Kadmon Doses First Patient in Open-Label Phase 2 Clinical Trial of Belumosudil in Systemic Sclerosis

NEW YORK, NY / ACCESSWIRE / April 1, 2021 / Kadmon Holdings, Inc. (NASDAQ:KDMN) today announced that the first patient has been dosed in an open-label Phase 2 clinical trial of belumosudil, the Company's ROCK2 inhibitor, in patients with diffuse cutaneous systemic sclerosis (dcSSc), a chronic immune disorder characterized by fibrosis of the skin and internal organs.

The Phase 2 study (KD025-215) will enroll up to 15 adults with dcSSc who will receive orally administered belumosudil 200 mg twice daily (BID). The primary endpoint is the Combined Response Index for Systemic Sclerosis (CRISS) score. The Company plans to present initial data from this study by year-end 2021.

In addition to the KD025-215 trial, an ongoing, double-blind, placebo-controlled Phase 2 clinical trial of belumosudil (KD025-209) is currently enrolling 60 adults with dcSSc. Patients are randomized to receive belumosudil 200 mg once daily (QD), belumosudil 200 mg BID or placebo.

"As we await the results of our placebo-controlled study, we are pleased to concurrently initiate the open-label trial of belumosudil in systemic sclerosis, as its mechanism represents a promising therapeutic approach for this difficult-to-treat disease," said Harlan W. Waksal, M.D., President and CEO of Kadmon. "We are encouraged by the robust responses achieved across all organ systems in clinical trials of belumosudil in cGVHD, which shares mechanistic and pathophysiologic similarities to systemic sclerosis. We look forward to receiving initial data from this trial later this year."

The U.S. Food and Drug Administration (FDA) has granted Orphan Drug Designation to belumosudil for the treatment of systemic sclerosis.
