The scored review criteria for PAR-21-130, as published in the funding announcement.

Section V. Application Review Information 1. Criteria Note: Effective for due dates on or after January 25, 2023, the Data Sharing Plan and Genomic Data Sharing Plan (GDS) as part of the Resource Sharing Plan will not be evaluated at time of review. 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. A proposed Clinical Trial application may include study design, methods, and intervention that are not by themselves innovative but address important questions or unmet needs. Additionally, the results of the clinical trial may indicate that further clinical development of the intervention is unwarranted or lead to new avenues of scientific investigation. 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? Does the application justify significance of the research in terms of the practical effect of the intervention or service approach that is being studied and the estimated hypothesized effect size (in terms of key outcomes, such as clinical benefit, safety/tolerability, value and efficiency, or scalability), compared with already available approaches? Does the application adequately address both (1) the empirical basis for the anticipated effect size (e.g., citing data regarding the magnitude of the association between the target and the clinical endpoint of interest and/or effect sizes obtained in prior efficacy studies), and (2) the clinical meaningfulness of the anticipated increment in effects compared to existing approaches? If the approach is successful, is it scalable and could it be disseminated into practice given typically available resources (e.g., trained, skilled providers), typical service structures (including health care financing), and typical service use patterns? Are the scientific rationale and need for a clinical trial to test the proposed hypothesis or intervention well supported by preliminary data, clinical and/or preclinical studies, or information in the literature or knowledge of biological mechanisms? For trials focusing on clinical or public health endpoints, is this clinical trial necessary for testing the safety, efficacy or effectiveness of an intervention that could lead to a change in clinical practice, community behaviors or health care policy? For trials focusing on mechanistic, behavioral, physiological, biochemical, or other biomedical endpoints, is this trial needed to advance scientific understanding? 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? With regard to the proposed leadership for the project, do the PD/PI(s) and key personnel have the expertise, experience, and ability to organize, manage and implement the proposed clinical trial and meet milestones and timelines? Do they have appropriate expertise in study coordination, data management and statistics? For a multicenter trial, is the organizational structure appropriate and does the application identify a core of potential center investigators and staffing for a coordinating center? 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? As relevant, evaluate the extent to which applications of technology (e.g., digital health or mhealth approaches) or other innovative approaches are leveraged to facilitate the conduct of the research project (e.g., use of Electronic Health Records or other administrative data to facilitate participant identification, data collection) and/or to increase the reach, efficiency, or effectiveness of the intervention or service delivery strategy that is being evaluated. Examples of innovative elements could include adaptive sequential randomization, equipoise stratification, or technology assisted assessment and others. Does the design/research plan include innovative elements, as appropriate, that enhance its sensitivity, potential for information or potential to advance scientific knowledge or clinical practice? 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) inclusion (or exclusion) of individuals on the basis of sex/gender, 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? How well does the study design address whether the intervention engages the mechanism that is presumed to underlie the intervention effects (the mechanism that accounts for changes in clinical/ functional outcomes, changes in provider behavior, etc.)? To what extent does the application include (1) a well-supported conceptual framework that clearly identifies the target(s)/mechanism(s) and the empirical evidence linking the target(s)/mechanism(s) to the clinical symptoms, functional deficits, or patient-, provider- or system-level behaviors/processes that the intervention seeks to improve; (2) well justified plans for assessing engagement of the target(s)/mechanism(s), including the specific measures, the assessment schedule, and the justification for the assessment strategy (e.g., evidence regarding the validity and feasibility of the proposed measures in the effectiveness context); and (3) an appropriate analytic strategy and corresponding power calculations for data analyses that will be used to examine whether the intervention engages the target(s) and whether intervention-induced changes in the target(s) are associated with and account for clinical benefit (i.e., mediation)? Is the study sufficiently powered to examine mediators of intervention effects? In the case of multi-component interventions, does the application specify the conceptual basis, assessment plan, and analytic strategy, as detailed above, for the target(s)/mechanism(s) corresponding to each intervention component, as appropriate in the effectiveness context? When appropriate, for studies that involve preventive or therapeutic interventions, does the study take into account RDoC or RDoC-like constructs when defining the subject eligibility (inclusion), intervention targets or mechanisms, and outcomes, as feasible in the effectiveness setting? Does the application include provisions for the assessment and monitoring of the fidelity of intervention delivery via procedures that are feasible and valid for use in community practice settings? To what extent does the approach incorporate design features that will help ensure that the intervention can be feasibly implemented in practice, that it is scalable, and that it is robust against implementation drift (e.g., using technology as scaffolding or expert consultation via existing resources/ other sustainable means to support delivery), as appropriate? Evaluate the plans to involve collaborations and/or input from community practice partners/providers, consumers, and relevant policy makers in a manner that informs the research (e.g., to help ensure the interventions/service delivery approaches are acceptable, feasible, and scalable) and helps to ensure the results will have utility. To what extent does the application include plans to assess and examine consumer-, provider- and setting- level factors that might be associated with uptake, implementation fidelity, and sustained use of the approach that is being developed and tested? How well does the application describe the provider- and setting- level characteristics that will be assessed and the measures that will be used (e.g., standardized measures of provider attitudes/experience, clinic-/organizational characteristics)? Are proposed outcome measures validated and generally accepted by the field; are stakeholder-relevant outcomes included, as appropriate (e.g., functioning, health services use)? Are the trial design and description of the research protocol consistent with CONSORT guidelines, as appropriate? How likely is it that the trial will contribute to advancing the personalization of mental health care? Does it include collection of clinical and biological variables (e.g., blood for genetic analysis, other potential biomarkers), as appropriate, that might be used to inform or test algorithms for more prescriptive approaches? Will the study have either adequate statistical power to test for moderators or the potential to contribute information to larger databases for future use? Does the application adequately address the following, if applicable Study Design Is the study design justified and appropriate to address primary and secondary outcome variable(s)/endpoints that will be clear, informative and relevant to the hypothesis being tested? Is the scientific rationale/premise of the study based on previously well-designed preclinical and/or clinical research? Given the methods used to assign participants and deliver interventions, is the study design adequately powered to answer the research question(s), test the proposed hypothesis/hypotheses, and provide interpretable results? Is the trial appropriately designed to conduct the research efficiently? Are the study populations (size, gender, age, demographic group), proposed intervention arms/dose, and duration of the trial, appropriate and well justified? Are potential ethical issues adequately addressed? Is the process for obtaining informed consent or assent appropriate? Is the eligible population available? Are the plans for recruitment outreach, enrollment, retention, handling dropouts, missed visits, and losses to follow-up appropriate to ensure robust data collection? Are the planned recruitment timelines feasible and is the plan to monitor accrual adequate? Has the need for randomization (or not), masking (if appropriate), controls, and inclusion/exclusion criteria been addressed? Are differences addressed, if applicable, in the intervention effect due to sex/gender and race/ethnicity? Are the plans to standardize, assure quality of, and monitor adherence to, the trial protocol and data collection or distribution guidelines appropriate? Is there a plan to obtain required study agent(s)? Does the application propose to use existing available resources, as applicable? Data Management and Statistical Analysis Are planned analyses and statistical approach appropriate for the proposed study design and methods used to assign participants and deliver interventions? Are the procedures for data management and quality control of data adequate at clinical site(s) or at center laboratories, as applicable?
