Abstract

We evaluated the clinical impacts of the concurrent modification of post‐transplant cyclophosphamide (PTCy) dose and tacrolimus (Tac)‐initiation timing in 61 patients with human leukocyte antigen‐haploidentical transplantation. Reduced‐dose PTCy (80 mg/kg) was associated with a higher incidence of moderate‐to‐severe chronic graft‐versus‐host disease (GVHD) than standard‐dose PTCy (100 mg/kg) (35.0% vs. 26.6%, p = 0.053). Notably, early‐initiation Tac (day ‐1) increased moderate‐to‐severe chronic GVHD than standard‐initiation Tac (day 5) in the reduced‐dose PTCy group (p = 0.032), whereas Tac‐initiation timing did not impact chronic GVHD in the standard‐dose PTCy group. These data indicate that the combination of reduced‐dose PTCy and early‐initiation Tac can amplify chronic GVHD.

Although chimeric antigen receptor T-cell (CAR-T) therapies have dramatically improved the outcomes of relapsed/refractory B-cell malignancies, recipients suffer from severe humoral immunodeficiencies. Furthermore, patients with coronavirus disease 2019 (COVID-19) have a poor prognosis, as noted in several case reports of recipients who had COVID-19 before the infusion. We report the case of a 70-year-old woman who developed COVID-19 immediately before CAR-T therapy for high-grade B-cell lymphoma. She received Tixagevimab-Cilgavimab chemotherapy and radiation therapy but never achieved remission. She was transferred to our hospital for CAR-T therapy, but developed COVID-19. Her symptoms were mild and she was treated with long-term molnupiravir. On day 28 post-infection, lymphodepleting chemotherapy was restarted after a negative polymerase chain reaction (PCR) test was confirmed. The patient did not experience recurrence of COVID-19 symptoms or severe cytokine release syndrome. Based on the analysis and comparison of the previous reports with this case, we believe that CAR-T therapy should be postponed until a negative PCR test is confirmed. In addition, Tixagevimab-Cilgavimab and long term direct-acting antiviral agent treatment can be effective prophylaxis for severe COVID-19 and shortening the duration of infection.

BACKGROUND: In patients with relapsed or refractory B cell acute lymphoblastic leukemia or B cell non-Hodgkin lymphoma (r/r B-ALL/B-NHL) with low CD3+ cells in the peripheral blood (PB), sufficient CD3+ cell yield in a single day may not be obtained with normal-volume leukapheresis (NVL). Large-volume leukapheresis (LVL) refers to the processing of more than three times the total blood volume (TBV) in a single session for PB apheresis; however, the efficiency and safety of LVL for manufacturing of tisagenlecleucel (tisa-cel) remain unclear. This study aimed to investigate the tolerability of LVL. STUDY DESIGN AND METHODS: We retrospectively collected data on LVL (≥3-fold TBV) and NVL (<3-fold TBV) performed for patients with r/r B-ALL/B-NHL in our institution during November 2019 and September 2023. All procedures were performed using a continuous mononuclear cell collection (cMNC) protocol with the Spectra Optia. RESULTS: Although pre-apheresis CD3+ cells in the PB were significantly lower in LVL procedures (900 vs. 348/μL, p < .01), all patients could obtain sufficient CD3+ cell yield in a single day with a comparably successful rate of final products (including out-of-specification) between the two groups (97.2% vs. 100.0%, p = 1.00). The incidence and severity of citrate toxicity (no patients with grade ≥ 3) during procedures was not significantly different between the two groups (22.2% vs. 26.1%, p = .43) and no patient discontinued leukapheresis due to any complications. CONCLUSION: LVL procedures using Spectra Optia cMNC protocol was well tolerated and did not affect the manufacturing of tisa-cel.

