Experimental: Odronextamab + Chemotherapy - Part 1 of the study includes ordonextamab dose escalation for participants with previously untreated FL and relapsed/refractory FL (Part 1A only) followed by a randomized exploration of 2 regimens of odronextamab (Odro) and cyclophosphamide, doxorubicin, vincristine, prednisone (CHOP) with the objective of dose optimization (Part 1B) in previously untreated patients with FL.

Active comparator: Rituximab + Chemotherapy - In Part 2 only, participants will be randomized 1:1:1 to receive rituximab (R) with chemotherapy (CHOP), followed by rituximab monotherapy maintenance.

Experimental: Odronextamab + Chemotherapy + Maintenance - In Part 2, participants will be randomized 1:1:1 to receive odronextamab with chemotherapy \[CHOP, or cyclophosphamide, vincristine, and prednisone (CVP)\], followed by odronextamab monotherapy maintenance.

Experimental: Odronextamab + Chemotherapy + No maintenance - In Part 2, participants will be randomized 1:1:1 to receive odronextamab with chemotherapy (CHOP, or CVP) without maintenance.

Summary
Brief summary
This study is researching an experimental drug called odronextamab, referred to as study drug. The study is focused on participants with previously untreated follicular lymphoma. Follicular lymphoma is a type of non-Hodgkin lymphoma or NHL. Participants with follicular lymphoma that has come back after treatment (called "relapsed") or did not respond to treatment (called "refractory") are eligible to take part only in Part 1A of the study.

This study is made up of 3 parts: Part 1A (non-randomized), Part 1B and Part 2 (randomized - controlled).

The aim of Part 1A and Part 1B of the study is to see how safe and tolerable the study drug in combination with chemotherapy is and to determine the dose and schedule of the study drug to be combined with chemotherapy to be used in Part 2 of the study.

The aim of Part 2 of the study is to assess how effective the combination of the study drug with chemotherapy is in comparison with the combination of rituximab and chemotherapy (the current standard-of-care for NHL). Standard-of-care means the usual medication expected and used when receiving treatment for a condition.

The study is looking at several other research questions, including:

* What side effects may happen from taking the study drug
* How much study drug is in the blood at different times
* Whether the body makes antibodies against the study drug (which could make the study drug less effective or could lead to side effects)
* The impact from the study drug on quality-of-life and ability to complete routine daily activities
