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
  • No ATG use
  • 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

Find out the difference REZUROCK can make.

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

Treatment of fibrosis in the lungs is a critical unmet need.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
