DUBLIN, April 29, 2021 / PRNewswire / – Endo International plc (NASDAQ: ENDP) today announced that Endo Aesthetics’ Qwo usage data® (collagenase clostridium histolyticum-aaes), which received FDA approval in July 2020 for the treatment of moderate to severe cellulitis of the buttocks of adult women, will be presented during The 2021 aesthetic encounter.

This data will be highlighted during two oral presentations during the virtual and in-person meeting that will take place in Miami, Florida April 29 to May 3, 2021.

  • “Reduction of dimple size in women with cellulitis of the buttocks treated with Clostridium Histolyticum-aaes collagenase”; Lawrence bass, MD, Medical Director and Founder, Bass Plastic Surgery, PLLC and QWO Clinical Trials Investigator; Sunday May 2
  • “Real-world efficacy and safety of Clostridium histolyticum-aaes collagenase injections for the treatment of thigh cellulitis in women: an interim review”; Sachin shridharani, MD, FACS, founder, LUXURGERY©, and investigator of the QWO clinical trial; Sunday May 2

QWO will also be discussed during The Aesthetic Meeting’s highly respected Premier Global Hot Topics program on Friday April 30.

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


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

Hypersensitivity reactions
Serious hypersensitivity reactions, including anaphylaxis, have been reported with the use of clostridium histolyticum collagenase. If such a reaction occurs, another injection of QWO should be stopped and appropriate medical treatment should be started immediately. Advise patients to seek medical attention immediately if they experience symptoms of severe hypersensitivity reactions.

Bruising at the injection site
In clinical trials, 84% of subjects treated with QWO developed bruising at the injection site. Subjects with bleeding disorders or using anticoagulants or antiplatelet agents (except those taking ≤ 150 mg aspirin per day) were excluded from participation in trials 1 and 2.

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

Substitution of collagenase products
QWO should not be replaced by other injectable collagenase products. QWO is not intended for the treatment of Peyronie’s disease or Dupuytren’s contracture.

In clinical trials, the most frequently reported adverse reactions in patients treated with an incidence of QWO ≥ 10% were at the injection site: bruising, pain, lump and pruritus.

About cellulite
Cellulitis is a localized alteration in the contour of the skin that has been reported in over 90% of post-puberty women and affects women of all races and ethnicities.1.2 The presence of cellulite is associated with changes in the thickness of the dermis and fat cells and connective tissue under the skin.3 A main factor in the cause of the disease is the collagen containing septa that attach the skin to the underlying fascia layers.4.5 The septa attach the skin which, along with additional contributory protuberances of subcutaneous fat, causes the characteristic surface dimpling of cellulite.6.7 These fibrous septa are oriented differently with varying thickness in women than in men, which informs our understanding of cellulite as a sex-related condition.8 Cellulite is clinically present on the buttocks, thighs, lower abdomen and arms.

We know that cellulite is different from generalized obesity.9 In generalized obesity, the fat cells undergo hypertrophy and hyperplasia that are not limited to the pelvis, thighs and abdomen.2 In areas of cellulite, the characteristic large adipocytes, metabolically stable, have physiological and biochemical properties that differ from adipose tissue elsewhere.ten An anatomical study done in 2019 found that women had a higher fat lobule height than men, which may also contribute to the mattress-like appearance due to the tension of the fibrous partitions.8.10 Weight gain can make cellulite more noticeable, but cellulite can be present even in thin people.9
