Pembrolizumab (PEM) Added to ICE Chemotherapy Results in High Complete Metabolic Response Rates in Relapsed/Refractory Classic Hodgkin Lymphoma (cHL): A Multi-Institutional Phase II Trial

Abstract Introduction: Approximately 30-35% of patients with classic Hodgkin Lymphoma will prove refractory to frontline therapy or relapse subsequently. Traditional second-line chemotherapy regimens including ifosfamide, carboplatin, and etoposide (ICE) result in complete response rates of ~50%. Achievement of complete metabolic response (CMR) assessed by PET/CT imaging prior to autologous hematopoietic stem cell transplant (AHSCT) predicts favorable progression free survival (PFS) and overall survival (OS). PD-1 blockade is a well-established therapeutic strategy for the treatment of cHL. Pembrolizumab (PEM) is a checkpoint inhibitor targeting PD-1 currently FDA approved as monotherapy in relapsed cHL. We hypothesized that PEM in combination with ICE (PEM-ICE) chemotherapy would be a safe and effective regimen that would yield high CMR rates prior to AHSCT. Methods: This single arm, phase II, multi-institutional clinical trial evaluated the addition of PEM to ICE chemotherapy in AHSCT eligible patients with relapsed and refractory cHL (NCT03077828). The regimen consisted of 21 day cycles of PEM 200 mg IV on day 1 with standard ICE including ifosfamide 5 g/m2 with MESNA as a 24hr continuous infusion on day 2, carboplatin AUC 5 IV (max 800 mg) on day 2, and etoposide 100 mg/m2/day IV on days 1 to 3. Two cycles of PEM-ICE were followed by stem cell mobilization/collection. One cycle of PEM 200 mg IV monotherapy was then administered. Our primary endpoint was the rate of CMR on PET/CT (PET2) imaging defined as a Deauville score of ≤ 3. Images were reviewed centrally. An optional third cycle of PEM-ICE was permitted for patients achieving CMR to allow for appropriate timing of AHSCT. Secondary objectives included clinical outcomes (PFS and OS), safety and tolerability, and transplantation related metrics including ability to collect stem cells and time to engraftment. Results: A total of 42 patients were enrolled with 37 patients evaluable for the primary endpoint. Median age was 34 (19-70) with female predominance (n=27, 64%). 16 patients had primary refractory disease. The CMR rate assessed by PET/CT imaging following 2 cycles of PEM-ICE was 86.5% (95% CI, 71.2-95%), meeting our primary endpoint of improvement over historical outcomes to 70%. The PET2 ORR was 97.3% with 11% PR and 2.7% PD. PET2 scores were Deauville 1 in 45% (n=17), Deauville 2 in 27.0% (n=10), Deauville 3 in 8.1% (n=3), Deauville 4 in 13.5% (n=5), and Deauville 5 in 5.4% (n=2). New areas of PET-positivity in two cases were biopsied showing noncaseating granuloma in one case and EBV but no cHL in another. Five patients received the optional third cycle of PEM-ICE chemotherapy with 35 of the 37 evaluable patients proceeding to AHSCT. Seven patients had radiation as part of the conditioning regimen with an additional 4 patients receiving consolidative radiation following transplant. After a median follow up of 27 months, the median PFS was 26.9 months with survival probability at 24 months of 88.2% (Figure 1). Median OS was not reached with too few events but remained 95.1% at 27 months. The addition of PEM to ICE did not impair stem cell mobilization and all patients successfully collected, with 35 (87%) within 2 apheresis sessions (range 1-7). No patients had engraftment delays or failure. Of the 42 patients, all received at least one dose of PEM and were therefore eligible for toxicity analyses. 34 patients (81%) experienced adverse events (AEs) attributed to PEM and 22 patients (52.3%) had grade 3-4 AEs comprised of cytopenias, elevated AST/ALT, hyponatremia, hypophosphatemia, and fatigue. Five patients had severe AEs attributed to PEM which included anemia, back pain, decreased EF, fever, and thrombocytopenia. There were no significant PEM-related autoimmune events that delayed a patient's treatment on protocol. There were two grade 5 toxicities on the protocol including a patient with cardiac arrest during stem cell collection and a patient with acute respiratory distress syndrome attributed to engraftment syndrome. Both were judged "possibly" related to PEM. Conclusions: Pembrolizumab with ICE chemotherapy is a tolerable and efficacious regimen with high CMR rate as assessed by PET/CT. Despite short follow up, patients had excellent PFS and OS in the post-transplant setting. The results support further investigation of PEM-ICE as second-line treatment for AHSCT eligible patients with relapsed and refractory classical Hodgkin lymphoma. Figure 1 Figure 1.

