Abstract Background: Patients with classical Hodgkin lymphoma (cHL) who progress after brentuximab vedotin (BV) have a poor prognosis. cHL frequently harbors genetic alterations at the 9p24.1 locus, resulting in the overexpression of the PD-L1 and PD-L2 immune checkpoint ligands. Pembrolizumab is a humanized monoclonal antibody that blocks the interaction between the PD-1 receptor and PD-L1/PD-L2, and can restore antitumor immune activity in several different tumors. Based on its likely genetically driven dependence on PD-1, cHL was included as an independent expansion cohort in the KEYNOTE-013 study (NCT01953692), a multicenter, multicohort phase 1b trial of pembrolizumab in patients with hematologic malignancies. Updated results from this cohort, including long-term efficacy, are presented. Methods: Key eligibility criteria for the cHL cohort of KEYNOTE-013 included relapse after or ineligibility for autologous stem cell transplantation (ASCT), and relapse after or refractory to BV treatment. Pembrolizumab was administered intravenously at a dose of 10 mg/kg every 2 weeks for up to 2 years or until confirmed progression or unacceptable toxicity. Response was assessed at week 12 and every 8 weeks thereafter according to the International Harmonization Project 2007 criteria. The primary end points were safety and complete remission (CR) rate (CRR); secondary end points included overall response rate (ORR) and duration of response (DOR). Patients who achieved a CR could opt to stop treatment after 24 weeks provided that they received at least 2 doses after CR. This report includes CRR, ORR, and DOR by blinded independent central review (BICR). Results: At the time of data cutoff on June 3, 2016, 31 patients were enrolled, and all were evaluable for analysis. Median follow-up duration was 24.9 months (range, 7.0-29.7 months). The median number of prior lines of therapy was 5 (range, 2-15), 74% of patients had failed prior ASCT, and by design 100% had failed prior BV. Per investigator review, ORR was 65%, and CRR was 19%. Per BICR, ORR was 58% (18/31), with 6 patients (19%) achieving CR and 12 (39%) partial remission; 7 patients (23%) had stable disease as their best response. Median DOR was not reached, with a range of 0.0+ to 21.4+ months (95% CI, 3.7 months to not reached) (Figure). An analysis with hierarchical mutually exclusive categories of refractory disease (RD; defined as no response to ≥1 prior line of therapy) or relapse after ≥3 prior lines of therapy (Re ≥3) was conducted. Per BICR, the ORR was 56% in RD (n = 27 patients) and 75% in Re ≥3 (n = 4). As of the data cutoff date, 3 patients (10%) remained on treatment, 5 (16%) completed 2 years of treatment, and 23 (74%) discontinued treatment: 3 (10%) for toxicity, 14 (45%) for progressive disease, 3 (10%) per physician decision (all ultimately underwent allogeneic SCT), 1 in CR (underwent allogeneic SCT), 1 for clinical progression, and 1 who withdrew consent. Per BICR, median progression-free survival (PFS) was 11.4 months; 6-month and 12-month PFS rates were 66% and 48%, respectively. Median overall survival (OS) was not reached; 6-month and 12-month OS rates were 100% and 87%, respectively. Conclusions: With nearly 2.5 years of median follow-up, the present results demonstrate that a subset of heavily pretreated patients who failed BV therapy can achieve a long-term response with single-agent pembrolizumab, without consolidative therapy. PD-1 blockade may offer a new treatment paradigm for patients with relapsed/refractory cHL, supporting the hypothesis that this tumor has a genetic dependence on the PD-1 pathway. Figure Figure.

