The EHDA supports the initial exploration of innovative, high-risk, high-gain, and potentially groundbreaking concepts in the TSC research field. The studies supported by this award mechanism are expected to generate preliminary data for future avenues of scientific investigation. The proposed research project should include a well-formulated, testable hypothesis based on a strong scientific rationale and study design. Applications should demonstrate the ability to achieve interpretable results in the absence of preliminary data supporting the hypothesis.The following are important aspects of the EHDA: Innovation: Innovative research may introduce a new paradigm, challenge existing paradigms, examine existing problems from new perspectives, or exhibit other highly creative qualities. Research that is an incremental advance upon published data is not considered innovative and is not consistent with the intent of the award mechanism. Although not all-inclusive, the following examples are ways in which the proposed research project may be innovative: Explores a novel idea and/or research question in TSC research and/or patient care. Uses or develops novel methods or technologies to address a question in TSC research and/or patient care. Applies or adapts existing methods or technologies for novel TSC research or clinical purposes that differ fundamentally from those originally intended.

This Notice informs that NIA intends to publish a Notice of Funding Opportunity (NOFO) inviting applications from mid-career investigators for mentored career enhancement awards focused on cross-disciplinary training to broaden and strengthen the investigator's capability to lead future comparative studies of the factors contributing to differences in life spans between human and nonhuman primate species. The NOFO is intended to provide support for experienced investigators with expertise in human and/or nonhuman primate (NHP) studies to do the following: 1) Augment or redirect their research program by acquiring expertise in other fields related to comparative primate research and aging 2) Develop collaborations with research fields with which they do not commonly interact This Notice is being provided to allow potential applicants sufficient time to identify potential mentors and prepare well-developed career enhancement plans. The NOFO is expected to be published in June 2024 with an anticipated application due date in November 2024. These are estimated time frames, and they may change. The NOFO is expected to utilize the K18 Career Enhancement Award activity code. It is expected that the NOFO will not allow clinical trials. Additional details of the planned NOFO are provided below.

Through this Notice of Funding Opportunity (NOFO), the National Cancer Institute (NCI) solicits applications for identification of small molecules that function to elucidate the biology of disease as chemical probes or function as agonists or antagonists of disease target(s) for therapy or immunotherapy. The NOFO is intended to support discovery research for the identification of validated hits relevant to health-related outcomes of participating NIH Institutes. Stages of discovery research covered by this NOFO include: 1) assay development for specific biological targets and disease mechanisms relevant to the mission of participating NIH Institutes with the intent to screen for small molecule compounds that show potential as probes for use in advancing knowledge about the known targets, identifying new targets, or as pre-therapeutic leads; 2) screen implementation high throughput target-focused approaches or moderate throughput phenotypic- and fragment-based approaches to identify initial screening hits; 3) hit validation, including implementation of secondary assays that are orthogonal to the primary assay, advanced cheminformatics analysis and initial medicinal chemistry inspection to prioritize the hit set, and follow-up assays to characterize mode and mechanism of action of the validated hits; 4) hit-to-lead optimization, including SAR to optimize target engagement, selectivity and to minimize chemical liabilities, ADME, PK and PD studies, and, if appropriate, in vivo modeling to test efficacy or biological effects.
