RESUMO
The optimal treatment strategy for newly diagnosed primary central nervous system lymphoma (PCNSL) has yet to be established, especially in the elderly. In the current study, we conducted a phase II study to evaluate the efficacy and safety of rituximab plus high-dose MTX followed by rituximab plus cytarabine in patients aged ≥60 years newly diagnosed with PCNSL. Patients received an induction treatment of high-dose methotrexate plus rituximab followed by two cycles of a consolidation treatment of cytarabine plus rituximab. The primary end-point was a 2-year progression-free survival (PFS) rate. A total of 35 patients were recruited, and their median age was 73 (range: 60-81). After induction treatment, the complete and partial responses (PRs) were 56% and 20% respectively. Twenty-six patients proceeded to the consolidation treatment; the complete and PRs were 59% and 9% respectively. After a median follow-up duration of 36.0 months, the 2-year PFS rate was 58.7%. Treatment was generally well-tolerated as only three patients were withdrawn from the study due to toxicity, and no treatment-related mortality was reported. The 2-year overall survival rate was 77.9%. The current study may suggest the feasibility of administering high-dose MTX plus cytarabine in PCNSL patients aged ≥60 years and the potential role of additive rituximab.
RESUMO
Carfilzomib, lenalidomide, and dexamethasone (KRd) combination therapy improves the survival of patients with relapsed and/or refractory multiple myeloma (RRMM). Nonetheless, evidence on the use of KRd in Asian populations remains scarce. Accordingly, this study aimed at investigating this regimen's efficacy in a large group of patients. This retrospective study included patients with RRMM who were treated with KRd at 21 centers between February 2018 and October 2020. Overall, 364 patients were included (median age: 63 years). The overall response rate was 90% in responseevaluable patients, including 69% who achieved a very good partial response or deeper responses. With a median follow-up duration of 34.8 months, the median progression-free survival (PFS) was 23.4 months and overall survival (OS) was 59.5 months. Among adverse factors affecting PFS, highrisk cytogenetics, extramedullary disease, and doubling of monoclonal protein within 2 to 3 months prior to start of KRd treatment significantly decreased PFS and overall survival (OS) in multivariate analyses. Patients who underwent post-KRd stem cell transplantation (i.e.delayed transplant) showed prolonged PFS and OS. Grade 3 or higher adverse events (AEs) were observed in 56% of the patients, and non-fatal or fatal AE's that resulted in discontinuation of KRd were reported in 7% and 2% of patients, respectively. Cardiovascular toxicity was comparable to that reported in the ASPIRE study. In summary, KRd was effective in a large real-world cohort of patients with RRMM with long-term follow-up. These findings may further inform treatment choices in the treatment of patients with RRMM.
RESUMO
The outcomes of patients with myeloma after exposed to penta-classes are extremely poor. Selinexor is the first approved exportin inhibitor for those patients, but intractable toxicities may limit its use. This retrospective study evaluated the real-world efficacy and safety of selinexor plus dexamethasone (XD) and involved 48 patients with multiple myeloma, who were treated from November 2020 to October 2022. Their median age was 64 years, and the median number of prior lines of therapy was 6. The overall response rate was 25%, and the median progression-free survival (PFS) was 2.1 months (95% confidence interval (CI), 1.7-2.5). Patients on a reduced initial dose, delayed treatment, and dose reduction had better PFS. After XD treatment failure, 17 patients received subsequent therapy and had a median PFS of 2.4 months. The median overall survival was 4.6 months (95% CI, 2.3-6.9). Among the patients, 12 (25%) and 17 (35%) experienced dose reduction and delayed treatment, respectively. Our data show that the real-world efficacy of XD treatment in heavily pretreated patients was modest and that improving treatment adherence through reducing initial doses or delaying treatments may improve patient outcomes.

