Study summary

The goal of this clinical trial is to test the safety and effectiveness of an injection study drug in decreasing bilateral flank adiposity.

The main question it aims to answer is:

•How safe and effective is the injection study drug in removing bilateral flank adiposity compared to a placebo?

Participants will be:

  • Be given injections every month for 5 months over the right and left flanks.
  • Be asked to be seen in the clinic for 13 visits and 3 phone call visits during a duration of 1 year.
Read the detailed description

Fifteen subjects with bilateral flank adiposity will be enrolled across 1-3 sites in the USA.

What researchers measure

Primary outcomes

  1. Volumetric measurements

    Change from Baseline until end of study. Volumetric measurements will be obtained on each right and left flanks thru a standard photographic assessment.

    Time frame: 24 weeks after final injection treatment

  2. Flank Skin Laxity Scale (FSLS)

    Change from Baseline on each flank after final treatment. Flank Skin Laxity Scale (FSLS) is a 4 point scale, with a score of 0 for no skin folds, and a score of 3 for severe or worse skin folds.A higher score means a worse outcome.

    Time frame: 24 weeks after final injection treatment

  3. Clinician Global Impression of Change (CGIC)

    Change from Baseline on each flank after final treatment. Clinician Global Impression of Change (CGIC) is a 7-point bi-directional scale with 1 as much improved and 7 as much worse.

    Time frame: 24 weeks after final injection treatment

  4. Patient Global Impression of Change (PGIC)

    Change from Baseline on each flank after final treatment. Patient Global Impression of Change (PGIC) is a 7-point bi-directional scale with 1 as much improved and 7 as much worse.

    Time frame: 24 weeks after final injection treatment