Abstract Background: Classical Hodgkin lymphoma (cHL) displays near-universal genetic deregulation of PD-1 ligand expression, and relapsed/refractory (R/R) cHL is uniquely sensitive to PD-1 blockade. However, such treatment for patients (pts) who relapse after or are ineligible for autologous stem cell transplantation (ASCT) appears to be rarely, if ever, curative. Deploying PD-1 blockade early after ASCT could leverage the remodeling immune landscape and minimal residual disease state to increase the cure rate of ASCT. We therefore conducted a phase 2 multi-center single-arm study of the anti-PD-1 monoclonal antibody pembrolizumab (pembro) in pts with chemosensitive R/R cHL after ASCT. Another arm of this study enrolled pts with R/R DLBCL and will be presented separately. Methods: Adult pts with R/R cHL who had received 2-3 lines of prior therapy and ASCT and who were chemosensitive prior to ASCT were enrolled on this study. In addition to meeting standard eligibility criteria for pembro treatment, pts had to have recovered from ASCT toxicities and begin study treatment within 60 days of stem cell infusion (goal within 21 days). They received pembro 200mg IV every 3 weeks for 8 cycles. PET-CT scans were obtained at post-ASCT baseline, after 3 and 7 cycles, then at 12 and 18 months post-ASCT. The primary endpoint was the progression-free survival rate (PFS) at 18 months after ASCT, assessed using International Harmonization Project 2007 criteria. Results: 31 pts were enrolled and 1 withdrew consent before starting treatment. Among the 30 eligible patients, median age was 33 (20-69). 26 pts (87%) were high-risk by virtue of primary refractory disease (57%), relapse within 12 months (17%), extranodal disease at relapse (27%) or absence of metabolic CR at ASCT (10%). At study baseline post-ASCT, 97% were in CR. 24 pts (80%) completed 8 cycles of pembro per protocol. 6 pts (20%) stopped pembro early for pt choice (n=2, including 1 pt with gr2 pneumonitis) or toxicity (n=4, including 2 pts with gr3 hepatitis, 1 with g3 pneumonitis, 1 with g2 diplopia). 9 pts (30%) experienced a total of 28 gr3 or higher adverse events (AEs). The most common gr4 AE was neutropenia (10%). 3 patients (10%) experienced 7 gr3-4 AEs at least probably related to pembro (gr3 diarrhea and gr3 eosinophilic colitis in 1 pt, gr3 leukopenia and gr4 neutropenia in 1 pt, gr3 leukopenia and gr3 ALT and AST elevation in 1 pt). 11 pts (37%) experienced at least one immune-related AE of gr2 or higher severity: pneumonitis (n=2 gr2, n=1 gr3), thyroid dysfunction (n=1 gr2), transaminitis (n=2 gr3), colitis/diarrhea (n=1 gr2, n=2 gr3), rash (n=2 gr2), pulmonary hemorrhage (n=1 gr3), arthritis (n=1 gr2), and increased creatinine (n=1 gr2). There was no treatment-related death. Among the 30 eligible pts, 2 were lost to follow-up after their 12m assessments (both in CR). 27 pts (90%) were evaluable for the primary endpoint (the last pt is still in follow-up and results will be updated for the meeting). 6 patients (20%) relapsed at a median of 8 months (3-18) from ASCT, and all other evaluable patients were in CR at the 18m timepoint. The KM estimate of 18m PFS for high-risk patients was 78% (95%CI 54-91). The 18m overall survival was 100%. Tumor biopsies from a pt who progressed on study demonstrated an increase in the %age of PD1+ T cells at progression, as well as an increase in the %age of PD-L1+ macrophages and PD-L1+ Reed-Sternberg cells (Figure). Other correlative studies including immune reconstitution and MRD analyses are ongoing. Conclusions: Pembrolizumab administered after ASCT in patients with R/R cHL has a safety profile that appears similar to its use in the R/R setting, although possibly with a higher rate of neutropenia. The 18-month progression-free rate in this high-risk cohort compares favorably with previous published studies, and supports the hypothesis that PD-1 blockade in this setting may increase the efficacy of ASCT. This should be tested in a randomized trial. Figure. Figure.

Abstract The programmed death-1 (PD-1) pathway serves as an immune checkpoint to temporarily dampen immune responses upon chronic antigen stimulation. Normal antigen presenting cells and certain tumor cells express the PD-1 ligands, PD-L1 and PD-L2, which engage PD-1 receptors on activated T cells and induce T-cell exhaustion. PD-1 signaling is a potent mechanism of tumor immune escape and a compelling target for therapy. Antibody-mediated PD-1 blockade has already been successfully exploited as a therapeutic strategy in solid tumors and is currently being evaluated in hematologic malignancies. Classical Hodgkin lymphoma (cHL) may represent a uniquely vulnerable target for PD-1 blockade therapy. This disease is characterized by an extensive inflammatory immune cell infiltrate and a dominant genetic alteration in chromosome 9p24.1 that leads to PDL1 and PDL2 copy gain and associated overexpression of these PD-1 ligands. In cHL, Epstein-Barr virus infection represents an additional mechanism of upregulating PD-1 ligand expression. For these reasons, cHL was included as a cohort of the ongoing, multicenter, open-label, phase 1b clinical trial of the monoclonal antibody pembrolizumab (MK-3475; Merck, Whitehouse Station, NJ) in hematologic malignancies (KEYNOTE-013; ClinicalTrials.gov identifier, NCT01953692). Eligibility criteria for the cHL arm of KEYNOTE-013 include relapsed or refractory cHL, relapse from or failure to respond to brentuximab vedotin treatment, and adequate performance status and organ function. Patients with autoimmune disease or interstitial lung disease are excluded. Treatment consists of single-agent pembrolizumab 10 mg/kg administered intravenously every 2 weeks until confirmed tumor progression, excessive toxicity, or completion of 2 years of therapy. The main end points of this study are safety, tolerability, and complete remission (CR) rate. The first time point for radiologic restaging is at week 12 (ie, after 6 cycles of treatment). Herein, we report preliminary results from the 15 patients with cHL who were evaluable for response to pembrolizumab at the 12-week time point. The median patient age was 28 years (range, 21-67), and the median number of prior therapies was 4. By design, all patients previously failed brentuximab vedotin; 67% also failed prior autologous stem cell transplantation. Pembrolizumab was well tolerated. There were no serious adverse events (AEs), and only 1 patient experienced grade 3-5 AEs (grade 3 pain and grade 3 joint swelling, both considered to be unrelated to study drug). Overall, 10 patients experienced ≥1 AE. The most common drug-related AEs were grade 1-2 respiratory events (20%) and thyroid disorders (20%). One patient discontinued study treatment because of an AE (grade 2 pneumonitis), and 3 patients ended therapy after progressive disease (PD). Based on investigator assessment using the Cheson 2007 International Harmonization Project response criteria, 3 patients (20%) had a CR at 12 weeks. Five additional patients (33%) had partial remission as best overall response, for an overall response rate of 53%. Four patients (27%) experienced PD, although all 4 experienced a decrease in their overall tumor burden (Figure 1). In conclusion, pembrolizumab therapy appears to be safe, tolerable, and associated with clinical benefit in patients with heavily pretreated cHL.

