To reduce axi-cel-related toxicity, several exploratory safety management cohorts were added to ZUMA-1 (NCT02348216), the pivotal phase 1/2 study of axi-cel in refractory LBCL. Cohort 4 evaluated the rates and severity of cytokine release syndrome (CRS) and neurologic events (NEs) with earlier corticosteroid and tocilizumab use. Primary endpoints were incidence and severity of CRS and NEs. Patients received 2 × 106 anti-CD19 CAR T cells/kg after conditioning chemotherapy. Forty-one patients received axi-cel. Incidences of any-grade CRS and NEs were 93\% and 61\%, respectively (grade ≥ 3, 2\% and 17\%). There was no grade 4 or 5 CRS or NE. Despite earlier dosing, the cumulative cortisone-equivalent corticosteroid dose in patients requiring corticosteroid therapy was lower than that reported in the pivotal ZUMA-1 cohorts. With a median follow-up of 14·8 months, objective and complete response rates were 73\% and 51\%, respectively, and 51\% of treated patients were in ongoing response. Earlier and measured use of corticosteroids and/or tocilizumab has the potential to reduce the incidence of grade ≥ 3 CRS and NEs in patients with R/R LBCL receiving axi-cel.}, language = {en} } @article{SteinhardtKrummenastRosenwaldetal.2022, author = {Steinhardt, Maximilian J. and Krummenast, Franziska C. and Rosenwald, Andreas and Gerhard-Hartmann, Elena and Heidemeier, Anke and Einsele, Hermann and Topp, Max S. and Duell, Johannes}, title = {R-CHOP intensification with mid-cycle methotrexate and consolidating AraC/TT with BCNU/aHSCT in primary aggressive lymphoma with CNS involvement}, series = {Journal of Cancer Research and Clinical Oncology}, volume = {148}, journal = {Journal of Cancer Research and Clinical Oncology}, number = {1}, issn = {1432-1335}, doi = {10.1007/s00432-021-03663-x}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-267731}, pages = {205-214}, year = {2022}, abstract = {Purpose Patients suffering from aggressive systemic peripheral lymphoma with primary central nervous system involvement (PCL) are a rare and sparsely investigated population. Recommended treatment regimens include a combination of intrathecal and systemic chemotherapy as well as whole brain radiotherapy while offering relatively poor survival. Methods We conducted a single-center retrospective study that analyzed safety and outcome of 4 + 4 cycles Rituximab (R)-CHOP and R-high-dose Methotrexate (HD-MTX) for newly diagnosed, transplant-eligible patients ("Ping-Pong"), followed by Cytarabine (AraC)/Thiotepa (TT), BCNU/TT, and autologous hematologic stem cell transplantation (aHSCT). We retrospectively analyzed a set of 16 patients with high-intermediate or high-risk IPI status. Results Overall response rate to Ping-Pong was 100\% measured by CT/MRI, including 93.75\% complete remissions after BCNU/TT followed by PBSCT. One patient failed to qualify for high-dose chemotherapy due to progression when receiving Cytarabine/TT. All patients experienced grade III adverse events, 3 of them a grade IV adverse event. Estimated progression-free survival is 93.75\% after a 4.8-year follow-up currently. Conclusion Our study suggests high effectivity of R-CHOP with mid-cycle MTX with aHSCT consolidation towards acceptable OS results in this challenging patient population.}, language = {en} } @article{RascheDuellMorgneretal.2013, author = {Rasche, Leo and Duell, Johannes and Morgner, Charlotte and Chatterjee, Manik and Hensel, Frank and Rosenwald, Andreas and Einsele, Hermann and Topp, Max S. and Br{\"a}ndlein, Stephanie}, title = {The Natural Human IgM Antibody PAT-SM6 Induces Apoptosis in Primary Human Multiple Myeloma Cells by Targeting Heat Shock Protein GRP78}, series = {PLoS ONE}, volume = {8}, journal = {PLoS ONE}, number = {5}, doi = {10.1371/journal.pone.0063414}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-130125}, pages = {e63414}, year = {2013}, abstract = {In contrast to other haematological malignancies, targeted immunotherapy has not entered standard treatment regimens for de novo or relapsed multiple myeloma (MM) yet. While a number of IgG-formatted monoclonal antibodies are currently being evaluated in clinical trials in MM, our study aimed to investigate whether the fully human IgM monoclonal antibody PAT-SM6 that targets a tumour-specific variant of the heat shock protein GRP78 might be an attractive candidate for future immunotherapeutic approaches. We here show that GRP78 is stably and consistently expressed on the surface on tumour cells from patients with de novo, but also relapsed MM and that binding of PAT-SM6 to MM cells can specifically exert cytotoxic effects on malignant plasma cells, whereas non-malignant cells are not targeted. We demonstrate that the induction of apoptosis and, to a lesser extent, complement dependent cytotoxicity is the main mode of action of PAT-SM6, whereas antibody dependent cellular cytotoxicity does not appear to contribute to the cytotoxic properties of this antibody. Given the favourable safety profile of PAT-SM6 in monkeys, but also in a recent phase I trial in patients with malignant melanoma, our results form the basis for a planned phase I study in patients with relapsed MM.