A Trial to Evaluate the Safety, Tolerability and Preliminary Efficacy of NCR201 in the Treatment of Subjects With Parkinson's Disease

Parkinson's disease (PD) is a common neurodegenerative disease in the middle-aged and elderly. It is the "third killer" of the middle-aged and elderly after tumors and cardiovascular and cerebrovascular diseases. Its main clinical manifestations are resting tremor, reduced voluntary movement, muscle rigidity, postural reflex impairment, and autonomic dysfunction, which seriously affect patients' work ability and quality of life. It is estimated that nearly 100,000 people in China become new Parkinson's patients every year. Experts from the World Health Organization predict that the number of Parkinson's patients in China will reach 5 million in 2030, which will be more than half of the world's total. As the disease progresses, the symptoms of Parkinson's patients will become increasingly severe. The high prevalence and high disability rate of Parkinson's disease bring heavy burdens to individuals, families, and society.
