项目摘要

PROJECT SUMMARY ORC-13661 is a new chemical entity being developed to prevent hearing loss in patients exposed to aminoglycoside antibiotics (AGs). AGs are an important class of broad spectrum antibiotics especially effective against gram-negative bacteria and Mycobacteria. Unfortunately, as many as 20% of patients administered parenteral AGs for over 5 days suffer permanent, measurable hearing loss, as do upwards of 60% of patients on long term therapy. Largely because of the ototoxic side effects, AGs are currently administered only for life threatening situations or where they are the only effective treatment. At this time there are no FDA approved drugs that have been shown to prevent any form of sensorineural hearing loss. Preventing AG-induced hearing loss would be of enormous benefit patients currently being treated with AGs. It would also allow this inexpensive and effective but underused class of antibiotics to be used more routinely. Oral ORC-13661was developed from a small molecule screen aimed finding a way to mitigate AG-induced hair cell toxicity. It is robustly effective at preventing hearing loss in rats treated with prolonged high dose AGs. ORC-13661 has completed nonclinical evaluation and Phase 1 testing in normal healthy volunteers. Pulmonary and disseminated non-tuberculous Mycobacteria (NTM) infections are chronic infectious diseases that develop progressively over time, and require prolonged parenteral AG therapy to achieve control or a cure. Current guidelines recommend parenteral aminoglycoside (AG) therapy, usually a 90 day course of amikacin, for patients with severe manifestations of the disease, particularly bronchiectasis. We propose a randomized, double-blind, placebo-controlled, multicenter, phase 2 study of ORC-13661 administered orally in conjunction with intravenously administered amikacin to patients with severe NTM infections. The goal of this to evaluate the efficacy of ORC-13661 for mitigation or prevention of ototoxicity. Primary and secondary endpoints are changes in between baseline measures if hearing thresholds and hearing in noise taken prior to drug treatment and after treatment is discontinued in groups of patients treated with amikacin alone or with amikacin plus ORC-13661. Additional evaluations will changes in patient perceived hearing and balance health and the safety and tolerability of ORC-13661 in patients with NTM as assessed by AEs, clinical laboratory findings, vital signs, and electrocardiogram (ECG).
项目摘要 ORC-13661是一种正在开发的新化学实体,用于预防暴露于 氨基糖苷类抗生素(AG)。AG是一类重要的广谱抗生素, 对革兰氏阴性菌和分枝杆菌有效。不幸的是,多达20%的患者 给药超过5天的胃肠外AG遭受永久的、可测量的听力损失, 60%的患者接受长期治疗。主要由于耳毒性副作用,AG目前 仅在危及生命的情况下或在它们是唯一有效治疗的情况下施用。此时 没有FDA批准的药物已被证明可以预防任何形式的感音神经性听力损失。 预防AG引起的听力损失将使目前接受AG治疗的患者受益匪浅。它 也将使这种廉价有效但未被充分利用的抗生素类更常规地使用。 口服ORC-13661是从一种旨在寻找减轻AG诱导毛发的方法的小分子筛选中开发出来的 细胞毒性它在预防长期高剂量AG治疗的大鼠的听力损失方面是稳健有效的。 ORC-13661已在正常健康志愿者中完成非临床评价和I期试验。 肺部和播散性非结核分枝杆菌(NTM)感染是慢性传染病 其随时间逐渐发展,并且需要延长的胃肠外AG治疗以实现控制或治愈。 目前的指南推荐肠外氨基糖苷类(AG)治疗,通常是90天的阿米卡星疗程, 对于有严重疾病表现的患者,特别是支气管扩张症。 我们提出了一项ORC-13661的随机、双盲、安慰剂对照、多中心、II期研究 口服联合静脉注射阿米卡星治疗重度NTM患者 感染.本研究旨在评价ORC-13661缓解或预防耳毒性的疗效。 主要和次要终点是基线测量值之间的变化,如果听力阈值和 在接受治疗的患者组中,在药物治疗前和治疗停止后采集噪声中的听力 与阿米卡星单独或与阿米卡星加ORC-13661联合。额外的评价将改变患者的感知 听力和平衡健康以及ORC-13661在NTM患者中的安全性和耐受性, AE、临床实验室检查结果、生命体征和心电图(ECG)。
