Market Dynamics and Patent Landscape for ATC Class L01EK: Vascular Endothelial Growth Factor Receptor (VEGFR) Tyrosine Kinase Inhibitors
Summary
The ATC (Anatomical Therapeutic Chemical) classification code L01EK encompasses vascular endothelial growth factor receptor (VEGFR) tyrosine kinase inhibitors (TKIs), a pivotal class of targeted therapies mainly employed in oncology to inhibit tumor angiogenesis.