The Japanese Society of Hematology performed an observational cross-sectional study to clarify the morbidity, prognosis, and prognostic factors in patients with COVID-19 with hematological diseases (HDs) in Japan. The study included patients with HDs who enrolled in our epidemiological survey and had a COVID-19 diagnosis and a verified outcome of up to 2 months. The primary endpoints were characteristics and short-term prognosis of COVID-19 in patients with HDs. A total of 367 patients from 68 institutes were enrolled over 1 year, and the collected data were analyzed. The median follow-up among survivors was 73 days (range, 1-639 days). The 60-day overall survival (OS) rate was 86.6%. In the multivariate analysis, albumin ≤ 3.3 g/dL and a need for oxygen were independently associated with inferior 60-day OS rates (hazard ratio [HR] 4.026, 95% confidence interval (CI) 1.954-8.294 and HR 14.55, 95% CI 3.378-62.64, respectively), whereas 60-day survival was significantly greater in patients with benign rather than malignant disease (HR 0.095, 95% CI 0.012-0.750). Together, these data suggest that intensive treatment may be necessary for patients with COVID-19 with malignant HDs who have low albumin levels and require oxygen at the time of diagnosis.

Relapsed and/or refractory (R/R) primary central nervous system lymphoma (PCNSL) has a poor prognosis. A 57-year-old man diagnosed with PCNSL achieved a complete response by high-dose methotrexate-based chemotherapy followed by autologous hematopoietic stem cell transplantation (ASCT). The disease was not cured, so he was treated with the anti-CD19 chimeric antigen receptor (CAR) T-cell therapy tisagenlecleucel after the third relapse. However, the disease relapsed again 28 days after CAR T-cell therapy. Allogeneic hematopoietic stem cell transplantation (allo-HSCT) was attempted as curative therapy after bridging with second ASCT and tirabrutinib monotherapy. Although a temporary response was achieved, the disease relapsed 98 days after allo-HSCT. While receiving tirabrutinib for relapse after allo-HSCT, the patient developed acute respiratory failure due to transplant-related toxicity and post-transplant thrombotic microangiopathy. He died 175 days after allo-HSCT. Although various treatments for PCNSL have been investigated in recent years, the treatment strategy for R/R PCNSL has not been established. Further studies are warranted to improve the outcomes of patients with R/R PCNSL.

BACKGROUND: Large-volume leukapheresis (LVL) refers to processing of more than three volumes of blood in a single session for peripheral blood stem cell collection. Recently, continuous mononuclear cell collection (cMNC) protocol has been developed using the Spectra Optia system, which is a widely used apheresis device. LVL using the novel protocol has been investigated in patients. However, the efficiency and safety of LVL in healthy donors using this protocol has not been characterized. Therefore, this study aimed to evaluate the efficiency and tolerability of CD34+ collection of LVL with the cMNC protocol in healthy donors. STUDY DESIGN AND METHODS: We retrospectively collected data on LVL (>3 total blood volume) and normal-volume leukapheresis (NVL) performed in healthy donors between October 2019 and December 2021. All procedures were performed using the cMNC protocol. RESULTS: Although pre-apheresis CD34+ cell count was lesser in LVL (23.5 vs. 58.0/μL, p < .001), CD34+ collection efficiency was comparable between LVL and NVL (61.2% vs. 61.4%, p = .966). Platelet loss was significantly higher in LVL compared to NVL (38.0% vs. 29.4%, p < .001), with no correlation between attrition of platelet and processing blood volume. Moreover, the incidence of citrate toxicity during procedures was comparable between the two groups (31.6% vs. 21.4%, p = .322). All LVL procedures could be completed without any adverse events. CONCLUSION: Allogeneic LVL procedure using Spectra Optia cMNC protocol was well tolerated by the donors and resulted in efficient collection of CD34+ cells, which was comparable to that of NVL.

