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.
For Jeff Galvin, the CEO and founder of newly launched Addimmune Inc., HIV is not a condition that’s in the rearview mirror. It needs a functional cure to save lives, make people healthier and save money that need not have been spent. People wonder why it’s worth bothering to cure HIV, Galvin told BioWorld, when they are taking their medications every day and they are feeling pretty close to normal. But it’s not close for Galvin, who noted that there are side effects from taking the pills that can cause headaches, fatigue, nausea and diarrhea.
Urinary tract infections (UTIs) are often recurrent. The organism does not always establish an effective line of defense that protects from reinfection. The key lies in two reservoirs of bacteria and how tissue-resident memory T cells (TRMs) trigger the immune response. A recent paper from the Pasteur Institute in France describes how these cells mediate immunity to defeat reinfection.
Regulatory T-cell specialist Dualyx NV has closed a €40 million (US$43.5 million) series A to progress the lead autoimmune disease program to the clinic and to take forward two other Treg-based therapies. The company brings together expertise in antibody design with understanding of the role Tregs play in supressing the immune response to maintain homeostasis and self-tolerance, preventing autoimmunity.
