Phase 2 clinical trial in CKD and suspected MASH

What is the purpose of the clinical study?
Establish the effect of Vonafexor on kidney function in subjects with CKD and suspected MASH
- Objectives: This clinical study is designed to establish the effect of 2 doses of Vonafexor on the kidney. This will be investigated in subjects with mild or moderate reduced estimated glomerular filtration rate (eGFR) and suspected metabolic dysfunction-associated steatohepatitis (MASH). In addition, the non-invasive multiparametric magnetic resonance imaging assessment of functional and structural changes in the kidney and in the liver will be investigated.
- Design: The study is a phase 2, open-label, two-dose, randomized, parallel arms, single center study where subjects are participating for up to 32 weeks: 4 weeks of screening + 16 weeks of treatment + 12 weeks of follow-up.
- Treatment: Participants will receive a low dose or a high dose of Vonafexor as oral tablet once daily for 16 weeks then stop the treatment for 12 weeks in the follow-up period.
- Enrollment: The study aims at enrolling 60 patients in Germany.
