This study is for patients with cancer and is being done to see if blood samples from patients with and without certain types of cancer help researchers develop a future blood test for use in detecting cancer early.

The purpose of this research study is to find new ways of detecting and treating Hodgkin lymphoma and primary mediastinal B-cell lymphoma (a cancer of mature B-lymphocytes). It is a form of non-Hodgkin lymphoma, a type of cancer that originates in cells of the immune system, called lymphocytes. The information we learn by doing this research study may help study doctors identify new ways of treating your type of lymphoma. Participants in this study will provide archival (stored) tissue and blood samples. Participation is expected to last about 8 months. The risks and discomforts of this study are minimal. All blood specimens requested for this study will be collected at the time of routine procedures.

This is a study for patients with relapsed/refractory large B-cell lymphoma or follicular lymphoma. Patients who have either stable disease or a partial response to CD19 CAR T-Cell therapy may be eligible. The purpose of the study is to compare groups of patients who either receive therapy after CAR T-cells and patients that do not receive further therapy after CAR T-cells.

This study is for subjects that have been diagnosed with Follicular Lymphoma.
This study is testing an investigational drug(s) called Epcoritamab that is not approved by the FDA (Food and Drug Administration). The purpose of this study is to see if the combination of the study drug epcoritamab with rituximab and lenalidomide has a better response rate than standard of care chemoimmunotherapy in the treatment of follicular lymphoma. The total study treatment duration is up to 2.5 years. You may stop the study treatment early if you do not respond after 6 months, your disease worsens, you no longer tolerate the study drug(s), or you withdraw from the study.

Once you finish the study treatment or discontinued study treatment early, you will continue to the Post-Study Treatment Follow Up Period, you will come back to the study clinic every 6 months for the first 3 years and then yearly to have imaging scans and blood work to check if your disease is in remission or worsen.

If your disease worsens or if you start a new FL treatment, you will enter the Long-term Follow Up Period, you will be called by telephone or your health record will be reviewed to check on your well-being and to see what your next treatment plan will be. This follow-up may last up to 15 years.

This study is for subjects diagnosed with follicular lymphoma. The purpose of this study is to assess if treatment with Mosunetuzumab can improve long term remission in patients with low tumor burden follicular lymphoma compared to rituximab. The treatment period for the Rituximab arm is approximately 40 weeks. The treatment period for the Mosunetuzumab arm is approximately 24 weeks. However the subject may remain in the study for up to 10 years for the follow-up period.
