A Study to Evaluate Sequential Administration of Injections of AGN-151586 Followed by BOTOX in Adult Participants for Treatment of Glabellar Lines
What this study is about
Facial lines that develop from repeated facial expression, such as glabellar lines (GL), are typically treated by selectively weakening specific muscles with small quantities of botulinum toxin. The purpose of this study is to assess how safe and effective sequential administration of AGN-151586 and OnabotulinumtoxinA (BOTOX) is in adult participants with moderate to severe GL.
View original scientific description
Facial lines that develop from repeated facial expression, such as glabellar lines (GL), are typically treated by selectively weakening specific muscles with small quantities of botulinum toxin. The purpose of this study is to assess how safe and effective sequential administration of AGN-151586 and OnabotulinumtoxinA (BOTOX) is in adult participants with moderate to severe GL. AGN-151586 is an investigational drug being developed for treatment of moderate to severe glabellar lines. Participants are placed into 1 of 2 groups called treatment arms. In both arms participants will receive both AGN-151586 and BOTOX. Approximately 120 adult participants with moderate to severe glabellar lines enrolled in the study in approximately 8 sites around the United States. Participants will receive injections of AGN-151586 on Day 1 in the glabellar complex. After meeting treatment criteria, participants in Cohort 1 will receive intramuscular injections of BOTOX on Day 14, and participants in Cohort 2 will receive intramuscular injections of BOTOX on Day 21. Participants will be followed for up to approximately 141 days.

Number of Participants with Adverse Events (AEs)
Time frame: Up to Approximately Day 141
An adverse event (AE) is defined as any untoward medical occurrence in a patient or clinical investigation participant administered a pharmaceutical product which does not necessarily have a causal relationship with this treatment. The investigator assesses the relationship of each event to the use of study drug and the study drug injection procedure.
Who can participate
This study lists these criteria on ClinicalTrials.gov. A study coordinator reviews eligibility during screening — this page does not determine whether you qualify.
Inclusion criteria
- Moderate or severe glabellar lines (GL) at maximum frown as assessed by both the investigator and participant using the Facial Wrinkle Scale (FWS) at Screening and Baseline (Day 1) Visits
- Must be in good health as per investigator's judgment based on medical history, physical examination, vital sign measurements, and 12-lead ECG parameters
- Must have sufficient visual acuity without the use of eyeglasses (contact lens use is acceptable) to accurately assess their GL, in the opinion of the investigator.
Exclusion criteria
- Severe glabellar lines at rest as assessed by the investigator using the FWS
- Prior exposure to botulinum neurotoxin of any serotype within the last 12 months prior to screening
- History of hypersensitivity to any botulinum neurotoxin serotype or any other constituents of the study drug

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
