Innovent Biologics Inc. unveiled for the first time safety and efficacy data of IBI-354, an HER2 monoclonal antibody-camptothecin derivative conjugate that shows promising efficacy signals across a range of advanced solid tumors, during the European Society of Medical Oncology (ESMO) 2024 Congress. An HER2-targeted antibody-drug conjugate developed using Innovent's topoisomerase inhibitor NT3 platform, IBI-354 combines a hydrophilic linker design with a hydrophobic payload to enhance the bystander effect, targeting adjacent antigen-low or negative tumor cells.

Scattered investor qualms about Nuvalent Inc.’s largely upbeat data during the European Society for Medical Oncology (ESMO) meeting in Barcelona didn’t stop the firm from pricing an upsized $500 million public offering. The Cambridge, Mass.-based firm is selling 5 million shares of class A common stock at $100 each. The offering is expected to close on Sept. 18, with underwriters holding a 30-day option to purchase up to 750,000 more shares.

One of the current challenges of immunotherapy is the hunt for good targets, and the Claudins – a family of roughly two dozen transmembrane proteins – would appear to have a lot going for them. “Some Claudins distribute in a tissue-specific manner, and malignant transformation causes their exposition,” Cinta Hierro told the audience at the European Society of Medical Oncology (ESMO) 2024 Congress. “Others are rarely expressed in healthy tissue.”

UL16 binding protein 6 (ULBP6) is a molecule belonging to the stress-induced NKG2D ligand family and its expression is up-regulated on the surface of cancerous cells, binding to the immune-activating NKG2D receptor on natural killer (NK) and T cells, thus promoting immune evasion.

Metastatic solid tumors may be curable now. Among the most profound results presented over the weekend at the European Society for Medical Oncology (ESMO) 2024 Congress were the 10-year data from the Checkmate-067 and Keynote-006 trials, the phase III trials that tested Opdivo (nivolumab, Bristol Myers Squibb Co.) and Keytruda (pembrolizumab, Merck & Co. Inc.) as first-line agents in advanced or metastatic melanoma.

Two weeks after reporting positive top-line results in first-line head and neck cancer with its lead candidate, eftilagimod alfa, in combination with Merck & Co. Inc.’s Keytruda (pembrolizumab), Immutep Ltd. presented updated data indicating the treatment could offer a non-chemotherapy option for patients with negative PD-L1 expression. Data from cohort B of the Tacti-003 (Keynote-PNC-34) phase IIb trial, which included 31 evaluable patients with PD-L1 expression of less than 1, as measured by Combined Proportion Score, showed a 35.5% objective response rate per RECIST 1.1 assessment.
