Brentuximab Vedotin + CHEP for Adult T-Cell Leukemia/Lymphoma
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial tests a new treatment for adult T-cell leukemia/lymphoma (ATLL), a rare cancer type. The study aims to evaluate patient responses to a combination of brentuximab vedotin (also known as Adcetris, SGN-35, or cAC10-vcMMAE) and a standard chemotherapy mix called CHEP. This treatment is not yet approved for ATLL, so researchers are exploring its effectiveness, particularly concerning a marker called CD30 on cancer cells. The trial suits those diagnosed with ATLL, who have had limited prior treatment, and whose cancer cells express the CD30 marker. As a Phase 2 trial, the research focuses on measuring the treatment's effectiveness in an initial, smaller group of people.
Will I have to stop taking my current medications?
The trial does not specify if you must stop taking your current medications, but it does exclude patients taking certain medications like ketoconazole, itraconazole, and others listed in the patient handout. It's best to discuss your current medications with the trial team to see if any adjustments are needed.
Is there any evidence suggesting that this treatment is likely to be safe for humans?
Research has shown that brentuximab vedotin, when combined with other chemotherapy drugs, generally has a manageable safety profile for patients with T-cell lymphomas. Serious side effects, such as pneumonia and fever, have been reported but are uncommon, affecting about 4% of patients. Other side effects, like nausea and vomiting, occur in 2-3% of cases.
In another study, brentuximab vedotin was combined with cyclophosphamide, doxorubicin, etoposide, and prednisone, a treatment known as BV-CHEP. The results were positive for patients with CD30-positive T-cell lymphomas, with some achieving remission.
The treatment's safety is supported by its FDA approval for other types of lymphomas, indicating it has been tested in many patients and found safe for those conditions. However, the use of etoposide in this study is new, and researchers believe it will improve patient outcomes.
Prospective trial participants should consider that while the treatment is generally well-tolerated, there are risks of side effects, as with any cancer treatment.12345Why are researchers excited about this study treatment for adult T-cell leukemia/lymphoma?
Researchers are excited about the combination of Brentuximab Vedotin (BV) and CHEP for treating Adult T-Cell Leukemia/Lymphoma (ATLL) because it targets CD30-positive cancer cells, which are commonly found in ATLL. Unlike standard treatments that primarily rely on chemotherapy regimens, Brentuximab Vedotin is an antibody-drug conjugate, providing a more targeted approach by delivering chemotherapy directly to cancer cells, potentially reducing damage to healthy cells. This targeted mechanism could lead to more effective treatments with fewer side effects, offering new hope for patients with this challenging condition.
What evidence suggests that this treatment might be an effective treatment for ATLL?
Research shows that a treatment combining brentuximab vedotin with other chemotherapy drugs, such as cyclophosphamide, doxorubicin, etoposide, and prednisone (BV-CHEP), holds promise for aggressive adult T-cell leukemia/lymphoma (ATLL). Participants in this trial will receive the BV-CHEP combination. Previous studies have demonstrated that brentuximab vedotin, when used with similar chemotherapy drugs, resulted in complete responses in patients with T-cell lymphomas, including ATLL, meaning the cancer was no longer detectable after treatment. High overall response rates and complete remission rates support the effectiveness of this combination. Adding etoposide is expected to further improve outcomes, as it has proven helpful in treating other types of T-cell lymphomas.56789

Are You a Good Fit for This Trial?
This trial is for adults over 18 with a specific type of cancer called Adult T-cell leukemia/lymphoma (ATLL), who have not been treated or have had only one round of chemotherapy. They must test negative for HIV, show adequate organ function, and if they can bear children, agree to use effective contraception methods. People with severe liver or kidney problems, active brain lymphoma lesions, certain other cancers, allergies to the study drugs or components, taking prohibited medications, previous brentuximab vedotin treatment, significant neuropathy or symptomatic heart disease are excluded.Inclusion Criteria
Exclusion Criteria
Timeline for a Trial Participant
Screening
Participants are screened for eligibility to participate in the trial
Treatment
Participants receive BV-CHEP therapy for 2-6 cycles, each cycle lasting 21 days, with PET/CT scans to assess disease progression
Maintenance
Participants who are not eligible for a bone marrow transplant and have CD30-positive ATLL may continue on brentuximab vedotin alone until disease progression
Follow-up
Participants are monitored for survival and disease progression with PET/CT or CT scans and blood tests every 6 months for 2 years, and followed for survival for up to 5 years
