Part 2. Full Text Announcement Section I. Funding Opportunity Description current language reads: Examples activities R21 phase include, are limited to: Development assay(s) support succinct testing funnel, including example, assays measure specificity, potency, stability protease and/or metabolic enzymes, cellular uptake. combination assays be developed demonstrate relevant biological activity a single assay not provide adequate measurement overall potency due a complex mechanism action multiple activities a biologic. Development in vitro ex vivo potency/efficacy assay designed indicate specific ability an agent achieve desired biological effect, example: structural changes may impact product quality, stability, efficacy. Development assays evaluate cellular uptake, engagement, infection, aggregation, downstream functional measures vitro ex vivo, purity, specificity. Assays measure DNA, RNA, protein levels either endogenous genes delivered products, downstream vitro ex vivo functional read-outs, viral titer, viral particle load stability specificity. Development assays evaluate purity identity the therapeutic surface markers specific proteins, morphological measures, differentiation, purity, functional measures vitro ex vivo, stability, immunogenicity. Examples activities the R33 phase include, are limited to: Preparation screening select series therapeutic agents using example medicinal chemistry biological processes. Preparation therapeutic agent(s) confirmation structure, sequence biological characteristics Development selection cell lines/vectors produce bioactive agents acceptable potency stability, production, cellular uptake/engagement, secondary vitro functional assays. Assessment therapeutic agent’s properties using computational analysis early physicochemical measurements, polar surface area, solubility, cell permeability efflux. Assessment initial pharmacokinetic parameters such absorption, distribution, metabolism, excretion ADME). Assessment potential off target activities. Optimization therapeutic agent(s). Examples activities are appropriate this FOA include, are limited to: Studies designed establish proof concept a biological target covered PA-13-302). Development assays probes support basic understanding disease other basic research. Basic research supported PA-13-302, Research Project Grant Parent R01). High-throughput screening HTS), comprising screening large random chemical libraries activity against biological targets via use automation, miniaturized assays large-scale data analysis. HTS defined the number compounds tested the range 10,000100,000 per day. covered PAR-14-284 ). Assay development HTS covered PAR-13-364 ). Pharmacodynamics in vivo efficacy studies covered through companion PAR-15-071 ). Development devices, surgical procedures, diagnostics, rehabilitation strategies. Development risk, detection, diagnostic, prognostic, predictive, prevention biomarkers. Studies disease mechanism. Studies use therapeutic agents identify targets relevant a disease.
