Abstract
BACKGROUND Post-transplant cyclophosphamide (PTCy) has emerged as a promising approach for preventing graft-versus-host disease (GVHD) in allogeneic hematopoietic stem cell transplantation (allo-HSCT). However, there is a lack of studies examining the impact of this GVHD prophylaxis when different donor types are used in patients with Hodgkin lymphoma (HL). OBJECTIVE To compare the outcomes of patients with HL undergoing HSCT from both HLA-matched donors, which include matched sibling donors (MSD) and matched unrelated donors (MUD), and haploidentical donors, using PTCy as GVHD prophylaxis approach in all cohorts. STUDY DESIGN We retrospectively compared transplant outcomes of allo-HSCT from 166 HLA-matched donors (96 siblings and 70 unrelated) and 694 haploidentical donors using PTCy-based GVHD prophylaxis in patients with HL registered in the EBMT database from 2010 to 2020. RESULTS Haploidentical transplantation showed significantly lower platelet engraftment (86% vs 94%, p<0.001) and higher rates of grades II-IV acute GVHD (24% vs 34%, p=0.01) compared to HLA-matched transplantation. The 2-year cumulative incidence of non-relapse mortality (NRM) was significantly lower in the HLA-matched cohort compared to haploidentical cohort (10% vs 18%, p=0.02), resulting in a higher overall survival (OS) rate (82% vs 70%, p=0.002). There were no significant differences observed in terms of relapse, progression-free survival, or GVHD-free relapse-free survival between the groups. In multivariable analysis, haploidentical transplantation was associated with an increased risk of grades II-IV acute GVHD, NRM, and worse OS compared to HLA-matched transplantation. CONCLUSIONS Our findings suggest that, in the context of PTCy-based GVHD prophylaxis, transplantation from HLA-matched donors appears to be a more favorable option compared to haploidentical transplantation.

Abstract
Hodgkin lymphoma (HL) patients who relapse after autologous-stem-cell- transplantation (auto-SCT) have traditionally had a poor prognosis. We analyzed 1781 adult HL patients who relapsed between 2006 and 2017 after a first auto-SCT. The 4-year overall survival (OS) after relapse continuously increased from 32% for patients relapsing in 2006-2008, to 63% for patients relapsing in 2015-2017 (p = 0.001). The improvement over time was predominantly noted in patients who had an early relapse (within 12 months) after auto-SCT (p = 0.01). On multivariate analysis, patients who relapsed in more recent years and those with a longer interval from transplant to relapse had a better OS, whereas increasing age, poor performance status, bulky disease, extranodal disease and presence of B symptoms at relapse were associated with a worse OS. Brentuximab vedotin (BV), checkpoint inhibitors (CPI) and second transplant (SCT2; 86% allogeneic) were used in 233, 91 and 330 patients respectively. The 4-year OS from BV, CPI, and SCT2 use was 55%, 48% and 55% respectively. In conclusion, the outcome after post-transplant relapse has improved significantly in recent years, particularly in the case of early relapse. These large-scale real-world data can serve as benchmark for future studies in this setting.

Abstract
We analysed long-term outcome of patients receiving haematopoietic allogeneic stem cell transplantation (allo-HSCT) as a first transplant for high-risk Hodgkin lymphoma (HL). One hundred and ninety patients were included in this study, 63% of them had previously received brentuximab vedotin and/or checkpoint inhibitors. Seventy patients (37%) received an unrelated donor allo-HSCT, 99 (51%) had myeloablative conditioning (MAC) and 60% had in?vivo T-cell/depleted grafts (TCD). The 100-day cumulative incidence (CI) of grade II-IV acute graft-versus-host disease (GVHD) was 25% and the 3-year CI of chronic GVHD was 38%. The 3-year CI of non-relapse mortality (NRM) and relapse rate were 21% and 38% respectively. After a median follow-up of 58?months, 3-year overall survival (OS) and progression-free survival (PFS) were 58% and 41% respectively. Multivariate analysis showed that, in comparison to reduced-intensity conditioning regimens with or without TCD, MAC using TCD had similar NRM and a lower risk of relapse leading to significantly better OS and PFS. MAC without TCD was associated with higher NRM and worse survival outcomes. These results suggest that in patients with high-risk HL and candidates of allo-HSCT, a MAC strategy with TCD might be the best option.

