Newco Yellowstone Biosciences Ltd. has been formed to develop soluble bispecific T-cell receptors against a novel class of tumor-specific antigens it has discovered in leukemia patients who were cured by a donor stem cell transplant. The company has proprietary access to a biobank of over 10,000 samples from more than 3,000 acute myeloid leukemia (AML) patients. A small number of these patients were cured by an allogeneic bone marrow transplant, whilst unusually, having no sign of graft-vs.-host disease.
Residual leukemic stem cells (LSCs) are leukemia relapse-initiating cells that mediate treatment resistance in response to therapy stress. Different from normal hematopoietic stem cells (HSCs), both blasts and LSCs express T-cell immunoglobulin mucin-3 (TIM-3) on the surface.
Targeting topoisomerase 2 (TOP2) is crucial in AML, and researchers from Wakunaga Pharmaceutical Co. Ltd. have developed and tested racemic WAC-224, a quinolone TOP2 inhibitor, and (R)-WAC-224 as a potential approach for AML treatment.
Yellowstone Biosciences Ltd. has launched with a focus on soluble bispecific T-cell receptor (TCR)-based therapies for human leukocyte antigen (HLA) class II (HLA-II) targets in oncology.
Among the acquired mutations in the calreticulin (CALR) gene, both 52 bp deletion (del52) and 5 bp insertion (ins5) are among the most frequent and are linked to two different types of myeloproliferative neoplasms (MPNs).
During the basic science morning track on the last day of this year’s Annual Congress of the European Hematology Association (EHA), the attention was focused on oncogenic transcription factors and complexes considered turning points within the acute myeloid leukemia (AML) arena.
Scientists at Chungnam National University assessed the role of estrogen-related receptor α (ERRα) in the context of acute myeloid leukemia (AML). First, it was demonstrated that ERRα expression levels were increased in bone marrow of patients with AML as compared to normal control patients, and that patient survival was significantly correlated with ERRα expression.
Researchers from Lund University presented data from a study that aimed to identify novel targets for immunotherapy in acute myeloid leukemia (AML). To identify differentially expressed cell surface proteins in the primitive CD34+CD38- cell populations, an arrayed antibody screen was performed on primary bone marrow samples from patients with AML as well as healthy donors.
