Endo Provides Top-Line Results from Phase 2 Study of Collagenase Clostridium Histolyticum (CCH) in Participants With Plantar Fibromatosis

DUBLIN, March 13, 2023 /PRNewswire/ — Endo International plc (OTC: ENDPQ) today announced top-line results from its Phase 2 clinical study of collagenase clostridium histolyticum (CCH) in participants with plantar fibromatosis. While the primary endpoint when analyzed with the overall study population did not meet statistical significance, a large patient sub-population showed statistically significant improvement. The primary endpoint was improvement from baseline in the Foot Function Index (FFI) Pain Scale score when compared to those receiving placebo.

The overall clinical study population met some key secondary and exploratory endpoints, including the investigator assessment of improvement (Clinician Global Impression of Change), nodule hardness and improvement in nodule consistency. The large patient sub-population met the primary endpoint, as well as the majority of all secondary and exploratory endpoints.

The CCH safety profile in the Phase 2 clinical study was consistent with the known CCH safety profile from other studies. Most adverse events were rated as mild to moderate and there were no treatment-related serious adverse events.

“We believe we have a clear path forward to Phase 3 development for CCH in patients with plantar fibromatosis,” said James P. Tursi, M.D., Executive Vice President, Global Research & Development at Endo. “The Phase 2 clinical study data will help us refine our Phase 3 clinical study design, and we plan to begin the pivotal program later this year. We remain committed to developing and providing nonsurgical treatments to help everyone we serve live their best lives.”

“This clinical study was designed to test multiple variables with a goal to identify an optimal path to Phase 3 development, and we were successful in doing that,” said Dr. Joseph M. Caporusso, a Texas-based podiatrist and a lead clinical investigator for the Phase 2 study. “We look forward to further investigation of CCH in patients with plantar fibromatosis with the ultimate goal of providing patients the first non-surgical treatment for this condition.”

About Phase II Clinical Trial
The double-blind, placebo-controlled Phase 2 clinical trial enrolled 176 total participants with single or multiple nodules. Participants were randomized 1:1 to receive CCH or placebo. Participants received up to two treatments, depending on nodule size, separated by a minimum of 28 days. At pre-specified timepoints, participants completed the Foot Function Index (FFI), a patient-completed questionnaire that measures the impact of certain foot disorders in terms of pain, disability and activity restriction.

The primary endpoint was the change from baseline in the FFI Pain Scale score at the day 57 visit. Additional endpoints included changes in the FFI Disability Scale score, FFI Activity Restriction Scale score and numerical pain score, as well as changes in nodule hardness and consistency.

About Plantar Fibromatosis
Plantar fibromatosis (PFI), sometimes termed “Dupuytren’s disease of the foot,” is a hyperproliferative fibrous tissue disorder resulting in the formation of nodules along the plantar fascia, the thick connective tissue that supports the arch of the foot, which is often painful. There is no cure for PFI. Symptom management options include custom insoles, topical treatments, over-the-counter pain and anti-inflammatory medications, radiation therapy and steroid injections, and ultimately, surgery may be required to remove the nodules.
