Funding Opportunity RFA-ES-25-003 from the NIH Guide for Grants and Contracts. This Notice of Funding Opportunity (NOFO) is intended to support novel environmental health research in which an unpredictable event or policy change provides a limited window of opportunity to collect human biological samples or environmental exposure data. The primary motivation of the NOFO is to understand the consequences of natural and human-made disasters, emerging environmental public health threats, and policy changes in the U.S. and abroad. A distinguishing feature of an appropriate study is the need for rapid review and funding, substantially shorter than the typical NIH grant review/award cycle, for the research question to be addressed and swiftly implemented. The shortened timeframe will be achieved by more frequent application due dates and expediting peer review, council concurrence and award issuance. The entire cycle, from submission to award, is expected to be within 4-6 months.

Funding Opportunity RFA-AG-24-049 from the NIH Guide for Grants and Contracts. This NOFO invites applications that apply existing or newly developed artificial intelligence and machine learning methods (AI/ML) to various aspects of drug discovery and preclinical drug development to accelerate the identification, optimization, and selection of preclinical drug candidates for the treatment and prevention of Alzheimers disease (AD) and AD-related dementias ADRD and increase their likelihood of success during clinical drug development.This program will also create advanced open-source analytical tools that will be made available to researchers in academia and biotech/pharma for more effective prosecution of AD/ADRD drug discovery campaigns for novel targets.

Funding Opportunity PAR-25-188 from the NIH Guide for Grants and Contracts. The purpose of this Notice of Funding Opportunity (NOFO) is to encourage UG3/UH3 phased cooperative agreement research applications to plan and implement behavioral and social intervention clinical trials. Studies appropriate for this announcement include clinical trials to develop and test behavior change interventions related to dental, oral, or craniofacial conditions. Awards made under this FOA will initially support a milestone-driven planning phase (UG3) for up to 2 years, with possible transition to a clinical trial implementation phase (UH3) of up to five years. Only UG3 projects that have met the scientific milestones and feasibility requirements may transition to the UH3 phase. The UG3/UH3 application must be submitted as a single application, following the instructions described in this FOA. The UG3 phase will permit both scientific and operational planning activities. Scientific planning activities include small-scale data collection to assess the feasibility and/or acceptability of a planned behavioral or social intervention and associated study procedures (e.g., acceptability of study content or mode of delivery; feasibility of proposed data collection procedures; preliminary testing of intervention training and fidelity monitoring procedures). Operational planning activities include, at a minimum, development of: the final clinical protocol; the intervention manual or equivalent; the data management system and other tools for data and quality management, safety and operational oversight plans; recruitment and retention strategies; and other essential documents. The UH3 phase will support the conduct of investigator-initiated intervention research at all stages, from early mechanistic research and intervention development (e.g., Stages 0/ I) through implementation and cost-effectiveness research (Stages IV/V).

Pre-exposure prophylaxis, also known as PrEP, is a safe, highly effective medication for preventing transmission of HIV from sex or injection drug use. Despite PrEPs high efficacy and its availability for over a decade, the awareness, uptake, and adherence of PrEP, especially among people who use substances remain suboptimal. The goal of this concept is to support research to examine and address systemic and structural factors that impede or facilitate the PrEP awareness, uptake, and adherence, among people who use substances. Projects will develop, implement, and evaluate effective strategies that meet the needs of people who use substances to improve the PrEP care continuum.

