IL2RA and T-cell non-Hodgkin lymphoma: Due to the previous results indicating that an elevated level of CD25 correlates with chemotherapy resistance and that CD25-mediated resistance can be reversed by targeting CD25, in the phase-II study, a combination of chemotherapeutic pegaspargase and basiliximab is being investigated in the treatment of relapsed or refractory NK and T cell lymphomas (NCT04337593).
