ABSTRACT
BACKGROUND: Ibrutinib, a Bruton's tyrosine kinase inhibitor, may have clinical benefit when administered in combination with bendamustine and rituximab and followed by rituximab maintenance therapy in older patients with untreated mantle-cell lymphoma. METHODS: We randomly assigned patients 65 years of age or older to receive ibrutinib (560 mg, administered orally once daily until disease progression or unacceptable toxic effects) or placebo, plus six cycles of bendamustine (90 mg per square meter of body-surface area) and rituximab (375 mg per square meter). Patients with an objective response (complete or partial response) received rituximab maintenance therapy, administered every 8 weeks for up to 12 additional doses. The primary end point was progression-free survival as assessed by the investigators. Overall survival and safety were also assessed. RESULTS: Among 523 patients, 261 were randomly assigned to receive ibrutinib and 262 to receive placebo. At a median follow-up of 84.7 months, the median progression-free survival was 80.6 months in the ibrutinib group and 52.9 months in the placebo group (hazard ratio for disease progression or death, 0.75; 95% confidence interval, 0.59 to 0.96; P = 0.01). The percentage of patients with a complete response was 65.5% in the ibrutinib group and 57.6% in the placebo group (P = 0.06). Overall survival was similar in the two groups. The incidence of grade 3 or 4 adverse events during treatment was 81.5% in the ibrutinib group and 77.3% in the placebo group. CONCLUSIONS: Ibrutinib treatment in combination with standard chemoimmunotherapy significantly prolonged progression-free survival. The safety profile of the combined therapy was consistent with the known profiles of the individual drugs.

Previous analyses of the phase 2 KEYNOTE-170 (NCT02576990) study demonstrated effective antitumor activity and acceptable safety of pembrolizumab 200 mg given every 3 weeks for up to 35 cycles (â¼2 years) in patients with relapsed/refractory (R/R) primary mediastinal B-cell lymphoma (PMBCL) whose disease progressed after or who were ineligible for autologous stem cell transplantation. The end points included objective response rate (ORR), progression-free survival (PFS), and duration of response (DOR) according to the investigator per 2007 Response Criteria; overall survival (OS); and safety. In this final analysis, median duration of follow-up was 48.7 months (range, 41.2-56.2). The ORR was 41.5% (complete response, 20.8%; partial response, 20.8%). The median DOR was not reached; no patients who achieved a complete response progressed at the data cutoff. The median PFS was 4.3 months; the 4-year PFS rate was 33.0%. The median OS was 22.3 months; the 4-year OS rate was 45.3%. At the data cutoff, 30 patients (56.6%) had any-grade treatment-related adverse events (AEs); the most common were neutropenia, asthenia, and hypothyroidism. Grade 3/4 treatment-related AEs occurred in 22.6% of the patients; no grade 5 AEs occurred. After 4 years of follow-up, pembrolizumab continued to provide durable responses, with promising trends for long-term survival and acceptable safety in R/R PMBCL.