Abstract INTRODUCTION: High-dose salvage chemotherapy followed by autologous stem cell transplantation (Auto-SCT) in chemosensitive patients still remains the standard-of-care treatment for relapsed/refractory classic Hodgkin lymphoma (R/R CHL). As previously reported in a multicenter phase 2 study (Santoro et al., J Clin Oncol, 2016), the BEGEVregimen induces an objective response rate (ORR) >80% in the second-line salvage setting of R/R cHL, thereby resulting a highly effective treatment. Here, we assess efficacy and safety of the BEGEV regimen after extended follow-up (registered at www.clinicaltrials.gov as #NCT01884441). PATIENTS AND METHODS: cHL patients who were refractory to, or have relapsed after first-line chemotherapy were eligible. The primary endpoint was CR rate after 4 cycles of therapy. Secondary endpoints were: ORR, stem cell mobilization activity, and toxicity. Progression free survival (PFS) and overall survival (OS) were also evaluated. The BEGEV regimen consisted of: Bendamustine (90 mg/sqm, days 2-3), Gemcitabine (800 mg/sqm, day 1 and 4) and Vinorelbine (25 mg/sqm, day 1) every 3 weeks for a total of 4 courses. RESULTS: Between September 2011 and March 2014, 59 consecutive patients with relapsed (46%) or refractory (54%) cHL were enrolled. The median age was 33 years (range 18-68). By intention to treat (ITT), after 4 cycles of therapy, 44 (75%) achieved a CR and 5 (8%) a partial response (PR) for an ORR of 83%. One case (2%) showed stable disease (SD), while 8 patients (14%) progressed, and 1 (2%) was not evaluable for response. In univariate analysis, the only factor which resulted associated with a different probability to reach CR was disease status at study entry, with CR being achieved by 84% of relapsed patients and 59% of refractory patients (P=0.031). With a median follow-up of 56 months (range, 3.4-79), the overall patient population (n=59) has an OS of 78% and a PFS of 61%, respectively, without significant difference between relapsed and refractory patients. Fifty-seven out of 59 patients were evaluable for CD34+ cell mobilization. Two of 57 patients (3.5%) experienced CD34+ cell mobilization failure, whereas the planned target dose of CD34+ cells (3×10^6 CD34+ cells/Kg body weight) was successfully harvested in the remaining 55 patients (96.5%). After AutoSCT, engraftment of neutrophils and platelets was recorded on day 11 (range 9-21) and day 12 (range 9 - 26), respectively. Of the 49 responding patients, 43 (73% by intention to treat) proceeded to Auto-SCT (39/43 in CR, 4/5 in PR); the remaining 6 patients did not proceed to Auto-SCT due to mobilization failure (n=2), physician decision (n=2), early relapse (n=1), patient refusal (n=1).After transplant, 4 patients died [pneumonia (n=1), infection (n=1), multi-organ failure (n=1), PD (n=1)] and 7 patients relapsed. No patient has developed secondary leukemia or myelodysplasia. For transplanted patients, the 5-yr OS and PFS are 91% and 77%, respectively. CONCLUSIONS: These 5-year follow-up data demonstrate that BEGEV is a highly effective and safe salvage regimen. Nearly 80% of BEGEV-treated R/R cHL patients who experience an objective response and are addressed to Auto-SCT achieve long-term disease control and may potentially be cured. These data provide a strong rationale for further development of the BEGEV regimen.

