Summary
"This trial is testing how safe vonafexor is and how it affects kidney function in people with Alport syndrome who are at risk of their condition getting worse."
Who is the study for?
This trial is for people with Alport syndrome at risk of kidney function decline. Participants must have certain levels of kidney function, no hepatitis B/C or HIV, use contraception if applicable, and be on stable treatments for related conditions. Pregnant individuals or those with recent serious illnesses are excluded.
What is being tested?
The study tests the safety and impact of vonafexor on kidney function in Alport syndrome patients. It's a proof-of-concept trial to see how well this drug works and what effects it has on those who might face worsening kidney health.
What are the potential side effects?
While specific side effects aren't listed here, participants will be monitored for any adverse reactions to vonafexor which could include typical drug responses such as digestive issues, allergic reactions, changes in liver enzymes or other organ-related complications.
