Priority Review Granted for Trastuzumab Deruxtecan; Would Be First Tumor-Agnostic ADC

A tumor-agnostic approval would be a significant development in the advance of antibody-drug conjugates (ADCs), which are designed to deliver a potent, cancer-fighting payload into a tumor while sparing nearby tissues.

January 30, 2024 9:00 am

Clearity’s Perspective: Most drugs are tested and approved to treat cancers based on where in the body the cancer started and the type of tissue from which it developed. Enhertu (Trastuzumab Deruxtecan, T-Dxd), a HER2-targeted antibody drug conjugate (ADC), already … Read more

Diagnosing the “Silent Killer”: AI Tackles Early Stage Ovarian Cancer

January 26, 2024 9:00 am

By Fay Lin, PhD

A major bottleneck in early detection is the molecular heterogeneity between ovarian cancer (OC) patients, which limits the likelihood of identifying individual biomarkers that are shared among patients. In a new study “A personalized probabilistic … Read more
