Abstract:
The lack of standardized criteria for measuring therapeutic response has been a major obstacle to the development of therapeutic trials in chronic graft-versus-host disease (cGvHD). Nevertheless, recent advances have been made in understanding of the biology and pathophysiology of cGvHD, as well as establishing more precise criteria for the diagnosis and classification of disease manifestations. The momentum has shifted, and currently there is a long list of new potential treatment targets being identified for cGvHD. Consequently, new drugs are being implemented for its prophylaxis and treatment. It is crucial to continue that trend and develop better systems to test new drugs in clinical practice that would eventually translate toward seeking regulatory review and approval. We provide a historical perspective and current challenges in conducting cGvHD clinical trials.
Insights
Developing effective clinical trials for chronic graft-versus-host disease (cGvHD) is hampered by a lack of standardized response criteria. Recent progress in understanding cGvHD biology and identifying new targets is paving the way for improved therapeutic strategies and drug development.
