Furthermore, idelalisib treatment promoted differentiation of conventional CD4+ T cells into Th1, Th2, and Th17 subsets-a response not observed with roginolisib. In summary, roginolisib functions as an effective PI3K inhibitor on leukemic cells while preserving T-cell functions, posing it as an alternative to current PI3K inhibitors.
These findings support proof of concept for roginolisib development in hematological malignancies as a single agent or in combination with venetoclax. A clinical trial of roginolisib with venetoclax and an anti-CD20 antibody is initiating in CLL.
