Study summary

This is an open-label, randomized, multiple dose IIR study to evaluate the effect of Lysteda™ on bruising following QWO™ injections to the buttocks in female subjects presenting with moderate to severe cellulite.

Following determination of eligibility based on inclusion/exclusion assessment, the subjects will be randomized to either Cohort A, Cohort B, or Cohort C, based on order of enrollment. Each Cohort will receive 3 Qwo™ treatments spaced 21 days apart, with 1300 mg of Lysteda™ TID PO at one, two, or all three treatments of Qwo™. Cohort A will be given tranexamic acid at the first treatment, Cohort B at the first and second treatment, and Cohort C at all three treatments. All buttock CCH injections will follow the on-label injection protocol.

Subjects will participate in the study for 65 days total, with an additional screening period of 14 days. There will be a total of 11 visits (Screening, Day 1, Day 4, Day 14, Day 22, Day 26, Day 36, Day 43, Day 47, Day 57, Day 65).

Inclusion criteria

  • Female > 18 and \< 55 years of age.
  • At the screening visit, have buttocks with moderate to severe cellulite based on the CR-PCSS.
  • Be willing and able to comply with all protocol required visits and assessments.
  • Be willing to apply sunscreen to the treatment areas before each exposure to the sun for the duration of the study.
  • Is willing to refrain from exercise for 24 hours following each treatment.
  • Be adequately informed and understand the nature and risks of the study.

Exclusion criteria

Exclusion.

  • Has a history of or allergy to collagenase of any other of CCH.
  • At the screening visit, has none, almost none, or mild cellulite.
  • At the screening visit, per the investigator, has cellulite that would require less than 6 injections per buttock, or more than 12 injections per buttock.
  • Is pregnant and/or is breast-feeding or plans to become pregnant and/or to breast-feed during the course of the study, or 28 days after the last treatment.
  • Is currently undergoing hormone replacement therapy or has undergone hormone replacement therapy in the past 6 months.
  • Has a coagulation disorder which requires anticoagulant or antiplatelet medication during the study, or has taken anticoagulant or antiplatelet medication within 14 days before injections.
  • Is currently taking oral pills.
  • Is currently a smoker, or has smoked within the last year prior to screening.
  • Has a history of scarring due to keloids or abnormal wound healing.
  • Has received previous treatment with CCH for cellulite, or any other cellulite treatment.
  • Subject has any history of anemia or taking iron pills.
Terms in these criteria, in plain language(3)

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.

Hypersensitivity

An allergy, or another reaction of the immune system, to a substance. “Hypersensitivity to the study drug” means a known allergic reaction to it — not every side effect a medicine can have.

Excipients

The other ingredients in a medicine besides the active drug, such as fillers, colours or preservatives.

Contraception

Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.

Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.

Study arms

  • Active comparator
    Cohort A

    Per treatment area, subjects will be injected with up to 0.84 mg of QWO as 12 subcutaneous injections (0.3-mL injection administered as three 0.1-mL aliquots per injection), dependent on the amount of dimples (0.3 ml per dimple). A treatment area is defined as a left or right buttock, so patients may receive up to 1.84 mg, or 24 injections total (2 areas per treatment visit). The minimum dosage of QWO will be 0.92 mg, or 6 injections per treatment area (2 areas per treatment visit. Cohort A subjects will be given 1300 mg tranexamic acid PO TID prior to the day of the first CCH injections, the day of the first CCH injections, and the 3 days following the first CCH injections.

What researchers measure

Primary outcomes

  1. Post CCH injection degree of bruising with TXA based on the Investigator Assessment of Bruising Severity Scale

    Scale assessments completed at each follow-up visit. Bruising scale is 0-4, with 0 being no bruise and 4 being the worst bruise possible. A lower number on the bruising scales indicates a better outcome.

    Time frame: 6 months

  2. Post CCH injection degree of bruising with TXA based on Investigator Bruising Improvement Scale (I-BIS).

    Scale assessments completed at each follow-up visit. Bruising scale is 0-4, with 0 being no bruise and 4 being the worst bruise possible. A lower number on the bruising scales indicates a better outcome.

    Time frame: 6 months
