Description
IDE-161 is an experimental drug currently being studied in clinical trials for certain types of advanced solid tumors, including colorectal cancer. It is being investigated specifically in patients whose tumors have BRCA1/2 gene mutations or other problems with the homologous recombination pathway (a way cells repair DNA damage). The goal of the trials is to determine the safe dosage of IDE-161, how it affects the body, and if it shows any early signs of shrinking tumors. In some trials, IDE-161 is also being given together with pembrolizumab (an immunotherapy drug) to see if the combination is effective, particularly in endometrial cancer. It is important to remember that IDE-161 is not yet approved for treating colorectal cancer and is still in early-phase testing.
Mechanism of Action
IDE-161 is a PARG (poly(ADP-ribose) glycohydrolase) inhibitor. PARG is an enzyme involved in DNA repair. By inhibiting PARG, IDE-161 may disrupt the repair of DNA damage, particularly in cancer cells that rely heavily on this pathway, especially those with defects in the homologous recombination pathway like BRCA1/2 mutations. This disruption may lead to increased DNA damage and potentially kill the cancer cells. The specific mechanism and effectiveness are still being investigated in clinical trials.
