Endo Aesthetics Data to be Featured in Five Presentations at the American Society for Dermatologic Surgery's Annual Meeting (ASDS)

October 9, 2020

DUBLIN, Oct. 9, 2020 /CNW/ -- Endo International plc (NASDAQ:ENDP) today announced that data relevant to the use of Endo Aesthetics' Qwo™ (collagenase clostridium histolyticum-aaes) for the treatment of moderate to severe cellulite in the buttocks of adult women will be featured during the American Society for Dermatologic Surgery's Annual Meeting (ASDS). These data will be highlighted in three posters and two oral presentations during the virtual meeting taking place October 9 – 11, 2020.

Oral Presentations

On Friday, October 9th a presentation titled "Results From a 1000+ Subject Survey Assessing Satisfaction With a Hypothetical 1-Point Improvement on the Validated Patient-Reported Photonumeric Cellulite Severity Scale (PR-PCSS) Analysis," will be given by Sabrina Fabi, M.D., a board-certified dermatologist in California. Dr. Fabi will share results from a study designed to determine if a 1-point improvement in PR-PCSS score is a clinically meaningful outcome and will highlight the importance of patient education during consultations.

On Sunday, October 11th, Melanie Palm, M.D., will present "Real-World Effectiveness and Safety of Collagenase Clostridium Histolyticum-aaes Injections for the Treatment of Thigh Cellulite in Women: An Interim Analysis". During this presentation, Dr. Palm, a board-certified dermatologist and cosmetic surgeon in California, will outline the 90-day findings from ongoing phase 3b REAL™ and PIXELS™ studies assessing not only investigator-perceived and patient-reported results at 90-days, but also the quantitative corroboration of these findings, with 3D-image scans.

Poster Presentations

All poster presentations will be available for ASDS attendees throughout the Congress.

"We are pleased with the breadth and depth of the data that will be presented at the ASDS meeting," said Matthew Davis, M.D., R.Ph., Senior Vice President and Chief Medical Officer of Endo. "Endo Aesthetics is committed to offering aesthetic healthcare providers data not only on the safety and efficacy of QWO, but also on the real world implications of this treatment, including patient retention and perceptions, as we prepare for the product's launch in spring 2021."

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

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.

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 Dupuytrens Contracture.

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.1,2 The presence of cellulite is associated with changes in dermal thickness and in the fat cells and connective tissue below the skin.3 A primary factor in the cause of the condition is the collagen containing septae which attach the skin to the underlying fascia layers.4,5 The septae tether the skin which, with additional contributing protrusions of subcutaneous fat, causes the surface dimpling characteristic of cellulite.6,7 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.Cellulite clinically presents on the buttocks, thighs, lower abdomen and arms. 

It is known that cellulite is different from generalized obesity.9 In generalized obesity, adipocytes undergo hypertrophy and hyperplasia that is not limited to the pelvis, thighs, and abdomen.2 In areas of cellulite, characteristic large, metabolically stable adipocytes have physiologic and biochemical properties that differ from adipose tissue located elsewhere.10 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.8,10  Weight gain can make cellulite more noticeable, but cellulite may be present even in thin subjects.9
