Phase III Trial Comparing Radiotherapy Alone or With Obinutuzumab for Early Stage Follicular Lymphoma

What this Trial Is About

Researchers are conducting a phase III randomized clinical trial to study early stage Follicular Lymphoma, a type of lymphoma that has not been treated before. The trial compares the effects of local Radiotherapy alone versus Radiotherapy combined with the drug Obinutuzumab. The goal is to better understand how these treatments work for patients with early stage Follicular Lymphoma and to evaluate progression-free survival and other outcomes. Participants will be randomly assigned to one of two groups one group will receive involved-site Radiotherapy at a standard dose of 24Gy alone the other group will receive the same Radiotherapy followed by Obinutuzumab infusionsfour weekly doses plus four additional doses every three weeks, totaling eight doses. This open-label study is conducted across multiple centers. During the study, participants will be monitored for treatment response and side effects over a period of up to 45 months, including 9 months of treatment and 36 months of follow-up. Assessments include imaging scans, laboratory tests, and molecular analyses to evaluate response rates, disease progression, and molecular markers. Safety and adverse events will be tracked throughout, with long-term follow-up to understand treatment effects and disease status.
