About this trial

The purpose of this study is to determine how effective and safe the combination of rituximab and epcoritamab is in treating patients with Follicular Lymphoma (FL) and who have not received other treatments for their lymphoma.

The names of the study drugs involved in this study are:

* Rituximab (a type of monoclonal antibody therapy) * Epcoritamab (a T-cell bispecific antibody)

Eligibility criteria

This trial does not accept healthy volunteers

Qualifiers

Histologically confirmed diagnosis of CD20+ FL (grade 1-3A) with review of the diagnostic pathology specimen at one of the participating institutions. Patients with current or prior histologic transformation are excluded.

No prior systemic therapy for FL. Prior treatment with radiation therapy or short course steroids is allowed.

Symptomatic adenopathy

Organ function impairment due to disease involvement, including cytopenias due to marrow involvement (WBC <1.5x109/L; absolute neutrophil count [ANC] <1.0x109/L, Hgb <10g/dL; or platelets <100x109/L)

Disqualifiers

Patients who require systemic immunosuppressive therapy for an ongoing medical condition will be excluded. For corticosteroids, patients receiving a prednisone dose of >10 mg daily (or equivalent) will not be eligible. A short course of steroids (up to 14 days) for symptom palliation is allowed, in which case patients should be off steroids prior to treatment start.

Patients with bulky cervical adenopathy that is compressing the upper airway or could result in significant airway compression during a tumor flare event.

Patients with stage I follicular lymphoma

Patients who are candidates for radiation therapy with curative intent (in the opinion of the treating investigator)

Trial outcomes

Primary outcomes

1

End of Treatment (EOT) Complete Metabolic Response (CMR) Rate

EOT CMR rate defined as the proportion of participants achieving CR per PET/CT Lugano 2014 criteria (protocol appendix B) at the EOT assessment: PET-CT, score 1, 2, or 3 with or without a residual mass on a 5-point scale (5PS) among all patients and separately in Cohorts A and B.

Time frame
(Cycle 1 = 36 days, cycle 2-9 = 28 days), up to 267 days

Secondary outcomes

1

Best Partial Metabolic Response (PMR) Rate

Best PMR rate defined as the proportion of participants achieving PR per Lugano 2014 criteria (protocol appendix B) ever on treatment: PET-CT Score 4 or 5 with reduced uptake compared with baseline and residual mass(es) of any size or on CT, ≥ 50% decrease in SPD of up to 6 target measurable nodes and extranodal sites; no increase in non-measured lesions; spleen if enlarged must have regressed by \>50% in length beyond normal.

Time frame
(Cycle 1 = 36 days, cycle 2-9 = 28 days), up to 267 days
2

Best Objective Metabolic Response (OMR) Rate

Best OMR rate defined as the proportion of participants achieving CR or partial response (PR) per Lugano 2014 criteria (protocol appendix B) ever on treatment.

Time frame
(Cycle 1 = 36 days, cycle 2-9 = 28 days), up to 267 days
3

EOT Partial Metabolic Response (PMR) Rate

EOT PMR rate defined as the proportion of participants achieving PR per PET/CT Lugano 2014 criteria (protocol appendix B) at the EOT assessment: PET-CT Score 4 or 5 with reduced uptake compared with baseline and residual mass(es).

Time frame
(Cycle 1 = 36 days, cycle 2-9 = 28 days), up to 267 days
4

EOT Objective Metabolic Response (OMR) Rate

EOT OMR rate defined as the proportion of participants achieving CR or partial response (PR) per PET/CT Lugano 2014 criteria (protocol appendix B) at the EOT assessment.

Time frame