Glofitamab is a CD3xCD20 bi-specific antibody with two fragments directed to the CD20 antigen and a single CD3-binding fragment. Encouraging response and survival rates were recently reported in a pivotal phase II expansion trial conducted in patients with relapsed/refractory (R/R) B-cell lymphoma. However, the real-world data of patients of all ages with no strict selection criteria are still lacking. Herein, this retrospective study aimed to evaluate the outcomes of diffuse large B-cell lymphoma (DLBCL) patients who received glofitamab via compassionate use in Turkey. Forty-three patients from 20 centers who received at least one dose of the treatment were included in this study. The median age was 54 years. The median number of previous therapies was 4, and 23 patients were refractory to first-line treatment. Twenty patients had previously undergone autologous stem cell transplantation. The median follow-up time was 5.7 months. In efficacy-evaluable patients, 21% and 16% of them achieved complete response and partial response, respectively. The median response duration was 6.3 months. The median progression-free survival (PFS) and overall survival (OS) was 3.3 and 8.8 months, respectively. None of the treatment-responsive patients progressed during the study period, and their estimated 1-year PFS and OS rate was 83%. The most frequently reported toxicity was hematological toxicity. Sixteen patients survived, while 27 died at the time of the analysis. The most common cause of death was disease progression. One patient died of cytokine release syndrome during the first cycle after receiving the first dose of glofitamab. Meanwhile, two patients died due to glofitamab-related febrile neutropenia. This is the largest real-world study on the effectiveness and toxicity of glofitamab treatment in R/R DLBCL patients. The median OS of 9 months seems promising in this heavily pretreated group. The toxicity related mortality rates were the primary concerns in this study.
ABSTRACT
Allogeneic hematopoietic stem cell transplantation (AHSCT) is a promising strategy for treatment of heavily pretreated mycosis fungoides/Sezary syndrome (MF/SS). Herein, we aimed to evaluate the outcomes of AHSCT for heavily pretreated patients with MF/SS retrospectively. This analysis included consecutive 19 patients with MF/SS who received 20 AHSCT between 2012-2021 in our transplant center. Eight patients have been previously reported. Fifteen patients had diagnosis of MF and referred to SS in five patients. In our cohort, all cases had advanced disease (stages IIB: n = 1, IIIA: n = 7; IIIB: n = 4, IVA: n = 4, and IVB: n = 3). Nine patients (47.4%) had developed large cell transformation. Only two patients received AHSCT in complete response, one very good partial response and two partial response while the others had progressive disease (n = 15) before transplant. Seven (35%) patients were alive at the time of analysis, with a median follow up of 10.5 months (range, 0.3-113 months) after AHSCT. Nine patients (47.4%) died without disease relapse or progression. Non-relapse mortality was 35.9% at 1 year and 26.9% at 3 years and thereafter. For all patients the probability of overall survival was 48.5% and 32.3% at 1- and 5-year post-transplant, respectively. AHSCT for MF/SS resulted in an estimated progression free survival of 45.4% at 1 year. Given the poor prognosis of patients not receiving transplants and in the absence of curative non-transplantation therapies, our results support that AHSCT is able to effectively rescue 32.3% of the population of transplant eligible, heavily pretreated patients in 5 years.

BACKGROUND: PD-1 blockade via pembrolizumab monotherapy has shown antitumour activity and toxicity in patients with relapsed or refractory classical Hodgkin lymphoma. Here, we present interim analyses from the KEYNOTE-204 study evaluating pembrolizumab versus brentuximab vedotin for relapsed or refractory classical Hodgkin lymphoma. METHODS: In this randomised, open-label, phase 3 study, patients aged 18 years or older with relapsed or refractory classical Hodgkin lymphoma with measurable disease and an Eastern Cooperative Oncology Group performance status of 0 or 1 who were ineligible for or had relapsed after autologous haematopoietic stem-cell transplantation (HSCT) were enrolled at 78 hospitals and cancer centres in 20 countries and territories. Patients were randomly assigned (1:1) with an interactive voice response system to pembrolizumab 200 mg intravenously every 3 weeks or brentuximab vedotin 1·8 mg/kg intravenously every 3 weeks. Randomisation was stratified by previous autologous HSCT and status after front-line therapy. Results from the second interim analysis are presented here, with a database cutoff of Jan 16, 2020. The dual primary endpoints assessed in the intention-to-treat population were progression-free survival as assessed by blinded independent central review, and overall survival (not analysed at this interim analysis). Safety was assessed in all patients who received at least one dose of the study drug. This study is registered with ClinicalTrials.gov, NCT02684292. Recruitment for this trial is closed. FINDINGS: Between July 8, 2016, and July 13, 2018, 151 patients were randomly assigned to pembrolizumab and 153 to brentuximab vedotin. After a median time from randomisation to data cutoff of 25·7 months (IQR 23·4-33·0), median progression-free survival was 13·2 months (95% CI 10·9-19·4) for pembrolizumab versus 8·3 months (5·7-8·8) for brentuximab vedotin (hazard ratio 0·65 [95% CI 0·48-0·88]; p=0·0027). The most common grade 3-5 treatment-related adverse events were pneumonitis (six [4%] of 148 patients in the pembrolizumab group vs one [1%] of 152 patients in the brentuximab vedotin group), neutropenia (three [2%] vs 11 [7%]), decreased neutrophil count (one [1%] vs seven [5%]), and peripheral neuropathy (one [1%] vs five [3%]). Serious treatment-related adverse events occurred in 24 (16%) of 148 patients receiving pembrolizumab and 16 (11%) of 152 patients receiving brentuximab vedotin. One treatment-related death due to pneumonia occurred in the pembrolizumab group. INTERPRETATION: Pembrolizumab showed statistically significant and clinically meaningful improvement in progression-free survival compared with brentuximab vedotin, with safety consistent with previous reports. These data support pembrolizumab as the preferred treatment option for patients with relapsed or refractory classical Hodgkin lymphoma who have relapsed post-autologous HSCT or are ineligible for autologous HSCT.

