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.

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.
Genentech Inc. didn’t need to wait until Thanksgiving for the U.S. FDA to make up its mind. More than a month ahead of its PDUFA date, the agency approved the firm’s first-line breast cancer treatment, Itovebi (inavolisib), providing the oral therapy a place with other niched therapies from Astrazeneca plc and Novartis AG. Itovebi is to be combined with Pfizer Inc.’s palbociclib (Ibrance) and Faslodex (fulvestrant, Astrazeneca) for adults with endocrine-resistant, PIK3CA-mutated, hormone receptor (HR)-positive, HER2-negative, locally advanced or metastatic breast cancer.
Investigators at Nanjing Medical University and The University of Texas MD Anderson Cancer Center recently published data from their research that aimed to identify novel immunotherapy targets in triple-negative breast cancer (TNBC).
At this week’s American Society for Radiation Oncology meeting, scientists from The University of Texas MD Anderson Cancer Center reported the discovery and preclinical evaluation of CD47-LLO, a novel microbial-inspired antibody-drug conjugate (ADC) for the treatment of cancer.
Owkin Inc. partnered with Astrazeneca plc to develop an artificial intelligence (AI)-powered tool to pre-screen for germline BRCA mutations (gBRCAm) in breast cancer directly from digitized pathology slides. The companies hope that the gBRCA pre-screening solution will not only transform patients’ lives but bring value to health care systems.
Ichnos Glenmark Innovation (IGI) has announced a cooperative research and development agreement (CRADA) with the National Cancer Institute (NCI) to evaluate IGI’s selective, orally active Casitas B-lineage lymphoma b (Cbl-b) inhibitor GRC-65327.
Scientists at Inventisbio Co. Ltd. and Inventisbio LLC have divulged phosphatidylinositol 3-kinase α (PI3Kα) (E545K mutant) inhibitors reported to be useful for the treatment of cancer, PIK3CA-related overgrowth spectrum and congenital lipomatous overgrowth, vascular malformations, epidermal naevi and skeletal abnormalities (CLOVES syndrome).
Innate Pharma SA has obtained IND clearance from the FDA for IPH-4502, its novel and differentiated topoisomerase I inhibitor antibody-drug conjugate (ADC) conjugated to exatecan targeting Nectin-4 in solid tumors. In nonclinical models, IPH-45 was well tolerated and showed antitumor efficacy in vitro and in vivo.
Impact Therapeutics (Shanghai) Inc. has disclosed tricyclic derivatives acting as poly(ADP-ribose) polymerase 1 (PARP-1; ARTD1) inhibitors reported to be useful for the treatment of cancer.
