Objective:

To evaluate the efficacy, safety, and optimal dose of OBI-858 in treating moderate-to-severe glabellar lines, addressing unmet treatment needs.

Approach:
    Key Findings:
    • OBI-858 at 20U showed significantly better wrinkle reduction compared to 10U or placebo (p < 0.05).
    • Effects of OBI-858 lasted up to 24 weeks.
    • The treatment demonstrated rapid onset and sustained subject satisfaction.
    Interpretation:

    OBI-858 has a favorable safety profile and potential as a next-generation botulinum toxin for treating glabellar lines.

    Limitations:
    • Study conducted in a limited geographical area (Taiwan), which may affect generalizability.
    • Short follow-up duration of 24 weeks may not capture long-term effects, necessitating further research.
    Conclusion:

    OBI-858 shows promise for effective and long-lasting treatment of moderate-to-severe glabellar lines, warranting further investigation to confirm these findings.
