Gazyvaro and Low Dose Radiotherapy in Early Stage Follicular Lymphoma

Summary

Combined modality approach using Obitunuzumab and involved site low dose irradiation in early stage nodal follicular lymphoma. Radiation dose will be adapted for low-responders. Primary Objective: Evaluation of the rate of metabolic CR after low-dose involved site radiotherapy in combination with Gazyvaro (Obinutuzumab) in early stage nodal follicular lymphoma in order to avoid conventional full dose IF radiotherapy. Secondary Objective: Efficacy and safety of a response adapted radiation dose treatment schedule.
