Scientists Develop New Drug to Target 'Undruggable' Pancreatic Cancer, Doubling Survival Rates
Researchers have made a significant breakthrough in the treatment of pancreatic cancer, a disease known for its low survival rates. A new drug, daraxonrasib, has been developed to target the KRAS gene mutation, which is responsible for over 90% of pancreatic tumors. This mutation causes the KRAS protein to remain in a constant 'on' state, leading to uncontrolled cell growth. Historically, KRAS has been considered 'undruggable' due to its smooth surface, which lacks binding sites for drugs. However, daraxonrasib works by binding to cyclophilin A, a molecule that assists in protein folding, thereby inhibiting KRAS activity. In a Phase 3 clinical trial involving 500 patients with metastatic pancreatic cancer, daraxonrasib nearly doubled the median survival time from 6.7 to 13.2 months compared to standard chemotherapy. The drug also reduced the risk of death by 60%. Common side effects include skin rash, stomatitis, and gastrointestinal issues, but these are less severe than those associated with chemotherapy...
