First-line treatment of FL:
What do we know now?
 Immunochemotherapy is the new standard as up-front
therapy in follicular lymphoma1
– R-CHOP vs R-CVP improves CR rate and PFS2,3,4
– Fludarabine-containing regimens are as effectives as
R-CHOP but more toxics3,4
– R-Benda vs R-CHOP improves CR rate and PFS5
 Maintenance therapy with Rituximab improves PFS3 and
reduces the risk of death (meta-analysis)6

Stage 1 identified a flat dose of 1,400 mg Rituximab SC for non-inferiority testing

Stage 2 primary endpoint: Non-inferiority of Ctrough in patients receiving Rituximab
subcutaneously compared with by IV infusion
-
•
Protocol-specified non-inferiority limit was an SC:IV Ctrough ratio of 0.8
Secondary endpoints included: PK (area under the curve [AUC]) and safety

SC administration of Rituximab compared with IV
administration as maintenance therapy in
patients with FL: the SPARKTHERA study
 Primary PK endpoint (SC:IV Ctrough ratio) was met
– Lower limits of two-sided 90% CI exceeded the non-inferiority
threshold (0.8) for q2mo (1.02) and q3mo (0.86) regimens
– Secondary PK endpoint (SC:IV AUC ratio > 0.8) was met