Abstract Background: The LY.12 randomized phase 3 clinical trial defined gemcitabine, dexamethasone and cisplatin (GDP) as an effective outpatient salvage chemotherapy regimen in relapsed/refractory (R/R) patients with aggressive lymphomas who are candidates for autologous stem cell transplant (ASCT) (Crump et al. JCO 2014). When the anti-CD20 antibody rituximab (R) was added to GDP, the ORR was 45.6% by CT imaging and 51.9% of patients were able to receive ASCT. Obinutuzumab (O) is a type 2 CD20 antibody that has demonstrated superiority to R in some studies in indolent lymphomas and is active in R-refractory follicular lymphoma. Improvements in the outcome of salvage therapy have tested alternative CD20 antibodies (Van Imhoff, JCO 2017), to date without success. We report a single centre, single arm clinical trial of O-GDP to assess safety and efficacy in R/R aggressive B cell lymphoma. Methods: Transplant eligible patients with DLBCL and transformed indolent lymphoma were treated with O-GDP for two cycles, followed by response assessment by CT. Non-progressors received a third cycle of O-GDP for stem cell mobilization and a PET/CT scan was obtained after stem cell collection. Responders then proceeded to ASCT per investigator decision. O was given at 1000 mg weekly during the first cycle of GDP and then on day 1 of cycles 2 and 3. Responses were determined by Lugano criteria using investigator assessment. The primary outcome was ORR by CT imaging after 2 cycles. The pre-specified statistical analysis stated that the trial will be declared positive if the ORR was >60%, negative if the ORR was <40% and indeterminate if in-between. Secondary outcomes included PET CR rate after 3 cycles of O-GDP and the rate of proceeding to ASCT. Exploratory outcomes included measurements of circulating tumor (ct) DNA during protocol therapy, and analysis of individual mutations. Results: The trial has completed its planned accrual of 30 patients. Median age was 59.5 (range 30 - 70), with 40% female, 70% with DLBCL NOS and 30% with transformed indolent lymphoma (all but one patient having transformed follicular lymphoma). IPI at study entry was 0-1 (20% of patients), 2 (30%) or 3+ (50%). Grade 3 or 4 toxicity was observed in 87% of patients. This was mainly myelosuppression with grade 4 neutropenia (47%) and thrombocytopenia (37%). Other grade 4 adverse events were sepsis (2 patients), febrile neutropenia (1 patient) and hypokalemia (1 patient). No grade 5 events were attributed to study treatment. One additional case of myelodysplastic syndrome caused treatment discontinuation. Events necessitating dose reductions (33% of patients), dose delays (23%) and dose holds (23%) occurred in a total of 57% of patients. At the time of submission, data are evaluable for the primary endpoint in 28 patients. The ORR (CR + PR) by CT imaging after 2 cycles of study therapy was 60.7% (95% CI 40.6-78.5) Overall, 65.5% of patients (95%CI = 45.7%-82.1%) proceeded to ASCT. In addition, 15 patients are evaluable by PET/CT after 3 cycles of O-GDP, with 47% attaining a complete metabolic response (Deauville 1 - 3), 40% a partial metabolic response and 13% with no metabolic response by Lugano criteria. Plasma ctDNA measurements were taken at baseline, after 1 cycle of O-GDP, and at the time of PET/CT. CtDNA quantities will be compared to imaging assessments. Conclusions: O-GDP is an outpatient salvage regimen that enables ASCT in patients with R/R DLBCL. Compared to R-GDP there is a greater frequency of grade 3 - 4 toxicity (O-GDP 87%, R-GDP previously reported at 47%), although the difference is mainly due to cytopenias and can be managed by dose adjustments to the GDP regimen. Further data analysis is required to determine if the trial will meet the primary endpoint of an ORR > 60%. The overall rate of proceeding to ASCT with O-GDP salvage in this trial was 65.5% compared to that previously reported for R-GDP at 51.9%.