Abstract
Indications for autologous (auto-HCT) and allogeneic transplantation (allo-HCT) in relapsed/refractory Hodgkin lymphoma (rrHL) have been long established. The expectation is that long-term outcomes have significantly improved over time with increased experience in these procedures. The objective of this study was to assess whether this is the case and to identify further areas of improvement. A total of 13,639 adult patients receiving an auto-HCT or allo-HCT for rrHL were reported to the European Society for Blood and Marrow Transplantation (EBMT) over a 25-year period. Regarding auto-HCT, recipients are younger, interval between diagnosis and transplant shorter, peripheral blood has become the universal stem cell source and the use of total body irradiation is almost non-existent in recent years. Allo-HCT is currently mostly used as a second transplant; recipients are younger, fitter and less frequently, chemorefractory. Reduced intensity conditioning protocols have vastly replaced myeloablative protocols. Increasing numbers of haplo-HCT have been reported. Both in auto-HCT and allo-HCT, NRM, PFS and OS have significantly improved but relapse remains the main cause of treatment failure. A better selection of patients and improvements in the supportive care has resulted in a reduction in the NRM. Relapse after HCT remains unchanged and further research is needed.

Abstract
Autologous hematopoietic stem cell transplantation (ASCT) is curative for a proportion of patients with relapsed/refractory (R/R) Hodgkin lymphoma (HL). However, there is a small group of patients with high-risk of relapse after ASCT that might benefit from other approaches. We conducted a retrospective analysis on 126 patients treated with tandem ASCT-reduced intensity conditioning (RIC)-allogeneic-SCT and reported to the EBMT registry to analyze the efficacy and safety of this approach. Patients were included if they had received an ASCT followed by a planned RIC-SCT in <6 months without relapse between the procedures. The median time between diagnosis and ASCT was 16 months (2-174). The median number of lines prior to ASCT was two (33% of the patients received >3 lines). Forty-one percent were transplanted with active disease. The median follow-up was 44 months (6-130). Three-year-progression-free survival (PFS), overall survival (OS), incidence of relapse (IR), and non-relapse mortality (NRM) after the tandem were 53% (45-64), 73% (65-81), 34% (24-42), and 13% (8-21), respectively. This is the largest series analyzing the efficacy and safety of a tandem approach in R/R HL. The low NRM and IR with promising PFS and OS suggest that this might be an effective procedure for a high-risk population.

Abstract
Reduced-intensity conditioning (RIC) allogeneic haematopoietic cell transplantation (allo-HCT) is a curative option for select relapsed/refractory Hodgkin lymphoma (HL) patients; however, there are sparse data to support superiority of any particular conditioning regimen. We analyzed 492 adult patients undergoing human leucocyte antigen (HLA)-matched sibling or unrelated donor allo-HCT for HL between 2008 and 2016, utilizing RIC with either fludarabine/busulfan (Flu/Bu), fludarabine/melphalan (Flu/Mel140) or fludarabine/cyclophosphamide (Flu/Cy). Multivariable regression analysis was performed using a significance level of <0.01. There were no significant differences between regimens in risk for non-relapse mortality (NRM) (P = 0.54), relapse/progression (P = 0.02) or progression-free survival (PFS) (P = 0.14). Flu/Cy conditioning was associated with decreased risk of mortality in the first 11 months after allo-HCT (HR = 0.28; 95% CI = 0.10-0.73; P = 0.009), but beyond 11 months post allo-HCT it was associated with a significantly higher risk of mortality, (HR = 2.46; 95% CI = 0.1.32-4.61; P = 0.005). Four-year adjusted overall survival (OS) was similar across regimens at 62% for Flu/Bu, 59% for Flu/Mel140 and 55% for Flu/Cy (P = 0.64), respectively. These data confirm the choice of RIC for allo-HCT in HL does not influence risk of relapse, NRM or PFS. Although no OS benefit was seen between Flu/Bu and Flu/Mel 140; Flu/Cy was associated with a significantly higher risk of mortality beyond 11 months from allo-HCT (possibly due to late NRM events).

