Know What Funding Opportunities Are Available

In alignment with NIH efforts to enhance stewardship over clinical trials, NIDCD has redefined the scope of R01 and U01 clinical trials applications to address risks in terms of safety, complexity, fiscal investment, and direct scientific/public health impact. The cooperative agreement U01 mechanism continues to be most appropriate for higher-risk clinical trials, which will benefit from the substantial scientific and programmatic involvement of an NIDCD Project Scientist. The Project Scientist will provide scientific/technical expertise and, in partnership with the Principal Investigator (PI), will be involved in protocol development; study implementation; and ensuring timely progress, protocol adherence, data quality, and participant safety.

NIDCD has two primary funding opportunities for clinical trials.

Stand-alone independent clinical trials cannot be proposed as part of the research plan in a fellowship (F) application. See NIDCD Fellowships: Frequently Asked Questions for details.

The risk criteria for applying to the R01 or U01 mechanism are below:

Award TypeR01    
(if ALL of the criteria below are met)
(if ANY of the criteria below are met)
FDA oversight of the interventionDoes not require FDA oversight, e.g., for investigational new drug (IND) or investigational device exemption (IDE) applications. Example: clinical trials involving use of a licensed product/device for an approved dose, population, and indication may not require an IND or IDE.Requires FDA oversight, e.g., for investigational new drug (IND) or investigational device exemption (IDE) applications.
Anticipated risks to participantsPotential of the intervention to have safety risks to participants is low. Example: risks that are no greater than those encountered in routine medical care or procedures.

Has the potential to have higher safety risks to participants, for example:

  • Use of a non-routine intervention.
  • Use of an unlicensed product/device, e.g., does not have FDA approval.
  • Use of a licensed product/device for an unapproved indication or unapproved population, e.g., not within the FDA approved product label.
Study goalsIntends to gather scientific data/evidence to inform subsequent studies, but is not aimed or sufficiently powered to directly change health policy or standard of care and is not an NIH-defined Phase III clinical trial.NIH-defined Phase III clinical trial:    
An NIH-defined Phase III clinical trial is a broadly-based, prospective Phase III clinical investigation, usually involving several hundred or more human subjects, for the purpose of evaluating an experimental intervention in comparison with a standard or controlled intervention or comparing two or more existing treatments. Often the aim of such investigation is to provide evidence leading to a scientific basis for consideration of a change in health policy or standard of care. The definition includes pharmacologic, non-pharmacologic, and behavioral interventions given for disease prevention, prophylaxis, diagnosis, or therapy. Community trials and other population-based intervention trials are also included.
Annual direct costsApplication budgets are limited to less than $500,000 in direct costs in any year.Applications exceeding the annual direct costs of $700,000 or more, in certain cases, may also be a criterion.