Abstract Introduction: The standard treatment for patients with relapsed or refractory (r/r) classical Hodgkin Lymphoma (cHL) is salvage chemotherapy followed by autologous stem cell transplantation (ASCT). The best outcome from the transplant is expected in patients who achieve complete remission (CR) after the salvage chemotherapy. Everolimus is a mammalian target of rapamycin (mTOR) inhibitor that has shown activity and an acceptable toxicity profile in patients with r/r cHL (Johnston PB et al. Am J Hematol 2010; Johnston PB et al. ISHL-9 2013). We therefore aim to improve the CR rate after salvage by an enforced salvage regimen consisting of everolimus plus time-intensified standard DHAP (Dexamethasone, High-Dose AraC [Cytarabine], Cisplatinum). Methods: We conducted a phase I trial of everolimus plus DHAP (ever-DHAP) for patients with r/r cHL eligible for ASCT to assess the recommended phase II dose (RPTD) of oral everolimus in this combination. Everolimus was administered for 14 days in each DHAP cycle starting from one day before DHAP. The second cycle of ever-DHAP was scheduled to start at day 14 of cycle one. Patients received two cycles of ever-DHAP. Everolimus dose levels of 2.5mg, 5mg, 7.5mg and 10mg were assessed in a modified 3+3 design. Generally, dose-limiting toxicity (DLT) was defined as CTCAE grade III/IV toxicity or unsuccessful stem cell mobilization. However, grade III/IV non-hematological toxicities known from DHAP were only counted as DLT from second occurrence in any patient onwards. Grade III/IV hematological toxicities were only counted as DLTs in case of prolonged time to recovery. Restaging by (PET)-CT was performed at day 21 of the second cycle given that the patient had recovered; PET was mandatory for all patients not achieving a CR in the CT scan. The rate of patients experiencing DLTs during 2 cycles of the combination therapy was the primary endpoint of the study. Secondary endpoints included adverse events, tumor related results of therapy or death, treatment administration, time to recovery after end of treatment and stem cell mobilization. Results: 14 patients were recruited between August 2012 and January 2014, all patients received at least one dose of everolimus. The median age was 33.5 years; six were female and eight were male. Eleven patients presented with stage III/IV disease. Overall, treatment was well tolerated. Two patients (both at the 7.5mg level) had a premature treatment termination and did not receive the 2nd cycle, one patient due to ototoxicity of grade I at investigator’s discretion and one patient due to neurotoxicity of grade III/IV. One additional patient (7.5mg cohort) suffered from ototoxicity of grade III/IV between end of treatment and restaging. Both grade III/IV toxicities were pre-defined as known from DHAP, thus they were not considered dose limiting at this first occurrence. No further non-hematological grade III/IV adverse events were reported. All patients but one experienced grade III/IV thrombocytopenia and leukopenia. No DLTs occurred and therefore 10mg of everolimus/day was chosen as RPTD. Duration of induction therapy including restaging after two cycles was 35-54 days. All patients who completed the 1st treatment cycle (n=13) had adequate stem cell mobilization (CD34+ cell count 2.9 - 31.1 x 106/kg; median 10 x 106/kg). So far one death occurred in a patient with pneumococcal sepsis one year after restaging. Responses according to CT scan in 12 patients who received two cycles of ever-DHAP were CR in 3 patients, CR unconfirmed (CRu) in 3 patients, partial remission (PR) in 5 patients and stable disease (SD) in 1 patient. This accounts for a CR/CRu rate of 50% (6/12) and an overall response rate of 92% (11/12). A PET scan was performed in 4 of 6 patients with CR/CRu; all had a negative PET (Deauville 1). In the 6 patients not achieving a CR/CRu 5 patients had a PET scan; 4 were PET positive (2 patients with Deauville 4 and 5 each) and 1 was PET negative (Deauville 1). Conclusions: Ever-DHAP with 10mg everolimus/day is safe and feasible in patients with r/r cHL. Based on the results of this phase I trial a randomized, placebo-controlled trial of ever-DHAP has been initiated and is currently recruiting.