Introduction: About 2 to 10% of patients (pts) diagnosed with Chronic Lymphocytic Leukemia (CLL) develop diffuse large B-cell lymphoma (DLBCL, so-called Richter transformation (RT)) over long-term follow-up. The outcomes of pts with RT are variable and poorly understood and there is no consensus on the best therapeutic approach. The aim of this study was to analyze the clinical characteristics, outcomes and factors predictive of survival in a large series of RT from the French Innovative Leukemia Organization (FILO). Methods: Biopsy-confirmed RT (limited to DLBCL and excluding Hodgkin lymphoma) diagnosed from 2001 to 2018 were identified from eight FILO centers. Clinical and biological characteristics of CLL and RT at diagnosis, including cytogenetics, clonal relation with the pre-existing CLL, Epstein-Barr virus (EBV) status, cell of origin (COO) analyzed by immunohistochemistry and RT score (Tsimberidou AM et al, J Clin Oncol, 2006) were analyzed as well as treatment and outcomes. Overall survivals (OS) were defined as time from CLL and RT diagnosis to death from any cause and analyzed using the Kaplan-Meier method. Statistical analyses were performed with SAS version 9.4. Results: A total of 70 CLL pts who developed RT were identified. The median age at CLL diagnosis was 62 years old (range 35-82), and 50 (71.4 %) were male. The median time to transformation was 5.5 years (range 0 to 22 years), with 12 simultaneous diagnosis of CLL and RT. Prior to RT, 20 (29%) pts had not been treated for CLL, 50 received one (n=21) or more (n= 29) line of treatment ; 6 pts had received a novel agent (ibrutinib, idelalisib or venetoclax). The median age at RT diagnosis was 68 years old (range 42-88). All biopsies were centrally reviewed; 38/58 pts (66%) had elevated LDH (>1.5N) ; 35/65 pts (54 %) had bulky disease (≥ 5 cm); 10/54 (18.5%) pts had del(17p) or TP53 mutation ; 9/42 pts (21%) had a complex karyotype (at least 3 abnormalities). The CLL and RT were clonally related in 27/27 (100%) tested pts. COO by Hans algorithm was non germinal center B cell-like (GCB) in 26/28 pts (93%). EBV was positive or detected in 5/40 (12.5%) pts. The median of Ki67 positivity was 70% (range 30% to 100%). The RT score (based at RT diagnosis on ECOG performance status 2-4, LDH >1.5 x normal, platelets<100 x 109/L, tumor size >5 cm and >1 prior therapy for CLL) was : low risk in 17 pts (31%), low-intermediate risk in 10 pts (19%), high-intermediate risk in 14 pts (25%) and high risk in 14 pts (25%). The most common first-line treatment of RT was immunochemotherapy (n=57, 87%) including R-CHOP-like regimen (n=48, 73%). Autologous or allogeneic transplantation was performed for 7 pts (11%). Response to first-line treatment was complete or partial response in 26 pts (40%), and stable disease or progression in 39 pts (60%). After a median follow-up of 8 years, 51/64 pts (80%) have died. The main causes of death were progressive DLBCL (n=36, 71%), infection (n=8, 16%) or progressive CLL (n=2, 4%). The median OS of the cohort from CLL and RT diagnosis (Figure 1) were 7.8 years and 9.5 months, respectively. In univariate analysis, patients with TP53 disruption at CLL stage, low platelets count, elevated LDH, elevated beta2-microglobulin, high ECOG score, high RT score, EBV positivity and absence of response to first-line RT treatment had worse OS. The ECOG score, platelets count and TP53 disruption remain significant in multivariate Cox-regression. Last, we compared the clinical and biological parameters of two Richter groups defined as: (i) short-term survivors (<12 months, n = 34) and (ii) long-term survivors (>48 months, n = 18). Long survival was significantly associated with elevated platelets count, low LDH, low ECOG, low RT score and response to RT first-line treatment. Discussion: The clinical outcomes of RT patients is poor and novel treatment options are needed. However, a group of long-term survivors was identified, characterized by elevated platelets count, low LDH, low ECOG, low RT score and response to immunochemotherapy.

