ABSTRACT Long-term survival rates for children diagnosed with acute lymphoblastic leukemia (ALL) currently exceed 90%. However, prolonged ALL chemotherapy, which lasts two to three years on average, is associated with significant fatigue and sleep disturbances in both children and their caregivers. In fact, patients and caregivers often identify excess fatigue and sleep disturbances as the most distressing symptoms experienced during ALL treatment. In addition to adversely impacting quality of life during treatment, fatigue and sleep problems may alter mood, result in long-term cognitive dysfunction, and potentially compromise treatment efficacy. Despite unfavorable fatigue and sleep being a pervasive problem in children with ALL and their caregivers, effective intervention options are limited. Therefore, there is a significant unmet clinical need to identify evidence-based, minimally invasive strategies to intervene and restore circadian rhythmicity in pediatric patients with ALL and their caregivers. Building upon our previous success developing mobile applications to address cancer-related fatigue in adult oncology populations, this proposal seeks to adapt a pilot mobile application to track sleep and circadian rhythms in patients with ALL and their caregivers. While many existing resources provide information on the importance of sleep duration, few highlight the role of circadian rhythms and light exposure. In particular, while numerous commercial wearables exist that can track sleep, few if any give personalized recommendations for how light exposure and other behaviors can be used to improve sleep, especially in populations that are likely to have highly disrupted sleep. The proposed project will leverage consumer wearable technology to conduct sleep and circadian analysis for children with ALL for the purposes of prescribing lighting and behavioral recommendations to help improve sleep in these patients. Moreover, we propose to extend the analysis and the prescriptions beyond the patients themselves, to their caregivers, improving outcomes for the entire family. Specifically, this Phase I STTR proposes two aims: 1) we will design a mobile app for reducing cancer-related fatigue in pediatric patients with ALL and their caregivers using a patient-centered approach refined with feedback from patient-caregiver dyads, and 2) we will conduct a usability study in a population of 16 patient-caregiver dyads to assess the feasibility of an app-delivered light and behavior-based intervention in this population. The results of this Phase I application will provide the foundation necessary to conduct a Phase II trial to assess the efficacy of the new app to reduce fatigue and improve sleep quality and duration in a large population of pediatric ALL patients and their caregivers. Ultimately, we anticipate this line of research will lead to the identification of a feasible, minimally invasive, effective intervention to address fatigue and sleep issues in this vulnerable population, leading to improvements in quality of life and outcomes.

抽象的 被诊断患有急性淋巴细胞白血病（ALL）的儿童的长期生存率目前超过 90%。然而，平均持续两到三年的长期 ALL 化疗与 儿童及其照顾者均出现明显的疲劳和睡眠障碍。事实上，患者和护理人员 经常将过度疲劳和睡眠障碍视为 ALL 期间经历的最令人痛苦的症状 治疗。除了在治疗期间对生活质量产生不利影响外，疲劳和睡眠问题还可能 改变情绪，导致长期认知功能障碍，并可能损害治疗效果。尽管 不利的疲劳和睡眠是 ALL 儿童及其护理人员普遍存在的问题，有效 干预选择是有限的。因此，临床需求尚未得到满足，需要确定基于证据的、 干预和恢复 ALL 儿童患者昼夜节律的微创策略 他们的照顾者。基于我们之前开发移动应用程序以解决癌症相关问题的成功 由于成人肿瘤人群的疲劳，该提案旨在采用试点移动应用程序来跟踪睡眠和 ALL 患者及其护理人员的昼夜节律。虽然许多现有资源提供了信息 关于睡眠持续时间的重要性，很少有人强调昼夜节律和光照的作用。尤其， 虽然存在许多可以跟踪睡眠的商业可穿戴设备，但很少有提供个性化的功能 关于如何利用光照和其他行为来改善睡眠的建议，尤其是在 睡眠可能受到严重干扰的人群。拟议的项目将利用消费者 可穿戴技术对患有 ALL 的儿童进行睡眠和昼夜节律分析，以便 制定照明和行为建议以帮助改善这些患者的睡眠。此外，我们 建议将分析和处方扩展到患者本身之外，扩展到他们的护理人员， 改善整个家庭的成果。具体来说，第一阶段 STTR 提出了两个目标：1）我们将设计 一款移动应用程序，用于减少 ALL 儿科患者及其护理人员与癌症相关的疲劳，使用 根据患者与护理人员二人组的反馈完善以患者为中心的方法，并且 2) 我们将开展 对 16 名患者-护理人员二人组进行可用性研究，以评估应用程序提供的光的可行性 以及针对这一人群的基于行为的干预。第一阶段申请的结果将提供 进行第二阶段试验以评估新应用程序减少疲劳和缓解疲劳的功效所必需的基础 改善大量儿科 ALL 患者及其护理人员的睡眠质量和持续时间。 最终，我们预计这一系列研究将导致确定一种可行的、微创的、 有效干预解决这一弱势群体的疲劳和睡眠问题，从而 生活质量和结果的改善。
