The broader impact of this Small Business Innovation Research (SBIR) Phase I project is to alleviate the suffering caused by hyper-inflammation. Hyper-inflammation is a mis-regulation of the immune system often brought on by viral pneumonia. It can have severe life-threatening complications, including acute respiratory distress syndrome (ARDS) and changes in blood clotting; hyper-inflammation has been seen in COVID-19 patients. Secondary conditions caused by hyper-inflammation can also have severe long-term consequences to patient health. This project will develop therapeutics that quiet the systemic mis-regulation of the immune system and reduce patient mortality. The proposed project will advance a treatment for hyper-inflammation, such as that induced by COVID-19. It arises from multiple stimuli and results in life-threatening mis-regulation of the immune system. With a novel molecular target, a new class of anti-fibrotic compounds have the potential to reduce cytokine levels and pro-coagulation factors, acting broadly to address the heterogeneity of inflammation responses. As information becomes available regarding the cytokine storm induced by COVID-19, relevant biomarkers have been proposed. To demonstrate robust actions on inflammation this project will evaluate the effects of the therapeutic on 1) pro-inflammatory cytokine release, 2) activation of the innate immune system, and 3) systemic concentrations of cytokines and pro-coagulation factors after initiation of inflammation. Biomarkers will be established to track the efficacy of the therapeutic at early and late stages of inflammation, providing a strong rationale for testing the efficacy of this class of compounds in animal models of inflammation. Importantly, with the successful completion of this project, this class of therapeutics will have demonstrated potential to treat hyper-inflammation, coupled with a demonstrated ability to prevent pulmonary fibrosis, a potentially fatal complication.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

这个小企业创新研究（SBIR）第一阶段项目的更广泛影响是减轻炎症引起的痛苦。 过度炎症是一种免疫系统的错误调节，通常由病毒性肺炎引起。它可能会出现严重的危及生命的并发症，包括急性呼吸窘迫综合征（ARDS）和凝血变化;在COVID-19患者中发现了过度炎症。由过度炎症引起的继发性疾病也可能对患者健康产生严重的长期后果。该项目将开发治疗方法，使免疫系统的系统性错误调节安静下来，并降低患者死亡率。拟议的项目将推进对过度炎症的治疗，例如COVID-19引起的炎症。它由多种刺激引起，并导致危及生命的免疫系统失调。具有新型分子靶点的新型抗纤维化化合物具有降低细胞因子水平和促凝血因子的潜力，广泛用于解决炎症反应的异质性。随着关于COVID-19诱导的细胞因子风暴的信息变得可用，已经提出了相关的生物标志物。 为了证明对炎症的强大作用，该项目将评估治疗剂对1）促炎细胞因子释放，2）先天免疫系统激活和3）炎症开始后细胞因子和促凝血因子的全身浓度的影响。将建立生物标志物来跟踪治疗剂在炎症早期和晚期阶段的疗效，为在炎症动物模型中测试这类化合物的疗效提供强有力的依据。重要的是，随着该项目的成功完成，这类疗法将被证明具有治疗高度炎症的潜力，并被证明具有预防肺纤维化（一种潜在的致命并发症）的能力。该奖项反映了NSF的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。
