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.
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).
A new approach against non-small-cell lung cancer (NSCLC) has combined immunotherapy with molecularly targeted therapy to activate the immune response and inhibit oncogenic pathways, which prevented tumor progression and eliminated cancer cells. Brigham and Women’s Hospital scientists have developed nanoparticles loaded with antibody conjugates that could deliver large amounts of treatment to the tumor tissue. This new strategy could improve the results of conventional immunotherapy in these patients and reduce toxicity of existing treatments.
Day One Biopharmaceuticals Inc. has entered into an exclusive licensing agreement with Mabcare Therapeutics for MTX-13, a novel antibody-drug conjugate (ADC) targeting protein-tyrosine kinase 7 (PTK7). Under the agreement, Day One has exclusive rights to develop, manufacture and commercialize MTX-13 (now DAY-301), worldwide, excluding Greater China.
The adverse effects of PD-1 blockers on the CNS observed in cancer patients could occur through their effects on an enzyme that activates microglia. Pharmacological inhibition of the enzyme in mice reduced microglial activation and cognitive deficit without altering the antitumor capacity of the immunotherapy.
Zymeworks Inc. has obtained IND clearance from the FDA for ZW-171, a novel T-cell targeting bispecific antibody for mesothelin (MSLN)-expressing cancers. Clinical development will begin this year, and additional applications will be filed in the second half of the year seeking trial clearances in other territories.
Sonnet Biotherapeutics Holdings Inc. has announced the generation and in vitro characterization of two novel drug candidates, SON-1411 (IL18BPR-FHAB-IL12) and SON-1400 (IL18BPR-FHAB), each containing a modified version of recombinant human interleukin (IL)-18 (IL-18 binding protein resistant [IL-18BPR]).
Bivictrix Therapeutics plc’s BVX-001, a first-in-class Bi-Cygni bispecific antibody-drug conjugate (ADC) for the treatment of acute myeloid leukemia (AML), has demonstrated a favorable toxicity profile in an industry standard toxicology model.
Hudson Therapeutics Inc., a U.S. subsidiary of Shaperon Inc., has announced the signing of a memorandum of understanding (MOU) between Shaperon and Dong-A ST Co. Ltd. for the development of nanobody-based new drugs.