Despite the development of effective agents for multiple myeloma (MM), the management of patients with high-risk MM (HRMM) is challenging. High-dose treatment followed by autologous stem cell transplantation (ASCT) is regarded as upfront treatment for transplant-eligible patients with HRMM. In the present study, we retrospectively investigated the efficacies of two conditioning regimens for upfront ASCT in newly diagnosed patients with MM and high-risk features: high-dose melphalan (HDMEL; 200 mg/m2) and busulfan plus melphalan (BUMEL). In total, 221 patients underwent ASCT between May 2005 and June 2021; among these 221 patients, 79 had high-risk cytogenetic abnormalities. In patients with high-risk cytogenetics, BUMEL showed a tendency toward longer overall survival (OS) and progression-free survival (PFS) compared to HDMEL (median OS; not reached vs. 53.2 months; P = 0.091, median PFS; not reached vs. 31.7 months; P = 0.062). Additionally, multivariate analysis revealed that BUMEL was significantly associated with PFS (hazard ratio = 0.37, 95% confidence interval = 0.15-0.89, P = 0.026). We compared BUMEL with HDMEL in patients with other high-risk features, such as high lactate dehydrogenase level, extramedullary disease, and poor response to frontline therapy. Notably, among patients with less than very good partial response (VGPR) to frontline therapy, median PFS was significantly longer in the BUMEL group than in the HDMEL group (55.1 vs. 17.3 months, respectively; P = 0.011). These findings indicate that BUMEL may be an effective conditioning regimen for upfront ASCT in MM patients with high-risk cytogenetics; BUMEL may be more appropriate than HDMEL for patients with less than VGPR to frontline therapy.

BACKGROUND: As diffuse large B-cell lymphoma (DLBCL) is a very heterogeneous group of lymphomas, much effort has gone in trying to identify patients with increased risk for early death or secondary central nervous system (CNS) involvement. To better predict their outcomes, we measured the levels of various cytokines in serum samples of patients with DLBCL and analyzed their clinical outcomes. METHODS: We measured the levels of seven serum cytokines at diagnosis in 313 DLBCL patients who were treated with R-CHOP. Their impact on clinical outcomes, including time to secondary CNS involvement and the 3-year overall survival (OS) rate, were analyzed. RESULTS: The median age was 56 years (range, 16-86 years), and 177 patients (57%) were men. Secondary CNS involvement was found in 5.4% (16/294) cases, and time to secondary CNS involvement was significantly short in patients with elevated interleukin (IL)-10 (p = 0.012). With the 3-year OS rate of the whole cohort being 73.6%, serum levels of several cytokines, such as CCL3 > 4.0 pg/mL (54.3% vs. 76.1%, p = 0.001), CCL5 > 450 pg/mL (57.0% vs. 78.1%, p < 0.001), any expression of IL-6 (59.3% vs. 76.6%, p = 0.001), and any expression of IL-10 (68.2% vs. 84.5%, p = 0.001), showed prognostic impact. Higher expressions of these cytokines were associated with worse manifestations of clinical prognostic factors. CONCLUSIONS: Our study revealed that some cytokines impact OS and secondary CNS involvement. Future studies are required to elucidate how these findings can be incorporated to the conventional prognostic factors for more tailored approaches.

We assessed the efficacy and toxicity of etoposide, methylprednisolone, high-dose cytarabine, and oxaliplatin (ESHAOx) combination chemotherapy in patients with refractory or relapsed Hodgkin's lymphoma (HL). This was an open-label, non-randomized, multi-center phase II study. The ESHAOx regimen consisted of intravenous (i.v.) etoposide 40 mg/m2 on days 1 to 4, i.v. methylprednisolone 500 mg on days 1 to 5, i.v. cytarabine 2 g/m2 on day 5, and i.v. oxaliplatin 130 mg/m2 on day 1. Cycles (up to six) were repeated every 3 weeks. In an effort to identify prognostic markers, the serum levels of cytokines including tumor necrosis factor-α (TNF-α), C-reactive protein (CRP), and vascular endothelial growth factor (VEGF) were measured at the time of study entry. A total of 37 patients were enrolled, and 36 were available for evaluation of tumor response. The overall response rate was 72.2% (26/36) (complete response, 33.3% [12/36]; partial response, 38.9% [14/36]). The median time to progression was 34.9 months (95% confidence interval, 23.1-46.7 months). The most common grade 3 or 4 hematological adverse events were neutropenia (16/37, 43.2%), followed by thrombocytopenia (10/37, 27.0%). Grade 3 or 4 non-hematological adverse events were nausea (3/37, 8.1%), anorexia (2/37, 5.4%), mucositis (1/37, 2.7%), and skin rash (1/37, 2.7%). There were no treatment-related deaths. High levels of TNF-α and CRP were significantly associated with poorer overall survival (p = 0.00005 for TNF-α, p = 0.0004 for CRP, respectively). The ESHAOx regimen exhibited antitumor activity and an acceptable safety profile in patients with refractory or relapsed HL. Trial Registration: ClinicalTrials.gov.

