Breast cancer cells, when disseminated to other secondary organs such as the lungs, may stay in a dormant state for years, even decades. But the mechanisms that limit their expansion are not well understood. This is what researchers call a dormant mesenchymal-like phenotype before metastasis to the lungs. Now, scientists have shown in a study published Oct. 7, 2024, in Cell, that the limiting of disseminated breast cancer cells (DCCs) to metastasize in the lungs is due to alveolar macrophages, which activate signals that make DCCs stay dormant.

But the mechanisms that limit their expansion are not well understood. This is what researchers call a dormant mesenchymal-like phenotype (M-like) before metastasis to the lungs. Now, scientists have shown in a study published Oct. 7, 2024, in Cell, that the limiting of disseminated breast cancer cells (DCCs) to metastasize in the lungs is due to alveolar macrophages (AMs), which activate signals that make DCCs stay dormant.
Survival in metastatic breast cancer has increased in recent years, but 5-year survival rates remain below 50% and the mechanisms of spreading remain to be elucidated. An emerging strategy to inhibit the progression of tumors consists of acting on tumor-associated macrophages to displace them from an M2-like phenotype to an M1-like phenotype.
Biontech SE and Duality Biologics Co. Ltd. have progressed BNT-323/DB-1303 to pivotal phase III trials, beginning in China in patients with hormone receptor-positive and HER2-low metastatic breast cancer.
U.S. biopharma Sermonix Pharmaceuticals Inc. handed off China rights of lasofoxifene, an oral endocrine therapy in development for breast cancer, to Shanghai’s Henlius Biotech Inc., for an undisclosed up-front payment and up to $58 million in milestone fees.

Half of patients with HER2-positive advanced breast cancer develop metastases in the central nervous system (CNS), even while receiving HER2-directed therapies.
Immutep Ltd. announced an AU$80 million (US$52.1 million) capital raise that consists of a AU$50 million placement and a AU$30 million entitlement offer to eligible shareholders to fund clinical programs for lead candidate eftilagimod (IMP-321, efti), a lymphocyte activation gene-3 (LAG-3) fusion protein and major histocompatibility complex class II agonist that stimulates both innate and adaptive immunity for treating cancer.

Biotechnology startup Reveal Genomics SL said that a study, published in Nature Communication, found its machine learning-based technology applied to circulating tumor DNA (ctDNA) is able to predict drug response and survival outcome in patients with metastatic breast cancer treated with endocrine therapy and CDK4/6 inhibitors.
