Ibrutinib may prove useful for patients whose chronic lymphocytic leukemia (CLL) relapses after allogeneic stem cell transplantation, Dr. C. S. Link and colleagues reported.
Ibrutinib has shown efficacy in patients with high-risk CLL, but there are few data from patients who relapsed after allogeneic stem cell transplantation, wrote Dr. Link of the Medizinische Klinik und Poliklinik I, Universitätsklinikum Carl Gustav Carus and the DFG Research Center for Regenerative Therapies, both at the Technische Universität Dresden (Germany).
The researchers performed analyses on cytokine levels and direct measuring of CD4 Th1 and CD4 Th2 cells in a study of five CLL patients treated with ibrutinib for relapse after allogeneic transplants. All patients had partial responses to ibrutinib and one had a minimal residual disease–negative remission.
At 1 year, none of the patients had relapsed; however, one patient died of pneumonia while on ibrutinib treatment. No other unexpected adverse events were observed, the researchers reported in the study, which was published online on Jan. 11.
No substantial changes in T-cell distribution in favor of a CD4 Th1 T-cell shift were noted based on flow cytometry and analyses of T cell–mediated cytokine levels. No acute exacerbations of graft-versus-host disease occurred.
