Nivolumab Outperforms Brentuximab Vedotin in Treating Hodgkin’s Lymphoma
A recent study published in the New England Journal of Medicine highlights a significant breakthrough in the treatment of advanced-stage Hodgkin’s lymphoma, demonstrating that a nivolumab-based regimen outperforms the traditional brentuximab vedotin therapy. This important 2-year progression-free survival (PFS) data, spearheaded by Dr. Jonathan W. Friedberg from the University of Rochester Wilmot Cancer Institute, presents a strong case for reevaluating treatment options for patients aged 12 and older with stage III or IV classic Hodgkin’s lymphoma.
Study Overview
The phase III, multicenter, randomized trial, known as SWOG S1826, involved 970 patients aged 12 and up, with newly diagnosed stage III or IV classic Hodgkin’s lymphoma. The study compared two groups: one receiving nivolumab combined with AVD (doxorubicin, vinblastine, and dacarbazine) and the other receiving brentuximab vedotin paired with AVD. The results were compelling, with two-year PFS rates showing 92% for the nivolumab regimen compared to 83% for the brentuximab vedotin regimen, yielding a hazard ratio of 0.45 (95% CI 0.30-0.65).
Promising New Treatment Paradigm
In light of these findings, Dr. Friedberg and his colleagues advocate for the nivolumab regimen as a primary treatment option. They note that it not only significantly improves PFS but also possesses an excellent safety profile, with fewer patients experiencing lasting side effects. Additionally, the potential for avoiding toxic consolidative radiation therapies and lowering drug-acquisition and supportive-care costs makes this regimen highly attractive for both patients and healthcare providers.
Dr. James O. Armitage from the University of Nebraska School of Medicine and Dr. Dan L. Longo from Brigham and Women’s Hospital echoed the potential implications of this study, stating that the successful incorporation of brentuximab vedotin has led many to assume that further improvements in treatment were unlikely. However, they assert that the results from SWOG S1826 challenge this perspective, indicating a possible shift towards nivolumab being the treatment of choice across all stages of Hodgkin’s lymphoma.
Age Considerations in Hodgkin’s Lymphoma Treatment
The study significantly included older patients, a demographic often underrepresented in clinical trials for Hodgkin’s lymphoma. The 2-year PFS rates for this group were also promising, with 88% for nivolumab versus 65% for brentuximab vedotin (HR 0.30, 95% CI 0.12-0.72). Adolescent patients also showed favorable outcomes, reinforcing the versatility and efficacy of the nivolumab regimen.
Safety and Tolerability
When considering safety, the nivolumab group also demonstrated a lower rate of treatment discontinuation (7.6%) compared to the brentuximab vedotin group (12%). Notably, fewer patients received end-of-treatment radiotherapy, highlighting a move away from radiation therapy in adolescents receiving the nivolumab-based regimen.
While certain adverse effects like neutropenia were more common in those receiving the nivolumab treatment (56% vs. 34% for brentuximab vedotin), the data showed that high-grade adverse events were generally more frequent in the brentuximab group.
The Future of Hodgkin’s Lymphoma Treatments
The promising outcomes of this trial suggest that nivolumab, in combination with AVD, represents an important new treatment option for Hodgkin’s lymphoma patients, particularly for older individuals who may be more susceptible to treatment side effects.
These findings may shift the landscape of Hodgkin’s lymphoma treatment, providing a cost-effective, less toxic alternative that offers improved survival rates and quality of life for patients.