Abstract
The purpose of this study was to analyze the results of second autologous hematopoietic stem cell transplantation (ASCT2) for patients with relapsed/refractory Hodgkin lymphoma (HL) after a first transplantation (ASCT1). Outcomes for 56 patients receiving an ASCT2 registered in the EBMT database were analyzed. The 4-year cumulative incidences of non-relapse mortality and disease relapse/progression were 5% and 67%, respectively. The 4-year overall survival (OS) and progression-free survival (PFS) were 62% and 28%. In univariate analysis, relapse of HL within 12 months of ASCT1 was associated with a worse OS (35% versus 76%, p = 0.01) and PFS (19% versus 29%, p = 0.059). Chemosensitivity at ASCT2 predicted better outcomes (4-year OS 72% versus 29%, p = 0.002; PFS 31% versus 12%, p = 0.015). This series shows that ASCT2 is a safe procedure and a relatively effective option for patients with late relapses after ASCT1 and with chemosensitive disease who are not eligible for an allogeneic transplant.

Abstract
BACKGROUND In this work, we assessed the efficacy and safety of brentuximab vedotin (BV) plus ESHAP (BRESHAP) as second-line therapy for Relapsed/Refractory Hodgkin lymphoma (RRHL) to improve the results before autologous stem-cell transplantation (ASCT). PATIENTS AND METHODS This was a multicenter, open-label, phase I-II trial of patients with RRHL after first-line chemotherapy. Treatment had three 21-day cycles of etoposide, solumedrol, high-dose AraC, and cisplatin. BV was administered at three dose levels (0.9, 1.2, and 1.8 mg/kg) intravenous on day 1 to 3 + 3 cohorts of patients. Final BV dose was 1.8 mg/kg. Responding patients proceeded to ASCT, followed by three BV courses (1.8 mg/kg, every 21 days). Main end points for evaluation were maximum tolerable dose and overall and complete response (CR) before ASCT. RESULTS A total of 66 patients were recruited (median age 36 years; range 18-66): 40 were primary refractory, 16 early relapse and 10 late relapse. There were 39 severe adverse events were reported in 22 patients, most frequently fever (n = 25, 35% neutropenic), including 3 deaths. Grade 3-4 hematological toxicity presented in 28 cases: neutropenia (n = 21), thrombocytopenia (n = 14), and anemia (n = 7). Grade ≥3-4 extrahematological adverse events (≥5%) were non-neutropenic fever (n = 13) and hypomagnesaemia (n = 3). Sixty-four patients underwent stem-cell mobilization; all collected >2x10e6/kg CD34+ cells (median 5.75; range 2.12-33.4). Overall response before transplant was 91% (CI 84% to 98%), including 70% (CRs 95% CI 59% to 81%). 60 patients were transplanted with no failure engraftments. Post-transplant response was CR in 49 patients (82% CI 73% to 91%) and partial responses in six (10% CI 5% to 15%). After a mean follow-up of 27 months, the 30-month time to treatment to failure was 74% (95% CI 68% to 80%), progression-free survival 71% (95% CI 65% to 77%), and overall survival 91% (CI 84% to 98%). CONCLUSION BRESHAP looks a safe and effective pre-transplant induction regimen, does not jeopardize transplant and allows long-term remissions and survival.

