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.

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 human 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 advancement and testing in humans of radioligands for molecular targets (e.g., receptors, cell adhesion molecules, intracellular messengers, and disease-related proteins) that are of broad interest to the scientific 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 in human studies and apply neuroimaging in drug discovery, biomarker development/qualification, and pathophysiological studies.

The proposed development of a radioligand in humans (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, or for targets in which a radioligand development effort is underway in the pharmaceutical industry.

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 primate imaging including micro-PET; and studies of pharmacological specificity, biodistribution, and pharmacokinetics.

Proposed studies must include some combination of the following:

• Determination of toxicology (FDA approved) for submission of an exploratory Investigational New Drug (IND) application or IND application.
• Exploratory IND or IND application development and submission to the FDA prior to pilot human studies.
• Pilot human imaging studies with normal controls, pharmacological challenges with analyses of radiometabolites under the auspices of IRB approval (e.g., exploratory IND or IND development and submission)
• Pilot studies of the PET or SPECT radiotracer in patient/disease populations to assess its utility for research in pathophysiology, drug discovery, or biomarker development.

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.

Applicants interested in only the animal preclinical phase (not involving human subjects) of development of novel PET or SPECT radioligands should apply to the companion R01 TEMP-20714.

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.

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. 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, or for targets in which a radioligand development effort is underway in the pharmaceutical industry.S .

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.

Applicants are required to follow the instructions for post-submission materials, as described in the policy

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.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 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.

The NIMH has published policies and guidance for investigators regarding human research protection, data and safety monitoring, Independent Safety Monitors and Data and Safety Monitoring Boards, reportable events, and participant recruitment monitoring (NOT-MH-19-027). The application’s PHS Human Subjects and Clinical Trials Information should reflect the manner in which these policies will be implemented for each study record. These plans will be reviewed by the NIMH for consistency with NIMH and NIH policies and federal regulations. The NIMH will expect clinical trials to be conducted in accordance with these policies including, but not limited to: timely registration to ClinicalTrials.gov, submission of review determinations from the clinical trial’s data and safety monitoring entity (at least annually), timely submission of reportable events as prescribed, and establishment of recruitment milestones and progress reporting.

Individual awards are based on the application submitted to, and as approved by, the NIH and are subject to the IC-specific terms and conditions identified in the NoA.

ClinicalTrials.gov: If an award provides for one or more clinical trials. By law (Title VIII, Section 801 of Public Law 110-85), the "responsible party" must register and submit results information for certain “applicable clinical trials” on the ClinicalTrials.gov Protocol Registration and Results System Information Website (https://register.clinicaltrials.gov). NIH expects registration and results reporting of all trials whether required under the law or not. For more information, see https://grants.nih.gov/policy/clinical-trials/reporting/index.htm

Institutional Review Board or Independent Ethics Committee Approval: Recipient institutions must ensure that all 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.

Data and Safety Monitoring Requirements: The NIH policy for data and safety monitoring requires oversight and monitoring of all NIH-conducted or -supported human biomedical and behavioral intervention studies (clinical trials) to ensure the safety of participants and the validity and integrity of the data. Further information concerning these requirements is found at http://grants.nih.gov/grants/policy/hs/data_safety.htm and in the application instructions (SF424 (R&R) and PHS 398).

Investigational New Drug or Investigational Device Exemption Requirements: Consistent with federal regulations, clinical research projects involving the use of investigational therapeutics, vaccines, or other medical interventions (including licensed products and devices for a purpose other than that for which they were licensed) in humans under a research protocol must be performed under a Food and Drug Administration (FDA) investigational new drug (IND) or investigational device exemption (IDE).

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 Research Terms and Conditions
• 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 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.