Although lenalidomide plus dexamethasone (RD) is a therapeutic option for relapsed/refractory multiple myeloma (RRMM), limited real-world clinical data exist. The purpose of this study was to estimate efficacy and safety of RD in RRMM patients of the clinical practice. Data from patients at 25 university hospitals in South Korea between October 2009 and December 2016 were collected retrospectively. We report the effectiveness and safety of RD in 546 RRMM patients in routine clinical practice in South Korea. Patients (median age, 65 years) typically received median 7 cycles of RD, and 184 (33.7%) patients were treated with 10 or more cycles of RD. Patients with renal impairment (CLCr < 40 mL/min; 10.4%), comorbid conditions (≥ 2; 12.0%), and poor performance status (≥ 2; 25.1%) were included. The overall response rate was 64.2%: complete response (13.1%), very good partial response (VGPR 19.9%). With median follow-up duration of 18.6 months, median PFS and OS were 11.2 months and 25.2 months, respectively. In multivariate analysis, less than 2 comorbid conditions, normal LDH, failed one chemotherapy prior to RD, and ≥ 10 cycles of RD therapy had significantly prolonged PFS (P = 0.007, P = 0.011, P = 0.007, and P < 0.001, respectively). Adverse events were acceptable. RD is effective and safe in real-life clinical practice, including patients with comorbidities. RD is an effective and safe treatment in a real clinical setting which includes patients with comorbidities. Early and continual use of RD treatment may improve RRMM survival outcomes.

To better predict the outcomes of patients with peripheral T-cell lymphoma (PTCL), we measured the levels of various cytokines in serum samples from patients with PTCL and analyzed their clinical outcomes. We measured 34 cytokines in samples from 121 PTCL patients (55 PTCL-not otherwise specified (NOS), 44 angioimmunoblastic T-cell lymphoma (AITL), and 22 ALK- anaplastic large cell lymphoma) at diagnosis. Their impact on clinical outcomes, including overall survival and complete response rate, were analyzed with other clinical variables. The median age of patients was 58â¯years (range, 20-85â¯years) and 81 patients (66.9%) were male. The median overall survival among all patients was 56.1â¯months (95% CI 21.4-90.8) and median progression-free survival was 19.3â¯months (95% CI 12.3-26.3). Patients with AITL were more likely to express higher levels of serum cytokines, and 7 cytokines showed mean levels that were significantly higher than those in other subtypes. In this subgroup, IL-10 higher than 3.8â¯pg/mL was associated with adverse outcomes. In patients with ALK- anaplastic large cell lymphoma, 9 cytokines showed a prognostic impact, with higher levels of interferon γ, interleukin (IL)-8, IL-10, IL-17, IL-23, IP-10, monocyte chemoattractant protein-1, macrophage inflammatory protein-1ß, and RANTES negatively affecting clinical outcomes. In PTCL-NOS, patients with elevated levels of interferon γ, IL-7, and IL-23 showed poor outcomes. The current analysis demonstrated different cytokine profiles according to histologic subtype, which revealed the heterogeneity of PTCL. In addition, cytokine levels can be used as prognostic markers and may be useful for therapeutic applications in PTCL patients.