BACKGROUND: Copanlisib, an intravenous pan-class I PI3K inhibitor, showed efficacy and safety as monotherapy in patients with relapsed or refractory indolent non-Hodgkin lymphoma who had received at least two therapies. The CHRONOS-3 study aimed to assess the efficacy and safety of copanlisib plus rituximab in patients with relapsed indolent non-Hodgkin lymphoma. METHODS: CHRONOS-3 was a multicentre, double-blind, randomised, placebo-controlled, phase 3 study in 186 academic medical centres across Asia, Australia, Europe, New Zealand, North America, Russia, South Africa, and South America. Patients aged 18 years and older with an Eastern Cooperative Oncology Group performance status of no more than 2 and histologically confirmed CD20-positive indolent B-cell lymphoma relapsed after the last anti-CD20 monoclonal antibody-containing therapy and progression-free and treatment-free for at least 12 months, or at least 6 months for patients unwilling or unfit to receive chemotherapy, were randomly assigned (2:1) with an interactive voice-web response system via block randomisation (block size of six) to copanlisib (60 mg given as a 1-h intravenous infusion on an intermittent schedule on days 1, 8, and 15 [28-day cycle]) plus rituximab (375 mg/m2 given intravenously weekly on days 1, 8, 15, and 22 during cycle 1 and day 1 of cycles 3, 5, 7, and 9) or placebo plus rituximab, stratified on the basis of histology, progression-free and treatment-free interval, presence of bulky disease, and previous treatment with PI3K inhibitors. The primary outcome was progression-free survival in the full analysis set (all randomised patients) by masked central review. Safety was assessed in all patients who received at least one dose of any study drug. This study is registered with ClinicalTrials.gov, NCT02367040 and is ongoing. FINDINGS: Between Aug 3, 2015, and Dec 17, 2019, 652 patients were screened for eligibility. 307 of 458 patients were randomly assigned to copanlisib plus rituximab and 151 patients were randomly assigned to placebo plus rituximab. With a median follow-up of 19·2 months (IQR 7·4-28·8) and 205 total events, copanlisib plus rituximab showed a statistically and clinically significant improvement in progression-free survival versus placebo plus rituximab; median progression-free survival 21·5 months (95% CI 17·8-33·0) versus 13·8 months (10·2-17·5; hazard ratio 0·52 [95% CI 0·39-0·69]; p<0·0001). The most common grade 3-4 adverse events were hyperglycaemia (173 [56%] of 307 patients in the copanlisib plus rituximab group vs 12 [8%] of 146 in the placebo plus rituximab group) and hypertension (122 [40%] vs 13 [9%]). Serious treatment-emergent adverse events were reported in 145 (47%) of 307 patients receiving copanlisib plus rituximab and 27 (18%) of 146 patients receiving placebo plus rituximab. One (<1%) drug-related death (pneumonitis) occurred in the copanlisib plus rituximab group and none occurred in the placebo plus rituximab group. INTERPRETATION: Copanlisib plus rituximab improved progression-free survival in patients with relapsed indolent non-Hodgkin lymphoma compared with placebo plus rituximab. To our knowledge, copanlisib is the first PI3K inhibitor to be safely combined with rituximab and the first to show broad and superior efficacy in combination with rituximab in patients with relapsed indolent non-Hodgkin lymphoma.

Classical Hodgkin lymphoma (cHL) is considered a curable disease; however, approximately one-third of responders experience disease relapse following first-line therapy. Several studies have shown the efficacy of brentuximab vedotin (BV) in patients with relapsed/refractory HL. We present a retrospective analysis of 58 patients with relapsed/refractory HL treated with BV in a named patient program from 11 centers. The median follow-up duration was 20 (range, 4-84) months. The best overall response rate was 64% (complete response [CR], 31%; partial response [PR], 33%). The 5-year progression-free survival (PFS) and overall survival (OS) rates were 12% (95% confidence interval [CI], 0.05-0.22) and 26% (95% CI, 0.16-0.38), respectively. Among patients who achieved CR, the estimated 5-year PFS and OS rates were 32% (95% CI, 0.13-0.54) and 60% (95% CI, 0.33-0.78), respectively. A total of 26 patients underwent subsequent stem cell transplantation. The 5-year PFS and OS rates for 10 patients who had consolidative stem cell transplantation were 28% and 30%, respectively. Twenty-seven patients required further therapy following BV. At the time of the analysis, 12 patients (21%) were alive. Five patients (9%) had long-term remission after achieving CR with BV monotherapy, with a median PFS of 76 months. Three of them (5%) did not receive any other treatment following BV and their median PFS was 75 months. Our long-term results showed that a small subset of patients with relapsed/refractory cHL may benefit from and even be cured with BV monotherapy.

