About this study
Official title: Phase 1-2, Multicenter, Randomized, Placebo-Controlled, Parallel-Group Study of the Safety and Efficacy of ATX-101 (Sodium Deoxycholate for Injection) for the Reduction of Subcutaneous Fat in the Submental Area
To evaluate the safety and potential efficacy of deoxycholic acid injection compared to placebo for the reduction of submental fat (fat below the chin).
Read the detailed description
The trial included an initial cohort (3 participants in each arm) to evaluate safety followed by expansion to a second, larger cohort if adequate safety was determined in the initial cohort. Data from both cohorts was pooled for analysis.
- Conditions
- Moderate or Severe Submental Fullness
- Being tested
- Deoxycholic Acid Injection, Placebo
- Medical subject headings
- Lymphoma, Follicular

Deoxycholic Acid InjectionDrug
Also called ATX-101
PlaceboDrug
| Study group | Role | What they receive |
|---|---|---|
| Deoxycholic Acid Injection 1 mg/cm² | Experimental | Participants received 0.5% deoxycholic acid administered in 0.2 mL injections, up to 4.8 mL (1 mg/cm²) per treatment session at intervals of approximately 1 month for up to a maximum of 4 treatments. Receives: Drug: Deoxycholic Acid Injection |

What is being measured
The primary outcome is the main question the study is designed to answer.
Number of Participants With Adverse Events
The investigator determined the relationship of each adverse event to the administration of study drug.
Severity of adverse events was determined using the following scale:
- Mild: The participant is aware of a sign or symptom, but it is easily tolerated
- Moderate: Discomfort or interference with usual activity
- Severe: Incapacitating, with inability to engage in usual activity.
A serious AE (SAE) was defined as an event that may constitute a significant medical hazard or side-effect, regardless of the investigator or sponsor's opinion regarding relatedness to study material. Serious events included, but were not limited to, any event that:
- was fatal
- was life-threatening
- required inpatient hospitalization or prolongation of existing hospitalization
- resulted in persistent or significant disability/incapacity
- was a congenital anomaly/birth defect
- other significant medical hazard
Measured: From the first dose of study drug until 12 weeks after the last dose (up to 24 weeks after first treatment).
Number of Participants With Clinically Significant Changes From Baseline in Laboratory Values, Weight, Vital Signs, and Physical Examinations
Measured: From the first dose of study drug until 12 weeks after the last dose (up to 24 weeks after first treatment).
Secondary outcomes (5)
Change From Baseline in Submental Fat (SMF) Rating Scale Score
The SMF rating scale 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.
A negative change from Baseline indicates improvement.
Measured: Baseline and 4 weeks after last treatment (up to 16 weeks after first dose)
Change From Baseline in Subject Satisfaction With Appearance Rating Scale
The Subject Satisfaction with Appearance Rating Scale assesses participants' satisfaction with their appearance in association with the face and chin on a 7-point scale from 0 to 6 where 0 = Extremely dissatisfied, 1 = Dissatisfied, 2 = Slightly dissatisfied, 3 = Neither satisfied nor dissatisfied, 4 = Slightly satisfied, 5 = Satisfied and 6 = Extremely satisfied. A positive change from Baseline indicates improvement.
Measured: Baseline and 4 weeks after last treatment (up to 16 weeks after first dose)
Percentage of Participants With a Response in the Subject Global Improvement Rating
Participants were asked to rate their total improvement or worsening in the appearance and physical feeling of their chin and neck area since before they received study treatment, whether or not they believed it was due to study treatment or to any other cause.
0 = Very much worse, 1 = Much worse, 2 = Minimally worse, 3 = No change, 4 = Minimally improved, 5 = Much improved, 6 = Very much improved.
Response is defined as any improvement, ie, a global improvement rating of 4, 5, or 6.
Measured: 4 weeks after last treatment (up to 16 weeks after first dose)
Change From Baseline in Skin Laxity Rating
Skin laxity assessment was based on clinical evaluation and palpation of the submental area on the following scale:
1 = no laxity; 2 = minimal laxity; 3 = moderate laxity; 4 = very lax. A negative change from Baseline indicates improvement.
Measured: Baseline and Week 4, Week 8, Week 12, Week 16 (4 weeks after last treatment) and Week 24 (12 weeks after last treatment)
Change From Baseline in the Cervicomental Angle
The cervicomental angle was measured using a profile view photograph obtained at each visit. A goniometer was used to determine the angle. Cervicomental angle measurements less than 80 degrees are excluded, due to error in measurement.
Measured: Baseline and 4 weeks after last treatment (up to 16 weeks after first dose)

Questions about this trial
What is this clinical trial studying?
A Phase 1/2 study testing Deoxycholic Acid Injection in people with Moderate or Severe Submental Fullness, run by Kythera Biopharmaceuticals at 6 sites in 3 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 3 inclusion and 4 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 14 Jul 2015. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 6 sites in Australia, Canada, United Kingdom. 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 combined 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.
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 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?
Number of Participants With Adverse Events (time frame: From the first dose of study drug until 12 weeks after the last dose (up to 24 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?
On the ClinicalTrials.gov record for NCT00618722, which also lists 1 linked publication.
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.
