Could fewer chemo rounds be enough for follicular lymphoma?
NCT ID NCT05058404
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This phase 3 trial compares a shorter chemotherapy regimen (4 cycles) against the standard 6 cycles, both combined with immunotherapy, for people with newly diagnosed, high-tumor-burden follicular lymphoma. The goal is to see if the shorter treatment is just as effective at keeping the cancer from progressing. About 605 participants are being studied across multiple centers in Italy.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Rituximab and bendamustine (immunochemotherapy)
- What this could lead to
- If successful, this could mean many patients with follicular lymphoma can receive fewer chemotherapy cycles without compromising disease control, reducing side effects.
- What could go wrong
- This is an early-stage phase 3 trial, and the shortened regimen may prove less effective in preventing cancer progression. Results may not apply to all patients.

Inclusion Criteria: 1. Histologically documented diagnosis of CD20+ Follicular lymphoma grade 1-2 or 3a, as defined in the 2017 edition of the World Health Organization (WHO) classification; 2. Age ≥ 18 years; 3. Eastern Cooperative Oncology Group (ECOG) performance status 0-2 (Appendix B); 4. No previous immunochemotherapy for the lymphoma (localized radiotherapy or rituximab monotherapy with max of 4 doses are allowed); 5. Ann Arbor stage II-IV (Appendix A); 6. High tumor burden as per Groupe d'Etude des Lymphomes Folliculaires (GELF) criteria defined as the presence of at least one of the following: * systemic symptoms; * Tumor bulk (any nodal or extranodal tumor mass with diameter \> 7 cm); * involvement of ≥ 3 nodal sites, each with a diameter ≥ 3 cm; * splenomegaly; * compressive syndrome (organ compression); * serous effusion; * circulant malignant cells; * cytopenia; * Eastern Cooperative Oncology Group - Performance Status (ECOG-PS) \> 1; * Lactate dehydrogenase (LDH) \> upper limit of normality (ULN); * β2-microglobulin \> 3 mg/L. 7. At least one site of measurable nodal disease at baseline ≥ 1.5 cm in the longest transverse diameter as determined by CT scan (MRI is allowed if CT scan cannot be performed); or evaluable disease at baseline FDG-PET (18F-fluorodeoxyglucose (FDG)-Positron Emission Tomography (PET)) scan (at least one metabolic active site of disease); 8. Adequate hematological counts (unless due to bone marrow involvement by lymphoma) defined as follows: 1. Absolute Neutrophil count (ANC) \> 1.5 x 109/L; 2. Platelet count ≥ 80 x 109/L ; 3. Hemoglobin ≥ 10 g/dL. 9. Adequate renal function defined as creatinine ≤ 2 mg/dL, unless secondary to lymphoma; 10. Adequate hepatic function defined as bilirubin ≤ 2 mg/dL, unless secondary to lymphoma; 11. Left Ventricular Ejection Fraction (LVEF) \> 50% at bidimensional echocardiogram (mandatory only for patients receiving R/G-CHOP); 12. Life expectancy ≥ 6 months; 13. Subject understands and voluntarily signs an informed consent form approved by an Independent Ethics Committee (IEC) prior to the initiation of any screening or study-specific procedures; 14. Subject must be able to adhere to the study visit schedule and other protocol requirements; 15. Women of childbearing potential (WOCBP) and men must agree to use effective contraception if sexually active. This applies for the time period between signing of the informed consent form and 12 months after last rituximab dose or 18 months after last obinutuzumab dose. A woman is considered of childbearing potential, i.e. fertile, following menarche and until becoming postmenopausal unless permanently sterile. Permanent sterilization methods include but are not limited to hysterectomy, bilateral salpingectomy and bilateral oophorectomy. A postmenopausal state is defined as no menses for continuous 12 months without an alternative medical cause. A high follicle stimulating hormone (FSH) level in the postmenopausal range may be used to confirm a postmenopausal state in women not using hormonal contraception or hormonal replacement therapy. The investigator or a designated associate is requested to advise the patient how to achieve highly effective birth control (failure rate of less than 1%) e.g., intrauterine device (IUD), intrauterine hormone-releasing system (IUS), bilateral tubal occlusion, vasectomized partner. The use of condoms by male patients is required (even if surgically sterilized, i.e., status post vasectomy) unless the female partner is permanently sterile. Full sexual abstinence is admitted when this is in line with the preferred and usual lifestyle of the subject, for the same time period planned for other methods of birth control (see above). Periodic abstinence (e.g., calendar, ovulation, symptothermal, post ovulation methods for the female partner) and withdrawal are not acceptable methods of contraception). Exclusion Criteria: 1. Histological diagnosis different from FL grade 1-3a WHO 2017 classification; 2. Suspect or clinical evidence of Central Nervous System (CNS) involvement by lymphoma; 3. Contraindication to the use of anti-CD20 monoclonal antibodies; 4. Subject has received any anticancer therapy (chemotherapy, immunotherapy, investigational therapy, including targeted small molecule agents) within 14 days prior to the first dose of study drug; 5. Noteworthy history of neurologic, psychiatric, endocrinological, metabolic, immunologic, or hepatic disease that would preclude participation in the study or compromise ability to give informed consent; 6. Any history of other active malignancies within 3 years prior to study entry, with the exception of: adequately treated in situ carcinoma of the cervix uterine; basal cell carcinoma of the skin or localized squamous cell carcinoma of the skin; limited stage surgically removed breast cancer or adequately treated with radiation therapy; limited stage prostate carcinoma surgically removed or adequately treated with radiation therapy; previous malignancy confined and surgically resected with curative intent; 7. Evidence of other clinically significant uncontrolled condition(s) including, but not limited to: * Uncontrolled and/or active systemic infection (viral, bacterial or fungal), including active ongoing infection from SARS-CoV-2; * Chronic or acute hepatitis B (HBV) or hepatitis C (HCV) requiring treatment. Note: subjects with serologic evidence of prior vaccination to HBV (i.e., HBsAg negative, HBsAb positive and HBcAb negative) or positive HBcAb from previous infection or intravenous immunoglobulins (IVIG) may participate; inactive carriers (HBsAg positive with undetectable HBV- DNA) are eligible. Patients with presence of HCV antibody are eligible only if Polymerase Chain Reaction (PCR) negative for HCV-RNA; 8. Women who are pregnant or breastfeeding.
