Scope of this FOA
Q1. What is a “clinical trial” for the purpose of this FOA?
A1. A clinical trial is defined by NIH (NOT-OD-15-015) as:
A research study in which one or more human subjects are prospectively assigned to one or more interventions (which may include placebo or other control) to evaluate the effects of those interventions on health-related biomedical or behavioral outcomes.
Q2. What kinds of applications are accepted for the single-site clinical trials FOA (PAR-19-328)?
A2. PAR-19-328 supports applications to develop and implement investigator-initiated single-site clinical trials. Clinical trials supported by this FOA include Phase II and above clinical trials. This FOA is applicable to single-site clinical trials only. Proposed research may utilize a design anywhere along the continuum of efficacy, comparative effectiveness, pragmatic and/or implementation research clinical trials.
Q3: What kinds of applications are NOT accepted for PAR-19-328?
A3. The following types of clinical trials are not intended to be supported by this FOA:
Q4: What is a “single-site” (as opposed to a “multi-site”) clinical trial for the purpose of this FOA?
A4. A single-site clinical trial utilizes one investigational site to conduct and coordinate the protocol. While a single-site clinical trial may enroll participants from multiple locations, participants will receive an intervention and/or undergo outcome assessments under the direction and oversight of one research team located at one investigational site.
A multi-site clinical trial involves the implementation of the same clinical protocol at two or more independent investigational sites where participants are seen for an intervention and/or outcomes assessment. In a multi-site trial, investigational sites are typically administratively or corporately distinct from each other.
Multi-site clinical trial research grant applications relevant to NHLBI’s mission must be submitted to PAR-19-329 and PAR-19-330.
Illustrative examples of single-site and multi-site clinical trials are provided in the Appendix below. Investigators with questions about whether the clinical trial that they are proposing is a single-site or multi-site clinical trial (and the FOAs that may be appropriate for their trial) are encouraged to discuss their application with an NHLBI program officer for further guidance.
Q5. What other funding opportunities can I consider if my trial does not seem to fit the single-site PAR-19-328 requirements?
A5. Consider the FOAs listed below by type of clinical trial application:
1. Pilot Studies
2. Mechanistic Clinical Trials
3. Phase I (Early Phase) Clinical Trials
4. Phase II and Beyond Multi-site Clinical Trials
Q6. I am submitting an application for research that includes both a clinical trial and a number of basic research aims. Under what circumstances would this type of project with mixed clinical and basic science research aims be appropriate for this FOA as opposed to other possible funding opportunities?
A6. This FOA is for applications for single-site studies that include Phase II and above clinical trials. Proposed research may utilize a design anywhere along the continuum of efficacy, comparative effectiveness, pragmatic and/or implementation research clinical trials. Associated research questions closely related to the aims of the clinical trial, such as understanding the intervention’s effects or the varied response of the participants to the intervention, are permitted as secondary aims.
However, if the study includes a clinical trial (1) as a method to explore fundamental mechanisms of normal biology or pathobiology, or (2) as a major precursor to, or iterative element of, a clinical study (whose design or conduct is predicated at least in part on the basic science study), then it may be more appropriate to apply for funding under the NIH parent R01 or the NHLBI P01 (see Q5 for more detail). You are encouraged to discuss your application with your program officer for further guidance.
Characteristics and Requirements of the Single-site Clinical Trials FOA
Q7. Why does NHLBI solicit applications for single-site clinical trials in Phase II and above through this FOA (and not through a parent NIH FOA)?
A7. As part of an overall strategy to optimize its clinical trials enterprise, NHLBI first modified in 2015 its FOAs for clinical trials to enhance the identification, inclusion, and application of well-defined performance milestones. This will enhance the selection of trials that are operationally feasible and promote the ability of the study team to achieve their planned objectives of the clinical trial within the 5 year timeframe and budget at a single site. Performance milestones are to be identified by the investigators to establish expectations regarding trial performance and will be peer-reviewed. Milestones must be performance-based to achieve completion of the trial on time and on budget, and must be established for both the R61 and R33 phases of the project.
Q8. Why are detailed milestones and metrics important for single-site trials, which are typically less complex and easier to manage than multi-site clinical trials?
A8. Although single-site clinical trials are, in general, operationally less complex than multi-site clinical trials, they still benefit from careful planning, including the identification of milestones and metrics that promote the successful conduct of the trial.
