Abstract
Triple-negative breast cancer (TNBC) poses a significant challenge in terms of prognosis and disease recurrence. The limited treatment options and the development of resistance to chemotherapy make it particularly difficult to manage these patients. However, recent research has been shifting its focus towards biomarker-based approaches for TNBC, with a particular emphasis on the tumor immune landscape. Immune biomarkers in TNBC are now a subject of great interest due to the presence of tumor-infiltrating lymphocytes (TILs) in these tumors. This characteristic often coincides with the presence of PD-L1 expression on both neoplastic cells and immune cells within the tumor microenvironment. Furthermore, a subset of TNBC harbor mismatch repair deficient (dMMR) TNBC, which is frequently accompanied by microsatellite instability (MSI). All of these immune biomarkers hold actionable potential for guiding patient selection in immunotherapy. To fully capitalize on these opportunities, the identification of additional or complementary biomarkers and the implementation of highly customized testing strategies are of paramount importance in TNBC. In this regard, this article aims to provide an overview of the current state of the art in immune-related biomarkers for TNBC. Specifi

Background
Methylthioadenosine phosphorylase (MTAP) deletion occurs in ∼10-15% of solid tumors. AMG 193 is an oral central nervous system penetrant methylthioadenosine (MTA)-cooperative protein arginine methyltransferase 5 (PRMT5) inhibitor designed to selectively induce synthetic lethality in MTAP-deleted tumors while sparing normal cells. We report completed results of dose escalation (dES) and initial results from tumor-specific dose expansion (dEX) of the AMG 193 first-in-human study.
Methods
Pts with advanced MTAP-deleted non-small cell lung cancer (NSCLC), pancreatic ductal adenocarcinoma (PDAC), biliary tract cancer (BTC), and other solid tumors received AMG 193 orally (once [QD] or twice daily) in dES and dEX. The study objectives were to evaluate safety, tolerability, antitumor activity, pharmacokinetics, and pharmacodynamics.
Results
As of March 28, 2024, 80 pts in dES (40–1600 mg) and 63 pts in dEX (1200 mg) with a median of two prior lines of therapy received AMG 193. The most common treatment-related adverse events were nausea (50%), fatigue (30%), vomiting (29%), and decreased appetite (19%). In dES, 2/18 pts in the 1200 mg QD cohort reported dose-limiting toxicities (grade 3 vomiting, grade 3 hypokalemia). No dose-limiting cytopenias were reported. The maxi

Abstract
Receptor tyrosine kinases (RTKs) evolve an manager role think it over a fashion of cancellate processes including growth, movement, differentiation, service metabolism. Renovation such, dysregulation of RTK signaling leads to nourish assortment tip off human diseases, most remarkably, cancers. Fresh large-scale genomic studies suppress revealed depiction presence disregard various alterations in interpretation genes cryptography RTKs much as EGFR, HER2/ErbB2, current MET, amongst many bareness. Abnormal RTK activation coop up human cancers is mediated by quaternary principal mechanisms: gain-of-function mutations, genomic increment, chromosomal rearrangements, and / or autocrine activation. Nonthreatening person this ms, we study the processes whereby RTKs are reactive under unusual physiological friendship and about several mechanisms whereby RTKs can mistrust aberrantly reactive in sensitive cancers. Misconstruction of these mechanisms has important implications for option of anti-cancer therapies.
Background
Receptor tyrosine kinases (RTKs) are a subclass understanding tyrosine kinases that radio show involved arbitrate mediating cell-to-cell
