Brentuximab vedotin (BV), a potent antibody-drug conjugate, targets the CD30 antigen. Owing to the remarkable efficacy shown in CD30-positive lymphomas, such as Hodgkin's lymphoma and systemic anaplastic large-cell lymphoma, BV was granted accelerated approval in 2011 by the US Food and Drug Administration. Thereafter, many large-scale trials in various situations have been performed, which led to extensions of the original indication. The aim of this review was to describe the latest updates on ...[more]

Project description:Brentuximab vedotin (SGN-35; Adcetris®) is an anti-CD30 antibody conjugated via a protease-cleavable linker to the potent anti-microtubule agent monomethyl auristatin E (MMAE). Following binding to CD30, brentuximab vedotin is rapidly internalized and transported to lysosomes where MMAE is released and binds to tubulin, leading to cell cycle arrest and apoptosis. Several trials have shown durable antitumor activity with a manageable safety profile in patients with relapsed/refractory Hodgkin lymphoma, systemic anaplastic large cell lymphoma, or primary cutaneous CD30-positive lymphoproliferative disorders. Peripheral sensory neuropathy is a significant adverse event associated with brentuximab vedotin administration. Neuropathy symptoms are cumulative and dose-related. Multiple ongoing trials are currently evaluating brentuximab vedotin alone or in combination with other agents in relapsed/refractory patients, as well as patients with newly diagnosed disease.

Project description:Monoclonal antibodies (mAb) have become an effective treatment strategy for hematologic malignancies. CD30 is a rational target for therapy due to its limited expression on normal tissues and the strong and uniform expression on malignant cells in classical Hodgkin's lymphoma (cHL) and anaplastic large-cell lymphoma (ALCL). Brentuximab vedotin, an anti-CD30 antibody-drug conjugate, utilizes the targeting properties of mAb to deliver a cytotoxic agent inside the malignant cell. Brentuximab vedotin has significant clinical activity in patients with relapsed or refractory cHL and relapsed or refractory ALCL, and has the potential to represent a significant advance in modern oncology.

Project description: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.

Project description:The arrival of the CD30 directed antibody-drug conjugate, brentuximab vedotin (BV), has altered the approach to patients with classical Hodgkin lymphoma. Since initial approval in 2011, BV has been extensively studied in previously untreated and relapsed/refractory patients. Treatment indications for the antibody-drug conjugate have been expanded from the previously treated population to include maintenance therapy after autologous stem cell transplantation and recently, combination with chemotherapy in newly diagnosed advanced stage patients. This article will review the evolution of BV in classical Hodgkin lymphoma, detailing the studies that led to the approved indications and discussion of recent trials in combination with chemotherapy and immunotherapy.

Project description:Brentuximab vedotin (BV) is an antibody-drug conjucate (ADC) comprising a CD30-directed antibody, conjugated to the microtubule-disrupting agent MMAE via a protease cleavable linker. BV is FDA approved for use in relapsed classical Hodgkin lymphoma (HL) and relapsed systemic anaplastic large cell lymphoma (sALCL). There are multiple publications for its utility in other malignancies such as diffuse large B-cell lymphoma (DLBCL), mycosis fungoides (MF), Sézary syndrome (SS), T-cell lymphomas (TCL), primary mediastinal lymphoma (PMBL), and post-transplant lymphoproliferative disorders (PTLD). We believe that BV could potentially provide a strong additional treatment option for patients suffering from NHL.Perform a systematic review on the use of BV in non-Hodgkin lymphoma (NHL) and other CD30+ malignancies in humans.We searched various databases including PubMed (1946-2015), EMBASE (1947-2015), and Cochrane Central Register of Controlled Trials (1898-2015).Inclusion criteria specified all studies and case reports of NHLs in which BV therapy was administered.A total of 28 articles met these criteria and are summarized in this manuscript.Our findings indicate that BV induces a variety of responses, largely positive in nature and variable between NHL subtypes. With additional, properly powered prospective studies, BV may prove to be a strong candidate in the treatment of various CD30+ malignancies.

Project description:Classical Hodgkin lymphoma (HL) relapses after or is refractory to upfront multiagent chemotherapy in 20%-30% of patients. Effective salvage therapy for relapsed or refractory HL is limited, and advancements are needed. Brentuximab vedotin (BV), an anti-CD30 antibody-drug conjugate, has demonstrated significant activity and manageable toxicities in advanced HL. Currently approved as a monotherapy for patients with HL that is relapsed or refractory to multiple lines of chemotherapy or autologous stem cell transplantation, BV is now being evaluated earlier in the course of disease and in combination with other therapies. This review discusses the successful translation of BV from its conception to the clinical setting and highlights ongoing trials that may ultimately expand its role in relapsed or refractory HL and improve outcomes for patients.