BACKGROUND: The upregulated expression of the JAK/STAT pathway promotes tumor growth in Hodgkin lymphoma (HL) and primary mediastinal large B-cell lymphoma (PMBCL). Based on the hypothesis that JAK2 is a therapeutic target, we performed a prospective pilot study using ruxolitinib. METHODS: Relapsed or refractory patients with HL or PMBCL were eligible for this study, and JAK2 amplification was assessed by fluorescence in situ hybridization. Ruxolitinib was administered orally at a dose of 20 mg twice daily for a 28-day cycle. Treatment was continued for up to 16 cycles or until progressive disease or intolerability. The primary objective was to assess the overall disease control rate comprising complete response (CR), partial response (PR), or stable disease (SD). RESULTS: We analyzed 13 HL patients and six PMBCL patients. All responders (one CR, five PR, and one SD) had HL whereas all cases of PMBCL progressed after first or second cycle. The disease control rate for HL was 54% (7/13) with median response duration of 5.6 months. JAK2 amplification was present in six of nine patients tested (four HL, two PMBCL), and three of these HL patients showed PR (n = 2) or SD (n = 1). None of the three HL patients shown to not have JAK2 amplification responded to ruxolitinib. Most treatment-related adverse events were grade 1 or 2 and manageable. CONCLUSIONS: Ruxolitinib has single-agent activity against HL but does not act against PMBCL with or without JAK2 amplification. TRIAL REGISTRATION: The study population was patients who had relapsed or refractory HL or PMBCL, and patients were registered for our pilot study after providing written informed consent between November 2013 and November 2015 (CilinicalTrials.gov: NCT01965119).

Monomorphic epitheliotropic intestinal T-cell lymphoma (MEITL) is a provisional entity in the 2017 World Health Organization classifications. To further elucidate the clinicopathologic features of this new disease, we carried out a retrospective, multicenter analysis of 42 patients with MEITL. The median age of the patients was 59 years (range, 20-84 years), and 27 patients (64 %) were male. Thirty-two patients (76 %) were Ann-Arbor stages I-II and 28 (67 %) were Lugano stages I-II1&2. The most frequent site of involvement was the jejunum (N = 21). Most cases expressed CD8 (79 %) and CD56 (95 %) and did not express CD30 (5 %) or EBER (0 %). The median progression-free survival was 6.9 months (95 % CI 4.3-9.6); the median OS was 14.8 months (2.4-27.2). Thirty-two patients (76 %) underwent surgery and 37 (88 %) received chemotherapy. A complete response (CR) rate was 38 %. Sixteen patients had undergone autologous stem cell transplantation (ASCT). Relapse or progression was documented in 24 cases, most frequently in the primary site (N = 23). Four cases showed central nervous system relapse. Age over 55 years, poor performance scale, advanced Lugano stage (IIE-IV), not achieving CR, and not receiving ASCT were associated with inferior OS. While the optimal management of MEITL remains undetermined, achieving CR and consolidative ASCT seem essential. As CHOP might be insufficient for achieving CR, more efficient combinations should be investigated. Additionally, considering the frequent local failure and CNS relapse, novel therapeutic approaches are required to improve survival.

Arsenic compounds have been used in traditional medicine for several centuries. KML001 (sodium metaarsenite; NaAsO2) is an orally bio-available arsenic compound with potential anti-cancer activity. However, the effect of KML001 has not been studied in lymphoid neoplasms. The aim of this study is to evaluate the anti-proliferative effect of KML001 in non-Hodgkin's lymphoma and to compare its efficacy with As2O3. KML001 inhibited cellular proliferation in all tested lymphoma cell lines as well as JurkatR cells (adriamycin-resistant Jurkat cells) in a dose-dependent manner, while As2O3 was not effective. Cell cycle regulatory protein studies have suggested that KML001 induces G1 arrest via p27-induced inhibition of the kinase activities of CDK2, 4, and 6. Treatment of KML001 induced apoptosis in Jurkat and JurkatR cells. The apoptotic process was associated with down-regulation of Bcl-2 (antiapoptotic molecule), up-regulation of Bax (proapoptotic molecule), and inhibition of caspase-3, -8, and -9. In addition, cell signaling including the STAT, PI3K/Akt, MAPK, and NF-κB signal pathways were inhibited in KML001-treated Jurkat and JurkatR cells. Furthermore, targeting the telomere by KML001 was observed in the Jurkat and JurkatR cells. The In vivo anti-tumoral activity of KML001 was confirmed in a xenograft murine model. Interestingly, partial responses were seen in two lymphoma patients treated with 10 mg/day (follicular lymphoma for 16 weeks and mantle cell lymphoma for 24 weeks) without severe toxicities. These findings suggest that KML001 may be a candidate agent for the treatment of de novo, refractory, and relapsed non-Hodgkin's lymphoma patients.

