Intensified systemic chemotherapy has the highest primary cure rate for advanced-stage, classical Hodgkin lymphoma but this comes with a cost of severe and potentially life long, persisting toxicities. With the new regimen of brentuximab vedotin, etoposide, cyclophosphamide, doxorubicin, dacarbazine, and dexamethasone (BrECADD), we aimed to improve the risk-to-benefit ratio of treatment of advanced-stage, classical Hodgkin lymphoma guided by PET after two cycles. This randomised, multicentre, parallel, open-label, phase 3 trial was done in 233 trial sites across nine countries. Eligible patients were adults (aged ≤60 years) with newly diagnosed, advanced-stage, classical Hodgkin lymphoma (ie, Ann Arbor stage III/IV, stage II with B symptoms, and either one or both risk factors of large mediastinal mass and extranodal lesions). Patients were randomly assigned (1:1) to four or six cycles (21-day intervals) of escalated doses of etoposide (200 mg/m2 intravenously on days 1–3), doxorubicin (35 mg/m2 intravenously on day 1), and cyclophosphamide (1250 mg/m2 intravenously on day 1), and standard doses of bleomycin (10 mg/m2 intravenously on day 8), vincristine (1·4 mg/m2 intravenously on day 8), procarbazine (100 mg/m2 orally on days 1–7), and prednisone (40 mg/m2 orally on days 1–14; eBEACOPP) or BrECADD, guided by PET after two cycles. Patients and investigators were not masked to treatment assignment. Hierarchical coprimary objectives were to show (1) improved tolerability defined by treatment-related morbidity and (2) non-inferior efficacy defined by progression-free survival with an absolute non-inferiority margin of 6 percentage points of BrECADD compared with eBEACOPP. An additional test of superiority of progression-free survival was to be done if non-inferiority had been established. Analyses were done by intention to treat; the treatment-related morbidity assessment required documentation of at least one chemotherapy cycle. This trial was registered at ClinicalTrials.gov (NCT02661503). Between July 22, 2016, and Aug 27, 2020, 1500 patients were enrolled, of whom 749 were randomly assigned to BrECADD and 751 to eBEACOPP. 1482 patients were included in the intention-to-treat analysis. The median age of patients was 31 years (IQR 24–42). 838 (56%) of 1482 patients were male and 644 (44%) were female. Most patients were White (1352 [91%] of 1482). Treatment-related morbidity was significantly lower with BrECADD (312 [42%] of 738 patients) than with eBEACOPP (430 [59%] of 732 patients; relative risk 0·72 [95% CI 0·65–0·80]; p<0·0001). At a median follow-up of 48 months, BrECADD improved progression-free survival with a hazard ratio of 0·66 (0·45–0·97; p=0·035); 4-year progression-free survival estimates were 94·3% (95% CI 92·6–96·1) for BrECADD and 90·9% (88·7–93·1) for eBEACOPP. 4-year overall survival rates were 98·6% (97·7–99·5) and 98·2% (97·2–99·3), respectively. BrECADD guided by PET after two cycles is better tolerated and more effective than eBEACOPP in first-line treatment of adult patients with advanced-stage, classical Hodgkin lymphoma.

Background Treatment with ABVD (doxorubicin, bleomycin, vinblastine, and dacarbazine) is a well-established therapy for advanced Hodgkin’s lymphoma (HL). However, the recently completed ECHELON-1 trial showed potential net clinical benefit for brentuximab vedotin (BREN+AVD) compared to ABVD as frontline therapy in patients with advanced Hodgkin’s lymphoma. The objective of this analysis is to determine whether, on current evidence, BREN+AVD is cost-effective relative to ABVD as frontline therapy in patients with advanced HL. Methods We constructed a probabilistic Markov model with two arms and six mutually exclusive health states, using six-month cycle lengths, and a 15-year time horizon. Time-dependent transition probabilities were calculated from ‘real-world’ data collected by the BC Cancer’s Centre for Lymphoid Cancer database or from the literature for ABVD. Time-dependent transition probabilities for BREN+AVD were taken from the ECHELON-1 trial. We estimated the incremental cost and effects per patient of each therapy and calculated the incremental cost-effectiveness ratio (ICER). Costs were measured in 2018 Canadian dollars and effects measured in quality-adjusted life years (QALYs). A probabilistic analysis was used to generate a cost-effectiveness acceptability curve (CEAC). Results The incremental cost between standard therapy with ABVD and therapy with BREN+AVD was estimated to be $192,336. The regimen of BREN+AVD resulted in a small benefit in terms of QALYs (0.46 QALYs). The estimated ICER was $418,122 per QALY gained. The probabilistic analysis suggests very few (8%) simulations fall below $100,000 per QALY. Even at a threshold of $200,000 per QALY gained, there was only a 24% chance that BREN+AVD would be considered cost-effective. Sensitivity analyses evaluating price reductions for brentuximab showed that these reductions needed to be in excess of 70% for this regimen to be cost-effective at a threshold of $100,000 per QALY. Conclusions There may be a clinical benefit associated with BREN+AVD, but on current evidence the benefit is not adequately substantive compared to ABVD therapy given the cost of brentuximab vedotin. Agencies responsible for making decisions about BREN+AVD as frontline therapy for patients with advanced HL should consider whether they are willing to implement this treatment given the current uncertainty and cost-benefit profile, or negotiate substantial price-reductions from the manufacturer should they choose to reimburse.