Introduction: The R-MegaCHOEP trial showed that dose-escalation of conventional chemotherapy necessitating autologous stem cell transplantation (ASCT) does not confer a survival benefit for younger patients (pts) with high-risk aggressive B-cell lymphoma in the Rituximab era (Schmitz et al., Lancet Oncology 2012; 13, 1250-1259). To describe efficacy and toxicity over time and document the long-term risks of relapse and secondary malignancy we present the 10-year follow-up of this study. Methods: In the randomized, prospective phase 3 trial R-MegaCHOEP younger pts aged 18-60 years with newly diagnosed, high-risk (aaIPI 2-3) aggressive B-cell lymphoma were assigned to 8 cycles of CHOEP (cyclophosphamide, doxorubcine, vincristine, etoposide, prednisone) or 4 cycles of dose-escalated high-dose therapy (HDT) necessitating repetitive ASCT both combined with Rituximab. Both arms were stratified according to aaIPI, bulky disease, and center. Primary endpoint was event-free survival (EFS). All analyses were calculated for the intention-to-treat population. This follow-up report includes molecular data based on immunohistochemistry (IHC) and fluorescent in situ hybridization (FISH) for MYC (IHC: 31/92 positive [40-100%], FISH: 14/103 positive), BCL2 (IHC: 65/89 positive [50-100%], FISH: 23/111 positive) and BCL6 (IHC: 52/86 positive [30-100%], FISH: 34/110 positive) and data on cell of origin (COO) classification according to the Lymph2CX assay (GCB: 53/88; ABC: 24/88; unclassified: 11/88). Results: 130 pts had been assigned to R-CHOEP and 132 to R-MegaCHOEP. DLBCL was the most common lymphoma subtype (~80%). 73% of pts scored an aaIPI of 2 and 27% an aaIPI of 3. 60% of pts had an initial lymphoma bulk and in 40% more than 1 extranodal site was involved. After a median observation time of 111 months, EFS at 10 years was 57% (95% CI 47-67%) in the R-CHOEP vs. 51% in the R-MegaCHOEP arm (42-61%) (hazard ratio 1.3, 95% CI 0.9-1.8, p=0.228), overall survival (OS) after 10 years was 72% (63-81%) vs. 66% (57-76%) respectively (p=0.249). With regard to molecular characterization, we were unable to detect a significant benefit for HDT/ASCT in any subgroup analyzed. In total, 16% of pts (30 pts) relapsed after having achieved a complete remission (CR). 23% of all relapses (7 pts) showed an indolent histology (follicular lymphoma grade 1-3a) and 6 of these pts survived long-term. In contrast, of 23 pts (77%) relapsing with aggressive DLBCL or unknown histology 18 pts died due to lymphoma or related therapy. The majority of relapses occurred during the first 3 years after randomization (median time: 22 months) while after 5 years we detected relapses only in 5 pts (3% of all 190 pts prior CR). 11% of pts were initially progressive (28 pts) among whom 71% (20 pts) died rapidly due to lymphoma. Interestingly, the remaining 29% (8 pts) showed a long-term survival after salvage therapy (+/- ASCT); only 1 pt received allogeneic transplantation. The frequency of secondary malignancies was very similar in both treatment arms (9% vs. 8%) despite the very high dose of etoposide (total 4g/m2)in the R-MegaCHOEP arm. We observed 2 cases of AML and 1 case of MDS per arm. In total 70 pts (28%) have died: 30 pts due to lymphoma (12%), 22 pts therapy-related (11 pts due to salvage therapy) (9%), 8 pts of secondary neoplasia (3%), 5 pts due to concomitant disease (2%) and 5 pts for unknown reasons. Conclusions: This 10-year long-term follow-up of the R-MegaCHOEP trial confirms the very encouraging outcome of young high-risk pts following conventional chemotherapy with R-CHOEP. High-dose therapy did not improve outcome in any subgroup analysis including molecular high-risk groups. Relapse rate was generally low. Pts with aggressive relapse showed a very poor long-term outcome while pts with indolent histology at relapse survived long-term. Secondary malignancies occurred; however, they were rare with no excess leukemias/MDS following treatment with very high doses of etoposide and other cytotoxic agents.

