What is the purpose of this trial?

This trial explores a new treatment option for individuals with moderate to severe chronic graft versus host disease (cGVHD), a condition that can occur after a stem cell transplant. The study compares the effects of the drug belumosudil (also known as Rezurock, Rholistiq, KD025, or SLx-2119) with a placebo to determine its effectiveness in managing symptoms when combined with standard corticosteroids. Participants should have recently been diagnosed with cGVHD following a stem cell transplant and should not have received systemic treatments for this condition. The trial aims to find better ways to control cGVHD and improve patients' quality of life. As a Phase 3 trial, it represents the final step before potential FDA approval, offering participants a chance to contribute to a treatment that could soon become widely available.

Will I have to stop taking my current medications?

The trial does not specify if you need to stop taking your current medications. However, if you are on other immunosuppressive agents for acute GVHD, the dose must be below a certain level. It's best to discuss your specific medications with the study team.

Is there any evidence suggesting that this trial's treatments are likely to be safe?

Research has shown that belumosudil is generally well-tolerated by people with chronic graft-versus-host disease (cGVHD). Studies have found that patients taking belumosudil did not experience severe or unexpected side effects. The treatment is considered safe for long-term use, with some patients experiencing long-lasting positive responses.

In earlier studies, most people tolerated the drug well, even those also taking other medications that weaken the immune system. No reports of serious side effects raised concerns about its safety. This suggests that belumosudil could be a safe option for those seeking new treatments for cGVHD. ^{1 2 3 4 5}

Why do researchers think this study treatment might be promising for chronic GVHD?

Researchers are excited about belumosudil for chronic graft versus host disease (cGVHD) because it offers a unique mechanism of action compared to standard treatments like corticosteroids. While most treatments for cGVHD focus on suppressing the immune response broadly, belumosudil specifically targets the Rho-associated coiled-coil containing protein kinase 2 (ROCK2) pathway. This targeted approach may help modulate the immune system more precisely, potentially reducing side effects and improving outcomes for patients. Additionally, the convenience of oral administration once daily makes it a patient-friendly option.

What evidence suggests that this trial's treatments could be effective for chronic GVHD?

Research has shown that Belumosudil, which participants in this trial may receive, offers promising results for treating chronic graft-versus-host disease (cGVHD). Studies indicate that Belumosudil achieves high success rates in treatment and improves survival outcomes for patients with cGVHD. It outperforms the best available treatments, even for those who have tried other options. Additionally, Belumosudil reduces inflammation and improves symptoms by lowering harmful proteins in the body. These findings suggest that Belumosudil could effectively manage cGVHD symptoms and enhance patient health. ^{2 6 7 8 9}

Are You a Good Fit for This Trial?

This trial is for people at least 12 years old with a body weight of ≥40kg who have moderate to severe chronic Graft Versus Host Disease (cGVHD) after an allogeneic HCT. They must need systemic corticosteroid treatment and not have had prior cGVHD treatments, except possibly corticosteroids within the last 7 days. Participants should be able to consent and follow contraception guidelines.

What Are the Treatments Tested in This Trial?

Interventions

• Belumosudil
• Placebo
• Prednisolone
• Prednisone

Trial Overview The study tests Belumosudil combined with corticosteroids against a placebo plus corticosteroids in treating newly diagnosed cGVHD. It's a Phase 3 trial where participants are randomly assigned to one of two groups and treated until their condition progresses or they experience unacceptable side effects.

How Is the Trial Designed?

Group I: Belumosudil Experimental Treatment 3 Interventions

Participants will receive belumosudil 200 mg tablets per os(PO) once daily (QD) per 28-day cycles starting on Day 1 until discontinuation criteria are met or until end of study Note: 200mg two times a day (BID) is used in some cases, when the subject is taking a proton pump inhibitor or a strong CYP3A4 inducer)

Group II: Placebo Placebo Group 3 Interventions

Participants will receive matching placebo tablets PO QD per 28-day cycles starting on Day 1 until discontinuation criteria are met or until end of study

Belumosudil is already approved in United States, Canada for the following indications:

Published Research Related to This Trial

Belumosudil, an oral medication targeting ROCK2, showed a high overall response rate of 74% for the 200 mg daily dose and 77% for the 200 mg twice daily dose in patients with chronic graft-versus-host disease (cGVHD) after multiple prior treatments, indicating its efficacy in this challenging condition.

The treatment was well tolerated, with a median duration of response of 54 weeks and significant symptom reduction in 59% to 62% of subjects, while adverse events were consistent with those expected in cGVHD patients, suggesting a favorable safety profile.

Ibrutinib, belumosudil, and ruxolitinib have been recently approved by the FDA as effective treatments for chronic graft-versus-host disease (cGVHD), a serious complication following allogeneic hematopoietic cell transplantation.

These new therapies offer alternative mechanisms of action compared to traditional glucocorticoids, potentially reducing the severe side effects associated with long-term steroid use in cGVHD patients.

In a multicenter trial involving 138 patients with chronic graft-versus-host disease, the combination of prednisone and sirolimus showed similar effectiveness to the traditional treatment that includes a calcineurin-inhibitor, with no significant differences in response rates after 6 months or 2 years.

The prednisone/sirolimus treatment resulted in fewer kidney-related side effects and better physical functioning scores compared to the calcineurin-inhibitor group, suggesting it may be a safer and more tolerable option for patients.

In a study of 50 patients with oral symptoms of chronic graft-versus-host disease (cGVHD), topical budesonide showed a greater reduction in cGVHD examination scores compared to dexamethasone after one month, indicating it may be more effective for this condition.

Both treatments significantly reduced oral pain severity, but while budesonide had a higher overall treatment response rate (53.8%) compared to dexamethasone (29.2%), the difference was not statistically significant.

In a study of 164 patients with chronic graft-v-host disease (GVHD), treatment with prednisone alone resulted in better survival rates and fewer infections compared to the combination of prednisone and azathioprine, particularly in standard-risk patients.

However, patients with thrombocytopenia (low platelet counts) showed poorer outcomes with prednisone alone, indicating that alternative treatment strategies are needed for high-risk patients.
