In short
KRAS inhibitors are medicines designed to block the KRAS protein, which helps cancer cells grow [1]. They are currently being studied in clinical trials for pancreatic cancer [6]. These drugs work best when combined with other treatments to stop the cancer from becoming resistant [2].
The details
* Most pancreatic cancers have mutations in the KRAS gene, making it a key target for therapy [1].
* Older KRAS inhibitors, like sotorasib and adagrasib, only work on the G12C mutation, which is rare in pancreatic cancer (found in only 2%-3% of cases) [1].
* Newer drugs, such as MRTX1133 and HRS-4642, target the more common G12D mutation found in many patients [1], [4].
* Other new KRAS G12D inhibitors, including RNK08594 and GFH375, are also being tested in early clinical studies [6].
* Cancer cells often develop resistance to these drugs over time by changing their genetic makeup or cell state [2], [8].
* Combining KRAS inhibitors with chemotherapy or other drugs like nimotuzumab can help overcome this resistance and improve tumor control [2], [4].
What to know
These treatments are still largely in the early stages of development and clinical trials [1], [6]. Resistance to these drugs is a major challenge because pancreatic cancer biology is complex [3].