Genome sharing between cancer and normal tissues might imply a similar susceptibility to chemotherapy toxicity. The present study aimed to investigate whether curative potential of doxorubicin, bleomycin, vinblastine, and dacarbazine (ABVD) is predicted by the metabolic response of normal tissues in patients with Hodgkin lymphoma (HL). METHODS: According to current guidelines, 86 patients with advanced-stage (IIB-IVB) HL, prospectively enrolled in the HD0607 trial (NCT00795613), underwent 18 F-fluorodeoyglucose PET/CT imaging at diagnosis and, at interim, after two ABVD courses, to decide regimen maintenance or its escalation. In both scans, myocardial FDG uptake was binarized according to its median value. Death and disease relapse were recorded to estimate progression-free survival (PFS) during a follow-up with median duration of 43.8 months (range 6.97–60). RESULTS: Four patients (4.6%) died, while six experienced disease relapse (7%). Complete switch-off of cancer lesions and cardiac lighting predicted a favorable outcome at Kaplan–Mayer analyses. The independent nature and additive predictive value of their risk prediction were confirmed by the multivariate Cox regression analysis. CONCLUSION: Susceptibility of HL lesions to chemotherapy is at least partially determined by factors featuring the host who developed it.

Abstract Introduction: Autologous stem cell transplants (ASCT) are standard of care for patients with primary refractory or recurrent Hodgkin lymphoma (HL). While transplant results in cure for some patients, others relapse and succumb from their disease. Studies have found high expression of programmed death ligand 1 (PD-L1) in HL cells. The anti-PD-1 monoclonal antibody, nivolumab, has been safe and efficacious in the treatment of relapsed, refractory HL (Ansell et al. 2015). We evaluated the safety and efficacy of nivolumab maintenance therapy post-ASCT in high risk for relapse Hodgkin disease. Methods: Patients with HL with high risk of residual disease following ASCT ( high risk defined as refractory disease, relapse <12 months, or relapse ≥12 months with extranodal disease after frontline therapy) received nivolumab (240 mg IV every 2 weeks) starting 45-180 days post-transplant for a maximum of 6 months of treatment. Patients were followed for AEs through 100 days after the last dose of drug. PET-CT response assessments were performed 1-3 month, 6 month, and 12 month post-ASCT. The primary objective was to evaluate the safety and tolerability of nivolumab as maintenance therapy early after ASCT. The secondary objective was to evaluate progression-free survival (PFS) at 12 months post-transplant. Results: To date, 37 patients were enrolled; median age 36 years; 25 patients (68%) male. The median number of prior systemic regimens was 2 (range 2-4). 25 patients (68%) had relapsed disease, and 12 patients (32%) had primary refractory disease. 18 patients (49%) had extranodal disease at relapse, 6 patients (16%) had B-symptoms at relapse, and 11 patients (30%) had residual disease after salvage, including 10 patients (27%) of whom had 2-3 prior salvage therapies. 22 patients (60%) had received prior brentuximab, and 3 patients (8%) had received prior nivolumab or pembrolizumab. 36 patients received ASCT and 1 patient received tandem ASCT. At the time of data cutoff, 28 patients (76%) had discontinued nivolumab treatment, 22 patients (60%) because they had completed the 6-month treatment course, 4 patients (11%) due to an adverse event (AE) (1 patient each with pain, pneumonitis, rhabdomyolysis, or hypothyroidism), and 2 patients (5%) due to disease progression. The median duration of treatment was 22.1 weeks. 17 patients (46%) experienced a treatment-related AE (TRAE), of which 5 patients (14%) experienced a ≥Grade 3 TRAE. The most common (≥5%) TRAEs were diarrhea, fatigue, bone pain, neutrophil count decreased, pruritus, rash, and vomiting. 2 patients experienced a treatment-related serious AE (pneumonitis, rhabdomyolysis). There were no treatment-related deaths. With a median follow up of 9.2 months, the median PFS and overall survival (OS) have not been reached. The 6 month PFS is 92.1% and the 12-month OS is 100%. There were no differences in OS when stratified based on prior treatment. Conclusions: The use of nivolumab maintenance early after ASCT is safe and tolerable in this high risk patient population. Early efficacy data is promising, but data need to mature to determine the 12 month PFS. Figure 1 Figure 1.