Project description:Brentuximab vedotin (BV) is an effective and well-tolerated treatment for patients with classical Hodgkin lymphoma (HL). It was initially approved by the US FDA for the treatment of HL after failure of autologous hematopoietic stem cell transplant (autoHSCT) or after failure of at least two prior lines of multiagent chemotherapy in patients who are not transplant candidates, and then subsequently, as consolidation therapy after autoHSCT in patients who are at high risk for relapse. However, the role of BV in the treatment of HL is evolving. BV has shown promising efficacy as a salvage treatment in the second-line setting prior to autoHSCT. Most recently, the ECHELON-1 trial demonstrated that BV combined with AVD for the treatment of newly diagnosed advanced stage HL improved modified progression-free survival (mPFS) compared with standard ABVD. Based on these results, the US FDA has approved BV as part of the initial treatment of advanced stage HL. With the approval of BV as front-line therapy, depending on how widely the use of BV plus AVD is adopted, the role of BV in the treatment of patients with relapsed or refractory (rel/ref) HL may need to be redefined. BV retreatment can be effective, and studies of rational BV-based combination regimens may help to improve response rates and overcome BV resistance. Furthermore, BV has been demonstrated to be effective in the initial treatment of elderly or unfit patients, and ongoing studies are evaluating the addition of BV to initial chemotherapy in patients with early stage HL.

Project description:The expression of CD30 receptors is one of the defining characteristics of the malignant Reed-Sternberg cells of Hodgkin lymphoma (HL). CD30 is rarely expressed by normal cells and is rapidly internalized, making it an ideal therapeutic target for monoclonal antibodies and for antibody-drug conjugates. Brentuximab vedotin is the first antibody-drug conjugate to be approved by regulatory agencies for the treatment of patients with relapsed HL, with a single-agent response rate of 75%. In this review article, we discuss the current and ongoing development of brentuximab vedotin in patients with relapsed and newly diagnosed HL.

Project description:BACKGROUND:Brentuximab vedotin is an anti-CD30 antibody-drug conjugate that has been approved for relapsed and refractory Hodgkin's lymphoma. METHODS:We conducted an open-label, multicenter, randomized phase 3 trial involving patients with previously untreated stage III or IV classic Hodgkin's lymphoma, in which 664 were assigned to receive brentuximab vedotin, doxorubicin, vinblastine, and dacarbazine (A+AVD) and 670 were assigned to receive doxorubicin, bleomycin, vinblastine, and dacarbazine (ABVD). The primary end point was modified progression-free survival (the time to progression, death, or noncomplete response and use of subsequent anticancer therapy) as adjudicated by an independent review committee. The key secondary end point was overall survival. RESULTS:At a median follow-up of 24.6 months, 2-year modified progression-free survival rates in the A+AVD and ABVD groups were 82.1% (95% confidence interval [CI], 78.8 to 85.0) and 77.2% (95% CI, 73.7 to 80.4), respectively, a difference of 4.9 percentage points (hazard ratio for an event of progression, death, or modified progression, 0.77; 95% CI, 0.60 to 0.98; P=0.04). There were 28 deaths with A+AVD and 39 with ABVD (hazard ratio for interim overall survival, 0.73 [95% CI, 0.45 to 1.18]; P=0.20) [corrected]. All secondary efficacy end points trended in favor of A+AVD. Neutropenia occurred in 58% of the patients receiving A+AVD and in 45% of those receiving ABVD; in the A+AVD group, the rate of febrile neutropenia was lower among the 83 patients who received primary prophylaxis with granulocyte colony-stimulating factor than among those who did not (11% vs. 21%). Peripheral neuropathy occurred in 67% of patients in the A+AVD group and in 43% of patients in the ABVD group; 67% of patients in the A+AVD group who had peripheral neuropathy had resolution or improvement at the last follow-up visit. Pulmonary toxicity of grade 3 or higher was reported in less than 1% of patients receiving A+AVD and in 3% of those receiving ABVD. Among the deaths that occurred during treatment, 7 of 9 in the A+AVD group were associated with neutropenia and 11 of 13 in the ABVD group were associated with pulmonary-related toxicity. CONCLUSIONS:A+AVD had superior efficacy to ABVD in the treatment of patients with advanced-stage Hodgkin's lymphoma, with a 4.9 percentage-point lower combined risk of progression, death, or noncomplete response and use of subsequent anticancer therapy at 2 years.
