Abstract Novel strategies, such as chemosensitization with targeted agents, that build on the success of standard immunochemotherapy show promise for the treatment of non-Hodgkin lymphoma (NHL). Here, we report a phase 1b study investigating dose escalation of the BCL2 inhibitor, venetoclax, in combination with rituximab or obinutuzumab and cyclophosphamide, doxorubicin, vincristine, and prednisone (R-/G-CHOP) chemotherapy in B-cell NHL. Objectives included safety assessment and determination of a recommended phase 2 dose (RP2D). Fifty-six patients were enrolled, most with follicular lymphoma (43%) or diffuse large B-cell lymphoma (DLBCL; 32%). Dose-limiting toxicities were reported in 3/14 patients at the first venetoclax dose (200 mg/d), after which dosing was changed from daily to 10 days per cycle and escalated to 800 mg. A further reduction to 5 days per cycle occurred at the 800-mg dose level in the G-CHOP arm. Cytopenias were predominant among grade 3/4 events and reported at a higher rate than expected, particularly in the G-CHOP arm; however, safety was manageable. Overall response rates were 87.5% (R-CHOP and G-CHOP combinations); complete response (CR) rates were 79.2% and 78.1%, respectively. Most double-expressor (BCL2+ and MYC+) DLBCL patients (87.5%; n = 7/8) achieved CR. Although the maximum tolerated dose was not reached, the RP2D for venetoclax with R-CHOP was established at 800 mg days 4 to 10 of cycle 1 and days 1 to 10 of cycles 2 to 8; higher doses were not explored, and this dosing schedule demonstrated an acceptable safety profile. This regimen is subsequently being evaluated in first-line DLBCL in the phase 2 portion of the study. This trial was registered at www.clinicaltrials.gov as #NCT02055820.

Abstract Prognosis is poor for patients with relapsed/refractory (R/R) classical Hodgkin lymphoma (cHL) after failure of or who are ineligible for autologous stem cell transplant. We evaluated the efficacy and safety of tislelizumab, an investigational anti-PD-1 monoclonal antibody, in phase 2, single-arm study in Chinese patients with R/R cHL. The primary endpoint was overall response rate as assessed by an independent review committee, according to the Lugano 2014 Classification. Seventy patients were enrolled in the study and received at least one dose of tislelizumab. After median follow-up of 9.8 months, 61 (87.1%) patients achieved an objective response, with 44 (62.9%) achieving a complete response (CR). The estimated 9-month progression-free survival rate was 74.5%. Most common grade ≥3 adverse events (AEs) were upper respiratory tract infection and pneumonitis. Infusion-related reactions occurred in 27 (38.6%) patients, and 27 patients (38.6%) experienced an immune-related AE, the most common of which was thyroid dysfunction. Eleven (15.7%) patients experienced at least one treatment-emergent AE leading to dose interruption or delay. No deaths occurred due to AEs. Treatment of patients with R/R cHL with tislelizumab was generally well tolerated and resulted in high overall response and CR rates, potentially translating into more durable responses for these patients.

e19515 Background: The anti-PD-1 combination therapy significantly improves clinical outcomes in patients with relapsed/refractory classical Hodgkin lymphoma (cHL), and up to 71% of patients who receive decitabine-plus-anti-PD-1 camrelizumab could achieve a complete response. However, a subset of patients is recalcitrant to decitabine-plus-camrelizumab and half of patients might experience disease progression within three years. Effective treatment regimens for those with relapsed or progressive cHL who failed decitabine-plus-camrelizumab are needed. This Phase II study was designed to assess the safety and efficacy of the combination of decitabine-plus-camrelizumab and chidamide, a histone deacetylase inhibitor, in decitabine-plus-camrelizumab resistant cHL patients. Methods: Patients with relapsed/refractory cHL who had primary resistance or progressed/relapsed on decitabine-plus-camrelizumab were enrolled and administrated with chidamide at 10 mg (days 1 to 4) and 20 mg (days 8, 11,15 and 18); plus decitabine at 10 mg (days 1 to 5); and camrelizumab at 200 mg (day 6), every 3 weeks. Safety was assessed by CTCAEv5.0, and antitumor response by PET-CT according to the revised Lugano classification. The primary endpoint was objective response rate. Recruitment is ongoing. This trial is registered with ClinicalTrial.gov number, NCT04233294. Results: Between January 19, 2020, and January 31, 2021, nineteen patients with relapsed/refractory cHL after relapse or progression on decitabine-plus-camrelizumab were enrolled. A median of 20 cycles of prior decitabine-plus-camrelizumab was given (range, 4-28). Fourteen patients completed response evaluation with a median follow-up of 5.7 months. All eligible patients received this triplet-agent regimen with a median of 8 cycles (range, 3 to 12). Thirteen of the fourteen evaluated patients (93%) had an objective response, including six acquiring a complete remission (43%) and seven reaching a partial response (50%). The most common adverse events were leukocytopenia (58%; grade 3: 16%), nausea (53%) and hypertriglyceridemia (26%). No immune-related adverse events were observed. Conclusions: The preliminary result shows a high objective response rate with the combination of chidamide, decitabine and camrelizumab in patients with resistance to decitabine-plus-camrelizumab therapy. The addition of chidamide to decitabine-plus-camrelizumab has an acceptable safety profile, and does not trigger immune-related adverse events. Clinical trial information: NCT04233294.

