What is the therapeutic scope of Belumosudil tablets and what are its indications?

Belumosudil mesylate tablets (Belumosudil), as a kinase inhibitor, are mainly used to treat chronic graft-versus-host disease (GVHD). GVHD is a common post-transplant complication that occurs in patients undergoing hematopoietic stem cell transplantation. The pathogenesis of GVHD is closely related to the recipient's immune system's attack response to the donor's immune cells in the transplant, which in turn causes the immune system to attack the recipient's normal tissues, especially organs such as the skin, liver, and gastrointestinal tract.

For the treatment ofGVHD, traditional treatments include glucocorticoids and other immunosuppressive drugs, such as cyclosporine, tacrolimus, etc. Although these drugs can effectively suppress immune responses, long-term use may cause serious side effects and have limited efficacy in some patients. Therefore, as a new type of therapeutic drug, besudil's main indication is to treat patients with chronic GVHD who have insufficient response to traditional treatments.

The mechanism of action of Besudil is mainly to reduce the overactivity of the immune system by inhibiting kinases related to immune response. Specifically, Besudil inhibits certain kinases such asRho-kinase, thereby interfering with the proliferation and activation of T cells and reducing immune-mediated inflammatory responses. Therefore, besudil can effectively relieve the symptoms of GVHD patients and improve their quality of life.

Besudil is an oral medication indicated for use in patients 12 years of age and older with chronic GVHD, especially those who cannot be effectively controlled by glucocorticoids or other traditional systemic treatments. In clinical application, besudil is usually used as a second-line treatment drug and has been approved by the US FDA and other national regulatory agencies for the treatment of chronic GVHD.

In addition, clinical studies of besudil are ongoing to explore its potential in other immune-mediated diseases, such as other types of immune-related diseases and allergic diseases. Therefore, Besudil may expand its indications in the future to provide treatment options for more patients.
