Manifestations of cGVHD

The inflammatory and fibrotic manifestations of cGVHD have widespread clinical impacts

Patients who undergo an alloHCT can develop complications, such as debilitating and life-threatening cGVHD.1-3 In fact, cGVHD is the leading cause of nonrelapse mortality in patients surviving >2 years post alloHCT.3

Risk factors for identifying patients who are more likely to develop cGVHD4-7

  • Prior aGVHD
  • Use of ATG
  • Older age
  • Bone marrow source
  • RIC
  • HLA mismatch
  • Female donor to male recipient
  • Peripheral blood stem cell source
  • High numbers of infused T cells
  • Positive CMV serology

Multiple organs can be affected by cGVHD8

Organs affected by cGVHD at the time of diagnosis

Of patients who received 3 lines of systemic therapy, 42% had involvement of ≥4 organs at the time of diagnosis.8

According to a study of a prospectively assembled cohort of patients with cGVHD, approximately half of patients had lung manifestations.9

BOS, a severe life-threatening fibrotic manifestation of cGVHD, is difficult to treat and may be clinically underrecognized.10-13

Inflammation and fibrosis

The relationship between inflammation and fibrosis in cGVHD is complex and not fully understood.14,15 However, there is an association between chronic inflammatory changes in cGVHD and collagen-producing fibroblasts.16,17 This can lead to the development of fibrotic lesions across multiple organs.16,18

  • Significant morbidity and life-threatening complications are largely the result of fibrosis,19 which can affect extensive areas of the skin20 and involve other organs, such as the lungs15,18
  • Although some aspects of inflammation in cGVHD can be addressed, there is limited evidence regarding the effectiveness of current treatments on fibrosis21-26

REZUROCK is designed to restore immune homeostasis and to downregulate the fibrotic processes of cGVHD.27-29

Patients routinely require multiple lines of systemic therapy to address the ongoing burden of cGVHD

A prospective, multicenter, observational study, which included 250 adult patients who underwent an alloHCT and subsequently received treatment for cGVHD, demonstrated that30

  • Patients received a median of 3 lines of systemic therapy, and the median time to permanent discontinuation of IST was 69 months
  • Progressive disease or lack of improvement was the reason 86% of patients required the initiation of new treatments, indicating a lack of cGVHD control with previous lines of systemic therapy
  • More than half of patients who discontinued IST at least 1 time had to restart IST within a median of 3.4 months
  • Of the patients attempting a first-time discontinuation of IST, 23% did so only after
    3 lines of systemic therapy

of patients progress
beyond 2 lines of systemic therapy, emphasizing a clear unmet need in treatment.30

REZUROCK is an effective and innovative

dual inhibitor

for the treatment of cGVHD.27-29

Indication

REZUROCKTM (belumosudil) is indicated for the treatment of adult and pediatric patients 12 years and older with chronic graft-versus-host disease (chronic GVHD) after failure of at least two prior lines of systemic therapy.

IMPORTANT SAFETY INFORMATION

Warnings and Precautions

Embryo-Fetal Toxicity: Based on findings in animals and its mechanism of action, REZUROCK can cause fetal harm when administered to a pregnant woman. Advise pregnant women of the potential risk to a fetus. Advise females of reproductive potential and males with female partners of reproductive potential to use effective contraception during treatment with REZUROCK and for at least one week after the last dose

Adverse Reactions

The most common (≥ 20%) adverse reactions, including laboratory abnormalities, were infections, asthenia, nausea, diarrhea, dyspnea, cough, edema, hemorrhage, abdominal pain, musculoskeletal pain, headache, phosphate decreased, gamma glutamyl transferase increased, lymphocytes decreased, and hypertension

Permanent discontinuation of REZUROCK due to adverse reactions occurred in 18% of patients. The adverse reactions which resulted in permanent discontinuation of REZUROCK in > 3% of patients included nausea (4%). Adverse reactions leading to dose interruption occurred in 29% of patients. The adverse reactions leading to dose interruption in ≥ 2% were infections (11%), diarrhea (4%), and asthenia, dyspnea, hemorrhage, hypotension, liver function test abnormal, nausea, pyrexia, edema, and renal failure with (2% each)

Monitor total bilirubin, aspartate aminotransferase (AST), and alanine aminotransferase (ALT) at least monthly

Drug Interactions

Strong CYP3A Inducers: Coadministration of REZUROCK with strong CYP3A inducers decreases belumosudil exposure, which may reduce the efficacy of REZUROCK. Increase the dosage of REZUROCK to 200 mg twice daily when coadministered with strong CYP3A inducers

Proton Pump Inhibitors: Coadministration of REZUROCK with proton pump inhibitors decreases belumosudil exposure, which may reduce the efficacy of REZUROCK. Increase the dosage of REZUROCK to 200 mg twice daily when coadministered with proton pump inhibitors

Use in Specific Populations

Pregnancy: Based on findings from animal studies and the mechanism of action, REZUROCK can cause fetal harm when administered to pregnant women. There are no available human data on REZUROCK use in pregnant women to evaluate for a drug-associated risk. Advise pregnant women and females of reproductive potential of the potential risk to the fetus

Lactation: There are no data available on the presence of belumosudil or its metabolites in human milk or the effects on the breastfed child, or milk production. Because of the potential for serious adverse reactions from belumosudil in the breastfed child, advise lactating women not to breastfeed during treatment with REZUROCK and for at least one week after the last dose

Pediatric Use: The safety and effectiveness of REZUROCK have been established in pediatric patients 12 years and older. The safety and effectiveness of REZUROCK in pediatric patients less than 12 years old have not been established

Geriatric Use: Of the 186 patients with chronic GVHD in clinical studies of REZUROCK, 26% were 65 years and older. No clinically meaningful differences in safety or effectiveness of REZUROCK were observed in comparison to younger patients

Renal and Hepatic Impairment: Treatment with REZUROCK has not been studied in patients with pre-existing severe renal or hepatic impairment. For patients with pre-existing severe renal or hepatic impairment, consider the risks and potential benefits before initiating treatment with REZUROCK
