DUBLIN, Sept. 24, 2020 /PRNewswire/ -- Endo International plc (NASDAQ:ENDP) today announced that it will present data relevant to the use of Qwo™ (collagenase clostridium histolyticum-aaes) for the treatment of moderate to severe cellulite in the buttocks of adult women during Vegas Cosmetic Surgery & Aesthetic Dermatology (VCS). This data will be highlighted in two oral presentations during the virtual VCS symposium taking place September 24 – 27, 2020.

On Thursday, September 24^th a presentation titled "Injectable Cellulite Treatment," will be given by Michael Gold, M.D., F.A.A.D., a board-certified dermatologist in Nashville, TN. This presentation will include a general overview of collagenase clostridium histolyticum-aaes and will review data from the product's phase 3 pooled trial analyses.

On Saturday, September 26^thSachin M. Shridharani, M.D., F.A.C.S., will present "Injectable Cellulite Treatment - Collagenase Clostridium Histolyticum-aaes Effect on Tissue Histology." During this presentation, Dr. Shridharani, a board-certified plastic surgeon in New York, NY, will outline findings from two new histology studies that were designed to characterize QWO's subdermal impact and investigate the most frequently reported adverse event, injection site bruising.

The data being presented by Dr. Shridharani introduces Enzymatic Subcision and Remodeling™ (ESR™), which is thought to be a key component of collagenase clostridium histolyticum-aaes' mechanism of action. QWO breaks down the mature, collagen-rich septae which are one cause of cellulite dimples and stimulates the onset of new collagen for a smoother looking appearance^1,2.

"We are pleased that these data will be presented at Vegas Cosmetic Surgery & Aesthetic Dermatology, and as we prepare to launch QWO in spring 2021, we are committed to ensuring aesthetic healthcare providers have continued access to relevant research on the product," said Matthew Davis, M.D., R.Ph., Senior Vice President and Chief Medical Officer of Endo.

INDICATION
QWO is indicated for the treatment of moderate to severe cellulite in the buttocks of adult women.

IMPORTANT SAFETY INFORMATION FOR QWO CONTRAINDICATIONS
QWO is contraindicated in patients with a history of hypersensitivity to collagenase or to any of the excipients or the presence of infection at the injection sites.

WARNINGS AND PRECAUTIONS
Hypersensitivity Reactions
Serious hypersensitivity reactions including anaphylaxis have been reported with the use of collagenase clostridium histolyticum. If such a reaction occurs, further injection of QWO should be discontinued and appropriate medical therapy immediately instituted. Advise patients to seek immediate medical attention if they experience any symptoms of serious hypersensitivity reactions.

Injection Site Bruising
In clinical trials, 84% of subjects treated with QWO experienced injection site bruising. Subjects with coagulation disorders or using anticoagulant or antiplatelet medications (except those taking ≤150 mg aspirin daily) were excluded from participating in Trials 1 and 2.

QWO should be used with caution in patients with bleeding abnormalities or who are currently being treated with antiplatelet (except those taking ≤150 mg aspirin daily) or anticoagulant therapy.

Substitution of Collagenase Products
QWO must not be substituted with other injectable collagenase products. QWO is not intended for the treatment of Peyronie's Disease or Dupuytren's Contracture.

ADVERSE REACTIONS
In clinical trials, the most commonly reported adverse reactions in patients treated with QWO incidence ≥ 10% were at the injection site: bruising, pain, nodule and pruritus.

About Cellulite
Cellulite is a localized alteration in the contour of the skin that has been reported in over 90 percent of post-pubertal females and affects women of all races and ethnicities.^3,4 The presence of cellulite is associated with changes in dermal thickness and in the fat cells and connective tissue below the skin.⁵ A primary factor in the cause of the condition is the collagen containing septae which attach the skin to the underlying fascia layers.^6,7 The septae tether the skin which, with additional contributing protrusions of subcutaneous fat, causes the surface dimpling characteristic of cellulite.^8,9 These fibrous septae are oriented differently with varying thickness in females than in males, which informs our understanding of cellulite as a gender-related condition.¹⁰Cellulite clinically presents on the buttocks, thighs, lower abdomen and arms.

It is known that cellulite is different from generalized obesity.¹¹ In generalized obesity, adipocytes undergo hypertrophy and hyperplasia that is not limited to the pelvis, thighs, and abdomen.⁴ In areas of cellulite, characteristic large, metabolically stable adipocytes have physiologic and biochemical properties that differ from adipose tissue located elsewhere.¹² An anatomical study in 2019 found that women have increased fat lobule height compared with men, which may also contribute to the mattress-like appearance seen as a result of the tension of the fibrous septae.^10,12 Weight gain can make cellulite more noticeable, but cellulite may be present even in thin subjects.¹¹
