Assistance Listing Number(s) Funding Opportunity Purpose This notice of funding opportunity (NOFO) will support pilot, feasibility or exploratory research in priority areas in substance use epidemiology, prevention, and health services, including: 1) Research in response to sudden and severe emerging drug issues (e.g. the ability to look into a large and sudden spike in opioid or synthetic cannabinoid use/overdoses in a particular community); 2) Research in response to emerging trends and topics related to a change in federal, state, or local drug policy.

The work proposed must be related to imminent policy change; 3) Research in response to unexpected and time-sensitive medical system issues (e.g. opportunities to understand addiction services in the evolving health care system); 4) Responses to unexpected and time-sensitive criminal or juvenile justice opportunities (e.g. new system and/or structural level changes) that relate to drug misuse and access and provision of health care service; 5) Research that examines the early implementation of new or newly changed federal, state, or local programs, policy, financing, or payment approaches related to substance use, substance use epidemiology, prevention, treatment, or recovery.

Activities may include infrastructure-building partnerships among researchers and state or local organizations to address later implementation phases; 6) Research in response to natural disasters or newly emergent public health emergencies, to understand their impacts on drug markets, substance use epidemiology, prevention, treatment or recovery outcomes.

For the purposes of this NOFO, “time-sensitive” is defined as in need of expedited review and funding in order to answer the scientific research question(s) posed (e.g. an imminent policy change will not allow for standard review and funding timeline). Applications whose aims can be accomplished with standard NIH submission, review, and award cycles will not be considered time-sensitive.

Open Date (Earliest Submission Date) Renewal / Resubmission / Revision (as allowed) AIDS - New/Renewal/Resubmission/Revision, as allowed All applications are due by 5:00 PM local time of applicant organization. Applicants are encouraged to apply early to allow adequate time to make any corrections to errors found in the application during the submission process by the due date.

Notice of Funding Opportunity Description This notice of funding opportunity (NOFO) will support pilot, feasibility or exploratory research in priority areas in substance use epidemiology, prevention, and health services, including: 1) Research in response to sudden and severe emerging drug issues (e.g. the ability to look into a large and sudden spike in opioid or synthetic cannabinoid use/overdoses in a particular community); 2) Research in response to emerging trends and topics related to a change in federal, state, or local drug policy.

The work proposed must be related to imminent policy change; 3) Research in response to unexpected and time-sensitive medical system issues (e.g. opportunities to understand addiction services in the evolving health care system); 4) Responses to unexpected and time-sensitive criminal or juvenile justice opportunities (e.g. new system and/or structural level changes) that relate to drug misuse and access and provision of health care service; 5) Research that examines the early implementation of new or newly changed federal, state, or local programs, policy, financing, or payment approaches related to substance use, substance use epidemiology, prevention, treatment, or recovery.

Activities may include infrastructure-building partnerships among researchers and state or local organizations to address later implementation phases; 6) Research in response to natural disasters or newly emergent public health emergencies, to understand their impacts on drug markets, substance use epidemiology, prevention, treatment or recovery outcomes.

This NOFO responds to the need for rapid responses to emerging policy changes and phenomena that affect the delivery and/or effectiveness of prevention and treatment services related to addiction care (in particular prescription drug use), HIV care, and the criminal justice setting. The NOFO provides a mechanism for accelerated review and award to support opportunities for this type of initial feasibility and pilot research.

In particular, this NOFO encourages innovative scientific partnerships between researchers and community or public partners (e.g., local departments of health, poison centers, medical examiners, health care providers; public mental health/substance use or health care systems; public and federally-charted community health clinic settings; criminal justice settings; school systems; child welfare agencies; long-term care providers, payers, health authorities, etc.) who confront urgent substance-related health crises or who cannot delay policy or program changes in order to obtain baseline research data related to the implementation or impact of such changes.

For example, this could include research collaborations intended to answer pressing or innovative questions presented by acute and rapidly changing dynamics in substance use and/or rapid changes in health care, justice system policy, or system structure.

It is expected that applications to this NOFO will tend to focus on a particular locality, but will have the ability to demonstrate that findings from the proposed time sensitive research have the potential to generalize beyond the locality and provide insights at a broader level.

Definition of “time-sensitive”: For the purposes of this NOFO, “time-sensitive” is defined as in need of expedited review and funding in order to answer the scientific research question(s) posed (e.g. an imminent policy change will not allow for standard review and funding timeline). To be responsive to this NOFO, it should be clear that the knowledge gained from the proposed study is time-sensitive according to the definition above.

Applications whose aims can be accomplished with standard NIH submission, review, and award cycles , or have not provided sufficient time-sensitive justification will be considered nonresponsive and not reviewed.

IMPORTANT NOTE : All potential applicants are encouraged to consult with the Scientific/Research contact 4 weeks in advance of the submission date to determine the National Institute on Drug Abuse (NIDA)'s interest in support under this NOFO for time-sensitive research in one or more of the priority areas outlined above, and to provide a justification for responsiveness to the time-sensitive aspect of this NOFO (as defined above).

All eligible applications responding to this NOFO will be subject to an accelerated review and award process. It is intended that eligible applications selected for funding will be awarded within 6 months after the application due date. However, administrative requirements and other unforeseen circumstances may delay issuance dates beyond that timeline.