}, language = {en} } @article{KiemLeischNeureiteretal.2021, author = {Kiem, Dominik and Leisch, Michael and Neureiter, Daniel and Haslauer, Theresa and Egle, Alexander and Melchardt, Thomas and Topp, Max S. and Greil, Richard}, title = {Two cases of pancytopenia with Coombs-negative hemolytic anemia after chimeric antigen receptor T-cell therapy}, series = {International Journal of Molecular Sciences}, volume = {22}, journal = {International Journal of Molecular Sciences}, number = {11}, issn = {1422-0067}, doi = {10.3390/ijms22115449}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-284977}, year = {2021}, abstract = {Background: Chimeric antigen receptor (CAR) T-cells are changing the therapeutic landscape of hematologic malignancies. Severe side effects include cytokine release syndrome (CRS) and immune effector cell-associated neurotoxicity syndrome (ICANS), but prolonged cytopenia has also been reported. The underlying mechanism for prolonged cytopenia is poorly understood so far. Cases: Severe pancytopenia with grade 2-3 anemia was marked 2-3 months after treatment. Laboratory evaluation revealed undetectable levels of haptoglobin with increased reticulocyte counts. Coomb's tests were negative, no schistocytes were detected on blood smear, and infectious causes were ruled out. Increased erythropoiesis without lymphoma infiltration was noted on bone marrow biopsy. A spontaneous increase in haptoglobin and hemoglobin levels was observed after several weeks. For one patient, peripheral CAR-T levels were monitored over time. We observed a decline at the same time as hemoglobin levels began to rise, implying a potential causality. Conclusion: To our knowledge, we describe the first two cases of Coombs-negative hemolytic anemia after CAR-T treatment for B-cell lymphoma. We encourage routine monitoring for hemolytic anemia after CAR-T treatment and also encourage further investigations on the underlying mechanism.}, language = {en} } @article{BergesKerkauWerneretal.2016, author = {Berges, Carsten and Kerkau, Thomas and Werner, Sandra and Wolf, Nelli and Winter, Nadine and H{\"u}nig, Thomas and Einsele, Hermann and Topp, Max S. and Beyersdorf, Niklas}, title = {Hsp90 inhibition ameliorates CD4\(^{+}\) T cell-mediated acute Graft versus Host disease in mice}, series = {Immunity, Inflammation and Disease}, volume = {4}, journal = {Immunity, Inflammation and Disease}, number = {4}, doi = {10.1002/iid3.127}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-168318}, pages = {463-473}, year = {2016}, abstract = {Introduction: For many patients with leukemia only allogeneic bone marrow transplantion provides a chance of cure. Co-transplanted mature donor T cells mediate the desired Graft versus Tumor (GvT) effect required to destroy residual leukemic cells. The donor T cells very often, however, also attack healthy tissue of the patient inducing acute Graft versus Host Disease (aGvHD)—a potentially life-threatening complication. Methods: Therefore, we used the well established C57BL/6 into BALB/c mouse aGvHD model to evaluate whether pharmacological inhibition of heat shock protein 90 (Hsp90) would protect the mice from aGvHD. Results: Treatment of the BALB/c recipient mice from day 0 to +2 after allogeneic CD4\(^{+}\) T cell transplantation with the Hsp90 inhibitor 17-(dimethylaminoethylamino)-17-demethoxygeldanamycin (DMAG) partially protected the mice from aGvHD. DMAG treatment was, however, insufficient to prolong overall survival of leukemia-bearing mice after transplantation of allogeneic CD4\(^{+}\) and CD8\(^{+}\) T cells. Ex vivo analyses and in vitro experiments revealed that DMAG primarily inhibits conventional CD4\(^{+}\) T cells with a relative resistance of CD4\(^{+}\) regulatory and CD8\(^{+}\) T cells toward Hsp90 inhibition. Conclusions: Our data, thus, suggest that Hsp90 inhibition might constitute a novel approach to reduce aGvHD in patients without abrogating the desired GvT effect.}, language = {en} } @article{BedkeIannittiDeLucaetal.2014, author = {Bedke, Tanja and Iannitti, Rossana G. and De Luca, Antonella and Giovannini, Gloria and Fallarino, Francesca and Berges, Carsten and Latg{\´e}, Jean-Paul and Einsele, Hermann and Romani, Luigina and Topp, Max S.}, title = {Distinct and complementary roles for Aspergillus fumigatus-specific Tr1 and \(Foxp3^+\) regulatory T cells in humans and mice}, series = {Immunology and Cell Biology}, volume = {92}, journal = {Immunology and Cell Biology}, number = {8}, doi = {10.1038/icb.2014.34}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-121449}, pages = {659-70}, year = {2014}, abstract = {Unlike induced \(Foxp3^+\) regulatory T cells (\(Foxp3^+\) \(iT_{reg}\)) that have been shown to play an essential role in the development of protective immunity to the ubiquitous mold Aspergillus fumigatus, type-(1)-regulatory T cells (Tr1) cells have, thus far, not been implicated in this process. Here, we evaluated the role of Tr1 cells specific for an epitope derived from the cell wall glucanase Crf-1 of A. fumigatus (Crf-1/p41) in antifungal immunity. We identified Crf-1/p41-specific latent-associated \(peptide^+\) Tr1 cells in healthy humans and mice after vaccination with Crf-1/p41+zymosan. These cells produced high amounts of interleukin (IL)-10 and suppressed the expansion of antigen-specific T cells in vitro and in vivo. In mice, in vivo differentiation of Tr1 cells was dependent on the presence of the aryl hydrocarbon receptor, c-Maf and IL-27. Moreover, in comparison to Tr1 cells, \(Foxp3^+\) \(iT_{reg}\) that recognize the same epitope were induced in an interferon gamma-type inflammatory environment and more potently suppressed innate immune cell activities. Overall, our data show that Tr1 cells are involved in the maintenance of antifungal immune homeostasis, and most likely play a distinct, yet complementary, role compared with \(Foxp3^+\) \(iT_{reg}\).}, language = {en} }
