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.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

Exclusion Criteria

1. FL grade 3B or transformed FL.
2. \[Removed\]

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.
