Venetoclax + Obinutuzumab + Epcoritamab for Chronic Lymphocytic Leukemia
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial explores a new combination of drugs to treat chronic lymphocytic leukemia (CLL) and small lymphocytic lymphoma (SLL) in individuals who haven't received prior treatment. It combines venetoclax and obinutuzumab, known for their effectiveness, with a new drug called epcoritamab, an experimental treatment. The aim is to determine if adding epcoritamab can enhance cancer treatment effectiveness and duration. Individuals with CLL or SLL who experience active symptoms, such as extreme fatigue or significant weight loss, might be suitable candidates for this trial. As a Phase 2 trial, the research focuses on assessing the treatment's effectiveness in an initial, smaller group, offering a chance to benefit from potentially effective new therapies.
Do I need to stop my current medications to join the trial?
The trial information does not specify if you need to stop taking your current medications. However, it mentions that chronic use of corticosteroids above a certain dose is not allowed, and certain conditions related to anticoagulants and infections are considered. It's best to discuss your specific medications with the trial team.
Is there any evidence suggesting that this trial's treatments are likely to be safe?
Research shows that using venetoclax and obinutuzumab together is a common treatment for chronic lymphocytic leukemia (CLL) and small lymphocytic lymphoma (SLL). Studies have found this combination to be safe and effective. Early findings suggest that adding epcoritamab to these two is well-tolerated.
Regarding side effects, venetoclax and obinutuzumab are generally well-tolerated, though patients might experience mild to moderate issues like low blood cell counts or infections, which can be managed. Epcoritamab, being newer, may cause injection site reactions and flu-like symptoms, which are typical for these treatments.
Overall, this combination treatment is designed to be safe. However, like any treatment, some side effects may occur. It's important to discuss expectations with the trial team.12345Why are researchers excited about this trial's treatments?
Researchers are excited about the combination of venetoclax, obinutuzumab, and epcoritamab for treating Chronic Lymphocytic Leukemia (CLL) because it introduces a novel multi-pronged approach. Unlike traditional treatments like BTK inhibitors or chemoimmunotherapy, this regimen uses venetoclax to induce cancer cell death by targeting the BCL-2 protein, obinutuzumab to enhance the immune system's attack on cancer cells, and epcoritamab, a bispecific antibody that further stimulates immune cells to recognize and destroy cancer. This combination could potentially offer a more comprehensive attack on CLL cells, leading to better outcomes for patients.
What evidence suggests that this trial's treatments could be effective for chronic lymphocytic leukemia?
Research has shown that combining venetoclax and obinutuzumab effectively treats chronic lymphocytic leukemia (CLL). One study found that this combination helped more than half of the patients live for six years without their cancer worsening. Obinutuzumab targets and attacks cancer cells, while venetoclax blocks a protein that helps cancer cells survive. In this trial, participants will receive venetoclax, obinutuzumab, and epcoritamab. Adding epcoritamab, which aids the immune system in attacking cancer, might enhance the treatment's effectiveness and duration. Research supports these treatments, suggesting they offer a promising option for people with untreated CLL.678910

Trial Overview
The LonGEVity trial is testing a combination of venetoclax and obinutuzumab followed by epcoritamab in patients with CLL/SLL. Venetoclax targets proteins that cancer cells need to survive, while obinutuzumab and epcoritamab are antibodies designed to help the immune system attack cancer cells.
How Is the Trial Designed?

Treatment groups
Experimental Treatment
Patients receive obinutuzumab IV on days 1, 2, 8 and 15 of cycle 1 and on day 1 of cycles 2-6, venetoclax PO QD on days 22-28 of cycle 1 and on days 1-28 of cycles thereafter, as well as epcoritamab SC on days 1, 8, 15, and 22 of cycles 7-9 and on day 1 of cycles thereafter. Cycles repeat every 28 days for up to 12 cycles in the absence of disease progression or unacceptable toxicity. After completion of 12 cycles, patients who are MRD positive and have CR, PR, or SD continue receiving epcoritamab SC on day 1 of each cycle. Cycles of epcoritamab repeat every 28 days for 6 cycles in the absence of disease progression or unacceptable toxicity. All patients also undergo blood sample collection and CT or MRI throughout the study. Additionally, patients may undergo bone marrow aspiration and biopsy throughout the study.
