Relapsed/Refractory Follicular Lymphoma

The purpose of the study is to compare the efficacy of zanubrutinib plus obinutuzumab versus lenalidomide plus rituximab (R\^2) in participants with relapsed/refractory (R/R) follicular lymphoma (FL), as measured by progression-free survival as determined by an independent review committee in accordance with the 2014 modification of the International Working Group on non-Hodgkin lymphoma (NHL) Criteria based on n positron emission tomography and computed tomography (PET/CT), and to compare the efficacy of zanubrutinib plus rituximab versus R\^2 in participants with R/R marginal zone lymphoma (MZL), as measured by progression free survival (PFS) assessed by IRC in accordance with CT-based Lugano 2014 Criteria.

This study is researching an experimental drug called odronextamab (referred to as study drug), in combination with lenalidomide. The study is focused on participants who have one of two types of cancer: follicular lymphoma (FL) or marginal zone lymphoma (MZL) that has come back after treatment (called "relapsed"), or did not respond to treatment (called "refractory"). FL and MZL are subtypes of Non-Hodgkin 's lymphoma (NHL). This study will be made up of two parts (Part 1 not randomized, Part 2 randomized - controlled). The aim of Part 1 of the study is to see how safe and tolerable the study drug is when used in combination with lenalidomide, in participants with FL or MZL, and to determine the dose of the study drug to be used in Part 2 of this study. This combination is considered "first-in-human" as it has not been tested as a combination treatment in humans before. The aim of Part 2, of the study is to assess how well the combination of the study drug and lenalidomide works compared to the combination of rituximab (called "the comparator drug") and lenalidomide. The combination of comparator drug and lenalidomide is the current standard-of-care treatment for relapsed/refractory FL and/or MZL. 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 in combination with lenalidomide * 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

This is a prospective, open-label, single-arm, single-center, Phase II clinical study designed to evaluate the efficacy and safety of zanubrutinib, rituximab, and lenalidomide (ZR²) in combination with tislelizumab in patients with relapsed/refractory follicular lymphoma who have relapsed or are refractory after ≥1 prior systemic therapy. After successful screening, enrolled patients will receive 6 treatment cycles (21 days per cycle). Disease response will be assessed by CT/PET-CT during treatment and after completion of induction. Patients who achieve CR/PR/SD will proceed to the maintenance phase; patients who do not achieve at least SD (i.e., fail to reach CR/PR/SD) during induction will discontinue the study. Patients with CR/PR/SD after induction will receive maintenance therapy with zanubrutinib plus tislelizumab until disease progression, unacceptable toxicity, or completion of 1 year of maintenance. Efficacy and safety assessments will be performed per protocol. Tumor response will be assessed by site investigators according to the 2014 Lugano criteria, including determination of response status, date of response, and date of progression/relapse.

Retrospective, multicenter observational study to evaluate the response to treatment with Mosunetuzumab in relapsed/refractory Follicular Lymphoma (FL) after at least three lines of therapy, within the Compassionate Use Program (CUP).

This study is a randomized, controlled, double-blind, multicenter, phase III clinical study to evaluate the efficacy of IMM0306 (Amulirafusp Alfa)in combination with lenalidomide versus placebo in combination with lenalidomide in patients with Relapsed/Refractory Follicular lymphoma. Primary endpoints are Complete Remission Rate (CRR) and Progression-Free Survival (PFS).

This is a multicenter, single-arm, open-label, investigator-initiated, phase II clinical trial designed to evaluate the feasibility, efficacy, and safety of Mosunetuzumab in combination with Tislelizumab in patients with relapsed/refractory follicular lymphoma (r/r FL).
