Clinical summary

Summary

This study is recruiting people with relapsed or refractory Follicular Lymphoma (FL) and Marginal Zone Lymphoma (MZL), and is testing different treatments depending on which disease you have.

People with Follicular Lymphoma will be randomly allocated to either the Experimental or Active Comparator Arms.

  • In the Experimental Arm, people with FL will receive a combination of targeted therapies: zanubrutinib and obinutuzumab. Once they have finished receiving the combination treatment, participants will continue receiving zanubrutinib alone.
  • In the Active Comparator Arm, people with FL will receive targeted therapy (rituximab) plus lenalidomide, which is a drug that modifies the response of the immune system.

People with Marginal Zone Lymphoma will be randomly allocated to either an Experimental or Active Comparator Arm.

  • In the Experimental Arm, people with MZL will receive combination targeted therapy (zanubrutinib + rituximab). Once they have finished receiving the combination treatment, participants will continue receiving zanubrutinib alone.
  • In the Active Comparator Arm, people with MZL will receive targeted therapy (rituximab) plus lenalidomide, which is a drug that modifies the response of the immune system.
