DDR-Defective Tumors Market New Product Development & Latest Trends

Introduction
DNA Damage Response (DDR) pathways are critical for maintaining genome integrity. When these pathways are defective, mutations accumulate, leading to tumor development. DDR-defective tumors are cancers associated with impaired DNA repair mechanisms, often linked to mutations in BRCA1, BRCA2, ATM, CHEK2, PALB2, and related genes. Such defects are common in breast, ovarian, prostate, and pancreatic cancers, among others.

Targeting DDR pathways has become one of the most exciting frontiers in oncology. The success of poly (ADP-ribose) polymerase (PARP) inhibitors has established DDR as a cornerstone of precision oncology. Beyond PARP, newer therapies targeting ATR, DNA-PK, and WEE1 kinases are in active clinical development, promising to expand the therapeutic arsenal. Combined with advances in companion diagnostics and biomarker-driven treatment strategies, the DDR-defective tumors market is set for robust growth over the next decade.
