MDI治疗公司是一家开发新型小分子抑制剂的早期制药公司 纤溶酶原激活物抑制物-1(PAI-1)(基因：SERPINE1)用于治疗纤维增生性疾病。 纤维化的定义是细胞外基质(ECM)的成分过度积累，如 胶原和纤维连接蛋白，在发炎或受损的组织内和周围，可能导致永久性疤痕， 器官功能障碍，最终导致死亡。发达国家近45%的死亡被归因于一些 慢性纤维增生性疾病的类型。在急性和慢性纤维性肺病患者中， PAI-1的诱导。PAI-1最好的理解是它通过抑制纤维蛋白溶解和伤口愈合来调节纤溶和伤口愈合 组织型(TPA)和尿激酶型(UPA)纤溶酶原激活物，将酶原纤溶酶原转化为 活性酶纤溶酶。PAI-1作为伤口愈合的主要调节因子，包括在肺中的作用是 与其在纤维化中的关键调节作用一致。伤口愈合是受伤后的自然修复过程， 由包括止血、炎症、增殖和基质合成在内的重叠阶段组成，最后 决议。破坏这一有序的过程可能会导致伤口愈合受损，导致持续性 炎症和/或基质合成，最终导致纤维化综合征。PAI-1作为创伤的主要调节因子 愈合已被证明影响伤口愈合的所有阶段，并因此在肺损伤中起因果作用。 纤维化。MDI Treateutics已经开发出一种高效的、口服活性的PAI-1小分子抑制剂， MDI-2517，在多种肺纤维化模型中证明了有效性。这里提出的研究将 为申请研究新药(IND)所需的这种新疗法提供关键的IND使能数据 第一类PAI-1抑制剂(MDI-1)在进行人类第一阶段临床研究之前的应用 2517)用于治疗肺纤维化。具体的里程碑包括完成关键的GLP安全 提交研究新药所需的药理学、药代动力学和毒理学研究 (IND)MDI-2517申请。这些里程碑的成功完成将大大推进这一进程 通过提供开始人类第一阶段临床试验所需的数据，实现商业化。

MDI Therapeutics is an early-stage pharmaceutical company developing a new class of small molecule inhibitors of plasminogen activator inhibitor-type 1 (PAI-1) (gene: SerpinE1) for the treatment of fibroproliferative diseases. Fibrosis is defined by the excessive accumulation of components of the extracellular matrix (ECM), such as collagen and fibronectin, in and around inflamed or damaged tissue, which can lead to permanent scarring, organ malfunction and, ultimately, death. Nearly 45% of all deaths in the developed world are attributed to some type of chronic fibroproliferative disease. In patients with acute and chronic fibrotic lung disease there is a marked induction of PAI-1. PAI-1 is best understood for its role regulating fibrinolysis and wound healing by inhibiting the tissue-type (tPA) and urokinase-type (uPA) plasminogen activators, which convert the zymogen plasminogen to the active enzyme plasmin. The role of PAI-1 as a primary regulator of wound healing, including in the lung, is consistent with its critical regulatory role in fibrosis. Wound healing is a natural repair process after injury that consists of overlapping stages, including hemostasis, inflammation, proliferation and matrix synthesis, and finally resolution. Disruption of this ordered process can result in impaired wound healing, leading to persistent inflammation and/or matrix synthesis and ultimately to a fibrotic syndrome. PAI-1, as a primary regulator of wound healing has been shown to impact all stages of wound healing, and accordingly to play a causal role in pulmonary fibrogenesis. MDI Therapeutics has developed a highly effective, orally active, small molecule inhibitor of PAI-1, MDI-2517, with demonstrated efficacy in multiple models of pulmonary fibrosis. The studies proposes here will provide critical IND-enabling data for this novel therapeutic necessary for filing an Investigational New Drug (IND) application prior to conducting first-in-human Phase 1 clinical studies of the first-in-class PAI-1 inhibitor (MDI- 2517) for the treatment of pulmonary fibrosis. Specific milestones include completion of key GLP safety pharmacology, pharmacokinetics and toxicology studies required for submission of an Investigational New Drug (IND) application for MDI-2517. The successful completion of these milestones will significantly advance this program toward commercialization by providing data necessary for the start of human Phase 1 clinical trials.
