DUBLIN, Nov. 19, 2019 /PRNewswire/ -- Endo International plc (NASDAQ: ENDP) announced today that the U.S. Food and Drug Administration (FDA) has accepted for review the original Biologics License Application (BLA) for collagenase clostridium histolyticum (CCH) for the treatment of cellulite in the buttocks. The Prescription Drug User Fee Act (PDUFA), or target action date for the BLA, has been set for July 6, 2020.

"We have confidence in and are excited by the promising results of our CCH for cellulite program, which encompasses the largest U.S. clinical trials for the treatment of cellulite in history¹," said Paul Campanelli, Endo's Chairman, President and Chief Executive Officer. "Acceptance of our BLA is a significant milestone and we look forward to advancing the next steps to bring this treatment to aesthetic physicians and their patients."

The BLA is supported by the results of the RELEASE*-1 and RELEASE-2 Phase 3 studies, as well as a robust clinical and pre-clinical program.

About Cellulite

Cellulite is a localized alteration in the contour of the skin that has been reported in 85 to 98 percent of post-pubertal females and affects women of all races and ethnicities.^2,3 The primary cause of the condition is a thickening of the collagen septae that attach the skin to the underlying fascia layers with additional contributing protrusions of subcutaneous fat. The septae tether the skin, which causes the surface dimpling characteristic of cellulite.^3,4 Cellulite clinically presents on the buttocks, thighs, lower abdomen and arms.

It is known that cellulite is different from generalized obesity. In generalized obesity, adipocytes undergo hypertrophy and hyperplasia that are not limited to the pelvis, thighs, and abdomen.⁵ In areas of cellulite, characteristic large, metabolically stable adipocytes have physiologic and biochemical properties that differ from adipose tissue located elsewhere. Weight gain makes cellulite more noticeable, but it may be present even in thin subjects. Genetics may also play a role, since cellulite tends to run in families.

Despite multiple therapeutic approaches for the attempted treatment of patients with cellulite, there are currently no FDA-approved injectable treatments on the market.⁶
