中文摘要
摘要:
中国的艾滋病毒/艾滋病仍然是一种令人敬畏的全球全球流行病,约有3700万人感染了艾滋病(包括8月份的约110万人)。
2017年上半年,美国(联合国艾滋病规划署、美国疾病控制与预防中心)报告了约100万例与艾滋病相关的死亡病例。
联合抗逆转录病毒药物治疗(CART)、副作用和耐药性仍然是治疗的严重障碍。
实现最优的医疗、医疗和不良的医疗依从性是治疗失败的一个关键因素。因此,这一点是持续存在的。
对耐受性良好的艾滋病病毒抑制剂的需求,需要新的有效作用机制,以及更强大的耐药性障碍。
艾滋病专家对开发长效药物治疗的潜在潜力尤其感兴趣,以将副作用降至最低。
通过改善药物合规性来增强疗效,预防和延缓耐药性的发生。Navigen已经确定这是一部全新的小说。
具有蛋白酶抗性的D-肽是HIV病毒进入的抑制剂,具有这些理想的药物特性,并且已经取得了进展。
通过临床前药物的开发,CCPT31解决了当前Cart技术的许多局限性,并已被证明是可行的。
对于非人类非人类灵长类动物(NHP)的这两种适应症,都应该很好地耐受,并对其进行高效治疗,这使其成为一种非常理想的治疗方法。
此外,CPT31的S的PK使得他很容易接受每月一次的治疗,也许还会有一些。
季度配药计划(有仓库配方)。在这次的拨款申请中,我们将继续与约翰斯和霍普金斯大学合作。
大学将继续进行Ia/Ib阶段的研究,包括安全性、耐受性、药代动力学、临床和药效学研究。
CPT31.这项研究将包括以下三个阶段:(1)在健康志愿者中进行单次剂量递增试验(SAD),(2)进行多次试验。
3)在健康志愿者中,艾滋病毒阳性患者中的狂犬病患者被归类为第一组。
美国食品和药物管理局为该行业提供了指导意见。这项研究将使纳维根公司能够更好地确定CPT31是否已经生效。
这些特点表明,需要继续进行临床药物研究,并需要进一步的药物投资。
英文摘要
SUMMARY
HIV/AIDS remains a formidable global epidemic, with ~37 million people infected (including ~1.1 million in
the US) and about one million AIDS-related deaths in 2017 (UNAIDS, CDC). Despite the efficacy of modern
combination anti-retroviral therapy (cART), side effects and drug resistance remain serious obstacles to
achieving optimal care, and poor adherence is a key factor in treatment failure. Thus, there is continued
demand for well-tolerated HIV inhibitors with novel mechanisms of action and stronger barriers to resistance.
HIV specialists are especially enthusiastic about the potential of long-acting therapies to minimize side effects,
enhance efficacy, and delay resistance through improved compliance. Navigen has identified a novel,
protease-resistant D-peptide HIV entry inhibitor, CPT31, with these desired characteristics and has advanced it
through preclinical development. CPT31 addresses many of the limitations of current cART and has proven to
be well tolerated and highly efficacious for both indications in non-human primates (NHPs), making it an ideal
candidate for both therapy and PrEP. Additionally, CPT31’s PK makes it amenable to monthly and perhaps
quarterly dosing (with depot formulation). In this grant application, we will partner with Johns Hopkins
University to conduct a Phase Ia/Ib safety, tolerability, pharmacokinetics, and pharmacodynamics study of
CPT31. The study will include three stages: 1) single ascending dose (SAD) in healthy volunteers, 2) multiple
ascending dose (MAD) in healthy volunteers, and 3) MAD in HIV positive patients classified as Group 1 under
the FDA guidance for industry. This study will enable Navigen to determine whether CPT31 has the
characteristics that warrant continued clinical studies and further investment.