The distribution and clinical impact of cell-of-origin (COO) subtypes of diffuse large B-cell lymphoma (DLBCL) outside Western countries remain unknown. Recent literature also suggests that there is an additional COO subtype associated with the germinal center dark zone, that warrants wider validation to generalize clinical relevance. Here, we assembled a cohort of Japanese patients with untreated DLBCL and determined the refined COO subtypes, that include the dark zone signature (DZsig), using the NanoString DLBCL90 assay. To compare the distribution and clinical characteristics of the molecular subtypes, we used a dataset from the cohort of BC Cancer (BCC) (n = 804). Of the 1050 patients where DLBCL90 assay was successfully performed in our cohort, 35%, 45%, and 6% of patients were identified to be germinal center B-cell-like (GCB)-DLBCL, activated B-cell-like (ABC)-DLBCL, and DZsigpos-DLBCL, respectively, with the highest prevalence of ABC-DLBCL differing significantly from that of BCC (P < 0.001). GCB-DLBCL, ABC-DLBCL, and DZsigpos-DLBCL were associated with two-year overall survival rates of 88%, 75%, and 66%, respectively (P < 0.0001), with patients of the DZsigpos-DLBCL having the poorest prognosis. In contrast, GCB-DLBCL without DZsig showed excellent outcomes following rituximab-containing immunochemotherapy. DZsigpos-DLBCL was associated with the significant enrichment of tumors with CD10 expression, concurrent MYC/BCL2 expression, and depletion of microenvironmental components (all P < 0.05). These results provide evidence of the distinct distribution of clinically relevant molecular subtypes in Japanese DLBCL and that refined COO, as measured by the DLBCL90 assay, is a robust prognostic biomarker that is consistent across geographical areas.

The prognostic impact of corticosteroid therapy in patients receiving tisagenlecleucel (tisa-cel) treatment who are more likely to develop cytokine release syndrome (CRS) remains unclear. This study aimed to evaluate the clinical impact and lymphocyte kinetics of corticosteroid administration for CRS in 45 patients with relapsed and/or refractory B-cell lymphoma treated with tisa-cel. This was a retrospective evaluation of all consecutive patients diagnosed with relapsed and/or refractory diffuse large B-cell lymphoma, follicular lymphoma with histologic transformation to large B-cell lymphoma, or follicular lymphoma who received commercial-based tisa-cel treatment. The best overall response rate, complete response rate, median progression-free survival (PFS), and median overall survival (OS) were 72.7%, 45.5%, 6.6 months, and 15.3 months, respectively. CRS (predominantly grade 1/2) occurred in 40 patients (88.9%), and immune effector cell-associated neurotoxicity syndrome (ICANS) of all grades occurred in 3 patients (6.7%). No grade ≥3 ICANS occurred. Patients with high-dose (≥524 mg, methylprednisolone equivalent; n = 12) or long-term (≥8 days; n = 9) corticosteroid use had inferior PFS and OS to patients with low-dose or no corticosteroid use (both P < .05). The prognostic impact remained even in 23 patients with stable disease (SD) or progressive disease (PD) before tisa-cel infusion (P = .015). but not in patients with better disease status (P = .71). The timing of corticosteroid initiation did not have a prognostic impact. Multivariate analysis identified high-dose corticosteroid use and long-term corticosteroid use as independent prognostic factors for PFS and OS, respectively, after adjusting for elevated lactate dehydrogenase level before lymphodepletion chemotherapy and disease status (SD or PD). Lymphocyte kinetics analysis demonstrated that after methylprednisolone administration, the proportions of regulatory T cells (Tregs), CD4+ central memory T (TCM) cells, and natural killer (NK) cells were decreased, whereas the proportion of CD4+ effector memory T (TEM) cells was increased. Patients with a higher proportion of Tregs at day 7 had a lower incidence of CRS, but this did not affect prognosis, indicating that early elevation of Tregs may serve as a biomarker for CRS development. Furthermore, patients with higher numbers of CD4+ TCM cells and NK cells at various time points had significantly better PFS and OS, whereas the number of CD4+ TEM cells did not impact prognostic outcomes. This study suggests that high-dose or long-term corticosteroid use attenuates the efficacy of tisa-cel, especially in patients with SD or PD. Additionally, patients with high levels of CD4+ TCM cells and NK cells after tisa-cel infusion had longer PFS and OS.