Abstract Abstract 4777 Understanding the mechanisms of how tumor microenvironment of classical Hodgkin lymphoma (cHL) fosters immune privilege and survival of Hodgkin-Reed-Sternberg (HRS) cells is crucial for the development of new biomarkers and therapy strategies. Recently, infiltrating regulatory T CD4+CD25+FOXP3+ lymphocytes (Tregs) and tumor-associated macrophages CD68+ (TAMs) have been shown to play a role in HRS immune evasion, disease progression and survival. However, data arising from studies of different populations of cHL patients are conflicting. Purpose: In this study, we evaluated the importance of infiltrating Tregs and TAMs in a subset of 130 cHL patients treated in public hospitals in southeast Brazil and correlated these findings with Epstein-Barr virus (EBV) presence in HRS cells. Material and Methods: Tissue microarrays were constructed using diagnostic biopsies available in 130 patients and stained with CD4, CD8, CD25, FOXP3, CD15, CD30, CD68 e LMP1. Quantification of TAMs and Tregs was performed using automated slide scanning and image analysis (Aperio ScanScope XT Slide Scanner and Aperio ImageScope Software with Aperio Positive Pixel Count Sample Macro algorithm). Immunohistochemical scoring ranged from 1 to 4 for the antibodies tested, with higher scores indicating a greater proportion of positive cells. For Tregs and TAMs quantification, score 1 was considered negative (≤ 25 % of Tregs or TAMs) and scores 2, 3, and 4 (more than 25 % of positive cells) were considered positive. All patients underwent similar chemotherapy protocols. For the present study, only cHL patients whose histology could be confirmed and EBV-association established were studied. Results: From the 130 cHL patients selected for this study, 56 (43%) were classified as EBV related and 74 (57%) EBV non-related cHL. The expression of Tregs (CD4/CD25/FOXP3) was more common in the EBV related cHL group (p=0.02). TAMs did not correlate with EBV presence in HRS cells. Response to treatment, either complete response or partial response, and relapse rate were independent of Tregs and TAMs quantification and EBV status. Increased Tregs and TAMs in the tumor microenvironment did not influence event-free survival (EFS) and overall survival (OS). For further analysis, we stratified our patients into 4 groups, according to Tregs and TAMs quantification and EBV status and we still did not find any difference on EFS and OS. Additionally, stratified survival analysis according to age, stage and IPS-risk group did not identify any impact of Tregs and TAMs quantification on EFS and OS. Conclusion: This study demonstrates that increased Tregs and TAMs in the tumor microenvironment of cHL patients neither correlate with treatment response nor survival. Additionally, increased Tregs correlated with EBV presence in HRS cells. It is well known that the incidence of EBV-related cHL in developing countries is different from that in developed ones, as well as the severity of the disease at presentation, with advanced disease being more common at diagnosis. Our results, although different from those recently published, probably reflect the reality of the Brazilian population enrolled in the public health system, highlighting the importance of studying the same disease and their potential biomarkers within different populations. Disclosures: No relevant conflicts of interest to declare.

AbstractHodgkin lymphoma is a highly curable disease. Although most patients achieve complete response following frontline therapy, key unmet clinical needs remain including relapsed/refractory disease, treatment-related morbidity, impaired quality of life and poor outcome in patients older than 60 years. The incorporation of novel therapies, including check point inhibitors and antibody–drug conjugates, into the frontline setting, sequential approaches, and further individualized treatment intensity may address these needs. We summarize the current treatment options for patients with classical Hodgkin lymphoma from frontline therapy to allogeneic hematopoietic stem cell transplantation and describe novel trials in the field.

