- Moderate or Severe Submental Fullness
- Being tested
- Deoxycholic acid injection, Placebo
- Medical subject headings
- Lymphoma, Follicular
What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Deoxycholic acid injectionDrug
Also called ATX-101, Kybella
Formulated as an injectable solution containing deoxycholic acid at a concentration of 10 mg/mL.
PlaceboDrug
Phosphate buffered saline placebo for injection
| Study group | Role | What they receive |
|---|---|---|
| Placebo | Placebo comparator | Participants received placebo administered in 0.2 mL injections, up to 10 mL per treatment session at intervals of approximately 1 month for up to a maximum of 6 treatments. Receives: Drug: Placebo |
| Deoxycholic Acid Injection | Experimental | Participants received deoxycholic acid 2 mg/cm² administered in 0.2 mL injections, up to 10 mL per treatment session at intervals of approximately 1 month for up to a maximum of 6 treatments. Receives: Drug: Deoxycholic acid injection |
What is being measured
The primary outcome is the main question the study is designed to answer.
Percentage of Participants Who Achieved a Composite 1-grade Response
A composite 1-grade response is defined as at least a 1-grade improvement from Baseline on both the Clinician-Reported Submental Fat Rating Scale (CR-SMFRS) and Patient-Reported Submental Fat Rating Scale (PR-SMFRS) 12 weeks after the last treatment.
The CR-SMFRS score is based on the investigator's clinical evaluation of the participant, where submental fullness is scored on a 5-point ordinal scale (0-4) with 0 = absent, 1 = mild, 2 = moderate, 3 = severe, and 4 = extreme.
The PR-SMFRS is based on the participant's response to the question "How much fat do you have under your chin right now?" answered on a 5-point ordinal scale (0-4) with 0 = no chin fat at all, 1 = a slight amount of chin fat, 2 = a moderate amount of chin fat, 3 = a large amount of chin fat, and 4 = a very large amount of chin fat.
Measured: Baseline and 12 weeks after last treatment (up to 32 weeks after first treatment)
Percentage of Participants Who Achieved a Composite 2-grade Response
A composite 2-grade response is defined as at least a 2-grade improvement from Baseline on both the Clinician-Reported Submental Fat Rating Scale (CR-SMFRS) and Patient-Reported Submental Fat Rating Scale (PR-SMFRS) 12 weeks after the last treatment.
The CR-SMFRS score is based on the investigator's clinical evaluation of the participant, where submental fullness is scored on a 5-point ordinal scale (0-4) with 0 = absent, 1 = mild, 2 = moderate, 3 = severe, and 4 = extreme.
The PR-SMFRS is based on the participant's response to the question "How much fat do you have under your chin right now?" answered on a 5-point ordinal scale (0-4) with 0 = no chin fat at all, 1 = a slight amount of chin fat, 2 = a moderate amount of chin fat, 3 = a large amount of chin fat, and 4 = a very large amount of chin fat.
Measured: Baseline and 12 weeks after last treatment (up to 32 weeks after first treatment)
Secondary outcomes (2)
Percentage of Participants With a Magnetic Resonance Imaging (MRI) Response
An MRI responder is a participant who exhibited at least a 10% reduction in submental fat volume as measured by MRI from Baseline to 12 weeks after last treatment. Magnetic resonance imaging was evaluated in a subset of participants at selected centers.
Measured: Baseline and 12 weeks after last treatment (up to 32 weeks after first treatment)
Change From Baseline in Patient-Reported Submental Fat Impact Scale (PR-SMFIS)
The PR-SMFIS assesses the impact of submental fat on self-perception of 6 emotional and visual characteristics related to the appearance of submental fullness (unhappy, bothered, self-conscious, embarrassed, look older, and look overweight) as evaluated by the participant. Each item is rated on an 11-point numeric scale from 0 to 10. Scores for the 6 items were averaged to generate a PR-SMFIS total scale score ranging from 0 to 10 where 0 is a positive outcome and 10 is a negative outcome. A negative change from Baseline indicates improvement.
Measured: Baseline and 12 weeks after last treatment (up to 32 weeks after first treatment)

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing Deoxycholic acid injection in people with Moderate or Severe Submental Fullness, run by Kythera Biopharmaceuticals at 35 sites in 2 countries.
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 8 inclusion and 15 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 15 Jun 2015. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 35 sites in United States, Canada. 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 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.
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 15 Jun 2015). 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?
Percentage of Participants Who Achieved a Composite 1-grade Response (time frame: Baseline and 12 weeks after last treatment (up to 32 weeks after first treatment)). The study lists 2 primary outcomes in all. 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 15 Jun 2015.