Among 15 patients with relapsed ALCL after the failure of brentuximab vedotin therapy, the ALK inhibitor brigatinib led to a complete response in 73%, and progression-free survival at 2 years was 73%.

SummaryPurpose Brentuximab vedotin (BV) is an anti-CD30 antibody-drug conjugate used in the treatment of several types of lymphomas. Expression of the target antigen has also been reported on a variety of malignant tumors of nonlymphoid origin. This phase 2, open-label study evaluated the safety and antitumor activity of BV in patients with CD30-expressing nonlymphomatous malignancies. Methods Patients were dosed with 1.8 or 2.4 mg/kg BV once every three weeks. Antitumor activity was assessed at Cycles 2, 4, and every 4 cycles thereafter. Patients with stable disease or better were eligible to continue treatment until disease progression, unacceptable toxicity, or study closure. Results Of the 2693 patients screened, 3.8% had solid tumors with CD30 expression and 63 eligible patients with solid tumors enrolled in this study. The most common CD30 positive solid tumors were testicular cancer and mesothelioma. Both subtypes had more than one patient with an objective response. The median duration of BV exposure was 6.1 weeks. The disease control rate, defined as achieving stable disease or better at any point during the study, was 55%. The objective response rate was 11%, with a median duration of response of 2.92 months. The most common adverse events reported were fatigue (57%), nausea (33%), and decreased appetite (32%). Conclusion The safety profile of BV in patients with solid tumors was similar to the known safety profile of BV. In solid tumors, BV had modest activity as a single agent, which was similar to other second-line treatments already available to patients.

CD30 is overexpressed in several lymphoma types, including classic Hodgkin lymphoma (cHL), some peripheral T-cell lymphomas (PTCL), and some cutaneous T-cell lymphomas. The antibody–drug conjugate brentuximab vedotin targets CD30-positive cells and has been evaluated for the treatment of various lymphoma entities. This narrative review summarizes 10 years of experience with brentuximab vedotin for the treatment of CD30-positive lymphomas, discusses novel therapies targeting CD30 in development, and highlights remaining controversies relating to CD30-targeted therapy across lymphoma types. The collective body of evidence for brentuximab vedotin demonstrates that exploitation of CD30 can provide sustained benefits across a range of different CD30-positive lymphomas, in both clinical trials and real-world settings. Preliminary experience with brentuximab vedotin in combination with immune checkpoint inhibitors for relapsed/refractory cHL is encouraging, but further exploration is required. The optimal use of brentuximab vedotin for first-line therapy of PTCL remains to be determined. Further research is required on brentuximab vedotin treatment in high-risk patient populations, and in rare lymphoma subtypes, for which no standard of care exists. Novel therapies targeting CD30 include chimeric antigen receptor therapies and bispecific antibody T-cell engagers, which may be expected to further improve outcomes for patients with CD30-positive lymphomas in the coming years.