Classical Hodgkin lymphoma (cHL) is considered a curable disease; however, in approximately one-third of the responding patients, the disease relapses following completion of therapy. One of the drugs that have been approved for the treatment of relapsed/refractory cHL is nivolumab, an immune check point inhibitor that shows its effects by blocking the programmed death 1 (PD-1) receptor. In this study, we present a retrospective "real-life" analysis of the usage of nivolumab in patients with relapsed/refractory cHL that have joined the named patient program (NPP) for nivolumab, reflecting 4 years of experience in the treatment of relapsed/refractory cHL. We present a retrospective analysis of 87 patients (median age, 30) that participated in the NPP in 24 different centers, who had relapsed/refractory cHL and were consequently treated with nivolumab. The median follow-up was 29 months, and the median number of previous treatments was 5 (2-11). In this study, the best overall response rate was 70% (CR, 36%; PR, 34%). Twenty-eight of the responding patients underwent subsequent stem cell transplantation (SCT). Among 15 patients receiving allogeneic stem cell transplantation, 9 patients underwent transplantation with objective response, of which 8 of them are currently alive with ongoing response. At the time of analysis, 23 patients remained on nivolumab treatment and the rest discontinued therapy. The main reason for discontinuing nivolumab was disease progression (n = 23). The safety profile was acceptable, with only nine patients requiring cessation of nivolumab due to serious adverse events. The 24-month progression-free and overall survival rates were 58.5% (95% CI, 0.47-0.68) and 78.7% (95% CI, 0.68-0.86), respectively. Eighteen patients died during the follow-up and only one of these was regarded to be treatment-related. With its efficacy and its safety profile, PD-1 blockers became an important treatment option in the heavily pretreated cHL patients.

OBJECTIVE: We evaluated ibrutinib, a once-daily inhibitor of Bruton's tyrosine kinase, combined with bortezomib and dexamethasone in patients with relapsed or relapsed/refractory multiple myeloma who had received 1-3 prior therapies. METHODS: This was a phase 2, single-arm, open-label, multicentre study (NCT02902965). The primary endpoint was progression-free survival (PFS). RESULTS: Seventy-six patients were enrolled; 74 received ≥1 dose of study treatment. After median follow-up of 19.6 months, median PFS was 8.5 months (95% CI: 6.2-10.8); median overall survival was not reached. Overall response rate was 57% (95% CI: 45-68), and median duration of response was 9.5 months (95% CI: 6.9-10.6). Grade 3/4 AEs occurred in 73% of patients and fatal AEs occurred in 15% of patients. Incidence of major haemorrhage was 5%; one patient died from cerebral haemorrhage. After an observed increased incidence of serious (42%) and fatal (11%) infections, enrolment was suspended to implement risk-minimisation measures. The safety profile was otherwise consistent with known safety profiles of the individual drugs. CONCLUSION: Ibrutinib combined with bortezomib and dexamethasone elicited clinical responses. However, efficacy assessments conducted at potential restart of enrolment indicated that the targeted PFS could not be reached with additional patient enrolment, and the study was terminated.

