Immunotherapy based on T cells is the vanguard of cancer treatments. Researchers from Washington University in St. Louis have shown that similar approaches using T cells could be applied for treating injuries of the central nervous system (CNS). They reported their findings in Nature on Sept. 4, 2024.
Immatics NV’s IMA-203 “looks like a melanoma drug,” said Cantor Fitzgerald analyst Eric Schmidt after he took a peek at the latest data, prepared as part of an upcoming meeting with the U.S. FDA. The candidate emerged from Immatics’ Actengine platform, set up to formulate a personalized therapy in which a patient’s own T cells are collected, genetically modified and then reinfused. Immatics offered data with IMA-203 as a monotherapy that targets preferentially expressed antigen in melanoma from an ongoing phase I trial testing what’s been established as the recommended phase II dose of 1-10x109 TCR-T cells in 30 heavily pretreated metastatic melanoma patients who were evaluable for efficacy.
The COVID-19 virus may keep mutating, but new findings from Korean researchers at the Institute of Basic Science (IBS) offer a silver lining: human immunity is adapting, too.
Umoja Biopharma Inc.’s gene delivery platform that combines a third-generation lentiviral vector gene approach with a novel T-cell targeting and activation surface complex brought Abbvie Inc. to the table for a pair of deals that could be worth as much as $1.44 billion.
Scientists at the University of California San Francisco (UCSF) have designed a group of synthetic molecules that could prevent the rejection of allogeneic cell transplants. Their strategy consisted of activating the immune checkpoints of different populations of immune cells from the cell surface, but avoiding the cytotoxicity of natural killer (NK) cells and macrophages that would destroy the transplanted cells.
Aboleris Pharma has closed a €27.3 million (US$28.7 million) series A financing, funds it plans to put toward progressing into the clinic a monoclonal antibody against a novel T-cell target with “first-in-class potential” to treat rheumatoid arthritis. The Gosselies, Belgium-based company’s antibody, ABO-21009, is designed to “rebalance” the immune system by inhibiting CD45RC, a protein expressed on the surface of a subset of disease-causing T cells.
Previous research has validated hematopoietic progenitor kinase 1 (HPK1) as a target in immune oncology, and pharmacological inhibition of HPK1 has been shown to enhance effector T-cell function and antitumor activity.
Abcuro Inc. pulled down an oversubscribed $155 million series B financing co-led by Redmile Group and Bain Capital Life Sciences to advance cytotoxic T and natural killer cells therapies. Specifically, proceeds will back the phase II/III registrational trial of ABC-008, a first-in-class anti-killer cell lectin-like receptor G1 (KLRG1) antibody for inclusion body myositis (IBM) as well as fund continued development of other clinical programs.
Pursuing tumor-infiltrating lymphocytes (TILs), Turnstone Biologics Inc. raised about $80 million in an IPO, offering 6.7 million shares at $12 each. The firm is “pioneering a differentiated approach to TILs,” with next-generation products designed by choosing the most potent and tumor-reactive T cells, dubbed Selected TILs, according to SEC paperwork.
Interactions between the gut microbiome and immune system influence cancer immune surveillance, though the mechanism through which these gut-primed immune cells regulate peripheral antitumor immune response is not well understood. Now, two recent studies in Science and Science Immunology using mouse models and human tissue samples have highlighted a group of intestinal T cells with the gut-homing α4β7 integrin receptors that play a critical role in mediating response to immune checkpoint blockade cancer immunotherapy.
