Chinese Herbal Therapy (Qiqi Shengmai Formula) for Moyamoya Vasculopathy: The CHIMES Trial
Sponsor: Fudan University
Summary
Patients diagnosed with moyamoya vasculopathy by imaging and classified as having the Traditional Chinese Medicine (TCM) syndrome of liver-yang hyperactivity will be enrolled. On the basis of standardized Western medical management, participants will receive the standardized TCM herbal formula "Qiqi Shengmai Formula" (comprising Astragali Radix, Rehmanniae Radix Praeparata, Schisandrae Fructus, Bupleuri Radix, Paeoniae Radix Alba, and Notoginseng Radix). Structured follow-up will be conducted. By comparing endpoint indicators across different treatment regimens, the study aims to evaluate the efficacy of integrated TCM-Western medicine therapy for moyamoya vasculopathy and to generate evidence-based support for an integrated diagnostic and therapeutic model.

Traditional Chinese Medicine (TCM) Treatment
Patients receive the standardized TCM formula Qiqi Shengmai Decoction (composed of Astragali Radix, Rehmanniae Radix Praeparata, Schisandrae Fructus, Bupleuri Radix, Paeoniae Radix Alba, and Notoginseng Radix). The prescription is taken twice daily, one dose per administration, for six consecutive weeks, with each dose consumed 30 minutes after breakfast and dinner
Conventional medical treatment
For ischemic-type moyamoya disease, antiplatelet monotherapy with cilostazol is administered, while antiplatelet therapy is not recommended for asymptomatic patients or those with hemorrhagic-type moyamoya disease. For patients with concomitant dyslipidemia, statins and evolocumab may be added, with low-density lipoprotein cholesterol controlled to 70 mg/dL (1.8 mmol/L). Blood pressure is maintained at 140/90 mmHg, and glycemic management targets a hemoglobin A1c level of \<7.0%.
TCM Placebo
The placebo consists primarily of medicinal starch, food-grade caramel coloring (for color correction), and a bittering agent (for flavor adjustment). Its appearance-including shape, size, color, and taste-is identical to that of the herbal preparation. It is administered twice daily, one dose at each administration, for six consecutive weeks, taken 30 minutes after breakfast and dinner.
