Brentuximab vedotin in T-cell lymphoma
Expert Rev Hematol 2019 Jan;12(1):5-19.PMID:30526166DOI:10.1080/17474086.2019.1558399.
Brentuximab vedotin is an antibody-drug conjugate, which combines a CD30 monoclonal antibody with the microtubule-disrupting agent monomethylauristatin E. The utility of Brentuximab vedotin has been explored in a number of diseases, with a recent focus on T-cell lymphoma, particularly systemic anaplastic large-cell lymphoma (sALCL) and cutaneous T-cell lymphoma (CTCL), as well as other peripheral T-cell lymphoma (PTCL) histologies. Areas covered: This review surveys current data on the efficacy of Brentuximab vedotin in T-cell lymphoma, as well as embedding it in a therapeutic context by reviewing potential competitor agents in the clinic. Data are drawn from published literature, with a focus on clinical trial data rather than preclinical studies or case reports. Expert opinion: Brentuximab vedotin has a clear clinical benefit in CTCL and sALCL, and can achieve durable responses in a number of patients. Toxicities, particularly peripheral neuropathy, may limit treatment in some patients; however, the agent is generally well tolerated. In this context, Brentuximab vedotin has been globally approved for use in sALCL and certain CTCL subtypes, however, further information is required to enhance our understanding of when and in whom to best employ this agent, as well as exploring rational combinations to augment responses.
Pembrolizumab versus Brentuximab vedotin in relapsed or refractory classical Hodgkin lymphoma (KEYNOTE-204): an interim analysis of a multicentre, randomised, open-label, phase 3 study
Lancet Oncol 2021 Apr;22(4):512-524.PMID:33721562DOI:10.1016/S1470-2045(21)00005-X.
Background: PD-1 blockade via pembrolizumab monotherapy has shown antitumour activity and toxicity in patients with relapsed or refractory classical Hodgkin lymphoma. Here, we present interim analyses from the KEYNOTE-204 study evaluating pembrolizumab versus Brentuximab vedotin for relapsed or refractory classical Hodgkin lymphoma. Methods: In this randomised, open-label, phase 3 study, patients aged 18 years or older with relapsed or refractory classical Hodgkin lymphoma with measurable disease and an Eastern Cooperative Oncology Group performance status of 0 or 1 who were ineligible for or had relapsed after autologous haematopoietic stem-cell transplantation (HSCT) were enrolled at 78 hospitals and cancer centres in 20 countries and territories. Patients were randomly assigned (1:1) with an interactive voice response system to pembrolizumab 200 mg intravenously every 3 weeks or Brentuximab vedotin 1·8 mg/kg intravenously every 3 weeks. Randomisation was stratified by previous autologous HSCT and status after front-line therapy. Results from the second interim analysis are presented here, with a database cutoff of Jan 16, 2020. The dual primary endpoints assessed in the intention-to-treat population were progression-free survival as assessed by blinded independent central review, and overall survival (not analysed at this interim analysis). Safety was assessed in all patients who received at least one dose of the study drug. This study is registered with ClinicalTrials.gov, NCT02684292. Recruitment for this trial is closed. Findings: Between July 8, 2016, and July 13, 2018, 151 patients were randomly assigned to pembrolizumab and 153 to Brentuximab vedotin. After a median time from randomisation to data cutoff of 25·7 months (IQR 23·4-33·0), median progression-free survival was 13·2 months (95% CI 10·9-19·4) for pembrolizumab versus 8·3 months (5·7-8·8) for Brentuximab vedotin (hazard ratio 0·65 [95% CI 0·48-0·88]; p=0·0027). The most common grade 3-5 treatment-related adverse events were pneumonitis (six [4%] of 148 patients in the pembrolizumab group vs one [1%] of 152 patients in the Brentuximab vedotin group), neutropenia (three [2%] vs 11 [7%]), decreased neutrophil count (one [1%] vs seven [5%]), and peripheral neuropathy (one [1%] vs five [3%]). Serious treatment-related adverse events occurred in 24 (16%) of 148 patients receiving pembrolizumab and 16 (11%) of 152 patients receiving Brentuximab vedotin. One treatment-related death due to pneumonia occurred in the pembrolizumab group. Interpretation: Pembrolizumab showed statistically significant and clinically meaningful improvement in progression-free survival compared with Brentuximab vedotin, with safety consistent with previous reports. These data support pembrolizumab as the preferred treatment option for patients with relapsed or refractory classical Hodgkin lymphoma who have relapsed post-autologous HSCT or are ineligible for autologous HSCT.