Classic Hodgkin Lymphoma

Abstract Introduction: Patients newly diagnosed with classic Hodgkin lymphoma (CHL) have over 80% chance of remission with first-line chemotherapy, such as ABVD (adriamycin, bleomycin, vinblastine, dacarbazine) regime. However, 10-40% of patients relapse eventually and require salvage therapy. High-dose therapy with autologous stem cell transplantation (ASCT) remains the standard of care for patients with relapsed or refractory CHL, offering a cure rate of around 50%. This may be further improved to around 60% with post-transplant consolidation with brentuximab vedotin (BV). Post-SCT BV consolidation has been offered to all patients, regardless of the risk group, in British Columbia since late 2015. We set out to review the ASCT outcome in CHL patients in the recent decade at our institution. Methods: All adult patients who received ASCT for relapsed or refractory CHL between July 2011 and June 2020 were included in this retrospective analysis. Information pertaining to their demographics, disease characteristics, treatment history, transplant details, clinical outcomes and post-relapse therapy was obtained by review of electronic data. The data cut-off date was June 28, 2021. Survival outcomes were censored at the last known clinic visit for patients without relapse or death during follow up. Survival analysis was performed using Kaplan-Meier survival function and log-rank test. Pearson's chi-square test and ANOVA were used for comparison between cohorts. The statistical program used was Stata® version 16.1 (Texas, USA). Results: 114 patients underwent ASCT for relapsed/refractory CHL. Bulky disease and extranodal involvement were seen in 11% and 40% respectively at relapse. Looking at the 'high risk criteria' as defined in the AETHERA trial: 45/114 (40%) patients had primary refractory CHL, 21/114 (18%) had relapsed within 12 months of completing the front-line chemotherapy and 15/114 (13%) had relapsed beyond one year of completing initial treatment but with an extranodal disease. The most commonly used salvage chemotherapy regime was GDP (gemcitabine, dexamethasone, cisplatin; 111/114; 97%). 10/114 (9%) patients received BV after failing salvage chemotherapy pre-SCT. The median number of lines of therapy pre-SCT was two (range 2-5). 94/108 (98%) had a chemosensitive disease with 35/108 (32%) achieving complete remission. 6/108 (6%) patients had a progressive disease at the time of SCT. For the transplant, all patients had a peripheral blood stem cell source and the conditioning regime was either Carmustine/Etoposide/Cytarabine/Melphalan (76%) or Etoposide/Melphalan (24%). After median follow up of 62.2 months, 50/114 (44%) patients relapsed with median relapse-free survival of 20.2 months (range 0.9 - 113.5) and 16/114 (14%) died. The direct cause of death was lymphoma progression in all but three patients (PJP pneumonia, pulmonary fibrosis, traumatic subdural hematoma). Whereas only 4/51 (8%) patients (2 without relapse) received post-SCT BV consolidation via a compassionate access program between July 2011 and October 2015 (cohort 1), 45/63 (71%) patients (33 in remission) received routine BV consolidation between November 2015 and June 2020 (cohort 2). In cohort 2, 44% had primary refractory CHL compared to 33% in cohort 1 but the number of 'low risk' patients was similar at 29% (Table 1). The most common reason for no post-SCT BV consolidation in cohort 2 was patient refusal (7/18; 40%). Other causes included BV pre-SCT, early disease progression and patient comorbidities. Only 9/42 (21%) patients with available data in cohort 2 completed the planned 16 cycles of BV consolidation. The median number of cycles was 10.5 (range 1-16). The most common reasons for early termination of BV consolidation were peripheral neuropathy (22/33; 67%) and disease progression (9/33; 27%). There was no statistically significant difference in PFS or OS demonstrated between the two cohorts (Graphs 1, 2). Conclusion: After median follow up of 5 years, 86% of patients remain alive and 56% are alive in remission. In British Columbia, post-SCT BV consolidation has been widely adopted with over 70% of patients receiving at least one cycle since late 2015. Successful completion of post-SCT BV consolidation is, however, limited by a high rate of treatment-limiting peripheral neuropathy. Relapse-free survival benefit of routine post-SCT BV consolidation is not demonstrated in this single-centre cohort. Figure 1 Figure 1. Disclosures White: Novartis: Honoraria.

