Effects of Mitigation Treatments on Bruising of CCH-aaes Treatment of Buttock Cellulite
Condition: Edematous Fibrosclerotic Panniculopathy (EFP); Cellulite
MeSH terms: Cellulite; Contusions
Intervention: CCH-aaes; Compression; Cold Packs; Arnica Gel; INhance®; PDL
Intervention description: Participants were administered CCH-aaes by subcutaneous injection to both buttocks.; Participants used a compression garment on both buttocks following subcutaneous CCH-aaes injections.; Participants used cold packs applied to the right buttock for 5-10 minutes immediately after subcutaneous CCH-aaes injections.; Participants used Arnica Gel Patches (Arnica montana 50% and Ledum palustre) immediately after the CCH-aaes injection to the right buttock.; Participants used INhance Post-injection Serum topically immediately after the CCH-aaes injection to the right buttock.; Investigators applied one treatment with PDL to the right buttock between days 1-7 after injection.

Summary:

      This study will investigate treatments that may mitigate bruising after QWO™ (Collagenase
      clostridium histolyticum [CCH]-aaes) treatment of cellulite in the buttocks.
    

Eligibility criteria:

        Key Inclusion Criteria:

          1. Have both buttocks with:

               1. Clinician Reported Photonumeric Cellulite Severity Scale (CR-PCSS) score of 3
                  (moderate) as reported by the Investigator, and

               2. Hexsel Cellulite Severity Scale (CSS) Subsection D "Grade of laxity, flaccidity,
                  or sagging skin" score of 0 (absence of laxity, flaccidity, or sagging skin) or 1
                  (slightly draped appearance).

          2. Have a body mass index between ≥18 and ≤30 kilograms (kg)/square meter (m^2).

          3. Be willing to apply sunscreen before each exposure to the sun while participating in
             the study (that is, Baseline through end of study).

          2. Has local conditions in the areas to be treated (thrombosis, vascular disorder, active
             infection/inflammation, active cutaneous alteration, tattoo/mole) that restricts study
             participation.

          3. Has skin laxity or linear undulations on buttocks that can be effaced by lifting skin.

          4. Requires the following concomitant medications during the study and cannot discontinue
             these medications within the time specified before CCH-aaes treatment.

               1. Antiplatelet medication (clopidogrel [Plavix®] including aspirin at any dose
                  within 14 days of treatment.

             applications/therapies/injections/procedures that restricts study participation.
