What side effects are associated with this type of intervention?

Common treatments for Lymphocytic Leukemia/Lymphoma, such as Rituximab and High Dose Methylprednisolone (HDMP), have several known side effects. Rituximab can cause infusion reactions, prolonged neutropenia, hypogammaglobulinemia, and increased risk of infections. High Dose Methylprednisolone can lead to hyperglycemia, hypertension, increased risk of infections, osteoporosis, and gastrointestinal issues. Combining these treatments may increase the risk of infections and other immune-related side effects.

What prior FDA approvals exist?

Rituximab, a monoclonal antibody targeting CD20 on B-cells, has been FDA-approved for the treatment of various types of lymphocytic leukemia and lymphoma, including chronic lymphocytic leukemia (CLL) and non-Hodgkin lymphoma (NHL). It is often used in combination with chemotherapy agents such as fludarabine, cyclophosphamide, and bendamustine. High Dose Methylprednisolone (HDMP), a corticosteroid, is used to reduce inflammation and modulate the immune response, and while not specifically approved as a standalone treatment for lymphocytic leukemia/lymphoma, it is commonly used in combination with other therapies to enhance their efficacy. Other related FDA-approved drugs include ibrutinib and venetoclax, which are used in combination with rituximab for CLL treatment.

What other types of research exist?

Promising novel alternatives to Rituximab and HDMP for Lymphocytic Leukemia/Lymphoma patients include: 1) Ibrutinib, a Bruton's tyrosine kinase (BTK) inhibitor, which has shown efficacy in CLL/SLL. 2) Venetoclax, a BCL-2 inhibitor, which is effective in inducing apoptosis in cancer cells. 3) CAR T-cell therapies, such as KTE-X19, which have shown significant activity in relapsed or refractory cases. 4) Obinutuzumab, a glycoengineered anti-CD20 monoclonal antibody, which may offer enhanced efficacy over Rituximab.

Study Summary

This trial is looking at whether giving high dose methylprednisolone with rituximab before starting venetoclax can reduce the amount of cancer cells and make it safer to take venetoclax.

Who is the study for?

Adults with relapsed or refractory chronic lymphocytic leukemia (CLL) or small lymphocytic lymphoma (SLL), who have had at least one prior treatment but not venetoclax in the last 6 months, can join. They must be generally healthy, understand the study, and agree to use contraception. Excluded are those with severe allergies to monoclonal antibodies, recent heart attacks, uncontrolled infections or other cancers that could interfere.Check my eligibility

What is being tested?

The trial tests if rituximab combined with high-dose methylprednisolone (HDMP) can reduce cancer cells before starting venetoclax for CLL/SLL patients. Depending on their risk of tumor lysis syndrome (TLS), participants will either receive HDMP/rituximab first or start directly on venetoclax. The goal is to see if this reduces TLS risk when beginning venetoclax therapy.See study design

What are the potential side effects?

Possible side effects include kidney problems or abnormal heart rhythms due to rapid cancer cell breakdown (TLS). Other risks may involve reactions related to infusion treatments and the individual drugs' typical side effects like immune system impacts and organ inflammation.

Other Research

Rituximab, a monoclonal antibody, targets the CD20 antigen on B-cells, leading to their destruction through antibody-dependent cellular cytotoxicity (ADCC) and complement-dependent cytotoxicity (CDC). High Dose Methylprednisolone (HDMP) is a corticosteroid that reduces inflammation and modulates the immune response, helping to decrease tumor burden and alleviate symptoms. These mechanisms are vital for Lymphocytic Leukemia/Lymphoma patients as they directly target malignant B-cells and manage disease symptoms, improving overall outcomes and quality of life.
