项目摘要

Project Summary/Abstract Sudden Unexpected Death in Epilepsy (SUDEP) is the leading cause of death in epilepsy children and otherwise healthy adult epilepsy patients, with a cumulative lifetime risk of ~8%. About 70% of SUDEP occurs during sleep, and nearly 90% are found in the prone (face-down) position. SUDEP can likely be prevented by the simple intervention of repositioning and stimulating the patient after a convulsive seizure. Such intervention must be performed quickly and autonomously within a critical 3-minute window after a convulsion. Soterya, Inc., founded with the mission to develop technologies to decrease the risk of SUDEP, addresses this critical unmet medical need with an innovative smart mattress, the KORUS. Soterya has demonstrated feasibility by developing a functional alpha prototype consisting of an array of expandable cells and a shapeable surface that safely and rapidly repositions human subjects. There are currently no products that detects the prone position and physically repositions a patient into a recovery (sideways) position. The goal of this Phase I SBIR is to develop and validate two key technologies required to successfully develop a fully functional autonomous prototype: 1) advanced expandable cell with the size, weight, safety features, and noise management suitable for a human clinical trial, while maintaining our benchmark of generating enough lift at a required velocity with a 1000 lb/cell capacity; 2) embedded sensor system for rapid detection of body position change, and detection of the prone position. Soterya will optimize sensor manufacturing capabilities and software tools for body positioning visualization and data processing, and develop software for integrating these tools into a single sensory network system. Human feasibility testing will be performed through our academic partners at the epilepsy and sleep medicine service of the Brigham and Women’s Hospital. A total of 10 normative control subjects will be recruited to test the device efficacy in repositioning, awake testing to assess detection of body position changes, and overnight testing for detecting spontaneous body position changes during sleep. Milestones for this study will be 1) safely repositioning subjects from a prone to a recovery position within 30 seconds; 2) detecting body position changes into a prone position with 95% accuracy. The completion of this project will position Soterya for the development of a fully functional prototype. A subsequent Phase 2 study will pair the KORUS with a commercial seizure detection device for a clinical trial in the hospital epilepsy monitoring unit, with the ultimate goal of developing a fully embedded seizure detection and management system. The development of KORUS as a medical device for the night-time management of convulsive seizures will achieve a 50-75% risk reduction of night-time SUDEP.

项目概要/摘要癫痫猝死（SUDEP）是癫痫儿童和癫痫患者死亡的主要原因其他方面健康的成年癫痫患者，一生中发生 SUDEP 的累积风险约为 8%。睡眠期间，近 90% 的人处于俯卧（面朝下）姿势，SUDEP 可能可以通过以下方式预防。惊厥性癫痫发作后重新定位和刺激患者的简单干预措施。必须在抽搐后关键的 3 分钟时间内快速、自主地进行。 Inc. 的成立宗旨是开发降低 SUDEP 风险的技术，解决这一关键问题 Soterya 已通过创新智能床垫证明了其未满足的医疗需求。开发由一系列可扩展单元和可塑形表面组成的功能性阿尔法原型可以安全、快速地重新定位人类受试者，目前还没有产品可以检测俯卧状态。将患者重新定位到恢复（侧向）位置这是第一阶段 SBIR 的目标。是开发和验证成功开发功能齐全的自主驾驶所需的两项关键技术原型：1) 先进的可扩展电池，具有合适的尺寸、重量、安全特性和噪音管理对于人体临床试验，同时保持我们以所需速度产生足够升力的基准 1000 lb/cell容量；2）嵌入式传感器系统，用于快速检测身体位置变化，并检测 Soterya 将优化身体传感器制造能力和软件工具。定位可视化和数据处理，并开发将这些工具集成到一个单一的软件中感官网络系统。人类可行性测试将通过我们的学术合作伙伴进行。布莱根妇女医院的癫痫和睡眠医学服务共10项规范对照。将招募受试者来测试设备在重新定位、清醒测试中的功效，以评估身体检测位置变化，以及夜间测试以检测睡眠期间自发的身体位置变化。这项研究的里程碑是 1) 在 30 天内将受试者从俯卧位置安全地重新定位到恢复位置秒；2) 检测身体位置变为俯卧位，准确率达到 95%。该项目将让 Soterya 开发一个功能齐全的原型，并进行后续的第二阶段研究。将 KORUS 与商用癫痫检测设备配对，用于医院癫痫症临床试验监测单元，最终目标是开发完全嵌入式癫痫检测和管理开发 KORUS 作为夜间治疗惊厥的医疗设备。夜间 SUDEP 的癫痫发作风险可降低 50-75%。