Purpose: Hodgkin's lymphoma (HL) is a highly curable disease even in advanced-stage, with &gt;90% of long-term survivors. Currently, the standard of care is ABVD (doxorubicin, etoposide, vinblastine and dacarbazine), as it is less toxic and as effective as other more intensive chemotherapy regimens. Alternatively, BEACOPP (bleomycin, etoposide, doxorubicin, cyclophosphamide, vincristine, procarbazine and prednisone) has been proposed as front-line intensified regimen with a better initial disease control and prolonged time to relapse when compared to ABVD. However, this advantage is associated with higher rates of severe hematologic toxicity, treatment-related deaths, secondary neoplasms and infertility. To date, the debate regarding which regimen should be preferred as first line for advanced-stage HL is still ongoing. To shed some light on this open question we compared efficacy and safety of both regimens in clinical practice. Patients and Methods: From October 2009 to October 2018, patients with HL stage III-IV treated with either ABVD or BEACOPP escalated (BEACOPPesc) were retrospectively assessed in 7 European cancer centers. Results: A total of 372 consecutive patients were included in the study. One-hundred and ten patients were treated with BEACOPPesc and 262 with ABVD. The baseline characteristics of the two groups did not differ significantly, except for a higher rate of high-risk patients in the BEACOPPesc group in contrast to the ABVD one (47% vs 18%; p= 0.003). Complete response rate (CR) assessed by PET imaging at the end of the second cycle was 67% and 78% for the ABVD and BEACOPPesc group (p= 0.003), respectively. Thirteen patients of the ABVD group achieved stable disease (SD) and 6 had a progression disease (PD). On the other hand, 4 of the patients in the BEACOPPesc group progressed, another 2 interrupted therapy because life-threatening toxicity. At the end of the therapy, CR was 76% in the ABVD group and 85% in the BEACOPPesc group (p= 0.01). A total of 20% patients in the ABVD group and 14% patients in the BEACOPPesc group received consolidation radiotherapy on the mediastinal mass at the dose of 30Gy. After radiotherapy, the number of patients with CR increased to 79% and 87% in the two groups (p= 0.041), respectively. Thirty-nine patients (35%) in the BEACOPPesc group required dose reduction of chemotherapy due to toxicity compared to 12 patients (5%; p= &lt;0.001) in the ABVD group. Overall, the rate of severe toxicities was higher in the BEACOPPesc group in comparison with the ABVD cohort. In particular, there was a significant increased frequency of acute grade 3-4 hematologic adverse events (neutropenia 61% vs 24%; anemia 29% vs 4%; thrombocytopenia 29% vs 3%), febrile neutropenia (29% vs 3%), severe infections (18% vs 3%). Myeloid growth factors were administered to 85% and 59% of patients in the BEACOPPesc group compared to the ABVD group. Blood transfusions were required in 51% and 6% of patients in the BEACOPPesc group compared to the ABVD cohort. Progression during or shortly after treatment occurred in 5 patients in the BEACOPPesc group (4%) and in 16 patients in the ABVD group (6%; p= 0.62). Among the 96 patients who achieved a CR after BEACOPPesc and radiotherapy, 8 relapsed (8%), compared to 29 of 208 patients in the ABVD group (14%; p= 0.04). At a median follow-up period of 5 years, no statistical difference in progression free survival (PFS; p=0.11) and event-free survival (EFS; p=0.22) was observed between the BEACOPPesc and ABVD cohorts. Similarly, overall survival (OS) did not differ between the two groups (p=0.14). The baseline international prognostic score (IPS &lt;3 vs ≥ 3) significantly influenced the EFS with an advantage for the high-risk group treated with BEACOPPesc (Figure 1A; p=0.03), but not the PFS (Figure 1B; p=0.06) and OS (Figure 1C; p=0.14). During the follow-up period, in the BEACOPPesc group one patient developed myelodysplasia and one acute leukemia. Second solid tumors developed in one patient in the ABVD group (lung cancer) and one in BEACOPPesc group (breast cancer). Conclusion: We confirm that the ABVD regimen is an effective and less toxic therapeutic option for advanced-stage HL. Although BEACOPP results in better initial tumor control especially in high-risk patients, the long-term outcome remains similar between the two regimens.