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 The KEYNOTE-013 study was conducted to evaluate pembrolizumab monotherapy in hematologic malignancies; classical Hodgkin lymphoma (cHL) was an independent expansion cohort. We present long-term results based on >4 years of median follow-up for the cHL cohort. The trial enrolled cHL patients who experienced relapse after, were ineligible for, or declined autologous stem cell transplantation and experienced progression with or did not respond to brentuximab vedotin. Patients received IV pembrolizumab 10 mg/kg every 2 weeks for up to 2 years or until confirmed progression or unacceptable toxicity. Primary end points were safety and complete response (CR) rate by central review. Enrolled patients (N = 31) had received a median of 5 therapies (range, 2 to 15). After a median follow-up of 52.8 months (range, 7.0 to 57.6 months), CR rate was 19%, and median duration of response (DOR) was not reached; 24-month and 36-month DOR rates were both 50% by the Kaplan-Meier method. Median overall survival was not reached; 36-month overall survival was 81%. Six patients (19%) experienced grade 3 treatment-related adverse events (AEs); there were no grade 4 or 5 treatment-related AEs. With long-term follow-up among a heavily pretreated cohort, pembrolizumab had a favorable safety profile; some patients maintained long-term response with pembrolizumab years after end of treatment. This trial was registered at www.clinicaltrials.gov as #NCT01953692.

Abstract The 9p24.1 chromosomal alteration in classical Hodgkin lymphoma (cHL) is associated with increased expression of programmed death ligand 1 (PD-L1)/PD-L2 and an immunosuppressive tumor microenvironment. Blockade of PD-L1/PD-1 interactions with avelumab (anti–PD-L1) is hypothesized to restore antitumor immunity. JAVELIN Hodgkins was a phase 1b, multiple-dose, open-label, randomized, parallel-arm trial of avelumab in patients with relapsed/refractory (R/R) cHL. Primary end points included avelumab target occupancy by dose/schedule in peripheral blood immune cells and pharmacokinetic parameters. Secondary end points included safety and antitumor activity. Four dose levels and 2 dosing schedules were investigated: 70, 350, and 500 mg administered every 2 weeks; 500 mg every 3 weeks; and 10 mg/kg every 2 weeks. Thirty-one patients with R/R cHL were randomized; 9 (29.0%) and 20 (64.5%) had received 3 or ≥4 prior anticancer treatments, respectively. Target occupancy of >90% was observed across all treatment arms, throughout the dosing interval. Avelumab pharmacokinetic data were similar to those previously reported. The most common treatment-related adverse events of any grade were infusion-related reaction (30.0%), nausea (20.0%), increased alanine aminotransferase and rash (16.7% each), and fatigue (13.3%). The objective response rate (ORR) in all randomized patients was 41.9%, with a complete response rate of 19.4%; ORR in those with prior allogeneic hematopoietic stem cell transplant (allo-HSCT) was 55.6%. Due to decreased use of allo-HSCT in patients with R/R cHL, the expansion phase enrolling post–allo-HSCT patients was terminated. Avelumab was tolerable and demonstrated antitumor activity in heavily pretreated patients with cHL, suggesting that PD-L1 blockade may be sufficient for therapeutic benefit in cHL. This trial was registered at www.clinicaltrials.gov as #NCT02603419.

Classical Hodgkin Lymphoma

Introduction. Hemophagocytic lymphohistiocytosis (HLH) is a rare hyperinflammatory syndrome that can be associated with inherited genetic mutations, malignancy, autoimmune disorders, and viral infections. Though the pathogenesis is not fully known, HLH is understood to be a reactive process in the setting of uncontrolled activation of macrophages, CD8+ cytotoxic lymphocytes, and other immune cells. Hallmark clinicopathological features of HLH include fevers, cytopenias, hepatosplenomegaly, and hemophagocytosis in the bone marrow.Case Presentation. A previously healthy 28-year-old Caucasian male presented with a one-month history of persistent fever, night sweats, and unintentional weight loss. He was diagnosed with classical Hodgkin Lymphoma (HL) by core-needle biopsy of an axillary lymph node. Both bone marrow involvement by HL and hemophagocytosis were seen on subsequent bone marrow biopsy. Other findings included pancytopenia, splenomegaly, and elevated serum ferritin. Extensive work-up for autoimmune and infectious etiologies was unremarkable. The patient had a complete response after chemotherapy with Adriamycin, bleomycin, vincristine, and dacarbazine.Conclusion. This report documents the exceedingly uncommon association between HLH and HL. HLH is a hyperinflammatory syndrome with high mortality, so it is imperative to identify and treat the underlying cause for secondary HLH. Malignancy-associated HLH should be considered in the differential diagnosis for cancer patients who present with fever, cytopenias, and splenomegaly.
