Brief 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).

Outcome Measures

Primary Outcomes (2)

• 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.

• 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.

Study Arms (3)

Cohort A

ACTIVE COMPARATOR

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.

Cohort B

ACTIVE COMPARATOR

The minimum dosage of QWO will be 0.92 mg, or 6 injections per treatment area (2 areas per treatment visit. Cohort B subjects will be given 1300 mg tranexamic acid PO TID prior to the day of the first and second CCH injections, the day of the first and second CCH injection, and the 3 days following the first and second CCH injections.

Cohort C subjects will be given 1300 mg tranexamic acid PO TID prior to the day of the first, second, and third CCH injections, the day of the first, second, and third CCH injection, and the 3 days following the first, second, and third CCH injections.