Abstract Abstract 2677 Background: Classical Hodgkin lymphoma (CHL), which is characterized by the presence of Hodgkin and Reed Sternberg (H-RS) cells in a background of non-neoplastic inflammatory cells, is divided into four histological subgroups, nodular sclerosis (NSCHL), mixed cellularity (MCCHL), lymphocyte-rich, and lymphocyte depletion. While NSCHL in young adults is characterized by a mediastinal mass and good prognosis, the clinicopathological characteristics of NSCHL in the elderly (NSCHL-e) remain uncertain. Patients and methods: Enrolled patients were diagnosed with CHL between 1986 and 2006 as part of the Hodgkin Lymphoma's Multicenter Study Group. To better characterize NSCHL-e, we compared the clinicopathological profiles of 84 NSCHL-e patients aged 50 or over with 237 NSCHL-y patients aged 49 or younger and 302 with MCCHL. Results: The total of 743 CHL patients consisted of 496 men and 247 women with a median age of 48 years (range, 15– 89 years). The pathological diagnoses were NSCHL in 324 patients (43%) and MCCHL in 303 (41%). NSCHL patients showed a bimodal age distribution, with an initial peak in their 20s and a second small peak in their 60s. We categorized the former as NSCHL-y (49 or younger) and the latter as NSCHL-e (50 and over). NSCHL-e patients were characterized by male predominance and a more advanced clinical stage (53%) than NSCHL-y. Immunophenotypically, H-RS cells had the prototypic immunophenotype of CD15+ CD30+ and Pax5+. NSCHL-e cases showed a significantly higher rate of CD20 (24%) than NSCHL-y (8%, P = 0.001). Furthermore, H-RS cells in 29 of 75 (39%) patients with NSCHL-e were positive for EBV RNA transcripts by in situ hybridization, whereas only 7% of NSCHL-y cases were EBER-positive (P < 0.0001) (Table). Regarding NSCHL-e and MCCHL, no significant difference between these patients was seen in clinical characteristics. Immunophenotypically, NSCHL-e patients showed significantly higher rates for CD3 and TIA-1, while MCCHL patients showed higher EBV positivity (75%). Fifty-five of 63 patients received systemic multi-agent chemotherapy as first-line treatment, consisting of doxorubicin, bleomycin, vinblastine, and dacarbacin (ABVD) in 38 patients; CHOP in 8; C-MOPP in 8; and BEACOPP in 1. Overall, 51 patients responded to first-line treatment, 39 with complete response and 12 with partial response. Disease-specific survival of NSCHL-e was poorer than that of NSCHL-y (P < 0.001) but similar to that of MCCHL (P = 0.43) (Figure). Conclusion: NSCHL-e is characterized by an unfavorable prognosis and different clinicopathological features to NSCHL-y, which is considered as typical NSCHL. A number of cases of NSCHL-e might have been associated with MCCHL, with most being EBV-positive. These results suggest the limitations of current histological subgroupings for CHL.

Abstract Abstract 3697 Introduction: Rituximab has been a useful treatment for patients with ITP; many hundreds of patients have been treated. 30–40% of patients will achieve a complete remission (CR: platelet count >150 × 109/l) with initial treatment and, of this group, the CR will last at least a year in almost all patients. However, emerging data suggests that at least 40% of these patients in CR will relapse between 1 and 3 years from initial treatment suggesting that long-term “cures” only occur in 20% of the initial patients. Therefore it would be desirable if CR's could be achieved in more patients and especially if these would be durable in more than 20%. One approach would be to use rituximab maintenance, however it results in suppression of B-cells for more than 2 years. Dexamethasone has also been used to achieve “cure” in ITP especially in adults at or near diagnosis. Cheng's study suggested that approximately 50% of patients would achieve a long-term response with only one 4-day cycle of high dose (40 mg/day) dexamethasone (N Engl J Med, 2003). A follow up study from GIMEMA suggested that 3–4 cycles of dexamethasone would be better than 1 cycle (Blood, 2007). Finally, Zaja's study suggested that rituximab plus one cycle of dexamethasone was superior to dexamethasone alone with a > 50% CR rate at 6 months (Blood, 2010). Therefore, we elected to perform a pilot study to explore the combination of rituximab with three cycles of dexamethasone at 14 day intervals. Methods: Patients with ITP with platelet counts < 30,000 off therapy and in need of treatment were enrolled. The standard dose (4 infusions of 375mg/m2) rituximab was given on days 1, 8, 15 and 22 and dexamethasone 40 mg (adjusted for size) on days 1–4, 15–18, and 29–32. Results: Fourteen patients between the ages of 4 and 53 years with ITP were treated with rituximab and dexamethasone (R&D) (Table 1). All had received previous steroid therapy as well as other treatments. The median platelet count was 40,000 at initiation of rituximab (range 7,000-230,000); several patients with low counts started with dexamethasone prior to initiating Rituximab to sustain their counts during initial treatment. Patients received rituximab weekly for between 2 and 4 doses and dexamethasone for either 2 or 3 courses at intervals between 1 and 8 weeks (median 2 week intervals). A summary of the results is shown in table 2 demonstrating short-lived platelet increases in response to dexamethasone in almost all patients. With short follow up, there were 7 CR's, 3 PR's and 4 NR's. If this was divided by duration of ITP prior to R&D, there were 4 CR's and 1 NR for ≤ 12 months and 3 CR, 3 PR, and 3 NR for > 12 months. More of the children who were treated had chronic disease than did adults explaining their apparently poorer response. Observed toxicities included hyperglycemia, grade 1 and 2 liver function abnormalities, weight gain, and 1 episode of colitis requiring hospitalization. Three patients opted to skip the third cycle of dexamethasone. Conclusion: A regimen of rituximab + 2–3 courses of dexamethasone is active in patients with pretreated ITP with appreciable but usually manageable toxicity. It appears to yield superior results if administered to patients within one year of diagnosis. This combination merits further exploration in a prospective clinical trial.

