Phase I study of selinexor in combination with dexamethasone, ifosfamide, carboplatin, etoposide chemotherapy in patients with relapsed or refractory peripheral T-cell or natural-killer/T-cell lymphoma.

Selinexor is a selective inhibitor of nuclear export with anti-cancer properties. We performed a phase I study to determine the safety and maximum tolerated dose (MTD) of selinexor when combined with high-dose dexamethasone, ifosfamide, carboplatin and etoposide (DICE) in relapsed/refractory (R/R) T-cell lymphoma (TCL) and natural-killer/T-cell lymphoma (NKTL). Patients with R/R TCL and NKTL were treated with standard dose ICE, dexamethasone 20mg on days 3 to 7, and escalating doses of oral selinexor on days 3, 5 and 7 in a 3+3 design.
