项目摘要

Pulmotect, Inc. was founded in 2007 to translate discoveries that induce innate immune resistance in the lung into therapeutics that will provide protection from inhaled pathogens. Our technology platform is a direct result of basic research by our founders on the mechanisms of microbial resistance in the lung epithelium. We have developed an inhaled therapeutic, PUL-042, that provides immediate protection against a broad spectrum of respiratory pathogens. PUL-042 is a clinical stage, specific combination of two well-characterized synthetic molecules, a lipopeptide (Pam2CSK4) and an oligodeoxynucleotide (ODN M362) that act as agonists of the Toll-like Receptors TLR2/6 and TLR9, respectively. This unique, proprietary combination of molecules synergizes to rapidly and powerfully stimulate the body’s natural defenses. The response is localized and specific to the site of administration. In mice, treatment before and after exposure with aerosolized PUL-042 results in increased survival rates to pathogens including multiple Gram+ and Gram– bacteria (three of which are Class A bioterror agents), the fungus Aspergillus fumigatus, and the Sendai and influenza viruses. In each case, increased survival is associated with a reduction of lung pathogen burden, not simply increased tolerance to the pathogen by the host, which indicates a resistance mechanism of action. Pulmotect's long-term strategy is to leverage its technology across a wide array of important threats from inhaled pathogens by limiting the pathogen burden and transmission of disease. The range of applications for PUL-042 currently in development includes use in immunosuppressed patients, pandemic influenza, asthma exacerbations associated with viral infections and manmade bioterror threats as well as naturally emerging viruses. While this broad spectrum technology is not envisioned to replace traditional vaccine approaches, its value and differentiation reside in the ability to confer immediate host-based protection that is not limited by the identity of the pathogen. The potential indications that lie outside the scope of this proposal are synergistic, building on experimental methods that we established since our earliest research in this field. The scientific basis of boosting the innate immune system in the lungs is rapidly expanding as we better understand the underlying mechanism of action. The primary goal of this proposal is to complete a Phase II clinical trial in immunosuppressed cancer patients. This will be a multi-center randomized double-blind trial that will compare PUL-042 against placebo on the overall incidence and severity of pneumonia, specifically on those who have been screened to have a parainfluenza infection prior to enrollment. The three objectives of the trial are described below. • Primary objective: to determine the safety and tolerability of PUL-042 inhalation solution in patients with documented parainfluenza infection. • Secondary objective: to determine the efficacy of PUL-042 inhalation solution to prevent the progression of documented parainfluenza infection to clinically documented lower respiratory tract infection. • Exploratory objectives: 1) evaluate the effect of PUL-042 on parainfluenza viral titers and neutralizing antibodies; 2) evaluate the effect of PUL-042 over time on the microbiome and virome in nasal washes in the study population; and 3) determine whether PUL-042 induces neutralizing antibodies against PUL-042 components. The successful achievement of these objectives will demonstrate proof-of-concept in man and further validate the technology for market use. With secured matching funds already in place, this NIH proposal is designed to help move the project to the end goal, rather than provide the initial seed funds to start the process. The Company would be well positioned to advance existing collaborations, partnerships and discussions with leading large pharma and biotechnology organizations, accelerating the path to the market to address the serious unmet needs that many patients are currently facing.
Pulmotect公司成立于2007年,致力于转化在肺部诱导先天免疫抵抗的发现。 转化为治疗药物,以防止吸入病原体。我们的技术平台是一个直接的结果 我们的创始人对肺上皮中微生物耐药性机制的基础研究。我们有 开发了一种吸入治疗剂,PUL-042,可立即保护患者免受广泛的 呼吸道病原体PUL-042是临床阶段的两种充分表征的合成药物的特异性组合。 分子、脂肽(Pam 2CSK 4)和寡脱氧核苷酸(ODN M362),其作为该受体的激动剂起作用。 Toll样受体TLR 2/6和TLR 9。这种独特的专有分子组合 协同作用,迅速而有力地刺激身体的自然防御。反应是局部的, 特定于给药部位。在小鼠中,暴露于雾化PUL-042之前和之后的治疗 导致对包括多种革兰氏+和革兰氏-细菌(其中三种 是A类生物恐怖剂)、真菌烟曲霉、仙台病毒和流感病毒。在每个 在这种情况下,生存率的增加与肺病原体负荷的减少有关,而不仅仅是增加 宿主对病原体的耐受性,这表明了一种抗性作用机制。 Pulmotect的长期战略是利用其技术应对各种重要威胁, 通过限制病原体负担和疾病传播来减少吸入的病原体。的应用范围 目前正在开发的PUL-042包括用于免疫抑制患者、大流行性流感、哮喘 与病毒感染和人为生物恐怖威胁以及自然出现的 病毒虽然这种广谱技术并不能取代传统的疫苗方法,但其 其价值和独特性在于能够立即提供基于主机的保护,而不受 病原体的身份本提案范围之外的潜在迹象是协同作用, 建立在我们在这一领域最早的研究中建立的实验方法之上。科学 增强肺部先天免疫系统的基础正在迅速扩大,因为我们更好地了解了 潜在的作用机制。 该提案的主要目标是在免疫抑制的癌症患者中完成II期临床试验。 这将是一项多中心随机双盲试验,将PUL-042与安慰剂进行比较, 肺炎的总体发病率和严重程度,特别是在那些已被筛选为 入组前感染副流感病毒。试验的三个目的如下所述。 ·主要目的:确定PUL-042吸入溶液在患有哮喘的患者中的安全性和耐受性。 记录的副流感病毒感染。 ·次要目的:确定PUL-042吸入溶液预防哮喘进展的功效。 记录的副流感病毒感染至临床记录的下呼吸道感染。 ·探索性目的:1)评价PUL-042对副流感病毒滴度和中和作用的影响 2)评估PUL-042随时间对鼻洗液中微生物组和病毒组的影响, 研究群体;和3)确定PUL-042是否诱导针对PUL-042的中和抗体 件. 这些目标的成功实现将证明概念在人身上的证明,并进一步验证 技术用于市场。由于有担保的配套资金已经到位,NIH的这一提案旨在 帮助项目实现最终目标,而不是提供启动过程的初始种子资金。的 公司将处于有利地位,以推进现有的合作,伙伴关系和讨论, 领先的大型制药和生物技术组织,加快市场的道路,以解决 这是许多患者目前面临的严重需求。