Applications Not Responsive to this NOFO The following types of studies are not responsive to this NOFO and will not be reviewed: Applications that do not meet the definition of “time-sensitive” noted above. Applications that include alcohol alone as a substance of use. Applications that do not address a need requiring rapid responses.

Post Submission Materials Applicants are required to follow the instructions for post-submission materials, as described in the policy Section V. Application Review Information 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.

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). An application does not need to be strong in all categories to be judged likely to have a major scientific impact.

Reviewers will consider Factors 1, 2 and 3 in the determination of scientific merit, and in providing an overall impact score. In addition, Factors 1 and 2 will each receive a separate factor score. Factor 1: Importance of the Research Evaluate the importance of the proposed research in the context of current scientific challenges and opportunities, either for advancing knowledge within the field, or more broadly.

Assess whether the application addresses an important gap in knowledge in the field, would solve a critical problem, or create a valuable conceptual or technical advance. Evaluate the rationale for undertaking the study, the rigor of the scientific background for the work (e.g. prior literature and/or preliminary data) and whether the scientific background justifies the proposed study.

Evaluate the extent to which innovation influences the importance of undertaking the proposed research. Note that while technical or conceptual innovation can influence the importance of the proposed research, a project that is not applying novel concepts or approaches may be of critical importance for the field.

Evaluate whether the proposed work applies novel concepts, methods or technologies, or uses existing concepts, methods, technologies in novel ways, to enhance the overall impact of the project. Factor 2. Rigor and Feasibility Evaluate the scientific quality of the proposed work.

Evaluate the likelihood that compelling, reproducible findings will result (rigor) and assess whether the proposed studies can be done well and within the timeframes proposed (feasibility). Evaluate the potential to produce unbiased, reproducible, robust data. Evaluate the rigor of experimental design and whether appropriate controls are in place.

Evaluate whether the sample size is sufficient and well-justified. Assess the quality of the plans for analysis, interpretation, and reporting of results. Evaluate whether the investigators presented adequate plans to address relevant biological variables, such as sex or age, in the design, analysis, and reporting.

For applications involving human subjects or vertebrate animals, also evaluate: the rigor of the intervention or study manipulation (if applicable to the study design). whether outcome variables are justified. whether the results will be generalizable or, in the case of a rare disease/special group, relevant to the particular subgroup.

whether the sample is appropriate and sufficiently diverse to address the proposed question(s). For applications involving human subjects, including clinical trials, assess the adequacy of inclusion plans as appropriate for the scientific goals of the research.

Considerations of appropriateness may include disease/condition/behavior incidence, prevalence, or population burden, population representation, and/or current state of the science. Evaluate whether the proposed approach is sound and achievable, including plans to address problems or new challenges that emerge in the work.

For proposed studies in which feasibility may be less certain, evaluate whether the uncertainty is balanced by the potential for major advances. For applications involving human subjects, including clinical trials, evaluate the adequacy and feasibility of the plan to recruit and retain an appropriately diverse population of participants.

Additionally, evaluate the likelihood of successfully achieving the proposed enrollment based on age, race, ethnicity, and sex. For clinical trial applications, evaluate whether the study timeline and milestones are feasible. Factor 3.

Expertise and Resources Evaluate whether the investigator(s) have demonstrated background, training, and expertise, as appropriate for their career stage, to conduct the proposed work. For Multiple Principal Investigator (MPI) applications, assess the quality of the leadership plan to facilitate coordination and collaboration.

Evaluate whether the institutional resources are appropriate to ensure the successful execution of the proposed work. 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, 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, 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 .

When the proposed research includes Vertebrate Animals, evaluate the involvement of live vertebrate animals 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.

For additional information on review of the Vertebrate Animals section, please refer to the Worksheet for Review of the Vertebrate Animals Section . When the proposed research includes Biohazards, evaluate whether specific materials or procedures that will be used are significantly hazardous to research personnel and/or the environment, and whether adequate protection is proposed.

For Revisions, the committee will consider the appropriateness of the proposed expansion of the scope of the project.

If the Revision application relates to a specific line of investigation presented in the original application that was not recommended for approval by the committee, then the committee will consider whether the responses to comments from the previous scientific review group are adequate and whether substantial changes are clearly evident.

Additional Review Considerations As applicable for the project proposed, reviewers will consider each of the following items, but will not give scores for these items, and should not consider them in providing an overall impact score.

Authentication of Key Biological and/or Chemical Resources: For projects involving key biological and/or chemical resources, evaluate the brief plans proposed for identifying and ensuring the validity of those resources. Budget and Period of Support Evaluate whether the budget and the requested period of support are fully justified and reasonable in relation to the proposed research. 2.

Review and Selection Process Applications will be evaluated for scientific and technical merit by (an) appropriate Scientific Review Group(s) convened by NIDA, in accordance with NIH peer review policy and procedures , using the stated review criteria . Assignment to a Scientific Review Group will be shown in the eRA Commons. As part of the scientific peer review, all applications will receive a written critique.

Applications may undergo a selection process in which only those applications deemed to have the highest scientific and technical merit (generally the top half of applications under review) will be discussed and assigned an overall impact score. Applications will be assigned on the basis of established PHS referral guidelines to the appropriate NIH Institute or Center.

Applications will compete for available funds with all other recommended applications. Following initial peer review, recommended applications will receive a second level of review by
