What You Need to Know Before You Apply

What is the purpose of this trial?

This trial tests a new treatment plan for individuals with classical Hodgkin lymphoma who have not received prior treatment. The goal is to evaluate the effectiveness of pembrolizumab (an immunotherapy drug), administered alone or with other drugs like brentuximab vedotin or a chemotherapy mix, for patients with varying health and strength levels. Participants will be divided into groups based on their fitness and will receive different combinations of these medications. Suitable candidates for this trial include those diagnosed with classical Hodgkin lymphoma and experiencing symptoms that impact daily life. As a Phase 2 trial, this research focuses on assessing the treatment's effectiveness in an initial, smaller group of participants.

Will I have to stop taking my current medications?

The trial does not specify if you need to stop taking your current medications, but if you are taking a strong CYP3A4 modulator, you will need to stop it and complete a washout period (time without taking the medication) of 4 weeks or 5 times the half-life of the drug, whichever is shorter.

Is there any evidence suggesting that this trial's treatments are likely to be safe?

Research has shown that using pembrolizumab with AVD chemotherapy is safe for people with untreated Hodgkin's lymphoma. Studies indicate that this combination does not cause serious treatment delays, making it generally well-tolerated.

Research has found the combination of pembrolizumab and brentuximab vedotin to be an effective and safe treatment for Hodgkin's lymphoma, with significant improvements in survival rates and no major safety issues.

Overall, both treatment combinations in this trial have demonstrated promising safety results in earlier research. ^{1 2 3 4 5}

Why are researchers excited about this trial's treatments?

Researchers are excited about pembrolizumab-based therapy for Hodgkin's lymphoma because it introduces a novel approach by incorporating pembrolizumab, a type of immunotherapy known as a checkpoint inhibitor. Unlike traditional chemotherapy regimens such as ABVD (Adriamycin, Bleomycin, Vinblastine, Dacarbazine), pembrolizumab works by unleashing the immune system to attack cancer cells more effectively. This therapy is being tested in different combinations tailored for various patient needs, including fit, frail, and unfit cohorts. By potentially enhancing the body's own immune response, these treatments could offer a more targeted and less toxic alternative to conventional chemotherapy.

What evidence suggests that this trial's treatments could be effective for Hodgkin's Lymphoma?

Research has shown that using pembrolizumab with chemotherapy drugs like AVD (which includes doxorubicin, vinblastine, and dacarbazine) effectively treats Hodgkin's lymphoma. One study found that patients remained relapse-free for nearly three years with this treatment combination. In this trial, participants in the Fit Cohort will receive pembrolizumab with AVD.

Additionally, pembrolizumab, when combined with brentuximab vedotin, has helped patients with classical Hodgkin lymphoma live longer. Participants in the Frail Cohort of this trial will receive pembrolizumab with brentuximab vedotin.

This combination of treatments has shown promise for both new and recurrent cases, making it a strong option for managing the condition. These findings support its potential effectiveness in this trial. ^{1 3 6 7 8}

Published Research Related to This Trial

In a phase II trial involving 170 patients with early-stage unfavorable Hodgkin lymphoma, the combination of brentuximab vedotin plus doxorubicin, vinblastine, and dacarbazine (BV-AVD) resulted in a higher PET-negative response rate (82.3%) after two cycles compared to the standard ABVD treatment (75.4%).

The 2-year progression-free survival (PFS) rate was also higher in the BV-AVD group (97.3%) compared to the ABVD group (92.6%), indicating that BV-AVD may offer a more effective treatment option for these patients.

Brentuximab vedotin, a targeted therapy for Hodgkin lymphoma, is effective for patients at high risk of recurrence or relapse, but it can cause significant side effects, particularly peripheral neuropathy.

For patients who relapse after brentuximab vedotin, anti-PD1 immunotherapy (nivolumab or pembrolizumab) is an option, though it carries unpredictable immune-related side effects, highlighting the need for careful management in clinical practice.
