An Open-Label, Single Arm Study of Obinutuzumab Short Duration Infusion in Patients With Previously Untreated Advanced Follicular Lymphoma

Study Summary

This open-label, single arm study will evaluate the safety of obinutuzumab administered as a short duration infusion (SDI; target 90-minute infusion) during cycle 2 and from cycle 2 onwards in combination with chemotherapy in participants with previously untreated advanced follicular lymphoma (FL). The study has two phases: in the first phase, participants will receive the first cycle of obinutuzumab-based chemotherapy (G-chemo) induction therapy as usual with the first three infusions of obinutuzumab (1000 mg) administered at the regular infusion rate on Day 1, 8, and 15 of cycle 1. Phase 2 starts when participants who do not experience any Grade ≥ 3 infusion related reactions during the first cycle receive their first obintuzumab infusion given at the faster infusion rate in Cycle 2. For Cycle 2, Day 1 and all other following infusions (including maintenance), obinutuzumab will be administered at a faster infusion of 90-minute SDI, as long as the participant does not experience any Grade ≥ 3 infusion related reactions. The investigator is free to choose the chemotherapy for each participant (bendamustine, CHOP \[cyclophosphamide, doxorubicin, vincristine, prednisone/prednisolone/methylprednisolone\], or CVP \[cyclophosphamide, vincristine, and prednisone/prednisolone/methylprednisolone\]). The total number of cycles of G-chemo induction therapy and the cycles length depends on the chemotherapy chosen for each participant.

Primary Outcome

IRRs were defined as all adverse events (AEs) that occurred during or within 24 hours from the end of study treatment infusion and were judged as related to infusion of study treatment components by the investigator.