Brentuximab Vedotin with Chemotherapy in Pediatric High-Risk Hodgkin's Lymphoma
N Engl J Med 2022 Nov 3;387(18):1649-1660.PMID:PMC9945772DOI:10.1056/NEJMoa2206660.
Background: In adults with advanced-stage Hodgkin's lymphoma, the CD30-directed antibody-drug conjugate Brentuximab vedotin combined with multiagent chemotherapy has been shown to have greater efficacy, but also more toxic effects, than chemotherapy alone. The efficacy of this targeted therapy approach in children and adolescents with Hodgkin's lymphoma is unclear. Methods: We conducted an open-label, multicenter, randomized, phase 3 trial involving patients 2 to 21 years of age with previously untreated Hodgkin's lymphoma of stage IIB with bulk tumor or stage IIIB, IVA, or IVB. Patients were assigned to receive five 21-day cycles of Brentuximab vedotin with doxorubicin, vincristine, etoposide, prednisone, and cyclophosphamide (Brentuximab vedotin group) or the standard pediatric regimen of doxorubicin, bleomycin, vincristine, etoposide, prednisone, and cyclophosphamide (standard-care group). Slow-responding lesions, defined by a score of 4 or 5 (on a 5-point scale, with scores of 1 to 3 indicating rapid-responding lesions), were identified on centrally reviewed positron-emission tomography-computed tomography after two cycles. Involved-site radiation therapy was administered after the fifth cycle of therapy to slow-responding lesions and to large mediastinal adenopathy that was present at diagnosis. The primary end point was event-free survival, defined as the time until disease progression occurred, relapse occurred, a second malignant neoplasm developed, or the patient died. Safety and overall survival were assessed. Results: Of 600 patients who were enrolled across 153 institutions, 587 were eligible. At a median follow-up of 42.1 months (range, 0.1 to 80.9), the 3-year event-free survival was 92.1% (95% confidence interval [CI], 88.4 to 94.7) in the Brentuximab vedotin group, as compared with 82.5% (95% CI, 77.4 to 86.5) in the standard-care group (hazard ratio for event or death, 0.41; 95% CI, 0.25 to 0.67; P<0.001). The percentage of patients who received involved-site radiation therapy did not differ substantially between the Brentuximab vedotin group and the standard-care group (53.4% and 56.8%, respectively). Toxic effects were similar in the two groups. Overall survival at 3 years was 99.3% (95% CI, 97.3 to 99.8) in the Brentuximab vedotin group and 98.5% (95% CI, 96.0 to 99.4) in the standard-care group. Conclusions: The addition of Brentuximab vedotin to standard chemotherapy resulted in superior efficacy, with a 59% lower risk of an event or death, and no increase in the incidence of toxic effects at 3 years.

Brentuximab vedotin as consolidation therapy after autologous stem-cell transplantation in patients with Hodgkin's lymphoma at risk of relapse or progression (AETHERA): a randomised, double-blind, placebo-controlled, phase 3 trial
Lancet 2015 May 9;385(9980):1853-62.PMID:25796459DOI:10.1016/S0140-6736(15)60165-9.