To evaluate the efficacy and safety of brentuximab vedotin (BV) combined with a CHP-like regimen (cyclophosphamide, doxorubicin, and prednisone) as first-line treatment for newly diagnosed peripheral T-cell lymphoma (PTCL). We retrospectively analyzed the clinical data of patients with PTCL who received BV in combination with a CHP-like regimen as first-line therapy between January 2021 and October 2023. Fifty patients were included in this study, with a median age of 57 years (rang, 22–86 years). The median number of BV cycles administered was six (range, 2–8 cycles). After a median follow-up of 35.2 months (95% confidence interval [CI], 30.9–39.5), the overall response rate (ORR) was 80%, with 44% of the patients achieving a complete response (CR). In patients with the ALK-positive anaplastic large cell lymphoma (ALCL) subtype, the CR rate was 70.6%. The median progression-free survival (PFS) was 39.7 months (95% CI, 14.7-NA), whereas the median overall survival (OS) was not reached (the 1-year OS rate, 90%). Multivariate analysis indicated that bone marrow infiltration at diagnosis was the only factor that was significantly associated with poor OS. Neutropenia (81.3%) was the most common adverse event, and peripheral neuropathy was observed in 16.7% of patients. This real-world study suggests that BV combined with a CHP-like regimen is an effective and safe first-line treatment for patients with newly diagnosed PTCL.

Brentuximab vedotin (BV) has been increasingly used in the treatment of CD30-positive lymphomas since its approval in China in 2020. We aimed to evaluate the effectiveness and safety of BV-based regimens in a real-world setting with a larger cohort and longer follow-up period from a 2022 study. This multi-center, retrospective study included patients diagnosed with lymphoma treated with BV-based regimens between August 2020 and April 2025 at three real-world centers in central China. A total of 252 CD30-positive lymphoma patients were collected: 44.8% were cHL, 27.4% were sALCL and 27.8% were other types of lymphoma, who accomplished a median of 4 cycles of BV-based therapy. Effectiveness analysis was performed on 234 patients, revealing an overall response rate (ORR) of 67.1% and a complete response (CR) rate of 39.7%. After a median follow-up of 17.6 months (range: 0.1-55.6 months), the 1-year, 2-year and 3-year progression-free survival (PFS) rates were 72.7%, 69.4% and 69.4%, respectively, while the 1-year, 2-year and 3-year overall survival (OS) rates were 87.0%, 83.7% and 83.7%, respectively. First-line BV-based treatment yielded significantly better CR rates, although no significant survival advantage was observed after adjustment for confounding factors. The overall incidence of adverse events (AEs) of any grade was 85.7%, with the most frequently reported AEs being anemia, leukopenia, and infections. A total of 44 patients underwent stem cell transplantation (SCT), with 31 patients receiving BV-based bridge therapy and 10 patients receiving BV as consolidation therapy following SCT. Our findings further solidify the role of BV as an efficacious and generally well-tolerated treatment in CD30-positive lymphomas. Its clinical activity was observed across first-line, bridging, and post-SCT settings. However, given the heterogeneous lymphoma subtypes and treatment settings included in this real-world cohort, further prospective studies are warranted.

PurposePeripheral T-cell lymphoma (PTCL) is an aggressive disease with a poor prognosis. Brentuximab vedotin (BV), an anti-CD30 monoclonal antibody linked to a microtubule-disrupting agent, has been approved for the treatment of PTCL. We evaluated a new effective combination partner of BV using non-clinical approaches that could potentially identify agents capable of improving survival times for patients with PTCL.MethodsA high-throughput screening test was used to select the most synergistic partner of BV from 14 candidate drugs that were under development or available in clinical practice for PTCL. HH cells, originating from an aggressive cutaneous T-cell lymphoma, were used as an experimental model of PTCL. Apoptotic effects of the synergistic partner of BV were further investigated in vitro and in vivo using HH-cell xenograft mice.ResultsChidamide (tucidinostat), a novel histone deacetylase inhibitor, was found to have the greatest synergistic effect with BV on HH cells. The combined effects of chidamide and BV were demonstrated in a study of HH-cell xenograft mice; mean tumor size following combined treatment was 22% of that observed in the control group, compared with 71% and 58% following chidamide and BV monotherapy, respectively. Further investigations in vitro and in vivo revealed that the levels of an anti-apoptotic protein, Bcl-2, and a rate-limiting factor of DNA replication, CDC45, were reduced in HH cells treated with chidamide combined with BV compared with the control group.ConclusionThe use of chidamide in conjunction with BV may positively affect and enhance T-cellular apoptotic pathways without offsetting each other.
