However, frequent intravenous administration of clotting factor products, blood access, and development of alloantibodies (inhibitors) have been important issues. Clinical studies aimed at addressing these issues have been conducted in Japan as well, including a multicenter study to determine factors involved in inhibitor development. Drug development has also progressed: several clotting factor products with extended half-life and non-clotting factor therapies have been introduced in quick succession. Anti-FIX/FX bispecific antibody in particular has a long half-life when administered subcutaneously and controls bleeding in patients with hemophilia A. Anti-antithrombin therapy and anti-TFPI monoclonal antibody products that work by rebalancing coagulation have also been developed. In addition, gene therapy has been approved for adults in U.S. and Europe, where improved vectors and codon optimization have enabled protein expression up to the near-therapeutic hemostatic range. Recent significant developments in hemophilia treatment are expected to overcome long-standing problems and further improve QOL.","PeriodicalId":93844,"journal":{"name":"[Rinsho ketsueki] The Japanese journal of clinical hematology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142367790","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

CAR T-cell therapy is now approved in Japan and has become one of the essential therapeutic options for chemotherapy-resistant disease. It has many unique features that distinguish it from conventional chemotherapies, including the limitations imposed by the production of CAR-T cells from autologous T cells, and the limited availability and mandatory waiting period for treatment. Importantly, each patient has only one opportunity to receive CAR T-cell therapy. To achieve the maximum therapeutic benefit from CAR T-cell therapy, it is necessary to understand all aspects of CAR T-cell therapy, including factors that influence its efficacy. The design of the entire treatment sequence, including before and after CAR T-cell therapy, is also important to optimize clinical outcomes. In addition, since this treatment is only available at a limited number of facilities, effective coordination between local hospitals and treatment centers is also important. This educational session will focus on the practical aspects of CAR T-cell therapy in adults and will provide indispensable knowledge for providing CAR T-cell therapy to patients with B-cell lymphoma and multiple myeloma.","PeriodicalId":93844,"journal":{"name":"[Rinsho ketsueki] The Japanese journal of clinical hematology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142367826","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

B-cell maturation antigen (BCMA)-targeted immunotherapy, including chimeric antigen receptor T-cell therapy (CAR-T) and bispecific antibodies (BsAbs), is emerging as another important class of treatment. Two BCMA-targeting CAR-T products, idecabtagene vicleucel (ide-cel) and ciltacabtagene autoleucel, are approved in Japan, but only ide-cel is available for clinical use. Recently, a randomized phase III study comparing ide-cel with standard therapy in patients with refractory myeloma who had received 2 to 4 prior lines of therapy showed that ide-cel was superior in terms of both response rate and PFS. Based on these results, ide-cel was approved as a third-line therapy. The new availability of bispecific antibodies has also raised new clinical questions regarding how to use CAR-T and BsAbs for each patient, and in what order. Limited data have suggested that favorable responses can be achieved when BsAbs are administered after CAR-T, but responses are suboptimal when CAR-T is administered after BsAbs. Finally, it is important to note that coordination between referring centers and treating centers, including aspects such as timing of patient referral, bridging therapy, and long-term follow-up after CAR-T, is critical to optimization of CAR-T.","PeriodicalId":93844,"journal":{"name":"[Rinsho ketsueki] The Japanese journal of clinical hematology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142367829","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Patient 2 was a 65-year-old man with relapsed angioimmunoblastic T-cell lymphoma who received bone marrow transplantation from an HLA-DR single-antigen-mismatched unrelated donor. Lower back pain appeared on day30, and L4-L5 pyogenic spondylitis was diagnosed based on MRI. Blood culture was negative. Daptomycin and clindamycin were selected for treatment based on the drug susceptibility of bacteria that had caused pre-engraftment BSI (Escherichia coli on day3 and Corynebacterium striatum on day9), and the pyogenic spondylitis resolved after 6 months of this treatment.

In addition to driver gene mutations, which are also found in clonal hematopoiesis in healthy elderly people, systemic inflammation caused by infection or collagen disease has long been known as an extracellular factor in the pathogenesis of MDS. Wild-type HSCs have an \"innate immune memory\" that functions in response to infection and inflammatory stress, and my colleagues and I used an infection stress model to demonstrate that the innate immune response by the TLR-TRIF-PLK-ELF1 pathway is similarly critical in impairment of hematopoiesis and dysregulation of chromatin in MDS stem cells. This revealed that not only are MDS stem cells expanded by the TRAF6-NF-kB pathway, the innate immune response is also involved in generating MDS stem cells. In this review, I will present research findings related to \"innate immune memory,\" one of the pathogenic mechanisms of blood cancer, and discuss future directions for basic pathological research and potential therapeutic development.","PeriodicalId":93844,"journal":{"name":"[Rinsho ketsueki] The Japanese journal of clinical hematology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141891241","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