Abstract Background Clinical trials have demonstrated a high level of effectiveness for brentuximab vedotin (BV) for patients with relapsed or refractory classical Hodgkin lymphoma (HL); however, how patients fare in routine clinical practice if their HL recurs after autologous stem cell transplant (ASCT) is less clear. Our primary objective was to characterize overall survival (OS) and progression-free survival (PFS) among a cohort of real-world patients treated with BV after ASCT. The secondary objective was to characterize the outcome of treatment after failure of ASCT or ASCT and BV. Methods We screened the population-based British Columbia Cancer Agency (BCCA) Lymphoid Cancer Database to identify patients with classical HL (excluding lymphocyte predominant HL) who were aged >16 years at initial diagnosis, staged and treated in BC, had primary treatment with ABVD or equivalent chemotherapy, underwent ASCT as part of first treatment for refractory or relapsed disease and relapsed again after ASCT. We excluded patients who have been treated at any time with a checkpoint inhibitor. We determined Kaplan-Meier estimates of overall (OS) and progression free survival (PFS) from the date of the progression that occurred after ASCT and, for those treated with the agent, after subsequent BV. Therapies given in sequence without a pause between therapies were considered part of the same line of therapy. Results Between 1986 and 2015 93 patients experienced recurrence of HL after ASCT. Their median age at initial diagnosis was 30 years and 51% were male. After failure of ASCT 23 (25%) received radiation monotherapy and 61 received chemotherapy (66%), either as a single agent or in various combinations and of these 9 (10%) also received radiation; 6 (6%) received a second transplant (5 allogeneic and 1 repeat ASCT); and 5 refused or were too frail for treatment other than with corticosteroids. The median PFS and OS from the time of relapse after ASCT for these 93 patients were 7.1 (range 0.2-352) and 16.2 months (range 0.2-352), respectively. Of those 93, 17 patients received BV alone or BV+bendamustine at some point following ASCT. The median age of BV-treated patients was 33 years at the time of their original diagnosis and 29% were male. Among those 17 patients, 9 received single agent BV and 8, BV+bendamustine as part of a clinical trial. The median time from ASCT to the start of BV was 27.5 months. Counting ASCT as 2nd line treatment, 10 individuals received BV as 3rd line, 6 as 4th line and 1 as 5th line therapy. For all 17 patients the subsequent median PFS and OS from the time of BV initiation were 5.1 (range 1.5-34.6) and 18.8 months (range 2.4-40.5), respectively. 12 of these patients relapsed again and their subsequent median PFS and OS were 0.6 (range 0.5-29) and 3 (range 0.5-30) months, respectively. All 9 patients who received single agent BV relapsed again at a median of 2 months (range 1.2-9.7); 5 of the 8 patients treated with BV+bendamustine remain in remission 6 to 36 months later. Conclusions These data highlight the poor prognosis for patients with relapsed or refractory cHL, particularly for those whose lymphoma recurs after brentuximab vedotin as well as the highly individualized management of patients whose lymphoma has recurred after ASCT. Future therapies that prevent or significantly delay relapse will help in alleviate the substantial clinical burden due to relapsed and refractory Hodgkin lymphoma.

Radiation-induced sarcoma (RIS) has been reported as a late secondary malignancy following radiotherapy for various types of cancer with a median latency of 10 years. We describe an early RIS that developed in an adolescent within three years of treatment (including PD-L1 check-point inhibitor Nivolumab) of a relapsed classic Hodgkin lymphoma (HL) and was diagnosed post-mortem. The patient died of the progressive RIS that was misleadingly assumed to be a resistant HL based on the positive PET/CT scan. Repetitive tumor biopsies are warranted in cases of aggressive and multi-drug resistant HL to validate imaging findings, ensure correct diagnosis and avoid overtreatment.