Purpose: Given that 40~50% of primary central nervous system lymphoma (PCNSL) tissues exhibit aberrancy on 9p24.1, immune-checkpoint inhibitors (ICI) may work for the disease. Materials and Methods: To define the role of ICIs in PCNSL, we carried out a nationwide retrospect analysis for 22 patients who had been treated with nivolumab monotherapy for relapsed or refractory PCNSL. Results: The median age at diagnosis was 66, and male: female ratio was 1:1. Patients received nivolumab after a median of 3 lines (range, 2 - 6) of therapy and at the median age of 67 (range, 37 - 82). Eleven patients (50%) were refractory to the last treatment prior to nivolumab. With a median follow-up duration of 22.3 months (95% CI, 13.1 - 31.5), nine patients (41%) had an objective response (6 complete responses, 3 partial responses), and the median duration of response was 20.9 months (95% CI, 1.7 - 40.0). The median progression-free survival and overall survival were 2.1 months (95% CI, 0.2 - 4.0) and 18.9 months (95% CI, 5.0 - 32.8), respectively. Nivolumab was generally well-tolerated as no patients required dose reduction and only 2 patients required delay of treatment. Conclusion: Our study suggests that nivolumab can be a reasonable option with the durable response for RR PCNSL.
RESUMO
PURPOSE: Programmed death-1 blockade with pembrolizumab has shown promising activity in relapsed/refractory (R/R) extranodal natural killer/T-cell lymphoma (NKTCL), but studies are limited, with small patient numbers. MATERIALS AND METHODS: Thirteen institutes involved with the Consortium for Improving Survival of Lymphoma, a Korean lymphoma study group, collected the clinical data of 59 patients treated with pembrolizumab as salvage therapy between 2016 and 2022. RESULTS: The median age of the patients was 60 years (range, 22 to 87 years), and 76.3% had advanced Ann Abor stage disease. Pembrolizumab was given to 35.6%, 40.7%, and 23.7% of the patients as second-, third-, and fourth- or higher-line chemotherapy, respectively. The overall response rate was 40.7%, with 28.8% having complete response. The estimated 2-year progression-free survival (PFS) and overall survival rates for all patients were 21.5% and 28.7%, respectively; for responders, the rates were 53.0% and 60.7%, respectively. Although not statistically significant, Eastern Cooperative Oncology Group performance status ≥ 2 (hazard ratio [HR], 1.91; 95% confidence interval [95% CI], 0.93 to 3.94; p=0.078) and stage III or IV disease (HR, 2.59; 95% CI, 0.96 to 6.96; p=0.060) were associated with a trend toward shorter PFS in multivariate analysis. Grade 3 or 4 adverse events (AEs) were noted in 12 patients (20.3%); neutropenia (10.2%), fatigue (6.8%), and pneumonitis (5.1%) were most common AEs. CONCLUSION: In conclusion, while pembrolizumab had a modest effect on patients with R/R NKTCL, it may be a useful salvage therapy for patients with localized disease and good performance status.

BACKGROUND: Hepatitis B virus reactivation (HBVr) is a well-known complication of systemic chemotherapy for particularly hematologic malignancies in HBV carriers. We performed a multicenter retrospective study to investigate the incidence and risk factors of HBVr in patients with hepatitis B surface antigen (HBsAg)-positive multiple myeloma (MM). METHODS: We included 123 patients with HBsAg-positive MM who had received systemic therapy. The primary objective of the study was to evaluate the incidence of HBVr in patients with HBsAg-positive MM. RESULTS: The median age was 59 years, and 72 patients were male. With a median follow-up duration of 41.4 months, there were 43 instances of HBVr in 35 patients (28.5%): 29 treatment-related HBVr occurred during 424 treatments. Treatments containing antiviral prophylaxis were associated with a significantly lower incidence of HBVr compared to those without (14.4% vs. 1.9%, P < 0.001). Moreover, treatment with cyclophosphamide (P = 0.002) and doxorubicin (P = 0.053) were risk factors for HBVr; stem cell transplantation was not associated with HBVr. There was no significant difference in overall survival between patients with and without HBVr (P = 0.753) and myeloma progression was the major cause of death. CONCLUSION: Considering the low incidence of HBVr in patients who had received antiviral prophylaxis, HBsAg-positivity should not impede patients from receiving optimal antimyeloma treatment or participating in clinical trials.

