In Vitro
In an in vitro model mimicking GCT of heterogeneous histology, Brentuximab vedotin abrogates cell viability of CD30-positive GCT27 EC line exerting marked time-dependent antiproliferative and pro-apoptotic activity. CD30-negative JAR cultured alone barely responds to brentuximab vedotin, while in coculture with GCT27 brentuximab vedotin induces clear dose-dependent cytotoxicity. Cellular proliferation and cell death are significantly enhanced in CD30-negative JAR cocultured with CD30-positive GCT27 compared to JAR cultured alone in proof of substantial bystander activity of brentuximab vedotin in CD30-negative GCT.
In Vivo
In vivo brentuximab vedotin promoted tumor regression and prolonged survival of mice bearing previously reported UM-PEL-1 tumors as well as UM-PEL-3 tumors derived from a newly established and characterized Kaposi's sarcoma-associated herpesvirus- and Epstein-Barr virus-positive PEL cell line.

1. Brentuximab vedotin in T-cell lymphoma
James Whisstock, H Miles Prince, Michael Dickinson, Carrie Van Der Weyden Expert Rev Hematol . 2019 Jan;12(1):5-19. doi: 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.

This phase 1-2 study evaluated brentuximab vedotin (BV) combined with nivolumab (Nivo) as first salvage therapy in patients with relapsed/refractory (r/r) classical Hodgkin lymphoma (cHL). In parts 1 and 2, patients received staggered dosing of BV and Nivo in cycle 1, followed by same-day dosing in cycles 2 to 4. In part 3, both study drugs were dosed, same day, for all 4 cycles. At end of study treatment, patients could undergo autologous stem cell transplantation (ASCT) per investigator discretion. The objective response rate (ORR; N = 91) was 85%, with 67% achieving a complete response (CR). At a median follow-up of 34.3 months, the estimated progression-free survival (PFS) rate at 3 years was 77% (95% confidence interval [CI], 65% to 86%) and 91% (95% CI, 79% to 96%) for patients undergoing ASCT directly after study treatment. Overall survival at 3 years was 93% (95% CI, 85% to 97%). The most common adverse events (AEs) prior to ASCT were nausea (52%) and infusion-related reactions (43%), all grade 1 or 2. A total of 16 patients (18%) had immune-related AEs that required systemic corticosteroid treatment. Peripheral blood immune signatures were consistent with an activated T-cell response. Median gene expression of CD30 in tumors was higher in patients who responded compared with those who did not. Longer-term follow-up of BV and Nivo as a first salvage regimen shows durable efficacy and impressive PFS, especially in patients who proceeded directly to transplant, without additional toxicity concerns. This trial was registered at as#NCT02572167.

Background:Despite advances in the treatment of Hodgkin lymphoma with the introduction of PET-adapted regimens, practical challenges prevent more widespread use of these approaches. The ECHELON-1 study assessed the safety and efficacy of front-line A+AVD (brentuximab vedotin, doxorubicin, vinblastine, and dacarbazine) versus ABVD (doxorubicin, bleomycin, vinblastine, and dacarbazine) in patients with stage III or IV classical Hodgkin lymphoma. The primary analysis showed improved modified progression-free survival with A+AVD. We present an updated analysis of ECHELON-1 at 5 years, an important landmark for this patient population.Methods:ECHELON-1 was an international, open-label, randomised, phase 3 trial done at 218 clinical sites, including hospitals, cancer centres, and community clinics, in 21 countries. Previously untreated patients (≥18 years with an Eastern Cooperative Oncology Group performance status of ≤2) with stage III or IV classical Hodgkin lymphoma were randomly assigned (1:1) to receive A+AVD (brentuximab vedotin, 1·2 mg/kg of bodyweight, doxorubicin 25 mg/m2of body surface area, vinblastine 6 mg/m2, and dacarbazine 375 mg/m2) or ABVD (doxorubicin 25 mg/m2, bleomycin 10 U/m2, vinblastine 6 mg/m2, and dacarbazine 375 mg/m2) intravenously on days 1 and 15 of each 28-day cycle for up to six cycles. Stratification factors included region (Americas vs Europe vs Asia) and International Prognostic Score risk group (low, intermediate, or high risk). The primary endpoint was modified progression-free survival; this 5-year update includes analysis of progression-free survival as per investigator assessment in the intention-to-treat population, which was an exploratory endpoint, although the 5-year analysis was not prespecified in the protocol. This trial is registered with (NCT01712490) and EudraCT (2011-005450-60), and is ongoing.Findings:Between Nov 19, 2012, and Jan 13, 2016, 1334 patients were randomly assigned to receive A+AVD (n=664) or ABVD (n=670). At a median follow-up of 60·9 months (IQR 52·2-67·3), 5-year progression-free survival was 82·2% (95% CI 79·0-85·0) with A+AVD and 75·3% (71·7-78·5) with ABVD (hazard ratio [HR] 0·68 [95% CI 0·53-0·87]; p=0·0017). Among PET-2-negative patients, 5-year progression-free survival was higher with A+AVD than with ABVD (84·9% [95% CI 81·7-87·6] vs 78·9% [75·2-82·1]; HR 0·66 [95% CI 0·50-0·88]; p=0·0035). 5-year progression-free survival for PET-2-positive patients was 60·6% (95% CI 45·0-73·1) with A+AVD versus 45·9% (32·7-58·2) with ABVD (HR 0·70 [95% CI 0·39-1·26]; p=0·23). Peripheral neuropathy continued to improve or resolve over time with both A+AVD (375 [85%] of 443 patients) and ABVD (245 [86%] of 286 patients); more patients had ongoing peripheral neuropathy in the A+AVD group (127 [19%] of 662) than in the ABVD group (59 [9%] of 659). Fewer secondary malignancies were reported with A+AVD (19 [3%] of 662) than with ABVD (29 [4%] of 659). More livebirths were reported in the A+AVD group (n=75) than in the ABVD group (n=50).Interpretation:With 5 years of follow-up, A+AVD showed robust and durable improvement in progression-free survival versus ABVD, regardless of PET-2 status, and a consistent safety profile. On the basis of these findings, A+AVD should be preferred over ABVD for patients with previously untreated stage III or IV classical Hodgkin lymphoma.Funding:Millennium Pharmaceuticals (a wholly owned subsidiary of Takeda Pharmaceutical Company), and Seagen.
