Assessing the efficacy and tolerability of PET-guided BrECADD versus eBEACOPP in advanced-stage, classical Hodgkin lymphoma (HD21): a randomised, multicentre, parallel, open-label, phase 3 trial.

Background: Intensified systemic chemotherapy has the highest primary cure rate for advanced-stage, classical Hodgkin lymphoma but this comes with a cost of severe and potentially life long, persisting toxicities. With the new regimen of brentuximab vedotin, etoposide, cyclophosphamide, doxorubicin, dacarbazine, and dexamethasone (BrECADD), we aimed to improve the risk-to-benefit ratio of treatment of advanced-stage, classical Hodgkin lymphoma guided by PET after two cycles.

Methods: This randomised, multicentre, parallel, open-label, phase 3 trial was done in 233 trial sites across nine countries.

Management of Patients Undergoing CAR-T Cell Therapy in Germany.

Introduction: Chimeric antigen receptor positive T cell (CAR-T cell) treatment became standard therapy for relapsed or refractory hematologic malignancies, such as non-Hodgkin's lymphoma and multiple myeloma. Owing to the rapidly progressing field of CAR-T cell therapy and the lack of generally accepted treatment guidelines, we hypothesized significant differences between centers in the prevention, diagnosis, and management of short- and long-term complications.

Methods: To capture the current CAR-T cell management among German centers to determine the medical need and specific areas for future clinical research, the DAG-HSZT (Deutsche Arbeitsgemeinschaft für Hämatopoetische Stammzelltransplantation und Zelluläre Therapie; German Working Group for Hematopoietic Stem Cell Transplantation and Cellular Therapy) performed a survey among 26 German CAR-T cell centers.

Inotuzumab Ozogamicin as Induction Therapy for Patients Older Than 55 Years With Philadelphia Chromosome-Negative B-Precursor ALL.

Purpose: Despite recent advances in adapting the intensity of treatment for older patients with ALL, current protocols are associated with high rates of early deaths, treatment-related toxicity, and dismal prognosis. We evaluated inotuzumab ozogamicin and dexamethasone (Dex) as induction therapy in older patients with ALL within the German Multicenter Study Group for Adult ALL (GMALL).

Patients And Methods: The open-label, multicenter, phase II, INITIAL-1 trial enrolled 45 patients older than 55 years with newly diagnosed, CD22-positive, -negative B-precursor ALL (B-ALL).

AFM13 in patients with relapsed or refractory classical Hodgkin lymphoma: final results of an open-label, randomized, multicenter phase II trial.

In patients with relapse of classical Hodgkin lymphoma (cHL) after autologous stem cell transplant, brentuximab vedotin and anti-PD1 treatment, the outcome is poor. To assess the efficacy of the bispecific anti-CD30/CD16A, NK-cell engaging antibody AFM13 and to select the optimal treatment schedule (arm A-C), we initiated a randomized two-stage phase II trial (NCT02321592). Due to slow recruitment, the trial was terminated after treatment of 25 patients.

Longitudinal Outcome over Two Decades of Unrelated Allogeneic Stem Cell Transplantation for Relapsed/Refractory Acute Myeloid Leukemia: An ALWP/EBMT Analysis.

Purpose: We evaluated outcomes of unrelated transplantation for primary refractory/relapsed (ref/rel) acute myeloid leukemia (AML), comparing two cohorts according to the year of transplant, 2000-2009 and 2010-2019.

Patients And Methods: Multivariable analyses were performed using the Cox proportional-hazards regression model.

Results: 3,430 patients were included; 876 underwent a transplant between 2000-2009 and 2554 in 2010-2019.

Prognostic value of a new clinically-based classification system in patients with CMML undergoing allogeneic HCT: a retrospective analysis of the EBMT-CMWP.

Recently a new three-group clinical classification was reported by an International Consortium to stratify CMML patients with regard to prognosis. The groups were defined as follows: (1) Myelodysplastic (MD)-CMML: WBC ≤ 10 × 10/l, circulating immature myeloid cells (IMC) = 0, no splenomegaly; (2) MD/MP (overlap)-CMML: WBC 10-20 × 10/l or WBC ≤ 10 × 10/l but IMC > 0 and/or splenomegaly; (3) Myeloproliferative (MP)-CMML: WBC > 20 × 10/l. By analysing EBMT Registry patients who underwent allo-HCT for CMML between 1997 and 2016, we aimed to determine the impact of this classification on transplantation outcome and to make a comparison with the conventional WHO classification (CMML-0/CMML-1/CMML-2).

