Loncastuximab tesirine + Rituximab
During the 12-week Induction Phase (Cycles 1 to 4), participants will receive loncastuximab tesirine on days 1 of each 3-week cycle for Cycles 1 through 4; and rituximab on days 1, 8, 15 of Cycle 1 and day 1 of Cycle 2.
Maintenance Phase 1 (Cycle 5) is 8 weeks: Participants achieving complete response (CR) or partial response (PR) during the Induction Phase will receive loncastuximab tesirine once every 3-weeks; and rituximab once during week 7 or 8. Participants achieving a response of Stable Disease (SD) or Progressive Disease (PD) will be taken off treatment.
Maintenance Phase 2 (Cycles 6 and 7) is 16 weeks:
* Participants achieving CR during Maintenance Phase 1 receive rituximab once during week 7 or 8 of Cycles 6 and 7.
* Participants achieving PR during Maintenance Phase 1 receive loncastuximab tesirine once every 3-weeks over each 8 week cycle; and rituximab once during week 7 or 8 of Cycles 6 and 7.
* Participants achieving SD or PD will be taken off treatment.
Loncastuximab tesirine
Induction Phase (Cycles 1 through 4):
* 150 μg/Kg of loncastuximab tesirine administered via intravenous infusion (given as per treatment guidelines) on Days 1 of a 3-week cycle during Cycles 1 and 2.

Rituximab
Induction Phase (Cycles 1 through 4): 375 mg/m2 rituximab on days 1, 8, 15 of cycle 1 and day 1 of cycle 2 via intravenous infusion (given as per treatment guidelines) or subcutaneous 1400 mg/23,400 units hyaluronidase during Cycles 1 and 2, per discretion of treating physician. Rituximab will not be administered during Cycles 3 and 4.
Maintenance Phase 1 (Cycle 5): Participants achieving a response of PR or CR will receive 375 mg/m2 rituximab during week 1 of a 8-week cycle via intravenous infusion (given as per treatment guidelines) or subcutaneous 1400 mg/23,400 units hyaluronidase, per discretion of treating physician.
Maintenance Phase 2 (Cycles 6 and 7): Participants achieving a response of PR or CR will receive 375 mg/m2 rituximab during week 1 of each 8-week cycle via intravenous infusion (given as per treatment guidelines) or subcutaneous 1400 mg/23,400 units hyaluronidase, per discretion of treating physician.

Eligibility Criteria
Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.
Inclusion Criteria
2. Patients must have histologic confirmation of Follicular Lymphoma (FL) (grade 1, 2 and 3A). Note: Participants who have received previous CD19-directed therapy must have a biopsy which shows CD19 expression after completion of the CD19-directed therapy.
3. Patients with relapsed or refractory FL previously treated with ≥1 line of systemic therapy having ≥ 1 Groupe d'Etude des Lymphomes (GELF) criteria for therapy, or Progression of Diseases within 24 months (POD24), or second relapse.
4. Baseline FDG-PET/CT scans must demonstrate positive lesions compatible with CT defined anatomical tumor sites. Patients should have at least one measurable site of disease per Lugano classification.
5. Patient should have ≥ 1 Groupe d'Etude des Lymphomes (GELF) criteria for treatment initiation).
* Involvement of ≥3 nodal sites, each with diameter of ≥3 cm
* Any nodal or extranodal tumor mass with a diameter of ≥7 cm
* B symptoms (fever ≥ 38 degrees Celsius of unclear etiology, night sweats, weight loss \> 10% within the prior 6 months).

* Hemoglobin ≥ 10 g/dL or ≥8 g/dL in case of bone marrow involvement by lymphoma.
* Total bilirubin \< 1.5 x within normal institutional limits (unless due to lymphoma involvement of liver or a known history of Gilbert's disease).
* Gamma-Glutamyl Transpeptidase (GGT)/Aspartate Aminotransferase (AST)/(SGOT)/Alanine Aminotransferase (ALT)(SGPT) ≤ 2.5 × institutional upper limit of normal.
* Creatinine within normal institutional limits, or creatinine clearance ≥30 ml/min/1.7m\^2 for patients with creatinine levels above institutional normal (unless due to lymphoma).
Exclusion Criteria
2. \[Removed\]
3. ≥ 6 lines of systemic immunochemotherapy for treatment of FL.
4. Patients with clinically significant pleural effusions and/or ascites requiring drainage or associated with shortness of breath.
5. Patients receiving any other investigational agents.

9. Serologic status reflecting active hepatitis B or C infection. Patients that are positive for hepatitis B core antibody, hepatitis B surface antigen (HBsAg), or hepatitis C antibody will need a negative polymerase chain reaction (PCR) prior to enrollment. (PCR positive patients will be excluded.) Hepatitis C antibody positive patients are eligible if PCR is negative. Hepatitis B core antibody (+) patients without evidence of HBsAg or Hep B PCR (+) are eligible with appropriate Hepatitis B reactivation prophylaxis.
