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. ^{1 2 3 4 5}

Why 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. ^{5 6 7 8 9}

What Are the Treatments Tested in This Trial?

Interventions

• Brentuximab Vedotin
• CHEP

Trial Overview

The trial tests an investigational treatment named BV-CHEP which combines brentuximab vedotin (an FDA-approved drug for some lymphomas) with standard chemotherapy drugs cyclophosphamide, doxorubicin, etoposide and prednisone. The aim is to see if this combination works better in patients whose ATLL cells express CD30 protein markers.

How Is the Trial Designed?

Group I: Open-label, Multicenter, Single-Arm Experimental Treatment 2 Interventions

This is a single-arm intervention where patients will receive concurrent therapy with BV+CHEP \[(brentuximab vedotin; 1.8 mg/kg IV, on D1 every 21 days) (cyclophosphamide 750 mg/m\^2 on D1; doxorubicin 50 mg/m\^2 on D1, etoposide 100 mg/m\^2 IV infusion on D1-3; prednisone 100 mg orally once daily on D1-5; cycle length every 21 days)\] for 2 to 6 cycles of induction therapy. After 6 cycles of BV + CHEP, responders (CR, PR or SD) who are not eligible for BMT and have CD30-positive ATLL will continue maintenance therapy with BV alone (1.8 mg/kg IV, every 21 days) until disease progression, withdrawal due to toxicity or death.

Brentuximab Vedotin is already approved in United States, European Union for the following indications:

Published Research Related to This Trial

Brentuximab vedotin, an antibody-drug conjugate used for treating certain lymphomas, showed improved progression-free survival in patients with cutaneous T-cell lymphoma (CTCL) without a direct correlation to the drug's exposure levels, indicating its efficacy is consistent across different exposure ranges.

The study found that while higher exposure to the drug was linked to an increase in severe treatment-emergent adverse events (TEAEs), the results support the use of a standard dose of 1.8 mg/kg every 3 weeks, with the option for dose reductions in patients experiencing significant side effects.

Population PK and Exposure-Response Relationships for the Antibody-Drug Conjugate Brentuximab Vedotin in CTCL Patients in the Phase III ALCANZA Study. Suri, A., Mould, DR., Liu, Y., et al.[2019]

A phase 2 study demonstrated promising efficacy of brentuximab vedotin, an antibody-drug conjugate, in treating patients with relapsed or refractory peripheral T-cell lymphoma (PTCL).

The results suggest that BV could be a valuable treatment option for patients who have not responded to previous therapies.

Time has come for immunotherapy in PTCL. Bachy, E., Coiffier, B.[2021]

Brentuximab vedotin (BV) combined with cyclophosphamide, doxorubicin, and prednisone (BV-CHP) has shown improved outcomes in treating common nodal CD30+ peripheral T-cell lymphomas (PTCLs) compared to the traditional treatment regimen, indicating a significant advancement in therapy.

Further research is needed to determine the optimal level of CD30 expression for effective BV-CHP therapy and to assess its efficacy and safety in less common subtypes of CD30+ PTCLs.

In a study of 67 patients with cutaneous T-cell lymphoma (CTCL), brentuximab vedotin (BV) demonstrated a 67% overall response rate, with particularly high efficacy in patients with CD30+ lymphoproliferative disorders (84%) and folliculotropic mycosis fungoides (71%).

The treatment was generally well-tolerated, with the most common side effect being peripheral neuropathy, which was mostly mild (grades 1 or 2) in 57% of patients, indicating that BV is both effective and relatively safe for advanced-stage CTCL.

In a study of 1344 patients with peripheral T-cell lymphoma (PTCL), those treated with brentuximab vedotin plus cyclophosphamide, doxorubicin, and prednisone (A + CHP) had a lower rate of subsequent therapy compared to those treated with CHOP, indicating potentially better initial treatment efficacy.

The study highlighted that patients in the real-world setting were older and had more comorbidities than those in clinical trials, emphasizing the need for retrospective analyses to understand the impact of new treatments in diverse patient populations.

Retrospective Analysis With Propensity Score Matching of Peripheral T-Cell Lymphoma Treated Frontline With Brentuximab Vedotin and Chemotherapy. Burke, JM., Liu, N., Yu, KS., et al.[2023]

Brentuximab vedotin significantly reduced symptom burden in patients with CD30-expressing cutaneous T-cell lymphoma compared to physician's choice treatments, with a mean maximum reduction in symptom scores of -27.96 versus -8.62, exceeding the minimally important difference.

Quality of life measures, including FACT-G and EQ-5D scores, remained comparable between brentuximab vedotin and physician's choice, indicating that the treatment did not adversely affect patients' overall well-being, even in those experiencing peripheral neuropathy.
