- Complete response (CR) [ Time Frame: Up to 6 cycles ]
- Sustained complete response rate (CR30) [ Time Frame: Up to 30 months ]Defined by centrally read positron emission tomography (PET)/computed tomography (CT).
- Progression-free survival (PFS) [ Time Frame: From date of registration to date of first observation of progressive disease, or death due to any cause, assessed up to 5 years ]Will be calculated using the method of Kaplan-Meier. 95% confidence for the survival estimates will be constructed using the method of Brookmeyer-Crowley. With 31 eligible patients in each arm, progression free survival at a particular time point, and the 30-month sustained response rate can be estimated to within at least +/- 18% with 95% confidence.
- Duration of response (CR, partial response [PR]) [ Time Frame: From date of first documentation of response to treatment (CR, PR) to date of first documentation of progression, or death due to any cause, assessed up to 5 years ]Will be calculated using the method of Kaplan-Meier.
- Overall survival (OS) [ Time Frame: Up to 5 years ]Will be calculated using the method of Kaplan-Meier. 95% confidence for the survival estimates will be constructed using the method of Brookmeyer-Crowley. With 31 eligible patients in each arm, OS at a particular time point, and the 30-month sustained response rate can be estimated to within at least +/- 18% with 95% confidence.
- Incidence of adverse events [ Time Frame: Up to 5 years ]Assessed by National Cancer Institute Common Terminology Criteria for Adverse Events (CTCAE) version 4.0 (version 5.0 will be utilized for serious adverse events reporting only). Toxicity rates can be estimated to within at least +/- 18% with 95% confidence.
- Non-invasive genotyping and circulating tumor deoxyribonucleic acid (DNA) assessment [ Time Frame: Up to 5 years ]Sensitivity, specificity, positive predictive value, negative predictive value, and kappa coefficient will be used to evaluate the concordance. Will evaluate the association of detection of active lymphoma by positron emission tomography-computed tomography and the detection of circulating tumor DNA in plasma at baseline, after 6 and 12 cycles, and at 30 months after initiation of study therapy. Chi-square test will be used to evaluate the association and odds ratio will be calculated
- Active lymphoma and circulating tumor DNA in plasma [ Time Frame: From baseline up to 30 months after initiation of treatment ]The Cox proportional hazards model will be used to assess the association and odds ratio will be calculated.
- m7-FLIPI model validation [ Time Frame: Up to 5 years ]The Cox proportional hazards model will be used to assess the association of the m7-FLIPI with to PFS.

The intent is to enroll patients with FL relapsed within 2 years of completing their first course of chemotherapy (CHOP or bendamustine based therapy) + anti-CD20 therapy. Patient is still eligible if he/she received radiation therapy or anti-CD20 therapy prior to chemoimmunotherapy or if maintenance anti-CD20 therapy was administered after chemoimmunotherapy
- Patients must have either failed to achieve a complete remission, or must have relapsed within 2 years after completing CHOP or bendamustine-containing chemoimmunotherapy (including an anti-CD20 monoclonal antibody), as measured from the last dose of CHOP or bendamustine; relapsed patients must not have received any intervening chemotherapy
- Patients must have received only 1 course of chemotherapy, containing at least 3 cycles of CHOP or bendamustine; (note that no minimum dose of bendamustine is required)
- Patients who received any anti-CD20 antibody therapy prior to CHOP or bendamustine are eligible