Funding Opportunity PAR-25-271 from the NIH Guide for Grants and Contracts. This Notice of Funding Opportunity (NOFO) encourages applications for investigator-initiated mid-phase clinical trials of natural products(i.e., botanicals, dietary supplements, and probiotics), which have a strong scientific premise to justify further clinical testing. For this NOFO, natural products include promising nutritional regimens that standardize the amount of a specific naturally occurring nutritional compound (e.g., omega-3 fatty acids, anthocyanidins, or polyphenols) and have compelling preliminary evidence. All applications submitted under this NOFO must be supported by sufficient preliminary data demonstrating bioavailability (if applicable) and documentation that the natural product produces a reproducible and measurable impact on target engagement (i.e., measure of the mechanism of action). Only in cases when it is not possible/practical to measure target engagement in the patient population of interest or when there is a fundamental understanding of the products mechanism of action will this preliminary data requirement be waived. Applications submitted to this NOFO should propose a mid-phase clinical trial to do the following: determine the optimal dose or formulation of a given natural product for use in a future multi-site efficacy trial; or determine which patient phenotypes will be responders versus non-responders to the natural product to inform inclusion/exclusion criteria of a future efficacy trial. Clinical trials submitted under this NOFO are expected to be hypothesis based, milestone-driven, and directly related to the research priorities and mission of NCCIH. This NOFO will not support single-site or multi-site efficacy or effectiveness trials, nor will it support trials to test natural products for the treatment or prevention of cancer. Applicants are encouraged to contact the appropriate NCCIH Scientific/Research contact for the area of science for which they are planning to develop an application prior to submitting to this NO

Funding Opportunity PAR-25-270 from the NIH Guide for Grants and Contracts. This Notice of Funding Opportunity (NOFO) encourages applications for investigator-initiated, early phase, clinical trials of natural products (i.e., botanicals, dietary supplements, and probiotics), which have a strong scientific premise to justify further clinical testing. For this NOFO, natural products include promising nutritional regimens that standardize the amount of a specific naturally occurring nutritional compound (e.g., omega-3 fatty acids, anthocyanidins, or polyphenols) and have compelling preliminary evidence. Under this NOFO, trials must be designed so that results, whether positive or negative, will provide information of high scientific utility and will support decisions about further development or testing of the natural product. This NOFO will provide up to 3 years support for studies to replicate the impact of the natural product on target engagement when used by humans, and assess whether there is an association between the degree of the impact on target engagement and functional or clinical outcomes in a patient population. Applications are encouraged to design studies to determine how to optimize the impact of the natural product on target engagement by optimizing the delivery of the natural product through examination of different doses or formulations. In addition, applications can be designed to combine the natural product with another treatment approach that is known to engage the same target; or study the impact of the natural product in a target population that is more responsive. Clinical trials submitted under this NOFO are expected to be hypothesis based, milestone-driven, and directly related to the research priorities and mission of NCCIH. This R33 funding mechanism is intended to accelerate the translation of emerging basic science findings about natural products into early-stage clinical testing to determine whether continued clinical research is warranted. This NOFO will not support efficacy or effectiveness trials, nor will

Funding Opportunity PAR-25-269 from the NIH Guide for Grants and Contracts. This Notice of Funding Opportunity (NOFO) encourages applications for investigator-initiated, early phase, clinical trials of natural products (i.e., botanicals, probiotics, and products marketed as dietary supplements), which have a strong scientific premise to justify further clinical testing. For this NOFO, natural products include promising nutritional regimens that standardize the amount of a specific naturally occurring nutritional compound (e.g., omega-3 fatty acids, anthocyanidins, or polyphenols) and have compelling preliminary evidence. Under this NOFO, trials must be designed so that results, whether positive or negative, will provide information of high scientific utility and will support decisions about further development or testing of the natural product. This NOFO will provide up to three years (R61 phase) of support for milestone-driven testing of pharmacokinetics, bioavailability, and assessment of the natural products effect (i.e., measure of mechanism of action) when used by humans on a specified target measure. If milestones in the R61 phase are achieved, up to 3 years of additional support (R33 phase) may be awarded to replicate the impact of the natural product on target engagement(s) when used by humans and assess whether there is an association between the degree of the impact on the target engagement and clinical outcomes in a participant population. Applications are encouraged to design R33 studies to determine how to optimize the impact of the natural product on the target engagement by optimizing the delivery of the natural product through examination of different doses or formulations. In addition, applications can be designed to combine the natural product with another treatment approach that is known to impact the same target engagement measure; or study the impact of the natural product in a population that is more responsive,
