New hope for kidney patients: experimental drug targets protein leak
NCT ID NCT05267262
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested an experimental drug called R3R01 in 43 people with two rare kidney diseases (Alport syndrome and focal segmental glomerulosclerosis) whose protein in urine remained high despite standard treatment. The main goals were to check safety and see if the drug could reduce protein leakage from the kidneys. Results will help decide if larger studies are warranted.