Safety profiles of oral PI3K inhibitors have resulted in US FDA black box warnings regarding fatal/serious toxicities. The approved intravenous PI3K inhibitor copanlisib has low incidence of severe toxicities and no black box warnings, but chronic treatment effects were unknown. We provide an update on safety and efficacy of copanlisib with a minimum 2-year follow-up of the CHRONOS-1 study. A total of 142 patients with histologically confirmed indolent B-cell lymphoma who had relapsed after or were refractory to ≥2 prior treatments received intravenous copanlisib 60 mg on days 1, 8, and 15 (28-day cycle). The primary efficacy endpoint was objective response rate (ORR) after ≥4 cycles (independent assessment). The predominant histology was follicular lymphoma (n = 104). The ORR was 60.6% (seven additional complete responses since primary analysis). Secondary endpoints of median duration of response, progression-free survival, and overall survival were 14.1 months (median follow-up, 16.1 months), 12.5 months (median follow-up, 14.0 months), and 42.6 months (median follow-up, 31.5 months), respectively. Median safety follow-up was 6.7 months; 26% of patients received treatment for >1 year. Common treatment-emergent adverse events (TEAEs) (all grade/grade 3/grade 4) were transient hyperglycemia (50.0%/33.1%/7.0%), diarrhea (35.2%/8.5%/0%), transient hypertension (29.6%/23.9%/0%), and neutropenia (28.9%/9.2%/14.8%). Serious AEs were largely unchanged, with no new cases of pneumonitis (4.2%), diarrhea (2.8%), or grade 5 events. Note, TEAEs showed no evidence for increased incidence or worsening following longer exposure in patients treated >1 year. Long-term follow-up of patients with relapsed/refractory indolent B-cell lymphoma treated with intravenous copanlisib demonstrated durable, enhanced responses without evidence of worsening TEAEs, as reported for orally administered PI3K inhibitors.

INTRODUCTION: Thyroid dysfunction (TD) is one of the major endocrinopathies shown after allogeneic hematopoietic stem cell transplantation over the long term. The incidence and the risk factors for TD have varied widely. PATIENTS AND METHODS: Two hundred and fifty-nine patients with pre-transplant normal thyroid function tests who survived at least 1 year after allo-HSCT between 2006-2016 were included in the study. RESULTS: Sixty-four patients (25%) developed TD at median of 34 months (range, 1-112 months). Hypothyroidism was detected in 32 patients (12%): 5 patients had primary hypothyroidism, and subclinical hypothyroidism occurred in 27 patients. 18 patients (7%) were diagnosed with hyperthyroidism: 2 patients (0.07%) were treated for primary hyperthyroidism, and 16 patients (6%) were followed for subclinical hyperthyroidism. Euthyroid sick syndrome occurred in 14 cases. None of the patients with thyroid dysfunction developed secondary thyroid malignancy. Receiving high-dose TBI (P = .001) was found to be significant risk for hypothyroidism; older age than median (P = .01) and pre-transplant active disease (P < .0001) were related to hyperthyroidism. CONCLUSIONS: Thyroid dysfunction, mostly hypothyroidism, is a long-term complication after allo-HSCT in 25% of patients. Older age, pre-transplant active disease, and receiving TBI are among the risk factors. Sustained long-term monitoring of thyroid function test should be considered post allo-HSCT.

Some patients with relapsed/refractory Hodgkin lymphoma (HL) are not considered suitable for stem cell transplant (SCT) and have a poor prognosis. This phase IV study (NCT01990534) evaluated brentuximab vedotin (1·8 mg/kg intravenously once every 3 weeks) in 60 patients (aged ≥18 years) with CD30-positive relapsed/refractory HL, a history of ≥1 prior systemic chemotherapy regimen, who were considered unsuitable for SCT/multi-agent chemotherapy. Primary endpoint was overall response rate (ORR) per independent review facility (IRF). Secondary endpoints included duration of response (DOR), progression-free survival (PFS) per IRF, overall survival (OS), proportion proceeding to SCT and safety. The ORR was 50%, with 12% CR; 47% proceeded to SCT. Median DOR was 4·6 months and median duration of CR was 6·1 months. After a median follow-up of 6·9 and 16·6 months, median PFS and OS were 4·8 months (95% confidence interval, 3·0-5·3) and not reached, respectively; estimated OS rate was 86% at 12 months. Most common adverse events (≥10%) were peripheral neuropathy (35%), pyrexia (18%), diarrhoea and neutropenia (each 10%). Brentuximab vedotin showed notable activity with a safety profile consistent with known toxicities, and may act as a bridge to SCT, enabling high-risk patients who achieve suboptimal response to frontline/salvage chemotherapy/radiotherapy to receive potentially curative SCT.

