An Open Label Clinical Trial to Evaluate the Efficacy and Safety of Calculus Bovis Sativus (CBS) for Ischemic Cerebral Vascular Disease
The most common cause of death for Chinese patients is ischemic cerebrovascular diseases(ICVD), particularly cerebral infarction. It places a heavy burden on people, families, and society as a whole and poses considerable risks of death and disability. The disease known as CSVD has a subtle beginning, is difficult to identify, and is frequently detected only after it progresses to the point of vascular cognitive dysfunction. The primary ischemia necrosis of brain nerve cells and the activation of inflammatory cells are their pathologic processes. According to historical Chinese medical documents, bezoar possesses properties that can help prevent seizures, treat strokes, enhance cognitive function and mental well-being, and stimulate alertness. Calculus Bovis Sativus (CBS) is the most authentic formulation of bezoar ingredients compared to other bezoar products. It has received approval from the China Food and Drug Administration for the essential treatment of comatose patients. CBS consists of three primary constituents: bilirubin, bile acids, and taurine. Scientific evidence has demonstrated that all of these components possess anti-inflammatory, antioxidant, and neuroprotective properties. The investigators' objective is to carry out an investigator-initiated clinical study to assess the efficacy of orally administered CBS in treating ischemic cerebrovascular diseases in humans.
• ICVD cohort:
‣ Subjects are able to understand the purpose and risks of the study, provide informed consent, and authorize the use of confidential health information in accordance with national and local privacy regulations.
⁃ Both men and women are welcome, and the age at the time of providing informed consent is 18-80 years (inclusive).
⁃ All women of childbearing age and all men must use contraceptive measures during the study and for at least 30 days after the last dose of study treatment. In addition, subjects should not donate sperm or eggs during the study and for at least 30 days after the last dose of study treatment.
⁃ Must be diagnosed with
‣ ① Ischemic stroke, according to the Diagnosis Points of Various Cerebrovascular Diseases of the Fourth National Cerebrovascular Disease Academic Conference, the main clinical diagnosis is ischemic stroke (cerebral infarction), 1 point ≤ NIHSS ≤ 24 points, and mRS ≤ 3 points; or ② Cerebral small vessel disease, according to the results of conventional sequence MRI examination, Fazekas score on T2 FLAIR sequence ≥ 3 points (0-6 points, the sum of paraventricular WMH score + subcortical WMH score), and mRS ≤ 3 points (mRS ≤ 4 points for those with recent subcortical small infarction within 1 month).
⁃ Neurological examination showed stability within 30 days before baseline (visit 1).
• Healthy cohort:
