What is being measured
The primary outcome is the main question the study is designed to answer.
Number of Participants With a Response Defined as IGA-C (Investigators Global Assessment) Score ≤ 2 and a SSA-C (Subject Self-Assessment) Score ≤ 2
Composite of Investigators Global Assessment \& Subject Self-Assessment on contraction.
Crow's Feet Wrinkle Scale where severity is scored between 0-4 (0=absent; 4=severe). The same scale is used for the Investigator's Assessment as well as the Subject's Self Assessment. To count, both assessments (on contraction) have to be "responders" defined as Score ≤ 2.
Measured: Week 4
Secondary outcomes (2)
Total Number of Observations With a Response Defined as IGA-C Score ≤ 2
Total number of observations with a Score of ≤ 2 on the Investigators Global Assessment on Contraction, IGA-C, using the Crow's Feet Wrinkle Scale, where severity is scored between 0-4 (0=absent; 4=severe). To count, a "responder" is defined as Score ≤ 2. The observation period ranges from the earliest expected onset of action at Week 2 to the likely offset of action by Week 18.
Measured: Week 2, 4, 8,12,18
Total Number of Observations With a Response Defined as SSA-C Score ≤ 2
Total number of observations with a Score of ≤ 2 on the Subject Self-Assessment on Contraction, SSA-C, using the Crow's Feet Wrinkle Scale, where severity is scored between 0-4 (0=absent; 4=severe). To count, a "responder" is defined as Score ≤ 2. The observation period ranges from the earliest expected onset of action at Week 2 to the likely offset of action by Week 18.
Measured: Week 2, 4, 8,12,18

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing botulinum toxin, Type A in people with Lateral Canthal Lines and Crow's Feet, run by Eirion Therapeutics Inc. at 1 site in United States.
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 5 inclusion and 8 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 21 Apr 2022. 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 United States. 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 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Yes. Results are posted in the registry (first posted 10 Sep 2021). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
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?
Number of Participants With a Response Defined as IGA-C (Investigators Global Assessment) Score ≤ 2 and a SSA-C (Subject Self-Assessment) Score ≤ 2 (time frame: Week 4). 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 21 Apr 2022.