Background: High-dose therapy followed by autologous stem-cell transplantation is standard of care for patients with relapsed or primary refractory Hodgkin's lymphoma. Roughly 50% of patients might be cured after autologous stem-cell transplantation; however, most patients with unfavourable risk factors progress after transplantation. We aimed to assess whether Brentuximab vedotin improves progression-free survival when given as early consolidation after autologous stem-cell transplantation. Methods: We did this randomised, double-blind, placebo-controlled, phase 3 trial at 78 sites in North America and Europe. Patients with unfavourable-risk relapsed or primary refractory classic Hodgkin's lymphoma who had undergone autologous stem-cell transplantation were randomly assigned, by fixed-block randomisation with a computer-generated random number sequence, to receive 16 cycles of 1·8 mg/kg Brentuximab vedotin or placebo intravenously every 3 weeks, starting 30-45 days after transplantation. Randomisation was stratified by best clinical response after completion of salvage chemotherapy (complete response vs partial response vs stable disease) and primary refractory Hodgkin's lymphoma versus relapsed disease less than 12 months after completion of frontline therapy versus relapse 12 months or more after treatment completion. Patients and study investigators were masked to treatment assignment. The primary endpoint was progression-free survival by independent review, defined as the time from randomisation to the first documentation of tumour progression or death. Analysis was by intention to treat. This trial is registered with ClinicalTrials.gov, number NCT01100502. Findings: Between April 6, 2010, and Sept 21, 2012, we randomly assigned 329 patients to the Brentuximab vedotin group (n=165) or the placebo group (n=164). Progression-free survival by independent review was significantly improved in patients in the Brentuximab vedotin group compared with those in the placebo group (hazard ratio [HR] 0·57, 95% CI 0·40-0·81; p=0·0013). Median progression-free survival by independent review was 42·9 months (95% CI 30·4-42·9) for patients in the Brentuximab vedotin group compared with 24·1 months (11·5-not estimable) for those in the placebo group. We recorded consistent benefit (HR <1) of Brentuximab vedotin consolidation across subgroups. The most frequent adverse events in the Brentuximab vedotin group were peripheral sensory neuropathy (94 [56%] of 167 patients vs 25 [16%] of 160 patients in the placebo group) and neutropenia (58 [35%] vs 19 [12%] patients). At time of analysis, 28 (17%) of 167 patients had died in the Brentuximab vedotin group compared with 25 (16%) of 160 patients in the placebo group. Interpretation: Early consolidation with Brentuximab vedotin after autologous stem-cell transplantation improved progression-free survival in patients with Hodgkin's lymphoma with risk factors for relapse or progression after transplantation. This treatment provides an important therapeutic option for patients undergoing autologous stem-cell transplantation. Funding: Seattle Genetics and Takeda Pharmaceuticals International.
Brentuximab Vedotin: A Review in CD30-Positive Hodgkin Lymphoma
Drugs 2017 Mar;77(4):435-445.PMID:28190142DOI:10.1007/s40265-017-0705-5.
Intravenous Brentuximab vedotin (ADCETRIS®) is a targeted antibody-drug conjugate (ADC) active against CD30-positive cancer cells such as those associated with classical Hodgkin lymphoma (HL). In noncomparative, phase 2 trials and in the real-world setting, salvage therapy with Brentuximab vedotin resulted in high objective response (complete plus partial remission) rates in patients with relapsed or refractory CD30-positive HL, including as retreatment in patients who had an objective response to previous Brentuximab vedotin therapy and subsequently relapsed. These beneficial outcomes were durable during long-term follow-up. As consolidation therapy after autologous haematopoietic stem cell transplant (ASCT) in the multinational, phase 3 AETHERA trial, Brentuximab vedotin prolonged progression-free-survival (PFS) compared with placebo at a median follow-up of 30 months (primary analysis), with a 43% reduction in the risk of disease progression or death. The beneficial effects of Brentuximab vedotin consolidation therapy were maintained during long-term follow-up. In the clinical trial and real-world setting, Brentuximab vedotin had an acceptable tolerability and safety profile, with most adverse events manageable with dose reductions and/or delays [including peripheral sensory neuropathy (PSN) and neutropenia]. With a paucity of treatments available for many patients with relapsed or refractory HL, Brentuximab vedotin represents an important option for the management of patients who have failed high-dose chemotherapy/ASCT or at least two prior chemotherapy regimens and as post-ASCT consolidation therapy in patients who are at increased risk/high-risk of relapse or progression after ASCT.
