A Study Comparing Obinutuzumab and BGB-3111 Versus Obinutuzumab Alone in Treating R/R Follicular Lymphoma (ROSEWOOD)

January 30, 2026 updated by: BeiGene

An International, Phase 2, Open-Label, Randomized Study of BGB-3111 Combined With Obinutuzumab Compared With Obinutuzumab Monotherapy in Relapsed/ Refractory Follicular Lymphoma

This clinical study examined the safety and efficacy of the combination of zanubrutinib and obinutuzumab versus obinutuzumab alone in adults with follicular lymphoma whose disease returned after or did not respond to prior therapy.

Study Overview

Detailed Description

This study randomly assigned participants in a 2:1 ratio to receive either zanubrutinib plus obinutuzumab or obinutuzumab alone. The assignment considered how many prior treatments participants had received, whether their cancer had stopped responding to rituximab, and whether they were enrolled in Mainland China or other regions. Each treatment cycle lasted 28 days, with zanubrutinib taken by mouth twice daily and obinutuzumab given intravenously on a set schedule, followed by optional maintenance for up to 24 months. Participants who had obinutuzumab alone could have switched to the combination treatment if their disease worsened or did not respond after 12 months, if confirmed by an independent review.

Change From Baseline in European Organization for Research and Treatment of Cancer (EORTC) Quality of Life Questionnaire-Core 30 (QLQ-C30) Global Health Status (GHS)/Quality of Life (QOL), Physical Functioning, Role Functioning, and Symptom Scores
Time Frame: Baseline, Week 12, and Week 24
The EORTC QLQ-C30 includes 30 questions covering 5 functional scales (physical, role, emotional, cognitive, social), 1 global health scale, 3 symptom scales (fatigue, nausea/vomiting, pain), and 6 single items (dyspnea, insomnia, appetite loss, constipation, diarrhea, financial difficulties). Participants report their health over the past week. Most items use a 4-point scale (1 = Not at all to 4 = Very much), while 2 global QOL items use a 7-point scale (1 = Very poor to 7 = Excellent). Raw scores are linearly transformed to a 0-100 scale; higher GHS and functional scores and lower symptom scores indicate better quality of life.
Baseline, Week 12, and Week 24
Change From Baseline in European Quality of Life 5-Dimensions, 5-level (EQ-5D-5L) Visual Analogue Scale (VAS)
Time Frame: Baseline, Week 12, and Week 24
The EQ-5D-5L measures health outcomes using a VAS to record a participant's self-rated health on a scale from 0 to 100, where 100 is 'the best health you can imagine' and 0 is 'the worst health you can imagine.' A higher score indicates better health outcomes.
Baseline, Week 12, and Week 24
Number of Participants Experiencing Treatment-Emergent Adverse Events (TEAEs) and Serious Adverse Events (SAEs)
Time Frame: From first dose to 30 days after zanubrutinib, 90 days after obinutuzumab, or before new therapy, whichever came first, up to study cut-off (31 Dec 2024); maximum exposure was 28.7 months for obinutuzumab and 67.4 months for combination therapy.
An adverse event refers to any unintended or unfavorable sign, symptom, or condition (including abnormal lab results) that occurs during the study, regardless of whether it is linked to the study drug.
From first dose to 30 days after zanubrutinib, 90 days after obinutuzumab, or before new therapy, whichever came first, up to study cut-off (31 Dec 2024); maximum exposure was 28.7 months for obinutuzumab and 67.4 months for combination therapy.

IPD Plan Description

BeiGene shares data on completed studies responsibly and provides qualified scientific and medical researchers access to data and supporting documentation for clinical trials in dossiers for medicines and indications after submission and approval in the United States, China, and Europe. Clinical trials supporting subsequent local approvals, new indications, or combination products are eligible for sharing once corresponding regulatory approvals are achieved.

BeiGene shares data only when permitted by applicable data privacy and security laws and regulations, when it is feasible to do so without compromising the privacy of study participants, and other considerations.

Qualified researchers with appropriate competencies who are engaged in novel scientific research may submit a request for participant-level data with a research proposal for BeiGene review. Research teams must include a biostatistician and sign a Data Sharing Agreement prior to receiving access to clinical trial data.