We evaluated 979 patients for the development of post-transplant lymphoproliferative disease (PTLD) and solid malignancies after allogeneic hematopoietic stem cell transplantations (allo-HSCT) as a late complication. We found 15 (1.5%) subsequent malignancies; three of these malignancies were PTLD, and twelve were solid tumors. The median time from allo-HSCT to the development of PTLD was 9 (3-20) months and that from allo-HSCT to the development of solid tumors was 93 (6-316) months. The cumulative incidence of evolving subsequent malignancy in patients was 1.3% (±0.5 SE) at 5 years and 3.9% (±1.2 SE) at 10 years. The cumulative incidence of developing subsequent malignancy in patients with benign hematological diseases as the transplant indication was 7.4%±4.2 SE at 5 years. More subsequent malignancy developed in patients having ≥1 year chronic graft-vs-host disease (GVHD; 3.7% in ≥1 year chronic GVHD and 0.7% in <1 year chronic GVHD patient groups, P=.002). Subsequent epithelial tumor risk was higher in ≥1 year chronic GVHD patients than <1 year (3.7% vs 0.1%, P<.001). In multivariate analysis, benign hematological diseases as transplant indication (RR: 5.6, CI 95%: 1.4-22.3, P=.015) and ≥1 year chronic GVHD (RR: 7.1, 95% CI: 2.3-22.5, P=.001) were associated with the development of subsequent malignancy.

Post-transplant erythrocytosis is an infrequent complication and has been reported after allogeneic hematopoietic stem cell transplantation (allo-HSCT) in aplastic anemia, acute myeloid leukemia, and chronic myeloid leukemia. The pre-disposing factors and treatment are not clearly defined. We present 11 post-transplant erythrocytosis cases. More studies should be conducted to distinguish the pathogenesis and follow-up for this rare complication.

Copanlisib, a pan-class I phosphatidylinositol 3-kinase inhibitor with predominant activity against the α and δ isoforms, previously demonstrated durable responses as monotherapy and improved progression-free survival (PFS) in combination with rituximab in patients with relapsed indolent non-Hodgkin lymphoma (iNHL). CHRONOS-4 was a phase 3, randomized, double-blind, placebo-controlled study to investigate the efficacy and safety of copanlisib in combination with standard immunochemotherapy in patients with relapsed iNHL. Patients (n=524) were randomized (1:1) to copanlisib (60 mg IV) plus immunochemotherapy (rituximab and bendamustine [R-B] or placebo plus R-B). Copanlisib/placebo were administered with R-B (days 1, 8, and 15 of each 28-day cycle) for ≤6 cycles and as monotherapy from cycle 7 up to 12 months. The primary study endpoint was PFS. Median exposure was 8.5 months (0.2-12.9) for copanlisib plus R-B and 11.4 months (0.1-12.6) for placebo plus R-B. Median PFS was 32.9 months (95% CI, 24.4-38.6) for copanlisib plus R-B and 33.3 months (95% CI, 27.8-42.8) for placebo plus R-B (HR, 1.13 [95% CI, 0.88-1.44]; P=0.83). No differences between treatment arms were observed in overall survival (data not yet mature), objective response rate, and duration of response for the overall population or individual histology types. Overall, copanlisib plus R-B was associated with higher rates of serious treatment-emergent adverse events (TEAEs), grade 4 and 5 TEAEs, and treatment discontinuation. A number of serious TEAEs were infections. Overall, copanlisib plus R-B did not provide clinical benefit versus placebo plus R-B and was associated with worse tolerability in patients with relapsed iNHL. ClinicalTrials.gov: NCT02626455.
ABSTRACT
INTRODUCTION: Standard consolidation for primary diffuse large B cell lymphoma (DLBCL) of the central nervous system (CNS) (PCNSL) is not established. This single center, retrospective observational study aims to define the outcomes of consolidative high dose chemotherapy and autologous stem cell transplantation (HDC/ASCT) in patients with PCNSL and isolated secondary CNS DLBCL (SCNSL) and evaluate the prognostic factors. PATIENTS AND METHODS: All consecutive patients performed an HDC/ASCT for PCNSL or isolated SCNSLs between October 2012 and February 2022 were identified. Primary endpoints were progression-free survival (PFS) and overall survival (OS). RESULTS: Among 35 patients included, 28 had PCNSL and 7 had isolated SCNSL. Median age was 51 (16-78). Males constituted 48.6%. Median follow-up after HDC/ASCT was 42.0 months. MATRIX (51.4%) and TEAM (80.0%) were the most frequent regimens of induction and conditioning, respectively. OS and PFS 1- and 2-year after HDC/ASCT were 68.0%, 57.0%, 58.0%, 48.0%, respectively. Increasing age, poor performance and comorbidities were associated with lower OS and PFS and higher non-relapse mortality (NRM). Complete response (CR) 1 at HDC/ACST was independently associated with higher OS and PFS [hazard ratio (HR): 4.67 and 6.99, respectively]. CONCLUSION: In patients < 60 years consolidative HDC/ASCT yields promising OS and PFS. Patients ≥ 60 years may less likely benefit from consolidative HDC/ASCT and should be studied further in trials of novel agents, lower doses of consolidative radiotherapy and dose-adjusted conditioning regimens. Not only age, but also comorbidities, clinical performance and response to induction correlate with outcomes. Patients with isolated SCNSL may achieve similar outcomes.

