This specific announcement may be closed or reissued, but its review criteria — and the applications that won — are the durable lesson. Here is what reviewers score, and what funded applications looked like.
The scored review criteria for PAR-23-297, as published in the funding announcement.
Section V. Application Review Information 1. Criteria Only the review criteria described below will be considered in the review process. Applications submitted to the NIH in support of the NIH mission are evaluated for scientific and technical merit through the NIH peer review system. For this particular announcement, note the following:This R01 initiative supports investigation of novel scientific ideas or new interventions at the start of cART that have the potential for a sustained remission. Accordingly, reviewers will emphasize the conceptual framework, the level of innovation, and the potential to significantly advance our knowledge or understanding. Overall Impact Reviewers will provide an overall impact score to reflect their assessment of the likelihood for the project to exert a sustained, powerful influence on the research field(s) involved, in consideration of the following review criteria and additional review criteria (as applicable for the project proposed). Scored Review Criteria Reviewers will consider each of the review criteria below in the determination of scientific merit and give a separate score for each. An application does not need to be strong in all categories to be judged likely to have major scientific impact. For example, a project that by its nature is not innovative may be essential to advance a field. Significance Does the project address an important problem or a critical barrier to progress in the field? Is the prior research that serves as the key support for the proposed project rigorous? If the aims of the project are achieved, how will scientific knowledge, technical capability, and/or clinical practice be improved? How will successful completion of the aims change the concepts, methods, technologies, treatments, services, or preventative interventions that drive this field? Specific to this NOFO:How suitable is the proposed cure intervention for administration concomitantly with cART? Investigator(s) Are the PD(s)/PI(s), collaborators, and other researchers well suited to the project? If Early Stage Investigators or those in the early stages of independent careers, do they have appropriate experience and training? If established, have they demonstrated an ongoing record of accomplishments that have advanced their field(s)? If the project is collaborative or multi-PD/PI, do the investigators have complementary and integrated expertise; are their leadership approach, governance, and organizational structure appropriate for the project? Specific to this NOFO:To what degree does the interdisciplinary team bring unique strategies to the project? If applicable, how well integrated into the team are the private sector and/or animal models expertise? Innovation Does the application challenge and seek to shift current research or clinical practice paradigms by utilizing novel theoretical concepts, approaches or methodologies, instrumentation, or interventions? Are the concepts, approaches or methodologies, instrumentation, or interventions novel to one field of research or novel in a broad sense? Is a refinement, improvement, or new application of theoretical concepts, approaches or methodologies, instrumentation, or interventions proposed? Specific to the NOFO:To what extent are the proposed HIV cure strategies at the time of cART initiation or restart novel to the HIV field? If applicable, how appropriate is the rationale for the use of HIV cure strategies that have been re-purposed from a different field? If new technologies are being employed, how well will the decay of intact, replication-competent HIV at the start of cART be addressed? Approach Are the overall strategy, methodology, and analyses well-reasoned and appropriate to accomplish the specific aims of the project? Have the investigators included plans to address weaknesses in the rigor of prior research that serves as the key support for the proposed project? Have the investigators presented strategies to ensure a robust and unbiased approach, as appropriate for the work proposed? Are potential problems, alternative strategies, and benchmarks for success presented? If the project is in the early stages of development, will the strategy establish feasibility and will particularly risky aspects be managed? Have the investigators presented adequate plans to address relevant biological variables, such as sex, for studies in vertebrate animals or human subjects? If the project involves human subjects and/or NIH-defined clinical research, are the plans to address 1) the protection of human subjects from research risks, and 2) as required by statute, inclusion (or exclusion) of individuals on the basis of sex, race, and ethnicity, as well as the inclusion or exclusion of individuals of all ages (including children and older adults), justified in terms of the scientific goals and research strategy proposed? Specific to this NOFO:To what extent do the scientific literature cited, data sources, or other inferential data support the potential to increase understanding of means to reduce HIV persistence? If applicable, how well are the specific unique considerations for use of long-acting formulations of cART and/or HIV cure interventions addressed? How feasible are the proposed HIV cure strategies that are employed early after HIV/SIV/SHIV infection, within one month of cART, or administered during an ATI? How translatable is the study design to clinical trials? To what degree is the study design, including randomization, sufficiently powered to interpret the results and how adequate are the proposed endpoints to evaluate the study outcome? To what extent have synergistic efficacy or toxicities with cART been considered? If animal studies are proposed to what degree are the studies well integrated into the program overall? Environment Will the scientific environment in which the work will be done contribute to the probability of success? Are the institutional support, equipment, and other physical resources available to the investigators adequate for the project proposed? Will the project benefit from unique features of the scientific environment, subject populations, or collaborative arrangements? Specific to this NOFO:If applicable, how strong is the evidence that sufficient numbers of nonhuman primates (NHPs) will be available to the investigators for the proposed studies? Additional Review Criteria As applicable for the project proposed, reviewers will evaluate the following additional items while determining scientific and technical merit, and in providing an overall impact score, but will not give separate scores for these items. Protections for Human Subjects For research that involves human subjects but does not involve one of the categories of research that are exempt under 45 CFR Part 46, the committee will evaluate the justification for involvement of human subjects and the proposed protections from research risk relating to their participation according to the following five review criteria: 1) risk to subjects, 2) adequacy of protection against risks, 3) potential benefits to the subjects and others, 4) importance of the knowledge to be gained, and 5) data and safety monitoring for clinical trials.For research that involves human subjects and meets the criteria for one or more of the categories of research that are exempt under 45 CFR Part 46, the committee will evaluate: 1) the justification for the exemption, 2) human subjects involvement and characteristics, and 3) sources of materials. For additional information on review of the Human Subjects section, please refer to the Guidelines for the Review of Human Subjects. Inclusion of Women, Minorities, and Individuals Across the Lifespan When the proposed project involves human subjects and/or NIH-defined clinical research, the committee will evaluate the proposed plans for the inclusion (or exclusion) of individuals on the basis of sex, race, and ethnicity, as well as the inclusion (or exclusion) of individuals of all ages (including children and older adults), as required by statute, to determine if it is justified in terms of the scientific goals and research strategy proposed. For additional information on review of the Inclusion section, please refer to the Guidelines for the Review of Inclusion in Clinical Research. Vertebrate Animals The committee will evaluate the involvement of live vertebrate animals as part of the scientific assessment according to the following criteria: (1) description of proposed procedures involving animals, including species, strains, ages, sex, and total number to be used; (2) justifications for the use of animals versus alternative models and for the appropriateness of the species proposed; (3) interventions to minimize discomfort, distress, pain and injury; and (4) justification for euthanasia method if NOT consistent with the AVMA Guidelines for the Euthanasia of Animals.
