interest, without compelling justification, in another tracer of the same class of targets listed in the CNS Radiotracer Table.

2. Address the feasibility of developing a radiotracer for the target: data regarding the density and affinity of the tracer target in brain region(s) of interest in post-mortem human brain) must be included, or reference to such information in the published literature provided, before submission of a tracer discovery project.

3. State a plan and timeline for achieving the desired properties for the radiotracer (see considerations below).

Critical considerations for lead compound identification and development:

1. Feasibility based on the density and affinity of the tracer target in brain region(s) of interest in post-mortem human brain.

2. Affinity, lipophilicity, and target selectivity

a. Bmax/Kd > 5 in human subjects

b. Lipophilicity: logD (ideally ~ 2)

c. Target selectivity in brain region of interest; appropriate for proposed context of radiotracer use

3. Delivery: adequate penetration of blood-brain barrier with standardized uptake values (SUV) > 2 in the brain regions of interest, without influence by ABC efflux transporters and lack of substrate for ABCB1 (P-glycoprotein) or ABCG2 (BCRP)

4. Amenability to labeling with 11C or 18F and metabolic stability of the label (e.g., 18F label is in a metabolically stable position)

5. Amenability to production: radiochemical yield (%); practical yield (MBq); specific activity

6. Specific binding: sufficient binding potential (BP) or volume of distribution (BP > 2) to assess target occupancy by drugs or to characterize CNS pathophysiology

Considerations for in vivo assessment of a PET radiotracer candidate:

1. Lack of radiometabolites: within brain, or of [18F] fluoride ion in skull

2. Amenability to accurate quantification: e.g., stable total distribution volume (VT) within scan session

3. Time-activity curves for brain and plasma

4. Robust test-retest reliability: < 10% by variation

5. Compartmental modeling with arterial input function

The letter(s) of support must detail the involvement of a biological advisor or collaborator, who would use the radiotracer to address clinical questions, or feedback from the field.

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. 

A cost estimator (https://nda.nih.gov/ndarpublicweb/Documents/NDA_Data_Submission_Costs.xlsx) is available to facilitate the calculation of these costs. NIMH may seek further information regarding CDEs prior to award. Additional information about CDEs can be found at the NIMH webpage on Data Sharing for Applicants and Awardees.

6. Funding Restrictions

All NIH awards are subject to the terms and conditions, cost principles, and other considerations described in the NIH Grants Policy Statement.

Pre-award costs are allowable only as described in the NIH Grants Policy Statement Section 7.9.1 Selected Items of Cost.

  • Evaluate whether the proposed work applies novel concepts, methods or technologies or uses existing concepts, methods, technologies in novel ways, to enhance the overall impact of the project.

Specific to this NOFO: 

  • Evaluate the justification for the development of a radiotracer for the target or cellular process, for the proposed tracer's intended use(s), and types of questions that it would enable to be addressed.
 

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 how well the application describes the feasibility that the target can be detected in the brain region(s) of interest with a radiotracer. 
  • Evaluate how well the application describes the desired properties for the radiotracer for the proposed target. 
  • Evaluate how well the application describes the plan and timeline for achieving the desired properties for the radiotracer.
 

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.

Specific to this NOFO:

  • Evaluate how well the application describes the involvement of a biological collaborator or advisor, who would use the radiotracer or feedback from the field in the selection of the tracer target?
