Funding Opportunity RFA-DA-26-003 from the NIH Guide for Grants and Contracts. 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

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,

The purpose of this notice of funding opportunity (NOFO) is to support the investigation of HIV-1 Envelope (Env) cell surface expression, the structural mechanism of biologic-mediated cell killing, and the development of novel approaches to enhance the recognition and elimination of Env-expressing, HIV-1 infected cells. These studies are expected to inform the development of immunotherapies and targeted vaccines for HIV-1 prevention and cure.

Funding Opportunity PAR-25-266 from the NIH Guide for Grants and Contracts. This FOA encourages research relevant to the development of novel screening approaches and/or therapeutic interventions for potentially fatal or disabling conditions that have been identified through newborn screening, as well as for "high priority" genetic conditions where screening may be possible in the near future.Having an accurate screening test, as well as demonstrating the benefits of early intervention or treatment, are important criteria for including a condition on a newborn screening panel. This FOA defines a "high priority" condition as one where screening is not currently recommended, but infants with the condition would significantly benefit from early identification and treatment.

Funding Opportunity PAR-25-285 from the NIH Guide for Grants and Contracts. This R61/R33 concept complements NIMHs suite of clinical trial NOFOs by supporting feasibility and infrastructure development (R61) followed by well-powered clinical trials (R33) to test the effectiveness of system interventions and strategies for improving the organization, delivery, coordination, and clinical and functional outcomes of mental health services. System interventions - which may span, for example, structural, policy, organizational, and interpersonal domains - attend to issues about the access, equity, engagement/utilization, value (cost/financing), management, or quality and safety of mental health services, with the goal of improved care processes and clinical and functional outcomes. Accordingly, the focus of system interventions may include a variety of care settings, such as health systems and organizations, mental health and community clinics, schools, and child welfare or juvenile justice systems

Funding Opportunity PAR-25-184 from the NIH Guide for Grants and Contracts. NIMH requires an experimental therapeutics approach for the development and testing of therapeutic interventions, in which studies both evaluate the clinical effect of an intervention and generate information about the mechanisms underlying a disorder or an intervention response. As part of NIMHs Clinical Trial Pipeline, this NOFO encourages early stage testing of pharmacologic interventions with novel mechanisms of actions or device-based interventions. More specifically, this NOFO is intended to support early stage testing of pharmacologic or device-based interventions using a protocol design where the presumed mechanism of action of the intervention is adequately tested, to provide meaningful information where target modulation yields a dose-dependent neurophysiological/clinical/behavioral effect.
