A phase II study of zandelisib in patients with relapsed or refractory indolent non-Hodgkin lymphoma: ME-401-K02 study.

Zandelisib, a selective, potent PI3Kδ inhibitor, demonstrated favourable outcomes in patients with relapsed or refractory follicular lymphoma in a global phase II study. This phase II study evaluated the efficacy and safety of zandelisib for relapsed or refractory follicular lymphoma or marginal zone lymphoma. Sixty-one patients received zandelisib orally at 60 mg daily continuously in the first two 28-day cycles, followed by intermittent dosing on Days 1-7 following each cycle until progressive disease or unacceptable toxicity.

Evaluation of the effect of cell freshness on pyrogen detection using a serum-free monocyte-activation test.

Pyrogens cause shock symptoms when released into the bloodstream. They are classified into two main categories: endotoxins (lipopolysaccharides [LPS]) and non-endotoxin pyrogens. The monocyte activation test (MAT) is an in vitro assay to detect pyrogens in human monocytes.

Whole exome sequencing analysis of a patient with myeloid/lymphoid neoplasms with eosinophilia and tyrosine kinase gene fusions with ETV6::LYN fusion gene.

ETV6::LYN fusion gene is recognized as one of the genetic alterations responsible for myeloid/lymphoid neoplasms with eosinophilia and tyrosine kinase gene fusions (MLN-TK) according to the 2022 WHO classification. However, the clinical features and pathogenesis of MLN-TK with ETV6::LYN are not well defined because of the rarity of the disease. Here, we report an MLN-TK patient with ETV6::LYN that manifested as myeloproliferative neoplasms (MPN) with eosinophilia, myelofibrosis, and T-lymphoblastic lymphoma (T-LBL), which eventually led to acute myeloid leukemia.

Valemetostat for patients with relapsed or refractory peripheral T-cell lymphoma (VALENTINE-PTCL01): a multicentre, open-label, single-arm, phase 2 study.

Background: Peripheral T-cell lymphomas are aggressive non-Hodgkin lymphomas with few treatment options for relapsed or refractory disease. Valemetostat tosylate (valemetostat) is a potent, novel, dual inhibitor of EZH2 and EZH1. We investigated the clinical activity and safety of valemetostat in patients with relapsed or refractory peripheral T-cell lymphoma, and its safety in patients with relapsed or refractory adult T-cell leukaemia/lymphoma.