Potential synergism between Bruton's tyrosine kinase (BTK) inhibitor and lenalidomide in treating aggressive B-cell lymphoma has been suggested. Here, the authors report a single-arm phase II clinical trial of combination of acalabrutinib, lenalidomide and rituximab (R2A) in patients with aggressive relapsed/refractory aggressive (R/R) B-cell non-Hodgkin lymphoma (NHL). The primary endpoint of this study is objective response rate (ORR), and the secondary endpoints are complete remission (CR) rate, duration of response (DoR), progression-free survival (PFS) and overall survival (OS). A total of 66 patients are enrolled mostly with diffuse large B-cell lymphoma. The ORR is 54.5% and CR rate is 31.8% meeting the primary end point. The median DoR is 12.9 months, and 1-year PFS and OS rate is 33.1% and 67.5% respectively. Adverse events (AE) are manageable with the most frequent AE being neutropenia (31.8%). Patients with MYD88 mutations, subtypes known for NF-κB activation, and high BTK expression by immunohistochemistry respond well. Overall, these results show a significant efficacy of the R2A regimen in patients with aggressive R/R B-cell NHL, with exploratory biomarkers suggesting potential associations with response.

BACKGROUND: Converting chemotherapy followed by surgery is known to be associated with improved clinical outcomes in colorectal cancer (CRC) patients with hepatic metastasis. This study is to investigate the clinicopathological prognostic factors for disease-free survival (DFS) after curative resection of primary and metastatic lesions. METHODS: We retrospectively analyzed the medical records of 76 CRC patients who had initially had unresectable hepatic metastasis, which was considered resectable after systemic chemotherapy, and had undergone curative surgery in the period from January 2006 to December 2011. DFS was compared by assessing clinical data including age, sex, staging, number of hepatic lesion(s), size of the largest hepatic lesion and serum carcinoembryonic antigen (CEA) levels. RESULTS: The median age was 57 years and 47 patients were male. The median DFS was 10.4 months. Multivariate Cox regression analysis revealed that age <50 years (HR 2.70, 95% CI 1.43-5.10, p = 0.002) and CEA elevation after curative surgery (HR 2.20, 95% CI 1.11-4.36, p = 0.023) were associated with a shorter DFS. CONCLUSIONS: Given that patients <50 years old or with elevated CEA levels after curative surgery demonstrated a short DFS, additional postoperative systemic treatment or active surveillance, at least, should strongly be considered for this group.

Decitabine is a hypomethylating agent with proven clinical efficacy in myelodysplastic syndrome (MDS). The current study analyzed the role of single nucleotide polymorphism array (SNP-A)-based karyotyping in prediction of clinical outcome in MDS or chronic myelomonocytic leukemia (CMML) patients following decitabine therapy. A total of 61 MDS/CMML patients treated with decitabine were evaluated with Genome-Wide Human SNP 6.0 Array using DNAs derived from marrow samples. The primary endpoint was the best response rate including complete (CR) and partial response (PR) with overall (OS) and event-free survival (EFS) as secondary endpoints. Best response was noted in 14 patients (26.4 %) out of 53 evaluated patients including 12 CR and two PR with median follow-up of 21.6 months. A total of 81 abnormal SNP lesions were found in 25 out of 61 patients (41.0 %). The patients carrying abnormal SNP lesions showed an inferior CR/PR rate (p = 0.002) and showed a trend of worse OS (p = 0.02 in univariate, p = 0.09 in multivariate) compared to those without SNP lesions, but not were associated with inferior EFS. The presence of abnormal SNP lesions in MDS was associated with adverse outcomes following decitabine therapy. Further study is strongly warranted to establish the role of SNP-A karyotyping in MDS.

