Study summary

The purpose of this research is to compare the safety and effectiveness of 3 different concentrations of deoxycholic acid for injection against a placebo in the treatment of superficial lipomas.

Read the detailed description

A lipoma is a fatty lump typically located on the trunk, shoulder, arms, or legs. For the purposes of this study, only lipomas on the trunk, arms, legs, or neck were treated. (Lipomas on the face, wrists, hands, lower portion of the spine, genitals, ankles, or feet were not treated.)

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  • One or more lipomas, based on clinical and histological diagnosis, which are accessible for treatment and assessment, are quantifiable along at least 2 perpendicular diameters, and have the following characteristics:

    • History of slow growth followed by dormancy, and stable for at least 6 months
    • Greatest length multiplied by greatest perpendicular width between 1 and 16 cm², inclusive
    • Discrete, oval to rounded in shape, not hard or attached to underlying tissue
    • Without changes in overlying skin (ie, inflammation, pain or tenderness, hyperpigmentation)
    • Located on the trunk, arms, legs, or neck
  • Signed .

Exclusion criteria

Exclusion Criteria:

  • Absence of significant medical conditions that could affect safety
  • History of surgical or deoxycholate treatment for lipomas
  • Treatment with an agent within 30 days before ATX-101 treatment
Terms in these criteria, in plain language(2)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Investigational drug or device

A drug or device being studied in a clinical trial.

It may be new, or already approved and being studied for another use, dose or form. Criteria often leave out people who took part in another study of one within a recent period, commonly 30 days or five half-lives.

What researchers measure

Primary outcomes

  1. Number of Participants With Adverse Events (AEs)

    Severity of AEs was determined using the following scale: Mild: The participant was aware of a sign or symptom, but it was easily tolerated; Moderate: Discomfort or interference with usual activity; Severe: Incapacitating, with inability to engage in usual activity. The investigator determined the relationship of each AE to the administration of study material by answering the question: "Was there a reasonable possibility that the event may have been caused by treatment with study material?" A serious AE was an event that constituted a significant medical hazard or side effect, regardless of the investigator's or sponsor's opinion regarding relatedness to study material. Serious AEs included any event that was fatal or life-threatening, required inpatient hospitalization or prolongation of existing hospitalization, resulted in persistent or significant disability/incapacity, was a congenital anomaly/birth defect or other significant medical hazard.

    Time frame: Up to 24 weeks

  2. Number of Participants With Newly Occurring or Worsening Biochemistry/Hematology/Urinalysis Abnormalities

    An abnormality is defined as a value outside the limits of the expanded normal range/notable range.

    Time frame: 24 weeks

  3. Number of Participants With Clinically Significant Changes in Vital Signs or Weight

    Time frame: Up to 24 weeks

  4. Number of Participants With Positive Histopathology Results at Screening

    A needle core tissue sample biopsy was performed at screening for all treated lipomas.

    Time frame: Screening (prior to randomization)

  5. Number of Participants With Positive Histopathology Results at Week 20

    After the completion of all tests and procedures scheduled for week 20, participants with treated lipomas that remained palpable could have their treated lipomas excised.

    Time frame: Week 20

Secondary outcomes

  1. Percentage of Participants With Complete Clearance or ≥ 75% Clearance

    At randomization 1 to 3 lipomas were selected for treatment. Lipomas were measured in 3 dimensions (longest length, perpendicular width, and height if possible) using digital calipers. Complete clearance indicates target lipoma(s) not present or detectable, and ≥ 75% clearance is defined as a ≥ 75% reduction from baseline in the area of target lipoma(s). For participants with \> 1 target lipoma, the total area of all target lipomas was used in the calculation of response.

    Time frame: Baseline and week 20 (8 weeks after last dose)

  2. Percent Change From Baseline in the Sum of the Areas of All Treated Lipomas

    Percent change from baseline was calculated as the baseline total lipoma area - postbaseline total lipoma area / baseline total lipoma area \* 100. A positive change indicates a reduction in size.

    Time frame: Baseline and week 12 (last treatment session), week 16 (4 weeks after last treatment), and week 20 (8 weeks after last treatment)

Timeline

Tracking since Sep 25, 2026
Not marked actual or estimatedDates not marked actual or estimated

The record gives a start of Nov 2007, a primary completion of Aug 2008 and a completion of Jan 2010. It does not say whether these dates are actual or estimated.

Results were first posted in Jan 2016, 7 years 5 months after primary completion. A results delay was requested in May 2014.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Jan 14, 2016, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
