Long-term Safety Study of Buntanetap for Adults Aged 40 to 85 with Parkinsons Disease, Including Those with Deep Brain Stimulation Treatment

What this Trial Is About

Researchers are evaluating the long-term safety of buntanetap in people with Parkinsons Disease PD. This 36-month open-label study involves two groups one includes PD participants previously in buntanetap trials, and the other includes participants receiving deep brain stimulation DBS treatment. The study aims to monitor safety and adverse events related to buntanetap over an extended period. Qualified participants will take buntanetap capsules at a dose of 30 mg once daily after a screening period lasting up to 42 days. Cohort 1 includes those invited from prior buntanetap studies, while Cohort 2 consists of PD participants treated with DBS in specific brain areas for at least 12 months. Medication adjustments are required before visits to observe participants in an OFF medication state. Throughout the study, participants will have regular assessments conducted by trained clinicians using tools like MMSE, MoCA, C-SSRS, and MDS-UPDRS to evaluate cognitive and motor functions. Safety will be closely monitored, focusing on adverse events during the full 36 months. Support persons will accompany participants to visits, and medication stability and general health will be regularly evaluated to ensure study compliance and participant well-being.