The gastrointestinal stromal tumor is the most common mesenchymal neoplasm of the gastrointestinal tract. The gastrointestinal stromal tumor universally expresses KIT and DOG-1 and frequently harbors oncogenic mutations in the KIT gene. While the gastrointestinal stromal tumor usually arises in the alimentary tract, it is rarely found in the extragastrointestinal area. When it is, it is called an extragastrointestinal stromal tumor. Although the pathogenesis, prognostic factors and outcomes of gastrointestinal stromal tumors are well known, those of extragastrointestinal stromal tumors have not been fully studied. We report, herein, a unique primary extragastrointestinal stromal tumor from the pleura in a 73-year-old woman who presented with pleural mass. The extragastrointestinal stromal tumor was surgically resected and confirmed by means of an immunohistochemical study and a molecular analysis.

Background: Brentuximab vedotin (BV), a potent antibody-drug conjugate, targets the CD30 antigen. In Korea, BV has been approved for the treatment of relapsed or refractory Hodgkin lymphoma (HL), anaplastic large-cell lymphoma (ALCL), and cutaneous T-cell lymphomas, including mycosis fungoides (MF). However, there are limited data reflecting real-world experiences with BV treatment for HL, ALCL, and MF. Methods: This was a multicenter, non-interventional registry study of the efficacy and safety of BV in patients with relapsed or refractory CD30-positive lymphoma (CISL1803/BRAVO). Outcomes were determined based on the occurrence of relapse or progression and overall survival after BV treatment. Results: A total of 85 patients were enrolled in this study. The median number of BV cycles was 10 (range, 2â16) in the patients with HL. The objective response rate (ORR) of patients with HL to BV was 85.4% (41/48), comprising 27 complete responses (CRs) and 14 partial responses (PRs). The ORR of ALCL was 88% (22/25), consisting of 17 CRs and five PRs, whereas the ORR of MF was 92% (11/12). At the median follow-up of 44.6 months after BV treatment, the median post-BV progression-free survival of HL, ALCL, and MF patients was 23.6 months, 29.0 months, and 16.7 months, respectively (P=0.641). The most common side effect of BV was peripheral neuropathy; 22 patients (25.9%, 22/85) experienced peripheral neuropathy (all grades). Conclusion: The treatment outcomes of patients with relapsed or refractory CD30-positive lymphoma improved with BV treatment, and the safety profile was manageable.
RESUMO
BACKGROUND: CT-P10 was the first licensed rituximab biosimilar. This Korean post-marketing surveillance study evaluated CT-P10 safety and effectiveness in approved indications. RESEARCH DESIGN AND METHODS: This prospective, open-label, observational, phase 4 study collected routine clinical practice data across 27 centers in the Republic of Korea. Patients received their first CT-P10 treatment, per prescribing information, for non-Hodgkin's lymphoma (NHL), chronic lymphocytic leukemia (CLL), rheumatoid arthritis (RA), granulomatosis with polyangiitis (GPA), or microscopic polyangiitis (MPA) during the surveillance period (16 November 2016-15 November 2020). Safety (including adverse events [AEs] and adverse drug reactions [ADRs]) and disease-specific clinical response (by best overall response [NHL/CLL], Disease Activity Score in 28-joints [RA], or Birmingham Vasculitis Activity Score for Wegener's Granulomatosis [GPA/MPA]) were assessed for ≤1 year (NHL/CLL) or ≤24 weeks (RA/GPA/MPA). RESULTS: The safety population comprised 677 patients (604 NHL, 16 CLL, 42 RA, 7 GPA, 8 MPA). AEs/ADRs were reported for 68.4%/27.7% (NHL/CLL), 31.0%/14.3% (RA), and 86.7%/13.3% (GPA/MPA) of patients. Serious AEs and unexpected ADRs did not raise new safety signals. Pneumonia was the most frequent serious ADR overall. Positive effectiveness outcomes were observed. CONCLUSIONS: Findings were consistent with the known CT-P10/reference rituximab safety profile, with high effectiveness observed in NHL/CLL and RA.
