DUBLIN, Ireland I September 6, 2019 I Endo International plc (NASDAQ: ENDP) announced today that the Company has submitted a Biologics License Application (BLA) to the U.S. Food and Drug Administration (FDA) for collagenase clostridium histolyticum (CCH) for the treatment of cellulite in the buttocks. The submission is based on positive results from two identical Phase 3 RELEASE* studies that were were presented at the 2019 Annual Meeting of the American Academy of Dermatology (AAD) in Washington, DC and subsequently at the The Aesthetic Meeting 2019 in New Orleans, LA.
The RELEASE-1 and RELEASE-2 Phase 3 studies, which were identically designed, randomized, double blinded and placebo-controlled, assessed the efficacy and safety of CCH for the treatment of cellulite in women. A greater percentage of the 843 women treated during the studies (CCH vs. placebo: RELEASE 1, n=210 vs n=213; RELEASE-2, n=214 vs n=206) met the primary endpoint of response with CCH versus placebo in both the RELEASE-1 (P=0.006) and RELEASE-2 (P=0.002) studies.
In addition, statistically significant improvements with CCH versus placebo were observed for 8 of 8 (RELEASE-1) and 7 of 8 (RELEASE-2) secondary endpoints. All patient-centric endpoints, evaluated using validated patient-reported scales like Patient Reported Photonumeric Cellulite Severity Scale (PR-PCSS), Subject Global Aesthetic Improvement Scale (S-GAIS), Patient Reported Cellulite Impact Score (PR-CIS) and Subject Self Rating Scale (SSRS), showed statistically significant improvement in the CCH group when compared to the placebo group. Most adverse events observed in CCH-treated patients were transient, mild/moderate and injection-site related (e.g., bruising, pain, induration, pruritus, erythema, and discoloration).
The FDA has a 60-day filing review period to determine whether the BLA is complete and acceptable for filing. Endo will communicate the FDA's decision.
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.1,2 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.2,3 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.4 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.5
