IgE is known to drive allergic disease, and omalizumab is the only approved anti-IgE antibody to date that has shown suboptimal IgE affinity and limited use in scenarios with high IgE levels.

A new isoform of proliferating cell nuclear antigen (PCNA) – cancer-associated PCNA (caPCNA) – that is specifically expressed in cancer tissues has been reported. Because cancer cells and HIV-infected cells have similar features, researchers from City of Hope National Medical Center tested the anit-HIV effects of a small-molecule compound, AOH-1996, that targets caPCNA.

Oddsmakers wasted no time figuring the market chances after Merck & Co. Inc. rolled out data from the phase III Litespark-011 study testing its oral hypoxia-inducible factor-2 alpha (HIF-2α) inhibitor, Welireg (belzutifan), when used with tyrosine kinase inhibitor Lenvima (lenvatinib, Eisai Co.) in advanced renal cell carcinoma.

Calidi Biotherapeutics Inc. recently presented data regarding CLD-401 as an immunotherapeutic approach developed using the Redtail gene therapy platform. This platform uses a tumor-specific, replicating enveloped vaccinia virus that expresses a chimeric form of CD55 to allow complement and neutralizing antibody resistance, as well as systemic administration.

Researchers from Sutro Biopharma Inc. presented data on dual-payload antibody-drug conjugates (ADCs) engineered to overcome drug resistance, demonstrating enhanced cytotoxicity and potential efficacy in resistant cancer models.

Mitogen-activated protein kinase kinase kinase kinase 1 (HPK1) is a serine/threonine protein kinase that is expressed in the hematopoietic compartment, exerting regulatory functions in myeloid and innate immune cells. It has been associated with decreased T-cell activation and proliferation.

Broadly neutralizing antibodies (bNAbs) target conserved HIV envelope regions to neutralize diverse strains, eliminate infected cells and reduce viral reservoirs, complementing antiretroviral therapy and supporting prevention and functional cure strategies.

Autoantibodies and B cells are drivers of progressive autoimmune diseases, but targeting B cells or plasma cells alone is not sufficient to address them. Earendil Labs has presented data on HXN-1031, a novel T-cell engager targeting both CD19 and B-cell maturation protein (BCMA).

At Biocom’s Global Partnering and Investor Conference, representatives from the business development departments at various pharmaceutical companies provided an update on their appetites for deals. The mood was fairly upbeat because, let’s face it, large pharma has become dependent on external development.

G-protein coupled receptor 68 (GPR68) is an acid-sensing protein receptor that has been implicated in inflammatory bowel disease (IBD) pathogenesis by its modulation of the inflammatory response and fibrosis.
