What this Trial Is About

Researchers are evaluating the use of Calculus Bovis Sativus (CBS), a traditional Chinese medicine, for adults with encephalitis, a condition involving inflammation of the brain. This trial focuses on both infectious and autoimmune encephalitis types, including anti-NMDAR and LGI-1 autoimmune encephalitis. CBS is thought to have neuroprotective and anti-inflammatory effects by influencing gut microbiota and the brain-gut connection, potentially improving symptoms like seizures, consciousness, and cognitive function. Participants are divided into groups receiving either general therapy plus CBS, general therapy alone, or CBS alone if healthy. CBS is given orally at 100 mg daily for 84 days. The study is open-label and non-randomized, with some participants being healthy volunteers receiving only CBS. This design allows comparison of CBS effects in encephalitis patients and healthy individuals. During the study, participants will be monitored for neurological and cognitive changes using tools like the Modified Rankin Scale and Clinical Assessment Scale in Autoimmune Encephalitis over 12 weeks. Brain imaging, EEG, and assessments of mental state, anxiety, depression, and quality of life will also be conducted. Safety evaluations include tracking adverse effects up to 14 weeks. The study lasts up to 14 weeks from treatment start, with assessments at multiple timepoints.

  • Stable neurological exam within 30 days before baseline
  • Meet specific diagnostic and symptom criteria for NMDAR or LGI-1 encephalitis if applicable
Not Eligible

You will not qualify if you...

  • Significant cardiac, endocrine, hematologic, hepatic, immune, infectious, metabolic, pulmonary, neurological, psychiatric, renal, or other major diseases
  • Untreated tumors or malignancies at baseline
