NIH Exploratory/Developmental Research Grant

Helps NIH Exploratory and Developmental Research Grant for novel ideas and preliminary studies.

National Institutes of HealthUnited StatesGrant

The NIH Exploratory/Developmental Research Grant (R21) is the exploratory counterpart to the R01, built for novel ideas, high-risk directions, and early studies that do not yet have R01-level preliminary data. Two parent NOFOs are active, with clinical-trial required and not-allowed variants open through January 8, 2028.

It is a grant mechanism with three cycles per year and standard new-applicatโ€ฆ

Each grant below is a distinct funding opportunity with its own eligibility, scope, and deliverables.

Exploratory Grants in Cancer Control
Open

Funds the early, conceptual stage of a new idea in cancer control โ€” behaviour, screening, causes, or a technique nobody has tried yet.

- pool
NIH Exploratory/Developmental Research Project Grant
Open

Funds an early-stage, high-risk project that includes a clinical trial โ€” and at some institutes only a mechanistic one counts.

- pool
Cellular and Molecular Biology of Complex Brain Disorders (R21)
Between cycles

Funds short, exploratory work on what genetic risk factors for brain disorders actually do inside cells and circuits.

- pool
Schizophrenia and related disorders during mid- to late-life (R21)
Between cycles

Funds short, exploratory work on how schizophrenia emerges and changes after 35 โ€” the age group nearly all the research has skipped.

- pool
Mechanisms that Impact Cancer Risk after Bariatric Surgery (R21)
Open

Funds proof-of-concept work on how bariatric surgery changes cancer risk โ€” and refuses applications that already have unpublished preliminary data.

- pool
Novel Mechanism Research on Neuropsychiatric Symptoms (NPS) in Alzheimer's Dementia (R21)
Between cycles

Funds short, exploratory work on what causes agitation, apathy and psychosis in dementia โ€” and what could be targeted to stop it.

- pool
Social disconnection and Suicide Risk in Late Life (R21)
Between cycles

Funds short, exploratory work on how isolation and loneliness raise suicide risk in later life, and what prevents it.

- pool
Pilot Studies of Biological, Behavioral and Social Mechanisms Contributing to HIV Pathogenesis Within the Mission of NIDDK
Open

Funds pilot basic and translational work on HIV complications in the organs and processes the diabetes, digestive and kidney institute covers.

- pool
Mechanisms that Impact Cancer Risk with Use of Incretin Mimetics (R21)
Open

Funds smaller, higher-risk work on how GLP-1 and related drugs change cancer risk. No clinical trial in this version.

- pool
Secondary Analysis and Integration of Existing Data to Elucidate Cancer Risk and Related Outcomes (R21)
Open

Funds the same reanalysis of already-collected cancer data on a smaller, exploratory footing, for teams that do not need a full research project award.

$200K pool
Cutting-Edge Basic Research Awards (CEBRA)
Open

Funds high-risk addiction research that is sparse or absent from the institute's current portfolio โ€” a revolutionary method, or a hypothesis with no precedent.

$150K pool
NIDCD Early Career Research(ECR) Award
Open

Funds a self-contained project on hearing, balance, smell, taste, voice, speech or language by a scientist starting an independent career.

- pool
Dissemination and Implementation Research in Health (R21)
Open

Funds exploratory work on why proven health interventions do not get adopted โ€” and on stopping the ones that should be dropped.

- pool
Investigator Initiated Innovation in Computational Genomics and Data Science (R21)
Closed

Funds the exploratory version of the same computational genomics work โ€” new methods, early tools, or hardening software the field depends on.

- pool
Basic Research in Cancer Health Disparities (R21)
Open

Funds early-stage mechanistic work on the biological and genetic causes of cancer health disparities, on a shorter and smaller footing.

- pool
Developing novel theory and methods for understanding the genetic architecture of complex human traits (R21)
Open

Funds the exploratory version of the same theory-and-methods work on complex trait variation, for ideas that need testing before a larger project is justified.

- pool
Innovative Screening Approaches and Therapies for Screenable Disorders in Newborns (R21)
Open

Funds the exploratory version of the same work on screening tests and treatments for serious newborn conditions.

$200K pool
New Approaches for Measuring Brain Changes Across Longer Timespans (R21)
Open

Funds highly novel approaches to measuring brain activity, connectivity or genomics repeatedly across the lifespan, on an exploratory footing.

- pool
Development of Animal Models and Related Biological Materials for Research
Open

Funds developing or improving animal models and related materials โ€” but only where they serve several institutes and several body systems.

$200K pool
Mood and Psychosis Symptoms during the Menopause Transition (R21)
Open

Funds the exploratory version of the same translational work on mood and psychotic symptoms during the menopause transition.

- pool
Neuromodulation/Neurostimulation Device Development for Mental Health Applications (R21)
Open

Funds the exploratory version of next-generation brain stimulation device work for mental health, with the same floor on how much novelty counts.

- pool
Utilizing Invasive Recording and Stimulating Opportunities in Humans to Advance Neural Circuitry Understanding of Mental Health Disorders (R21)
Open

Funds the exploratory version of invasive human neural recording and stimulation work on mental health questions.

$200K pool
Exploratory/Developmental Bioengineering Research Grants (EBRG)
Open

Funds early feasibility work on a new biomedical tool, instrument or method that could improve research, care delivery or accessibility.

- pool
NEI Research Grant for Vision-Related Secondary Data Analysis
Open

Funds secondary analysis of vision-health data that already exists, and new statistical methods for getting more out of it.

- pool
Ethical, Legal and Social Implications (ELSI) Exploratory/Developmental Research Grant
Open

Funds exploratory studies of the ethical, legal and social consequences of human genetics, especially where a technology or a use of genomic data is new.

- pool
Expanding the Target Landscape by Drugging the Undruggable
Open

Funds early-stage work to find a method or agent that hits a human disease target considered undruggable.

- pool
Accelerating the Pace of Substance Use Research Using Existing Data (R21)
Open

Funds the exploratory R21 version of new analysis on existing social, behavioral, administrative and neuroimaging drug-use data.

- pool
Early-Stage Dissemination and Implementation Research in Communication Disorders
Open

Funds early-stage work on getting proven hearing, balance, taste, smell, voice and language treatments adopted in real clinics and daily life.

$1M pool
Using Archived Data and Specimen Collections to Advance Maternal and Pediatric HIV/AIDS Research (R21 CT Not Allowed)
Open

Funds secondary analysis of archived HIV/AIDS data and specimens from maternal, pediatric and adolescent populations, without collecting anything new.

$1M pool
INCLUDE Project: Exploratory/Developmental Research Awards for Down syndrome
Open

Funds early, exploratory Down syndrome research โ€” a novel idea or new use of an existing method, even where the answer is unproven.
