Summary

This study tests a drug called exaluren in 24 people aged 12 and older with Alport syndrome caused by specific genetic errors. The drug is given as a daily shot for 32 weeks. Half the group starts exaluren right away, while the other half gets a placebo first and then switches to exaluren. The goal is to see if exaluren can improve kidney health by looking at tiny changes in kidney tissue and protein levels in urine.