Abstract Abstract 3077 Blastic plasmacytoid dendritic cell neoplasm (BPDC), formerly known as blastic NK cell lymphoma, is a rare hematopoietic malignancy preferentially involving the skin, bone marrow and lymph nodes. The overall prognosis of BPDC is dismal. Most patients show an initial response to acute leukemia-like chemotherapy, but relapses with subsequent drug resistance occur in virtually all patients resulting in a median overall survival of only 9–13 months. However, anecdotal long-term remissions have been reported in young patients who received early myeloablative allogeneic stem cell transplantation (alloSCT). We therefore performed a retrospective analysis of patients identified in the EBMT registry in order to evaluate the outcome of autologous stem cell transplantation (autoSCT) or alloSCT for BPDC. Eligible were all patients who had been registered with a diagnosis of BPDC or Blastic NK cell lymphoma and had received autologous stem cell transplantation (autoSCT) or alloSCT in 2000–2009. Centres were contacted to provide a written histopathology and immunophenotyping report and information about treatment and follow-up details. Patients who did not have a diagnostic score ≥ 2 as proposed by Garnache-Ottou et al. (BJH 2009) were excluded. RESULTS: Overall, 139 patients could be identified in the database who fulfilled the inclusion criteria (alloSCT 100, autoSCT 39). Of 74 patients for whom the requested additional information could be obtained, central review confirmed the diagnosis of BPDC in 39 patients (34 alloSCT, 5 autoSCT). The 34 patients who had undergone alloSCT had a median age of 41 years (range: 10–70 years), were transplanted from a related (n=11) or unrelated donor (n=23); received peripheral blood stem cells (n=9), bone marrow stem cells (n=19) or cord blood (n=6); and had been treated with a reduced intensity conditioning regimen (RIC, n=9) or myeloablative conditioning (MAC, n=25). Nineteen of 34 patients were transplanted in CR1. After a median follow up time of 28 months (range: 4–77+ months), 11 patients relapsed (median time to relapse: 8 months, range: 2–27 months) of whom 8 died due to disease progression. 9 patients died in the absence of relapse. No relapse occurred later than 27 months after transplant. Median disease free survival (DFS) was 15 months (range: 4–77+ months) and median overall survival (OS) was 22 months (range: 8–77+ months; Figure 1a). However, long-term remissions of up to 77 months after alloSCT could be observed. Patients allografted in CR1 tended to have a superior DFS (p=0.119) and OS (p=0.057; Figure 1b). MAC was associated with a better OS (p=0.001) which was attributable to the significantly higher non-relapse mortality (NRM) rate of patients after RIC (p=0.014), who had been significantly older (age RIC: 56 years, age MAC: 36 years, p=0.0014). The relapse rate was not different in patients after RIC and MAC, respectively. However, there was no survivor after RIC. Median age in the autoSCT group was 47 years (range: 14–62 years). Three of 5 patients were transplanted in CR1 of whom 1 patient relapsed after 8 months, 1 patient experienced treatment related mortality and 1 patient remained in CR for 28 months. The 2 remaining patients had more advanced disease at autoSCT and relapsed 4 and 8 months thereafter. CONCLUSION: AlloSCT is effective in BPDC and might provide curative potential in this otherwise incurable disease, especially when performed in CR1. However, it remains to be shown by prospective studies if the potential benefit of alloSCT in BPDC is largely due to conditioning intensity, or if there is a relevant contribution of graft-versus-leukemia activity.