Background: Eltrombopag has an off-label indication for haematopoietic cell transplantation in patients experiencing delayed thrombocyte recovery and/or thrombocytopaenia. Aims: To present our centre's experience of using this agent not only for post- haematopoietic cell transplantation thrombocytopaenia but also for poor graft functioning in the post-haematopoietic cell transplantation setting. Study Design: Retrospective cross-sectional study. Methods: Thirty-nine patients who had persistent cytopaenia following haematopoietic cell transplantation and treated with eltrombopag at our centre between October 2011 and December 2021 were retrospectively identified. During this period, 9 (23.1%) and 30 (76.9%) patients who underwent allogeneic transplantations, respectively, received eltrombopag. Results: The female-to-male ratio was 12:27, and the median transplant age was 49 (18-70) years. Eight (20.5%) patients had isolated thrombocytopaenia, 19 (49.4%) had bi-lineage cytopaenia and 12 (30.1%) had pancytopaenia. Patients received a median of 50 mg/day (25-150 mg/day) of eltrombopagfor a median duration of 82 (24-386) days. Nine (23.1%) patients had autologous haematopoietic cell transplantation, and 30 (76.9%) had allogeneic haematopoietic cell transplantation (14 unrelated, 9 sibling and 7 haploidentical). The median donor age was 32 (20-67) years. The median follow-up was 16.4 (1.8-84.3) months. The median pre-treatment platelet count was 11x109/l (1-23), which increased to 41x109/l (6-150). The median platelet count increment was 29.5x109/l (p = 0.001). The pre-treatment median neutrophil count was 1.19x109/l (0.39-5.1), which increased to 2.35 x109/l (0.1-5.33) (p = 0.05), and the pre-treatment median haemoglobin was 8.3 (6.2-14) g/dl, which increased to 10 (6.2-14) g/dl (p = 0.001) with eltrombopag. No eltrombopag-related hepatotoxicity occurred; however, 1 (2.6%) patient failed to continue treatment because of two consecutive episodes of deep venous thrombosis. Six (15.4%) patients were unresponsive to eltrombopag and dependent on blood product transfusions. After a median time of 82 days, 61.5% of the patients discontinued eltrombopag successfully. Conclusion: The results confirmed that eltrombopag could provide a rapid, sustained response in patients with poor graft functioning after haematopoietic cell transplantation. This finding is essential given the high rate of non-relapse mortality caused by poor graft functioning after haematopoietic cell transplantation.

Background: Allogeneic hematopoietic stem cell transplantation is a well-established approach for patients diagnosed with primary myelofibrosis and remains the only potentially curative treatment. Aims: To present the overall outcome of patients with myelofibrosis treated with allogeneic hematopoietic stem cell transplantation. Study Design: A retrospective cross-sectional study. Methods: This study is a retrospective analysis of 26 consecutive patients with primary myelofibrosis who underwent transplantation at our center between January 2002 and January 2022. Disease and transplant variables contributing to outcomes were analyzed. Results: The median age at the time of transplantation was 52.5 (range, 32-63) years and the median time from diagnosis to allogeneic hematopoietic stem cell transplantation was 25 (range, 3.1-156.8) months. Myeloablative conditioning and reduced-intensity conditioning regimens were used in 8 (30.8%) and 18 (69.2%) transplantations, respectively. Neutrophil and platelet engraftment was achieved in 23 patients at a median follow-up of 21.2 months (range, 12 days to 234.8 months). Primary graft failure occurred in 1 of 23 patients (4.3%). Neutrophil and platelet engraftment occurred at a median of 16 (range, 12-39) days and 20 (range, 11-78) days, respectively. Acute graft-versus-host disease was seen in 11 of 22 patients engrafted allografts, of which 7 (31.8%) were grade 3-4 acute graft-versus-host disease. Eight patients (36.4%) developed chronic graft-versus-host disease, and three cases were extensive. Four patients (19%) relapsed after a median of 5.5 months, and three patients received donor lymphocyte infusion. The 3-year overall survival rate of the entire study population was 46.2%. The median overall survival was not reached in the myeloablative conditioning group; however, it was 11.9 months in the reduced-intensity conditioning group (p =0.3). According to the donor graft source, the median overall survival was 0.73 months in mismatched unrelated graft recipients, 12 months in matched sibling donors, and not reached in matched unrelated graft recipients (p = 0.03). The 3-year progression-free survival rate of patients who survived > 100 days was 74.7%. The effect of JAK-2 status, graft source, conditioning regimen or dynamic international prognostic scoring system on progression-free survival was not statistically significant. Conclusion: Given the poor prognosis of non-transplant recipients and the lack of non-transplant curative approaches, our results support the consideration of allogeneic hematopoietic stem cell transplantation for eligible patients with primary myelofibrosis.