Impact of the first COVID-19 lockdown in Germany on the rate of acute infections during intensive chemotherapy for Hodgkin lymphoma.

Purpose: Evidence on the effect of self-protection via social distancing and wearing face-masks on infections during chemotherapy is currently not available. We asked if the occurrence of acute infections during chemotherapy for advanced-stage Hodgkin lymphoma (HL) decreased when COVID-19 protection measures were in effect.

Methods: We analyzed the occurrence of infections during all documented eBEACOPP cycles starting between 01 March and 30 June of 2017 to 2020 in patients treated within the GHSG HD21 study in Germany and compared the infection rates and characteristics by logistic regression models and means of descriptive statistics.

PET-guided omission of radiotherapy in early-stage unfavourable Hodgkin lymphoma (GHSG HD17): a multicentre, open-label, randomised, phase 3 trial.

Background: Combined-modality treatment consisting of chemotherapy and consolidation radiotherapy is standard of care for patients with early-stage unfavourable Hodgkin lymphoma. However, the use of radiotherapy can have long-term sequelae, which is of particular concern, as Hodgkin lymphoma is frequently diagnosed in young adults with a median age of approximately 30 years. In the German Hodgkin Study Group HD17 trial, we investigated whether radiotherapy can be omitted without loss of efficacy in patients who have a complete metabolic response after receiving two cycles of escalated doses of etoposide, cyclophosphamide, and doxorubicin, and regular doses of bleomycin, vincristine, procarbazine, and prednisone (eBEACOPP) plus two cycles of doxorubicin, bleomycin, vinblastine, dacarbazine (ABVD) chemotherapy (2 + 2).

Alternative donors provide comparable results to matched unrelated donors in patients with acute lymphoblastic leukemia undergoing allogeneic stem cell transplantation in second complete remission: a report from the EBMT Acute Leukemia Working Party.

Relapse of acute lymphoblastic leukemia (ALL) remains a major therapeutic challenge. Despite the consensus for proceeding to allogeneic stem cell transplantation (HSCT) in relapsing patients with ALL who achieve second complete remission (CR2) with salvage therapy, most patients lack a suitable matched-related histocompatible donor. The present multicenter retrospective study compared, for ALL patients in CR2, the HSCT outcome from all four possible alternative hematopoietic stem cell sources, namely matched unrelated 10/10 (n = 281), mismatched unrelated 9/10 (n = 125), haploidentical (n = 105), and cord blood (n = 104) donors.

Outcome of allogeneic haematopoietic stem cell transplantation in myeloproliferative neoplasm, unclassifiable: a retrospective study by the Chronic Malignancies Working Party of the EBMT.

Myeloproliferative Neoplasm (MPN), unclassifiable (MPN-U) is a heterogeneous disease with regards to both clinical phenotype and disease course. Patients may initially be asymptomatic or present with leucocytosis or thrombocytosis, anaemia, progressive splenomegaly, constitutional symptom, thromboses or accelerated/blastic phase disease. Treatment strategies are variable and there are no widely accepted consensus management guidelines for MNU-U.

Asparaginase activities during intensified treatment with pegylated asparaginase in adults with newly-diagnosed acute lymphoblastic leukemia.

The GMALL07/2003 protocol introduced pegylated asparaginase (PEG-ASNase) frontline for adults with acute lymphoblastic leukemia (ALL). PEG-ASNase (500 U/m, 1000 U/m, or 2000 U/m) was given once in induction and as part of three HD-MTX/PEG-ASNase cycles with two PEG-ASNase doses every other week in consolidation. PEG-ASNase activities were monitored in 1363 serum samples from 304 ALL patients.

Mutations in ACTL6B Cause Neurodevelopmental Deficits and Epilepsy and Lead to Loss of Dendrites in Human Neurons.

We identified individuals with variations in ACTL6B, a component of the chromatin remodeling machinery including the BAF complex. Ten individuals harbored bi-allelic mutations and presented with global developmental delay, epileptic encephalopathy, and spasticity, and ten individuals with de novo heterozygous mutations displayed intellectual disability, ambulation deficits, severe language impairment, hypotonia, Rett-like stereotypies, and minor facial dysmorphisms (wide mouth, diastema, bulbous nose). Nine of these ten unrelated individuals had the identical de novo c.

