A Phase I/II, Randomized, Double-blind, Placebo, and Active Controlled Clinical Study to Evaluate the Safety, Tolerability, Immunogenicity, and Preliminary Efficacy of JHM03 in Subjects With Moderate to Severe Glabellar Lines

This is a phase 1/2, multicenter, randomized, double-blind, active-controlled and placebo-controlled study to evaluate safety, immunogenicity and efficacy of JHM03 for the treatment of moderate to severe glabellar lines in male and female subjects of Chinese origin. The purpose of this study was to observe efficacy and safety of JHM03 compared with placebo and BOTOX® in moderate to severe glabellar lines.

Inclusion Criteria:

1. Male or female subjects between 18 and 65 years of age.

2. Use of medications that affect neuromuscular transmission within 4 weeks prior to screening, such as muscle relaxant,aminoglycoside antibiotics,anticholinergic drugs,benzodiazepines,etc.
3. Suffering from any neurological disorders that increase the risk of exposure to botulinum toxin type A, including peripheral motor nerve diseases (such as amyotrophic lateral sclerosis and motor neuropathy), as well as neuromuscular junction diseases (such as Lambert-Eaton syndrome and myasthenia gravis).
4. Known allergy or hypersensitivity to any component of the study products.
5. Use of any non-steroid anti-inflammatory drug or anticoagulant within 1 week prior to study treatment.