BACKGROUND: Cusatuzumab, a high-affinity anti-CD70 antibody, has shown preliminary activity as a treatment for acute myeloid leukaemia when combined with azacitidine. We aimed to determine the optimum dose for future trials of cusatuzumab in combination with azacitidine in patients with previously untreated acute myeloid leukaemia who are not eligible for intensive chemotherapy. METHODS: In this randomised, phase 2, open-label, dose-optimisation study we enrolled adult patients aged 18 years or older with newly diagnosed acute myeloid leukaemia not eligible for intensive chemotherapy, and with Eastern Cooperative Oncology Group scores of 0-2, from 40 hospitals and centres across seven countries. In part one of the trial, participants were randomly allocated 1:1 to 10 mg/kg or 20 mg/kg intravenous cusatuzumab on days 3 and 17, combined with subcutaneous or intravenous azacitidine 75 mg/m2 on days 1-7 in 28-day cycles. The primary efficacy outcome was the rate of complete remission in the intention-to-treat group. The two dose cohorts were evaluated independently without between-cohort statistical comparison. Safety analyses were performed in all patients who received one dose of study drug. Part two of the trial was planned to be a single-arm expansion to evaluate cusatuzumab plus azacitidine at the cusatuzumab dose level selected in part one (primary hypothesis ≥35% rate of complete remission vs null hypothesis of 20%); however, changes in the acute myeloid leukaemia treatment landscape during this trial made it unlikely that enrolment to part two of the study would be clinically feasible, so the study stopped at the end of part one. The trial was registered at ClinicalTrials.gov, NCT04023526. FINDINGS: 103 patients were enrolled between Aug 30, 2019, and Feb 25, 2020, and randomly assigned to either cusatuzumab 10 mg/kg (n=51) or 20 mg/kg (n=52). Median follow-up was 7·2 months (IQR 10·7 months). 57 of 103 (55%) patients were male and 46 (45%) patients were female, 78 (76%) were White, one (1%) was Asian, and 24 (23%) did not report their race. In the 10 mg/kg group, complete remission rate was 12% (six of 51 patients; 95% CI 6-23) and in the 20 mg/kg group was 27% (14 of 52; 17-40). Grade 3 or worse treatment-emergent adverse events (TEAEs) were similar between the cusatuzumab 10 mg/kg (n=51) and 20 mg/kg (n=51) cohorts and included thrombocytopenia (24 patients [47%] vs 29 [57%]), anaemia (24 [47%] vs 17 [33%]), and neutropenia (20 [39%] in both cohorts). Serious TEAEs were also similar in the two cohorts (44 [86%] vs 40 [78%]). Treatment-related TEAEs leading to death were reported in both groups (three patients [6%] in the 10 mg/kg group vs one patient [2%] in the 20 mg/kg group); the reported causes of death were pneumonia (n=2) and septic shock (n=2). INTERPRETATION: Although part one of this study was not designed to formally compare the two dose cohorts for efficacy, the totality of clinical data for cusatuzumab studies performed to date indicate that cusatuzumab 20 mg/kg plus azacitidine represents the optimal dose for further studies. A phase 1b study investigating the triple combination of cusatuzumab with venetoclax and azacitidine is underway (NCT04150887). FUNDING: Janssen Research & Development and argenx.
