In the Phase 2 DYNAMO trial of duvelisib monotherapy for relapsed/refractory iNHL...for FL pts between high and low risk subgroups stratified by prognostic indexes...shorter mPFS was associated with higher levels of CXCL11 (9.0 moL, n=39 vs 5.6 moH, n=32) and IL2RA (9.0 moL, n=36 vs 5.6 moH, n=35)....Elevated levels of CXCL11 and IL2RA correlated with shorter mPFS.
