NEW YORK, NY / ACCESSWIRE / December 6, 2020 / Kadmon Holdings, Inc. (Nasdaq:KDMN) today announced 12-month data from ROCKstar, its ongoing pivotal trial of belumosudil for the treatment of patients with chronic graft-versus-host disease (cGVHD), in an oral session at the 62nd American Society of Hematology (ASH) Annual Meeting.
At the 12-month follow-up analysis, belumosudil achieved clinically meaningful and statistically significant Overall Response Rates (ORRs) of 73% with 200 mg once daily (QD) (95% Confidence Interval (CI): 60%, 83%; p<0.0001) and 77% with 200 mg twice daily (BID) (95% CI: 65%, 87%; p<0.0001) in patients with cGVHD who have received at least two prior lines of systemic therapy. Responses were achieved across key patient subgroups and complete responses were observed in all organ systems, including in lung.
Belumosudil performed well across all secondary endpoints:
- Responses were durable, with a median duration of response of 50 weeks; 60% of responders have maintained their responses for 20 weeks or longer
- A Failure-Free Survival (FFS) rate of 58% was maintained at 12 months
- Clinically meaningful improvement from baseline in the Lee Symptom Scale (LSS) score, a quality-of-life measurement, was observed in 60% of patients
- 64% of patients were able to reduce their corticosteroid dose, with 21% of patients completely discontinuing corticosteroid therapy
- Belumosudil has been well tolerated and adverse events have been consistent with those expected in the cGVHD patient population
“The positive results achieved with belumosudil have continually demonstrated its ability to meaningfully address the broad spectrum of cGVHD manifestations, including difficult-to-treat organs like lung,” said Corey Cutler, MD, MPH, FRCPC, Dana-Farber Cancer Institute. “If we were to translate this data to a real-world setting, with two-thirds of patients able to reduce corticosteroid doses and achieve 50-week median duration of responses, belumosudil, if approved, would potentially offer benefit to the thousands of patients currently living with cGVHD.”
“We are extremely pleased with the 12-month results from this trial, as the Overall Response Rates have consistently strengthened, the durability has proven to be robust, the drug continues to perform across a number of key secondary endpoints and has been well tolerated,” said Harlan W. Waksal, M.D., President and CEO at Kadmon. “With the FDA’s recent acceptance of our NDA filing and a PDUFA date of May 30, 2021, we are moving forward with our commercial preparation efforts, having hired two-thirds of our planned field force. We look forward to continuing to work closely with the FDA as they complete their review of belumosudil in cGVHD.”

About ROCKstar
ROCKstar (KD025-213) is an ongoing open-label trial of belumosudil in patients with cGVHD who have received at least two prior lines of systemic therapy. Patients were randomized to receive belumosudil 200 mg once daily or 200 mg twice daily, enrolling 66 patients per arm. The primary endpoint of the study is Overall Response Rate (ORR). The ORR endpoint was met at the interim analysis, conducted two months after completion of enrollment. At the study’s follow-up analysis, conducted twelve months after completion of enrollment, belumosudil achieved ORRs of 73% and 77% in the respective arms. Belumosudil has been well tolerated and adverse events have been consistent with those expected in the patient population.
About Belumosudil
Belumosudil (KD025) is a selective oral inhibitor of Rho-associated coiled-coil kinase 2 (ROCK2), a signaling pathway that modulates inflammatory response and pro-fibrotic processes. In November 2020, the U.S. Food and Drug Administration (FDA) accepted the NDA for belumosudil for the treatment of patients with cGVHD. The FDA granted Priority Review for the NDA for belumosudil and assigned a Prescription Drug User Fee Act (PDUFA) target action date of May 30, 2021. The NDA is being reviewed under the FDA’s Real-Time Oncology Review (RTOR) and Project Orbis pilot programs. The FDA has granted Breakthrough Therapy Designation to belumosudil for the treatment of patients with cGVHD after failure of two or more lines of systemic therapy as well as Orphan Drug Designation to belumosudil for the treatment of cGVHD.
About cGVHD
cGVHD is a common and often fatal complication following hematopoietic stem cell transplantation. In cGVHD, transplanted immune cells (graft) attack the patient’s cells (host), leading to inflammation and fibrosis in multiple tissues, including skin, mouth, eye, joints, liver, lung, esophagus and gastrointestinal tract. Approximately 14,000 patients in the United States are currently living with cGVHD.
