New Kidney Repair Drug Shows Promise After Breakthrough Study
Scientists have identified a promising kidney repair drug that could improve healing after kidney injury. The treatment worked well in mice and may support future therapies for chronic kidney disease. Researchers at UCLA developed the drug to repair heart damage first. However, they later discovered it also helped injured kidneys recover faster.
Scientists Discover a Barrier to Kidney Healing
The research team found that injured kidneys produce a protein called ENPP1. This protein disrupts energy production and slows natural healing. Researchers also examined kidney samples from people with chronic kidney disease. They found much higher ENPP1 levels than in healthy kidneys. Next, scientists tested mice with kidney injuries. Some mice lacked ENPP1, while others produced it normally. Blood tests showed kidney damage in every mouse at first. However, mice without ENPP1 recovered much faster over four weeks. Researchers then treated injured mice with AD-NP1. This laboratory-made antibody blocks ENPP1 and protects healthy tissue. The treated mice showed stronger kidney function after one week. They also developed less scar tissue during recovery. Scientists observed more healthy cell growth in treated kidneys. As a result, damaged tissue repaired itself more effectively.
Drug Could Support Future Human Treatments
Researchers originally created AD-NP1 to repair heart tissue after heart attacks. Now, the findings suggest it may also benefit kidney recovery. The drug has already received approval for a Phase 1 heart disease trial. These studies will evaluate safety and proper dosing in humans. The research team also hopes to begin kidney clinical trials soon. If successful, the therapy could offer a new option for millions living with kidney disease. Although the results remain early, they provide strong encouragement. Future human studies will determine whether the treatment delivers similar benefits in patients.
