The NDA was reviewed under the Real-Time Oncology Review (RTOR) pilot programme and under Project Orbis. For the review, the US FDA collaborated with regulatory agencies in Australia, Canada, Switzerland and the UK [6,7].

In cGVHD, transplanted graft cells attack host cells, leading to inflammation & fibrosis. This selective oral inhibitor of Rho-associated coiled-coil kinase 2 (ROCK2), a signaling pathway that modulates inflammatory response & pro-fibrotic processes.[2,3]
The number of allogeneic bone marrow and stem cell transplants is increasing worldwide. Graft-versus-host disease (GvHD) is a serious complication of this type of transplant. The incidence of acute GvHD varies widely, ranging from 10-80% depending on risk factors [1].

Trial or other data
Apr 22
Sanofi releases pooled data from two trials of Rezurock that show a strong correlation between certain organ responses and improvements in patient-reported outcomes. The clinically meaningful changes in PROs were reported in the skin, mouth, eye, lung, upper gastrointestinal and overall measures [9].
Apr 21
Results from KD025-208, the PIIa trial of belumosudil (n=54) pts in the US with cGVHD who had received 1-3 prior lines of therapy were published in the Journal of Clinical Oncology. With an overall median follow-up of 29 months, the ORR (95% CI) with belumosudil 200 mg once daily, 200 mg twice daily, and 400 mg once daily was 65% (38% to 86%), 69% (41% to 89%), and 62% (38% to 82%), respectively. Median duration of response was 35 weeks, and improvement was noted in quality-of-life corticosteroid use. The 2-year overall survival rate was 82% (69% to 90%). Belumosudil was well-tolerated, with low rates of cytopenia. There were no unexpected adverse events and no apparent increased risk of infection, including cytomegalovirus infection and reactivation.

Pivotal open label, randomised PII ROCKstar trial (NCT03640481; KD025-213) initiated to evaluate the efficacy and safety of belumosudil (200 mg OD or 200 mg BD) in pts with cGvHD after failure of 2 or more lines of systematic therapy. Trial has a primary completion date of Sept 21. [3,4]
Sep 16
PIIa randomised, open-label, 24-week KD025-208 trial (NCT02841995) initiated looking at belumosudil safety at various dose levels (200mg-400mg OD) for the treatment of cGVHD in the US. [3]