Q9. What notable characteristics are in the NHLBI FOA for single-site clinical trials?
A9. Some of the more notable characteristicss include:
Q10. What are the major differences in this reissue (PAR-19-328) of the FOA as compared to the earlier issuance (PAR-18-406)?
A10. Major differences include:
Q11. What personnel experience should be included in the Clinical Trial Research Experience attachment?
A11. Information can be provided within 3 pages on all key personnel with relevant experience, including but not limited to the PD/PI, MPI or co-investigators.
Q12. What funding mechanism is being used to support trials under this FOA?
A12. Applications awarded under this FOA will be funded through a biphasic investigator-initiated award. The first phase will be an R61 (Phase 1 Exploratory/Developmental Grant), which is used to prepare for initiation of the trial. That award is for up to one year. The second phase, conditional on a positive evaluation through an administrative review of the first phase, will be an R33 (Exploratory/Developmental Grants Phase II), which will provide support for the conduct of the clinical trial. The R33 phase award can be for up to 4 years.
Application and Review Process
Q13. Will the process for requesting a ≥500K budget be the same for this PAR?
A13. Yes. The NHLBI policy for applications for >500K apply to application submitted to PAR-19-328 (or its reissues). Please refer the instructions on the NHLBI >500K website (hyperlink)
Q14. Under what conditions will an application advance from the R61 to the R33 phase?
A14. At 9 months into the R61 phase, NHLBI will administratively review progress and extent to which peer-reviewed milestones are met in the R61 phase, including:
In addition, all necessary drugs, devices, or other resources as needed are to be obtained during this period. The extent to which the milestones have been met and the trial is poised to be conducted successfully will determine whether the R33 phase award will be issued, subject to NHLBI funding availability. The awardee will be able to share milestone completion progress through eConnect, an NHLBI platform that will facilitate transfer of electronic information to NHLBI
Q15. At what point in time during the R61 award period will investigators know that the administrative review of that phase was successful and their R33 phase will be awarded?
A15. The administrative review will typically occur at about 9 months into the 12-month R61 award. It is anticipated that the review will be completed, and investigators will be notified whether the R33 phase will be awarded at about 10 or 11 months into the R61 award.
Q16. Is the administrative review a competitive one? That is, will more R61 awards be made than can be supported through the R33 phase?
A16. No, this is not NHLBI’s intent. The Institute will fund the R33 phase provided that the administrative review indicates successful completion of the first phase (R61). That determination would be made independently of how other trials fared in the administrative review of their R61 phase.
Q17. I am an investigator at an institution outside the United States. Am I eligible to apply for awards under this FOA?
A17. Yes. Institutions outside the United States are eligible to apply for these awards, as are applications with foreign components.
After the Clinical Trial is Funded
Q18. What if unanticipated events occur after I am funded that necessitate changing the timing or nature of my clinical trial milestones? Is that allowed? If so, what do I do?
A18. In general, NHLBI does not expect there will be changes to Core Milestones. It is expected that the peer-reviewed milestones will be completed as planned. However, if an unanticipated event necessitates changing any of your milestones or impacts the study timeline, then you should contact the NHLBI program official as soon as possible to discuss this development. The program official will work with you to determine whether changes are warranted and, if so, how they may be implemented.
Q19. Are there any circumstances under which a single site trial funded under this FOA may add performance sites?
A19. Yes, but these are limited and should be discussed with your program official. You may be able to add a performance site if:
If these criteria are not met, you will not be able to add a performance site. If adding an additional site is not appropriate, your program official will evaluate whether the best course of action is to (1) complete the study as originally designed, or (2) if the original research aims cannot be achieved, have you reapply under the NHLBI FOA for multi-site clinical trials. If an additional site is deemed appropriate under the current award, this modification will have to be formally approved by NHLBI and reflected in a revised Notice of Grant Award.
Q20. Are there changes to the CCC or DCC applications resulting from the change to FORMS-F?
A20: Yes, in the Human Studies & Clinical Trials Information of the CCC -- Section 4: Protocol Synopsis -- no longer requires a “Brief Summary”. Due to this change the numbering of all subsection changed slightly and in the Study Design of both the CCC and DCC, the “Narrative Study Description” has been replaced by the “Detailed Description” (4.1.a). All instructions in the FOAs apply.
