项目摘要

ABSTRACT Nontraumatic (aneurysmal) subarachnoid hemorrhage (aSAH) is one of the most dangerous forms of stroke, with almost half of victims dying within the first month after diagnosis, and a half of the survivors becoming severely disabled and incapable of living independently. This proposal is focused on addressing a common pathophysiological mechanism of neurocognitive outcomes of aSAH and other acute and chronic brain injuries – dysregulated overproduction of proinflammatory cytokines in the brain. Despite advances in our understanding of molecular neuroinflammatory mechanisms underlying adverse neuronal sequelae of acute and chronic brain injuries, approved therapeutics that target this pathological process are lacking. ImmunoChem Therapeutics (ICT) proposes to advance MW189, a novel small molecule anti-inflammatory experimental drug which has already successfully completed phase 1a and phase 1b clinical trials, as a candidate for a disease-modifying therapy for aSAH. MW189 is a selective suppressor of injury- and disease- induced proinflammatory cytokine overproduction associated with destructive glia inflammation/synaptic dysfunction cycles and their long-term neurotoxic effects. This proposed Fast-Track SBIR will deliver a phase 2a trial-ready drug and the corresponding regulatory documentation portfolio for a future pilot trial in aSAH. Specifically, we will: 1. Extend preclinical efficacy and pharmacodynamic data, and obtain the dosing and drug exposure information required to support a future phase 2a proof-of-concept clinical study in aSAH patients; 2. Produce and validate a GMP batch of the drug product from the existing cGMP drug substance (API) supply at a qualified Contract Manufacturing Organization (CMO); and 3. Prepare and submit an amendment to the open MW189 IND for a phase 2a clinical trial in aSAH patients. The Fast-Track structure will allow us to immediately move from proof of feasibility to SBIR Phase II activities that flow seamlessly from preparation of the Phase 2 trial-ready drug product to essential regulatory milestones for a future first-in-patient aSAH trial. Successful execution of the proposed project will position MW189 for immediate entry into a pilot proof-of-concept phase 2 trial in aSAH patients that will include pharmacokinetics and a pharmacodynamic arm. The success in that trial will, in turn, make MW189 a first-in-class drug candidate with a potential to become a novel therapeutic approach to SAH and other acute and chronic neurological disorders that involve dysregulated neuroinflammation as a driver of disease progression.

抽象的非创伤性（动脉瘤性）蛛网膜下腔出血（aSAH）是最危险的中风形式之一，几乎一半的受害者在诊断后的第一个月内死亡，一半的幸存者成为严重残疾，不能独立生活。该提案的重点是解决神经认知结果的常见病理生理机制 aSAH 和其他急性和慢性脑损伤 - 促炎细胞因子过度产生失调尽管我们对分子神经炎症机制的理解取得了进展。急性和慢性脑损伤的不良神经元后遗症，已批准针对此的治疗方法缺乏病理过程。免疫化学疗法 (ICT) 提议开发 MW189，一种新型小分子抗炎药物实验药物已成功完成1a期和1b期临床试验，作为 MW189 是一种针对 aSAH 的疾病缓解疗法的候选药物，是一种损伤和疾病的选择性抑制剂。诱导促炎细胞因子过量产生，与破坏性神经胶质炎症/突触相关拟议的快速通道 SBIR 将提供一个阶段的功能障碍周期及其长期神经毒性作用。 2a 可供试验的药物和相应的监管文件组合，用于未来 aSAH 的试点试验。具体来说，我们将： 1. 扩展临床前疗效和药效数据，获得给药剂量和药物暴露量支持未来针对 aSAH 患者的 2a 期概念验证临床研究所需的信息； 2. 从现有 cGMP 原料药 (API) 供应中生产并验证一批 GMP 药品在合格的合同制造组织 (CMO) 中；以及 3. 准备并提交针对 aSAH 患者的 2a 期临床试验的开放式 MW189 IND 修正案。快速通道结构将使我们能够立即从可行性证明转向 SBIR 第二阶段活动从准备第二阶段试验药物产品到重要监管里程碑的无缝流程未来首次住院 aSAH 试验的成功执行将使 MW189 处于有利位置。立即进入 aSAH 患者的概念验证阶段 2 试验，其中包括药代动力学该试验的成功将使 MW189 成为一流的候选药物。有潜力成为 SAH 和其他急慢性神经系统疾病的新型治疗方法涉及神经炎症失调作为疾病进展驱动因素的疾病。
