项目摘要
Abstract
Excessive alcohol use remains a leading preventable cause of death and disability in the United States.
According to the Centers for Disease Control and Prevention (CDC), an average of 95,158 alcohol-attributable
deaths (261 deaths per day) is reported only in the United States, with associated annual costs of $249 billion.
The goal of this project is to develop a wearable integrated device capable of continuously measuring, recording,
and storing ISF alcohol levels in real-time without the need for external calibrations. The National Institute on
Alcohol Abuse and Alcoholism (NIAAA) seeks a wearable alcohol monitoring device that can continuously
measure real-time alcohol levels in the blood or interstitial fluid (ISF), and this proposal is highly aligned with the
NIAAA’s mission. An accurate wearable alcohol sensor will serve useful purposes in different settings, including
research programs, clinics, forensic applications, and consumer use to promote responsible alcohol
consumption. The available transdermal alcohol monitoring devices, relying on alcohol detection in sweat or
sweat vapor, face significant problems such as long lag times (up to several hours) and tend to be cumbersome.
In this context, ActioX, LLC has developed a non-obtrusive wearable sensor platform to enable pain-free analysis
few hundred microns under the skin, directly in the ISF. The novel sensing technology relies on a biocompatible
array of microneedles, optimized for painless skin penetration, and thus to provide continuous access to
constantly revitalizing ISF. This fully integrated wirelessly operated device is composed of two components of a
reusable electronics and a disposable microneedle array, along with a successful demonstration of a custom-
designed app for data capture and visualization. Our preliminary data using the prototype device showed
successful real-time tracking of ISF alcohol in response to alcohol drinking episodes in multiple human subjects,
with the results well correlated to those from a breathalyzer. This SBIR Fast-Track project will leverage this
innovative technology to develop a discreet, real-time, continuous, and calibration-free continuous alcohol
monitoring device toward prolonged on-body operations to enable more comprehensive and accurate clinical
studies and allow efficient control and management of alcohol-related problems, including alcohol use disorder.
Phase I constitutes in-vitro feasibility studies to find the best chemical modification strategy with optimal
sensitivity, selectivity, reproducibility, and extended 3-days stability. We aim in Phase II to execute a series of
clinical studies to develop a prospective calibration algorithm that can convert, in real time, the raw
electrochemical sensor signals to BAC. The data gathered through this work will support FDA clearance, and
subsequently, the commercialization of our real-time, continuous alcohol monitoring wearable system as a
reliable and accurate device ready to be used by end users, including hospitals, drug rehabilitation centers, drug
testing laboratories, government departments, and others.
摘要
在美国,过度饮酒仍然是导致死亡和残疾的主要可预防原因。
根据疾病控制和预防中心(CDC)的数据,平均有95,158名酒精中毒者
死亡(每天261人死亡)仅在美国报告,相关的年度成本为2490亿美元。
该项目的目标是开发一种可穿戴的集成设备,能够连续测量,记录,
并实时存储ISF酒精水平,无需外部校准。国家研究所
酒精滥用和酒精中毒(NIAAA)寻求一种可穿戴的酒精监测设备,
测量血液或组织间液(ISF)中的实时酒精水平,这一提议与
NIAAA的使命。准确的可穿戴酒精传感器将在不同的环境中发挥作用,包括
研究计划,诊所,法医应用和消费者使用,以促进负责任的酒精
消费现有的透皮酒精监测装置依赖于汗液或尿液中的酒精检测,
汗蒸气面临着诸如长滞后时间(长达几个小时)的重大问题,并且往往是麻烦的。
在这种背景下,ActioX,LLC开发了一种非侵入式可穿戴传感器平台,以实现无痛分析
几百微米的皮肤下,直接在ISF。新的传感技术依赖于生物相容性
微针阵列,针对无痛皮肤穿透进行了优化,从而提供持续的
不断振兴ISF。这种完全集成的无线操作设备由两个组件组成,
可重复使用的电子器件和一次性微针阵列,沿着定制的成功演示,
专为数据捕获和可视化而设计的应用程序。我们使用原型设备的初步数据显示,
在多个人类受试者中成功实时跟踪响应于饮酒事件的ISF酒精,
其结果与来自呼吸测醉器的结果很好地相关。SBIR快速通道项目将利用这一点
创新技术,开发出一种谨慎、实时、连续和免校准的连续酒精
监测设备,以实现更全面和准确的临床
这些研究有助于有效控制和管理与酒精有关的问题,包括酒精使用障碍。
第一阶段包括体外可行性研究,以找到最佳的化学修饰策略,
灵敏度、选择性、再现性和延长的3天稳定性。我们的目标是在第二阶段执行一系列
临床研究,以开发一种前瞻性校准算法,该算法可以真实的时间,
电化学传感器向BAC发出信号。通过这项工作收集的数据将支持FDA的批准,
随后,我们的实时,连续酒精监测可穿戴系统的商业化,
可靠和准确的设备,可供最终用户使用,包括医院、戒毒中心、药物治疗中心、
检测实验室、政府部门等。