BACKGROUND: Granulocyte transfusion therapy is a rational therapeutic option for patients with prolonged, severe neutropenia. Although high molecular weight hydroxyethyl starch (hHES) facilitates the separation of red blood cells during granulocyte collection, renal dysfunction has been noted as a potential side effect. HES130/0.4 (Voluven®) is a medium molecular weight HES (mHES) with superior safety profiles compared to hHES. Although HES130/0.4 is reportedly effective in the collection of granulocytes, we lack studies comparing the efficiency of granulocyte collection using HES130/0.4 and hHES. STUDY DESIGN AND METHODS: We retrospectively collected the data from 60 consecutive apheresis procedures performed on 40 healthy donors at the Okayama University Hospital between July 2013 and December 2021. All procedures were performed using the Spectra Optia system. Based on the HES130/0.4 concentration in the separation chamber, granulocyte collection methods using HES130/0.4 were classified into m0.46, m0.44, m0.37, and m0.8 groups. We used HES130/0.4 and hHES groups to compare the various sample collection methods. RESULTS: The median granulocyte collection efficiency (CE) was approximately 24.0% and 28.1% in the m0.8 and hHES groups, respectively, which were significantly higher than those in the m0.46, m0.44, and m0.37 groups. One month following granulocyte collection with HES130/0.4, no significant changes were observed in serum creatinine levels compared to those before the donation. CONCLUSION: Therefore, we propose a granulocyte collection approach employing HES130/0.4, which is comparable to the use of hHES in terms of the granulocyte CE. A high concentration of HES130/0.4 in the separation chamber was considered crucial for granulocyte collection.

Mechanisms of prolonged cytopenia (PC) after chimeric antigen receptor (CAR) T-cell therapy, an emerging therapy for relapsed or refractory diffuse large B-cell lymphoma, remain elusive. Haematopoiesis is tightly regulated by the bone marrow (BM) microenvironment, called the 'niche'. To investigate whether alterations in the BM niche cells are associated with PC, we analysed CD271+ stromal cells in BM biopsy specimens and the cytokine profiles of the BM and serum obtained before and on day 28 after CAR T-cell infusion. Imaging analyses of the BM biopsy specimens revealed that CD271+ niche cells were severely impaired after CAR T-cell infusion in patients with PC. Cytokine analyses after CAR T-cell infusion showed that CXC chemokine ligand 12 and stem cell factor, niche factors essential for haematopoietic recovery, were significantly decreased in the BM of patients with PC, suggesting reduced niche cell function. The levels of inflammation-related cytokines on day 28 after CAR T-cell infusion were consistently high in the BM of patients with PC. Thus, we demonstrate for the first time that BM niche disruption and sustained elevation of inflammation-related cytokines in the BM following CAR T-cell infusion are associated with subsequent PC.

The unbalanced translocation der (1;7)(q10;p10) is a characteristic cytogenetic abnormality observed in myelodysplastic syndrome (MDS). A 63-year-old man presented to our hospital with fever and lung disease. The chromosomal analysis of bone marrow cells showed 46, XY, +1, der (1;7)(q10;p10) in all four metaphases. The patient was diagnosed with MDS. Bronchoscope examination revealed organizing pneumonia. The patient's eosinophil count rose to 39% after 30 days. His fever and dyspnea worsened, and a skin rash (systemic erythema) appeared simultaneously. Therefore, the patient was commenced on azacitidine and corticosteroids. Although treatment with both drugs could control disease progression transiently, the WT-1 value and the percentage of myeloblasts in the patient's bone marrow increased. Therefore, the patient received hematopoietic stem cell transplantation from his haplo-identical donor daughter. Some reports have demonstrated that patients with MDS with der (1;7)(q10;p10) have better prognosis than those with other abnormalities, such as -7/7q-. However, reported cases with severe complications show very poor prognosis. MDS with der (1;7)(q10;p10) complicated by eosinophilia and organizing pneumonia have not been reported, and its prognosis is expected to be very poor. Our case suggests that such cases might quickly require hematopoietic stem cell transplantation before the disease worsens.