Abstract
Classical Hodgkin lymphoma (cHL) patients with relapsed or refractory disease may benefit from allogeneic hematopoietic cell transplantation (allo-HCT), but many lack a matched sibling donor (MSD). Herein, we compare outcomes of two reduced-intensity conditioning (RIC) HCT platforms in cHL: T cell-replete related donor haploidentical (haplo) HCT with post-transplantation cyclophosphamide (PTCy)-based approach versus MSD/calcineurin inhibitor (CNI)-based approach. The study included 596 adult patients who underwent a first RIC allo-HCT for cHL between 2008-2016, using either haplo-PTCy (n=139) or MSD/CNI-based (n=457) approach. Overall survival (OS) was the primary endpoint. Secondary endpoints included acute (a) and (c) graft-versus-host disease (GVHD), non-relapse mortality (NRM), relapse/progression, and progression-free survival (PFS). On multivariate analysis, there was no significant difference between haplo/PTCy and MDS/CNI-based approaches in terms of OS (hazard ratio [HR]=1.07; 95%CI=0.79-1.45; p=0.66) or PFS (HR=0.86; 95%CI=0.68-1.10; p=0.22). Haplo/PTCy was associated with a significantly higher risk of grade 2-4 aGVHD (odds ratio [OR]=1.73, 95%CI=1.16-2.59, p=0.007), but the risk of grade 3-4 aGVHD was not significantly different between the two cohorts (OR=0.61, 95%CI=0.29-1.27, p=0.19). The haplo/PTCy platform provided a significant reduction in cGVHD risk (HR=0.45, 95%CI=0.32-0.64, p<0.001), and a significant reduction in relapse risk (HR=0.74, 95%CI=0.56-0.97, p=0.03). There was a statistically non-significant trend towards higher NRM with haplo/PTCy approach (HR=1.65, 95%CI=0.99-2.77, p=0.06). Haplo/PTCy-based approaches are associated with lower incidence of cGVHD and relapse, with PFS and OS outcomes comparable to MSD/CNI-based approaches. There was a leaning towards higher NRM with haplo/PTCy-based platform. These data show that haplo/PTCy allo-HCT in cHL results in survival comparable to MSD/CNI-based allo-HCT.
PICO Summary
Population
Adult patients who underwent a first RIC allo-HCT for classical Hodgkin lymphoma between 2008-2016 (n=596)

Outcome
On multivariate analysis, there was no significant difference between Haplo/PTCy and MSD/CNI-based approaches in terms of overall survival or progression-free survival. Haplo/PTCy was associated with a significantly higher risk of grade 2-4 aGVHD, but the risk of grade 3-4 aGVHD was not significantly different between the two cohorts. The haplo/PTCy platform provided a significant reduction in cGVHD risk, and a significant reduction in relapse. There was a statistically non-significant trend towards higher NRM with haplo/PTCy approach.

Abstract
The phase 3 AETHERA trial demonstrated brentuximab vedotin's (BV) efficacy as consolidation therapy in patients with classical Hodgkin lymphoma (HL) at high risk of relapse or progression following autologous hematopoietic stem cell transplant (auto-HSCT; hazard ratio [HR]=0.57; P<0.001). The objective of this analysis is to provide further detail on the most common and clinically important treatment-emergent adverse events (TEAEs) in the AETHERA BV arm including their occurrence and management. AEs of clinical importance occurring in patients who participated in AETHERA (BV + best supportive care [BSC], n=165; placebo + BSC, n=164) were evaluated for time to onset, manageability through dose modification, and resolution. As previously reported, peripheral neuropathy (PN; 67%), infections (60%), and neutropenia (35%) were the most common BV-associated TEAEs. Neutropenia was managed with dose delays and granulocyte colony-stimulating factor; no dose reductions or discontinuations were required. The majority (57%) of PN cases were managed with dose delays and reductions. The median time to PN onset was 13.7 (range, 0.1-47.4) weeks. After end of treatment, PN continued to resolve; symptom resolution was similar to that in the placebo arm at 3 years, demonstrating reversibility. BV had no significant impact on preexisting PN. Patients with PN-related dose modifications had progression-free survival (PFS) comparable to patients without. Other less common but serious AEs, including pulmonary toxicities, hepatotoxicity, and cardiotoxicity, were rare in both arms and managed with BV dose modifications or discontinuations. Secondary malignancies were rare and reported in patients with comorbidities or other risk factors. Consolidation therapy with BV for patients with HL at high risk of relapse after auto-HSCT is associated with sustained PFS. The most common AEs in the BV arm were manageable and reversible. Awareness of these AEs and management approaches will enable healthcare providers and patients to plan the safest and most effective treatment plan.