Background: The ABVD regimen containing doxorubicin, bleomycin, vinblastine, and dacarbazine is a common standard of care for the frontline treatment of advanced stage Hodgkin lymphoma (Santoro 1987; Duggan 2003) and is curative for the majority of patients; however, up to 30% of patients require a secondary therapy. Hodgkin Reed-Sternberg cells of classical HL (cHL) typically express CD30. In a pivotal phase 2 trial brentuximab vedotin (A, ADCETRIS®), comprised of an anti-CD30 monoclonal antibody conjugated by a protease-cleavable linker to a microtubule-disrupting agent, monomethyl auristatin E (MMAE) induced an objective response rate (ORR) of 75% and complete response rate (CR) of 34% in highly treatment-refractory patients with cHL (Younes 2012). Methods: We conducted a phase 1, open-label, multicenter study to evaluate the safety and efficacy of A when administered in combination with standard therapy (ABVD) or the same regimen without bleomycin (AVD) (Younes 2013). Adult patients with newly diagnosed advanced stage (II bulky, II B, III or IV; 80% stage III or IV) received doses of 0.6, 0.9, or 1.2 mg/kg A with standard doses of ABVD or 1.2 mg/kg with AVD, depending on cohort assignment on Days 1 and 15 of each 28-day cycle for up to 6 cycles of therapy. Previously we reported that among patients assessable for response 95% of patients given ABVD+A achieved a CR, as did 96% of patients given AVD+A. None of 26 patients given AVD+A but 11 of 25 (44%) given ABVD+A experienced pulmonary toxicity, including 2 deaths, establishing that A cannot be safely combined with bleomycin. In this current study we provide the long term survival and safety data on patients enrolled in the phase 1 trial. Results: In total 51 patients were assigned to either ABVD+A (n=25) or AVD+A (n=26). 1 patient who withdrew from the trial during the first cycle of ABVD+A is excluded from this analysis and 1 patient who received 3 cycles of ABVD+A, then withdrew, then received 3 cycles of ABVD alone and 2 patients who died during treatment (pulmonary toxicity) are included (total n=50). Median follow-up from diagnosis for the 24 patients treated with ABVD+A is 41 months (range 9-51 months) and for the 26 patients treated with AVD+A, 31 months (range 9-35 months). All 26 patients treated with AVD+A have been followed longer than the longest time to relapse (7 months). 45 patients remain in first CR and 5 treatment failures have occurred: 4 in the ABVD+A cohort (2 toxic deaths; 2 relapses (9 and 23 months from diagnosis)) and 1 after AVD+A (7 months from diagnosis). 3y-failure-free survival (3y-FFS) is 83% and 96% for ABVD+A and AVD+A, respectively, and 3y-overall survival (3y-OS), is 92% and 100%. No additional toxic deaths have occurred in follow-up. Conclusions: These updated outcomes reflecting the impact of adding brentuximab vedotin (1.2 mg/kg) to standard doses of AVD for classical Hodgkin lymphoma, demonstrating 96% 3y-FFS and 100% 3y-OS with no major unexpected toxicity, strongly support the current large international trial comparing AVD-A (AVD+1.2mg/kg brentuximab vedotin) to standard ABVD (ECHELON-1, clinicaltrials.gov NCT01712490), which may identify a new, less toxic gold standard treatment for advanced stage classical Hodgkin lymphoma.

Abstract Brentuximab vedotin (BV) is an antibody drug-conjugate targeting CD30 linked to monomethyl auristatin E. Several studies have shown the efficacy of BV in patients with refractory or relapsed Hodgkin lymphoma (HL) and systemic anaplastic large cell lymphoma (sALCL). We reviewed our clinical database to evaluate the long-term efficacy of this treatment. From July 2009 to February 2015, 57 patients were treated with BV in our Institute: 43 with a diagnosis of HL and 14 with sALCL. Thirty-six were males and 21 were females, with a median age of 33 years (range 16-77). All of them had been heavily pretreated before BV with a median number of previous therapies of 3 (range 2-10). Thirty-nine had refractory disease and 18 were relapsed. Autologous stem cells transplantation had failed in 30 patients. BV was administered at a dosage of 1.8 mg/mq, every 21 days, for a maximum of 16 cycles. The median number of cycles was 8 (range 2-16); 13 patients completed the entire schedule. The best overall response rate was globally 57,8% (33 of 57 patients), including 25 (43.8%) complete responses (CR): 18 with HL and 7 with sALCL. At present, 20/25 (80%) patients are still in continuous CR (CCR) with a median follow up of 9 months (range 3-41): 10 of them have consolidated the response with a stem cell transplantation (SCT) (4 auto-SCT and 6 allo-SCT) and 10 patients have remained in CR without any other therapy after BV. Among these long-term responders without any consolidation (7 patients with HL and 3 with sALCL), the median follow-up is 12 months (range 3-37); in particular there are 3 patients in CCR after at least 24 months. The global overall survival rate at 68 months is 71% (no patients with sALCL dead) and the median overall survival has not been reached yet. The global progression-free survival rate at 48 months is 30%, the median is achieved at 11,7 months. Toxicity was primarily neurological with peripheral sensory symptoms (30%) and motor neuropathy (5%); the majority was grade 3 in severity (8 patients). This study confirms the safety and the high efficacy of BV that can be considered an effective treatment in patients with relapsed or refractory HL or sALCL. This drug can induce a durable complete response representing a "bridge" to auto-SCT or allo-SCT. However our data show a subset of patients that can be considered "long-term responders", who have remained in CCR without any consolidation after BV.
