About this study

Official title: A Phase 1/2, Randomized, Double-Blinded, Placebo-Controlled Study of AGN-151586 in the Treatment of Japanese Subjects With Moderate to Severe Glabellar Lines

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 evaluate the safety and efficacy of AGN-151586 over a range of doses for the treatment of moderate to severe GL in Japanese participants.

AGN-151586 is an investigational product being developed for the treatment of GL. Participants are randomly assigned to receive AGN-151586 or placebo. There is 1 in a 4 chance that participants will receive placebo. Around 24 adult participants with moderate to severe GL will be enrolled in the study in approximately 2 sites in Japan.

Participants will receive either AGN-151586 or Placebo administered as 5 intramuscular injections to the glabellar complex on Day 1. The duration of the study will be approximately 6 weeks.

There may be higher treatment burden for participants in this trial compared to their standard of care. Participants will attend regular visits during the study at a hospital or clinic. The effect of the treatment will be checked by medical assessments, blood tests, checking for side effects and completing questionnaires.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Percentage of participants with a >= 2-grade improvement from baseline on the Facial Wrinkle Scale with Asian (FWS-A) Guide according to investigator assessment of Glabellar Lines (GL) severity at maximum frown, at any timepoint through Day 7

    Investigators' assessments of the severity of GL using the 4-grade FWS-A, where 0=none and 3=severe. Higher grades indicate more severity.

    Measured: Baseline (Day 1) through Day 7

Secondary outcomes (3)
  1. Percentage of participants with a >= 2-grade improvement from baseline on the FWS-A according to investigator assessment of GL severity at maximum frown over time

    Investigators' assessments of the severity of GL using the 4-grade FWS-A, where 0=none and 3=severe. Higher grades indicate more severity.

    Measured: Baseline (Day 1) through End of Study (Up to Day 42)

  2. Percentage of participants with a >= 1-grade improvement from baseline on the FWS-A according to investigator assessment of GL severity at maximum frown over time

    Investigators' assessments of the severity of GL using the 4-grade FWS-A, where 0=none and 3=severe. Higher grades indicate more severity.

    Measured: Baseline (Day 1) through End of Study (Up to Day 42)

  3. Percentage of participants with a None or Mild on the FWS-A according to investigator assessment of GL severity at maximum frown over time

    Investigators' assessments of the severity of GL using the 4-grade FWS-A, where 0=none and 3=severe. Higher grades indicate more severity.

    Measured: Baseline (Day 1) through End of Study (Up to Day 42)

Individual data sharing
Yes: AbbVie is committed to responsible data sharing regarding the clinical trials we sponsor. This includes access to anonymized, individual and trial-level data (analysis data sets), as well as other information (e.g., protocols, analyses plans, clinical study reports), as long as the trials are not part of an ongoing or planned regulatory submission. This includes requests for clinical trial data for unlicensed products and indications.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing AGN-151586 in people with Moderate to Severe Glabellar Lines, run by AbbVie at 1 site in Japan.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 2 inclusion and 10 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 26 Jun 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Japan. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Percentage of participants with a >= 2-grade improvement from baseline on the Facial Wrinkle Scale with Asian (FWS-A) Guide according to investigator assessment of Glabellar Lines (GL) severity at maximum frown, at any timepoint through Day 7 (time frame: Baseline (Day 1) through Day 7). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 26 Jun 2026.