De Novo Variants in GRIA4 Lead to Intellectual Disability with or without Seizures and Gait Abnormalities.

Using trio whole-exome sequencing, we have identified de novo heterozygous pathogenic variants in GRIA4 in five unrelated individuals with intellectual disability and other symptoms. GRIA4 encodes an AMPA receptor subunit known as GluR4, which is found on excitatory glutamatergic synapses and is important for learning and memory. Four of the variants are located in the highly conserved SYTANLAAF motif in the transmembrane protein M3, and the fifth is in an extra-cellular domain.

Two cycles of risk-adapted consolidation therapy in patients with acute promyelocytic leukemia. Results from the SAL-AIDA2000 trial.

The combination of all-trans retinoic acid (ATRA) and idarubicin (AIDA) for induction therapy followed by three cycles of risk-adapted consolidation cycles is considered standard of care for patients with acute promyelocytic leukemia (APL). We report the outcome of 141 patients (median age 51 years; range, 19-82, 31 % ≥60 years) enrolled into the prospective Study Alliance Leukemia (SAL)-AIDA2000 trial, which comprised AIDA-based induction followed by only two courses of risk-adapted consolidation (daunorubicin or mitoxantrone ± cytarabine) followed by 2-year maintenance treatment. The early death rate was 7 % (median age 66 years), and additional 9 % stopped further treatment after induction.

Sex and body mass index but not CXCL12 801 G/A polymorphism determine the efficacy of hematopoietic cell mobilization: a study in healthy volunteer donors.

Analyses of healthy donors of granulocyte colony-stimulating factor (G-CSF) mobilized hematopoietic stem and progenitor cells (HSPCs) and of patients undergoing autologous stem cell transplantation have suggested that individuals harboring the CXCL12-A allele mobilize a higher number of CD34 + HSPCs after G-CSF administration. We typed 463 healthy unrelated donors (376 men and 87 women) who had received daily subcutaneous injections at a mean dose of 7.36 ± 1.

Addition of AEG35156 XIAP antisense oligonucleotide in reinduction chemotherapy does not improve remission rates in patients with primary refractory acute myeloid leukemia in a randomized phase II study.

Background: XIAP (X-linked inhibitor of apoptosis protein) is an inhibitor of caspases 3 and 9 that is overexpressed in acute myeloid leukemia (AML) and may contribute to chemoresistance. We report an open-label randomized phase II trial of reinduction chemotherapy with and without the XIAP antisense oligonucleotide AEG35156 in patients with AML who did not achieve remission with initial induction chemotherapy.

Methods: Twenty-seven patients with AML who were refractory to initial induction chemotherapy were randomized and treated with AEG35156 (650 mg) in combination with high-dose cytarabine and idarubicin.

Emotional context during encoding of neutral items modulates brain activation not only during encoding but also during recognition.

In general, encoding of neutral material includes the context in which the respective material is learned. The effect of emotional context on successfully encoded neutral material has been investigated only recently in few studies, but the main underlying mechanisms are still fairly unknown. In the present study, we investigated the effect of positive and negative emotional context on encoding and later recognition of neutral items.

Immunochemotherapy with rituximab and cyclophosphamide, doxorubicin, vincristine, and prednisone significantly improves response and time to treatment failure, but not long-term outcome in patients with previously untreated mantle cell lymphoma: results of a prospective randomized trial of the German Low Grade Lymphoma Study Group (GLSG).

Purpose: Mantle cell lymphoma (MCL) is characterized by a poor prognosis with a low to moderate sensitivity to chemotherapy and a median survival of only 3 to 4 years. In an attempt to improve outcome, the German Low Grade Lymphoma Study Group (GLSG) initiated a randomized trial comparing the combination of cyclophosphamide, doxorubicin, vincristine, and prednisone (CHOP) and rituximab (R-CHOP) with CHOP alone as first-line therapy for advanced-stage MCL.

Patients And Methods: One hundred twenty-two previously untreated patients with advanced-stage MCL were randomly assigned to six cycles of CHOP (n = 60) or R-CHOP (n = 62).
