Cancer poses a severe threat to human physical and mental health as well as survival. High diagnostic rates of cancer and various treatments can significantly impact patients' sleep quality, leading to diverse sleep disorders. Cancer-related insomnia (CRI) is a prevalent sleep disturbance among cancer patients, potentially associated with the tumor itself, treatment modalities (such as surgery, chemotherapy, radiotherapy), psychological status, pain, fatigue, and other symptoms. Although reported incidence rates vary across studies, CRI is consistently high and severely compromises patients' quality of life. Core symptoms include difficulty falling asleep, sleep maintenance difficulties, and early morning awakening, which contribute to daytime fatigue, impaired concentration and memory, ultimately detrimentally affecting patients' health and quality of life. The pathogenesis of CRI is complex, potentially involving multiple factors including the tumor's direct effects, treatment side effects, psychological distress, pain, and fatigue.
The primary component of Ciwujia capsules (containing Eleutherococcus senticosus extract) is Ciwujia extract. To clarify the clinical efficacy of Ciwujia capsules for cancer-related insomnia in real-world clinical settings, this study will employ a multicenter, prospective, open-label, real-world research design. It is projected to involve 30-50 centers over an approximate 3-year trial period, with a planned enrollment of 3,000 subjects. Changes in sleep-related indicators before and after treatment will serve as the primary endpoint observation metrics. The study aims to investigate the clinical efficacy and safety profile of Ciwujia capsules in treating insomnia disorders in cancer patients, thereby providing robust evidence for identifying effective Chinese herbal medicine therapies for sedation and sleep promotion.
